Treatment of Recalcitrant Maxillary Sinusitis With Endoscopic Modified Medial Maxillectomy: A Systematic Review of Safety and Efficacy

Posted on 2019-09-21 - 12:08
Background

Endoscopic sinus surgery is an effective treatment option for patients with chronic rhinosinusitis (CRS), although approximately 20% of patients fail to improve with standard surgical procedures. Expanded procedures such as the endoscopic modified medial maxillectomy (EMMM) have been described in management of refractory maxillary sinusitis.

Objective

This study aims to review the current literature on the safety and efficacy of the EMMM for treatment of refractory maxillary sinusitis.

Methods

A literature search was performed of PubMed, Ovid, and Cochrane databases according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. English-language articles evaluating the EMMM procedure on patients with recalcitrant maxillary sinusitis were included. Full-text articles were obtained and evaluated by 2 reviewers independently, with a third reviewer for mediation of disagreements.

Results

Six studies met eligibility criteria and were included into the study, with follow-up ranging from 12 to 82.8 months. Two studies contained Level 2 evidence and 4 studies contained Level 4 evidence. EMMM was found to be effective in CRS and cystic fibrosis-related CRS (0% and 9.1% revision rate, respectively). Symptom resolution was noted 60% to 80% of patients. Four studies reported complications, with a total of 4 complications out of 211 patients.

Conclusions

There are no high-quality Level 1 studies evaluating the efficacy and safety of the EMMM procedure. Level 2 to Level 4 studies indicate that this procedure is relatively safe with a low complication rate and symptom resolution in up to 80% of patients with recalcitrant maxillary sinusitis.
