Background

Middle meatal antrostomy (MMA) is the traditional intervention for chronic maxillary sinusitis but often fails to correct a nonfunctioning maxillary sinus that has lost its capability for mucociliary clearance. Endoscopic-modified medial maxillectomy (EMMM) can reshape the maxillary sinus and avoid a “sumping” effect, preventing secondary bacterial colonization, encouraging dependent drainage, and promoting effective nasal irrigation.

Objectives

We describe a modification of the EMMM surgical technique in patients with recalcitrant maxillary sinusitis and perioperative outcomes.

Methods

Consecutive adult patients with nonfunctioning maxillary sinuses managed with EMMM were assessed. Primary outcomes were the resolution of the presenting symptom and the absence of mucostasis. Secondary outcomes were early (<90 days) and late (>90 days) morbidity.

Results

Fifty-seven patients (51.7 ± 17.5 years, 56.1% female) were assessed. Fifty-two patients had complete resolution of their presenting symptom (91.2% [95% CI: 80.7–97.1]) and 52 patients had an absence of mucostasis (91.2% [95% CI: 80.7–97.1]). Those with persistent crusting were also those with symptoms. Early morbidities included temporary dysesthesia (3.2%), bleeding (1.1%), and pain (3.2%), with no late morbidities.

Conclusion

EMMM is a robust approach for salvaging a nonfunctioning maxillary sinus. The procedure enhances nasal irrigation, supplants mucociliary clearance, and discourages dependent mucus retention.
