OBJECTIVE To define the modulus of elasticity for nasal septum, auricular, upper lateral, and lower lateral cartilages. METHODS Prospective enrollment of sequential patients undergoing septorhinoplasty. Test samples were obtained through routine surgical interventions using atraumatic harvesting techniques. The modulus of elasticity was determined using a customized biomechanical testing devi...

Ungual cartilage ossification in the forelimb is a common finding in horses. Subtle abnormalities associated with the ungual cartilages can be difficult to identify on radiographs. Magnetic resonance (MR) imaging findings of 22 horses (23 forelimbs) with a fracture of the distal phalanx and ossified ungual cartilage were characterized and graded. All horses had a forelimb fracture. Eleven invol...

Most repair of heart lesions and pectus deformity has been performed in adult patients using long incisions, sternal splits, excision of deformed cartilages, and sternal turnover operations that could result in poor cosmesis and chest growth in children because of sternal devascularization. We performed simultaneous pectus repair and atrial septal defect closure in 2 children using a short long...

Background: Microtia is a congenital abnormality of the auricle. One important comprehensive management microtia ear reconstruction. Reconstruction using an auricle framework from autologous material originating rib cartilages still gold standard. However, currently, some surgeons prefer alloplastic materials which are claimed to reduce morbidity and can be performed at younger age. Objective: ...

The aim of this paper is to report the management and the outcomes in 67 patients admitted for suspected ingestion of foreign body between December 2012 and December 2014. METHODS This retrospective study was conducted at Palermo University Hospitals, Italy, over a 2...

Vocal folds are used as sound sources in various species, but it is unknown how vocal fold morphologies are optimized for different acoustic objectives. Here we identify two main variables affecting range of vocal fold vibration frequency, namely vocal fold elongation and tissue fiber stress. A simple vibrating string model is used to predict fundamental frequency ranges across species of diffe...

Study Design: A review of all the cases of thyroid cartilage chondrosarcoma reported in the literature up to January 2013. Methods: The search was carried out through the introduction of the MeSH terms: Chondr...
