To evaluate the impact of bimaxillary osteotomy on upper airway metrics and patient-reported sleep quality in patients with cleft lip and palate.
Design
Retrospective cohort study involving Class III patients.
Setting
A specialized craniofacial surgery center within a tertiary care institution.
Patients/Participants
Eight patients with unilateral cleft lip and palate were included, undergoing pre- and postoperative assessments (≥1 year after surgery).
Interventions
Bimaxillary orthognathic surgery, including mandibular setback and maxillary advancement. Cone-beam computed tomography (CBCT), nasopharyngoscopy, and polysomnography were performed, along with sleep quality questionnaires (Epworth and Berlin scales).
Main outcomes
Upper airway (UA) volume and minimum cross-sectional area assessed via CBCT; apnea–hypopnea index (AHI) from polysomnography; airflow analysis and sleep quality assessments.
Results
No significant changes were observed in UA volume or minimum cross-sectional area, including the oropharynx and hypopharynx regions. Similarly, there were no clinical repercussions on sleep, with AHI remaining stable between pre- and postoperative assessments.
Conclusions
In this cohort of 8 patients with unilateral cleft lip and palate, bimaxillary osteotomy did not result in significant changes in upper airway metrics or patient-reported sleep quality.
