Abstract

Background: The study aims to compare EPMM with conventional CLA to remove benign lesions of the maxillary sinus and to evaluate the usefulness of these approaches.

Patients and Methods: A total of 24 patients of which eight patients diagnosis of antrochoanal polyps recurrent cases, 4 are inverted papilloma, 8 are maxillary Naso alveolar cysts,1 is an oroantral fistula, 2 with maxillary osteoma and 1 with the maxillary fibroma. These cases divided into two groups: group 1 included eight patients who underwent surgery with endoscopic prelacrimalmaxillectomy approach (EPMMA) group 2 underwent surgery by the Caldwell-Luc approach(CLA). They were followed up for six months. Surgical complications and recurrence were evaluated.

Results: The most common symptoms were nasal obstruction (66.6%), rhinorrhea (54%), headache (25%), hyposmia (20.8%). The study found that postoperative complications varied between both groups. Recurrence was seen in the EPMMA group is 66.6% and 0% in the CLA group.

Conclusion: EPMM is a useful approach for benign lesions of the entire wall of the maxillary sinus. The facial numbness after surgery was significantly shorter in EPMMA than that of CLA. The recurrence rate is less in CLA when compared to EPMMA.
