Background and Objectives: Despite aggressive medical therapy and previous endoscopic sinus surgery, there are a subset of patients suffering from recalcitrant, persistent chronic isolated maxillary sinusitis which results from impaired mucocilliary clearance caused by long-standing inflammation. The corresponding patients underwent our newly devised Modified Inferior Meatal Mega-Antrostomy (Modified IMMA). The objective of this study was to review the clinical efficacy and complication after Modified IMMA in patients who had suffered from intractable maxillary sinusitis after endoscopic sinus surgery.
Subjects and Method: Fourteen patients suffering from recalcitrant chronic isolated maxillary sinusitis underwent Modified IMMA between May 2010 and April 2013. The mean follow-up period was an average of about 13 months and regular intervals of postoperative 3-, 6-, 9-, 12-months were set. A retrospective review was performed to analyze the preoperative & postoperative Visual Analogue Scale score (VAS score) and Lund-Kennedy endoscopy score at each interval. VAS scores and endoscopic findings were processed statistically at the time of third postoperative month. The exclusion criteria were an obstructed ostiums, osteitis, systemic disease such as Ig A/G immunodeficiency, primary ciliary dyskinesia.
Results: The postoperative VAS scores and Lund-Kennedy scores, when compared with those prior to Modified IMMA, decreased from 16.5 to 2.5 and 5.0 to 1.0, respectively. Also, there was no serious complication or recurrence associated with the procedures.
Conclusion: Our newly devised Modified IMMA could be a much effective option for surgical treatments in patients with recalcitrant chronic isolated maxillary sinusitis.
