Surgical treatment for facial asymmetry patients is one of the most challenging one for surgeons not because the surgical technique for this type of deformity is difficult but because the postoperative care of dental occlusion needed for this type of deformity patients varies considerably from patient to patient. The problems include whether intermaxillary fixation should be used or not, how long it should be maintained if necessary, and what type of occlusal wafers provides a good result according to relapse.<BR>We experienced a case that a patient of facial asymmetry whose deformity was corrected by Le Fort I and bilateral mandibular rami ostotomies presented relapse due to the tension of the suprahyoid muscles immediately after surgery.<BR>Intermaxillary fixation with an interocclusal wafer pivoting at the mandibular molar region of the right side for a week and seven-week period of traction with elastics between arches with this wafer except during meals resulted in a good dental condition.
