OBJECTIVE: To investigate preoperative clinical findings of chronic otitis media (COM) in patients with Down and without (non-Down) syndrome.
STUDY DESIGN: Retrospective.
SETTING: Referral hospital, otolaryngology department.
PATIENTS: Patients with COM who underwent tympanoplasty were included. There were 10 ears of 8 patients (mean age, 14.9 yr) in the Down group and 44 ears of 41 patients (mean age, 14.7 yr) in the non-Down group.
MAIN OUTCOME MEASURES: Clinical characteristics, including the frequency of preoperative persistent otorrhea, cause of COM, and mastoid pneumatization (maturation), were compared between the 2 groups using clinical records and temporal bone computed tomography (CT).
RESULTS: Preoperative persistent otorrhea was more frequent in the Down group (60%) than in the non-Down group (27.2%; p < 0.05). Perforation due to tympanostomy tube insertion also occurred more frequently in the Down group (100%) than in the non-Down group (53.3%; p < 0.05). Mastoid pneumatization occurred significantly less in the Down group than in the non-Down group (p < 0.01). There was no significant difference in mastoid pneumatization regardless of the presence or absence of a past history of tympanostomy tube insertion in the Down group (p = 0.3, t test) unlike that in the non-Down group (p < 0.05, t test). All ears attained a dry condition with no perforated eardrums.
CONCLUSION: Frequent draining ear and extremely immature mastoid pneumatization, regardless of the presence or absence of a past history of tympanostomy tube insertion, were clinically important characteristics of COM in patients with Down syndrome.
