Materials and Methods: Twenty-six Class Ill adult patients treated with bimaxillary surgery were included in the study. Cephalometric records were taken before surgery (T1) and 5 months (T2), 1.4 years (T3), 3 years (T4), and 5 years (T5) after surgery. Results: There was no significant relapse in skeletal parameters. Overjet was significantly reduced between T4-T3 time intervals (P < .01). There were significant increases in Sn-HR, ULA-HR, LLA-HR, B-B<^> (P < .01), and B<^>-HR (P < .05) between T4-T3 time intervals. There was no significant change in the soft tissue parameters between T5-T4 time intervals. Conclusion: Soft tissue vertical relapse occurs in skeletally stabile Class Ill bimaxillary surgery patients in the first 3 years after surgery.eninfo:eu-repo/semantics/openAccessBimaxillary surgery; Soft tissue; Class IIIArticle10.2319/062214-449.1854631637252719552-s2.0-84937060816Q1WOS:000357242200014Q2
