Endoscopic-modified medial maxillectomy (EMMM) effectively treats chronic maxillary sinusitis, resolving symptoms and improving sinus function in over 90% of patients. This surgical approach offers a robust solution for non-functioning maxillary sinuses.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Rhinosinusitis Research

Background:

  • Middle meatal antrostomy (MMA) is a traditional treatment for chronic maxillary sinusitis but often fails to restore mucociliary clearance in non-functioning maxillary sinuses.
  • Endoscopic-modified medial maxillectomy (EMMM) offers an alternative by reshaping the sinus, preventing bacterial colonization, and promoting drainage.

Purpose of the Study:

  • To describe a modified EMMM surgical technique for recalcitrant maxillary sinusitis.
  • To evaluate perioperative outcomes, including symptom resolution and mucostasis, in patients undergoing EMMM.

Main Methods:

  • A consecutive series of adult patients with non-functioning maxillary sinuses treated with EMMM were assessed.
  • Primary outcomes included symptom resolution and absence of mucostasis; secondary outcomes were early and late morbidities.

Main Results:

  • Fifty-seven patients were assessed, with 91.2% achieving symptom resolution and 91.2% showing an absence of mucostasis.
  • Early morbidities were low, including temporary dysesthesia, bleeding, and pain, with no late morbidities reported.

Conclusions:

  • EMMM is a robust surgical approach for salvaging non-functioning maxillary sinuses.
  • The procedure effectively enhances nasal irrigation, compensates for lost mucociliary clearance, and prevents mucus retention.
