OBJECTIVE: To determine correlation between pharyngeal airway space and sagittal skeletal malocclusions.
METHODOLOGY:
Data was collected using pre-treatment records including pre-treatment lateral cephalograms of 54 orthodontic patients. Patients from both gender were included. The age group of selected patients was 15-25 years, Patients belonging to Pakistani ethnicity were included to avoid selection bias. Sagittal skeletal malocclusion was measured by ANB angle to group the skeletal Class I, II and III subjects (ANB=0-4°, ANB > 4° and ANB <0 respectively). Upper pharyngeal space and Lower Pharyngeal space was measured. This cross sectional study was conducted in Orthodontic OPD at Karachi Medical and Dental College, from August 2019 to March 2020.
RESULTS:
The obtained data showed strong negative correlation between ANB angle and upper pharyngeal space whereas moderately negative correlation between ANB angle and lower pharyngeal space.
CONCLUSION:
Upper and lower pharyngeal widths were influenced by Sagittal malocclusion.
KEYWORDS:
Pharyngeal airway space, Sagittal skeletal malocclusion, Obstructive sleep apnea, Sleep disordered breathing, ANB.
