Background and Objectives: To assess whether the audiological and clinical outcomes of type 0 tympanoplasty (T0) performed using cartilage were comparable with those of ossiculoplasty in patients who underwent canal wall down mastoidectomy (CWDM).Subjects and Methods: This study included patients who had chronic otitis media with cholesteatoma and underwent CWDM with ossiculoplasty involving partial ossicular replacement prosthesis (PORP), total ossicular replacement prosthesis (TORP), or T0. Anatomical success rates and hearing outcomes were analyzed.Results: Seventy-two patients were included in this study; 29 of them underwent CWDM with T0, 27 underwent CWDM with PORP, while 16 underwent CWDM with TORP. The difference in mean improvement in the air-bone gap (ABG) between the groups was not significant. The differences in the rates of ABG closure to ≤10 dB HL (p=0.030) and ≤20 dB HL (p=0.029) were significant. There were significant differences in improvements in the ABG at 3 kHz among the PORP, TORP, and T0 groups.Conclusions: The audiological outcomes of CWDM with ossiculoplasty seemed to be better than those of CWDM with T0 with no significant difference in the incidence of complications following ossiculoplasty and T0.
Improving Accuracy and Reliability of Hearing Tests: An Exploration of International Standards

his study explores the internal standards for hearing tests and benefits of implementing international standard protocols, including the International Organization for Standardization (ISTO) and International Electrotechnical Commission (IEC), and discusses how ISO and IEC standards provide a framework for designing, calibrating, assessing hearing test instruments and methods, and exchanging and comparing data globally. ISO and IEC standards for hearing tests improve accuracy, reliability, and consistency of test results by applying standardized methods and environments. Moreover, they promote international harmonization and data interoperability, enabling information exchange and research collaboration. Those standards for hearing tests are beneficial but have challenges and limitations, such as variation in equipment and calibration, lag in updating standards, variation in implementation and compliance, and lack of coverage of clinical aspects, cultural diversity, and linguistic diversity. These affect the quality and interpretation of test results. Adapting ISO or IEC standards locally would improve their applicability and acceptability, while balancing customization and compatibility with global standards.

Head and neck abscess usually requires hospitalization, intravenous antibiotic therapy, and surgical incision and drainage. Open surgical drainage may result in unsightly scars. We report two cases of a 56-year-old man with a facial abscess and a 47-year-old man with a parotid abscess. The patients were successfully treated with ultra-sound-guided angiocatheter irrigation and drainage without scar. Ultrasound-guided angiocatheter irrigation and drainage can be a simple, safe and effective alternative procedure to open surgery in the management of the se-lected head and neck abscesses.

Mycobacterium massiliense (M. massiliense) is a novel nontuberculous mycobacteria (NTM) and an opportunistic pathogen that lives in the water, soil, food, and air. It is a subspecies of the rapidly growing mycobacteria Mycobacterium abscessus. This atypical pathogen has been reported mainly in patients with lung disease or those undergoing cosmetic or surgical procedures. A 62-year-old woman presented with productive otorrhea for 10 months, no history of surgery, and chronic otitis media. M. massiliense was identified from a tissue specimen using real-time polymerase chain reaction for NTM (Biosewoom, Seoul, Korea), and NTM was identified by acid-fast bacilli culture. Successful treatment consisted of clarithromycin for 4 months. No other case of chronic otitis media related to M. massiliense has been reported. This is the first confirmed case of chronic otitis media caused by M. massiliense in a healthy adult in South Korea. (Korean J Med 2020;95:276-280)

Hearing thresholds provide essential information and references about the human auditory system. This study aimed to identify changing trends in distributions of hearing threshold levels across ages by comparing the International Organization for Standardization (ISO) 7029 and newly available data after publishing ISO 7029. To compare ISO 7029 and newly available hearing threshold data after publishing ISO 7029, four country-specific datasets that presented average hearing threshold levels under conditions similar to ISO 7029 were utilized. For frequencies between 125 Hz and 8,000 Hz, the deviations of hearing threshold values by ages from the hearing threshold of the youngest age group for each data point were utilized. For frequencies from 9,000 Hz to 12,500 Hz, the median threshold information was utilized. Hearing threshold data reported after publishing ISO 7029 from the four countries were mostly similar to the ISO 7029 data but tended to deviate in some age groups and sexes. As national hearing threshold trends change, the following ISO 7029 revision suggests the need to integrate hearing threshold data from different countries.
