粘膜下腭裂又名腭隐裂,在腭裂中较为少见。我院自1975～1981年共收治6例,由于本病的发病率,临床表现、诊断、治疗等报道较少,临床上易于误诊及处理不当,有必要加以讨论。病例报告摘要男、女各3例,就诊年龄自7～35岁,平均16.7岁,其中施行手术4例,平均年龄11.2岁,两者均明显高于腭裂患者。 Submucosal cleft palate, also known as palatal crack, is relatively rare in the cleft palate. In our hospital from 1975 to 1981 were treated 6 cases, due to the incidence of the disease, clinical manifestations, diagnosis, treatment and other reports less clinically misdiagnosed and handled properly, it is necessary to be discussed. The case report summary male and female 3 cases, the treatment age from 7 to 35 years old, an average of 16.7 years, of which 4 cases were performed surgery, the average age of 11.2 years, both were significantly higher than the cleft palate patients.
