    ABSTRACT: Extensive primary and recurrences tumors in the head and neck region require salvage surgery procedure. It involves the removal of large neoplastic lesions and supplying local defects. The purpose of reconstructive surgery is to achieve maximal functionality and aesthetics results of reconstructed organ. Anterolateral free thigh flap is the most common flap used in reconstructive surgery. The possibility of using anterolateral thigh flap including indications, contraindications and the risk occurrence of local complications was presented upon the latest reports available in the literature and our own experience.

    ABSTRACT: The aim of this study was to analyze two cases with advance tumors of the neck with infiltration of the common or internal carotid artery. Patients were surgically treated in Department of Otolaryngology Poznan University of Medical Sciences. Authors present the current state of knowledge concerning the proceedings in unresectable tumors of the neck and possibility to use the salvage surgery. Based on literature data and our own experience a risk of the carotid artery infiltrations is difficult to assay in diagnostic procedure. It decrease the possibility of radical surgery resection and indicate the most advance stage. Choosing the proper treatment requires interdisciplinary cooperation: ENT specialist, radiologist, vascular surgeon and oncologist. The high rate of complications and local recurrence rate makes the results of treatment are unsatisfactory.

    ABSTRACT: Objective Evaluation the outcome after extensive surgery of salivary glands tumors with simultaneous reconstruction of soft tissue and skin defect.MaterialIn the period 2007–2011, surgery treatments performed in 295 of major salivary glands. 31 patients underwent surgery due to malignant parotid gland tumors: 19 women (61%) and 12 men (39%). In 8 (26%) presented skin infiltration. 10 (32%) patients had facial palsy between II-IV degree (House Brackmann scale). The radiographic findings in some patients showed infiltration of the deep lobe of parotid gland, external auditory canal, infiltration of mastoid process, skull base and the subtemporal fossa.Methods Of the 31 patients in 13 (42%) reconstruction techniques with muscle cutaneous trapezius flap were applied in 4 (31%) patients. In group of 7 (54%) patients using a muscle flap based on the sterno-cleido-gland, in 2 (15%) patients defects were covered using the free anterior lateral thigh flap.ResultsIn all patients, healing proceeded normally. In the operated patients, one patient did not receive radical surgery due to the infiltration of the skull base. Length of hospitalization ranged between 7–21 days. In no case was lost flap, also there was no local complications at the donor.Conclusions The choice of treatment for malignant parotid gland tumors which are usually radioresistant is surgical resection. In patients with extensive tumors with infiltration of neighbouring organs reconstruction with use of distant flaps are recommended. It provides a good oncological and aesthetic result.

    ABSTRACT: The main aim of this article is the epidemiological analysis of patients treated due to oral and oropharyngeal cancer, with a special interest in the group under the age of 40, evaluation of the differences in the clinical course of the disease as well as assessment of the treatment results, regarding the age of the affected individuals. 523 individuals affected by oral and oropharyngeal cancer who were treated in the Otolaryngology and Laryngeal Oncology Department between 2000 and 2008. Precise analysis was performed on 360 out of 523 affected individuals, in whom full clinical status was determined; 13 patients were young adults. The retrospective analysis was created based on case histories, surgical protocols and emergency records. In young adults there is a markedly increased risk of organ involvement according to the Mann-Whitney U-test analysis (p = 0.044907). The probability of recurrence in the group of young adults is also much higher. Analysis of Kaplan-Meier test results indicated that the chance for the lack of recurrence within a 6-month period was 85.7%; however, the risk of recurrence increased, and after 12 months was equal to the arithmetic data (50%). Among young adults there is an increased risk of local recurrence following 12 months after surgical intervention. According to our observations, despite rapid progression and early recurrence in young adults (4/7) the prognosis for both groups is not statistically different.

    ABSTRACT: PurposeEvaluation of the donor site efficiency in patients after reconstructive surgery with use of free forearm flap. All patients were treated for oral cavity and larynx cancer.Materials and methodsa group of 21 patients (16 men and 5 women) treated in 2007–2011. The retrospective analysis was conducted on the anamnesis, operating protocols, physical examination and a questionnaire, there was completed by patients during a routine ENT follow up examination. The PRWE (Patient Rated Wrist Evaulation) subjective questionnaire was used to estimate the rate of pain severity and wrist mobility.ResultsIn 59% of patients the wrist was healed primary, in 36% of patients by granulation. In all patients the wound was healed satisfactory in follow up examination, but 60% of patients revealed extensive scars formation. 62% of patients showed no local pain at rest, while in 38% of them worsening of symptoms was noticed – average 0.5/10 (median 1.0). Pain was more intense in patients who did basic motor activity of hands approximately 1/10 and lifting weights averaging 2.1/10. Dysfunction of the wrist was at the level of the average value of 4.2/50.Conclusions Surgical reconstruction with a use of the free forearm flap is associated with the formation of extensive wrist scars. The risk of local complications is low while preserving the qualification protocol, postoperative care and proper surgical management. Reconstructive surgery based on the free forearm flaps gives satisfactory functional results of the donor site. However, it requires surgical experience and practical knowledge of anatomy.

    ABSTRACT: Introduction The buccal flaps are an effective alternative in treatment patients with small defects of the oral cavity due to: the small size of the flap, the lack of donor site, less risk of postoperative complications and short procedure time. Material and methods In the Department of Otolaryngology and Laryngological Oncology in Poznan in the years 2005–2008 were performed 7 resections of oral cavity due to cancer in which the reconstructions were based on two types of flaps: from the buccal mucosa (3 patients), and muscular-buccal mucosal flap (4 cases). The paper presents aspects of the anatomical structure of the cheek and technique for flap dissection. Results and conclusions In the majority group of patients the primary defect healing properly. The mucosal buccal flaps are a good alternative to free flaps, but their indications are limited to the primary defects of small extent.

    ABSTRACT: Malignant fibrous histiocytomas (MFH) of the upper respiratory tract are rare, aggressive mesenchymal neoplasms. Ultrastructurally MFH consisted of five different types of cells. It occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. There have been sporadic laryngeal cases reported in the literature. We report a case of a glottic malignant fibrous histiocytoma on a 45 year old man. There was difficulty to find finally diagnosis. Pathologic and immunohistochemical evaluation revealed tumor a few months after first symptoms. There was unilateral metastases into the neck lymph nodes. Immunohistochemical staining was positive for F13a, CD68 and negative for desmin and cytokeratin. Wide, aggressive excision of the tumour with total larygectomy to be the treatment of choice because it was difficult to prove clinically and pathologically that it was MFH. Unilateral neck dissection was done due to metastases into the neck lymph nodes. Radiation have been used after surgery. About two years after total laryngectomy the patient is well and free of disease.

    ABSTRACT: Laryngeal cancer in Poland is characterized by high levels of morbidity and mortality. The main risk factors for the larynx cancer are alcohol drinking and tobacco smoking. In contrary to well established tobacco-related evidence for an increased risk of larynx cancer, alcohol-related mechanisms of carcinogenesis remain unknown. Nevertheless the effect of alcohol is modulated by polymorphisms in genes encoding enzymes for ethanol metabolism. Hence we investigated the ADH1C *1 genotype and allele frequency in a group of 102 larynx cancer patients with heavy alcohol consumption recruited from the Department of Otolaryngology and Laryngological Oncology of the University of Medical Sciences in Poznan. The data were compared with 112 non-cancer age-matched individuals consuming similar amounts of ethanol. Blood samples were used for analysis of restriction fragment length polymorphism. DNA was isolated from the whole blood leucocytes and PCR with specific primers was used to amplify polymorphic region of rs698 in the ADH1C gene. The method was based on allele detection by Sspl restriction enzyme digestion and after the incubation with enzyme, samples run on an electrophoresis. The statistic analysis was performed to calculate Odds Ratio (ORs), 95% confidence intervals (CIs) and significance. Results suggest a slightly increased risk of larynx cancer for individuals who have inherited the ADH1C *1 allele (rs 698), however they did not reach the level of statistic significance.

    ABSTRACT: Neurinoma is the most common tumor of the neurogenic origin. Primary location in the neck with the vagal nerve as a source is very rare clinical situation (less than 100 cases published in the literature). The authors would like to present a case of 35 old men with vagal neurinoma. Main symptoms included painless neck tumor found on palpation. Differential diagnosis included the pedicled cyst and metastatic neck mass. The ultrasound picture was unclear. The intraoperative findings suggested the tumor arising from the vagal nerve. In first day after the surgery hoarseness appeared with paresis of the right vocal cord in the examination. The final histological evaluation revealed neurinoma.
