Does a patient with acquired arbovirus infection have a hearing impairment? A scoping review of hearing changes in an adult with Dengue, Chikungunya, and Zika.

Objectives: To identify and understand the evidence regarding hearing changes related to acquired Dengue, Chikungunya, and Zika virus infection in adult individuals.

Methods: A scoping review was performed according to the recommendations of The Joanna Briggs Institute and guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews in the Embase, PubMed/Medline, ScienceDirect, Scopus, and Web of Science databases without restriction on language and year of publication. Case studies, observational studies, and clinical trials reporting hearing loss in adult subjects (>18-60 years of age) of both sexes with DENV, CHIKV, or ZIKV diagnosed by positive molecular/serological examination by RT-PCR or IgM/IgG by ELISA method were included.

Descriptive study of goat external and middle ear through computed tomography and endoscopic evaluation, compared with the human ear.

Objective: To describe the external and middle ear of goats, using computed tomography and endoscopic dissection, comparing them with the anatomy of the human ear, aiming to evaluate the viability of this animal model for training in otological endoscopic surgery.

Methods: Images of the external and middle ear of goats were produced by computed tomography in the coronal and axial planes and analyzed. The radiological anatomy of the external and middle goat and human ear are described.

Use of nasal mucosa graft in tympanoplasty.

Introduction: Tympanoplasty techniques with different types of graft have been used to close tympanic perforations since the 19th century. Tragal cartilage and temporalis fascia are the most frequently used types of graft. They lead to similar functional and morphological results in most cases.

Tentorial Peeling: Surgical Extradural Navigation to Protect the Temporal Lobe in the Focused Combined Transpetrosal Approach.

Background: Transpetrosal approaches have been used for treatment of tumors in the petroclival region for many years. Injury to the temporal lobe, however, has been a potential drawback of the techniques described to date.

Objective: To describe modifications of the transpetrosal surgical technique, which allows extradural manipulation of the temporal lobe during the focused combined transpetrosal approach.

DIABETES REMISSION RATE IN DIFFERENT BMI GRADES FOLLOWING ROUX-EN-Y GASTRIC BYPASS.

Background: Type 2 diabetes mellitus has a high long-term remission rate after laparoscopic Roux-en-Y gastric bypass (LRYGB), but few studies have analyzed patients with BMI<35 kg/m2.

Aim: To compare glycemic control after LRYGB between BMI 30-35 kg/m2 (intervention group or IG) and >35 kg/m2 patients (control group or CG) and to evaluate weight loss, comorbidities and surgical morbidity.

Methods: Sixty-six diabetic patients (30 in IG group and 36 in CG group) were submitted to LRYGB.

Treatment of tympanic membrane perforation using bacterial cellulose: a randomized controlled trial.

Introduction: Promising treatments for tympanic membrane perforation closure have been studied. Therapies derived from tissue engineering probably eliminate the need for conventional surgery. Bacterial cellulose is presented as an alternative that is safe, biocompatible, and has low toxicity.

The anatomical orientation of the middle turn of the cochlea: importance during surgical implantation of the ossified cochlea.

Hypothesis: The physical relationship between anatomical landmarks such as the tympanic portion of the facial nerve and the orientation of the middle turn of the cochlea are sufficiently constant to provide guidance to surgeons performing cochlear implantation in the ossified cochlea.

Background: Placing an implant in an ossified cochlea is technically difficult. The surgeon needs to drill two tunnels through the promontory bone to insert electrode arrays in the region of the basal and middle turns of the cochlea.

Middle ear packing materials: comparison between absorbable hemostatic gelatine sponge and sugarcane biopolymer sponge in rats.

Introduction: Several biomaterials can be used in ear surgery to pack the middle ear or support the graft. The absorbable gelatin sponge is the most widely used, but it may produce fibrosis and impair ventilation of the middle ear.

Objective: This experimental study aimed to investigate the inflammatory effects of the sugarcane biopolymer sponge (BP) in the rat middle ear compared with absorbable gelatin sponge (AGS).

Effect of sugarcane biopolymer gel injected in rabbit vocal fold.

Introduction: Alterations in the vocal folds that involve volume reduction and glottal closure failure result in exaggerated air escape during speech. For such situations, the use of implants or grafts of different materials has been proposed.

Objective: To define the effect of sugarcane biopolymer gel when implanted in the vocal folds of rabbits.

[Sugarcane biopolymer membrane: experimental evaluation in the middle ear].

New developments on biomaterials are important in surgery. The behavior of a new membrane produced from sugarcane will be evaluated in the middle ear of rats. This study analyzed the results from the interaction of the sugarcane-base biopolymer membrane in the middle ear of a rat.

New system of instrument stabilization in laryngeal microsurgery.

Unlabelled: Laryngeal microsurgery is a kind of treatment for various laryngeal diseases. Because of the need of long instruments and delicate maneuvers, involuntary movements represent relevant difficulty and may be responsible for unintended post-operative results.

Aim: This study proposes a new stabilization system, flexible and versatile, which can significantly reduce involuntary movements made by surgeons.

The knowledge of gynecologists and pediatricians from Recife public hospitals about high risk factors for deafness.

Unlabelled: Hearing is one of the main forms of connection between human being and the environment; however, hearing loss is still diagnosed very late in Brazil, which directly interferes with the child's development.

Aim: The aim of this study was to check the knowledge pediatricians and gynecologists have about the risk factors for the deafness, the way they acquired such knowledge and parent education about the subject.

Materials And Methods: We enrolled 119 doctors from three public hospitals of the city of Recife.

The importance of acoustic reflex for communication.

Purpose: The purpose of the study was to compare the speech recognition capacity between listeners with and without acoustic reflex using different types of noises and intensities.

Materials And Methods: We studied 18 women allocated to 2 groups: acoustic reflex present (20 ears) and absent (16 ears). They were presented with 180 disyllable words (90 to each ear), emitted randomly at a fixed intensity of 40 dB above the pure tone average hearing level.

Myringosclerosis in patients with chronic renal failure: comparative analysis with a control group.

Unlabelled: Myringosclerosis is a scar of the tympanic membrane lamina propria, resulting from trauma or inflammation, characterized by proliferation of collagen, hyalinization, calcium and phosphate deposits and cartilaginous or osseous metaplasia of the middle ear mucosa, a sequence that is similar to that taking place in other types of pathologic calcification, common in chronic renal failure (CRF).

Aim: To verify the influence of chronic renal failure on the prevalence of myringosclerosis.

Method: The otoscopic examination was done in 341 chronic renal failure patients and in 356 normal control individuals.

Efficacy of functional endoscopic sinus surgery for symptoms in chronic rhinosinusitis with or without polyposis.

Unlabelled: Functional endoscopic sinus surgery is the preferred treatment for chronic rhinosinusitis currently. Success on symptoms relief and quality of life improvement are the study leading objectives.

Study Design: retrospective clinical trial.

Otomicroscopic and histologic findings of induced myringosclerosis in rats: a critical study of an experimental model.

Unlabelled: Myringosclerosis is characterized by hyaline changes of the lamina propria of the tympanic membrane. Experimental studies have used otomicroscopy or histology to evaluate myringosclerosis in animals, but they do not correlate precisely these two methods.

Aim: The present study evaluates the accuracy of otomicroscopy in the diagnosis of myringosclerosis in rats.
