Introduction Studies have reported that although speech perception in noise was unaltered with and without digital noise reduction (DNR), the annoyance toward noise measured by acceptable noise level (ANL) was significantly improved by DNR with the range between 2.5 and 4.5 dB. It is unclear whether a similar improvement would be observed in those individuals who have an ANL ≥ 14...

IntroductionChronic rhinosinusitis (CRS) is a highly prevalent pathology in our society. Due to the prevalence of this condition and to the persisting symptoms despite an appropriate medical treatment, surgical techniques are often required. Lately, minimal invasive techniques have been described, such as lacrimal diversion devices (LDDs). This technique offers a fast and...
Introduction Upper airway obstruction at multiple sites, including the velum, the oropharynx, the tongue base, the lingual tonsils, or the supraglottis, has been resulting in residual obstructive sleep apnea (OSA) after tonsillectomy and adenoidectomy (TA). The role of combined lingual tonsillectomy and tongue base volume reduction for treatment of OSA has not been studied in...
Introduction Acute acoustic trauma, which is a kind of sensorineural hearing loss, is caused by acoustic overstimulation. Hyperbaric oxygen therapy (HBOT) is reported to be effective against acute acoustic trauma.Objective We aimed to evaluate the efficacy of HBOT against acoustic hearing loss based on our 20 years of experience with such cases.Methods Patients who were treated...
Introduction Tonsillectomy is one of the most common otolaryngology procedures performed worldwide. It is also one of the first procedures learnt by residents during their training period. Although tonsillectomy is viewedrelatively as a low-risk procedure, it can be potentially harmful because of the chance of posttonsillectomy hemorrhage.Objective The objective of the present...
Introduction Frequency-following response with speech stimulus (FFR-speech) is a subcortical potential that satisfactorily evaluates the processing of verbal information. However, there still are differences in the literature regarding its analysis and stimulation protocol.Objective To compare two stimulation protocols for the capture of FFR-speech, to identify the percentage of...
Introduction Agrochemicals, also known as pesticides, are widely used in agriculture and in public health. They are organic and inorganic chemical substances with a high level of toxicity not only for the environment, but also for human health.Objective To verify findings on labyrinthine assessment in endemic disease control agents, and to recommend the inclusion of the...
Introduction The understanding of normal vocal production is essential to guide any voice professional as it is fundamental to understand the effects of the posterior glottal gap on the vocal quality.Objective The aim of the present study was to verify the association between glottic closure, acoustic parameters, and some characteristics of the videolaryngostroboscopy of young...
Introduction The Speech, Spatial and Qualities of Hearing Scale (SSQ) is a questionnaire designed to assess the auditory experience and quantify hearing disabilities in realistic communication situations, with particular attention to binaural hearing.Objective To determine the test-retest reliability of the SSQ in Brazilian Portuguese.Method A total of 35 individuals with mean...
Introduction Physical inactivity is an important risk factor for many aging-related symptoms. Studies suggest that physical activitymay help to relieve tinnitus and headache.Objective To investigate the presence of tinnitus and headache in elderly individuals by associating it with the lack of regular physical activity.Methods A cross-sectional study including elderly individuals...

Introduction Schwannomas are benign tumors originating from differentiated Schwann cells. Being the least common intraoral neoplasm of neural origin, it is rarely seen in the palate. The literature lacks an extensive review of intraoral schwannoma confined to the palate.Objective To review previously reported cases of palatal schwannoma along with an illustrative case, and to...
Introduction Schwannomas are benign, solitary, encapsulated tumors that may originate at any site of the peripheral nervous system, with the exception of the olfactory and optic nerves. Schwannomas of the base of tongue are very rare, and only sporadic cases are documented. The tongue base represents a challenge for surgeons. Carbon dioxide (CO2) laser might provide an effective...
Introduction Dysphagia, when left untreated, can result in an increase in morbidity and mortality rates, especially among infants with history of life-threatening neonatal diseases. The videofluoroscopy swallowing study (VFSS) is considered the gold standard for the diagnosis of dysphagia. There are few imaging studies of infant swallowing based on videofluoroscopy, none of which...
Introduction The main modalities of surgical treatment for laryngeal cancer include transoral laser microsurgery (TLM), open preservation surgery, and total laryngectomy (TL). In the elderly, for the presence of comorbidities, the surgical approach more appropriate in many cases remains TL. The use of a stapler for the closure of the esophagus has been introduced to reduce...
Introduction Sulcus vocalis is defined as a longitudinal depression on the vocal cord, parallel to its free border. Its most marked characteristic is breathlessness, caused by incomplete glottal closure, in addition to roughness, due to the decrease in mucosal wave amplitude of the vocal cords. Vocal acoustic aspects, such as fundamental voice frequency, jitter, and shimmer, may...
Introduction Oral antihistamines and intranasal corticosteroids have been shown to be effective and safe for the treatment of allergic rhinitis; however, the evidence suggests a level of superiority of corticosteroids, so they should be preferred over the former.Objective To know the prescription profile of two second generation antihistamines (cetirizine and levocetirizine) and...
Introduction Laryngeal granulomas are benign, recurrent lesions of many causes (reflux, voice abuse, intubation, and idiopathic), which renders its treatment difficult.Objective To describe our experience in the treatment of laryngeal granulomas.Methods From 16 medical records of the patients with laryngeal granulomas seen between 2010 and 2017 in a university hospital, the...
