[Laser surgery in the treatment of bilateral vocal cord paralysis].

The introduction of surgical lasers into microsurgery of the larynx has made the resection of the posterior vocal cord with or without the arytenoid cartilage possible. This method of surgical treatment allows one to carry out a fast, non-open larynx procedure and practically bloodless operation with minimal postoperative trauma and edema of the surrounding tissues. Since November 1990 at the Clinic of Otolaryngology of the University School of Medical Sciences 48 arytenoidectomies (40 on the right side, 8 on the left side), 19 partial chordectomies and 25 Kashima operations. All surgical treatment were performed by means of CO2 laser in patients with bilateral paralysis of the vocal cords. In all patients postoperative recovery was correct and breathing difficulties were not observed after extubation. Laryngoscopic control examinations were performed a day after operation and a wide lumen of air through the operative field was observed. At the control examination, narrowing of the lumen of the larynx was not observed, the healing process of the operation area was without granulation. Laser arytenoidectomy allows good results of the breathing and phonation function. No changes of granulation proliferation were observed at the side of the CO2 laser treatment. Lack of reaction to laser beam there was possibility to use endoscopic procedures in patients who did not undergo a tracheotomy.

[Multiple primary neoplasms on the face].

A case of 74-year old woman with six separate cancers is presented. Four of them were nonmelanoma skin cancers (2 basal-cell carcinomas and 2 squamous-cell carcinomas), the remaining two were noncutaneous malignancies (invasive lobular carcinoma of the breast and squamous cell carcinoma of the parotid gland). Three lesions were present simultaneously on the head and neck region; basal-cell carcinoma on the cheek, squamous-cell carcinomas on the forehead, and in the parotid gland. All neoplasms were surgically removed, the region of affected parotid gland was additionally radiated. Extreme rarity of the multifocal primary malignancies is emphasized and the non-completely clear etiology, biology and pathology of these tumors is discussed.

[Tinnitus in systemic diseases].

Permanent or temporary degenerative changes in the internal ear causing tinnitus may occur with particular intensity in patients suffering from systemic disease (diabetes, hypertension, rheumatic diseases, kidney and thyroid gland diseases). Pathomechanisms of hearing impairment and the risk of tinnitus and its character in particular cases are discussed in the paper. The research was carried out on 1200 patients treated in the Laryngological Rehabilitation Centre in Poznań between 1.1.1998 and 04.2001 due to tinnitus. The analysis included the diagnosis of general health condition, general laryngological examination as well as additional tests. In the examined group 34% suffered from systemic diseases. Among them the highest percentage (47%) suffered from hypertension, 41% from hypercholesterolaemia, 22% from rheumatic diseases and 16% from diabetes. 96% of the patients had a long family history of diseases. The additional factor causing damage of the internal ear may be ototoxic drug used in the treatment of many systemic diseases.

[Ultrasonography in diagnosis of neck tumors].

Tumours of the neck are very important problem of the contemporary otolaryngology. In the study the use of sonography in evaluation of expansions of the neck was studied in 200 patients with histologically proven diagnosis. To carry out a detailed evaluation of the individual character of particular types of tumours, all basic features were analysed using the following criteria: echogenicity, echostructure, separation and contour. In this group developed 159 (78.5%) benign tumours and 41 (21.5%) malignant tumours. Malignant tumours were mainly: cystic or solid-cystic, with irregular contour, thickened separation and high echogenicity. Benign tumours were regular, smooth, with low echogenicity and clear separation.

[Objective audiometry in diagnosis of tinnitus].

During last 3 years there have been 900 tinnitus patients treated at ENT Rehabilitation Center in Poznan. Everyone underwent a thorough laryngological and audiological examination. Diagnostic procedure comprised also neurological and endocrinological consultations with accessory blood tests. Wide group of audiological tests used for diagnosis was divided into objective (BERA, OAE, tympanometry, stapedius reflex) and subjective (pure tone audiometry, speech audiometry, suprathreshold audiometry) methods. Otological diagnostic in tinnitus patients is difficult due to its subjective character. That is why it is so important to have objective methods for its evaluation. In this paper authors present results of BERA tests and impedance conducted on group of 900 patients. Performed objective tests enabled to diagnose otosclerosis, chronic otitis media and pathology in cerebello-pontine angle in patients without any abnormalities on physical examination.

[Laryngocoele].

Three cases of laryngocoele operated in ENT Department University of Medical Sciences in Poznań by an external approach are presented. Role of larynx tomography in diagnosis procedure and surgical technique is emphasised. Origin, classification, diagnosis and treatment methods are discussed.
