This study investigated the effects of Furlow palatoplasty on children with submucous cleft palate (SMCP) and identified surgical indications by comparing SMCP and control patients. Twenty-three SMCP children (average age 28.9 months) who were nonsyndromic and underwent surgery between April 2010 and December 2016 were included. Facial computed tomography (CT) was performed preoperatively and at least 1 year postoperatively after a language test. Facial CT measurements were taken for 140 children aged 0–6 years without deformities (control group). Later surgery was associated with more severe nasality. In the coronal view, the difference in the maxillary tuberosity before and after surgery was 3.8 mm (p < 0.05). The height and width of the palatal arch (HNP and WNP) were well maintained (p > 0.05), whereas the angle of the levator veli palatini muscle (ALM) increased (p < 0.05). The nasopharynx was close to normal postoperatively. The distance between the medial pterygoid plates, the HNP, and the WNP were larger in SMCP patients preoperatively (p < 0.05), but these differences disappeared after surgery (p > 0.05). The ALM in SMCP patients was narrower preoperatively, but became flatter postoperatively (p < 0.05), indicating the repositioning of the levator muscle, with improvement of the velopharyngeal function. Furlow palatoplasty is indicated if the HNP and WNP values are larger, and the ALM value is less, in patients with SMCP than in those without.
