Pharyngolaryngectomy was performed in 53 patients. In 36 patients pharynx defect was less than 50% of pharynx circumference and it was closed without reconstruction. Larger pharynx defects were closed using platysma myocutaneous flap (13 cases), pectoralis mayor flap (3 cases) and free forearm flap with microvascular anastomosis (1 case). Healing results are presented in each group of patients.
The results of immunohistochemical investigations of BCL-2 presence in 50 patients with laryngeal carcinoma were presented. In 14% of all investigated cases presence of BCL-2 protein was observed. In patients with advanced clinical stage of laryngeal carcinoma higher expression of BCL-2 protein comparing with patients with lower clinical stages was more frequently observed--but it wasn't significant. No significant difference in presence of BCL-2 protein among the patients with a different stage of histological differentiation of carcinoma and among the patients with present and absent metastatic changes in regional lymph nodes was observed.

On the basis of 7 cases of temporal bone paraganglioma diagnosis of this tumor is presented. Apart from aural symptoms cranial nerves palsy may appear. Computer tomography, magnetic resonance imaging and subtraction angiography are essential investigations.
In the group of 42 patients after maxillectomy face deformation and function defects were assessed. The best cosmetic and functional result was observed after maxillectomy without orbital exenteration, with preservation of lateral part of the zygomatic bone and at least a half of nasal skeleton. Severe face deformation developed after orbital exenteration, resection of the palpebrae, cheek and external nose.
Plastyma myocutaneous island flap was used in 13 patients to reconstruct tissue defect after oral cancer surgery. Necrosis of the skin island in the oral cavity occurred in 3 patients. A fistula developed in one patient with a large defect of the tongue, pharynx and mandible. In 12 patients wound healing on the neck was good. Plastyma myocutaneous flap is very useful to close defects of the floor of the mouth and up to the half of the tongue width.
The amount of use of hearing aids was assessed in 190 adults and 22.6% of them used the aid always, 23.7% most of the day, 22.6% every day a little, 20.0% sometimes and 11.1% never. The hearing aids were used more by patients with profound hearing loss than by patients with moderate loss and more by younger and working subjects than by elderly and non-working ones.
Auditory disability was studied in a group of 140 Polish hearing aid candidates using an oral presentation of the problem questionnaire of Barcham and Stephens (1980). The overall pattern of problems reported by Polish hearing-impaired patients was similar to that found among English respondents. Some difference in the prevalence of the problems emerged which may result from the different socio-economic situations in the two countries.
A decrease in serum iron and total iron binding capacity (TIBC) has been seen in patients with various malignancies. Similar iron level and TIBC alterations we have found in patients with larynx cancer. Estimation of TIBC reflects the quantity of transferrin which is the iron carrier in serum. The serum iron and transferrin changes cannot be used for diagnostic purposes because they are not specific to malignancies. Such alterations have been also seen in inflammatory and infectious diseases, heart infarct and anaemias. However, it is of interest whether elimination of neoplastic tissue from an organism brings back the decreased serum iron and TIBC to normal values.
Benefits of hearing aids were studied in a group of 169 patients using an open-ended self-report approach. The overall pattern of benefits was qualitatively similar to the pattern of complaints reported by candidates for hearing aids (Golabek et al., 1988). The response pattern was related to the age and work of the hearing aid users, to the level of the hearing loss in the better ear and to the amount of use of the hearing aid.

History and results of investigations in 34 patients with cerebello-pontine angle tumours are presented. Tumour was diagnosed in the first, audiological stage of the disease only in 4 patients. In 7 more patients additional symptoms of central nervous system focal disorders occurred. The remaining 23 patients were in the third stage of the disease with symptoms of increased intracranial pressure. The main reason for such a late diagnosis of the tumour was neglecting of the early audiological symptoms of the disease by patients and by general practitioners as well.
