Demographic data on the characterization of oral clefts in Malaysia

ABSTRACT

The aim of this study was to investigate current epidemiology of several types of oral clefts among the patients receiving treatment at two tertiary care hospitals, namely University Malaya Medical Centre [UMMC] Kuala Lumpur, and Hospital Kota Bharu / Hospital Raja Perumpuan Zainab II [HKB/ HRPZII] Kelantan. This study evaluated the records of 526 cleft lip and palate [CLP] patients with or without additional malformations, who came for treatment during 2003 to 2007. Of the total 526 patients registered in the study hospital records during the study period, 338 were from HKB/ HRPZ II and 188 from UMMC. Majority 86.7% of these patients were in the age group females and 43% males were affected by oral cleft. Out of the total patients, 77.8% were CLP, 13.5% were cleft palate [CP], and 8.7% were cleft lip [CL] patients. Moreover 57.2% patients were with unilateral cleft, 32.7% were left sided and 24.5% were right sided. Total 42.8% patients were with bilateral oral cleft. To best of our knowledge this is the first reported multi-center study on CLP in Malaysia with regard to the proportion of different types of oral clefts
