Recurrent facial palsy: Characteristics of ipsilateral and alternative palsies of 104 cases.

Objective: Recurrent facial palsy is relatively rare and its clinical details of recurrent facial palsy are not well known. We analyzed recurrent facial palsy cases and clarified its characteristics, especially the difference between ipsilateral and alternative palsies. The analysis aimed to obtain information about recurrent facial palsy that would be useful for delivering explanations to patients and help improve recurrent facial palsy treatments based on the etiology.

Facial nerve course in the temporal bone: Anatomical relationship between the tympanic and mastoid portions for safe ear surgery.

Objective: Avoidance of iatrogenic injury to the facial nerve is crucial during ear surgery. The anatomical relationship between the tympanic portion of the facial canal (FC) and the mastoid portion of the facial nerve was analyzed using multi-slice computed tomography (CT) scans to avoid iatrogenic facial nerve injury.

Methods: In total, 364 ears of 351 patients who underwent CT scans were enrolled.
