Abstract
INTRODUCTION: Otorrhea is a common sequela after myringotomy with tube placement (MTP). The purpose of this study was to identify any significant relationship between passive tobacco exposure and the development of post-tympanostomy tube otorrhea.
METHODS: Retrospective chart review was performed on 774 cases of patients who underwent MTP by a single surgeon at a tertiary pediatric hospital from 2012 to 2014. Patients with multiple medical comorbidities, craniofacial anomalies, syndromes and those over 12 years of age were excluded. Multivariate logistic regression analysis was performed to determine if there was a relationship between risk factors (including tobacco exposure, age, pre-operative diagnosis, operative findings and duration of follow-up) and the development of post-tympanostomy tube otorrhea.
RESULTS: One hundred and ninety-one patients (average age of 1.92 years) were included. Overall, 16.8% of patients (32/191) had exposure to tobacco smoke. Of patients with passive smoke exposure, 65.6% (21/32) developed otorrhea, as compared to 45.3% (72/159) of those without tobacco exposure. Passive exposure to tobacco smoke by (OR = 2.307; p = 0.009; 95% CI, 1.734-6.028) and younger age (p = 0.012; 95% CI, 0.602-0.938) were associated with increased risk for otorrhea.
DISCUSSION: This study suggests that in a cohort of patients undergoing MTP, passive exposure to tobacco smoke significantly increases the risk of developing post-operative otorrhea. This information is valuable to include in parental preoperative counseling regarding tympanostomy tube placement.
