This study presents a novel commissuroplasty technique using split dry lips to treat microstomia. The procedure successfully improved oral commissure deformities and mouth opening, enabling denture use.

Area of Science:

  • Plastic Surgery
  • Oral and Maxillofacial Surgery
  • Reconstructive Surgery

Background:

  • Microstomia, a condition characterized by reduced mouth opening, can result from various causes, including postoperative complications.
  • Corrective surgical interventions like commissuroplasty aim to restore oral function and aesthetics.
  • Traditional commissuroplasty techniques may have limitations in addressing severe deformities.

Observation:

  • A case of postoperative microstomia presented with significant oral commissure deformities.
  • The surgical approach involved a novel commissuroplasty technique utilizing split dry lip flaps.
  • The orbicularis oris muscle and cutaneous tissues were divided and repositioned into the cleft.

Findings:

  • The split dry lip commissuroplasty effectively corrected the deformities at the corners of the mouth.

  • Postoperative assessment revealed significant improvement in mouth opening.
  • The patient's improved oral aperture allowed for successful denture use.

    • Implications:

    • This innovative commissuroplasty technique offers a viable solution for managing microstomia.
    • The described method successfully combines functional restoration with aesthetic enhancement.
    • This approach may be beneficial for patients requiring correction of oral commissure deformities.
