Summary
Surgical correction of microstomia (small mouth) improved mouth opening and appearance in five patients. Careful evaluation of causes and tailored surgical techniques are key for optimal functional and aesthetic outcomes.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
Background:
- Microstomia, characterized by a small mouth, causes functional impairments like difficulty eating and speaking, alongside cosmetic concerns.
- Existing treatment methods for microstomia lack universal applicability.
- This study critically reviews institutional cases and literature to analyze microstomia treatments.
Purpose of the Study:
- To analyze surgical treatments for microstomia at our institution.
- To critically review the literature on microstomia management.
- To evaluate functional and cosmetic outcomes of surgical interventions for microstomia.
Main Methods:
- Retrospective review of medical records for microstomia patients treated between November 2015 and April 2018.
- Analysis of etiology, chief complaint, surgical method, and outcomes in surgically treated patients.
- Evaluation of functional outcomes (mouth opening, intercommissure distance) and patient-reported cosmetic satisfaction.
Main Results:
- Five microstomia cases were surgically corrected, with etiologies including chemical burns, skin cancer excision, and Stevens-Johnson syndrome.
- Surgical methods included full-thickness skin grafts and various buccal mucosal flaps.
- Average improvements were 6.0 mm in mouth opening and 7.2 mm in intercommissure distance, with good to excellent patient satisfaction.
Conclusions:
- Microstomia arises from diverse causes.
- Precise evaluation of etiologic factors and impairment severity is crucial.
- Careful selection of appropriate surgical methods ensures optimal functional recovery and aesthetic improvement.
