Effectiveness of the Endoscopic Prelacrimal Recess Approach for Maxillary Sinus Inverted Papilloma Removal: A Systematic Review and Meta-Analysis

Background Conventional minimally invasive surgery has a high recurrence rate, and nasal morbidity can occur if the scope of surgery is expanded to complete removal of maxillary sinus inverted papilloma.Objective To analyze the efficacy of the endoscopic prelacrimal recess approach (EPLRA) for maxillary sinus inverted papilloma removal.Methods Eighteen studies were included in this meta-analysis. Articles comparing the prelacrimal recess approach with conventional surgery (endoscopic surgery or the Caldwell–Luc operation) for inverted papilloma removal were included. Outcomes of interest included recurrence and postoperative morbidities. The methodological quality was assessed using the Newcastle–Ottawa scale.Results The recurrence rates of inverted papilloma, postoperative facial or gingival numbness, and alar collapse were 3.13% (95% confidence interval [CI]: 1.32, 7.27), 9.02% (95% CI: 3.70, 20.39), and 3.39% (95% CI: 1.28, 8.68), respectively. The recurrence rate of inverted papilloma was significantly lower after the EPLRA than after conventional surgery (odds ratio [OR] = 0.2290; 95% CI: 0.0808, 0.6489). However, there were no significant differences between the procedures in the rates of facial or gingival numbness (OR = 0.4567; 95% CI: 0.1497, 1.3933), epistaxis (OR = 0.3150; 95% CI: 0.0471, 2.1044), or periorbital swelling (OR = 1.2405; 95% CI: 0.1205, 12.7731).Conclusions The EPLRA can preserve the lacrimal system and is useful for maxillary sinus inverted papilloma removal due to a lower recurrence rate compared with conventional surgeries.
