ObjectivesLiterature is sparse on the development of obstructive sleep apnea (OSA) after anterior cervical spine surgery and includes few case reports. Our objective is to evaluate the role of anterior cervical spine surgery as a risk factor for developing OSA.MethodsA retrospective cohort study was performed utilizing the M157 subset of the PearlDiver national database. Two matched cohorts of patients were identified based on anterior cervical spine surgery using CPT codes. ICD-9 and 10 was used to identify patients who developed OSA within one year time frame in both the cohorts. Relative risk of OSA was calculated for the study and risk factors for developing OSA in the cohort of anterior cervical surgery were evaluated using logistic regression.ResultsThe 2 cohorts contained 277,475 patients each. The 1-year incidence rate of OSA in those who undergo anterior cervical spine surgery is 3.5% and is 3.1% in the control group. The relative risk of OSA in the surgery group is 1.13 times compared to the control. Multilevel cervical spine surgery and surgery performed for spondylosis had a higher risk of developing OSA.ConclusionsAnterior cervical spine surgery is associated with an increased risk of developing OSA within one year of surgery. Timely diagnosis and management of OSA in patients who underwent anterior cervical spine surgery can help prevent morbidity and improve quality of life (QOL).Copyright © 2024 Elsevier Inc.
