The Developmental Relation between Adenoid Tissue and Paranasal Sinus Volumes in 3-Dimensional Computed Tomography Assessment

Objective. The aim of this study was to evaluate the developmental relationship between the volumes of paranasal sinuses and adenoid tissue by using a 3-dimensional (3D) reconstruction technique.

Study Design. Cross-sectional study.

Setting. Tertiary referral center.

Subjects and Methods. Multislice computed tomography (MSCT) images were obtained using 3D reconstructions and a volume-rendering technique (VRT) in 69 boys and 35 girls aged 3 to 16 years, and bilateral maxillary, frontal, and sphenoid sinus volumes, as well as adenoid tissue volume marked in axial-coronal-sagittal planes, were calculated. The patients were grouped in 3 categories according to adenoid tissue volumes, and comparisons were made.

Results. There was no significant difference between the right maxillary volume and left maxillary volume (P = .93). No significant difference was noted between the groups in terms of age and gender. There was no significant correlation between frontal, sphenoid, right and left maxillary, or total maxillary sinus volumes in all 3 groups of patients.

Conclusion. When classified according to adenoid tissue size, it was observed that increasing adenoid tissue volumes did not significantly affect the development of paranasal sinuses. Developmentally, there are no statistically significant correlations between the volumes of paranasal sinuses and adenoid tissues.
