[Association between interleukin-6 polymorphism in the -174 G/C region and hearing loss in the elderly with a history of occupational noise ...
The biological processes involved in noise-induced hearing loss (NIHL) are still unclear. The involvement of inflammation in this condition has been suggested. To investigate the association between interleukin - 6 (IL-6) polymorphism and susceptibility to NIHL. This was a cross-sectional study with...
Overview of newborn hearing screening programs in Brazilian maternity hospitals.
Newborn hearing screening has as its main objective the early identification of hearing loss in newborns and infants. In order to guarantee good results, quality indicators for newborn hearing screening programs are used as benchmarks. To observe and describe the reality of national newborn hearing...
Otoneurological evaluation: current good practice.
Endoscopic endonasal technique: treatment of paranasal and anterior skull base malignancies.
Technical and technological innovations have spearheaded the expansion of the indications for the use of endoscopic endonasal approaches to extirpate malignancies of the sinonasal tract and adjacent skull base. Critical review of the available literature regarding the use of endoscopic endonasal app...
Facial nerve grafting and end-to-end anastomosis in the middle ear: tympanic cavity and mastoid.
Sectioned facial nerves can be repaired with grafting or end-to-end anastomosis. To discuss these repair procedures and what can be expected of them. Seven patients with sectioned facial nerves were included in the study. Four underwent grafting and three were offered end-to-end anastomosis. Facial...
Cochlear implantation through the middle cranial fossa: a novel approach to access the basal turn of the cochlea.
The classic approach for cochlear implant surgery includes mastoidectomy and posterior tympanotomy. The middle cranial fossa approach is a proven alternative, but it has been used only sporadically and inconsistently in cochlear implantation. To describe a new approach to expose the basal turn of th...
Evolution of endoscopic surgery in the treatment of inverted papilloma.
We assessed patients age, gender, tumor side, symptoms, diagnosis, comorbidities and habits, Krouse staging, surgical approach, intraoperative and postoperative, and malignant postoperative recurrence and also the correlation between recurrence with preoperative staging, the surgical approach used,...
Rosai-Dorfman disease as a differential diagnosis of nasosinusal polyposis in children.
Influence of aging on hyaluronic acid concentration in the vocal folds of female rats.
We used the vocal cords of 13 female rats divided into two groups: five aged rats and eight young ones. The tissue concentration of hyaluronic acid was determined using the fluorimetric method with the hyaluronic acid binding-protein coated on plates of enzyme-linked immunosorbent assay (ELISA), con...
Result on speech perception after conversion from Spectra® to Freedom®.
New technology in the Freedom® speech processor for cochlear implants was developed to improve how incoming acoustic sound is processed; this applies not only for new users, but also for previous generations of cochlear implants. To identify the contribution of this technology-- the Nucleus 22®--on...
