[Role of tubal insufflation in the postoperative follow-up of évidement cavities].

The authors report their experience of tubal insufflation in the post-operative care of cavity évidement. Their indications consist of évidement cavities with persistent residual muco-purulent otorrhoea or "glue ear" from the atrial area which remains thickened, while the rest of the cavity is healed (about 15% in their statistics). The technique is simple, consisting essentially of insufflations of air by means of an Itard catheter, which are repeated at regular intervals for a variable period of time. In some cases, drugs, in particular corticosteroids, are injected into the cavity via the catheter. In a series of 17 operated patients, the authors report: 9 excellent results in which drying of the cavity was obtained in record time; 4 good results in which drying of the cavity required numerous insufflations associated with systemic treatment (vaccine therapy, crenotherapy); 1 moderate result with transient persistent otorrhoea; 3 failures.
