Microtia is a congenital malformation affecting one in 5000 individuals and is characterized by physical deformity or absence of the outer ear. Nowadays, surgical reconstruction with autologous tissue is the most common clinical practice. The procedure requires a high level of manual and artistic techniques of a surgeon in carving and sculpting of harvested costal cartilage of the patient to recreate an auricular framework to insert within a skin pocket obtained at the malformed ear region. The aesthetic outcomes of the surgery are highly dependent on the experience of the surgeon performing the surgery...

Surface anatomy is considered a fundamental part of anatomy curricula and clinical practice. Recent studies have reappraised surface anatomy using CT, but the adolescent age group has yet to be appraised. Sixty adolescent thoracoabdominal CT scans (aged 12-18 years) were examined. The surface anatomy of the central veins, cardiac apex, diaphragmatic openings and structures in relation to the sternal angle plane were analyzed. The results showed that the brachiocephalic vein (left & right) formed mostly posterior to the sternoclavicular joint...

BACKGROUND:  Left pulmonary artery (LPA) sling (PAS) is a vascular ring, which is frequently associated with long-segment tracheal stenosis (TS). Mortality rate in operated children is still high, especially in cases of severe tracheal hypoplasia and/or associated congenital heart defects (CHDs). We report our experience of treatment and follow-up in a pediatric cohort of patients affected by PAS with severe tracheobronchial involvement. METHODS:  From 2005 to 2017, we enrolled 11 children diagnosed with PAS and congenital TS requiring surgical intervention...

In functional septorhinoplasty (FSRP), alternative grafting material is used if septal cartilage is insufficient for reconstructive needs. Autologous costal cartilage (ACC) and irradiated homologous costal cartilage (IHCC) are compared via the Nasal Obstruction Symptom Evaluation (NOSE) scale. One-hundred forty-one patients who underwent FSRP with ACC or IHCC between January 2013 and March 2018 were administered the NOSE scale pre- and postoperatively at 2, 4, 6, and 12 months. There was no significant difference in mean NOSE scores between the ACC and IHCC cohorts at the preoperative visit (68...

BACKGROUND: Pectus excavatum is a common chest wall deformity with no known cause. A common hypothesis is that in patients with pectus excavatum, there is an overgrowth of costal cartilage relative to healthy individuals. MATERIALS AND METHODS: We obtained radiological curvilinear three-dimensional measurements of the fourth to eighth costal cartilage and associated ribs in 16 patients with pectus excavatum and 16 age- and gender-matched controls between the ages of 6 and 32 y...

Infection of costal cartilage is a rare observation. We report the case of a 43-year-old male patient without relevant history who presented with a progressive painful swelling of the left chest wall since 4 months. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated an abscess within the left ninth costal cartilage with surrounding reactive changes. A CT-guided biopsy was performed and the culture of the sample revealed the presence of Prevotella nigrescens. Musculoskeletal infections by Prevotella are rarely described in the literature, Prevotella oralis and Prevotella bivia being the most frequently observed pathogens...

During the manufacture of cell- and tissue-based products, such as engineered cartilage for autologous chondrocyte implantation, maximizing the number of cells isolated from donor tissue substantially improves the productivity of these products. The method used for agitating tissues with digestive fluid and enzymes can considerably affect both the quality and quantity of isolated cells. This study aimed to investigate the effectiveness of a rotation/revolution-type agitator for chondrocyte isolation following the enzymatic digestion of rat costal cartilage...

A chondrosarcoma is a rare bone tumour derived from cartilage-producing malignant mesenchymal cells. A 25- year-old male patient was operated upon to treat a chondrosarcoma arising in the left 2nd and 6th ribs. The tumour underwent en bloc wide resection in collaboration with a plastic surgeon for reconstruction of the resected area. Costal chondrasarcoma is very rare but chondrosarcoma arising from two ribs at the same time has not been reported before in the literature.

BACKGROUND: Stability is essential for the normal healing of a sternotomy. Mechanical vibration transmittance may provide a new means of early detection of diastasis in the sternotomy and thus enable the prevention of further complications. We sought to confirm that vibration transmittance detects sternal diastasis in human tissue. METHODS: Ten adult human cadavers (8 males and 2 females) were used for sternal assessments with a device constructed in-house to measure the transmittance of a vibration stimulus across the median sternotomy at the second, third, and fourth costal cartilage...

We describe a case of 1-stage surgery comprising aortic valve replacement and thoracoplasty that was performed on an elderly patient with a good result. An 85 -year-old man visited our hospital with the chief complaint of chest discomfort. Examination revealed aortic regurgitation and pectus excavatum. Respiratory dysfunction, pulmonary hypertension, and cardiac failure were observed. We considered that pectus excavatum could affect breathing and circulation after surgery;therefore, we decided to perform a 1-stage surgery comprising aortic valve replacement and thoracoplasty...

Although surgical techniques for rhinoplasty and nasal reconstruction are well established, prospective research on postoperative morbidity remains limited. The aim of this pilot study was to assess costal and auricular cartilage donor site pain and morbidity in patients undergoing rhinoplasty and nasal reconstruction. In this prospective cohort study, we enrolled 55 patients undergoing nasal surgery that required costal or auricular cartilage harvest from February 2015 through May 2016. Each patient was given a symptom-specific patient survey that assessed general pain, nasal pain, graft donor site pain, graft donor site itching, color variation, skin stiffness and thickness, and graft donor site appearance at 1, 4, and 12 weeks after surgery...

A 61-year-old woman who lost her nose, upper lip, and most of her midface bony structures because of cancer 20 years previously underwent advanced surgical reconstruction. This patient previously underwent multiple reconstructive surgeries that failed to satisfactorily restore her nose. Therefore, a multistage reconstruction was performed to recreate a complete nose and increase her upper lip length. Because of a lack of sufficient facial bone and nasal supporting structures, the reconstruction was extremely challenging...

Background: In revision rhinoplasty, insufficient septal cartilage is a common finding. In these cases, harvesting of costal cartilage or conchal cartilage is needed which is time consuming and has morbidity. Use of the septal bone/cartilage composite graft or bony-cartilaginous unit as a graft in rhinoplasty is a new technique. Objectives: The aim of this research was to evaluate subjective and objective effects of using this graft in revision rhinoplasty. Methods: In this clinical trial study, we examined 40 patients lacking sufficient septal cartilage for grafting who referred to a tertiary center and a private setting from January 2016 to March 2017 for revision septorhinoplasty...

Slipping rib syndrome is an often unrecognized and underdiagnosed condition caused by the increased mobility of the anterior ends of the costal cartilages of the false ribs. Patients usually present with severe intermittent abdominal pain that is exacerbated by various physical movements. Diagnosis of slipping rib syndrome is mainly clinical and can be confirmed by a physical examination technique termed the "Hooking Maneuver." Treatment includes conservative therapy, intercostal nerve block and surgical operation...

Costal cartilage is much understudied compared to the load bearing cartilages. Abnormally grown costal cartilages are associated with the inherited chest wall deformities pectus excavatum and pectus carinatum resulting in sunken or pigeon chest respectively. A lack of understanding of the ultrastructural and molecular biology properties of costal cartilage is a major confounder in predicting causes and outcomes of these disorders. Due to the avascular nature of cartilage, chondrocytes metabolize glycolytically, producing an acidic environment...

Augmentation rhinoplasty is commonly performed to raise the nasal dorsum in Asian individuals. However, materials used for dorsal augmentation are associated with various surgical challenges and complications. In this article, the authors present a novel dorsal augmentation technique combining hybrid autologous costal grafts with septal extension grafts. The records of 28 patients (19 women and 9 men; mean age: 27 years; range: 18-43 years) who underwent augmentation rhinoplasty (primary or revision) with our novel technique from December 2007 to December 2016 were retrospectively reviewed...

AIM OF THE STUDY: The slipping rib syndrome (SRS) is an unknown pathology for the pediatric surgeon due to its low incidence in children. The weakness of the costal ligaments allowing an area of rib hypermobility has been postulated recently as the main etiology. It produces an intermittent pain in the lower thorax or upper abdomen that can affect to the daily activities and can be the origin of unspecific chronic pain. METHODS: A retrospective review of patients diagnosed with SRS between october 2012 and march 2017 was performed...
