Decompression of the facial nerve in Bell's palsy: a historical review.

This year, 1981, is the 50th anniversary of facial nerve decompression for Bell's palsy. The procedure was first suggested in 1923 but not performed until 1931. From the start, facial nerve decompression has generated disagreement regarding the indication and timing for surgical treatment and the anatomic extent of decompression. In each decade as the postonset time within which to perform surgical intervention has decreased, the anatomic extent of decompression has increased. Otologists continue to disagree, and we need to reevaluate our past and analyze how the difference may be resolved in the future. This critical review, in chronologic order, of the history and present status of facial nerve decompression is the necessary first step in resolving some of the persistent problems in surgical management of patients with Bell's palsy.
