Resections and end-to-end anastomosis have been effective in correcting localized tracheal strictures. Important clinical considerations are the precise preoperative assessment of the lesion, careful planning of anesthetic management and choice of the appropriate decision. Surgical procedures involving sharing of the air way between the anaesthetist and the surgeon impose special problems on the anaesthetist. On the one hand, the surgeon requires unrestricted access to the operating site and on the other, the anaesthetist must ensure adequate anaesthesia, oxygenation and carbon dioxide elimination, preferably without contamination of the lung fields. The more commonly employed technique is the use of a tracheal tube so that anaesthesia can be maintained using conventional IPPV. In our experience, the majority of strictures in adults can be managed as well, or better, by using a conventional endotracheal tube.
The authors describe two clear-cut cases of hypopharyngeal lateral diverticulum. They have found only 22 published cases. They discuss the nosological limits of the physiological pharyngeal expansions visible under high pressure pharyngography, those of kinetic pharyngoceles which are often forced hernias, finally, the very real but uncommon presence of true lateral diverticula. The passage of barium Therapeutic indications are discussed. The surgical technique is simple.

The authors describe the clinical picture of the aspirin idiosyncrasy and propose to call this peculiar entity: syndrom of Widal and Lermoyez. They compare 25 cases of aspirin nasal polyposis with 26 other cases of various etiologies. Other substances than aspirin seem to be charged. The complications are regular with severe asthma and infection. The pathogenesis is discussed, excluding an allergic mechanism; it remain not quite clear. Essentially prophylactic, the treatment is poor and difficult.
