[Combined middle and inner ear abnormality: report of a case].

Congenital anomalies of the middle ear associated to anomalies of the inner ear are rarely described. Our case displays a malformation due to an association of congenital absence of the round window and aplasia of the semi-circular canals, causing conductive hearing loss. First diagnosis was a congenital atresia isolated of the round window, related to a previous surgical exploration. We tried a novel technique designed to restore the function of the round window. Labyrinthine anomalies prevented a good outcome. This kind of malformative association could be due to the complexity of early genetic control of ear development. Attentive analysis of imaging should be performed before middle ear surgery to determine the presence of inner ear anomalies which are quite frequent and which would limit its usefulness.

[Functional endoscopic sinus surgery. Evaluation methods and results].

Functional Endoscopic Sinus Surgery (FESS) is now undoubtedly the choice procedure for the surgical treatment of chronic sinusitis and nasal polyposis after failure of medical treatment. Between January 1990 and December 1992, 51 patients with chronic sinusitis and 44 with nasal polyposis who underwent FESS were evaluated (170 ethmoidectomies). Preoperative evaluation is obtained through personal scaling combined with a CT of the sinuses, whereas postoperative assessment is based on the same scoring together with an endoscopic evaluation. Good functional results and no significant differences between the two types of pathology are obtained after a 1 year follow-up.

[Sleep apnea syndrome. Evaluation following uvulopalatopharyngoplasty].

20 cases of uvulopalatopharyngoplasty performed on patients suffering from sleep apnea syndrome have been studied with a pre- and post-operative polysomnographic recording. Eleven patients (55%) responded to this therapy and showed a significative decrease of their post-operative apnea-hypopnea index. An increase of the mean oxygen saturation was noticed during sleep. On the contrary, the sleep quality did not improve. Age, weight, apnea index are not predictive factors influencing the result of UPPP. Even if UPPP has a relatively poor success rate it still should be proposed to patients suffering from sleep apnea syndrome as it remains the simplest and best tolerated surgical treatment.

[Evoked auditory responses in subjects with normal hearing].

Evoked acoustic emissions is a new clinical method proposed for the exploration of the cochlea and also for infant screening. Eighty five normal hearing ears were screened by this technique. Clinical potential of this technique is discussed.

[Evoked otoacoustic emissions. Results in hypoacusis].

Otoacoustic emissions are present in the majority of normal hearing ears. Hearing loss of different types generally doesn't show evoked acoustic emissions. Sixty-seven impaired ears of different degrees and types where examined to precise the kind of hearing losses unable to elicit oto-acoustic emissions.
