PURPOSE: The purpose of this study is to introduce the results of a new surgical technique in patients with complete facial nerve palsy using the dynamic muscle transfer of orbicularis oculi muscle (OOM) flap from the contralateral side. METHODS: This case series presents a new surgical technique in three patients with complete facial palsy and lagophthalmos who were unresponsive to other modalities. In this technique, a rectangular flap of OOM was dissected from the upper lid of fellow eye and transferred to the affected eye through a subcutaneous tunnel over the nasal bridge. The flap was divided into two halves for upper and lower lids. Each half was incised longitudinally to increase the length of the flap and cover the lateral part of the affected eyelids. RESULTS: Improvement in exposure keratitis, lagophthalmos, and other related symptoms was observed as soon as the 1st week after the surgery. Partial blinking recovered and the operation was uneventful. CONCLUSION: Muscle flap transfer technique using contralateral OOM for complete facial palsy can be considered as a helpful alternative in patients who are still symptomatic despite conventional treatment modalities.
