 Facial nerve decompression is considered for severe peripheral facial nerve paralysis, and transmastoid approach is common in Japan. One of the important problems of this surgery is postoperative hearing loss. We measured pre- and postoperative hearing levels of the patients who underwent decompression surgery with temporary removal of incus in our hospital. The average of mean postoperative hearing loss at 500, 1000, 2000 Hz was 2.5 dB. Hearing loss at 125, 250, 4000, 8000 Hz were statistically significant. Sensorineural hearing loss in high tones and conductive hearing loss in low tones were the main causes of hearing loss.
