Effects of adenoidectomy on sinusitis.

Effect of adenoidectomy on sinusitis was investigated in 78 children (aged 5 to 7) with adenoid vegetation, sinusitis and otitis media with effusion. After a 6 month period, improvement of the sinusitis was observed in 25 of the 45 children (56%) in the adenoidectomized group, and only in 8 of the 33 children (24%) in the non-adenoidectomized group. This was statistically significant in the adenoidectomized group (mean 2 = 7.65, p < .01). Through nasopharyngeal endoscopy in the adenoidectomized children in the 6 months following surgery, we noted decreased evidence of infection and/or inflammation. These findings may indicate that adenoidectomy is effective for sinusitis in children.
