Background: Reconstruction of the cephaloauricular sulcus in patients with microtia in ear reconstructions remains challenging. Costal cartilage and other support materials wedge were used for ear elevation. Each material has its disadvantages. To reconstruct a stable cephaloauricular sulcus and reduce costal cartilage harvesting, we used two titanium plate struts to support the costal cartilage framework.
Methods: A titanium plate strut was designed. The angle of the strut was 60°, the arm length was 0.8 cm, and the width was 0.5 cm. The thickness was 0.6 mm. Four small pores are formed on the titanium plate. The implanted framework was separated from the underlying bed. Two titanium plate struts were fixed on the raised ear framework, tendon, and periosteum, and then wrapped with a turned-over retroauricular fascia flap. The raw surface was covered with a split-thickness skin graft, harvested from the scalp.
Results: From 2019 to 2022, 51 patients underwent second-stage operations. All patients were followed up for a minimum of 6 months. The auricular projection was well-maintained, and the cephaloauricular sulcus of the constructed auricle was acceptable in 50 patients. There was one infection, and the titanium plate struts were removed, which resulted in shrinking cephaloauricular angles.
Conclusions: Titanium plate is effective as a supportive material to obtain the proper and firm projection of the constructed auricle. It provides a new option for patients whose costal cartilage volume is insufficient or who do not want to have the costal cartilage harvested again.

In this present investigation, plant-mediated synthesis of titanium oxide (TiO) nanoparticles was synthesized from seagrass (Thalassia hemprichi) using the hot plate combustion method (HPCM). Synthesized TiO nanoparticles optical, functional, structural, and morphology properties were analyzed by UV-visible spectroscopy, Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). SEM analysis confirmed the spherical shape of the TiO nanoparticles were observed in various sizes, viz.

In cases of large mandibular continuity defects resulting from malignancy resection, the current standard of care involves using patient-specific/custom titanium reconstruction plates along with autogenous grafts (fibula, scapula, or iliac crest segments). However, when grafts are not feasible or desired, only the reconstruction plate is used to bridge the gap. Unfortunately, metal osteosynthesis and reconstruction plates, including titanium, exhibit adverse effects such as stress-shielding and limitations in accurate postoperative irradiation (especially with proton-beam therapy).

Article Synopsis
- Using alternating currents (AC) can effectively prevent the formation of mineral crystals on surfaces in contact with super-saturated fluids, such as heat exchangers and pipes.
- The study demonstrates that periodic charging and discharging of the electrical double layer (EDL) on titanium sheets in super-saturated CaCO solutions inhibits both crystal nucleation and growth due to enhanced ion migration.
- Operating at 4 V and frequencies between 0.1-10 Hz results in over 96% reduction in turbidity and over 92% reduction in calcium carbonate coverage, showcasing a promising method for controlling mineral scaling in various industrial applications.

The state-of-the-art approach to open reduction and fixation (ORIF) of zygoma fracture fragments is based on manual skills. Achieving high accuracy can be challenging. Our feasibility study on deceased body donors with artificial zygomatic fractures investigated whether virtual repositioning of the fractures and the use of customised 3D-printed titanium osteosynthesis plates was similar in accuracy to the conventional manual procedure, and whether the method was applicable in a clinical setting.

Background: Costal cartilage injuries are unappreciated, and there is a paucity of reports on fixation methods. This study aims to evaluate the safety of titanium plate internal fixation for costal cartilage injuries.
Methods: A retrospective analysis was conducted on 30 patients with costal cartilage injuries who underwent titanium plate internal fixation between April 2016 and November 2022 at our hospital.
