Morphological assessment of the soft palate and a possible corelation with obstructive sleep apnea – A digital cephalometric study

Smruthi Valambath, Prabhath Ramakrishnan.

Abstract
Background: The available literature on the different morphologies of the soft palate is extremely scarce and has never been classified in an Indian population. We aim to study a corelation between different velar morphologies and probe variations with age, gender, and morphometric assessment based on the length and width. The present study also explores a possible link between snoring and particular velar morphologies as an indicator for the early diagnosis of obstructive sleep apnea syndrome (OSAS).

Aims and Objectives: (1) To assess the various velar morphological varieties in an Indian population, (2) most prevalent velar patterns according to gender predilection, (3) most prevalent velar patterns according to the age (adult >18 years and pre-adult <18 years), (4) assessment of the length and width of the soft palate, and (5) assessment of predilection for sleep apnea by comparing snoring with particular morphological variants.

Materials and Methods: Lateral cephalograms were obtained from 299 normal individuals whose age ranged from 5 to 85 years after obtaining clearance from the Institutional Ethical Committee. The velar morphology was classified, and the possibility of a corelation to gender, age, and the length and width of the soft palate was assessed. A snoring questionnaire was given to the relatives of the patients to assess the corelation between it and any particular velar morphology.

Results: Velar morphology was classified into six types, and we propose an indeterminate type as Type 7 in the classification. The results showed no corelation between particular velar morphologies and age or gender but showed a positive corelation between snoring and Type 6, Type 5, and Type 1 palates.

Conclusions: The study corroborates the classification suggested by earlier investigators. No significant association was noted with particular velar morphology and age/gender. However, a significant increase in length with respect to Type 5 was noted. The present study for the 1st time in literature derived a positive corelation between snoring and particular velar morphologies (Type 6, Type 5, and Type 1 palates) which may be of use as an early indicator for the early diagnosis of OSAS.
