Lai D, et al. - This paper encompassed an exploratory analysis of the efficacy and reliability of acoustic rhinometry (AR) in determining the benefits from adenoidectomy in children with otitis media with effusion (OME). A good clinical association was illustrated with findings of nasal endoscopy, by the AR parameters. Hence, it could be beneficial in the assessment of candidacy for surgical adenoidectomy among children with OME, especially in whom preoperative nasal endoscopic examination was not feasible. The variations occurring within the nasopharyngeal passage before and after adenoidectomy could be disclosed by AR.
