Abstract | OBJECTIVE: STUDY DESIGN: The study was a descriptive study-case report. SETTING: The study was conducted at a university-based otologic practice. PATIENTS: INTERVENTION: MAIN OUTCOME MEASURE: House-Brackmann facial nerve grade scores were used. RESULTS: Improvement of House-Brackmann facial nerve scores from Grade VI to Grade I-II in one patient, and improvement from Grade IV to Grade I-II in the other was seen. CONCLUSION: The probable etiology of delayed facial palsy is viral neuritis from reactivation of dormant virus within the facial nerve, initiated by thermal stress of the KTP laser. Presentation and resolution of the facial palsy is similar to other types of delayed facial palsy resulting from nonlaser techniques of stapes surgery and other types of middle ear and neurotologic surgeries previously reported.
