Lingual frenulum: quantitative evaluation proposal.

UNLABELLED: The purpose of this study was to establish a quantitative method to classify lingual frenulum as normal and altered. METHODS: 98 people were included in this study. All measurements were made with maxium opening of the mouth. A digital caliper was used to measure the length of the frenulum under three conditions: a) with the tongue tip on the incisal papilla; b) with the tongue sucked up and maintained against the hard palate; and c) with tongue stretching over a spatula. RESULTS: Observations indicated that the most useful and statistically significant way of measuring frenulum length was achieved with maximum mouth opening and the tongue tip on the incisal papilla. CONCLUSION: This quantitative method was demonstrated to be effective for identifying and distinguishing normal and altered frenular length.

Lingual frenulum: classification and speech interference.

PURPOSE: To propose a classification of the different lingual frenulum and to relate them to speech disorders. METHODS: We evaluated 1402 patients' frenulum with an age range of 5 years 8 months to 62 years 10 months between 1978 and 2002. Pictures were taken of the altered frenulum. Measures of maximal mouth opening, with and without tongue suction, were taken with a sliding caliper. Speech samples were also taken. Frenulum were then classified as normal; short; with anterior insertion, and short with anterior insertion. RESULTS: From the 1402 patients evaluated, 127 (9%) presented with an altered frenulum insertion. For this study we considered only those with short or with anterior insertion. For those who had an altered frenulum, 62 (48.81%) presented with speech disorders. The more frequent speech disorders were: omission and substitution of /r/; {R}, and consonant clusters with /r/, and of /s/ and /z/. Frontal and lateral lisps also occurred. The frenulum of 21 patients was classified as short and of these, 12 patients (57%) presented with speech disorders. Of the 106 patients with anterior insertion, 50 (47.2%) presented with a speech disorder. After statistical analyses the relation between altered frenulum and speech disorders was considered significant with p<0.001. CONCLUSION: The lingual frenulum was classified as normal, short and with anterior insertion. An altered frenulum may predispose the individual to exhibit an accompanying speech disorder.

[Clinical, endoscopical and manometric evaluation of swallowing in patients with acquired autoimmune myasthenia gravis].

Dysphagia, or difficulty swallowing, is a common problem following myasthenia gravis (MG) and may lead to aspiration of saliva, food or liquids. We herein present 22 MG patients, with complaint of dysphagia, evaluated by phonoaudiological evaluation, nasofibrolaryngoscopical analysis and manometry of upper esophageal sphincter. The main objective was to evaluate the phases of the swallowing process and anatomical and functional aspects of oropharyngeal musculature. The age of patients varied from 19 to 74 years; being 19 female and 3 male. The main data were: (1) statistically significant relation between the phonoaudiological clinical evaluation and nasofibrolaryngoscopical one; (2) stomatognatical system disorders present in 100%; (3) swallowing and chewing disorders present in 100%, when clinically evaluated, and in 81,8% when evaluated by the nasofibrolaryngoscopy; (4) statistically significant relation between penetration/aspiration and antecedents of pneumonia; (5) stomatognatical muscles very altered, difficulty controlling the bolus, collection of food in the pharynx or larynx and presence of penetration and/or aspiration showed significant correlation with weakness of a pharyngeal muscles. These findings justify the necessity to evaluate clinically the swallowing phases in MG patients, with the main purpose to prevent both aspiration and dehidration from inadequate oral intake.
