We have studied 41 patients with classic submucous cleft and 32 cases with occult submucous cleft. Both groups have the same anatomic abnormality that leads to velar dysfunction-the insertion of the palate muscles onto the hard palate rather than onto the midline soft palate raphe. However, the occult submucous cleft palate does not have the classic triad of bifid uvula, hard palate bony notch, and furrow in the midline of the soft palate. Characteristic facial features, cephalmetric x-rays, and cine voice studies can help make a presumptive diagnosis of occult submucous cleft palate. Surgical management includes a diagnostic palate exploration to identify muscle configuration followed by levator muscle sling reconstruction, palate pushback, and pharyngeal flap. Excellent speech results are obtained except with patients having palate paresis.
我们研究了41例典型黏膜下腭裂患者和32例隐性黏膜下腭裂患者。两组具有相同的导致腭功能障碍的解剖学异常——腭肌附着于硬腭而非中线软腭缝。然而，隐性黏膜下腭裂没有典型的双裂悬雍垂、硬腭骨切迹和软腭中线沟三联征。特征性面部特征、头影测量X线片和动态语音研究有助于对隐性黏膜下腭裂做出初步诊断。手术治疗包括诊断性腭探查以确定肌肉结构，随后进行提肌吊带重建、腭后推和咽瓣手术。除了腭麻痹患者外，均取得了良好的语音效果。
