Aim of this study is to compare the palatine tonsil (PT) volume measured with transcervical ultrasonography (TCU) in children with the actual volume to research the correlation with tonsillectomy indications. This prospective study included a total of 67 children, 37 boys and 30 girls, aged from 3-17 years who underwent bilateral tonsillectomy. Cases were divided into two groups based on tonsillectomy indications as chronic tonsillitis (Group 1) and obstructive sleep apnea syndrome (OSAS) (Group 2). The sonographic volume was measured with a 4.8-11.0 MHz linear transducer before tonsillectomy, while the actual volume was measured with the water displacement method. The correlation between both volume values was researched. Partial Correlation test was used to analyze correlations between variables after analysis of SPSS 22.0 program and age and gender factors. The mean ages in Groups 1 and 2 were 115.83±53.2 and 120.6±54.7 months, respectively. The actual and sonographic tonsil volumes in Group 1 were 2.03±0.82 ml and 2.22±0.85 ml (p=0.093), in Group 2 were 5.19±0.83 ml and 5.36±1.06 ml (p=0.074), respectively. In both groups the sonographic volume was correlated with the actual volume (r=0.788 and 0.829, respectively). The measured volumes with both methods were higher in Group 2 (p
