Architecture of the Musculus Uvulae- A Review

Abstract

The architecture of the musculus uvulae is subject to controversy, especially with regard to its crucial role in maintaining the morphology of the cleft palate, and its involvement in surgical procedures of palate repair. Its functional role in the closure of the velum and elevation of the same leading to voice changes are also an element of debate. The fate and orientation of its muscle fibres and its reinforcement with other related muscles of the palate raise concerns with regard to its functional role. Its positioning in the soft palate would give us an insight on the exact role played by this muscle in velopharyngeal closure. Its nerve supply also remains shrouded by various theories without conclusive evidence. Hence, this review aims to highlight its morphological role for the same.
