Measurement of Normal Thyroid Gland Volume in School Age Children using Ultrasonography

Abstract

This is a retrospective cross sectional study which was done during the period from August to October 2016, at Surgical Diagnostic Center, Kassala state - Sudan. The study discussed measurement of normal thyroid volume in school age Sudanese using Ultrasonography and correlate this volume with age, gender, height and weight. A total of “64” subjects were selected randomly; all those patients have age ranged from 6 to 18 years and with normal thyroid gland. Any subject had age fewer than 6 or above 18 years or had abnormal thyroid was excluded from this study. All patients were subjected to be examined by U/S scanning using Mindray M7 color Ultrasound Machine with 10 MHz probe. Ultrasound Scanning was performed for all subjects to evaluate thyroid dimensions and volume. Data was collected using a data collecting sheet and in data analysis the author uses the cross tabulation, linear regression and discriminates analysis. Study shows that the mean values for body characteristic height and weight were 138.07±17.6 ,33.83±18.8 and 136± 16.9 ,33.35±16.05 for male and female respectively. The overall mean thyroid gland volume combined for both lobes and sex obtained from this study was 3.96±1.28 cm3. Study concluded that; there was a statistical significance of difference in right and left lobes measurements due to age and body mass index. Study also revealed that; the right lobe was larger in size than left one and female measurements show higher average size of two lobes than in males. Study recommended that; All people specially child and those who have reduction of Iodine intake were advised to do U/S scanning routinely to exclude the presence of any abnormality, because U/S is a cheep, safety and reliable..
