We analyzed the functional outcome and self-evaluation of the voice of patients with T1 glottic carcinoma treated with endoscopic laser surgery and radiotherapy. We performed an objective voice evaluation, as well as a physical, emotional and functional well being assessment of 19 patients treated with laser surgery and 18 patients treated with(More)
Two groups of four rabbits each were used. In the first group, the greater auricular nerve was grafted into the ipsilateral facial nerve. In the second group, the facial nerve was grafted into the contralateral facial nerve. Electromyographic studies were performed on both groups 21 to 24 weeks afterward, together with an axonal count of the grafted nerves(More)
Invasive head and neck squamous carcinomas are among the cytogenetically most complex tumors. Perhaps for this reason, there is little consensus on the prognostic value of specific chromosomal aberrations. Here we present results of CGH analysis of 56 clinically well-characterized set of head and neck cancers, consisting of larynx and pharynx only. The aim(More)
OBJECTIVES To determine the sensitivity and specificity of the head-shaking nystagmus test (HSN), the nystagmus elicited in response to a vigorous rotation of the head in the horizontal plane, in the study of patients with peripheral unilateral vestibular disease. PATIENTS AND METHODS Retrospectively, we analyze the relationships between the HSN and the(More)
The purpose of this study was to explore the interaction between voice asthenicity and the acoustic prediction of vocal hypofunction. One hundred and seven phonatory samples of Reinke's edema were categorized by listeners using GRBAS scale. Seven frequency and time domain parameters were used to predict perceptual severity of asthenicity. Logistic regresion(More)
The perceptual GRBAS scale for analysis of voice quality is quite important clinically in voices that cannot be effectively analyzed with a voicing parameter method like vocalizations with strong subharmonics and modulations and in chaotic or random voices. In the present study, two experiments were performed: Firstly, GRBAS/acoustical correlations were(More)
Subjective voice qualities are difficult to transform into permanent objective visual patterns. Voice spectrography is not a new method of voice analysis. However, in spite of many contributions to the literature, few otolaryngologists have used this interesting method as a clinical tool for evaluating the voice before and after surgical voice procedures.(More)
The limits of the vestibular nuclei and accessory groups were analyzed in 7 rats. This information was taken using camera lucida drawings of the vestibular nuclei and their neurons in serial sections. The study of the morphometric parameters of the neurons (area and maximum diameter) were accomplished by means of a program for image analysis. The cells of(More)
A quantitative study was made of the number of fibers, their diameters and patterns of distribution in 14 ampullar nerves of chinchilla. The nerves were processed for osmium staining, embedded in plastic and cut serially in 1-micron-thick sections for histologic evaluation. Quantitative evaluation of nerve-fiber characteristics was made with the aid of a(More)
The classical concept of the autonomic innervation of the nasal mucosa states that the postganglionic sympathetic neurones lie in the superior cervical ganglion and those of the postganglionic parasympathetic neurones are in the pterygopalatine ganglion. We have carried out a study of the fine structure of the respiratory nasal mucosa in man and in the cat(More)
