AI Article Synopsis
- The study focuses on creating a three-dimensional framework using autogenous cartilage for ear reconstruction in patients with microtia.
- The fabrication process involves harvesting rib cartilage, carving it into specific parts of the ear structure, and assembling these pieces to match the ear's natural contour.
- Over 14 years, the method was successfully applied to over 5,200 patients, resulting in naturally-looking, well-contoured reconstructed ears.
Article Abstract
Objective: To explore the fabrication and application of three-dimensional autogenous cartilage framework in auricular reconstruction.
Methods: The process of fabrication of three-dimensional cartilage framework consisted of cartilage harvesting, carving and assembling the cartilage. The rib cartilage was harvested separately. The three-dimensional framework was composed of three main parts:the helix, the base and the pad, at different layer. The framework was fabricated according to the development of rib cartilage and contour and height of the reconstructed ear.
Results: From January 1992 to December 2006, 5,248 patients of microtia were treated with 6,252 autogenous cartilage frameworks.
Conclusions: The three-dimensional framework is easily manipulated. The reconstructed ears look natural and had an erect contour. This method can effectively use the cartilage.

Objective: Bilateral cleft lip nose deformity often involves nasal alar retraction. The use of autogenous auricular cartilage for correction further aggravated nasal alar retraction caused by nasal lining defects after the operation. A novel graft was developed to address bilateral cleft lip nose deformity.

Article Synopsis
- - A patient with a left ear deformity from a flame burn received a 3-stage reconstruction using an expanded neck flap and rib cartilage as the framework for the ear.
- - The reconstruction involved implanting tissue expanders, excising scar tissue, and using the expanded flap to cover the ear framework, followed by final shaping and scar removal.
- - After one year, the reconstruction healed well with minor complications, resulting in a realistic ear shape and improved appearance, suggesting that expanded neck flaps can be an effective solution for burn patients with limited flap options.

The surgical reconstruction of severe corneal ulcers is a common and crucial component of the clinical practice of veterinary ophthalmology. Numerous surgical techniques are used in dogs for corneal reconstruction, and these techniques may be categorized by the material used to repair the corneal lesion. The first part of the present review described procedures that utilize autogenous ocular tissues, homologous donor tissues, and heterologous donor tissues.

Article Synopsis
- * Common techniques include the use of autospreader flaps and spreader grafts.
- * Surgeons can often utilize various types of cartilage (septal, auricular, and costal) for grafting, favoring the use of the patient's own tissues.

Objective: To observe the effects of electroacupuncture (EA) at "Jiaji" (EX-B 2) on extracellular matrix (ECM) of chondrocytes and inflammatory reaction in rabbits with Modic changes (MC) of cartilage endplate, and to explore the mechanism of EA in treating MC of endplate cartilage.
Methods: Eighteen male New Zealand white rabbits were randomly divided into a sham operation group, a model group and an EA group, 6 rabbits in each group. Based on the autoimmune theory, MC model was established by embedding autogenous nucleus pulposus in the rabbits of the model group and the EA group, based on autoimmunity.
