Usefulness of customized titanium plates for midface contouring surgery.

Introduction And Importance: In our department, we have been performing bone reconstructions on a case-by-case basis using vascularized free tissue transfers and custom-made artificial bones (HA). While these procedures have specific advantages, they are also limited in terms of the invasiveness as well as the stability and strength of implants. In the present study, we describe the use of a CTP to achieve minimally invasive midface plastic surgery with the superior moldability of a 3D structure and reliable stability compared to the use of autologous tissue.

Influence of Periosteum Location on the Bone and Cartilage in Tissue-Engineered Phalanx.

Purpose: This study investigated the influence of periosteal tissue of different origins on the calcification at the diaphysis and chondrocyte maturation at the epiphysis in an engineered phalanx. We hypothesized that the periosteum from long bones would better provide donor cells for bone formation and signals for maturation of the joint cartilage.

Methods: Periosteum was harvested from 4 locations (cranium, mandible, radius, and ilium) of calf bones.

Involvement of inward upper eyelid push on the lower eyelid during eyelid closure in development of involutional lower eyelid entropion.

Purpose: To examine whether an inward upper eyelid push on the lower eyelid margin during eyelid closure is involved in involutional lower eyelid entropion.

Methods: This prospective observational study included 34 sides from 27 patients with involutional lower eyelid entropion. The positional relationship between the upper and the affected lower eyelid margins during eyelid closure were examined before and after posterior layer advancement of the lower eyelid retractors.

Image analysis of the inferior rectus muscle in orbital floor fracture using cine mode magnetic resonance imaging.

Purpose: The main cause of diplopia induced by orbital floor fracture is strangulation or damage of the extraocular muscles, and the outcome varies depending on the severity of trauma. In this study, we evaluated the dynamics of the eyeball and inferior rectus muscle based on cine magnetic resonance (MR) images acquired before surgery. The preoperative images and outcomes were retrospectively investigated.
