The implantation of autologous cartilage as the gold standard operative procedure for the reconstruction of cartilage defects in the head and neck region unfortunately implicates a variety of negative effects at the donor site. Tissue-engineered cartilage appears to be a promising alternative. However, due to the complex requirements, the optimal material is yet to be determined. As demonstrated previously, decellularized porcine cartilage (DECM) might be a good option to engineer vital cartilage. As the dense structure of DECM limits cellular infiltration, we investigated surface modifications of the scaffolds by carbon dioxide (CO2) and Er:YAG laser application to facilitate the migration of chondrocytes inside the scaffold...

OBJECTIVES/HYPOTHESIS: Endonasal surgeries are the primary cause of septal perforation (SP). However, trauma, inflammation, infections, neoplasms, or abuse of inhaled drugs can also cause SP. Septal repair is indicated in patients who experience nasal obstruction, crusting, intermittent epistaxis, purulent discharge, or nasal whistling and in those who fail conservative treatment. Multiple approaches have been suggested to repair the SP; however, none has been universally adopted. This study explores the feasibility of repairing a total SP using the pericranial flap (PCF)...

The aim of this pictorial review is to describe the technical advances achieved through the application of 4-dimensional (4D) ultrasound using spatiotemporal image correlation (STIC) over conventional 2-dimensional ultrasound in the prenatal detection of congenital heart disease (CHD). Spatiotemporal image correlation is a volume imaging technique that simplifies fetal heart studies while providing more diagnostic information than is typically available from traditional 2-dimensional studies. Four-dimensional software allows the study of cardiac anatomy and function during a single cardiac cycle and has greatly contributed to diagnostic enhancement of CHD...

IMPORTANCE: Severe dorsal deviations in crooked noses are treated by either in situ septoplasty with asymmetric spreader grafts (ISS) or extracorporeal subtotal septal reconstruction (ECS). To our knowledge, except one retrospective study, there is no other that compares the objective and subjective results of these two treatment modalities. OBJECTIVE: The aim of this study was to compare the aesthetic and functional outcomes of ECS and ISS in crooked noses. DESIGN, SETTING AND PARTICIPANTS: This study was carried out on 40 patients (ISS in 20 patients and ECS in 20 patients) who underwent external rhinoplasty surgery due to crooked noses between May 2014 and January 2016...

Suspensory femoral graft fixation has been a popular and reliable method in anterior cruciate ligament (ACL) reconstruction. Some authors have introduced suspensory femoral fixation in posterior cruciate ligament (PCL) reconstruction using inside-out (IO) technique. The use of IO technique for femoral tunnel preparation could significantly sharpen the critical corner, which might result in graft failure. A retrograde drilling pin that recently has been popular in ACL reconstruction allows "no incision" in the outside-in (OI) technique for the creation of a femoral socket...

Nasal continuous positive airway pressure (nCPAP) is utilized increasingly to treat pulmonary immaturity in premature neonates. Nasal injury is common with nCPAP use, with full thickness tissue loss at the columella among the most devastating complications.Columellar necrosis often imparts a full thickness injury to the overlying columellar skin, the medial crura of the lower lateral nasal cartilages, as well as the anteromedial inner nasal mucosal lining, and potentially the anterior septal cartilage. Consequently, the columella can become scarred and shortened...

BACKGROUND: The nasoseptal flap (NSF) is a universally used surgical technique to cover defects of the skull base after extended sinonasal surgery. Long-term follow-up of complications, sequelae, and smell function is largely unknown. OBJECTIVE: The main objective of this study was to investigate monorhinal olfaction after transsphenoidal skull base surgery. METHODS: Patients who underwent skull base surgery for midline lesions (craniopharyngioma and pituitary tumors) by using a NSF, also referred to as the Haddad flap, were assessed for their long-term outcome...

BACKGROUND: The employment of 2-octylcyanoacrylate adhesive (Dermabond) to assist graft placement in open septorhinoplasty has been increasingly used to stabilize cartilage grafts. Literature regarding this application has been mixed, with some showing the possibility of increased rates of inflammation, if not infection. We present an original comparative case series involving postoperative septal abscess formation adjacent to caudal strut grafting where both Dermabond and an absorbable polydioxanone (PDS) plate were used...

Successful reconstruction of the oromandibular defect with the osteoseptocutaneous fibula flap necessitates flawless design and inset, an experience-demanding endeavor. Laterality of the fibula flap has been thought to pose a certain challenge to the reconstruction. To address this concern and guide flap design and inset, the authors propsed using the surgeon's fist with the thumb up to replicate key anatomic land marks of the fibula flap: the peroneal vessels and proximal bone end, the posterior crural septum including the septal vessels, the skin, and the lateral surface of the fibula bone...
