Revision rhinoplasties and saddle nose deformities usually require grafting for reconstruction. Between January 1, 2000, and January 1, 2017, autologous rib grafts were used in 127 secondary and tertiary rhinoplasty patients [(57/127 females) and (70/127 males)]. Osseous-cartilaginous rib grafts (OCRGs) were divided into three parts (i.e., 1/3 upper peripheral, 1/3 central, and 1/3 lower peripheral). The harvested OCRGs were also shaped as vertical strips using a number 11 scalpel blade. These OCRGs were shaped to form the L-strut cartilaginous graft (LSCGs), osseous-cartilaginous spreader grafts (OCSGs), osseous-cartilaginous onlay grafts, nasal valve grafts (NVGs), and lower lateral cartilaginous grafts (LLCGs)...

Obstructive sleep apnoea (OSA) results from the recurrent collapse of the upper airway during sleep. Nasal abnormalities influence the stability of the pharynx. The aim of this study was to evaluate the volumetric and anatomical changes of the nasal cavity in patients with OSA. The Nasal Obstruction Symptom Evaluation (NOSE) scale was used to grade nasal obstruction. Sleep-related breathing disorders were evaluated by polysomnography. The nasal airway volume was obtained from computed tomography scans through volumetric reconstruction of the nasal airway...

INTRODUCTION: Fronto-metaphyseal dysplasia (FMD), also called Gorlin-Cohen syndrome, is a rare syndrome initially described in 1969 by Gorlin and Cohen. Patients present skeletal dysplasia, craniofacial malformations and digit abnormalities. Craniofacial phenotype of FMD is characterized by supraorbital hyperostosis, hypertelorism, down-slanting palpebral fissures, broad nasal bridge and micrognathia. Here, we report the first adult case of craniofacial reconstruction with frontal cranioplasty in a patient with FMD...

Nasal columella defects can significantly impair aesthetic appearance. Columella reconstruction can be very challenging for surgeons, especially if due to cocaine abuse. The case of a 32-year-old male patient with subtotal columellar necrosis secondary to cocaine abuse is presented. An inferiorly based philtral advancement flap was performed to cover the defect. Aesthetic outcome was the primary goal of surgery. Reconstruction led to good aesthetic and functional results.

Rhinophyma is characterized by nodular thickening of the Nasal skin, sebaceous gland hyperplasia, dilated pores, and in its late stage, fibrosis. In severe cases, it results in loss of normal facial contours, significant disfigurement, and social isolation. Treatment options for severe rhinophyma include cryosurgery, partial-thickness decortications with subsequent secondary reepithelialisation, laser ablation, full thickness resection with graft or flap reconstruction, excision by electrocautery or radio frequency...

PURPOSE: Although a variety of mathematical observer models have been developed to predict human observer performance for low contrast lesion detection tasks, their predictive power for high contrast and high spatial resolution discrimination imaging tasks, including those in CT bone imaging, could be limited. The purpose of this work was to develop a modified observer model that has improved correlation with human observer performance for these tasks. METHODS: The proposed observer model, referred to as the modified ideal observer model (MIOM), uses a weight function to penalize components in the task function that have less contribution to the actual human observer performance for high contrast and high spatial resolution discrimination tasks...

BACKGROUND: Reconstruction of the nasal lining is the most difficult part of complex nasal reconstruction because the mucosa has a unique texture and fineness. Many techniques, ranging from skin grafts to local flaps, have been applied for the reconstruction of the mucosa. In some cases, even free flaps have been used. OBJECTIVE: The aim of this study was to discuss the feasibility of using turn-in flaps in nasal reconstruction. MATERIALS AND METHODS: Seventeen patients with full-thickness nasal defects underwent reconstruction with turn-in flaps...

PURPOSE OF REVIEW: To review current surgical practices of lower eyelid reconstruction with a focus on recent studies. RECENT FINDINGS: Combination techniques and new flap techniques offer efficacy comparable with existing reconstructive approaches, with the advantage of less local trauma. Inappropriate handling of posterior lamellar grafts, such as kerfing, may predispose to graft failures. Modified Hughes procedure is a favorable choice for large lower eyelid reconstruction; however, it requires temporary eye closure...

BACKGROUND: The time course of rhinovirus positive and negative rhinosinusitis has not been quantified yet, which aggravates proper selection and justification of the optimum treatment for this illness. Such quantitative information would facilitate an early and proper identification of the disease and its differentiation from acute bacterial rhinosinusitis, and could diminish harmful overuse of antibiotics, arguably driven by patients' want for attention and the treating physicians' inability to offer an adequate verbal comfort in its stead...

Conventional dental implants have been reported for nasal and orbital regions but due to limited thickness of calvarium they are not used in mastoid region. Onlay bone grafting in skull concomitant with implants is a predictable method and experimental animal studies confirm it. Parietal bone and lateral mandibular ramus are suggested source of bone grafts and dental implants with 7 mm length can be used safely. Increased fixture length may lead to increase survival in long term.

A 36-year-old man presented because of nasal obstruction, rhinorrhea, and postnasal drip. The patient had undergone reconstruction of a blow-out fracture of the orbital floor 12 years before and had sinusitis that likely had resulted from implant migration into the maxillary sinus. The inflammation was successfully resolved, and the implant was removed through a minimally invasive endoscopic sinus surgery technique. On pathologic examination, an organizing hematoma was identified as the cause of the lesion...

A polyglycolic acid-collagen (PGA-c) tube was used as an artificial nerve guide during facial nerve reconstruction performed in a canine model of stellate ganglion block (SGB). The model was generated using a cervical sympathetic ganglionectomy. We evaluated the effects of blood flow on nerve regeneration. First, we resected the left cervical sympathetic ganglion in beagles (n = 6). We assessed buccal mucosal blood flow and nasal skin temperatures once per week for 12 weeks and Horner's sign 2, 4, and 6 months after resection...

BACKGROUND: Irregularities or deformities of the nasal dorsum after hump reduction account for a significant number of revision rhinoplasties. We therefore developed a technique of meticulously dicing and exactly placing free diced cartilage grafts (fDC), harvested from septum, rib, or ear cartilage. The cartilage paste is used for smoothening, augmentation, or camouflaging of the nasal dorsum in primary or revision rhinoplasties. METHODS: A retrospective analysis of multi-surgeon consecutive open approach rhinoplasties from January to December 2014 was conducted at a single center...

Importance: The paramedian forehead flap is considered the gold standard procedure to optimally reconstruct major defects of the nose, but this procedure generally requires 2 stages, where the flap pedicle is divided 3 weeks following the initial surgery to ensure adequate revascularization of the flap from the surrounding recipient tissue bed, which can cost a patient time out of work or away from normal social habits. It has previously been shown that the pedicle may be safely divided after 2 weeks in select patients where revascularization from the recipient bed was confirmed using intraoperative laser fluorescence angiography to potentially save the patient time and money...

BACKGROUND: Numerous methods exist for repairing unilateral cleft lips and mainly focus on cutaneous design to achieve sufficient rotation of the medial (M) cleft lip and produce a natural Cupid's bow and philtrum. However, precise nasal floor reconstruction has not been described in detail. This is the first study to introduce a technique for repairing complete unilateral cleft lips with a focus on nasal floor reconstruction. METHODS: In our technique, "Straight-Line Advanced Release Technique (StART)," the nasal floor is considered a 3-dimensional cuboid structure; the M mucosal and lateral (L) mucosal flaps constituted the posterior surface...
