What is the most appropriate surgical treatment for microstomia following avulsive tissue injury?

• A. Baloplasty
• B. Commisurotomy
• C. Osteotomy
• D. Genioplasty

Answer: (B)

The most appropriate surgical treatment for microstomia following avulsive tissue injury is commisurotomy. Microstomia, which refers to an abnormally small mouth opening, can result from significant trauma, including avulsion injuries to the oral tissues. Commisurotomy involves making an incision at the corners of the mouth, which can effectively increase the oral aperture by releasing any tight or contracted tissues. This procedure not only improves function by allowing for better access for eating and speaking but can also enhance aesthetics by allowing the mouth to open more normally. During commisurotomy, careful dissection and reapproximation of the tissue can minimize scarring and improve postoperative results. In contrast, baloplasty, osteotomy, and genioplasty are not typically indicated specifically for the condition of microstomia resultant from avulsive injuries. Baloplasty primarily addresses labial or oral deformities, osteotomy involves repositioning the jaw bones, and genioplasty focuses on the chin. These procedures do not directly address the functional and cosmetic concerns associated with microstomia following tissue avulsion.
