Abstract

Microstomia can be occurred as a result of direct injury to tissues such as chemical, thermal and electrical burns, and animal bites. It also may be secondary to contracture of burned perioral skin, or may result from scarring after reconstructive lip surgery. Narrowing of the oral aperture is not only disfiguring, but also limiting the oral access needed for introduction of food, insertion of dentures, oral hygiene, and dental treatment. Limited mouth opening may also interfere with mastication and speech. Few reports exist regarding correction of microstomia and reconstruction of the corners of the mouth. A 16-year-old girl with a bilateral cleft lip and palate presented with the limited mouth opening (approximately 20 mm), the esthetic problem due to the small lip, and the cleft lip-nasal deformity. The microstomia was corrected by bilateral commissuroplasty using "over and out" buccal mucosa flaps proposed by Converse. The intercommissure distance was increased from the preoperative 40 mm to the postoperative 60 mm. The one-year postoperative intercommissure distance was 54 mm, because the 6 mm relapse was occurred. The bilateral commissuroplasty using "over and out" buccal mucosa flap could increase the width and general size of the oral aperture and improve the lip appearance.

양측성 구순구개열을 가진 16세 여자 환자가 소구증과 구순열비변형으로 인하여 개구 제한과 심미적 문제를 주소로 내원하였다. 병력에서 구순성형술, 구개성형술 그리고 이차구순비성형술을 받았으며, 임상 소견에서 상순과 하순이 매우 작고 입술의 폭은 40 mm 정도로 짧았으며 최대 개구량은 20 mm였다. Converse의 협점막 외전 피판을 이용한 양측성 구각성형술을 시행하였으며 수술 후 입술의 폭은 60 mm로 증가하였다. 수술 1년 경과 후 입술의 폭은 54mm로 약 6 mm 정도 회귀되었고, 그 외에 별다른 문제점 없이 심미적, 기능적으로 양호한 결과를 보였다. 협점막 외전 피판을 이용한 양측성 구각성형술은 입술의 폭과 크기를 증가시켜주고 입술의 외관을 개선하여 소구증의 외과적 교정에 적절한 술식임을 알 수 있었다.
