REVIEW
Akira Yamada
Nagata technique becomes most popular method of autologous rib microtia construction. To achieve successful outcome, 3 keys must be perfect: skin envelope, 3D cartilage framework, and proper location of the construct. The first step of the surgery is to identify "auricular rectangle." Relationship between the auricular rectangle and the vestige will determine if the vestige is usable for surgery. Rib cartilage must be harvested without perichondrium to prevent chest deformity. Lobule split technique is the hallmark of the Nagata technique, which allows skin envelope expansion, and allows deeper conchal cavity...

BACKGROUND: Mechanical properties of tissue-engineered cartilage and a variety of endogenous cartilage were measured. The main goal was to evaluate if the tissue-engineered cartilage have similar mechanical characteristics to be replaced with rib cartilage in microtia reconstruction. Such study lays the foundation for future human clinical trials for microtia reconstruction. METHOD: Atomic force microscopy and compression testing were used to measure the viscoelasticity of tissue-engineered cartilage (stem cell seeded on Poly lactic co-glycolytic acid nanofibers and Pellet) and endogenous cartilage: conchal bowl, microtic ears, preauricular remnants, and rib...

BACKGROUND: Septal extension graft is currently the most commonly used primary and secondary rhinoplasty technique in Asia because it provides maximal tip projection and rotational controllability. We designed this study to compare the tip projection amount and rotational controllability of the tip support between the septal extension graft based on the L-strut septum and double-layered conchal cartilage graft based on the full septum at the nasal tip. METHOD: A total 27 consecutive patients who underwent nasal tip plasty with the septal extension graft or double-layered conchal cartilage graft for purely esthetic reasons between March 2014 and July 2016...

Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet. Autogenous grafts and alloplastic and allogenic materials with a wide variety of advantages and disadvantages have been discussed...

Nasal augmentation is a popular modern technique requested by many Asian people.There are two kinds of autologous cartilage used to augment the nose at present: carved as a monobloc or diced into pieces. Each approach has its pros and cons.We performed our surgical technique on a group of 28 patients. Twenty of these patients had had several rhinoplasties performed before referral to our hospital; 8 of these patients had undergone a primary rhinoplasty. bilateral conchal, nasal septum, or rib cartilage were harvested, deep temporal fascia or abdominal muscle fascia to be prepared for packing stripped cartilage were also removed at this time...

PURPOSE: To evaluate the use of cartilage as a potential graft material toward osteo-odontal tissue replacement in keratoprosthesis surgery. METHODS: We describe a modification of the osteo-odonto-keratoprosthesis surgery that involves the use of autologous auricular conchal cartilage graft (ACCG). In stage 1a, a full-thickness cheek mucosa graft was performed over the ocular surface. In stage 1b, ACCG was harvested via a retroauricular approach. An optical polymethyl-methacrylate cylinder was embedded into a double-layered fragment of cartilage and secured by cyanoacrylate glue...

The nose forms the first 8 cm of the upper respiratory tract and is responsible for cleansing, humidification, and temperature control of the supplied air. This is also referred to as conditioning. The nasal valve region, formed by the head of the lower nasal concha, portions of the cartilaginous septum, and the upper lateral cartilage, is responsible for diffusing and accelerating the respiratory airflow. Prerequisite are regular mucociliary clearance and sufficient air passage. Hypertrophy of the lower nasal turbinate is one of the most common causes of symptomatic nasal congestion...

The goal of auricular cartilage harvest is to obtain a sufficient amount for reconstruction and to minimize the change in ear shape. The cartilage can be harvested by a posterior or anterior approach, and each method has advantages and disadvantages. The posterior approach presents the advantage of scar concealment, but there are limits to the amount of cymba cartilage that may be harvested. In contrast, the anterior approach may cause a noticeable scar. However, as cartilage is collected, the anterior approach provides a view that facilitates the preservation ear structure...

BACKGROUND: Previous regeneration studies of auricle-shaped cartilage by tissue engineering leave unresolved whether the chondrocyte phenotype from human auricular chondrocytes seeded onto polymeric scaffolds is retained over the long term and whether microtia remnants may be a viable cell source for auricular reconstruction. METHODS: Chondrocytes were isolated from human ears, either normal conchal ear or microtia cartilage remnants, expanded in vitro, and seeded onto nanoscale-diameter polyglycolic acid sheets...

BACKGROUND: Secondary rhinoplasty often involves the addition of autogenous graft material to add volume, structure, support and to camouflage cartilage and bone grafts. A variety of fascias have been used to camouflage, wrap and give "fill" in secondary rhinoplasty. The posterior auricular fascia is a source of material ideal for such purposes, and its quantity, anatomical structure and ease of harvest with minimal donor site morbidity make it a versatile and attractive autogenous graft...

BACKGROUND: Regarding septal fixation in nasal tip plasty, the nasal tip tripod theory may require modification. We performed three-dimensional (3D) photogrammetric analysis of the "Skiff graft," which is a quadripod method involving folded conchal cartilages fixated on the caudal septal angle, paired lateral crura reinforced by a derotational conchal cartilage graft, and conjoined medial crus on the columella base. We assessed the efficacy of the Skiff graft in maintaining tip projection and preventing cephalic rotation of the nasal tip...
