Erji Gao, Yang Li, Tiancheng Zhao, Xiang Guo, Weiwei He, Weiming Wu, Yonghong Zhao, Yi Yang
There are studies confirmed that for severe flail chest or sternal fractures, even multiple rib fractures, surgery can effectively reduce hospital stay and relieve chest wall pain. But it is a challenge to fix too many costal cartilage fractures in such a small area if we just put internal fixator directly on the sternum. Through this case report we want to share our method of fixation of multiple costal cartilage and sternal fractures at the same time through a small incision, and it is also appropriate for multiple costal cartilage fractures without sternal fracture...

The effect of intercostal muscle contraction on generating rib motion has been investigated for a long time and is still controversial in physiology. This may be because of the complicated structure of the rib cage, making direct prediction of the relationship between intercostal muscle force and rib movement impossible. Finite element analysis (FEA) is a useful tool, which is good at solving complex structural mechanic problems. In this study, we individually activated the intercostal muscle groups from the dorsal to ventral portions, and obtained five different rib motions classified based on rib moving directions...

Infrared (IR) laser impact has no analogues for rapid and safe cartilage reshaping. For better penetration of radiation optical clearing agents (OCAs) can be applied. In present work the effect of low-osmolality agent iohexol on costal cartilage is studied. Specifically, it is shown that ½ of total increase of optical transparency occurs in 20 min of immersion. Maximally, cartilage transparency on 1560 nm can be increased in 1.5 times. Injection of iohexol results in increased tissue hygroscopicity, lower drying rate and higher percentage of bound water...

Tip surgery during rhinoplasty is particularly difficult in Asians. Tip grafting is the best approach. Conchal cartilage with perichondrium and costal cartilage are powerful grafting materials. The most important grafting techniques are tip-onlay grafting, shield grafting, and multilayer tip grafting. Tip-onlay grafts are useful for dorsal convexity. Shield grafts require sufficient support to prevent bending. Multilayer tip grafts (usually 2 layers) are versatile. Asians vary in cartilage configuration, skin thickness, and aesthetic desires: tip-grafting strategies must be tailored to meet the aesthetic goals of individuals...

Autogenous materials used for Asian dorsal augmentation are temporal fascia, dermofat, solid block type of costal cartilage, and diced cartilage. The temporal fascia is used for radix augmentation or correction of minor focal depression. Dermofat, solid block costal cartilage, and diced cartilage are recommended for major dorsal augmentation. The vertically oriented folded dermal graft curtails use of the fat component. Diced cartilage wrapped in temporal fascia exhibits a lower resorption rate, and may easily fit into the contour of the dorsum...

Resection of sternal tumors can leave large defects, which exposes major mediastinal structures, and can affect respiratory mechanics. If feasible, resection is potentially a complex reconstructive challenge to restore normal and functional anatomy using conventional techniques. We report the first Australian use of a three-dimensional-printed titanium and PoreStar prosthesis in a 39-year-old woman for reconstruction after major surgical resection of the sternum for metastatic breast cancer. The patient successfully underwent excision of the sternum and costal cartilages as well as implantation of the prosthesis...

Background: Microtia reconstruction is a challenging procedure, especially in developing nations. The most complex part is learning how to fabricate a framework from costal cartilage. We herein propose a training regimen for ear reconstruction with the use of a plastic eraser. Materials and Methods: The texture of a plastic eraser made from polyvinyl chloride is similar to that of human costal cartilage. The first step of the training is carving out the sixth through eighth rib cartilages from a block of plastic eraser...

The goal of nasal reconstruction surgery is to restore normal nasal shape and function, and its success begins with creating a stable framework. In this article the authors discuss the most advantageous materials for building such a framework and how to design this element to achieve better and more durable outcomes. This is a retrospective study including patients who underwent nasal reconstruction in our rhinoplasty and nasal reconstruction center at a tertiary referral hospital between 2006 and 2016. Data included patient characteristics, defect location, the reason for defect, use of supporting structure, flap, lining, and complications were recorded...

BACKGROUND: Numerous modifications have been successfully applied in microtia reconstruction over the past several decades, and lobular transposition has become a routine technique in a two-stage operation. However, it is still a demanding challenge to manipulate the remnant ear with various quantities or positions in lobule-type microtia. The authors demonstrate the relevant details of treating remnant tissue in different conditions. METHODS: A total of 390 lobule-type microtia patients underwent autogenous costal cartilage auricular reconstruction between 2010 and 2015...

BACKGROUND: Reinforcement of lower lateral crura (LLC) is an imperative prophylaxis against the secondary deformity of alar and nasal tip in Asian rhinoplasty. The common limitation of the existing techniques is loss of nasal tip's mobility to a large degree in exchange for structural stability. In search for a natural and animated postoperative nasal tip, the elasticity and rigidity of coastal periphery was taken into account. METHOD: Two pieces of sliced costal periphery (SCP) were used to reinforce the LLC...

We report a case of atrial septal defect (ASD) with severe pectus excavatum. A 50-year-old female had a stroke due to paradoxical embolism from deep vein thrombosis thorough ASD. Her preoperative computed tomography(CT) revealed a severe pectus excavatum (Haller CT index 28.6). The patient underwent ASD closure and repair of the pectus excavatum concomitantly. Median full sternotomy was performed for ASD closure. And we adopted sterno-costal elevation for pectus excavatum repair. Cartilages of the 3rd to the 7th rib were segmentally resected and the remainders were re-sutured to the sternum...
