Abstract

Aim: To demonstrate the first report on Masseteric–facial nerve reanimation in Thailand. Background: Facial nerve paralysis is devastating for patients. Most of the patients suffer from stigma and social phobia. There are many options for treating the facial nerve paralysis including dynamic and static procedures dependent on the patient situation. Masseteric–facial nerve reanimation is a dynamic procedure suitable for the patient in the absence of a proximal facial nerve stump, with low donor site deformity and being easy to train in the postreanimation phase. We applied the first facial reanimation by masseteric–facial nerve anastomosis to a Thai patient. Review result: The patient had right facial nerve paralysis from the right temporal bone fracture in a motorcycle accident. The patient developed delayed onset of complete paralysis. After exploration, operative findings showed a torn right facial nerve at the tympanic segment of the geniculate ganglion and second genu. Masseteric–facial nerve anastomosis was applied for this patient. The right greater auricular nerve was used for the nerve graft to connect between the proximal stump of the masseteric nerve and the distal stump of the main trunk facial nerve. There were no postoperative complications. After 3 months, the postoperative facial muscle tone returned and after 4 months, when the patient tried chewing using the masseter muscle, some movement of the facial muscle was detected. Conclusion: Masseteric–facial nerve reanimation is the treatment of choice for dynamic facial nerve reanimation in facial nerve paralysis patients where the proximal nerve stump is absent or in the cases of intratemporal injury to the facial nerves.
