Nonarytenoid laryngeal granulomas.
The patient subsequently underwent microdirect laryngoscopy, excision of a left true vocal fold granuloma, angiolytic KTP laser treatment of the attachment site, and dexamethasone injection. Two weeks postoperatively, she was doing well with no evidence of recurrent granuloma (figure 2).
Contact granulomas are benign lesions of the larynx that characteristically develop posteriorly at the vocal process of the arytenoid. The most common presenting symptom is hoarseness, with sore throat, dyspnea on exertion, globus, stridor, and "cut-off voice" occurring less commonly. (1)
Contact granulomas result from trauma, often due to laryngopharyngeal reflux, chronic cough, and throat clearing, as well as vocal abuse. They are perpetuated by repeated contact between vocal processes during phonation. (2) This prevents adequate wound healing and leads to ulcer formation with subsequent reactive tissue overgrowth, often presenting as a nodular, reddish lesion. (3) These granulomas, however, lack typical features of granulomatous lesions on light microscopy. Instead, histopathology of contact granulomas includes hyperplastic epithelium, granulation tissue, and chronic inflammatory infiltrate, with no reported cases of malignant transformation. (4,5)
Very rarely, contact and postintubation granulomas are located on the middle third or anterior portion of the vocal folds, with few reported in the literature. The senior author (R.T.S.) has described a case ofbilateral granuloma and varicosity in the midportion of the vocal folds, as well as a laryngeal granuloma of the false vocal fold. (6,7) The natural course and treatment of contact versus postintubation granulomas differ, as contact granulomas have a high likelihood of recurrence (92%) when removed surgically. (8) The mainstay of treatment of contact granulomas is conservative, consisting initially of anti-reflux medication and voice therapy. Surgical removal is reserved primarily for cases refractory to medical treatment or when the diagnosis is in doubt, and "bloodless" in-office techniques such as KTP laser treatment can offer increased accessibility, decreased morbidity, and lower recurrence rates than traditional cold steel microlaryngoscopy techniques, but at the expense of complete histologic evaluation.
