Rehabilitation of the olfactory sense after laryngectomy: long-term use of the larynx bypass.

Patients who undergo laryngectomy typically lose their sense of smell. One device that has been used to rehabilitate olfactory function in these patients is the larynx bypass. We conducted a long-term study of the larynx bypass in 16 laryngectomized patients.

[Is orbital exenteration indicated for extensive primary mucosal melanomas of the sinunasal system?].

Primary mucosal melanomas are most frequently localized in the sinunasal system. Orbital involvement must be excluded in the mostly advanced tumor stage. The aim of our study was to find possible indications for orbital exenteration in the T3-4 sinunasal tumor stage.

[Neurilemmoma of the head and neck--report of 3 cases].

Background: Neurilemmoma are benign tumors of the nerve-sheath, also known as schwannoma. Beside intracranial manifestation, neurilemmoma are found at other peripheral nerves of the head and neck.

Case Report: We present three cases of patients with seldom manifestation of neurilemmoma of the supraglottis, the retropharyngeal space and a neurilemmoma of the hypoglossal nerve.

[Rehabilitation of the olfactory sense after laryngectomy -- the larynx bypass].

Background: Patients after laryngectomy lose their previous sense of smell, since air normally circulates via the tracheostoma and active air intake through the nose is no longer possible. The larynx bypass with a throat mask is an aid here. Nasal air circulation is made possible by this connecting piece between the mouth and tracheostoma.

Hyperfractionated accelerated chemoradiation with concurrent fluorouracil-mitomycin is more effective than dose-escalated hyperfractionated accelerated radiation therapy alone in locally advanced head and neck cancer: final results of the radiotherapy cooperative clinical trials group of the German Cancer Society 95-06 Prospective Randomized Trial.

Purpose: To report the results and corresponding acute and late reactions of a prospective, randomized, clinical study in locally advanced head and neck cancer comparing concurrent fluorouracil (FU) and mitomycin (MMC) chemotherapy and hyperfractionated accelerated radiation therapy (C-HART; 70.6 Gy) to hyperfractionated accelerated radiation therapy alone (HART; 77.6 Gy).
