Paramedian forehead flap is a workhorse for nasal reconstruction. However, vascular complications may lead to flap failure. The purpose of this study was to evaluate the blood flow objectively and determine the hemodynamic changes in paramedian forehead flap with respect to influential factors of age, gender, and smoking. Thirty patients who had paramedian forehead flap were followed up prospectively between 2010 and 2013. The blood flow was assessed by resistance index using Color Duplex-Doppler Ultrasonography...

PURPOSE: To assess the relationships between optic nerve head drusen (ONHD) volume, retinal nerve fiber layer (RNFL) thickness and visual field (VF) loss. METHODS: Patients with ONHD and no other ocular or systemic conditions that can affect RNFL or VF were enrolled. Serial enhanced depth imaging (EDI) optical coherence tomography (OCT) B-scans of the optic nerve head (interval between scans, ~30 μm) were obtained from each participant. ONHD volume was calculated for each eye by delineating the ONHD masses in each OCT B-scan using 3-dimensional reconstruction software...

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...

Rhinocerebral mucormycosis is an acute, rapidly fatal, fungal infection, classically involving the nasal mucosa and paranasal sinuses. It is an aggressive, opportunistic infection that frequently progresses to involve the orbit and cerebrum. Cerebral extension in immunocompromised patients is almost universally fatal. There are limited data on mucormycosis in pediatric immunocompromised patients in the literature, with only few reports on rhinocerebral involvement. The immunocompromised patients described in this report presented with suspected periorbital and nasal cellulitis, progressing rapidly to necrotic changes in nasal tissue and oral palatal mucosa...

BACKGROUND: Traditional paramedian forehead flap reconstruction exploits the aesthetic subunit principle. Refinements and outcomes of forehead flap nasal reconstruction largely reflect Western experience. Differences in ethnic Asian anatomy and wound healing may foster suboptimal outcomes. We modified methods to address Asian features by extending subunit and flap boundaries, minimizing flap thinning, and overbuilding the nasal framework to combat contraction and suboptimal scarring. METHODS: Between November 2010 and September 2015, 40 Asians were treated for nasal reconstruction with a modified forehead flap technique...

At the Abony-Turjányos dűlő site, located in Central Hungary, a rescue excavation was carried out. More than 400 features were excavated and dated to the Protoboleráz horizon, at the beginning of the Late Copper Age in the Carpathian Basin, between 3780-3650 cal BC. Besides the domestic and economic units, there were two special areas, with nine-nine pits that differed from the other archaeological features of the site. In the northern pit group seven pits contained human remains belonging to 48 individuals...

We report the case of a 65-year old patient presenting with well-defined nodular basal cell carcinom measuring 5mm in diameter in the right paramedian nasal tip and the superior margin of the nasal wing, near the free edge. The tumor was removed, with resection margin of 1mm. It was associated with multiple hyperkeratotic lesions spread across his face. The patient was a farmer with a past history of massive sun exposure. He lived in rural, mountainous and remote regions. The nasal tumor had evolved very slowly and very gradually in volume...

The nasolabial turnover flap was first described by Spear et al in 1987 for the coverage of full thickness defects of the lateral ala. It offered a single-stage repair that recreated the internal nasal lining, the external nasal valve, and the rounded contour of the ala without requiring a cartilage graft. A frequently encountered problem with the execution of Spear's original design is elevation of the ipsilateral commissure of the adjacent lip due to its broad proximal pedicle. Here, the authors describe a fusiform-type design with a proximal, superiorly tapered apex that relies on anteriorly coursing perforators from the underlying angular artery...

Saddle nose deformity is a challenging complication of septoplasty or septorhinoplasty, characterized by underprojected cartilaginous dorsum. Nasal dorsal augmentation is a significant part of reconstructive surgery of saddle nose deformities. In this study, the authors aimed to discuss the results of using toothpick-shaped costal cartilage grafts in nasal dorsal augmentation of saddle nose deformity. Twelve patients who underwent nasal dorsal augmentation due to moderate to severe saddle nose deformity secondary to the previous septoplasty or septorhinoplasty were retrospectively reviewed...

Computer-aided design/computer-aided manufacturing (CAD/CAM) guides are now widely used in maxillofacial reconstruction. However, there are few reports of CAD/CAM guides being used for scapular flaps. The authors performed the secondary maxillary and orbital floor reconstruction using a free latissimus dorsi muscle, cutaneous tissue, and scapular flap designed using CAD/CAM techniques in a 72-year-old man who had undergone partial maxillectomy four years previously. The patient had diplopia, the vertical dystopia of eye position, and a large oral-nasal-cutaneous fistula...

Extant rhinoceroses share the characteristic nasal horn, although the number and size of horns varies among the five species. Although all species are herbivores, their dietary preferences, occipital shapes, and common head postures vary. Traditionally, to predict the "usual" head posture (the most used head posture of animals during normal unstressed activities, i.e., standing) of rhinos, the occipital shape was used. While a backward inclined occiput implies a downward hanging head (often found in grazers), a forward inclined occiput is related to the horizontal head posture in browsing rhinos...

AIM: The paramedian forehead flap (PMFF) has been well described for nasal reconstruction. However, it has never been reported for use in the repair of high flow anterior skull base cerebral spinal fluid (CSF) leaks. MATERIAL AND METHODS: The patient is a 55 yo African American male cocaine abuser who initially presented with a high flow anterior skull base CSF leak, extensive pneumocephalus, and intra-cerebral and intra-ventricular abscesses with an oro-nasal-cerebral fistula...

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...

<b>Background:</b> Fascia wrapped diced cartilage grafts have become a useful tool in modern rhinoplasty surgery. Unfortunately, fascial harvest is associated with donor site morbidity, therefore a non-autologous alternative to fascia would be ideal. Decellularized porcine mesothelium, Meso BioMatrix<sup>TM</sup>, is an acellular scaffold that could potentially fill this need. To determine if porcine mesothelium could serve as an acceptable alternative, we histologically compared diced cartilage grafts wrapped in fascia versus porcine mesothelium...

Typical transcranial approaches are insufficient for adequate visualization and resection of skull base tumors. Different approaches with multiple modifications have been attempted. Here, we describe a new approach for a lesion that is central and hard to treat by conventional craniotomy and successful reconstruction with calvarial bone graft and titanium mesh plate. A 69-year-old female patient presented with recurrent meningioma. The tumor had invaded the frontal lobe, right supraorbital rim, and ethmoidal bone...

Perfect facial and body symmetry is an important aesthetic concept which is very difficult, if not impossible, to achieve. Yet, facial asymmetries are commonly encountered by plastic and reconstructive surgeons. Here, we present a case of posttraumatic facial asymmetry successfully treated with a unique concept of facial flap repositioning. A 25-year-old male patient visited our department with severe posttraumatic facial asymmetry. There was deviated nasal bone and implant to the right, and the actual facial appearance asymmetry was much more severe compared to the computed tomography, generally shifted to the right...

BACKGROUND: The cheek rotation flap has sufficient blood flow and large flap size and it is also flexible and easy to manipulate. It has been used for reconstruction of defects on cheek, lower eyelid, or medial and lateral canthus. For the large defects on central nose, paramedian forehead flap has been used, but patients were reluctant despite the remaining same skin tone on damaged area because of remaining scars on forehead. However, the cheek flap is cosmetically superior as it uses the adjacent large flap...
