Abstract：Objective To assess the value of transmastoid facial nerve decompression for patients with Bell’s palsy. Methods Thirty three patients who displayed more than 90%degeneration on ENoG were offered transmastoid facial nerve decompression. The timing, site and outcomes of the surgery were discussed. Results Transmastoid facial nerve decompres-sion involving the geniculate ganglion and distal portion of the labyrinthine segment was effective in 77.3%of the cases, of which 54.5%recovered to H-B level I or II. In patients who received decompressive surgery within 3 months after the onset of facial palsy, 62.5%recovered to H-B level I or II, although this ratio was 70%when decompression took place within 2 months after symptom onset, with no grade IV or worse outcomes. Conclusions Within 3 months after facial palsy onset, surgi-cal decompression medial to the geniculate ganglion significantly lowered the chance of developing poor facial function re-sults in patients with Bell’s palsy.
