The association between middle ear disease and abnormal pathway of the levator veli palatini muscle was investigated by otological and endoscopic examination in patients with submucous clef palate (SMCP).The characteristics of middle ear diseases of SMCP patients were similar to those of cleft palate patients, suggesting that the morphology and function of the eustachian tube system are similar in those two types of cleft palate.In SMCP patients after palatoplasty, middle ear disease was less common in patients with levator muscle sling formation than in those without muscle sling formation. The abnormal pathway of the levator muscle was thought to have some effect on the middle ear. Some patients without muscle sling formation, however, had no middle ear disease, suggesting that other anatomical anomalies of the eustachian tube system also play an important role in the high incidence of middle ear disease in cleft palate patients.
