[Detection of human papillomavirus type 16 and 18 in laryngeal cancer using PCR methods].

Human papillomavirus (HPV) is a small DNA virus. HPV is can be divided into two groups: mucosal and cutaneous. HPV have various oncogenic potential. The correlation between presence of high oncogenic type of HPV and carcinogenesis was confirmed in human anogenital tract and cervical carcinoma. The latest studies suggest HPV infection involvement in benign and malignant lesions of aerodigestive tract. The aim of our study was to determine the presence of the HPV genes E6/E7. The specimens were taken after total laryngectomy from 20 patients with squamous cell carcinoma. The fresh tissue specimens were frozen at -70 degrees C until DNA extraction and HPV detection. The presence of HPV DNA was assessed by polymerase chain reaction using specific primers for HPV 16 and 18 E6/E7. There were 7 (35%) HPV positive specimens in our group. 5 (25%) specimens were HPV 16 positive, 4 (20%) specimens were HPV-18 positive. In two cases HPV 16 and HPV 18 was present. The results suggest that high oncogenic types of HPV may play a role in pathogenesis of laryngeal carcinoma.

[Melanoma of nasal cavity and paranasal sinus mucosa].

In a group of 15 patients with malignant melanoma of the nasal cavity and paranasal sinuses the place of origin was nasal mucosa in 11 patients, the ethmoid cells in 2 cases and the maxillary sinus in 2 cases. Only 5 patients had tumour limited to infrastructure of the nasomaxillary complex, in 10 patients tumour occupied also suprastructure. Total maxillectomy was performed in 4 patients, partial maxillectomy in 8 patients with orbital exenteration in 3 patients. Of 12 patients operated on three patients died one year, two patients two years and one patient 6 years after surgery. One patient is alive 12 years, three patients are alive three years and one patient is alive one year after surgery.

[Free forearm skin flap with microvascular anastomosis for oral cavity reconstruction].

Free forearm skin-fascia flap was used in 8 patients for intraoral reconstruction. Tissue defect was located in anterior part of the oral cavity in three patients and in lateral part in 5 patients. In the first three patients microvascular anastomosis was performed first and the flap was sutured in the oral cavity later on. In one of these patients the whole flap and in two patients about half of the flap necrotised. In the next 5 patients oral defect was closed first and then microanastomosis was done with good result in all the patients. We advise the last type of reconstruction. Free forearm skin-fascia flap provides good anatomical and functional result of reconstruction in the oral cavity.

Short- and long-term results of stapedectomy in children.

Otosclerosis in children and teenagers is very uncommon. Typical otosclerosis presents as a slowly progressive conductive hearing loss and tinnitus in the third to fourth decade of life. Stapedectomy is a well-established procedure for correction of conductive hearing loss in adult patients with otosclerosis. The aim of this work is to assess short- (6 months) and long-term (7 years) results after stapedectomy performed in 10 patients under 20 years of age. In 1 patient cochlear otosclerosis was diagnosed and in 1 patient incus anomaly was found during the operation. Pure tone audiograms obtained 6 months after stapedectomy showed air-bone gap closure to 10 dB in 6 patients, to 15 dB in 8 patients and in all patients to 20 dB. Average air conduction threshold improved by 26.5 dB and average bone conduction threshold by 5.9 dB. 7 years after stapedectomy air-bone gap was similar to the one measured 6 months postoperatively. Stapedectomy in children provides good and stable hearing results.

[Free forearm skin flaps with microvascular anastomosis for pharyngeal reconstruction].

Free forearm skin flap with microvascular anastomosis was used for tissue defect reconstruction in 4 patients after resection of the oropharynx, base of the tongue and ramus of the mandible. The vascular pedicle of the flap contained the radial artery and the cephalic vein. For microvascular anastomosis the facial artery was used in all the patients, the facial vein in 2 patients, the internal jugular vein in one patient and the external jugular vein in the other one. Good healing of the graft was obtained in 3 patients. In one patient partial necrosis developed. No patient had fistula.

[Pharyngeal closure after pharyngolaryngectomy].

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.

[Face deformation and function defects after maxillectomy].

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.

[Platysma myocutaneous flap in intraoral reconstruction].

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.

Results of laryngeal cancer surgery in four ENT centers in poland.

The results of laryngeal cancer surgery were assessed in a group of 832 patients treated in four major ENT centers in Poland. Five-year survival rates were as follows: stage I, 86%; stage II, 71%; stage III, 54%; and stage IV, 42%. In experienced hands and for properly selected cases, cure rates after partial (conservation) laryngeal surgery were similar to those after total laryngectomy. For early stages (I and II), the survival after partial surgery was better than that found after radiotherapy.

Serum iron and total iron binding capacity in larynx cancer patients treated with surgery.

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.

[Comparison of auditory threshold and loudness in the Bing test].

The threshold and loudness comparison techniques of the Bing test were performed in a quantitative manner in both ears of 14 subjects. The results were related to their air-bone gap at 500 Hz. The study showed that the air-bone gap influenced a positive occlusion effect, but did not influence its subsequent magnitude. The magnitudes of the results of the occlusion test performed in these two ways were significantly related to each other.
