    Abstract:
    INTRODUCTION: Neurological sequelae of infraorbital nerve (ION) lesion 6 months after orbital floor or zygomaticomaxillary complex (ZMC) fractures, associated with initial ION injury, were compared according to the treatment performed and the type of fracture. The topographic and symptomatic sequelae at 6 months were described. MATERIALS AND METHODS: Patients with orbital floor or ZMC fracture associated with initial ION injury, between November 2018 and April 2020 and clinically reassessed 6 months after trauma were included. Detailed neurological symptomatology was assessed by a questionnaire. RESULTS: A total of 81 patients were included. Forty-two patients (51.8%) showed persistent neurological signs, i.e., isolated hypoesthesia in 28 patients (66.7%), isolated pain in 10 patients (23.8%) and both in 5 patients (9.5%). The most affected area was the cheek (42.8%). Thirty-eight patients (46.9%) presented associated signs, which were intermittent in 78.9% of cases. A pronounced improvement happened for 65.1% of patients and 76.7% were not or only slightly hindered in their daily activities. There were significantly more neurologic symptoms at 6 months in the surgical group than in the observational group and more in the ZMC fracture group than in the orbital floor fracture group. DISCUSSION: Neurological symptomatology was more frequent in patients treated surgically. Our results suggest the interest of a surgical decompression when orbital or ZMC fracture is associated with nerve damage but more data are needed. Neurological injury requires a careful initial clinical evaluation and regular follow-up to help patients coping, painful symptoms may benefit from specialized care.
