Translation and cultural adaptation of "Glasgow Children's Benefit Inventory" into Brazilian Portuguese.

Objective: Translate and cross-culturally adapt into Brazilian Portuguese the Glasgow Children's Benefit Inventory instrument used for the quality-of-life assessment after pediatric ENT interventions.

Method: This is a methodological study of translation and cross-cultural adaptation of the GCBI instrument following seven stages: 1) Translation of two versions by two independent translators, 2) Elaboration of a consensual synthetized version, 3) Assessment of the synthetized version by experts, 4) Assessment by the target audience, 5) Back-translation, 6) Pilot study and 7) Use of the instrument. The final version of the instrument was answered by a sample of 28 people responsible for children aged from 2 to 7 years, submitted to tonsillectomy between January 2019 and December 2021, in a public hospital in Porto Alegre.

Objective: To analyze the contralateral ear (CLE) of patients with cholesteatoma and to correlate the cholesteatoma growth pattern in the affected ear with the findings in the CLE.

Methods: Videotoscopy of both ears in 432 patients with cholesteatomas classified as posterior epitympanic (PEC), posterior mesotympanic (PMC), two routes, or undetermined. Tympanic membrane (TM) retractions were classified by location and severity and TM perforations according to signs of previous TM retraction.

Cholesteatoma labyrinthine fistula: prevalence and impact.

Introduction: Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood.

Tinnitus and sound intolerance: evidence and experience of a Brazilian group.

Introduction: Tinnitus and sound intolerance are frequent and subjective complaints that may have an impact on a patient's quality of life.

Objective: To present a review of the salient points including concepts, pathophysiology, diagnosis and approach of the patient with tinnitus and sensitivity to sounds.

Methods: Literature review with bibliographic survey in LILACS, SciELO, Pubmed and MEDLINE database.

Tinnitus in Elderly Individuals: Discomfort and Impact in the Quality of Life.

 Tinnitus is a symptom that affects mainly the elderly and can negatively influence their quality of life.  The objective of our study is to evaluate the existence of a relationship between the quality of life and the impact caused by tinnitus in elderly individuals, considering the age and gender variables.  We conducted a cross-sectional study in elderly people of both genders who participate in the extension activities at the university.

Pitch and Loudness Tinnitus in Individuals with Presbycusis.

Characteristics of 419 patients with acquired middle ear cholesteatoma.

Introduction: Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease.

Cholesteatoma growth patterns: are there audiometric differences between posterior epitympanic and posterior mesotympanic cholesteatoma?

The objective of this is to verify whether the hearing impairment caused by posterior epitympanic differed from that caused by posterior mesotympanic cholesteatomas by a cross-sectional study. We evaluated 264 ears of patients with cholesteatoma, who had not been subjected to ear surgery. Otoendoscopy and pure-tone audiometry were performed.

The contralateral ear in cholesteatoma.

Middle ear cholesteatoma has been extensively studied. Theories of cholesteatoma pathogenesis involving previous tympanic membrane retraction are the most widely accepted, but the contralateral ear in patients with cholesteatoma remains unstudied. This study aimed to investigate the contralateral ear in patients with cholesteatoma, and to determine whether the characteristics of it differ according to patient age and cholesteatoma growth patterns.

Study Design: Cross-sectional comparative study.

Setting: Tertiary hospital.

Tomographic evaluation of the contralateral ear in patients with severe chronic otitis media.

Unlabelled: Some studies indicate a bilateral tendency of chronic otitis media. It is believed that the contralateral ear can provide evidences of the route of formation of ear disease in the most affected, be a parameter of Eustachian tube function and predict successful treatment. The CT scan is an excellent test to evaluate the structures of the temporal bone and the changes resulting from otitis media.
