Treatment of mycosis of maxillary sinus by nasal endoscopic surgery / 中国微创外科杂志

ABSTRACT

Objective To explore the curative effect of endoscopic simple maxillary ostium enlargement in the treatment of non-invasive mycosis of maxillary sinus. Methods Clinical data of 16 cases of noninvasive mycosis of maxillary sinus were analyzed retrospectively. Results The operation time was 30～120 minutes, with a mean of 60 minutes. No operative complications occurred. The hospital stay was 5～7 days, with a mean of 6 days. Histopathological examination found hyphae and spores in 16 cases, and a positive culture of Aspergillus was observed in 9 cases. Postoperative follow-up for 3～24 months (mean, 18 months) in 16 cases revealed free of symptoms in 14 cases, in which the endoscopic examination showed unobstructed ostium and normal sinusal mucosa, and recurrence in 2 cases, who underwent repeated enlargement of ostium and were re-followed for 6 and 13 months, respectively, without recurrence. Conclusions Nasal endoscopic simple maxillary ostium enlargement in the treatment of non-invasive mycosis of maxillary sinus is a radical and minimally invasive technique, but particular attention must be directed to managing the maxillary ostium.
