The causes of mixed hearing loss are presented based on its embryonic development, audiological tests, and high-resolution computed tomography (CT) imaging. This case describes a 35-year-old female patient diagnosed due to bilateral conductive hearing loss. The patient complained of a significant deterioration of hearing and speech understanding lasting for several months. Preoperative audiometric work-up revealed air-bone gap with the presence of Carhart's notch characteristic for otosclerosis. In CT scans otospongiotic focus was confirmed and the absence of stapedius muscle, its tendon, and pyramidal eminence was discovered. The patient underwent stapedotomy with good hearing result after healing. Understanding the stapedius muscle's development process is essential to comprehend the reason for its failure - the absence of the stapedius muscle results in exposure to acoustic trauma. Patients may experience hypersensitivity to sound, although it was not discovered in the described patient. High-resolution CT is a handy tool for analyzing congenital malformations of the middle ear. The absence of the stapedius muscle may also be indicated by other anatomical variations of the middle ear detected with high-resolution computed tomography images. The absence of the stapedius muscle may coexist with otosclerosis. Detailed in-depth analysis of high-resolution computed tomography images is the only tool to assess for stapes muscle defects without surgical intervention.</p>","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, various innovations have made surgical training more realistic. Saturated salt solution (SSS) and urea methods are useful for plastic surgery training, because they better preserve the color and texture of soft tissues than formalin fixation (FA). Microvessels are invisible to the naked eye, and in this study, we visualized skin perforators by injecting dye into the flaps of nutrient vessels during hand and foot surgery. During each CST session, the instructor used three cadavers for demonstration. From 2017 to 2021, these cadavers were not stained, whereas from 2022 to 2023, the cadavers were stained to enhance the visualization of nutrient and perforating vessels. We compared the self-rated skill gains of participants who observed demonstrations on unstained cadavers from 2017 to 2021 and participants who observed demonstrations on stained cadavers from 2022 to 2023. Among 36 participants from the 2022–2023 group, 28 rated the staining of nutrient vessels and perforating branches as adequate. Of 32 participants, 29 preferred the use of dyed cadavers during training. Trainee skill increase for the digital artery flap, reverse digital artery flap, and dorsal metacarpal artery perforator flap was significantly higher in 2022–2023 (with stained cadavers) than in the earlier course without stained cadavers.

The atypical arteries, related arteries, and adjacent cervical and brachial plexuses were macroscopically examined in a 98-year-old Japanese female cadaver donated to The Nippon Dental University for medical education and research. The atypical deep branch of the transverse cervical artery originated from the internal thoracic artery and passed through between the C5 and C6 roots, in close contact with the C5 and C6 junction, to reach the dorsal side of the brachial plexus. The right subclavian artery exhibited a high arch-shaped coursing and traveled approximately 18 mm higher than the left subclavian artery. This atypical transverse cervical artery exhibits a combination of rare variations in its origin and course. The previous reports revealed that the transverse cervical artery arising from the proximal part of the subclavian artery tends to pass the lower part of the brachial plexus. However, this does not apply to the present case, implying that this atypical artery develops in a different manner from those previously described. Furthermore, the high arch-shaped subclavian artery in this case presumably arose by the suspension of the atypical transverse cervical artery at the C5 and C6 roots junction in a pulley-like structure. Clinicians performing pre- and intraoperative evaluations of neck surgery and catheterization of related arteries should consider that congenital anatomic variations in the transverse cervical artery may have cause anomalous subclavian artery coursing.</p></div>","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":"100 3","pages":"375 - 380"},"PeriodicalIF":1.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143051371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
