Most of them are chondromas and they often involve to the cricoid cartilage. A 31-year-old male patient applied to the oto-laryngology service with a history of dysphonia and dyspnea. Microlaryngoscopy revealed 2 cm sized, ill-defined, covered with regular mucosa, porous, and hard mass on posterior surface of crycoid cartilage in subglottic area. Following the excision of the lesion, histopathologic examination revealed as chondroma. Two years later, local recurrence was detected and the diagnosis was again chondroma. There was no complaint of the patient in last 3 and half years of follow-up. Chondroma should carefully be differentiated from chondrosarcoma and the patients should be followed for possible recurrences.

Dermoid cysts of the head neck are uncommon and account for only 7% of all such cysts. They are most often reported as arising in the floor of the mouth. Dermoid cyst is rarely seen in the parotid gland. To our knowledge, there have been only six previous case reports in the English literature. Dermoid cyst of the parotid gland in pediatric patient has not been previously reported in the literature. This is the first case report concerning a dermoid cyst in a pediatric patient.

[show abstract][hide abstract] ABSTRACT: Malignant melanoma is a highly unpredictable tumor that has capacity to metastasize to any organ. A better understanding is needed of the clinicopathologic features of metastatic melanoma and, in particular, of its rare manifestations.
A 33-year-old woman with a past medical history of malignant melanoma presented with symptoms of throat discomfort and bleeding. On physical examination, a dark pigmented lesion was observed on the right tonsil. Tonsillectomy was performed, and melanoma was diagnosed. Computed tomography of the thorax and abdomen revealed a filling defect in the right atrium and a 4-cm gallbladder mass. Echocardiography revealed a right atrial mass. No further metastasis was detected by whole body (18)F-fluorodeoxyglucose positron emission tomography. Each metastasis was completely resected with clear margins. The pathologic diagnosis of the resected masses was malignant melanoma. 3 weeks after the final surgery, temozolomide was started. The patient has been followed up for 9 months after diagnosis of the first recurrence, and no new metastases have been detected.
We report a case with synchronous tonsil, gallbladder, and heart metastases without any other common sites of metastasis of melanoma. The patient was successfully treated with aggressive surgery followed by temozolomide.
[show abstract][hide abstract] ABSTRACT: Thyroglossal duct cyst is the most common midline congenital neck anomaly. Carcinoma arising from a thyroglossal duct cyst is a rare entity, the most common histological type being papillary carcinoma. A 23-year-old male patient presented with a painless mass at the level of the hyoid bone in the midline of the neck. It was mobile on swallowing. With an initial diagnosis of thyroglossal duct cyst, the lesion was removed with the Sistrunk procedure. Histopathological examination of the surgical specimen showed papillary carcinoma arising from the thyroglossal duct cyst. Thyroid suppression therapy was initiated postoperatively. The patient has been under follow-up for 30 months with no recurrence.

[show abstract][hide abstract] ABSTRACT: Assessment of auditory abilities is important in the diagnosis and treatment of children with autism. The aim was to evaluate hearing objectively by using transient evoked otoacoustic emission (TEOAE) and auditory brainstem response (ABR). Tests were performed on 30 children with autism and 15 typically developing children, following otomicroscopy and tympanometry. The children with autism were sedated before the tests. Positive emissions and normal hearing level at ABR were obtained in both ears of all children in the control group and of 25 children with autism. TEOAE and ABR results varied in the remaining five children with autism. The mean III-V interpeak latencies (IPLs) in both ears of children with autism were longer than those in the control group. Hearing loss may be more common in children with autism than in typically developing children.
[show abstract][hide abstract] ABSTRACT: We evaluated psychological symptoms of patients who underwent partial or total laryngectomy for larynx cancer.
The study included 63 patients who underwent total (n=41) or partial (n=22) laryngectomy. The control group consisted of 20 healthy individuals with similar gender, age, and sociocultural characteristics. During the postoperative follow-up, the psychological symptom distribution of the patients was assessed with the Symptom Check-List-90-Revised (SCL-90-R).
The SCL-90-R inventory was administered at a mean of 20.6 months (range 10 to 86 months) postoperatively. Patients with total laryngectomy had significantly higher scores than the controls in the subscales of interpersonal sensitivity, depression, anger-hostility, phobic anxiety, and global symptom index (p<0.05). Partial laryngectomy patients exhibited lower scores than total laryngectomy patients, and higher scores than the control group. The only significant difference between partial laryngectomy patients and the control group was in the subscale of anger-hostility (p<0.05).
Patients with laryngeal cancer should be given postoperative psychological support to minimize adverse effects of total or partial laryngectomy.

[show abstract][hide abstract] ABSTRACT: The aim of this study was to investigate otoacoustic emissions in young adults who had a history of otitis media (OM) in childhood and to assess whether a history of OM had an irreversible effect on hearing. We studied 116 cases between 15 and 25 years of age, divided into three groups. Each subject underwent a single examination comprising otoscopy, pure-tone audiometry (PTA), tympanometry, and transient evoked otoacoustic emission (TEOAE) and distortion product otoacoustic emission (DPOAE) testing. Subjects in the first and second groups had normal audiometric hearing thresholds and type A tympanograms. The only difference between the first and second group was the presence or absence of a history of OM. The third group consisted of patients diagnosed as having active OM; these patients had poorer hearing thresholds and type B or C tympanograms. After statistical analysis of TEOAE and DPOAE results (one-way analysis of variance test), significant differences were noted between groups. Otoacoustic emission levels were, unsurprisingly, lowest in the third group, as expected. However, the most striking result in the study was that significantly fewer otoacoustic emissions were detected in subjects with a history of OM than in subjects without a history of OM. These findings suggest that OM in childhood may cause minor but irreversible damage to the middle ear or cochlea. Otoacoustic emissions testing can be used to detect this sub-clinical damage.

[show abstract][hide abstract] ABSTRACT: We investigated the beneficial effect of magnesium in the prevention of noise-induced cochlear damage in guinea pigs by transient evoked otoacoustic emissions (TEOAE).
Thirty-nine guinea pigs with normal auropalpebral reflex were randomly divided into control (n=20) and study (n=19) groups. All the animals were subjected to wide-band noise standardized at a mean of 98+/-2 dB for 16 hours a day for 10 days in a sound isolated cabin. The study animals received 39 mmol/l MgCl2 throughout the study period starting from 15 days before noise exposure. Otomicroscopic examination, auditory brain stem response (ABR) and TEOAE measurements were performed before and after noise exposure. Tympanometric measurements were performed to eliminate possible middle ear pathologies.
Although the mean TEOAE response and reproducibility values showed significant decreases after noise application in the control group (p<0.001), they were not affected significantly in magnesium-treated animals. Post-exposure mean TEOAE response and reproducibility values significantly differed between the two groups (p<0.001). Noise-induced elevations in ABR thresholds were significant in both groups (p<0.001); however, it was noted that hearing levels were better preserved in the study group.
Our data suggest that oral magnesium intake may be beneficial in the prevention of cochlear damage in noise-induced hearing loss.

[show abstract][hide abstract] ABSTRACT: This aim of this study was to determine the effect of anaesthetic agents on stapedius reflex (SR) thresholds and transient evoked otoacoustic emissions (TEOAE). Fifty patients who were scheduled for operation and who had normal hearing were included in the study. All were given midazolam for premedication and propofol for induction. Anaesthesia was maintained in five different ways in each group of 10 patients. Groups I-IV received inhalational anaesthesia: group I received 70 per cent N2O plus 30 per cent O2, group II sevoflurane, group III desflurane and group IV halothane. Group V received total intravenous anaesthesia with propofol plus sufentanil. The SR and TEOAE of the patients were measured four times: on the day before surgery (first measurement), after premedication (second measurement), after induction of anaesthesia (third measurement) and during maintenance of anaesthesia (fourth measurement). Midazolam significantly increased ipsilateral and contralateral SR thresholds and decreased TEOAE wave reproducibility. Propofol significantly increased only the SR thresholds. The other anaesthetic agents significantly increased only the contralateral reflex thresholds. Of these, the highest increase was seen after sevoflurane and the lowest after halothane. The changes in TEOAE wave reproducibility due to anaesthetic agents used for maintenance were not significant. We concluded that midazolam premedication may affect audiological evaluation with SR and TEOAE tests, and sevoflurane should not be used when it is necessary to measure SR under general anaesthesia.

[show abstract][hide abstract] ABSTRACT: We evaluated the utility of transcranial Doppler ultrasonography in determining the vascular pathology in patients with sudden hearing loss.
The study included 13 patients (11 males, 2 females; mean age 46.6+/-17.7 years; range 18 to 66 years) with a diagnosis of sudden hearing loss. Patients having chronic otitis media or other middle ear diseases or a history of surgery in the affected ear were excluded. All the patients were evaluated by pure-tone audiometry, impedance audiometry, transient evoked otoacoustic emissions, auditory brainstem responses, and transcranial Doppler ultrasonography. The results were compared with those of a control group of 19 age- and sex-matched healthy subjects (12 males, 7 females; mean age 46.8+/-6.9 years; range 33 to 58 years) who did not have any ear disease or a history of ototoxic drug intake or working in a noisy environment, and no pathology on otoscopic and audiometric examinations.
Compared to the normal ear, the mean blood flow and systolic flow velocities of the vertebral artery were significantly decreased, and the mean pulsatile index was significantly increased on the affected side. The mean flow velocity of the basilar artery in the patient group was lower than that found in the control group.
Transcranial Doppler ultrasonography can be used for the evaluation of vascular involvement of the vertebral and basilar arteries in patients with sudden sensorineural hearing loss.

[show abstract][hide abstract] ABSTRACT: The combined Heermann and Tos (CHAT) technique is the combination of Heermann's 'cartilage palisade tympanoplasty' and Tos's 'modified combined approach tympanoplasty = modified intact canal wall mastoidectomy'. The first author (Cem Uzun) performed the CHAT technique as a one-stage operation in 15 ears of 15 patients with cholesteatoma. Two patients (one with a follow up of less than six months and one who did not show up at the final re-evaluation) were excluded from the study. Median age in the remaining 13 patients was 37 years (range: 14-57 years). Cholesteatoma type was attic, sinus (Tos tensa type 1) and tensa retraction (Tos tensa type 2) in six, five and two ears, respectively. Cholesteatoma stage was Saleh and Mills stage 1, 2, 3, 4 and 5 in one, three, four, four and one ear, respectively. The eustachian tube was not involved with cholesteatoma in any ear. After drilling of the superoposterior bony annulus, transcanal atticotomy with preservation of thin bridge and cortical mastoidectomy with intact canal wall, the cholesteatoma was removed, and the eardrum and atticotomy were reconstructed with palisades of auricular cartilage. Type I tympanoplasty was performed in two ears, type II in nine ears and type III (stapes absent) in two ears, with either autologous incus (eight cases), cortical bone (two) or auricular cartilage (one). No complication occurred before, during or after surgery. Oto-microscopy and audiometry were done before and at a median of 13 months after surgery (mean 14 months, range 7-30 months). There was no sign of residual or recurrent cholesteatoma in any patient during the follow-up period. At the final examination, all ears were dry and had an intact eardrum except one with a small, central hole, which had been seen since the early post-operative period. Clean and stable attic retraction with a wide access was observed in two ears. Post-operative hearing at the final evaluation was better (change > 10 dB) than the pre-operative one in nine ears and did not change in the remaining four. Pre- and post-operative mean hearing values were, pure-tone average 47 and 35 dB (p = 0.01) and air-bone gap 30 and 20 dB (p = 0.02), respectively. With the CHAT technique, cholesteatoma can be completely and safely removed from the middle ear, and a durable and resistant reconstruction of the middle ear with reasonable hearing can be achieved. However, a further study should analyse long-term results of a larger patient group.

[show abstract][hide abstract] ABSTRACT: We aimed to investigate, histopathologic changes in the nasal mucosa of guinea pig's after prolonged administration of oxymetazoline and the development of rhinitis medicamentosa, and the efficacy of mometasone furoate aqueous nasal spray and saline in reversing the ultrastructural changes attributable to rhinitis medicamentosa.
In the study, 24 male guinea pigs (500 to 600 gr) were used. Oxymetazolin (0.05%) was sprayed into the nasal cavities of the guinea pigs 3 times daily for 8 weeks. At the end of this period, 6 guinea pigs were killed and examined to make sure that the animals had developed rhinitis medicamentosa. The remaining guinea pigs were randomly divided into 3 groups. In the first group, one spray-puff of 0.05% mometasone furoate aqueous nasal spray (50 microg) was applied twice daily for 14 days. In the second group, saline solution (0.9% NaCl) was applied twice daily for 14 days. No treatment was performed in the third group. At the end of the treatment period, nasal mucosal changes were evaluated by light microscopy and electron microscopy.
After oxymetazolin application for 8 weeks, the main histologic changes were edema, congestion, proliferation of subepithelial glands, and squamous cell metaplasia. After topical mometasone furoate aqueous spray application for 2 weeks, the edema fluid was found to diminish markedly. In the saline and no treatment groups, edema and congestion continued. In these groups of guinea pigs, fibrosis has been seen in the nasal mucosa.
We found that mometasone furoate nasal spray was effective against experimentally induced rhinitis medicamentosa in guinea pigs. Mometasone furoate nasal spray may have value in the treatment of patients with rhinitis medicamentosa.

[show abstract][hide abstract] ABSTRACT: We investigated the value of assessing the degree of mastoid pneumatization in predicting middle ear barotrauma -the most common problem in sport SCUBA divers- in comparison with that of the conventional pre-dive examination method, the Valsalva maneuver.
Thirty-four volunteer sport SCUBA divers having normal pre-dive examination findings were included. The Valsalva test was performed in all the divers. Mastoid pneumatization for each ear was calculated on a Schuller's view radiography. Pneumatization of = or <30 cm2 was accepted as poor (prone to barotrauma) and >30 cm2 was accepted as good (not prone to barotrauma). During the observation period, the divers were monitored with regard to barotrauma symptoms and signs.
The degree of mastoid pneumatization was = or <30 cm2 in 26 ears (38%) of 16 divers (47%). The Valsalva test was negative in eight ears (12%) of six divers (18%). During a total of 1001 dives, symptomatic middle ear barotrauma occurred in 28 dives (2.8%), i.e. in 21 ears (31%) of 16 divers (47%). Of these, the degree of mastoid pneumatization predicted barotrauma in 11 (69%) divers, whereas the Valsalva test was negative in only three (19%) (p<0.05), with sensitivity, specificity, positive and negative predictive values, and efficiency being 69% and 19%, 72% and 83%, 69% and 50%, 72% and 54%, and 71% and 53%, respectively.
The value of assessing mastoid pneumatization in predicting middle ear barotrauma in sport SCUBA divers is higher than that of the Valsalva test.

[show abstract][hide abstract] ABSTRACT: Sixty-eight patients who presented with glottic and glottosupraglottic squamous cell carcinoma and who were managed in this department with supracricoid partial laryngectomy (SCPL) with either cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP), were retrospectively reviewed. The authors analysed the functional and oncological results of the patients. The median follow-up period was 62 months. The average times until decannulation and nasogastric feeding tube removal were 27.7 and 26.4 days, respectively. All patients were successfully decannulated. All patients were able to swallow, but one patient was unable to swallow and had recurrent aspiration. Better functional results were achieved in patients managed with CHEP procedure than the patients managed with CHP procedure. The five-year absolute and cause-specific actuarial survival rates (Kaplan-Meier method) were 78.6 per cent and 93.9 per cent, respectively. The five-year actuarial local control and nodal control rates were 89.5 per cent and 90.4 per cent, respectively. Local recurrence was statistically more likely in patients with positive resection margins (p <0.006). Overall, local control and laryngeal preservation were achieved in 95.6 per cent and 89.7 per cent, respectively. Supracricoid partial laryngectomy procedures (CHEP and CHP) are possible alternatives to total laryngectomy in the treatment of selected advanced glottic and glottosupraglottic carcinomas.

[show abstract][hide abstract] ABSTRACT: It is well documented that children, particularly between the ages of about 2 and 6 years, exhibit a high prevalence and incidence of otitis media. Distortion product otoacoustic emissions (DPOAEs) offer great potential for clinical testing of cochlear function in children. The aim of the present study was to determine the influence of middle ear effusion and physical properties of the effusion on the recording of DPOAE.
Nineteen children (38 ears) undergoing myringotomy and/or tympanostomy tube insertion for secretory otitis media were studied. Pre-operative and post-operative first day DPOAE signal to noise ratios were compared. The results were analyzed by paired samples test and ANOVA statistical methods.
We were found significant differences between pre-operative and post-operative first day DPOAE signal to noise at 1, 1.5, 2 and 4kHz. In addition, comparison of the pre-operative DPOAE signal to noise ratio and per-operative middle ear findings are shown significant differences between glue (thick mucous) and the other three groups (mucous, serous and no-effusion groups) at 2 and 4kHz, and between glue and no effusion group at 8kHz. Also post-operative DPOAE signal to noise ratio in relation to per-operative middle ear findings were significantly different at 2, 4 and 8kHz. The most increase of emissions at the post-operative first day was seen in ears with glue effusion at 1 and 2kHz.
Otitis media with effusion can be monitored by DPOAE measurement pre-operatively and post-operatively. In the pre-operative evaluation, glue effusion may cause a reduction in the emissions at 2, 4 and 8kHz more than the other kind effusions.

[show abstract][hide abstract] ABSTRACT: To evaluate quality of life of patients undergoing surgical treatment for larynx cancer and to compare quality of life between patients with total laryngectomy and partial laryngectomy.
Thirty-two questions were asked to patients who underwent total laryngectomy (22 subjects) or partial laryngectomy (24 subjects). These questions were based on the European Organization for Research on Treatment of Cancer questionnaires Quality of Life--C30 (EORTC-QoL-C30) and adapted to our nation. Patients with total laryngectomy and partial laryngectomy were compared according to the answers.
We found significant statistical differences between total and partial laryngectomy patients in 12 questions. When functional disorders were evaluated, the most significant was one associated with communication. However, pain, smell disorders and increased secretion were associated with morbidity that resulted from the type of surgery. It was observed that patients with total laryngectomy were particularly affected psychologically and economically.
Patients subjected to total laryngectomy experience serious physical and psycho-social disadvantages that arise from the treatment. In order to establish these negative effects and to minimize them, tools of assessment of quality of life should be developed. This assessment should be appropriate for our nation, providing information and psychological support for individuals and their families.

[show abstract][hide abstract] ABSTRACT: We investigated the eustachian tube function and the incidence of alternobaric vertigo (AV) in 29 sport self-contained underwater breathing apparatus (SCUBA) divers with, or without, some possible risk factors for AV. The divers had normal audiological and otoscopic findings at the pre-dive examination. We used the nine-step inflation/deflation tympanometric test and Toynbee test for evaluation of eustachian tube function, and the Valsalva manoeuvre for patency. Information on divers, their history, and their otolaryngologic examination were obtained in the pre-dive examination. Divers performed 1086 dives (mean 37, range: 3-100) during the observation period. Four divers (14 per cent) experienced AV during five dives (0.46 per cent), (one diver experienced AV two times). It was found that having an otitis media history or eustachian tube dysfunction determined with the nine-step inflation/deflation tympanometric test before diving, or difficulty in clearing ears during diving could be important risk factors for AV in sport SCUBA divers (p <.05). Divers with such findings seem to be more prone to AV and should pay rigorous attention to the precautions for prevention of AV.

[show abstract][hide abstract] ABSTRACT: The possible cochlear toxicity of topically applied povidone-iodine solution was investigated in guinea pigs by measuring transiently evoked otoacoustic emissions (TEOAEs). Seven adult pigmented guinea pigs (14 ears) with a normal acoustic pinna reflex were used. After the baseline TEOAE measurements, 0.1 mL of povidone-iodine solution was applied transtympanically into the middle ear in the study group. Saline solution and gentamicin were used as negative and positive control, respectively. TEOAE measurements were repeated on the 10th day, and four weeks after the first application. Tympanometric measurements were also carried out for both ears of all animals at the end of the study. Responses in all ears, which had povidone-iodine applied to them, disappeared in a way similar to those recorded in gentamicin-treated ears. Tympanometric measurements at the end of the study showed 'type A' tympanograms in all ears of all animals. The present study showed that povidone-iodine could have a cochleotoxic effect in guinea pigs. A study in humans with TEOAE before and after middle-ear surgery, where povidone-iodine can reach into the middle-ear cavity, may be useful for evaluating this result for clinical practice.
