[Stomal recurrence after total laryngectomy].

UNLABELLED: Stomal recurrence after total laryngectomy is a very serious complication, in general with dismal prognosis. There are only a few possibilities of treatment, so stress should be put on prevention. MATERIAL: In the ENT Department Poznań University of Medical Sciences between 1997-2004 829 total laryngectomy were performed, because of advanced laryngeal cancer (T3, T4). In this group until may 2005 37 cases of stomal recurrence were found. AIM: The aim of this study was to analyse the group of patients stomal recurrence. RESULTS: Stomal reccurence developed in 35 men and 2 women. The age of patients was 43-79 years (mean 59 years). The time of lasting the symptoms before laryngectomy was 6-12 months (mean 8 months). The emergency tracheotomy was performed in 16 patients (43%). The time between tracheotomy and laryngectomy was 2 days to 3 weeks (mean 6 days). The subglottic extension was observed in 24 patients (65%). 19 patients (51%) was classified as T3, 18 (49%) as T4. 12 patients (32%) was classified as N0, 5 (14%) as N1, 16 (43%) as N2 and 4 (11%) as N3. 4 patients were earlier treated because of larynx cancer (2 of them has laser chordectomy and 2 fronto-lateral laryngectomy). The time between laryngectomy and radiotehrapy was 4-15 weeks (mean 7 weeks). 22 patients (59%) were classified (due Sisson at al) as type I, 12 (32%) type II, 2 (6%) type III and 1 (3%) type IV. The treatment of stomal recurrences consisted of surgical resection of tumor, chemiotherapy, radiotherapy, brachytherapy or palliative treatment. 34 patients died, 2 are presently treated and 1 is near 5 years free of disease after surgical treatment. CONCLUSIONS: Patients with stomal recurrences begun primary treatment in locally and regionally advanced disease. In more that 60% of patients subglottic extension was observed. Emergency tracheotomy may predispose to stomal recurrence. Limited possibilities of treatment of stomal recurrences are the reason of very poor prognosis in this group of patients. During total laryngectomy paratracheal lymphatic nodes should be looked for and dissect.

[Rare case of the Recklinghausen disease in the head and neck region].

INTRODUCTION: Neurofibromatosis type I (Recklinghausen disease) is one of the most common genetic disorders. Symptoms in head and neck region are present in nearly 30% of cases, but the most frequent are skin café-au-lait lesions or lesions localized in craniofacial region. Neurinomas of the last four cranial nerves are also described. MATERIAL AND METHODS: We discuss a case of a 50-year woman admitted to our department because of chronic pain symptoms localized in the head and neck region. A rare case of neurinoma of the X and XII nerves in the neck region was stated. This patient was successfully treated surgically with removing tumors, which involved vagal and hypoglossal nerve on the right side. CONCLUSIONS: The causal treatment is until now unknown and patients are carefully observed and scan with MRI. The possible treatment for patients are surgery when the lesion become painful or for cosmetic reasons. Also surgery with radiotherapy is require for tumors with malignant transformation which is possible in 5% of cases. The genetic guidance should be proposed to NF1 patients.

[Functional endoscopic sinus surgery assisted by navigation system--own experience].

Functional endoscopic sinus surgery is nowadays a gold standard in case of chronic sinusitis. Microscopes and endoscopes are routinely used and the plan of the operation is based on physical examination and high resolution computed tomography of paranasal sinuses done in the bone frame. In the last few years trials were done with intraoperative navigation systems. This kind of system was tested in the ENT department of Karol Marcinkowski University in Poznań. Surgery was performed using electromagnetic and optical one. Thirteen patients with chronic sinusitis underwent surgery. A high resolution computed tomography was done in three planes. Then the data were transferred to the computer system. Those data were used to plan the surgery (determination of the "safe corridor") and in the intraoperative monitoring of the position of surgical instruments. We can state an improvement of the comfort for the surgeon and safety for the patient. We did not state disturbances in system work due to patient displacement during surgery. Accuracy and rapidity of the computer system allowed to perform safe surgery. Authors accentuate the usability of this system in case of reoperation, extensive pathological changes and in congenital malformations.

[A case of laryngeal papilloma with sudden dyspnea].

Laryngeal papilloma is one of the most common non-malignant tumors of the larynx. In adult they are included to pre-cancerous diseases. In morphological examination, it is a solid tumor. Often it is possible to cure them during one surgical procedure. The disease is mostly localized on the anterior commissurae region, vocal fold, ventricules, and on the laryngeal surface of the epiglottis. If the malignant transformation is suspected, a large excision with margin has to be performed, completed by a histological evaluation. A case of a huge laryngeal papilloma with dyspnea is presented.

[Sphenoid sinus surgery].

Sphenoid sinus surgery due to specific localization is placed in otolaryngologists and neurosurgeons field of interest. Surgery of this area, from one side, causes number of problems, which usually arise due to close neighbourhood of important structures, but on the other, serves as alternative approach, eliminating necessity of extended operations with craniotomies. The article summarizes results of sphenoid sinus surgery at ENT Department, University of Medical Sciences in Poznan between 1990 and 2003, as well as points out characteristic features of the surgery in this specific localization.

[Microscopy and endoscopy of the cerebellopontine angle in the retrosigmoid approach].

The retrosigmoid approach is one of the ways to the cerebellopontine angle. It's simple to perform and offers a good view in this difficult to reach area. It's a way to surgical cure of vertigo, microvascular compression syndromes and some kinds of acoustic neuromas. The operating microscopes is a basic tool of the surgeon in otoneurosurgery. For last few years straight rigid microscopes were introduced to have a better visualization without cerebellar mechanical retraction. They are useful complementary tools to existing methods. The authors present their experience on cadaver studies.
