Background: It is still far away from most of us in that it requires complex 3D modeling.
Aims/objectives: To investigate a more precision, simple, convenient and economical three-dimensional (3D) printed temporal bone model printed by a commercial desktop 3D printer, which can be widely promoted and applied in the training of beginners in otology.
Material And Methods: The CT data of the temporal bone were imported into Mimics to construct a 3D digital model of the temporal bone. After loaded into a high-precision 3D printer, a high-precision temporal bone model was printed at a scale of 1:1. Then, the model was evaluated by 5 senior attending physicians, including its morphological accuracy, simulation about surgery, advantages and educational value, using the 7-point Likert scale.
Results: A life-like temporal bone model was successfully printed out. Five senior attending physicians all thought that the printed model was similar to the natural temporal bone in physical properties and the haptic sensation of bone drilling, and was accurate, simple, convenient and effective. In addition, the model was considered to be of high application value in the teaching of temporal bone anatomy and surgery simulation, which had a material cost of only 3 dollars.
Conclusions: The high-precision 3D printed temporal bone model is highly similar to the natural temporal bone, and can be conveniently and effectively used in the training of simulating temporal bone surgery for beginners in otology. Its production is simple and economical, so it can be popularized on a large scale.

Breaking the Bone Marrow Barrier: Peripheral Blood as a Gateway to Measurable Residual Disease Detection in Acute Myelogenous Leukemia.

Acute myeloid leukemia (AML) is a genetically heterogeneous disease with high rates of relapse after initial treatment. Identifying measurable residual disease (MRD) following initial therapy is essential to assess response, predict patient outcomes, and identify those in need of additional intervention. Currently, MRD analysis relies on invasive, serial bone marrow (BM) biopsies, which complicate sample availability and processing time and negatively impact patient experience.

Background: This study aims to delineate the global, regional, and national burden of malignant neoplasms of bone and articular cartilage (MNBAC) among individuals aged 65 years and older from 1990 to 2021, stratified by age, sex, and sociodemographic index (SDI).
Methods: We harnessed data from the Global Burden of Disease Study 2021 to evaluate the prevalence, incidence, mortality, and disability-adjusted life years (DALYs) associated with MNBAC among individuals aged 65 years and older across 204 countries and territories between 1990 and 2021. The socio-demographic Index (SDI) served as a metric to examine the influence of socioeconomic development on the burden of MNBAC.
Analysis and characterization of interhypothalamic adhesions in adults: No longer only a pediatric finding.

Department of Radiology, Medical School, University of Minnesota, USA.
Background And Purpose: Inter-hypothalamic adhesions (IHAs) are parenchymal tissue bridges traversing the third ventricle, previously reported only in the pediatric population. We aim to understand the prevalence of IHA in the adult population, assess their size and location, and ultimately investigate whether IHA volumes correlate with age.
Materials And Methods: Patients who underwent routine high-resolution 3D T2WI MRI studies of the temporal bone/internal auditory canal at an otolaryngology clinic between 2008 and 2014 were consecutively selected.
