To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. The topics were divided into 2 parts: 1) Diagnosis - audiologic and radiologic; 2) Treatment - hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices - bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

RESUMO Objetivo Descrever os benefícios nos limiares auditivos e no desempenho de reconhecimento de sentenças no silêncio e no ruído em indivíduos com a adaptação unilateral do Sistema Ponto®. Métodos Estudo observacional, retrospectivo, de seguimento longitudinal. A casuística foi composta por fontes de dados secundários de dez indivíduos com perda auditiva condutiva ou mista, que foram submetidos à cirurgia com o Sistema Ponto®. Os resultados foram analisados nas seguintes condições: a) pré-cirúrgicas: sem AASI; com AASI por condução aérea ou óssea e com o processador Ponto Pro® acoplado a uma banda elástica; b) pós-cirúrgicas: na ativação e após seis meses de uso. Resultados Os limiares da audiometria tonal por conduções aérea e óssea mantiveram-se estáveis após a cirurgia, enquanto os limiares auditivos em campo livre e o reconhecimento de fala no silêncio e no ruído foram estatisticamente melhores na ativação e após seis meses de uso do Sistema Ponto®. Não houve diferença nos resultados com os indivíduos utilizando o Sistema Ponto® com a banda elástica e após a cirurgia. Conclusão O Sistema Ponto® propiciou benefício nas habilidades auditivas de detecção em todas as frequências testadas, assim como no reconhecimento de sentenças no silêncio e no ruído.

Purpose: To determine the prevalence of SARS-CoV-2 in tear samples and to investigate whether it correlates with ocular findings and patients’ prognosis in Brazil. Methods: Tears were collected using Schirmer strips (SS) and conjunctival swabs (CS) from patients hospitalized with laboratory-confirmed SARS-CoV-2 infection. Samples were analyzed using qRT-PCR. Demographic and clinical data, ocular symptoms, and Schirmer tests (ST) were collected from patients. Charlson Comorbidity Index (CCI) was used to rate comorbidities, and patients were monitored until hospital discharge or death. Results: There were 61 hospitalized patients, 33 of which were diagnosed with COVID-19. Within the confirmed COVID-19 patients, SARS-CoV-2 was detected in 18.2% (n = 6) of CS and 12.1% (n = 4) of SS samples. Subjective and objective parameters for dry eye syndrome (e.g., ST COVID-19: 8.3 ± 6.4mm, non-COVID-19: 8.9 ± 6.6mm, p > 0.05) were comparable between COVID-19 (n = 33) and non-COVID-19 patients (n = 28). Among the 16 COVID-19 patients exhibiting ocular symptoms, only tearing was reported significantly more frequently when tear samples were positive for SARS-CoV-2 (p < 0.05). Strikingly, patients whose tears tested positive for SARS-CoV-2 had significantly inferior CCI (pos.: 34.0 ± 31.8%, neg.: 67.6 ± 36.4%, p < 0.05) and higher mortality rates (pos.: 50.0%, neg.: 7.4%, p < 0.01). Conclusions: SARS-CoV-2 was detected with a prevalence of 18.2% on the ocular surface. Decreased CCI and increased mortality rate in the positive tear group suggests that viral detection may relate to prognosis and highlight the need of personal protective measures for healthcare professionals. Most of the patients, regardless of COVID-19 diagnosis, had low tear production and eye discomfort, possibly pointing to the need for artificial tear use during hospitalization.

Objective: To describe the audiological results and complications following active middle ear implant (AMEI) surgery in users with bilateral ear atresia. Study Design: Observational and retrospective longitudinal follow-up. Setting: A tertiary referral hospital for hearing rehabilitation and craniofacial malformations. Patients: Medical records of 27 patients with bilateral congenital aural atresia (34 ears) who underwent surgery for AMEI were reviewed. Data were analyzed using descriptive and inferential statistics. The alpha error was assumed to be 5%. Outcome Measures: Medical and technical complications and audiological results were observed during follow-up. Results: The median postoperative follow-up was 37.5 months (27.7–75.5 mo). Medical or technical complications occurred in 35.3% (n = 12) of patients during follow-up, 14.7% (n = 5) required surgical revision. The auditory thresholds in the free field improved from 53.75 dB (46.87–56.25) to 25 dB (21.25–32.5) after 6 months using the AMEI (p < 0.001) and remained stable till the last audiological evaluation (22.5: 21.25 26.25). Compared with the preoperative results, all speech perception tests also showed the benefits of AMEI at 6 months postoperatively and in the last audiological evaluation. Conclusions: Monitoring the use of AMEI in this sample demonstrated the safety of these implants compared with data available in the literature. The rates of medical and technical complications were consistent with data published by other groups. Finally, the audiological results remained stable during follow-up.

Objective: The video otoscope has already proven to be useful for the diagnosis of several pathologies, so the objective of this study was to evaluate the diagnostic accuracy of the video otoscope in cases of tympanic membrane perforation.Methods: This is a diagnostic accuracy study performed at the hearing health division of a tertiary-level referral hospital. Patients older than 8 years of age who had any symptom that could be related to perforation (otalgia, otorrhea, tinnitus, and/or hypoacusis) were invited to participate in the study. Participants were evaluated by three different diagnostic methods (otomicroscope, conventional otoscope, and video otoscope) performed by three different evaluators in a blind fashion. The microscope was considered the reference standard.Results: 176 patients were evaluated, totaling 352 tympanic membranes. Twenty-seven tympanic membrane perforations were diagnosed by the microscope, a prevalence of 7.7%. The video otoscope showed a sensitivity of 85.2% (95% CI 81.5%-88.9%), specificity of 98.1% (95% CI 96.7%-99.5%) and accuracy of 97.1% (95% CI 95.4 %--98.8 %). The conventional otoscope showed a sensitivity of 96.3% (95% CI 94.3--98.3), specificity of 98.8% (95% CI 97.7-99.9) and accuracy of 98.6% (95% CI 97.4--99.8). The Kappa value between the microscope and the video otoscope was 0.8 and between the microscope and the conventional otoscope was 0.9. Regarding the participants' perception, 53.4% (p < 0.001) considered the video otoscope as the best method for understanding the tympanic membrane condition presented by them.Conclusions: The video otoscope showed relevant sensitivity and specificity for clinical practice in the diagnosis of tympanic membrane perforation. Moreover, this is an equipment that can facilitate the patient's understanding of the otologic pathology presented by him/her. In this regard, this method may be important for better patient compliance, requiring further studies to evaluate this hypothesis. Level of evidence: Is this diagnostic or monitoring test accurate?

Objective: To describe the post-operative complications and audiological results related to percutaneous bone-anchored hearing devices.Methods: A retrospective review was conducted of 44 patients with bilateral conductive or mixed hearing loss who were implanted with unilateral Baha Connect or Ponto devices. A generalised linear model for repeated measurements was used.Results: Twenty patients were Baha Connect users, and 24 were implanted with Ponto devices. Twenty-seven patients experienced complications. No fewer complications were found in the group of patients using longer abutments. When we compared the frequency of complications between Ponto and Baha Connect users, there was no statistically significant difference (p = 0.90). Free-field hearing thresholds were statistically significantly improved when we compared pre- and post-operative results (p < 0.001). Average speech perception also improved (p < 0.001).Conclusion: Despite percutaneous bone-anchored hearing devices having a high rate of complications, they provide significant audiological benefits.
