Objective: To analyze potential etiology and outcomes of delayed facial palsy (DFP) after tympanomastoid surgery.
Methods: Fifteen cases of DFP out of 1582 cases after tympanomastoid surgery were reviewed, and the potential causes and outcomes were analyzed.
Results: 9 out of 15 patients (60%) had fallopian canal dehiscence and facial nerve exposure in contrast to 323 of 1567 patients (20.6%) without DFP, with significant difference (P < 0.01). Chorda tympani was cut or overstretched in 4 cases. There were two cases with herpes labialis and IgM antibody against varicella-zoster virus. All patients fully recovered within two months.
Conclusion: Fallopian canal dehiscence and facial nerve exposure was a risk factor of DFP after tympanomastoid surgery, and chorda tympani injury and viral reactivation may be triggering factors of DFP. The outcomes DFP after tympanomastoid surgery were excellent.
