To determine if facial plastic and reconstructive surgeons still adhere to the classic nasal subunit principle as described by Burget and Menick. Observational survey. A Weill Cornell Medicine institutional review board approved electronic survey that was sent via e-mail to active members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS). The survey consisted of 32 multiple-choice questions pertaining to the operative management of small (22-30%), medium (50-58%), and large (75-81%) defects of each subunit of the nose, as well as demographic, provider, and practice characteristics...

Nasal reconstruction for subtotal and total rhinectomy defects is a challenging endeavor, which requires technical finesse, a keen artistic eye, and the ability to anticipate long-term changes that accompany postoperative healing. While local and regional flaps have traditionally been utilized to reconstitute missing nasal elements, certain situations may not provide sufficient or acceptable tissue for optimal reconstruction. In these situations, the three major components of the nose-lining, structural support, and external skin-may require reconstruction with tissues harvested from distant sites through microvascular free tissue transfer...

The challenges of nasal reconstruction are readily apparent to any surgeon who has undertaken this task. Defects involving multiple subunits of the nose usually require adjacent tissue transferred to the wound typically in the form of a forehead flap or other local flaps. Herein, we describe current thought on the subunit principle and the application of local flaps and grafts in reconstructing larger superficial defects of the nose. Primary attention is paid to analysis and patient counseling.

The nose is a complex, three-dimensional structure that is supported by a framework of osseous and cartilaginous structures. Disruption of this framework can result in nasal deformity and functional deficits. Nasal reconstruction requires restoration of the osseous and cartilaginous framework. This requires careful preoperative assessment of the nasal defect and understanding the nasal and facial aesthetics that are supported by the osseous and cartilaginous support structures. Structural grafts can be classified as restorative, supportive, or contouring...

Nasal reconstruction has been articulated in the literature since 700 B.C. when the earliest iteration of the forehead flap was described in the Indian medical treatise, the Sushruta Samhita. Since then it has evolved into the interpolated flap which has served as a powerful tool for facial reconstruction. The interpolated flap is constructed from nonadjacent donor tissue that has an inherent blood supply. It requires a multistaged approach and is best suited for reconstruction of large or deep defects of the nose...

The rise in cutaneous malignancies over the past 20 years has led to significant advances in reconstructing the nose from an aesthetic and functional standpoint. The principles of nasal reconstruction center on application of the nasal subunit principle, three-layered reconstruction, nasal skin characteristics, and patient factors. Reconstructive planning starts with proper defect analysis, followed by application of the reconstructive ladder for soft-tissue repair, adequate structural support, and repair of nasal lining deficits...

The nose is a complex structure important in facial aesthetics and in respiratory physiology. Nasal defects can pose a challenge to reconstructive surgeons who must re-create nasal symmetry while maintaining nasal function. A basic understanding of the underlying nasal anatomy is thus necessary for successful nasal reconstruction.

BACKGROUND: Nasomaxillary hypoplasia is a rare congenital disorder involving the central face. It imparts a distinctive appearance to the individual face as the age advances. Severity of the disorder varies, so do the manifestations. METHODS: This was a retrospective study conducted on the records and photographic data of 560 rhinoplasty cases performed between 2006 March and 2016 March. About 16 cases of nasomaxillary hypoplasia were selected from the group and they were classified based on the severity of the features...

BACKGROUND: The ala of the nose is vascularized by a dense net of perforators originating from the lateral nasal artery or the angular artery. These vessels reach the ala in a cascade fashion from the alar groove/lateral nasal wall. Based on these vessels, a V/Y flap can be dissected with a wide range of mobility. MATERIALS AND METHODS: Nineteen patients underwent reconstruction of the nose by means of a V/Y-alar-perforator flap alone or in combination with a myocutaneous rotation flap from the lateral nasal wall and/or from the nasal dorsum for reconstruction of defects at the nasal tip, ala of the nose, and/or lateral nasal wall...

The orientation of the semicircular canals of the inner ear in the skull of vertebrates is one of the determinants of the capacity of this system to detect a given rotational movement of the head. Past functional studies on the spatial orientation of the semicircular canals essentially focused on the lateral semicircular canal (LSC), which is supposedly held close to horizontal during rest and/or alert behaviors. However, they generally investigated this feature in only a few and distantly related taxa. Based on 3D-models reconstructed from µCT-scans of skulls, we examined the diversity of orientations of the LSC within one of the four major clades of placental mammals, that is, the superorder Xenarthra, with a data set that includes almost all extant genera and two extinct taxa...

The risk of cancer is significantly increased in patients undergoing renal transplant surgery than in the general population. In particular, skin cancer is the most commonly occurring cancer in these patients.A 34-year-old man underwent living renal transplantation for focal segmental glomerulosclerosis. After 18 months, he developed a lesion on the nasal dorsum, approximately 1 cm in size, and the lesion rapidly expanded to cover the entire dorsum.Owing to its rapid expansion, the lesion was suspected to be a malignant tumor and wide excision was planned...

OBJECTIVES: Endoscopic approach provides excellent magnification and visualization, and a purely transnasal approach is minimally invasive method. However, it is very difficult to repair anterior and lateral fractures with the previous transnasal endoscopic approaches, since repair of orbital fractures is managed through the middle meatus and ostium from the posterior side of the nasolacrimal duct with side-viewing endoscope and curved instruments. Therefore, the authors used modified transnasal endoscopic approach as an alternative for repair of orbital floor fractures in order to effectively reach the lateral or anterior fracture of the orbital floor with straight endoscope and instruments endoscopically...

PURPOSE: To propose a computerized framework for localization of anatomical feature points on the patient surface in infrared-ray based range images by using differential geometry (curvature) features. METHODS: The general concept was to reconstruct the patient surface by using a mathematical modeling technique for the computation of differential geometry features that characterize the local shapes of the patient surfaces. A region of interest (ROI) was firstly extracted based on a template matching technique applied on amplitude (grayscale) images...

The buccinator flap is currently one of the best techniques for the reconstruction of defects in the oral cavity and other sites. Reconstruction of the palate is a major challenge because of the functional consequences of the excision of lesions in this area. The main goal is to maintain separation between the mouth and the nose. We have done a cross-sectional retrospective descriptive study of a series of cases reconstruction of palatal defects with buccinator flap at the University Hospital Miguel Servet in Zaragoza during a six-year period and compared our results, morbidity, and mortality with those of published series...

Revision rhinoplasty in Asian patients is associated with problems related to the use of grafts or implant materials. Moreover, the septal cartilage of Asian individuals is generally weak and small, which makes it particularly vulnerable to injury or secondary deformity during primary surgery. Hence, there is an increased demand for major reconstruction of the septal cartilage framework during revision surgery in Asian patients. In revision rhinoplasty of the nose in Asian patients, appropriate management of the graft or implant is vital...

Numerous beautiful rhinoplasty results have been created by closed rhinoplasty techniques over the past 100 years. This operation was mainly a "reduction" surgery. Overaggressive reduction rhinoplasty is not a hallmark of the closed approach per se, but represents the result of inappropriate aesthetic appraisal, inadequate technical execution, or lack of sound anatomical understanding. Clearly, an operation based primarily on reduction intrinsically exposes the surgeon to the possibility of excessive diminution of support structures and consequently undesirable side effects...

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...

Importance: Repairing the saddle nose deformity in the setting of granulomatosis with polyangiitis disease is a rare but challenging situation for any surgeon. Given that the available data in the literature is based on case reports and small case series, there is little evidence available to help delineate which reconstructive techniques are optimal. Objective: To examine which techniques were most successful in reconstructive rhinoplasty for a saddle nose deformity secondary to granulomatosis with polyangiitis...
