摘要
Acquired isolated palatal palsy is a rare disease.It is commonly seen in children.It usually presents with acute onset nasal regurgitation of fluids,rhinolalia,and palatal asymmetry.Many causes of this disease,such as infections,trauma,tumor,and brainstem lesions,etc.,have been reported.However,the most plausible explanation is immunological/ischemic damage to the affected nerve.After ruling out major potential causes of this disease,the damage is often considered to be idiopathic in nature.This disease has a benign self-limiting course with excellent recovery.In accordance with a hypothesized immunological basis for this condition,treatment with steroids results in significant improvement in its clinical features.
