Nasal septum deviation (NSD) typically occurs following otorhinolaryngologic surgery. However, there is a lack of biomechanical parameters able to accurately evaluate the severity of NSD. The present study aimed to determine whether the deformation rate (DR) is associated with visual analogue scale (VAS) and nasal airway resistance (NAR), and to evaluate the application of DR measurements in na...

PURPOSE To examine the CT and MR appearances of four packing materials commonly used in otolaryngologic surgery. METHODS The CT and MR appearances of bismuth and iodoform paraffin paste, aqueous betadine gauze, calcium sodium alginate, and triadocortyl cream were examined. CT attenuation values were measured using phantoms containing packing materials. MR characteristics were examined by pack...

Septoplasty is one of the most common otorhinolaryngologic surgical procedure. It is customary to place a pack in the nose as a part of nasal surgery to stop bleeding, enhance apposition of mucosal flaps, and stabilize the operated septal cartilage and bones. But nasal packing is not an innocuous procedure. The most common problem encountered by the patients after septoplasty with nasal pack is...

Mucopolysaccharidoses (MPSs) are lysosomal storage disorders caused by deficiency of enzymes involved in the degradation of glycosaminoglycans (GAGs). These disorders are associated with the accumulation of GAGs in tissues with organomegaly, mental retardation and short stature. Otologic and upper respiratory tract pathologies are among the earliest clinical manifestations. We analyzed 20 patie...

Mucormycosis is a rare fungal infection that can involve the sino-orbito-cerebral region. Sino-orbito-cerebral mucormycosis is most common in patients who are immunocompromised or have diabetes mellitus, severe malnutrition or burns. This condition can be fatal if it is not diagnosed early and treated aggressively. This article presents 4 cases of mucormycosis, including 2 with orbital apex syn...

OBJECTIVE To validate the technique of sleep nasendoscopy using target controlled infusion in symptomatic patients and a control group of asymptomatic individuals. DESIGN Prospective cohort study. SETTING Department of otolaryngology-head and neck surgery and anesthesia in a teaching hospital. PARTICIPANTS Two groups of patients were compared and matched for their body mass index. The fir...

BACKGROUND The aim of this study was to describe the pattern of inheritance and the clinical features in a large family with Waardenburg syndrome type I (WS1), detailing the dental abnormalities and screening for PAX3 mutations. MATERIAL AND METHODS To characterize the pattern of inheritance and clinical features, 29 family members were evaluated by dermatologic, ophthalmologic, otorhinolaryn...

PURPOSE To investigate the process of fatigue in orbicularis oris muscles by analyzing the median frequency of electromyographic signal and the referred fatigue time, according to the breathing mode and the facial pattern. METHODS The participants were 70 children, aged 6 to 12 years, who matched the established criteria. To be classified as 36 nasal-breathing and 34 mouth-breathing children,...

BACKGROUND Leber congenital amaurosis (LCA) is the earliest and most severe inherited retinal degeneration. Isolated forms of LCA frequently result from mutation of the CEP290 gene which is expressed in various ciliated tissues. METHODS Seven LCA patients with CEP290 mutations were investigated to study otorhinolaryngologic phenotype and respiratory cilia. Nasal biopsies and brushing were per...

UNLABELLED Chronic and persistent mouth or oral breathing (OB) has been associated with postural changes. Although posture changes in OB causes decreased respiratory muscle strength, reduced chest expansion and impaired pulmonary ventilation with consequences in the exercise capacity, few studies have verified all these assumptions. OBJECTIVE To evaluate exercise tolerance, respiratory muscle...
