- Abstract: Objective To examine the characteristics of the prevalence of congenital cleft lip with/without cleft palate in the ethnic Tibetan population and to provide support for the precise prevention and treatment of cleft lip with/without cleft palate in the Tibetan population.Methods The clinical data of Tibetan patients with cleft lip with/without cleft palate were collected and the clinical characteristics of the patients were analyzed.The patients'age ranged from 2 months to 51 years old.All the subjects were admitted to West China Stomatology Hospital,Sichuan University for the treatment of cleft lip with/without cleft palate between January 2016 and August 2023.Most of the subjects came from Sichuan Province and the Tibet Autonomous Region.Results A total of 1 051 patients were enrolled and children aged under 12 months(460 cases)accounted for the largest proportion.Among the subjects,383 had cleft lip only(36.44%),140 had cleft palate only(13.32%),and 528 had cleft lip with cleft palate(50.24%).The male-to-female ratios of patients with cleft lip only(0.99∶1),cleft palate only(0.54∶1),and cleft lip with cleft palate(1.67∶1)exhibited significant differences(P＜0.001).However,there was no significant difference in the male-to-female ratio in patients with cleft lip only or those with cleft lip with cleft palate when the subjects were divided into two groups according to whether they had unilateral or bilateral cleft lip with/without cleft palate.Most of the patients with bilateral cleft lip were female,while most of the patients with unilateral cleft lip and unilateral or bilateral cleft lip with cleft palate were male.The unilateral cleft lip with/without cleft palate was located predominantly on the left side.Syndromic cleft lip with/without cleft palate accounted for 3.43%of all the cases and the most common concomitant deformity was congenital heart disease.3.81%(40 cases)of the patients had a family history.In the patients with cleft lip only and those with cleft palate only,the proportion of patients having parents with corresponding phenotypes was higher than those of other phenotypes of cleft lip with/without cleft palate.Regarding the birth time distribution of the children with cleft lip with/without cleft palate,Spring saw the highest number of births of these children(311 cases,29.59%),while Winter saw the lowest number of births(231 cases,21.98%).Conclusion The cases of cleft lip with/without cleft palate in the ethnic Tibetan population are predominantly cleft lip and palate.Unilateral cleft lip only or cleft lip with palate is predominantly located on the left side.Lip disease phenotypes may be more heritable.
