[Extension to the infratemporal fossa of malignant tumors of the face].

The authors report about the experience of the N&T department of Laënnec Hospital with tumors of the upper facial structures invading the infratemporal fossa. This invasion is currently diagnosed preoperatively owing to the progress made in imaging. The involvement of the posterior wall of the sinus is the first CT sign.

[Cancer arising in a cyst of the thyroglossal tract].

Two new cases of thyroglossal cyst carcinoma are reported. Such cancers concern rather young women. The diagnosis must be suspected whenever a thyroglossal cyst is associated with cervical adenopathies.

Vertical partial laryngectomy: a critical analysis of local recurrence.

The purpose of this study was to evaluate local recurrence following vertical partial laryngectomies in 416 patients with either T1N0M0 or T2N0M0 glottic carcinoma. Local failure was reported according to the T stage, the precise tumor location within each stage, the true vocal cord mobility, and the surgical procedure performed. No local recurrences were observed among 42 patients who underwent thyrotomy and cordectomy when the tumor was confined to the middle third of the mobile true vocal cord.

The authors report 7 cases of adenoid cystic carcinoma arising in the parotid gland between 1969 and 1990. All patients underwent surgery. Radiotherapy was performed twice following surgery.

[Combined approach to malignant tumors of the ethmoid and other paranasal sinuses. Principles and results].

The authors present their experience concerning combined transfacial and neurosurgical procedures in the treatment of carcinomas of the ethmoid sinuses. 109 ethmoid-spheno-orbital tumors were treated at our department from 1982 to 1990: 85 were located into the ethmoidal and/or sphenoidal sinuses; 78 of these were malignant. Among the 65 ethmoidal carcinomas which were operated through a combined route, 48 underwent an induction chemotherapy and 19 a post-operative radiotherapy.

[Olfactory mucosa and Alzheimer's disease. Technique for biopsy and ultrastructural study].

The discovery of a reliable peripheral marker would be of a great interest for the early diagnosis of the Alzheimer's Disease. The olfactory deficit and the major histologic changes of the olfactory-related areas of the brain occurring during this disease raised the possibility that the olfactory epithelia could be one of the way of entry of a possible process that still has to be identified. We have developed an instrument and a technique of biopsy of the human olfactory mucosa to search for the presence of characteristics lesions on patients suffering of an Alzheimer's Disease.

[Comparative study of temporal parameters of alaryngeal voices. Esophageal and tracheo-esophageal voices].

Recent studies have established significant acoustic and phonetic differences between tracheo-oesophageal (TE) and conventional esophageal voices (EV). 12 alaryngeal voices (2 esophageal, 6 myomucosal shunts, 4 tracheoesophageal phonatory protheses), and 7 normal laryngeal voices were recorded and analyzed. Speech timing including voicing and pauses distribution was evaluated and compared to laryngeal voices.

[Histiocytoma of the infratemporal fossa. Apropos of a case].

The authors present one case of histiofibroma of the infratemporal fossa. The difficulties in both diagnosis, treatment and histological prognosis of this tumors are discussed. The resection was realized through a cervicotransoral approach.

Supracricoid laryngectomy with cricohyoidopexy: a partial laryngeal procedure for selected supraglottic and transglottic carcinomas.

The partial horizontal supracricoid laryngectomy with cricohyoidopexy consists of resection of the whole thyroid cartilage and paraglottic space, as well as the epiglottis and the whole pre-epiglottic space. The cricoid cartilage, the hyoid bone, and at least one arytenoid cartilage are spared. Sixty-eight patients with squamous cell carcinoma of the supraglottis who underwent this procedure during the period from 1974 through 1986 are presented.

Supracricoid laryngectomy with cricohyoidoepiglottopexy: a partial laryngeal procedure for glottic carcinoma.

The partial horizontal supracricoid laryngectomy with cricohyoidoepiglottopexy consists of resection of the whole thyroid cartilage and paraglottic space. The cricoid cartilage, the hyoid bone, most of the epiglottis, and at least one arytenoid cartilage are conserved. Thirty-six patients with squamous cell carcinoma of the glottis who underwent this procedure from 1974 through 1986 are presented.

Treatment of Frey's syndrome with topical 2% diphemanil methylsulfate (Prantal): a double-blind evaluation of 15 patients.

Fifteen patients with severe gustatory sweating after total parotidectomy and facial nerve preservation were asked to take part in a double-blind study. All patients were alternatively treated with topically applied placebo and topically applied 2% diphemanil methylsulfate (an anticholinergic agent). A 10-day period was allowed between applications for return of symptoms.

[Oncologic protocol for solid tumors of the upper aerodigestive tracts. Protocol for collection of computerized data].

We present our method for treatment and follow up in patients with head and neck cancer. We have modified Laennec's Hospital Protocole (Paris), and afterwards we have developed a new computerized database system.

[Local and lymph node recurrence of epitheliomas starting in the glottis, treated by partial laryngeal surgery: apropos of 432 patients].

Four hundred and thirty-two patients with a carcinoma of the true vocal cord, treated with a partial laryngectomy from 1972 through 1984, were retrospectively analyzed. All patients were staged as NO, MO. Survival and death rates were not presented.

[Amalgamated and reinforced bone powder graft in the correction of the nasal ridge].

A number of surgical procedures have been described to correct irregularities of the consequences of excessive resection of the nasal ridge. Among these procedures the authors propose a bone powder graft mixed with tissue glue and reinforced with surgicel. The graft is in the form of a sheet of variable thickness which is malleable and can be perfectly shaped to fit the nasal ridge.

[Castleman's disease. Report of 2 cases with otorhinolaryngologic involvement].

Two cases of head and neck Castleman disease are reported. Diagnosis is always confirmed by histopathologic examination of the specimen. Head and neck and general localisations are described and discussed.

[Surgical treatment of associated bronchial, upper respiratory and digestive tract cancers].

Between 1980 and 1987, 63 lung cancers associated with upper aero-digestive tract carcinomas were operated on 50% of the primary malignancies of the upper aero-digestive system were laryngeal. These tumors developed synchronously in 13% and metachronously in 87%. The operative mortality rate was 3%.

Voice evaluation of myomucosal shunt after total laryngectomy: comparison with esophageal speech.

The vocal quality attained with a tracheoesophageal myomucosal shunt (MMS) as described by Strome was evaluated in four patients and compared with three esophageal speakers and two normal subjects. The patients with MMSs acquired speech sooner. Fundamental frequency, pitch, timbre, and melody were analyzed with computerized electroglottography and sonography.

[The Chinese flap in reconstructing the posterior pharyngolaryngeal wall, mouth cavity and in reoperation after failure of pedicled digestive transfer].

The Chinese flap has already been recommended in the context of circular pharyngolaryngectomy. The authors studied its vascularization from an anatomy-focusing project carried out on 40 dissection cases. They broaden the applications of this material to posterior reconstructive pharyngectomy, for which they specify the methods and routes of access.

[Lymph node failure in epithelioma of the glottic floor treated by partial laryngeal surgery. Apropos of 432 patients].

The authors assessed ganglionic failure in a series of 432 cases of N0 M0 epidermoid carcinomas of the glottic floor following partial laryngeal surgery. The overall of ganglionic failure was 7.8%.

[Tumors of the nasal fossa. Retrospective study of a series of 67 cases].

This retrospective study reviews 67 tumors of the nasal fossa treated at hospital Laënnec (Paris). The clinical significance of histology and the therapeutic results for each pathological tumor (mainly, carcinoma, melanoma, lymphosarcoma, neuroma, malignant plasmocytoma, inverted papilloma, vascular tumors) are described. Treatment and surgical procedure will be analyzed.

[Bronchial cancer associated with upper respiratory and digestive tract cancers].

The authors report a series of 63 cases, all operated, of bronchial cancer associated with upper airway cancer. The laryngeal portion of the upper airways was the site of cancer in 50% of cases. The two cancers occurred synchronously in 13% and at different times in 87% of cases.

Adenocarcinoma of the ethmoid sinuses. Results of a new protocol based on inductive chemotherapy combined with surgery. Four years experience.

New therapeutic modalities for Ethmoidal Adenocarcinomas are presented. Thirty three patients harbouring such a tumour have been treated during the last four years. Twenty three were included in the following protocol:--the first step consisted in inductive chemotherapy based on a four-day course of continuous cisplatine (CDDP) and 5-fluoro-uracyl (5-FU infusion)--the second step was the tumour removal, which was performed through a combined transfacial and subfrontal approach.

[Percutaneous endoscopic gastrostomy. Indications and results in 31 patients].

Nutritional assistance was indicated in 31 patients with an ENT tumour at different stages of treatment and different stages of the disease. These patients presented with disorders of deglutition with false passages (68%), aspiration pneumonia (10%), dysphagia (35%) or denutrition (17%). We used an endoscopic percutaneous gastrotomy kit produced by the Bioser company (pull technique).

Myomucosal shunt following total laryngectomy: a report of 31 cases.

An original technique of voice rehabilitation following total laryngectomy based on the concept of a myomuscosal unit was originally described by Strome. Thirty-one cases of myomucosal shunts (MMS) are analyzed in the present report. The 14 initial cases failed because of a lack clinical and surgical experience and insufficient selection of the patients.
