    Neurological damage after sagittal split osteotomy can cause sensory loss. While most patients feel normal, objective tests show significant sensory deficits in many cases.

    Area of Science:

    • Oral and Maxillofacial Surgery
    • Neurosurgery
    • Anesthesiology

    Background:

    • Sagittal split osteotomy is a common surgical procedure.
    • Neurological damage, specifically sensory loss, is a known complication.

    Purpose of the Study:

    • To evaluate the long-term sensory outcomes following sagittal split osteotomy.
    • To compare subjective patient reports with objective neurological assessments.

    Main Methods:

    • Retrospective analysis of 38 sagittal split osteotomies in 19 patients.
    • Minimum follow-up period of 2 years post-surgery.
    • Subjective sensory evaluation by patients.
    • Objective sensory testing by clinicians.

    Main Results:

    Related Experiment Videos

    • Subjective evaluation indicated normal sensation in 73.7% of operated sides.
    • Objective evaluation revealed normal sensation in only 34.2% of operated sides.
    • A significant portion of patients experienced variable degrees of sensory loss upon objective testing.

    Conclusions:

    • Subjective assessment may overestimate sensory recovery after sagittal split osteotomy.
    • Objective testing is crucial for accurately diagnosing neurological deficits.
    • Long-term sensory deficits are more prevalent than patient-reported outcomes suggest.
