REVIEW
Katsuhiro Okuda, Ryoichi Nakanishi
Surgical treatment for lung cancer including airway resection following reconstruction is typically performed under general anesthesia with single-lung ventilation because it is necessary to maintain a sufficient working space and to adjust the airway pressure for the leak test. However, non-intubated thoracic surgery has been gradually developed in recent years for thoracoscopic surgery, due to its lower rate of postoperative complications, shorter hospitalization duration, and lower invasiveness than the usual single-lung anesthesia...

Objective To compare the Ambu Aura-i with the Air-Q intubating laryngeal airway for fiberoptic-guided tracheal intubation in ear deformity children.Methods Totally 120 children who were scheduled for elective auricular reconstruction surgery requiring general anaesthesia with tracheal intubation were enrolled in this prospective study. They were randomized to receive either the Ambu Aura-i (Aura-i group) or Air-Q (Air-Q group). The time for successful tracheal intubation was assessed. The attempts for successful device insertion, leak pressures, cuff pressures, fiberoptic grade of laryngeal view, time for removal of the device after endotracheal intubation, and complications were recorded...

The feasibility of computational fluid dynamics (CFD) to evaluate airflow characteristics in different head and neck positions has not been established. This study compared the changes in volume and airflow behavior of the upper airway by CFD simulation to predict the influence of anatomical and physiological airway changes due to different head-neck positions on mechanical ventilation. One awake volunteer with no risk of difficult airway underwent computed tomography in neutral position, extension position (both head and neck extended), and sniffing position (head extended and neck flexed)...

PURPOSE OF REVIEW: The aim of this study was to describe the most recent technical nuances for resection and reconstruction of Grade 1 and 2 laryngeal chondrosarcomas, with a special emphasis on those located at the level of the cricoid plate, which is the site of origin of the vast majority of these rare tumours. RECENT FINDINGS: Even though inherently based on retrospective small clinical series or anecdotal case reports, a number of studies have been recently published focusing on conservative transoral and open-neck surgical procedures aimed at an oncologically sound removal of the tumour together with organ and function preservation...

Aparna Dalal
Face transplantation is a complex vascular composite allotransplantation (VCA) surgery. It involves multiple types of tissue, such as bone, muscles, blood vessels, nerves to be transferred from the donor to the recipient as one unit. VCAs were added to the definition of organs covered by the Organ Procurement and Transplantation Network Final Rule and National Organ Transplant Act. Prior to harvest of the face from the donor, a tracheostomy is usually performed. The osteotomies and dissection of the midface bony skeleton may involve severe hemorrhagic blood loss often requiring transfusion of blood products...

Thoracoscopic pulmonary lobectomy (TPL) techniques in infants and children are presented practically with concise descriptions and numerous illustrations. TPL is the treatment of choice for congenital pulmonary airway malformation and intralobar pulmonary sequestration, both now commonly diagnosed prenatally. Timing of surgery is somewhat controversial in asymptomatic cases with small isolated lesions. Incomplete fissures and history of chest infections are most problematic. Thorough understanding of anatomic relations preoperatively is vital for successful outcome and thin-slice computed tomography with 3D reconstruction of vessels is valuable...

We present a case of impassable subglottic stenosis scheduled for tracheal resection and reconstruction managed by establishing a supraglottic airway. Despite careful preoperative evaluation, the stenosis was localized higher than anticipated, rendering conventional intubation impossible. Laryngeal mask bridging to cross-field ventilation was feasible and jet ventilation and cardiopulmonary bypass were available as emergency strategies. Surgery and emergence went uneventful. Perioperative considerations are discussed in this report...

The importance of the nasal complex cannot be overstated from a functional, social, and psychological perspective. The goal of reconstruction is to restore the trilaminar composition of the nose. This is accomplished by recreating the nasal lining and providing a cartilaginous framework to simultaneously support a patent airway and project the defining features to the overlying soft tissue. The columella is one of the smallest subunits of the nose, but the loss of this structure has important esthetic and structural implications...

Though a life-saving modality in neonatal intensive care units, nasal continuous positive airway pressure (nCPAP) carries a small risk of irreversible ischemia and necrosis of the columella due to the configuration of the pressure delivery system. Iatrogenic injuries to the columella after nCPAP use result in a spectrum of disfigurement and functional airway obstruction. The authors performed a retrospective review of patients evaluated for nCPAP-related columellar deformities by the Division of Plastic and Reconstructive Surgery at the authors' institution over a 10-year period to assess reconstructive outcomes...

BACKGROUND: Reconstruction of long-segment tracheal defects can be challenging and a suitable tracheal substitute remains lacking. We sought to create a bioengineered tracheal graft to repair such lesions using acellullar bovine dermis extracellular matrix (ECM) and male human mesenchymal stem cells (hMSCs) and implant it in a porcine model. METHODS: hMSCs were seeded on the ECM and incubated for 1 week with chondrogenic factors. An anterior 4 cm × 3 cm defect was surgically created in the trachea of 4-week-old female Yorkshire pigs...

We conducted a retrospective study to assess the efficacy of using a nasopharyngeal airway in lieu of a tracheotomy or prolonged intubation for the diversion of airflow to prevent tension pneumocephalus after an open resection of anterior skull base tumors. Our study population was made up of 120 patients-74 males and 46 females, aged 12 to 84 years (mean: 48.7)-who had undergone an anterior skull base resection with documented nasopharyngeal airway placement from 1996 through 2009. Our main outcome measure was the presence of tension pneumocephalus while controlling for the placement of a lumbar drain, the development of a cerebrospinal fluid (CSF) leak, and the type of reconstruction...

The treatment of long-segment tracheal defect requires the transplantation of effective tracheal substitute, and the tissue-engineered trachea (TET) has been proposed as an ideal tracheal substitute. The major cause of the failure of segmental tracheal defect reconstruction by TET is airway collapse caused by the chondromalacia of TET cartilage. The key to maintain the TET structure is the regeneration of chondrocytes in cartilage, which can secrete plenty of cartilage matrices. To address the problem of the chondromalacia of TET cartilage, this study proposed an improved strategy...

Respiratory viral infections are a leading cause of disease and mortality. The severity of these illnesses can vary markedly from mild or asymptomatic upper airway infections to severe wheezing, bronchiolitis or pneumonia. In this article, we review the viral sensing pathways and organizing principles that govern the innate immune response to infection. Then, we reconstruct the molecular networks that differentiate symptomatic from asymptomatic respiratory viral infections, and identify the underlying molecular drivers of these networks...
