Temporal contour deformity, a depression in the temple area, can occur after craniofacial surgery. This study found fat pad volume reduction or displacement, not muscle issues, caused this common surgical complication.

Area of Science:

  • Plastic Surgery
  • Craniofacial Surgery
  • Anatomy

Background:

  • Temporal contour deformity is a concavity in the temporal region.
  • It can result from coronal flap elevation during craniofacial surgery.
  • Understanding its causes is crucial for surgical outcomes.

Purpose of the Study:

  • To describe anatomical and pathological features of temporal contour deformity.
  • To identify causative factors of this deformity after coronal flap elevation.
  • To analyze soft tissue changes contributing to temporal hollowing.

Main Methods:

  • Retrospective case series of 6 patients with unilateral temporal contour deformities.
  • Standardized data collection including dissection, clinical, and radiological findings.

  • Qualitative analysis of coronal magnetic resonance imaging (MRI) scans comparing affected and unaffected temporal regions.

    • Main Results:

    • No temporalis muscle atrophy or disinsertion was observed in any patient.
    • Diminution in superficial temporal fat pad volume was noted in 4 patients.
    • Inferior displacement or prolapse of the superficial temporal fat pad occurred in 2 patients.

    Conclusions:

    • Temporal contour deformity after coronal flap elevation is primarily due to superficial temporal fat pad changes.
    • Temporalis muscle integrity is maintained, indicating fat pad volume and position are key factors.
    • These findings aid in understanding and potentially preventing post-surgical temporal hollowing.
