Sommerlad-Furlow法修复腭裂术后儿童上颌牙弓发育影响因素的研究

ObjectiveThis study aims to investigate factors influencing dental arch development in patients aged 0-6 years with cleft palate after Sommerlad-Furlow (SF) palatoplasty.MethodsA total of 183 patients who underwent primary SF repair for cleft lip and palate before 18 months of age were included. Follow-ups were conducted at different ages, and digital dental casts of the maxillary dental arch were obtained using 3-matic Research 12.0 software. The length and width of the dental arch and palate were measured to explore developmental changes in the maxillary dental arch of the patients after the procedure. The study also investigated the influence of gender, age, cleft palate type, and relaxation incision on maxillary dental arch development.ResultsAfter SF, maxillary dental arch measurements showed statistically significant differences between children aged 0-2 years and those aged 3-6 years (P<0 .05). however, no statistically significant differences were observed among different age groups within the 3-6 years range. statistically significant differences were detected between males and females, with males having greater width of the posterior dental arch and palate (P=0.001) and shorter length of the anterior dental arch and entire dental arch (P<0 .05). the unilateral cleft lip and palate group had shorter dental arch length (P<0 .01) and wider posterior palate (P<0 .01) than the cleft palate only group. maxillary dental arch measurements had no statistically significant differences between groups with or without a relaxing incision.ConclusionGender and age influence the width of the maxillary dental arch in children aged 0-6 years after SF, while age and cleft palate type affect dental arch length.
