OBJECTIVE:To demonstrate the surgical technique and audiological results of a middle ear implant for restoring hearing in patients with bilateral aural atresia and microtia with conductive or mixed hearing loss. MATERIALS and METHODS:In this prospective study, 12 subjects aged 12 years and older presenting with hearing loss and bilateral congenital aural atresia underwent surgical insertion of a middle ear implant. The patients underwent tympanomastoidectomy with a wide opening of the attic and preservation of the roof of the atresic tympanic bone to expose the middle ear and position the floating mass transducer of the implant.RESULTS: There were no intraoperative or postoperative complications. The hearing threshold averages in a free field were 53.5 dB preoperatively and 25.6 dB postoperatively. Monosyllabic word recognition averaged 61% preoperatively and 91.3% postoperatively. The average speech perception in quiet conditions during the hearing in noise test improved from 67.11 dB to 45.99 dB, and the signal-to-noise ratio improved from 5.64 to 1.31. CONCLUSION:The tested system is an excellent option for auditory rehabilitation of conductive hearing loss due to bilateral ear atresia. The surgery is well structured and safe and provides several alternatives to the surgeon, which is valuable in difficult cases.

Our results suggest that most patients with EEC syndrome and middle ear cholesteatoma should be considered for a canal wall down mastoidectomy due to extensive disease and a high rate of recidivism. In addition, a high percentage of postoperative stenosis of the external auditory canal was found in this group.

Objective: To assess the health utility scores of Thais with hearing loss, which can be used as a reference value for assessing health-related quality of life and economic evaluations in any interventions among hearing-impaired persons in Thailand. Material and Methods: All hearing-impaired persons who visited Songklanagarind Hospital between January and June 2019 were recruited for the study. The demographic and clinical data of the participants including gender, age, and type and degree of hearing loss were collected. A health-related quality of life interview was conducted using the EuroQoL five-dimensional questionnaire, Thai version. Independent t-test and multiple linear regression analysis were performed to assess which factors were associated independently with the health utility scores. Results: One hundred and eleven participants, 46 males and 65 females, ranging in age from 22 to 92 years, were recruited for the study. The average health utility scores were 0.81 and 0.86 for subjects not using and using hearing aids, respectively, similar to the results from other nations. The average health utility score of subjects with underlying diseases (0.79) was lower than the average health utility score of subjects without underlying diseases (0.87) with statistical significance (p-value=0.038). Additionally, the pure tone average in the better ear was the only variable significantly associated with the health utility scores (regression coefficient: -0.004, p-value=0.002). Conclusion: The average health utility scores among hearing-impaired Thais were 0.81 and 0.86 for subjects not using and using hearing aids, respectively.

Purpose Schirmer Strips and Conjunctival swabs are used in ophthalmology for tears and fluids collection. During the COVID-19 pandemic, one of the biggest challenges is accurate diagnosis, and it is known that, in some cases, ocular manifestations are one of the first symptoms. In this context, this study has the objective of raising scientific evidence that highlights the use of Schirmer strips and conjunctival swabs as a method of sample collection for viral analysis to support future research on this theme. Methods A literature search was conducted in the PubMed, Web of Science and BVS databases, following the Scoping Review protocol defined by Joanna Briggs Institute (JBI) after the guiding question “Is it possible to detect viruses on the ocular surface with Schirmer Test and/or conjunctival swab?”.Results A total of 418 studies were identified, and after discerning analysis, 36 English written studies were selected. Three researchers analyzed studies after virus research, collection methods, and sample analysis. Publications were mainly on adenovirus, herpes simplex virus and SARS-CoV-2, and there is also evidence of ocular detection of more viruses types. Conjuntival swab analyzed through Polymerase Chain Reaction (PCR) or Reverse Transcriptase-PCR (RT-PCR) were the most used methods.Conclusions Studies have generally been conducted to understand viral infection, to develop accurate diagnostic methods and to follow the patients’ response to treatment. Most studies were performed with a small number of patients and lacked clear definitions of collection time and viral persistence since the onset of diseases. Viruses can be detected on the ocular surface through the analysis of Schirmer strips and conjunctival swabs. However, additional studies with larger populations and time permanence are necessary to develop more assertive conclusions on the theme.
