Justin D Sawyer, Morgan L Wilson, Michael W Neumeister
Background: Historically, external ear melanomas have been treated aggressively, due to early perceptions suggesting they had poor prognosis and aggressive biological behavior. More recent evidence has not supported these notions. Methods: We completed a complete review of the literature involving malignant melanoma of the external ear. We then completed a quantitative analysis on seventy-three cases from 8 reports that contained case-level data, assessing factors that influence recurrence, and assessing characteristics of the melanomas based on histological subtype...

Objective: To explore the application and effectiveness of thin-ribbed cartilage with the perichondrium in the correction of secondary cleft lip nasal deformity as the lateral crural onlay graft. Methods: A retrospective study was performed based on the data of 28 patients with secondary nasal deformity of cleft lip between October 2015 and April 2017. There were 16 males and 12 females with an average age of 24 years (range, 18-31 years). There were 11 cases with secondary nasal deformities on the left side, 13 cases on the right side, and 4 cases on both sides...

Objective: To investigate the efficacy of the application of tragus cartilage-perichondrium in open method tympanoplasty. Method: Thirty patients with middle ear cholesteatoma were treated with open method tympanoplasty and titanium ossicular prosthesis replacement surgery utilized the tragus cartilage-perichondrium, the air-bone gap and the recovery of tympanic membrane were observed before and after operation. Result: Thirty ears achieved primary healing. After a follow-up of 12 months, no prosthesis extrusion and atticus lateral wall collapse were observed...

OBJECTIVE: The aim of this study was to evaluate and compare myringoplasty results from two different consecutive series conducted at the Kuopio University Hospital during a four-decade period. MATERIALS AND METHODS: We reviewed 315 patients (a total of 338 ears) who underwent myringoplasty at Kuopio University Hospital between the years 1986 and 2012. The results from this series were compared with those form a previously published series of 404 patients who underwent myringoplasty between 1970 and 1985 at the same institution...

Hereditary multiple exostoses (HME) is a pediatric disorder caused by heparan sulfate (HS) deficiency and is characterized by growth plate-associated osteochondromas. Previously, we found that osteochondroma formation in mouse models is preceded by ectopic bone morphogenetic protein (BMP) signaling in the perichondrium, but the mechanistic relationships between BMP signaling and HS deficiency remain unclear. Therefore, we used an HS antagonist (surfen) to investigate the effects of this HS interference on BMP signaling, ligand availability, cell-surface BMP receptor (BMPR) dynamics, and BMPR interactions in Ad-293 and C3H/10T1/2 cells...

PURPOSE: The significant shortcomings associated with current autologous reconstructive options for auricular deformities have inspired great interest in a tissue engineering solution. A major obstacle in the engineering of human auricular cartilage is the availability of sufficient autologous human chondrocytes. A clinically obtainable amount of auricular cartilage tissue (ie, 1 g) only yields approximately 10 million cells, where 25 times this amount is needed for the fabrication of a full-scale pediatric ear...

OBJECTIVE: This study reviewed available literature to evaluate the success rate of fat myringoplasty compared with methods using other graft materials and suggests proper indications for this procedure. DATA SOURCES: Studies reporting the success rate of fat myringoplasty were systematically reviewed by searching the MEDLINE, PubMed, and Embase databases for studies published from database inception to 2017. STUDY SELECTION: The following terms were used for the literature search: ("Fat" OR "Adipose") and ("Myringoplasty" OR "Tympanoplasty")...

Septoclasts are mononuclear spindle-shaped phagocytes with their long processes in uncalcified cartilage matrices and locate adjacent to the capillary endothelium at the chondro-osseous junction of the growth plate. We have previously revealed a selective expression of epidermal-type fatty acid-binding protein (E-FABP/FABP5) in septoclasts. Although, pericytes are known to distribute along capillaries and directly surround their endothelial cells in a situation similar to septoclasts, no clear evidence is available on the relationship between septoclasts and pericytes...

BACKGROUND: The purpose of this study was to determine the warping angle of the costal cartilage in vivo. METHODS: A nasal framework reconstruction with a rib graft was performed in a total of 130 patients. After the cartilage specimens were prepared, the remaining grafts were used for study. The angle of warping in all grafts was measured at 0, 30, and 60 minutes; after 24 hours; and after 1 week. Eight subgroups of graft thicknesses from central and peripheral groups, determined according to the perichondral distance of the grafts, were evaluated, and the warping angles of 48 osteochondral and chondral grafts were measured individually...

The cranial base is a structure mainly formed through endochondral ossification and integrated into the craniofacial complex, which acts as an underlying platform for the developing brain. Foxc1 is an indispensable regulator during intramembranous and endochondral ossification. In this study, we found that the spontaneous loss of Foxc1 function in a mouse (congenital hydrocephalous), Foxc1ch/ch , demonstrated the anterior cranial base defects, including unossified presphenoid and lack of middle part of the basisphenoid bone...

REVIEW
Maurizio Pacifici
Heparan sulfate (HS) is an essential component of cell surface and matrix proteoglycans (HS-PGs) that include syndecans and perlecan. Because of their unique structural features, the HS chains are able to specifically interact with signaling proteins -including bone morphogenetic proteins (BMPs)- via their HS-binding domain, regulating protein availability, distribution and action on target cells. Hereditary Multiple Exostoses (HME) is a rare pediatric disorder linked to germline heterozygous loss-of-function mutations in EXT1 or EXT2 that encode Golgi-resident glycosyltransferases responsible for HS synthesis, resulting in a systemic HS deficiency...

REVIEW
Akira Yamada
Nagata technique becomes most popular method of autologous rib microtia construction. To achieve successful outcome, 3 keys must be perfect: skin envelope, 3D cartilage framework, and proper location of the construct. The first step of the surgery is to identify "auricular rectangle." Relationship between the auricular rectangle and the vestige will determine if the vestige is usable for surgery. Rib cartilage must be harvested without perichondrium to prevent chest deformity. Lobule split technique is the hallmark of the Nagata technique, which allows skin envelope expansion, and allows deeper conchal cavity...

Vertebral morphology, development, and evolution have been investigated for many decades, especially in the recent evo-devo era. Nevertheless, comparative data on development and ossification modes within the major tetrapod groups are scarce and frequently suffer from the use of a simplistic approach, resulting in simplistic generalizations about the formation of tetrapod vertebrae. Here, we describe the development and ossification of trunk vertebrae in Triturus ivanbureschi (Salamandridae, Caudata) and compare the results with published data on other related taxa...

BACKGROUND: Because of the relatively similar size of organs to human and the physiological and structural similarities, the use of porcine as xenograft donors is progressing very actively. In this study, we analyzed the characteristics of porcine ear cartilage and evaluated its suitability as graft material in reconstructive and cosmetic surgery. METHODS: The auricular cartilage was harvested from two pigs, and subjected to histological examination by immunohistochemical staining...

BACKGROUND: Modern breast reconstruction often involves microvascular reconstruction. The most common recipient vessels are the internal mammary artery and vein. Recently, there has been great focus on efficiency, but much of this emphasis has been directed to faster flap harvest or recovery protocols for expeditious discharge. An equally important aspect is internal mammary vessel preparation. METHODS: Breast reconstruction was performed in 415 patients (715 breasts) using autologous tissue (850 flaps) from 2012 to 2016...
