Outcomes of middle meatal antrostomy after different surgical strategies.

CONCLUSION

There was no significant difference in the postoperative outcomes between different surgical options for treating chronic maxillary sinusitis (CMS).

OBJECTIVE

We aimed to compare the improvement in symptoms, and changes in endoscopic and CT grade in patients undergoing different surgical management of the maxillary sinus ostium.

METHODS

In 32 patients (group A), the pathologic mucosa was radically removed with a power microdebrider. In 28 patients (group B), only part of the pathologic mucosa was removed; gross pathologic lesions were left in situ. In 38 patients (group C), only enlargement of the maxillary ostium was performed. Pre- and postoperative changes in symptoms, endoscopic polyp grade, and Lund-Mackay CT score were compared between groups.

RESULTS

In all groups, the symptoms were significantly improved after 1 month and throughout the follow-up period. Patients in groups A and B had meaningful improvement of the endoscopic polyp grade 1 month after surgery. The endoscopic grade of patients in group C at 1 and 3 months after surgery was not significantly different from the preoperative grade; however, there was a meaningful difference after 6 months. At 12 months after surgery, all groups had a significant decrease in the CT score (p < 0.01); however, there was no difference between groups.
