Abstract

Oral vestibule is important in oral health. Various vestibuloplasty techniques are used in cases involving vestibule loss. This case report describes the treatment outcomes from performing modified Kazanjian vestibuloplasty with artificial der-mis graft and connective tissue graft for severe trismus and mandibular denudation caused by shallow vestibule and postoperative scarring after facial contouring surgery. Based on an accurate understanding of the anatomical structures within the oral cavity, problems caused by multiple surgery due to inflammatory complications after a facial contouring surgery, including scarring, discomfort during mouth and cheek movements due to loss of oral vestibule, trismus, alveolar bone exposure, and gingival recession, were resolved with a single surgery. When performing intraoral surgery, it is necessary to understand the meaning and importance of vestibule and perform incision and suturing to minimize the shallowing of vestibule. In cases involving vestibule loss, appropriate techniques should be selected to ensure restoration of vestibule.
