{Abstract}: BACKGROUND: Submucous cleft palate (SMCP) is a congenital anomaly characterized by the presence of Calnan's triad. However, in clinical practice, it is common for individuals to exhibit one or two anatomical abnormalities within the triad. Furthermore, the definition of SMCP has been diverse and ambiguous in literature. Therefore, this study aimed to analyze the correlation between anatomical abnormalities and development of velopharyngeal insufficiency (VPI).
METHODS: We conducted a retrospective analysis of 99 patients referred to our clinic for speech issues or anatomical abnormalities identified during routine oral examinations from January 2012 to June 2023. A single surgeon performed all physical examinations. We evaluated the presence of bony notch, zona pellucida, and bifid uvula, assigned a score to each abnormality, and analyzed their correlation with VPI. The correlation of each of the abnormalities with VPI development was examined, along with the relationship between the number of abnormalities and VPI.
RESULTS: Among the 99 patients, 27 were diagnosed with VPI. Only the bony notch had a significant correlation with VPI development. The incidence of VPI tended to increase with the presence of more anatomical abnormalities. VPI occurred in approximately 40% of patients exhibiting all three anatomical abnormalities.
CONCLUSIONS: The study findings highlight the importance of meticulous intraoral examinations in patients with SMCP and careful monitoring of patients with a bony notch or two or more anatomical abnormalities.
