1. Diffusion of aniline blue injected into the thyroarytenoid muscle as a proxy for botulinum toxin injection: an experimental study in cadaver larynges
INTRODUCTION: Endolaryngeal injection of botulinum toxin into the thyroarytenoid (TA) muscle is one of the methods for treatment of focal laryngeal dystonia. However, after treatment, there is variation in laryngeal configuration as well as the side effects reported by patients. As a consequence of the functional variability of results, it was hypothesized t

2. Use of surface electromyography in phonation studies: an integrative review
INTRODUCTION: Surface electromyography has been used to assess the extrinsic laryngeal muscles during chewing and swallowing, but there have been few studies assessing these muscles during phonation. OBJECTIVE: To investigate the current state of knowledge regarding the use of surface electromyography for evaluation of the electrical activity of the extrinsi

3. Adult Rhabdomyoma of the Larynx
Introduction Rhabdomyoma is a rare benign tumor derived from skeletal muscles. Laryngeal rhabdomyomas are even rarer, with only approximately 40 reported cases in world literature. Laryngeal rhabdomyomas usually are seen as masses covered by mucosa. They are often solitary asymptomatic tumors, but symptoms such as hoarseness can occur. The radiologic fea

4. Protection from myonecrosis, and expression of SERCA1 and calsequestrin in dystrophic laryngeal muscles / Musculos laringeos distroficos : proteção a mionecrose, expressao de SERCA1 e calsequestrina
Duchenne muscular dystrophy (DMD) and mdx mice, a model for DMD, is characterized by the lack of dystrophin expression and muscle fiber necrosis. Some muscle are enigmatically protected and admitted that an elevated expression of calcium-binding proteins. The intrinsic laryngeal muscles (ILMs) share many anatomical and physiological properties with extra-ocu

5. Eletroneuromiografia da laringe : aspectos tecnicos, estudo normativo e contribuição ao diagnostico e tratamento das alterações da mobilidade das pregas vocais
Laryngeal Electromyography (LEMG) is an auxiliary method used for the comprehension and diagnosis of different neurological diseases that compromise laryngeal function. This thesis was wrote in 4 chapters: 1) Laryngeal electromyography: technical features; 2) Laryngeal electromyography in normal brazilian population; 3) Laryngeal eletromyography contribution

6. Spectral analyses of activity of laryngeal and orofacial muscles in stutterers.
Previous studies have reported that the disfluent speech of stutterers is often associated with tremor in orofacial muscle systems. In the present report, spectral analyses of the amplitude envelopes of laryngeal and orofacial EMGs revealed that tremor-like oscillations of EMG activity, similar to those observed in orofacial muscles, are also present in lary

7. Immunohistochemical Analysis of Laryngeal Muscles in Normal Horses and Horses With Subclinical Recurrent Laryngeal Neuropathy
We used immunohistochemistry to examine myosin heavy-chain (MyHC)-based fiber-type profiles of the right and left cricoarytenoideus dorsalis (CAD) and arytenoideus transversus (TrA) muscles of six horses without laryngoscopic evidence of recurrent laryngeal neuropathy (RLN). Results showed that CAD and TrA muscles have the same slow, 2a, and 2x fibers as equ

11. Loss of large myelinated nerve fibres of the recurrent laryngeal nerve in patients with multiple system atrophy and vocal cord palsy.
OBJECTIVES: Vocal cord palsy seen in some patients with multiple system atrophy may result from neuronopathy of the recurrent laryngeal nerve. METHODS: Six controls and six patients with multiple system atrophy, four with and two without vocal cord palsy were studied. The number of myelinated nerve fibres were counted and fibre diameter histograms were estab

12. From fish to modern humans – comparative anatomy, homologies and evolution of the head and neck musculature
In a recent paper Diogo (2008) reported the results of the first part of an investigation of the comparative anatomy, homologies and evolution of the head and neck muscles of osteichthyans (bony fish + tetrapods). That report mainly focused on actinopterygian fish, but also compared these fish with certain non-mammalian sarcopterygians. The present paper foc
