[The CO2 broncholaser in the treatment of subglottic and tracheal stenosis. Apropos of 14 cases]. / Le broncholaser CO2 dans le traitement des sténoses sous-glottiques et trachéales. A propos de 14 cas.

The authors report the results of CO2 broncholaser treatment in 14 cases of iatrogenic cricotracheal stenosis. A stable patency of the laryngotracheal airway was successfully obtained in 43% of stenoses treated with the broncholaser alone. In another 43% of patients improvement was obtained. Failure occurred in 14% of cases. Heat disruption of the cartilagenous support was the most frequent cause of failure and recurrence. The development of rigid bronchoscopes which can be coupled to CO2 laser would appear to us to be a real technical advance. The apparatus is easy to handle and is increasingly being used as first intention. It has several advantages compared to endoscopic materials used with the YAG laser. The effect of CO2 on the tissues would seem to be better adapted than the YAG for iatrogenic stenoses.

[Failure and complications of esthetic rhinoplasty. Apropos of 30 reoperations]. / Echecs et complications des rhinoplasties esthétiques. A propos de 30 rhinoplasties secondaires.

Out of 150 rhinoplasties carried out over 3 years in a Surgical Department. 20% of cases had previously undergone one or several surgical procedures. Based on these cases, the authors analysed the principal factors producing failure in cosmetic rhinoplasties and proposed a preventive strategy. The osteocartilaginous dorsum and point of the nose are considered separately in this paper.

[Neoplastic development of laryngeal amyloidosis. Apropos of a case]. / Evolution néoplasique d'une amylose laryngée. A propos d'un cas.

The authors report the case of a 62 years old patient who presented a squamous laryngeal carcinoma 8 years after the discovery of amyloidosis localized to one vocal cord. In this patient, a relationship would seem to exist between the two pathologies, with degeneration of amyloidosis being responsible, though a random coexistence cannot, of course, be completely excluded. After a review of laryngeal amyloidosis and its management, this particular case is discussed in relation to other cases described in the literature.

[Endoscopic surgery of the turbinates. Preliminary results]. / La chirurgie endoscopique des cornets. Etude préliminaire.

Turbinate surgery has become more precise thanks to miniaturisation and improvements in optical systems, therby allowing endoscopic surgery throughout the procedure including its posterior portion. Endoscopic turbinate surgery includes surgery of the hypertrophied middle turbinate "concha bullosa" which requires diagnosis for successful treatment (septoplasty, endonasal ethmoid surgery). Endoscopy has improved inferior turbinate cauterisation which has become more complete and precise especially for the posterior portion of the turbinate. It allows the use of new techniques: the YAG laser and the CO2 laser. Endoscopy allows good control during resection of the tail of the inferior turbinate and ensures hemostasis in the event of hemorrhage occurring during this procedure.
