Le Fort Ⅰ osteotomy for correction of malunioned maxilla

A 61 year-old male patient was transferred to us with a chief complaint of malocclusion and masticatory difficulty due to malunioned maxilla. The malocclusion was corrected by Le Fort Ⅰ osteotomy. The conclusions are as follows: 1. The cause of malocclusion was malunioned maxilla. 2. Total Le Fort Ⅰ osteotomy was used to correct malunioned maxilla. 3. For rigid fixation and reducing the intermaxillary fixation period, metal plates were used. 4. Masticatory problem of the patient was solved. And there were no postoperative complications and evidence of relapse found.
