[Failures after tympanoplasty].

Failures and pitfalls in chronic ear surgery have been studied. The material consists of a retrospective study of 616 cases of tympanoplasty. The results were mainly analysed into cases of iatrogenic cholesteatoma (23), labyrinthine fistulae (25) and disruption of ossicular chain (46). The incidence of fistula into the semi-circular canal is high with cholesteatoma, and careful removal of the matrix is recommended to prevent sensorineural hearing loss. Disarticulation of the incudo-stapedial joint is performed to eradicate attic cholesteatoma and protect the cochlea. However, this procedure gives a risk of damage to the inner ear. The frequency and nature of sensorineural losses following chronic ear surgery have been discussed. Surgical precautions are advocated to prevent inner ear damage or other iatrogenic complications.

[Section of the facial nerve. Apropos of 40 cases].

From January, 1985 through December, 1992, 40 patients were referred to the Department of Otoneurology of the Lille University Hospital for traumatic facial nerve injury. The injury was located in the intracranial, intratemporal, or extracranial segments of the nerve in 19, 15 and 6 patients, respectively. The trauma was iatrogenic in 30 patients. It was the result of surgery for a tumor of the posterior fossa, of the temporal bone or of the parotid in 19, 2 and 3 patients, respectively. Nerve injury had occurred during surgery for chronic otitis or a parotid fistula in 5 and 1 patients, respectively. Finally, it was the result of temporal bone fracture in 7 patients. We used various techniques for repair of the nerve. Anastomosis, whether end to end or with an interposition graph and with or without rerouting, was accomplished in 17 patients, as often as possible during the first month following injury (12/17 patients). Hypoglossofacial crossovers were used in 23 patients. Evaluation of the results may vary according to the choice and interpretation of an international facial nerve grading system. We define 4 categories of results: satisfactory, moderate poor and no improvement. The results of anastomosis were best when the repair with or without rerouting was undertaken as soon after injury as possible (7 satisfactory results for 16 patients evaluated). Hypoglossofacial anastomosis gave 5 satisfactory results for 17 patients evaluated. Following this operation a spastic tendency is frequent and seems more important in patients operated during the two months following nerve injury.(ABSTRACT TRUNCATED AT 250 WORDS)

[Retrocochlear deafness, acoustic neurinoma and early evoked auditory potentials--apropos of a series of 113 patients].

The results of brainstem evoked response audiometry (BERA) in a series of 113 patients with neurosensory hearing loss from both tumoral and non tumoral origin are reported. In 37 cases of non tumoral pathology, confirmed by CT-scan or NMR (14 cases) a retrocochlear type of evoked response was observed. The tumoral cases were mainly neurinomas (70 cases). There was a kophosis in 14 cases, typical retrocochlear responses in 52 cases, doubtful responses in 2 cases and in another 2 cases no electrophysiological disturbances could be observed. The systematic stimulation at 4 KHz seems to sensitize the BERA method. According to the authors it remains the first choice investigation technique of unilateral hearing loss. The results of this study are compared with those of the literature.
