Background: Obstructive sleep apnea (OSA) is a condition of partial or complete upper airway obstruction leading to increased resistance to airflow and potential cessation of breathing for 10 seconds or more. The causes of OSA include factors related to the upper airway anatomy, for instance, narrow airway space, relative mandibular retrognathia, increased tongue volume, and enlargement of palatine or adenoidal tissue. Aim of the study: To compare cephalometric analysis of patients with obstructive sleep apnea and healthy subjects. Materials and methods: The study was conducted in the Department of Orthodontics and Dentofacial Orthopedics of the Dental institution. For the study, we included patients with known history of regular snoring. An informed written consent was obtained from the participating subjects. Patient with history of craniofacial injury either hard tissue or soft tissue injury, history of orthodontic treatment, or with systemic diseases were excluded from the study. A total of 80 patients with history of snoring were selected. 80 healthy subjects were selected as controls. Results: In the present study, 80 subjects with history of snoring and 80 controls were included. We evaluated that length of hard palate was 52.33 mm for OSA patients and 50.41 mm for controls. Distance of gonion from point B was 76.12 mm for OSA patients and 79.13 mm for controls. The findings were statistically non-significant. Conclusion: Within the limitations of the present study, it can be concluded that difference of pharyngeal dimensions in OSA patients and controls was non-significant.
