What is a commonly noted complication following BSSO?

• A. Bone resorption
• B. Paresthesia
• C. Chin asymmetry
• D. Facial nerve damage

Answer: (B)

Paresthesia is a well-documented complication following Bilateral Sagittal Split Osteotomy (BSSO). This surgical procedure involves cutting the mandible to reposition it, usually to improve occlusion or aesthetic appearance. During the operation, the inferior alveolar nerve, responsible for sensation in the lower lip and chin area, can be traumatized or displaced. This nerve damage can lead to altered sensations, which may manifest as numbness, tingling, or a feeling of 'pins and needles' in the affected areas. These sensory changes can be temporary or, in some cases, may persist long after the surgery. While other complications such as bone resorption, chin asymmetry, and facial nerve damage can occur in the context of BSSO, they are not as commonly reported or directly associated with the surgical technique as paresthesia. Bone resorption is typically related to other factors, such as the quality of the bone and the healing process, while chin asymmetry may arise from surgeon technique or healing discrepancies but is less frequent with proper surgical planning and execution. Facial nerve damage, though a potential complication, is much rarer and is typically associated with procedures involving the maxilla or deeper structures, rather than the mandible alone. Thus,
