Significance of Adenoid Nasopharyngeal Ratio in the Assessment of Adenoid Hypertrophy in Children

The aims of this study are to find out the significance of adenoid nasopharyngeal ratio obtained from lateral X-Ray of nasopharynx to decide on the option of surgical treatment of adenoid and to correlate the symptoms with the relative size of adenoid in the nasopharynx. This prospective study was done on 100 children who presented with bilateral nasal obstruction from 4- 12years of age. Radiological assessment of lateral radiograph of nasopharynx was done. Mean adenoidal depth and mean nasopharyngeal depth were calculated as per Yusuf et al method. Mean ANR was calculated by dividing adenoidal depth by nasopharyngeal depth. There was significant increase in adenoid size during 7-9 years and decrease in 10-12 years, the nasopharyngeal depth increased as age progressed. It was concluded that ANR > 0.7 are the candidates for adenoidectomy.
