Conchal cartilage

Man Koon Suh, Seung Jong Lee, Yeon-Jun Kim
BACKGROUND: Nasal septal cartilage and conchal cartilages are preferred sources of grafts in augmentation rhinoplasty. Rib cartilage can also be used, but it may evoke a patient's concerns about a scar and an extensive surgery. In such cases, irradiated homologous costal cartilage (IHCC) can be a useful alternative. However, controversy still exists in many literatures regarding complications with use of IHCC. Therefore, the authors reviewed our experiences with IHCC in rhinoplasty and analyzed the complications in relation to graft location...

BACKGROUND: Cleft lip and palate are the most common craniofacial congenital malformations. Timing of the nasal repair remains somewhat controversial. Some authors perform a combined nasal and lip repair in infancy while others advocate for a staged repair with the nasal component occurring later in childhood. Frequently, secondary repair is needed to address residual nasal deformities in early adulthood. Conchal cartilage has become increasingly popular as a source of cartilage for secondary reconstruction...

BACKGROUND: Nasal reconstruction after burn injury can be challenging due to limited availability of local flaps. We present our experience of free flap reconstruction for full-thickness nasal defect after severe facial burn injury. METHODS: Between August 1998 and September 2015, six patients underwent nasal reconstruction with seven free flaps after burn injury. Among them, flame burn occurred in two patients, chemical burn in two, explosive burn in one, and contact thermal burn in one patient...

BACKGROUND: Floppy eyelid syndrome (FES) is typically characterized by chronic eye irritation and an increased laxity of the upper eyelid that can be easily everted by applying minimal upward traction. However, it is a clinical entity that is less known to most plastic surgeons. Blepharoptosis is one of the most common features, which links to FES, for which a thorough differential diagnosis has become important in directing proper medical treatment. PURPOSE: This review aims to discuss current understanding about FES in a broader spectrum, encompassing the clinical features and evaluation of FES, the underlying etiologies, systemic associations, and surgical procedures for upper eyelid tightening...

Advances in aesthetic rhinoplasty using conchal cartilage grafts have led to a high occurrence of retroauricular keloids. The purpose of this study is to introduce our surgical experiences using a keystone flap in retroauricular keloids following conchal cartilage grafts. The present study is a retrospective review of patients with pathologically confirmed retroauricular keloids following conchal cartilage grafts. These cases were surgically excised and we covered the defect with a keystone flap followed by one-time steroid injection at postoperative day 14 and silicone gel sheeting application for 3 months...

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...

We conducted an experiment to investigate the effectiveness of bacterial cellulose, a new graft material, in correcting and preventing dorsal nasal disorder in rhinoplasty. The experiment was performed on 20 Wistar albino rats. The rats were evenly divided into two groups: a fascia group and a cellulose group. In the fascia group, grafts from the conchal cartilage were removed, shredded, and then wrapped in temporal muscle fascia. In the cellulose group, shredded cartilage was wrapped in the bacterial cellulose...

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. The authors performed their surgical technique on a group of 28 patients. Twenty of these patients had undergone rhinoplasties performed before referral to our hospital; eight of these patients had undergone a primary rhinoplasty. Bilateral conchal, nasal septum, or rib cartilage was harvested; deep temporal fascia or abdominal muscle fascia to be prepared for packing stripped cartilage was also removed at this time...
