What percentage of patients experience objective neurosensory disturbance one year after a BSSO procedure?

• A. 0-2%
• B. 2-9%
• C. 10-15%
• D. 15-20%

Answer: (B)

Following a bilateral sagittal split osteotomy (BSSO), neurosensory disturbances are a recognized complication, with the incidence varying across studies. A one-year follow-up period post-surgery is critical for assessing the persistence of these disturbances.

Research indicates that approximately 2-9% of patients report experiencing objective neurosensory disturbances at the one-year mark. This percentage reflects the transient nature of many sensory changes following surgical intervention, where a significant proportion of patients gradually regain normal sensation over time. While most patients recover fully, some may experience lingering effects.

The given range of 2-9% for objective disturbances aligns with the expected outcomes noted in the literature, thus making it the most accurate choice in this context. Understanding this range is essential for managing patient expectations and educating them on potential postoperative outcomes.
