[Repermeabilization of the laryngeal pathway using the laser].

Based on results in 48 cases, the principal indications and the place of laser in the repermeabilization of the glottic tract are discussed. Results on the cord adhesions were fair, whereas they were more constant with respect to regain of function in stenosis, paralysis and laryngeal edema. Laser can be used as single therapy by the endoscopic route for ankylosis or diplegia of the larynx, but should also act as a complement to a surgical or radiotherapeutic action.

[Comparison of results obtained by laser and conventional instrumentation in vocal surgery. Pseudomyxoma and nodules].

Surgery for pseudomyxoma or laryngeal nodules should always be as conservative as possible. This is obtained both by the use of the laser and conventional surgical techniques, results being analogous from the phoniatric point of view. From the technical aspect, however, the laser is a much simpler procedure.

[Evaluation of 6 years of CO2 laser microsurgery in laryngology].

Laryngeal microsurgery has been performed using a CO2 laser since 1978. It is essential to conduct a strict phoniatric pre-operative examination and to ensure correct anesthesia. Results after 735 operations underline the advantages of this technique for the treatment of benign laryngeal lesions (diffuse papillomatosis, sessile polyps, granuloma), in phonosurgery (nodules, bundle edema, corditis) and in the repermeabilization of the laryngeal network (paralysis, stenosis, laryngeal edema).

[Laser and phonosurgery (author's transl)].

Six patients are presented as examples of investigation and treatment of dysphonic patients in the ENT Department of the Tenon hospital, Paris. Investigations include photography, recording and sometimes sonograms before and after treatment. The multiplication of similar records will eventually show whether laser surgery should be preferred to instrumental surgery.

[Deep papillomatosis of the adult and laser (author's transl)].

Adult papillomatosis may be similar to child's papillomatosis or have an exophytic presentation. We describe a third kind of papillomatosis where papillomas tend to grow deep inside the mucosa. Laser seems an effective treatment of this condition which used to lead to tracheostomy and even total laryngectomy.

[Midline congenital fistulas of the nose. Fourteen cases (author's transl)].

The authors report 14 cases of midline congenital fistulas of the nose. Early diagnosis of the abnormality and its deep prolongations are necessary in order to avoid delayed presentation by infectious complications, which may be grave. Anteroposterior tomograms, in Gosserez view, in general provide precise information concerning the extent.

[Petromastoid clearance using plastic surgery in the surveillance of large cavities. Re-suture of the ear canal (author's transl)].

The lesions met with in chronic otitis media and especially in cholesteatoma, can be extremely widespread and, after petromastoid clearance there is a large resulting cavity which is impossible to survey by the usual route of the ear canal. A plastic surgical technique on the ear canal, is described which allows an easy surveillance without esthetic damage. It consists of a resection of a part of the cartilage of the ear canal with conservation of the skin of the inner and outer ear canal.

[Surgery for laryngeal stenosis in infants in liable in case of failure to produce a worse condition resulting on a definitive disability (author's transl)].

The proper treatment for these stenosis is the "evolutive calibrage" which takes advantage of the normal growth of the larynx with no risk of aggravation.

[Apneic anesthesia in unventilated patients for various operations and explorations in laryngotracheal surgery].

A technique of anesthesia is considered for laryngoscopy in suspension, and certain acts of surgery of the vocal cords, e.g. myxoma, and of the trachea, e.

[Trials of controlled hypotension with sodium nitroprusside in ORL surgery. Resistance and tachyphylaxis].

Sodium nitropusside has been used to lower blood pressure during surgical operations on the ear, nose and throat when an operative field without bleeding was desired, e.g. surgery of the inner ear under microscope in particular.

[Facial paralysis in children].

Facial paralyses in children may be grouped under headings displaying a certain amount of individuality. Chronologically, first to be described are neonatal facial paralyses. These are common and are nearly always cured within a few days.
