Tympanomastoidectomy versus parenteral antibiotic therapy for pediatric otorrhea.

Objective: To evaluate the efficacy of tympanomastoidectomy versus parenteral antibiotic therapy for otorrhea as a result of chronic suppurative otitis media (CSOM) without cholesteatoma in the pediatric population.

Methods: A retrospective review of 221 patients treated for otorrhea at a tertiary academic pediatric hospital was performed to evaluate the impact of tympanomastoidectomy versus parenteral antibiotic therapy on resolution of otorrhea. Inclusion criteria were age 0-18 years, prior treatment with otic and/or oral antibiotic, prior history of tympanostomy tube placement for recurrent otitis media, history of otorrhea, treatment with tympanomastoidectomy or parenteral antibiotic therapy, and follow-up of at least 1 month after intervention. Time to resolution was compared between the two modalities adjusting for age, bilateral ear disease status, and comorbidities using a Cox proportional hazard model.

Results: Eighty-three ears from 58 children met the inclusion criteria. Ears that initially underwent tympanomastoidectomy had a significantly shorter time to resolution of symptoms (median time to resolution) 9 months (95 % confidence interval CI: 6.2-14.8) vs. 48.5 months (95 % lower CI 9.4, p = 0.006). On multivariate analysis, however, only bilateral ear disease status was independently associated with time to resolution of symptoms (hazard ratio 0.4, 95 % CI 0.2-0.9, p = 0.03). There was no statistically significant difference in the rate of treatment-related complications when comparing tympanomastoidectomy to parenteral antibiotic therapy (p = 0.37).

Conclusion: When adjusting for age, bilateral ear disease status, and comorbidities, there does not appear to be a significant difference in time to resolution of symptoms when comparing parenteral antibiotic therapy to tympanomastoidectomy. An informed discussion regarding risks and benefits of each approach should be employed when deciding on the next step in management for patients with CSOM who have failed more conservative therapies.
