NORMAL VALUES OF UPPER CRANIOFACIAL SKELETAL MEASUREMENTS OF THAI PATIENTS IN UDONTHANI HOSPITAL BASED ON COMPUTED TOMOGRAPHY
Abstract
This study was performed to establish normal values of the upper craniofacial skeleton of 1026 Thai patients in Udonthani hospital using CT scan. The samples were collected from july 2006 to july 2007, age ranging from newborn to 82 years. The measurement values were divided into four age groups, for those under the age of 1 year, 1 year, morethan 1 year upto 17 years and more than 17 years in the last category. No comparison between genders in this study, except in the subjects with the age of more than 24 years and these increase gradually to adult sizes. The size of these measurement increase rapidly to about 85 % of adult sizes by the age of 5 years and then increases gradually to adult sizes. The ability of Computed Tomography (CT scan) to identify bony and soft tissue features makes it particularly useful for the management of craniofacial disorders. The normal values of the upper craniofacial skeleton of Thai patients in Udonthani hospital are useful for the accurate diagnosis and reconstructive surgery planning of Thai patients in Udonthani and Northeastern Thailand.
