    AIM: To evaluate by histological and immunohistochemical methods the epithelial lesions in vocal nodule and correlate with polyp, laryngeal edema and vocal folds without macroscopic lesions. STUDY DESIGN: Chart review. MATERIAL AND METHOD: In a retrospective analysis of medical records, twenty-six patients, who underwent microsurgical excision of laryngeal inflammatory lesions (nodules, polyps and laryngeal edema), were identified. Vocal folds without macroscopic lesions were obtained from autopsy. To evaluate epithelial lesions, specimens were stained with H&E, PAS, and with antibodies against laminin and collagen type IV. These specimens were analyzed by light microscopy. RESULTS: Lesions diagnosed as nodules showed more collagen type IV and laminin deposition when compared to polyps (p=0,034 and p=0,036, respectively) and to vocal folds without macroscopic lesions (p=0,019 and p=0,021, respectively). Nodules showed basement membranes thicker than polyps on PAS stain (p=0,102). Laryngeal edema could not be differentiated from nodules, polyps or vocal folds without macroscopic lesions by PAS, laminin or collagen type IV stain (p>0,10). CONCLUSION: By histological and immunohistochemical techniques to evaluate epithelium of laryngeal inflammatory lesions we conclude that vocal fold nodule differentiate from polyps on the three techniques used to stain basement membrane (PAS, laminin, collagen IV) and from vocal folds without macroscopic lesions on two techniques used (laminin, collagen IV). Laryngeal edema cannot be differentiated from the others laryngeal lesions, neither from vocal folds without macroscopic lesions, when the techniques before described are used.

    Dystonias are organic central motor processing disorders characterized by involuntary muscular contractions or incontrollable spasms induced by task-specific movements. Adduction laryngeal dystonias present with important speech impairments, with inappropriate spasms and abrupt voice breaks. The diagnosis is based on clinical features, evaluation by a speech therapist and transnasal fiber optic laryngoscopy. AIM: Our objective is to propose and evaluate a task-oriented transnasal fiber optic laryngoscopy protocol, which shows the spasms, and propose maneuvers that reduce or make them disappear, in order to facilitate the diagnosis. METHODS: transversal study. Analysis of the transnasal fiber optic laryngoscopy records of 15 patients with adductor laryngeal dystonia using the proposed protocol. RESULTS: most of the speech and non-vocal tasks allowed us to identify the spasms and reduce or make them disappear. We propose the exclusion of two of the maneuvers that don t bring new data to the evaluation. CONCLUSION: the protocol was useful for the evaluation of the patients, showing changes in muscle behavior in the structure under investigation.

    Paralisia do músculo cricoaritenóideo lateral: relato de caso como contribuição ao estudo da anatomia funcional da laringe

    In the last few years electromyography of the larynx (EMG) has become helpful in the evaluation of vocal fold immobility, especially to differentiate paralysis from fixation, and providing data for diagnosis, site of lesion and prognosis. Based on a case of selective paralysis of lateral cricoarytenoid muscle in a woman who had paralyzed vocal fold at lateral position, confirmed by electromyography study, we conducted an analysis in order to understand the role of intrinsic laryngeal muscles.
