| Abstract: |
Objectives: We describe the clinical features of granuloma of the membranous vocal fold (as opposed to granuloma of the vocal processor "contact granuloma"), a poorly recognized sequela of microlaryngoscopic surgery. Membranous vocal fold granuloma may mimic the initial lesion in appearance, and thus be mistaken for recurrence. Methods: We performed a retrospective review of cases from 2 institutions. Results: Fifteen cases of membranous vocal fold granuloma from 2 institutions were identified. In all but 1 case, granuloma developed in the early postoperative period, within 8 weeks. Of the 15 cases, 10 followed laser resection of carcinoma. Five were noted following cold steel resection of benign lesions (2 papillomas, 2 cysts, 1 Reinke's edema). Technical aspects of these cases suggest that membranous vocal fold granulomas result from surgical violation of deep tissue planes and/or epithelial defects. All patients were treated with proton pump inhibitors. In 12 cases, the granulomas proved self-limited, resolving over weeks to months following surgery. Three patients underwent surgical removal of the lesion, which confirmed the diagnosis. One of these cases recurred and was treated nonsurgically. Conclusions: Granuloma should be suspected when a mass lesion appears at the surgical site early in the postoperative course. Surgical excision is generally not necessary and may provoke further growth of granulation tissue. © 2007 Annals Publishing Company. All rights reserved. |
