Abstract
OBJECTIVE: The aim of this study was to investigate the developmental relationship between adenoid tissue volume and mastoid air cell volume, using a 3D reconstruction technique. STUDY DESIGN: Cross-sectional retrospective study. SUBJECTS AND METHODS: Multislice computed tomography (MSCT) images were obtained using three-dimensional (3D) reconstruction and volume-rendering techniques (VRT). The subjects were 63 boys and 37 girls, 3-16 years of age. The volumes of bilateral mastoid air cells and adenoids marked in axial-coronal-sagittal planes were calculated. The patients were grouped into three categories according to adenoid tissue volume, total mastoid volume (TMV), and age. RESULTS: No significant difference was noted between the right mastoid volume (RMV) and the left mastoid volume (LMV) or between age and sex (p=0.368; p=0.549; p=0.454). The incremental increase in adenoid tissue volume did not correlate with TMV (r=-0.161, r=-0.279, r=0.015). The incremental increase in TMV did not correlate with the volume of adenoid tissue (r=0.024, r=0.148, r=0.017). CONCLUSIONS: No significant correlation was obtained between the incremental increase in adenoid tissue volume and TMV or the incremental increase in TMV and adenoid tissue volume. There does not seem to be a developmental relationship between adenoid tissue volume and TMV.
