Factors Related to The Severity of Persistent Hypoesthesia after Bilateral Sagittal Split Ramus Osteotomy

Abstract
Bilateral Sagittal Split Ramus Osteotomy (BSSRO) is a widely used surgical procedure for correcting mandibular deformities, often resulting in a common post-operative complication: persistent hypoesthesia in the lower lip and chin. This study aimed to identify factors that related to the severity of this hypoesthesia post-BSSRO. We retrospectively analyzed treatment records of 33 patients who underwent BSSRO at an Oral and Maxillofacial Surgery clinic between October 2019 and October 2021. Neurosensory disturbance was assessed using a visual analog scale (VAS), and neurosensory function was objectively tested with 5-piece Semmes-Weinstein monofilaments on the lower lip and chin. Results indicated that the duration of post-operative follow-up was significantly associated with the severity of persistent hypoesthesia (P= 0.027). Moreover, intraoperative nerve encounter on the left side significantly related to the severity of symptoms, particularly in patients with normal to mild neurosensory disturbance (P = 0.014). The study concludes that extended post-operative follow-up, avoidance of intraoperative nerve exposure, and the expertise of the surgeon are key factors in reducing the severity of persistent hypoesthesia following BSSRO.
