An inter-observer assessment of mastoid pneumatization and degree classification using sigmoid sinus: comparing two levels of temporal bone computed tomograms.

BACKGROUND: The degree of mastoid pneumatization of the temporal bone (TB) has been implicated in the pathogenesis of TB diseases and surgical implications, and planning of a few otologic surgeries. However, there is lack of consensus in the classification of the degree of pneumatization. This study aimed to suggest a simple, quick, and less-burden classification system for assessing and rating the degree of pneumatization by comparing two levels of TB computed tomographs (CTs) using the SS as a reference in an inter-observer assessment among otologists. METHODS: This was a randomized pilot survey among otologists. A questionnaire consisting of different axial CTs of TB taken at two levels: the level of malleoincudal junction (MIJ) and the level of lateral semicircular canal (LSCC), with different pneumatization patterns, was used to assess participants' impressions of the degree of pneumatization. The terms "hypo-," "moderate," "good," and "hyper-" pneumatization were listed as options to rate their impressions on the degree of mastoid pneumatization of the TB images using the SS as a reference structure. Likert scale was used to assess their level of agreement or disagreement with using SS as a reference in evaluating mastoid pneumatization. RESULTS: Participants who correctly rated images taken at the level of LSCC according to their respective degree of pneumatization were significantly higher (p < 0.05) regardless of their year of experience compared to those that correctly rated corresponding images taken at the level of MIJ. A 76% positivity in their level of agreement with the use of sigmoid sinus in evaluating mastoid pneumatization was observed on the Likert-scale chart. CONCLUSION: Findings from this study suggest that evaluating air cells around the SS at the level of LSCC on CTs could be easier in assessing and classifying the degree of mastoid pneumatization.

Audiologists' Perceptions of Hearing Healthcare Resources and Services in South Africa's Public Healthcare System.

Background: Hearing loss poses a significant burden globally. Its prevalence is exceptionally high in countries across the African region, where healthcare resources and services remain inaccessible. This study aimed to describe audiologists' perceptions regarding hearing healthcare resources and services within South Africa's public healthcare system. Methods: A national self-developed telephonic survey was conducted with audiologists in public healthcare system hospitals across South Africa, with the final sample comprising 100 audiologists. Results: Most (82%) audiologists indicated that their hospitals did not have adequate hearing healthcare resources to render efficient audiology services to patients. Binaural amplification devices (invasive and non-invasive) for adults with bilateral hearing loss who adhered to the criteria for these devices were perceived to be unavailable in most hospitals. Audiologists also perceived that universal newborn hearing screening services, adult aural rehabilitation services, and follow-up care for all hearing devices post-warranty expiration were limited. Conclusion: Efforts should be made to upsurge hearing healthcare resources, including increasing the financial budgets allocated to audiology resources so that increased diagnostic and screening audiology equipment and hearing devices can be procured where required, and additional audiologists can be employed within the South African public sector hospitals where needed.

Perceptions of Telehealth Services for Hearing Loss in South Africa's Public Healthcare System.

Telehealth promises increased access to hearing healthcare services, primarily in areas where hearing healthcare resources are limited, such as within the South African public healthcare system. Telehealth for hearing healthcare is especially important during the COVID-19 pandemic, where physical distancing has been essential. This study aimed to describe audiologists' perceptions regarding telehealth services for hearing loss within South Africa's public healthcare system. This study was divided into two phases. During Phase 1, 97 audiologists completed an electronic survey regarding their perceptions of telehealth for hearing loss within South African public sector hospitals. Synchronous virtual focus-group discussions were conducted during Phase 2. Results indicated that audiologists recognized telehealth services' potential to improve hearing healthcare efficiency within the public sector, and most (84.1%) were willing to use it. However, telehealth's actual uptake was low despite almost doubling during the COVID-19 pandemic. Prominent perceived barriers to telehealth were primarily related to hospital resources, including the unavailability of equipment for the remote hearing/specialized assessments, internet-related barriers, and limited IT infrastructure. An increased understanding of telehealth in South Africa's public healthcare system will assist in identifying and in improving potential barriers to telehealth, including hospital resources and infrastructure.

Tympanoplasty with an Intact Stapes Superstructure in Chronic Otitis Media.

BACKGROUND: The objective of our study was to ascertain the functional results in terms of air bone gap (ABG) closure over 4 frequencies (0.5, 1, 2, 3 kHz) in patients with chronic otitis media (COM) that underwent tympanoplasty in the presence of a mobile stapes superstructure, and in particular excluding those cases in which the malleus was used in the reconstruction. METHODS: A retrospective review of our database between January 1, 2006 and June 1, 2018 identified all cases that underwent one of 3 reconstructive options: the classic Type III tympanoplasty in an open-cavity setting; the "stapes augmentation" (SA) type reconstruction where the stapes superstructure is augmented to the drum by an interposing partial ossiculoplasty of either autologous bone, cartilage, or prosthetic material; and the use of a total articular replacement prosthesis (TORP) from the stapes footplate to the drum in the presence of an intact superstructure. RESULTS: A total of 116 procedures in 112 patients were identified with a mean ABG reduction from 27 dB to 21 dB (P < .05). There was no significant difference in the mean post-operative ABG result between Type III (19.21 dB), TORP+ (24.90 dB), or SA (20.94 dB) reconstructions (P = .368). Overall, an ABG ≤ 20 dB or "surgical success" was achieved in 56% (n = 65) of cases. Only 20% (n = 23) of cases had "failure" or a post-operative ABG >30 dB. CONCLUSION: Tympanoplasty with an intact stapes superstructure in COM is expected to provide acceptable levels of surgical success. We did not identify any particular risk factors associated with improved outcome.

Health-related quality of life in South African children who use cochlear implants.

Objective: To describe health-related quality of life (HRQoL) outcomes of school-going paediatric cochlear implant (CI) recipients in a South African cohort from the perspectives of parents.Design: Parents of school-going CI recipients completed the Children with Cochlear Implants: Parental Perspectives (CCIPP) CI-specific HRQoL questionnaire. The effect of different demographic variables on HRQoL outcomes was also determined.Study sample: The study sample included 54 parents of school-going (mean age = 12.2 years; SD = 3.6; range = 6.6-18.3 years) CI recipients with at least six months CI experience.Results: Children's communication and general functioning with a CI received the most positive parental ratings. Among a number of confirmed statistically significant (p < 0.05) associations between HRQoL outcomes and demographic variables, pre-lingual onset of deafness was linked to better HRQoL in terms of general functioning and well-being. While shorter duration of deafness and unilateral implantation were associated with higher parental ratings for self-reliance and well-being respectively, longer duration of CI use was linked to improved HRQoL outcomes in terms of general functioning.Conclusion: Parents assigned positive ratings to their child's HRQoL. This exploration of children's HRQoL related to their CIs contributes to evidence-based paediatric CI services that promote optimal psychosocial outcomes.

Parent-perceived challenges related to the pediatric cochlear implantation process and support services received in South Africa.

OBJECTIVE: To determine and describe parent-perceived challenges related to the pediatric cochlear implantation process and support services received. METHOD: A multicenter survey study across six cochlear implant (CI) programs in South Africa (SA) was conducted. The study sample included 82 parents of pediatric (≤18 years) CI recipients with at least 12 months CI experience. A self-administered questionnaire was developed for the purpose of this study, exploring parental challenges regarding the CI process, education of their implanted children and the support services received. RESULTS: The financial implications of cochlear implantation, including CI device maintenance, were identified by parents as the most prominent challenge. Financing issues were the highest scoring reason that attributed to the delay between diagnosis of hearing loss and cochlear implantation, as well as the greatest barrier to bilateral implantation. Parent-perceived educational challenges included finding adequate educational settings specific to the individual needs of their child and a shortage of trained teachers equipped to support children with CIs. The presence of one/more additional developmental conditions and grade repetition were associated with more pronounced parent-perceived educational challenges. Parents considered speech-language therapy as the most critical support service for their implanted children to achieve optimal outcomes, while parent guidance was indicated to be the most critical support service required for parents of pediatric CI recipients. CONCLUSION: A greater understanding of parent-perceived challenges will guide CI professionals to promote optimal outcomes, evidence-based service delivery and on-going support to pediatric CI recipients and their families. Study results imply a call for action regarding financial and educational support for pediatric CI recipients in SA.

Providers' perspectives on the best practices for HIV prevention for men who have sex with men in Berlin, Germany: lessons for policy and prevention.

Using qualitative data via providers' perspectives, the goal of this study was to identify strengths and weaknesses in the current approaches being used to prevent onward transmission of HIV among men who have sex with men (MSM) in Berlin, Germany. In 2013, 18 participants from 10 organizations who provide direct outreach or services to MSM were interviewed (30-75 minutes). With regard to strategies and services that individuals believed contributed to the organization's success, we identified five themes: (1) Having staff and volunteers to "match" the target population, (2) Embracing homosexuality and gay identity, (3) Being invested in the cause, (4) Coordination of services to avoid overlap and duplication, and (5) Seeing eye-to-eye with the target population. Finally, with regard to areas in which organizations felt they could use improvement (i.e., continuing challenges), we identified three themes: (1) Insufficient funding and resources, (2) Insufficient services, and (3) HIV stigma, homophobia, and shifting attitudes about HIV. This study informs HIV prevention approaches in Berlin, Germany as well as other urban centers where MSM are disproportionally affected by the HIV epidemic.

Complicated sinusitis in a developing country, a retrospective review.

OBJECTIVES: The aim of our study was to assess the incidence rate, mode of presentation, treatment and outcome measures associated with complicated sinusitis in our developing world setting. Additionally we had hope to identify possible patterns or predisposing factors that may assist us in decreasing the significant morbidity and mortality associated with this serious disease. METHOD: A retrospective chart review was performed on all patients treated for complicated sinusitis at 3 referral hospitals in Durban South Africa between January 2006 and September 2009. RESULTS: A total of 220 patients were identified including 138 patients with orbital complications only and 82 with intracranial complications with or without orbital manifestations. We report on the demographics, mode of presentation, microbiology, impact on resources, management and mortality of the study group. The incidence rate was found to be 5.83 per million, the most common risk factors associated with intracranial complications, a persistent headache beyond 1 week and referral from a rural rather than urban area (OR 3.24). We found a high mortality rate of 20.7% in those patients with intracranial complications of their sinusitis. CONCLUSIONS: Complicated sinusitis is still far too common in the developing world with young adolescent males most at risk. A high index of suspicion must be maintained in detecting orbital as well as intracranial extension of disease and appropriate referral for investigation and management swift and aggressive in preventing extensive morbidity and mortality.
