Morphological classification and velopharyngeal function analysis of submucous cleft palate patients / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To enhance the accuracy in diagnosis and management of submucous cleft palate via a thorough analysis of its anatomical and functional details.</p><p><b>METHODS</b>Two hundred seventy-six submucous cleft palate cases from 2008 to 2014 were retrospectively investigated. Subgroup analysis were performed on the basis of preoperative velopharyngeal function, palatal morphology, cleft lip concurrence, and patient motives for treatment.</p><p><b>RESULTS</b>Among the included cases, 96 (34.78%) were presented as velopharyngeal competence (VPC), 151 (54.71%) as velopharyngeal insufficiency (VPI), and 29 (10.51%) as marginal VPI (MVPI). Eighty cases (28.99%) also demonstrated cleft lip deformity, and 196 cases (71.01%) were merely submucous cleft palate. Compared with patients with submucous cleft palate only, those with cleft lips exhibited higher rates of complete velopharyngeal closure. The pathological spectrum of submucous cleft palate varied significantly. Only 103 (37.32%) cases met all the three diagnostic criteria proposed by Calnan.</p><p><b>CONCLUSIONS</b>Given that the velopharyngeal closure rate varies among the subgroups, the factors analyzed in this study should be considered in the personalized manage-ment of submucous cleft palate.</p>
