Comparative analysis of the outcome of external and endoscopic frontal sinus surgery in children.

Background

Both open and functional endoscopic sinus surgery (FESS) are performed in the case of pediatric frontal rhinosinusitis. However, data from comparative analysis of these surgery types are insufficient.

Objective

Prospective randomized trial for comparison of open and endoscopic surgery outcome in pediatric chronic rhinosinusitis.Material and methods: The cohort included 30 pediatric patients (7-17 years) with open frontal sinus surgery and 34 patients who underwent FESS using DrafIIa. Lund-Kennedy and Lund-Mackay scores, as well as Sino-Nasal Outcome Test-20 (SNOT-20)questionnaire was used for pre- and postoperative assessment.

Results

Open surgery and FESS resulted in a significant improvement in total Lund-Kennedy, Lund-Mackay, and SNOT-20 scores, being more profound in FESS group. Using FESS significantly reduced surgery duration by 15% as compared to open surgery. In addition, open surgery was associated with a higher rate of scar formation, reduced local sensitivity, as well as local soreness, lacrimation, and psychological discomfort. In regression models FESS was negatively associated with postoperative total Lund-Kennedy, Lund-Mackay, and SNOT-20 scores.Conclusion and significance: Generally, FESS resulted in better surgery outcome as compared to open surgery, although both approaches resulted in a significant improvement in chronic rhinosinusitis.
