Objective: The aim was to study the relationship between the labyrinthine portion (LP) of the facial canal and the cochlea in human inner ear molds and temporal bones using micro-CT and 3D rendering. A reduced cochlea-facial distance may spread electric currents from the cochlear implant to the LP and cause facial nerve stimulation. Influencing factors may be the topographic anatomy and otic capsule properties. Methods: An archival collection of human temporal bones underwent micro-CT and 3D reconstruction. In addition, cochlea-facial distance was assessed in silicone and polyester resin molds, and the association between the LP and upper basal turn of the cochlea was analyzed. Results: Local thinning of the otic capsule and local anatomy may explain the development of cochlea-facial dehiscence, which was found in 1.4%. A reduced cochlea-facial distance was noted in 1 bone with a superior semicircular canal dehiscence but not in bones with superior semicircular canal “blue line.” The otic capsule often impinged upon the LP and caused narrowing. Conclusion: Micro-CT with 3D rendering offers new possibilities to study the topographic anatomy of the human temporal bone. The varied shape of the cross-section of the LP could often be explained by an “intruding” cochlea.

Aortopulmonary Collateral

Background Major aortopulmonary collateral arteries (MAPCAs), as seen in patients with pulmonary atresia, are arteries that supply blood from the aorta to the lungs and often require surgical intervention. To achieve complete repair in the least number of interventions, optimal imaging of the pulmonary arterial anatomy and MAPCAs is critical. 3D virtual reality (3D-VR) is a promising and upcoming new technology that could potentially ameliorate current imaging shortcomings. Methods A retrospective, proof-of-concept study was performed of all operated patients with pulmonary atresia and MAPCAs at our center between 2010 and 2020 with a preoperative computed tomography (CT) scan. CT images were reviewed by two congenital cardiac surgeons in 3D-VR to determine additional value of VR for MAPCA imaging compared to conventional CT and for preoperative planning of MAPCA repair. Results 3D-VR visualizations were reconstructed from CT scans of seven newborns where the enhanced topographic anatomy resulted in improved visualization of MAPCA. In addition, surgical planning was improved since new observations or different preoperative plans were apparent in 4 out of 7 cases. After the initial setup, VR software and hardware was reported to be easy and intuitive to use. Conclusions This study showed technical feasibility of 3D-VR reconstruction of children with immersive visualization of topographic anatomy in an easy-to-use format leading to an improved surgical planning of MAPCA surgery. Future prospective studies are required to investigate the clinical benefits in larger populations.

Human Ontogenesis

Objectives - to present topographic and anatomic characteristics of the larynx relationship with neck organs and structures in the intermediate fetal period of human ontogenesis. Material and methods. The study included 85 organocomplexes of the fetuses neck of both sexes, from the 14th to the 27th week of development. The study material was divided into 2 age periods: the first group - fetuses aged 14-20 weeks; the second group - 21-27 weeks. The classical morphological techniques were used: (macromicroscopic preparation, modified method of saw cuts according to N.I. Pirogov, histotopographic method). Results. Larynx syntopy with thyroid gland, cervical esophagus, thymus, submandibular glands was described in detail. Larynx skeletotopy with incisurae jugularis sterni, cervical vertebrae, hyoid bone, mandible was described quantitatively. Conclusion. The data, obtained as a result of the study, supplement the data on the topographic anatomy of larynx and some neck organs and structures in the prenatal period of human ontogenesis. The revealed formation features of larynx and other neck organs and structures topography can be used in the study of intravital anatomy.

Abstract Aim Fascial groin anatomy remains a conundrum. In particular, a clear anatomical allocation of the correct extraperitoneal dissection planes and spaces in total extraperitoneal endoscopic hernia surgery (TEP) has not yet agreed upon. The differing anatomical concepts are reflected by the variability of surgical approaches, the considerably long learning curves and subsequent complications. Thus, the aim of this study was to reassess the topographic anatomy of the groin region providing a basis to standardize the surgical steps of TEP according to clearly defined anatomical landmarks. Material and Methods Video analysis of intraoperative surgical anatomy of groin hernia patients was correlated with the findings retrieved by macroscopic anatomical studies. The groin region of formalin fixed body donors was subjected to a stepwise dissection exposing the fascial system of the abdominal wall layer-by-layer and via different angles. Selected areas of interest were processed for histological study. Surgically relevant anatomical landmarks were defined and termed according to the most appropriate anatomical nomenclature. Results The essential surgical dissection steps during TEP could be related to specific anatomical landmarks extending within the extraperitoneal space of the ventral and dorsolateral abdominal wall. The definition of fascial structures and interfaces and the identification of structures at risk allowed the identification of correct dissection planes for mesh placement. Conclusions Our study helps to clarify the definition and nomenclature of anatomical key structures required for a standardized description of TEP in a simplified model. The data may contribute to reduce complications and improve surgical teaching and training.
