Clefts of lip (CL), palate (CP), or both (CLP) are the most common orofacial congenital malformations found among live births, accounting for a large number of head and neck anomalies. To date, little is known regarding the epidemiology and pattern of orofacial clefts in Nepal. The objectives were to know the frequency and pattern of orofacial clefts in Eastern Nepal and compare with different parts of the world.
A retrospective study was conducted at B P Koirala Institute of Health Sciences to identify all children with orofacial clefts who were treated during a period of five years. Cleft lip and/or palate records were obtained from patient files in the Hospital's Medical Record Department. Age at presentation, sex, region of origin, type and laterality of the cleft were recorded.
A total of 398 orofacial cleft cases were seen during the period. Isolated cleft lip (CL) was the most common cleft type followed closely by cleft palate (CP).
The distribution of clefts by side showed a significant preponderance of the left side followed by the right and bilateral sides.
唇裂（CL）、腭裂（CP）或唇腭裂（CLP）是活产儿中最常见的口腔面部先天性畸形，占大量头颈部异常病例。迄今为止，关于尼泊尔口腔面部裂隙的流行病学和模式知之甚少。目的是了解尼泊尔东部口腔面部裂隙的频率和模式，并与世界不同地区进行比较。
在BP柯伊拉腊健康科学研究所进行了一项回顾性研究，以确定在五年期间接受治疗的所有口腔面部裂隙患儿。唇裂和/或腭裂记录来自医院病历科的患者档案。记录就诊时的年龄、性别、籍贯、裂隙类型和侧别。
在此期间共观察到398例口腔面部裂隙病例。单纯唇裂（CL）是最常见的裂隙类型，紧随其后的是腭裂（CP）。
按侧别分布的裂隙显示左侧明显占优势，其次是右侧和双侧。
