Background. The aim of the present study is to find the site of traumatic facial nerve paralysis and to compare the results of preoperative tests with operative findings.
Methods. This is a prospective study on 38 cases of traumatic facial nerve paralysis, managed at the Post Graduate Institute of Medical Education and Research (PGIMER) Chandigarh, India. The results of radiology, audiology and topographic tests were compared with peroperative findings.
Results. We found the mastoid segment to be involved in 55.26% cases which is contradictory to those mentioned in the literature. This is probably due to a different mode of injury as most of the cases we encountered followed falls from two wheelers. 55.26% cases had impinging bony spicule onto the facial nerve and in another 28.95% cases only edema and granulations were present. 46.43% cases had excellent improvement within six months of facial nerve decompression.
Conclusions. Surgery should be done as soon as electrodiagnostic tests indicate severe injury and predict poor prognosis. An immediate facial paralysis following slow progressive degeneration is found to have good prognosis whereas delayed paralysis with rapid onset degeneration should also be treated surgically in order to ensure recovery.
