Causes of Reoperation Consultation and Clinical Review of Actual Reoperation After Previous Orthognathic Surgery

Abstract

Objective: To investigate the causes of reoperation consultation, and the actual percentage and procedures of reoperation after previous orthognathic surgery. Methods: The samples consisted of 30 patients who visited our clinic for reoperation consultation from October 2015 to September 2021 (6 males and 24 females; mean age at reoperation consultation, 28.4 y). Patient’s causes of reoperation consultation were divided into “esthetic dissatisfaction,” “airway changes,” “temporomandibular disorders,” “uncomfortable occlusion,” and “other complications”. In terms of esthetic dissatisfaction, the more detailed esthetic problem was evaluated by the clinical chart, facial photographs, and radiographs. In patients who actually underwent reoperation, the actual percentage and procedures of reoperation were investigated. Results: The most prevalent causes for reoperation consultation were “esthetic dissatisfaction” (n = 21, 70.0%), followed by “airway changes” (n = 11, 36.7%), “uncomfortable occlusion” (n = 8, 26.7%), “other complications” (n = 5, 16.7%), and “temporomandibular disorder” (n = 4, 13.3%). Less than half of patients actually underwent reoperation (n = 13, 43.3%). Actual reoperation procedures included minor revision surgery, reconstruction surgery, or complete reoperation according to the patient’s need. In case of complete reoperation, more accurate and predictable results were obtained by using virtual surgical planning, customized surgical guides, titanium surgical plates made with computer-aided design and computer-aided manufacturing technique, and a 3-dimensional printing method. Conclusion: It is important to communicate with patients about expectations for facial esthetic improvement by orthognathic surgery for obtaining the patient’s postoperative satisfaction.
