Análise comparativa do equilíbrio postural de indivíduos com e sem histórico de labirintite: estudo preliminar / Comparative analysis of postural balance between individuals with and without labyrinthitis: preliminary study

O objetivo deste estudo foi comparar o equilíbrio postural entre indivíduos com e sem histórico de labirintite por meio de um estudo transversal controlado, cuja amostra foi composta por um grupo de 12 participantes jovens, sem labirintite, do sexo feminino com média de idade de 22 ± 2,23 anos e índice de massa corporal 21,12 ± 2,09 e outro grupo composto por 12 indivíduos do sexo feminino com histórico de labirintite, porém fora de crise e com média de idade de 22 ± 1,46 anos e índice de massa corporal de 23,42 ± 3,52. O registro do deslocamento do centro de pressão foi realizado por uma plataforma de pressão F-Mat modelo 3100 do sistema F-Scan com software versão 4.2 (Tekscan, Inc., South Boston, MA), sendo avaliado o comprimento total da trajetória (CT), o deslocamento ântero-posterior (AP), médio-lateral (ML) e a velocidade máxima (VM). O teste t para amostras independentes encontrou diferenças estatisticamente significativas no parâmetro comprimento total da trajetória (CT) entre as medidas dos grupos, demonstrando que os indivíduos com histórico de labirintite estudados, mesmo fora da crise, mostraram equilibro postural deficitário quando comparado aos indivíduos do grupo sem histórico de labirintite.

The purpose of this study was to compare postural balance between individuals with and without history of labyrinthitis through a cross-controlled study, whose sample was composed by a group of 12 young participants females, without labyrinthitis, 22 ± 2.23 years old and body mass index of 21.12 ± 2.09, and another group composed of 12 individuals female with history of labyrinthitis beyond crisis, 22 ± 1.46 years old and body mass index 23.42 ± 3.52. The record of the displacement of the center of pressure was conducted by a platform of pressure F-Mat model 3100 of the F-Scan system with software version 4.2 (Tekscan, Inc., South Boston, MA), being measured total length path, anterior-posterior and medial-lateral displacement and maximum speed. The t-test for independent samples found significant differences statistical in the parameter total length path between the actions of groups demonstrating that individuals with a history of labyrinthitis studied showed postural balance deficit when compared to individuals in the group without history of labyrinthitis.

A Case of Tympanogenic Labyrinthitis Complicated by Acute Otitis Media

Widespread use of antimicrobial drugs in the management of otitis media has significantly reduced the incidence of labyrinthitis nowadays. Cases of tympanogenic labyrinthitis following acute otitis media have rarely been reported in recent literature on otolaryngology. We report an unusual case of tympanogenic labyrinthitis that presented with sudden sensorineural hearing loss (SNHL) following acute otitis media in an adult who had no previous otological complaints. An audiogram revealed SNHL with pure tone threshold of 43.7 dB in the left ear. MRI was helpful to identify the inflammatory change of the membranous labyrinth. The patient's hearing returned to normal after treatment. The definite diagnosis of serous labyrinthitis was established retrospectively.
