Purpose: Patients affected by severe atresia auris (AA) can be a challenge during hearing restoration surgery due to the abnormal position of vascular and nervous structures in the bone. A 3D reconstruction model of malformed temporal bones can be helpful for planning surgery and optimizing intra-, peri-, and post-operative results.
Method: A 5-year-old girl with severe AA on the right side was implanted with a Bonebridge transcutaneous bone conduction implant (tBCI). 3D printing was used to reproduce the malformed temporal bone, find a good position for the tBCI and plan out the surgical details in advance. Hearing tests were performed before and after surgery and information about intra-, peri-, and post-operative outcomes were collected.
Results: The patient did not show any negative outcomes and, thanks to the Bonebridge, completely recovered hearing on the right side.
Conclusions: 3D printing is a useful tool for planning surgery in AA patients and for preventing possible risks related to the unknown malformed anatomy.

Purpose: To evaluate the identification of nasal bone fractures and their clinical diagnostic significance for three-dimensional (3D) reconstruction of maxillofacial computed tomography (CT) images by applying artificial intelligence (AI) with deep learning (DL).
Methods: CT maxillofacial 3D reconstruction images of 39 patients with normal nasal bone and 43 patients with nasal bone fracture were retrospectively analysed, and a total of 247 images were obtained in three directions: the orthostatic, left lateral and right lateral positions. The CT scan images of all patients were reviewed by two senior specialists to confirm the presence or absence of nasal fractures.

Injury caused by excess reactive oxygen species (ROS) may lead to susceptibility to bacterial infection and sustained inflammatory response, which are the major factors impeding diabetic wound healing. By utilizing optimal anti-inflammatory, antioxidant and antibacterial biomaterials for multifunctional wound dressings is critical in clinical applications. In this study, a novel electrospun PLGA/MoS@Pd nanofiber membrane was synthesized by encapsulating antioxidant and near-infrared (NIR) responsive MOS@Pd nanozymes in PLGA nanofibers to form a multifunctional dressing for diabetic wound repair.

Improving and expanding ground-based field methods for measuring the above-ground biomass (AGB) may enable more sample collections across a landscape and over succession regimes and better harmonize with other remote sensing techniques. Developments and increased adoption of unoccupied aerial systems (UAS) and instrumentation for vegetation monitoring enable greater understanding of vegetation in many ecosystems.

Mechanisms driving the spatial and temporal patterns of species distribution in the Earth's largest habitat, the deep ocean, remain largely enigmatic. The late Miocene to the Pliocene (~23-2.58 Ma) is a period that was marked by significant geological, climatic, and oceanographic changes.

Background: Current management of patients with borderline resectable pancreatic adenocarcinoma (BR-PDAC) depends on the degree of involvement of the major arterial and venous structures. The aim of this study was to evaluate 3D segmentation and printing to predict tumor size and vascular involvement of BR-PDAC to improve pre-operative planning of vascular resection and better select patients for neoadjuvant therapy.
Methods: We retrospectively evaluated 16 patients with BR-PDAC near vascular structures who underwent pancreatoduodenectomy (PD) with or without vascular resection between 2015 and 2021.
