Title Alternative Questionnaire survey of junior and mid-career otolaryngologists' attitudes towards clinical research

Abstract  Introduction : Clinical research is crucial for the advancement of medicine, but modern otolaryngologists' attitudes regarding clinical research have not been known. This study was conducted to survey the background, knowledge, and interest in clinical research among junior and mid-career otolaryngologists.
 Methods : A questionnaire survey was distributed to 34 otolaryngologists with ≤15 years' clinical experience working at Okayama University and its affiliated facilities. The respondents were divided into junior (non-specialists) and mid-career otolaryngologists (specialists) based on whether they were board-certified otolaryngologists. The survey assessed their background, understanding, and interest in clinical research.
 Results : Twenty-nine otolaryngologists (83%) responded (10 junior and 19 mid-career otolaryngologists). There was significant individual variation in their interest and knowledge of clinical research. However, approximately half of the respondents indicated that they were not interested in and/or had never engaged in clinical research.
 Conclusion : The data collected by this survey contribute to our understanding of the current state of clinical research engagement among junior and mid-career otolaryngologists, and they can serve as a basis for exploring future strategies to increase this engagement.

Abstract Temporal bone computed tomography (CT) is frequently performed for pediatric patients with ear diseases. Advances in CT technology have improved diagnostic imaging quality, but reduction of radiation exposure remains a goal. We evaluated the potential for radiation dose reduction in temporal bone CT examinations using porcine ear ossicles and a photon-counting detector CT system. Three scans of the bilateral temporal bone were performed on each of three pig cadaver heads. In each of seven successive imaging sessions, the radiation dose was reduced by an additional one-seventh of the recommended dose (RD). Two board-certified radiologists independently scored the resulting images on a scale of 1 to 5 points, where 5 represented the image quality at the RD. Images scoring ≥4.5 points were considered acceptable. Noise was assessed in a 2-cm-diameter region near the ear ossicles, and standard deviation was measured for each of the seven decrements from the RD. As the radiation dose decreased, the noise progressively increased, and visual assessment scores progressively decreased. Acceptable image scores were obtained at six-sevenths (4.9), five-sevenths (4.8), four-sevenths (4.7), and three-sevenths (4.6) of the RD. Thus, acceptable porcine temporal bone CT images were obtained with a radiation dose reduction of approximately 50%.

Abstract Middle-ear salivary gland choristoma (SGCh) is a rare, benign tumor that causes conductive hearing loss owing to middle-ear morphological abnormalities. Early diagnosis is challenging, and surgical resection is indispensable for a definitive diagnosis. We report the case of a 3-year-old boy diagnosed with middle-ear SGCh during the follow-up period for left-sided hearing loss discovered at newborn hearing screening (NHS). Long-term follow-up after the NHS result, subsequent computed tomography/magnetic resonance imaging, and surgical resection led to its relatively early diagnosis and treatment.

Abstract Choosing the optimal side for cochlear implantation (CI) remains a major challenge because of the lack of evidence. We investigated the choice of the surgery side for CI (i.e., the better- or poorer-hearing ear) in patients with asymmetric hearing. Audiological records of 74 adults with a unilateral hearing aid who had undergone surgery at Okayama University Hospital were reviewed. The definition of ‘better-hearing ear’ was the aided ear, and the unaided ear was considered the poorer-hearing ear. We performed a multiple regression analysis to identify potential predictors of speech recognition performance after unilateral CI in the patients. Fifty-two patients underwent CI in the poorer-hearing ear. The post-Ci bimodal hearing rate was far higher in the poorer-ear group (77.8% vs. 22.2%). A multivariate analysis revealed that prelingual hearing loss and the patient’s age at CI significantly affected the speech recognition outcome (beta coefficients: 24.6 and −0.33, 95% confidence intervals [11.75-37.45] and [−0.58 to −0.09], respectively), but the CI surgery side did not (−6.76, [−14.92-1.39]). Unilateral CI in the poorer-hearing ear may therefore be a reasonable choice for adult patients with postlingual severe hearing loss, providing a greater opportunity for postoperative bimodal hearing.
