Evaluation of the associations between maxillary sinus dimensions and adenoid hypertrophy using multislice computed tomography.

INTRODUCTION

Adenoid hypertrophy is especially common in childhood, raising the concern that such growth might affect maxillary sinus volumes during the developmental period. This study evaluated the developmental relationships between maxillary sinus volumes and adenoid hypertrophy via computed tomography.

MATERIALS AND

METHODS

It was examined computed tomographic images of 118 individuals: 61 boys and 57 girls. The participants were divided into a healthy control group (n = 59) and an experimental group (with adenoid hypertrophy) (n = 59). Raw data were recorded in DICOM format and analysed using the ITK-SNA algorithm; it was measured the right, left, and total maxillary sinus volumes and adenoid tissue sizes.

RESULTS

It was found significant between-group differences in the three maxillary sinus volumes and adenoid tissue dimensions (linear maximum anterior and posterior depth; maximum upper and lower height, and maximum width to the right and left) (all p<0.001). On the contrary, there was no significant difference according to sex in terms of either maxillary sinus volumes or linear adenoid tissue measurements. Maxillary sinus volumes increased significantly according to age in both groups.

CONCLUSION

Adenoid hypertrophy decreases the maxillary sinus volumes, regardless of sex. The impacts of adenoid growth on maxillary sinus aeration and sinus disease should be further investigated.
