[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).

[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.

[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.

[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.

[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. This skin is used to re-suture the piece of cartilage which has been sectioned.

[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. In our experience, with the preparation used, sodium nitropusside proved to be a powerful hypotensive agent, the effect of which comes on early but it is difficult to use owing to frequent tachyphylaxis, the possible causes of which are considered. No undesirable side-effects were noted on the main functions. From this limited personal experience, the efficacy of this technique of per-operative hypotension did not appear greater in the surgical field under consideration to those of the anaesthetic techniques used commonly, e.g. neuroleptanalgesia under artificial ventilation, which proved sufficient for reduction in operative bleeding and which had already caused the authors to abandon, some time ago, the use of hypotensive ganglioplegic drugs.

[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.g. destruction of papillomatosis. The patient is in apnea, unventilated, a catheter brings down to the level of the carena a current of oxygen of 15 liters per minute, the gaseous acidosis is buffered by injections of a solution of molar sodium bicarbonate. After briefly recalling the notions which justify this technique, its repercussion on homeostasis is studied by arterial gasometry. General anaesthesia with apneic oxygenation may offer the ENT surgeon increased possibilities of exploration and operation at the level of the larynx and trachea, but owing to its biological consequences, it should be used only with circumspection and its indications should be totally justified, for acts of limited duration. The technique seems, at present, difficult to adapt to surgery with laser.
