1009 Surgery: Problem and Solution. Temporomandibular Joint Reconstruction For Treating Obstructive Sleep Apnea After Cosmetic Surgery

Abstract

Abstract Introduction Orthognathic surgery is often considered for the treatment of obstructive sleep apnea (OSA); however, in some circumstances, specific interventions may precipitate OSA. Report of case(s) A 34 year-old female presented with complaints of snoring and fragmented sleep. She had undergone bimaxillary osteotomy and mandibuloplasty for cosmetic reasons outside of the country in 2019. Prior to the surgery, she was asymptomatic and did not snore. Post operatively, she developed snoring, witnessed apneas, fragmented sleep, and daytime sleepiness. A home sleep apnea test revealed severe obstructive sleep apnea with Respiratory Event Index (REI) 66.4/hr. She was initially treated with Positive Airway Pressure (PAP) while seeking oral surgery consultation. PAP via nasal mask was initially effective with residual Apnea Hypopnea Index (AHI) of 3/hr., but the patient developed difficulty tolerating PAP due to aerophagia, nausea, and eructation, despite limiting pressures to 5-7cm H2O. In 2022, the patient successfully underwent temporomandibular joint (TMJ) reconstruction with total joint prosthesis, TMJ fat grafting, bilateral coronoidectomy, maxillary osteotomy with bone plate and grafting, and partial inferior turbinatectomy. She reported resolution of snoring and significant symptomatic improvement after surgical revision. Repeat home sleep apnea testing 1 month after the surgery revealed REI 0.6/hr. Conclusion This case illustrates the potential for development of OSA following orthognathic surgery. Patients and providers should be aware of this potential complication when pursuing surgical intervention. Support (if any)
