Introduction The nerve-to-masseter is one of the most frequently used neural sources in smile reanimation surgery. Very little information has been reported on patient experience with regard to reanimated smile usage and sequelae following transfer. The aim of this study was to quantify patient perception of nerve-to-masseter use in smile reanimation surgery. Methods An online questionnaire was developed based on the clinical expertise of our team, patient interviews, and existing questionnaires of facial palsy-related quality of life and temporomandibular joint dysfunction. All patients treated with nerve-to-masseter-driven smile reanimation surgery, both nerve transfers and muscle transplantations, between 2007 and 2016 with a valid email address were invited to participate. Results Of 171 operated patients, 122 with a valid email address were invited to participate. Seventy-one patients responded (63.4% female, mean age 51.1 years) after a median follow-up of 3.8 years. A voluntary smile while biting down at least "most of the time" was reported by 83.1% of patients; 46.5% reported ability to smile on the affected side without bite. A "normal" or "almost normal" spontaneous smile was reported in 23.9% of patients. A total of 18.3% of patients self-reported masseter muscle atrophy, and 1.4–14.1% reported temporomandibular joint dysfunction. Forty-one patients (57.7%) reported prandial movement of the face at least "most of the time," with 9 patients (12.7%) considering this bothersome. Conclusion Patients report good voluntary smiling ability following nerve-to-masseter-driven smile reanimation surgery, with low rates of sequelae.
