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...

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...

A 52-year-old woman sustained a fracture of the left 7th costal cartilage after a ski injury. She presented complaining of painful clicking over the area. Initial imaging studies were negative for fracture; however, 3-D reconstruction of a chest CT, formatted to costal cartilage, revealed the fracture. She was offered and underwent surgical fixation of the fracture with a plate and four screws using a bi-axial, convergent construct. Postoperatively, her symptoms resolved. In this case report, we review the rationale for fixation of costal cartilage, including a summary of previous literature pertaining to this relatively rare thoracic injury...

Tietze's syndrome is a benign, self-limiting arthropathy, without purulent character. The disease most often involves articulations: sternocostal, sternoclavicular, or costochondral joints. The characteristic symptoms are tenderness, pain and edema involving one of the aforementioned joints on one side. Diagnosis of Tietze's syndrome is based on physical examination (increase of palpation tenderness in the affected joint), laboratory tests (increase of inflammatory parameters) and imaging studies (USG, MRI)...

Wegener granulomatosis (WG) is a necrotizing vasculitis that involves the upper respiratory tract, the lungs, and the kidneys. It also causes deformities of the nose in practically all patients, altering the cartilaginous and bony structure as well as the inner lining of the nose.The surgical repair of these nasal distortions is a challenge mainly due to the impairment of wound healing and graft take that is caused both by the disease itself and by the prolonged immunosuppressant treatment.Many different reconstruction plans have been developed, using costal or calvarial bone grafts, cartilage grafts and local skin and mucosa flaps...

The involvement of the respiratory muscular pump makes SMA children prone to frequent hospitalization and morbidity, particularly in type 1. Progressive weakness affects ribcage muscles resulting in bell-shaped chest that was never quantified. The aims of the present work were: (1) to quantify the presence of bell-shaped chest in SMA infants and children and to correlate it with the action of ribcage muscles, assessed by the contribution of pulmonary ribcage to tidal volume (ΔVRC, p ); (2) to verify if and how the structure of the ribcage and ΔVRC, p change after 1-year in SMA type 2...

The Nuss procedure is the most minimally invasive and commonly used surgical correction for pectus excavatum (PE) by using a prebent pectus bar to elevate the deformed chest wall. However, there are some complications associated with this procedure such as postoperative pain as well as surgical uncertainties because of human judgment. It is therefore important to understand the biomechanical effect of the pectus bar on PE thoraces undergoing an operation to alleviate the postoperative pain as well as to improve surgical outcome...

Robert Edward Kelly
The procedure introduced by Donald Nuss in 1997 for the treatment of pectus excavatum at the American Pediatric Surgical Association meeting has now been adopted by pediatric, thoracic, and plastic surgeons around the world. Rather than resection of the costal cartilages and sternal fracture, which had been standard practice for decades, he advocated using a metal bar to push the sternum into position. Reasoning that the chest wall of children is very flexible, he felt that resection was unnecessary. Since that time, medical centers from around the world have reported their experience with the procedure...
