Abstract

Objective: Adenoid hypertrophy (AH) has been identified as a cause of otitis media with effusion (OME), which is the most common cause of childhood hearing loss. Indeed, there may be other upper airway-related predisposing factors such as, location of the adenoid, accompanying tonsillar hypertrophy (TH) and nasal septal deviation (NSD) for the development of OME. In this study, we aimed to evaluate the associations between the upper airway physicals and OME with auditory functions.& nbsp;Methods: Eighty-six ears of 43 children, aged 3-11 years were included in this prospective clinical study. Findings of otolaryngologic examinations were noted. Data of pure tone audiometry (PTA), traditional tympanometry (TT) and wideband tympanometry (WBT) parameters were collected. Cluster analysis was performed to the following variables: age, sex; the adenoid choana percentage (ACP), the presences of adenoid around torus tubarius (AATT), TH, NSD and OME; peak pressure (PP) values on TT, resonance frequencies (RF) on WBT, ambient pressure absorbance ratios (APAR) and PTA hearing thresholds.& nbsp;Results: Two groups of ears revealed by clustering; cluster-1 (n = 46) and cluster-2 (n = 40), at the similarity level of 0.662. The presences of AH, AATT, OME and the medians of ACP, PP, RF, WBT APARs at all frequencies except 5656 Hz and 8000 Hz, all PTA thresholds were significantly different between two clusters (p < 0.05). The lower WBT APARs and higher PTA thresholds were associated with higher levels of ACP and higher frequencies of the presence of AATT and OME in cluster-1.& nbsp;Conclusion: There are associations between AH, AATT and OME together with decline in hearing and SEA. Whereas, TH and NSD are not related to the formation of clusters and they are insignificant factors. (C)& nbsp;2021 Japanese Society of Otorhinolaryngology-Head and Neck Surgery, Inc.
