The Effect of Long-Term Follow up on Outcome of Pediatric Endoscopic Sinus Surgery

ABSTRACT

BACKGROUND AND OBJECTIVES: Chronic pediatric sinusitis continues to be a challenging problem to otolaryngologists and has been reported to show worse prognosis than that of adults. However, most studies were performed with short-term follow-up. In this study, we aimed to assess the clinical outcome of pediatric endoscopic sinus surgery (ESS) with a longer follow-up and to determine the effect of age on postoperative outcome. SUBJECTS AND METHOD: A retrospective analysis was performed on pediatric patients than 15 years with ESS younger from 2005 to 2014 in a tertiary referral hospital. All patients completed a questionnaire regarding symptoms before to from 1 to 9 years after surgery. Telephone survey was performed to evaluate symptoms including nasal obstruction, nasal discharge, PND, and headache at 1 to 9 years after surgery. RESULTS: Seventy-one pediatric patients with bilateral chronic sinusitis were treated with ESS. They showed gradual symptom improvement from 5 year after surgery for the following nasal obstruction (p=0.032), PND (p=0.005), and headache (p=0.048). However, there was improvement in rhinorrhea after 9 years (p=0.042). In addition, when analyzed in terms of age, the outcome was poor in children younger than 13 years (p=0.003) compared with the older age group. Multivariate analysis showed that preoperative nasal obstruction was dependent on AR, and postoperative symptoms were dependent on presence of AR and involuntary smoking. Nasal discharge was dependent on presence of AR and involuntary smoking preoperatively and postoperatively. These suggest the importance of AR and involuntary smoking as risk factors for prognosis. CONCLUSION: Chronic pediatric sinusitis showed gradual improvement after ESS and should be more carefully monitored on a long-term basis. We should keep in mind that long-term follow-up is needed for pediatric ESS cases.
