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...

OBJECTIVE: The involvement of the dura is a rare yet potentially life-threatening complication during cholesteatoma surgery. Thus, the knowledge about treatment and consequences of this issue is of great importance to every ear surgeon. METHODS: This retrospective study analyzed the dura involvement with regard to the type of defect, reconstruction method used, and the post-operative complications of 1291 pediatric and adult cholesteatoma surgeries performed at an academic tertiary care center over a twelve-year period...

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...

Vicki S Sharma, Robert E Stephens, Barth W Wright, Christopher C Surek
BACKGROUND: Current literature suggests that preserving the lobular branch of the great auricular nerve has greater impact on sensory function of the auricle than preservation of the posterior branch during rhytidectomy. However, no methodology exists to efficiently and accurately determine the topographic location of the lobular branch. This study describes the branching characteristics of the lobular branch and algorithmic surface markings to assist surgeons in preservation of the great auricular nerve during rhytidectomy flap elevation...

Yong Ju Jang, Do-Youn Kim
Revision rhinoplasty in Asian patients is associated with problems related to the use of grafts or implant materials. Moreover, the septal cartilage of Asian individuals is generally weak and small, which makes it particularly vulnerable to injury or secondary deformity during primary surgery. Hence, there is an increased demand for major reconstruction of the septal cartilage framework during revision surgery in Asian patients. In revision rhinoplasty of the nose in Asian patients, appropriate management of the graft or implant is vital...

BACKGROUND: Over the past few years, conchal cartilage has been most often used in rhinoplasty. The donor site complications following conchal cartilage graft harvesting are scar formation, hematoma formation, and delayed wound healing, although hematoma is one of the most important and common complications. A complete conchal defect as a complication of auricular cartilage graft harvesting has not been previously reported in the literature. The authors report an unusual case of an iatrogenic conchal defect resulting from conchal cartilage graft harvesting that was treated using a posterior auricular island flap...

Lying ears are defined as ears that protrude less from the head, and in frontal view, are characterized by lateral positioning of antihelical contour relative to the helical rim. These aesthetically displeasing ears require correction in accord with the goals of otoplasty stated by McDowell. The authors present a case of lying ears treated by correcting the conchomastoid angle using Z-plasty, resection of posterior auricular muscle, and correction of the conchoscaphal angle by releasing cartilage using 2 full-thickness incisions and grafting of a conchal cartilage spacer...
