    ABSTRACT: The study of the anatomical variations of the external ear is important for the ear surgeon who assesses the middle ear in this way. Furthermore, the design of insert earmoulds for use with either hearing aids or portable radios requires a better knowledge of the shape of the external ear. We studied the external ear structures and the drumhead in 140 cadavers with no previous history of ear pathology. A silicone resin was used, employing a dental impression technique. These permanent impressions were analysed by means of an operating microscope. Different parameters were studied, to determine the average dimensions of the structures. The clinical significance of these results is discussed.

    ABSTRACT: Forty heavy smokers, all males aged between 40 and 70 and affected by laryngeal cancer underwent mucociliary clearance evaluation the day before total laryngectomy, 60 days after and, in 6 of them, 5 years later. Specimens of nasal and tracheal mucosa were obtained during laryngectomy and other subsequent operations. Before total laryngectomy, no significant changes in nasal mucociliary clearance were observed in smokers and controls, and the nasal ciliary carpet was fairly well preserved. Bronchial mucociliary clearance was impaired in all patients, owing to the coexistent chronic obstructive bronchitis. 60 days after the operation, nasal mucociliary clearance was significantly improved when compared with the preoperative data and controls, owing to the increase in the endonasal temperature and humidity, and to the reduction of the nasal blood flow and disappearance of the nasal cycle, which follow tracheostomy. Surface morphologic studies show a change in the squamous epithelium of the anterior third of the nasal fossa into a columnar ciliated one. During the first 3 months after the operation, tracheobronchial mucociliary clearance increased of 50% vis-à-vis the preoperative data. During this period a clinically evident bronchial hypersecretion was observed. The reduction in nasal and tracheobronchial mucociliary clearance function which became evident 6 years after the operation, is probably due to secondary chronic infections.

    ABSTRACT: It has been previously observed that patients with head and neck squamous cell carcinoma or with laryngeal leucoplakia present a significant reduction in plasma folate levels. The current Phase IIA pilot study assessed the effectiveness of folic acid as a chemopreventive agent in patients affected by glottic laryngeal leucoplakia. Forty-three untreated patients affected by glottic laryngeal leucoplakia were enrolled in the Ear, Nose, and Throat Department (Universita Cattolica del Saco Cuore, Rome, Italy). Glottic leucoplakia was initially diagnosed by indirect laryngoscopy and successively confirmed by diagnostic direct microlaryngoscopy with a biopsy for histologic assessment. Folic acid (Folina, Schwarz Pharma, Germany) was administered orally (5 mg every 8 hours) for 6 months. Patients were monitored every 30 days by videolaryngoscopy. Twelve (28%) patients had no response, 19 (44%) had a partial response, and 12 (28%) had a complete response. The mean increase in serum folate levels (10.06 +/- 0.53) and the mean decrease in homocysteine serum (3.65349 +/- 0.85526) at the end of the study were highly significant (P = .0001). The larynx is 1 of the sites of major interest and a good model for the development of chemopreventive agents, but so far the proposed agents have shown no clear efficacy on precancerous lesions or on the development of second malignancies.

    ABSTRACT: To analyze oncologic results in patients with glottic cancers treated respectively, by laser CO 2 or open surgery, taking into account specific-disease survival, rate of locoregional recurrences, and their salvageability. Retrospective study of 198 patients treated from January 1993 to June 2002 in the department of otorhinolaryngology at a Catholic university in Rome. Glottic carcinoma were treated by laser CO 2 cordectomy in 132 patients (group 1) and by open surgery in 66 patients (group 2). The statistical analysis was performed by Kaplan Meyer method, log rank test, and chi 2 test. The log-rank test points out significant differences between the 2 groups regarding specific-disease survival; no differences were found for disease-free survival. Within group 1, 16 patients developed local failure, which was retreated in 6 cases with laser surgery; in 9 (6.8%) with total laryngectomy, only 1 case was inoperable. In this group, 10 patients (62.5%) were salvaged. Within group 2, 18 patients developed local recurrences, which was retreated in 14 (21.21%) cases with total laryngectomy; the other 4 cases were not suitable for surgery. Of these 18, 8 patients (44.5%) were salvaged. Our results show significant differences between the 2 groups concerning the specific-disease survival and the salvageability of local recurrences. In fact, in group 1 we found a higher salvage rate and a lower incidence of total laryngectomy. As already suggested, laser therapy leaves the laryngeal cartilaginous framework intact, avoiding the spread of the tumor out of laryngeal organ and resulting in a more favorable oncologic outcome.

    ABSTRACT: Of the most frequent malignancies in the United States, cancers of the larynx and of the uterine corpus are the only ones not to show an increase in 5-year survival rates over the last 30 years. The increasing use of chemo- and radiotherapy and conservative surgery to preserve organs and their functions has probably led to a better quality of life in patients with laryngeal cancer, but has definitely failed to improve survival, which remains the primary aim. In our opinion, to reduce laryngeal cancer-related mortality, a change in clinical approach is required. We have reviewed the literature on the potential role of molecular markers in the clinical management of laryngeal cancer. We believe that some of the most significant biological markers might be integrated with the evaluation of behavioural risk factors, clinical TNM staging and histopathological grading for a novel clinicomolecular approach to laryngeal cancer. We foresee the use of the most promising biological markers in the phases of prevention, diagnosis, prognostic assessment and drug design.

    ABSTRACT: Head and neck cancer (HNSCC) includes squamous cell carcinomas of the oral cavity, pharynx and larynx. Approximately 38,500 cases of HNSCC are estimated to occur in the USA in 2004, with 11,000 deaths. HNSCCs represent about 3% of all malignant tumors in the USA. However, in other parts of the world, as India, Southeast Asia or Brazil, the disease is much more prevalent. The standard therapeutic approach, focused on surgery, irradiation and chemotherapy, alone or in combination, has been in part modified in the last 30 years, but the overall survival of HNSCC patients has not substantially improved. To characterize and thus identify high-risk mucosal areas and preclinical tumors, molecular abnormalities in head and neck carcinogenesis have been extensively studied. Metabolic aspects in head and neck carcinogenesis have been less extensively studied. Nevertheless, we know that metabolic alterations, often aspecific, are frequently associated with cancer. These may be secondary or may precede tumor development and favorite progression. In particular, based upon our results, a role for folate deficiency as a risk factor in head and neck carcinogenesis seems plausible. A chemoprevention protocol with folate is at present feasible and ethically correct and is already in progress at our institution. Homocysteine levels in cancer patients are probably largely affected by the HNSCC phenotype. An accumulation of homocysteine might reveal a genetic defect which is theoretically a target for pharmacological therapy, for example by antifolic drugs.

    ABSTRACT: In this study, we investigated whether vestibular evoked myogenic potentials (VEMPs) and dynamic posturography (DP) are useful in the evaluation of the vestibular function in patients affected by active monoaural Menière's disease (MD) treated with intratympanic gentamycin. Twelve subjects affected by monoaural MD were treated with weekly intratympanic injections of 0.5 ml of gentamycin at a concentration of 20 mg/ml. VEMPs were used to test saccular function, while postural control was analyzed by DP. The results obtained with these two techniques were compared with those obtained by using bithermal caloric test. The mean follow-up was 15.3 months (6--28 months). Therapy resulted in complete absence of the caloric response in six subjects (50) and in caloric test-induced asymmetry in the remaining individuals, ranging from 83 to 27. At follow-up, eleven patients (91.6%) were free of vertigo, while one patient had two vertigo spells 9 months after treatment. Before treatment, VEMPs were present in the affected ear of eleven patients. After treatment VEMPs were absent in all the patients. At the end of follow-up, reappearance of VEMPs was observed in two patients, with no changes in latency values and amplitude ratio. DP demonstrated a reduction of the Composite Score (CS) one week after therapy, with a prevalent reduction of the vestibular component. After 6 months, there was an improvement of the CS and, in particular, of the vestibular component. The present study demonstrates that bithermal caloric test and VEMPs allow for the functional evaluation of both the horizontal semicircular canal and the sacculus, suggesting that these techniques might be used together to monitor the efficacy of intratympanic gentamycin therapy. In addition, our data indicate that DP might provide important information on compensation phenomena and show that intratympanic gentamycin can improve postural control in MD patients.

    ABSTRACT: The authors evaluated serum levels of folate, homocysteine, and vitamin B(12) in patients with head and neck squamous cell carcinoma (HNSCC) and in patients with laryngeal leukoplakia, a well known preneoplastic lesion. One hundred forty-four consecutive, untreated patients with HNSCC and 40 consecutive, untreated patients with laryngeal leukoplakia were enrolled in the Department of Otolaryngology at the authors' institution. Data from those patients were compared with data from one control group, which included 90 smokers, and from another control group, which included 120 nonsmokers. Serum levels of homocysteine, folate, and vitamin B(12) were measured by an automated immunoassay method based on fluorescence polarization immunoassay technology. Comparing groups by Student-Newman-Keuls test, serum folate levels were significantly lower in patients with HNSCC and in patients with laryngeal leukoplakia compared with serum folate levels in both the smoker control group and the nonsmoker control group. Serum homocysteine levels in patients with HNSCC were significantly higher compared with homocysteine levels both in the smoker and nonsmoker control groups and in patients with laryngeal leukoplakia. There were no statistically significant differences between groups in serum vitamin B(12) levels. A role for folate deficiency as a risk factor in head and neck carcinogenesis is plausible. A chemoprevention protocol with folate is both feasible and ethically correct and is in progress at the authors' institution. Homocysteine levels in patients with HNSCC probably are affected largely by the HNSCC phenotype. An accumulation of homocysteine may reveal a genetic defect, which, theoretically, may be a target for pharmacologic therapy, for example, with antifolic drugs.

    ABSTRACT: To investigate the association between gastric surgery and cancer of the larynx. Biliary reflux is frequent after gastric surgery and may reach the proximal segment of the esophagus and the larynx. It is possible that duodenal content (consisting in bile acids, trypsin), together with pepsin and acid residues when gastric resection is partial, may cause harmful action on the multistratified epithelium of the larynx. A retrospective case-control study on subjects admitted between January 1987 and May 2002 in the same hospital in Rome was carried out. The study included 828 consecutive patients with laryngeal cancer (cases) and 825 controls with acute myocardial infarction. Controls were randomly sampled out of a total of 10,000 and matched with cases for age, sex, and year of admission. Logistic regression models were used to assess the role of gastric resection in determining laryngeal cancer risk while controlling for potential confounding factors. Previous gastrectomy was reported by 8.1% of cases and 1.8% of the controls (P < 0.0001). A 4-fold association emerged between gastric surgery and laryngeal cancer risk (adjusted OR = 4.3, 95% CI: 2.4-7.9). The risk appeared strongly increased 20 years after surgery (OR = 14.8, 95% CI: 3.4-64.6). Heavy alcohol drinking (OR = 2.5, 95% CI: 1.8-3.5), smoking (OR = 4.7, 95% CI: 3.3-6.7), and blue-collar occupation (OR = 4.6, 95% CI: 3.2-6.7) were all independently associated with the risk of laryngeal cancer. Previous gastric surgery is associated with an increased risk of laryngeal cancer. A periodic laryngeal examination should be considered in long-term follow-up of patients with gastric resection.

    ABSTRACT: In this paper, we try to briefly review the most recent knowledge on head and neck cancer, and especially multistep laryngeal carcinogenesis, and to simply explain how this has modified our understanding of field cancerisation phenomenon. Experimental studies, made possible by the recent evolution of microdissection systems, have demonstrated that the "spatial progression"of the histopathological phenotype in the surroundings of malignant or premalignant head and neck lesions correlates with molecular progression. Such a "spatial progression" can be hypothesised to reflect temporal progression. The field cancerisation process has been divided into three phases, each with its own histological and molecular characteristics. Each of these phases may have clinical implications: detection and monitoring of fields may help cancer prevention (molecular epidemiology), early detection of recurrence (or, more exactly, of second field tumours (SFTs)) (molecular diagnostics) and prognostic prediction after treatment. This model appears plausible, especially in explaining the development of multiple primary tumours (MPTs) in adjacent head and neck mucosal regions, with peculiar clinical and prognostic implications: These tumours can be defined as multiple field tumours (SFTs). However, the model, in our opinion, does not convincingly explain the development of second primary tumours (SPTs) at more distant sites, such as the lung, colon and prostate.

    ABSTRACT: A number of studies have shown that cisplatin and gentamicin ototoxic effects may result from free radical-mediated damage due to the reduction of antioxidant substances and an increased lipid peroxidation. The authors summarize the results obtained evaluating the auditory and vestibular functions and the inner ear hair cell morphology and survival after administration of antioxidant agents against cisplatin and gentamicin. In the first experiment, albino guinea pigs were treated with gentamicin (100 mg/kg per day, i.m.) alone or gentamicin (100 mg/kg per day, i.m.) plus alpha-tocopherol (100 mg/kg per day, i.m.) for 2 weeks. In a second experiment, albino guinea pigs were injected with cisplatin (2.5 mg/kg per day) or cisplatin (2.5 mg/kg per day) plus tiopronin (300 mg/kg) for 6 days. Electrocochleographic recordings were made from an implanted round window electrode. In all experiments compound action potentials (CAPs) were measured at 2-16 kHz. Changes in cochlear function were characterized as CAP threshold shifts. To evaluate vestibular function, the animals underwent sinusoidal oscillations in the dark about their vertical and longitudinal axes to evoke horizontal and vertical vestibulo-ocular reflexes (VOR). Frequency stimulation parameters ranged from 0.02 to 0.4 Hz and peak-to-peak amplitude was 20 degrees. Morphological changes were analysed by light microscopy and scanning electron microscopy. Both hearing loss and vestibular dysfunction induced by gentamicin were significantly attenuated by alpha-tocopherol. However, tiopronin co-therapy slowed the progression of hearing loss in cisplatin-treated animals and significantly attenuated the final threshold shifts. Cisplatin had little effect on the hair cells of cristae ampullares and maculae. Vestibular function was completely preserved in tiopronin co-treated animals. In conclusion, antioxidants such as alpha-tocopherol or tiopronin interfere with gentamicin and cisplatin damage and this suggests that they may be useful in preventing oto-vestibulotoxicity. Therefore, it is important to develop protective strategies that permit the avoidance of the toxic side effects of these drugs without interfering with their therapeutic effects.

    ABSTRACT: Human papillomavirus (HPV) infection is suspected to be a risk factor for head and neck, and in particular for laryngeal, carcinogenesis. Cyclin D1 gene (CCND1) overexpression and amplification have been shown to play a role as prognostic factors in many human cancers, among which are head and neck cancers. A literature review of the role in head and neck cancers of HPV infection and CCND1 overexpression and amplification was undertaken. We have evaluated the extent of the current knowledge in this field under the light of recent acquisitions, in particular, about a correlation between HPV infection, a suspected risk factor, and CCND1 amplification, a frequent mutation (about 20% of laryngeal cancers) and a prognostic factor in laryngeal SCC. The significant correlation between HPV infection and CCND1 amplification supports the hypothesis of the involvement of HPV infection in laryngeal carcinogenesis and suggests that HPV positive laryngeal cancers may constitute a different subset of tumors with a peculiar molecular pattern and thus with a different clinical behavior. HPV infection may be considered a synergistic risk factor with smoking and/or alcohol consumption to be investigated in heavy smokers and drinkers, thus contributing to the identification of patient at high-risk for the development of laryngeal cancer who should undergo strict follow-up and primary and secondary prevention.

    ABSTRACT: This study was designed to add new data about laryngeal carcinogenesis, a multistep process in which chemical and/or viral agents induce and promote successive alterations in growth factor-linked signal transmission pathways, genetic instability, and mutations in key genes involved in cell growth control. Epidemiological evidence suggests that human papillomavirus (HPV) infection may be associated with the development of laryngeal cancer. In this report, we have analyzed the prevalence of HPV infection and epidermal growth factor receptor (EGFR) expression in a series of 42 laryngeal squamous cell carcinomas by PCR with HPV consensus primers and by a radioligand receptor assay, respectively. HPV DNA was detected in 15 of 42 (35.7%) tumors, and it belonged almost exclusively to the highly oncogenic HPV-16, HPV-18, and HPV-33 genotypes. At analysis by Mann-Whitney nonparametric statistical test, EGFR level was found to be significantly higher in HPV-infected than in HPV-negative cases (T = 440; P = 0.002). EGFR overexpression (EGFR-positive status >6 fmol/mg protein, the arbitrary cutoff value chosen) was found in 20 of 42 (47.6%) tumors, and it was associated with HPV infection in a statistically significant extent (chi(2) = 4.686; P = 0.03). Viral oncoproteins have been shown to induce a perturbation of the cell response to signals for growth and differentiation; these findings confirm that enhanced EGFR expression and activation in laryngeal squamous cell carcinoma may occur also as a consequence of HPV infection and support the hypothesis of an involvement of HPV infection in laryngeal carcinogenesis.

    ABSTRACT: It is still debatable whether anxiety and depression in patients affected by rhinitis could play a role in the genesis of the disease, whether they are a consequence of the symptoms. The aim of this study was to evaluate anxiety levels in both state and trait forms, and depression, in patients affected by allergic (AR) and vasomotor rhinitis (VMR). A total of 45 women, 24 AR and 21 VMR were compared with 64 healthy nonallergic women matched for age and sociodemographic characteristics. All subjects were administered the State and Trait Anxiety Inventory (STAI) and the Zung self-rating depression scale. The percentage of subjects with high levels of state anxiety was significantly higher in AR (p<0.005) and VMR (p<0.01) with respect to controls. The percentage of subjects with high levels of trait anxiety was significantly higher in AR (p<0.001) and VMR (p<0.05) than controls. There was no significant difference in depression between AR and VMR and controls. No significant difference was found in state anxiety, trait anxiety, or depression between AR and VMR. In conclusion, anxiety in patients with rhinitis is present both as a state and as a trait, at least when measured with the STAI.

    ABSTRACT: A total of 39 patients with bilateral post-thyroidectomy vocal cord paralysis in adduction underwent CO2 laser subtotal arytenoidectomies with removal of the posterior third of the false and true vocal cords. Total airway resistance (Rtot) evaluated before and 4-10 months after surgery showed marked preoperative impairment before and significant improvement after surgery (P < 0.05). In five patients revision surgery was performed due to a progressive impairment of respiratory function. A variable degree of voice breathiness was observed after surgery; the maximum phonation time mean values were lower than normal and peak sound pressure levels 63 +/- 5 dB. In three cases aspiration was present in the first postoperative days, but swallowing dysfunctions disappeared within 1 week. Subtotal arytenoidectomy with removal of the posterior third of the true and false vocal folds was found to be a satisfactory surgical treatment for bilateral vocal cord paralysis in adduction. However, further research is still needed to define the surgical procedure able to balance respiratory, phonatory and sphincteric functions optimally.

    ABSTRACT: The aim of this study was to verify the oncological and functional outcome of conservative surgical treatment of primary supraglottic squamous cell carcinoma (SGSCC) and related neck disease in order to verify the effectiveness of supraglottic laryngectomy (SL) and the validity of an "observation" policy in the control of clinically negative (N0) necks. Of a total of 252 consecutive patients affected by primary SGSCC seen between 1975 and 1990 at the Department of Otolaryngology of the University of Perugia (1975-1987) and the Catholic University of the Sacred Heart of Rome (1988-1990), a subset of 132 patients treated with classical SL was evaluated after presenting sufficient clinicopathological data and a follow-up period of at least 5 years. Tumors were staged according to the 1992 UICC TNM classification and grouped into stages I-II (n = 94) and III-IV (n = 38). Comprehensive neck dissections were performed only in the clinically positive (N+) necks (25/132 cases), while in the clinically N0 ones (107/132 cases) an "observation" policy under strict follow-up conditions was adopted. After primary surgery, the 5-year relapse-free survival (RFS) was 74%. The RFS was 80% for T1-2 disease and 65% for T3. The RFS was 80% for stages I-II tumors and 71% for stages III-IV. The actual 5-year overall survival (OS) was 89% for T1-T2 tumors and 67% for T3 disease or 93% for stage I-II and 69% for stages III-IV. The OS was 89% for N0 neck and 73% for N+. The 5-year-metastasis-free survival (MFS) was 83% for N0 patients, 74% for N+, 84% for T1-T2 N0, 71% for T1-T2 N+, 81% for T3 N0 and 68% for T3 N+. In all, SL was found to be highly effective in the management of primary SGSCC. In the presence of clinically N0 neck "observation" under strict follow-up with therapeutic comprehensive neck dissection for delayed nodal recurrence, SL was suitable for controlling the neck cancer, as well as for salvaging recurrent disease. Bilateral elective, selective or functional neck dissection in every instance of supraglottic cancer was best performed only in those SGSCC patients who were more likely to have occult nodal disease on the basis of biological factors and imaging data.
