OBJECTIVES Voice disorders affect adults and children and have different causes in different age groups. The aim of the study is to present the etiology and diagnosis dysphonia in a large population of patients with this voice disorder.for dysphonia of a large population of dysphonic patients. METHODS We evaluated 2019 patients with dysphonia who attended(More)
UNLABELLED Nasal septum deviation (SD) and turbinate hypertrophy (TH) increase the resistance to respiratory airflow and may impair nasal patency. OBJECTIVE To characterize the nasal geometry of individuals with nasal obstruction secondary to SD and/or TH by means of acoustic rhinometry. METHOD This prospective study included 30 adults with complaints(More)
To evaluate the participation of the larynx and cervical trachea in conditioning inspired gases, we randomly allocated 16 mixed-breed dogs to two groups: group TT (tracheal tube; n = 8) and group LMA (laryngeal mask airway; n = 8). The dogs were anesthetized with pentobarbital sodium and mechanically ventilated for 3 hours. The parameters studied were(More)
UNLABELLED Hearing loss in hypothyroidism has been reported by many authors but its pathophysiology is unclear. AIMS to study the audiological evaluation of patients with acquired hypothyroidism. MATERIALS AND METHODS two groups were included: a hypothyroidism group (HG, n-30), and a control group (CG, n-30). Parameters studied: gender, time of(More)
UNLABELLED Congenital and acquired airway diseases are responsible for upper respiratory distress and stridor in children. In neonatal intensive care units, we have seen increased survival in premature babies, but also a high incidence of airway complications related to intubation, which present as stridor. AIM To review endoscopic findings in children(More)
The effects of anesthetics on cytokine release in patients without comorbidities who undergo minor surgery are not well defined. We compared inflammatory cytokine profiles in adult patients undergoing minimally invasive surgery who received isoflurane or propofol anesthesia. Thirty-four patients without comorbidities undergoing minor surgery were randomly(More)
UNLABELLED Granulomas are bilateral and pediculated lesions of the vocal apophysis. Etiologies: intubation, reflux, trauma, vocal abuse, idiopathic origin. AIM To analyze the clinical and morphological aspects of post intubation granulomas. METHODS retrospective study of patients submitted to microsurgery for post intubation laryngeal granulomas seen at(More)
UNLABELLED Laryngeal papillomatosis is the most frequent benign neoplasia in children. It is caused by HPV 6 and 11. The lesions are exophytic and highly recurrent, compromising the airway mucosa, mainly the larynx. Study design--clinical prospective. AIMS To show morphologic alterations of the epithelium (light and electron microscopy) in the HPV-6(More)
OBJECTIVE To examine, by using scanning electron microscopy, the surface of the tongue, pharynx, and larynx of animals exposed to tobacco. STUDY DESIGN Experimental study. METHODS Twenty rats were allocated to two groups: group I, control group: 10 rats not exposed to any inhaling pollutant and group II, tobacco group: 10 rats exposed to smoke from 10(More)
