BACKGROUND: The status of current evidence for the effectiveness of septoplasty is unclear. This systematic review evaluates the effectiveness of a) septoplasty (with or without concurrent turbinate surgery) versus non-surgical management, and b) septoplasty with concurrent turbinate surgery versus septoplasty alone, for nasal obstruction due to a deviated nasal septum in adults. METHODOLOGY: Eligible for inclusion were randomised controlled trials and non-randomised designs comparing treatment strategies...

BACKGROUND: Upon orthognathic mandibular advancement surgery the adjacent soft tissues can displace the distal bone segment and increase the load on the temporomandibular joint causing loss of its integrity. Remodeling of the condyle and temporal fossa with destruction of condylar cartilage and subchondral bone leads to postsurgical condylar resorption, with arthralgia and functional limitations. Patients with severe lesions are refractory to conservative treatments, leading to more invasive therapies that range from simple arthrocentesis to open surgery and prosthesis...

Loss of nasal skin as well as loss of both lateral alar cartilages and vestibular lining with exposure of septum presents a grotesque deformity by itself, with further danger of loss of nasal bones and other cartilaginous structures leading to total loss of nose. The Goal of the treatment is to restore the skin cover as well as lining and cartilage support, restoring nose while avoiding the deformity. In an elderly patient with Spiritual restrictions, with diabetes and Hypertension, the treatment was needed to be carried out under local anesthesia as a daycare procedure...

BACKROUND: Increasing indications for endoscopic endonasal approaches have led neurosurgeons to develop new reconstruction techniques for larger skull base defects. Vascularized grafts have been a great adjunction to reduce the rate of cerebrospinal fluid leak and can also be used to cover exposed critical structures such as the internal carotid artery. The nasoseptal flap and the inferior or middle turbinate flap are thus widely used in endoscopic skull base surgery, but may be insufficient for very large defects...

OBJECTIVES: A relatively neglected aspect of cleft lip nasal deformity is the effect of septal deviation and inferior turbinate hypertrophy (ITH) on the functional airway. In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH...

OBJECTIVE: Concha bullosa is generally regarded as pneumatisation of the middle turbinate in the nose. However, pneumatisation may also be seen in the superior and inferior turbinate. Computed tomography (CT) of paranasal sinuses is extremely helpful for the examination of this inaccessible area. Coronal CT sections of paranasal sinuses are particularly useful for surgical anatomy, as these images show nearly the same regions as the endoscopic examinations. The aim of this retrospective study was to evaluate the presence, incidence and unilaterality-bilaterality of superior turbinate pneumatisation and concomitant nasal pathologies...

The complex nasal structure poses obstacles for efficient nasal drug administration beyond the nasal valve, especially when targeting the olfactory region. This study numerically detailed the naturally inhaled nanoparticle transport process from the initial releasing locations to the final deposited sites using a realistic human nasal passage. Dispersed nanoparticles at different coronal cross-sections were partitioned into multiple groups according to their final deposited locations. Results showed inhaled nanoparticles are more likely to move along the septum...

The most common benign tumour of the major salivary glands is the pleomorphic adenoma. They are seen rarely in the minor salivary glands, usually in hard palate, soft palate and nasopharynx. Pleomorphic adenomas in nasal cavity are unusual and may be misdiagnosed because they have predominant myoepithelial cellularity and fewer myxoid stromata compared with those elsewhere. We present a case of 38-year-old male with a 2-year history of left nasal obstruction and epistaxis since 6 months. Diagnostic nasal endoscopic examination showed a soft lobulated mass in left nasal cavity attached to anterior part of the septum...

The Grueneberg organ (also termed Grueneberg ganglion) is an olfactory subsystem at the rostral nasal septum of rodents, and has been suggested to exist also in humans. Grueneberg organ neurons respond to coldness and alarm pheromones, but the anatomical arrangement and regenerative capacity are not fully characterised. We examined the relationship between the glia and the neurons using crosses of two transgenic mouse lines, S100ß-DsRed and OMP-ZsGreen, to visualise olfactory ensheathing cells (OECs) and Grueneberg olfactory neurons, respectively...

INTRODUCTION: Combined mid-face and nasal apparatus trauma injuries pose a significant challenge to airway patency (AW), in the immediate postoperative setting following fracture reduction. As such, the authors describe a modified technique with the goal of maintaining a patent nasal AW, while at the same time, minimizing nasopharyngeal bleeding and nasal AW edema-which can complicate patients requiring intermaxillary fixation (IMF) in the setting of pan-facial trauma. METHODS: A modified technique was devised to assist the reconstruction surgeon in avoiding the risks associated with tracheostomy placement...

A perforation in posterioinferior portion of nasal septum is rare and caused by vomeral defect. We report a case of 56-year-old man who had a vomer defect, which was detected incidentally during preoperative evaluation of nasal septoplasty and turbinoplasty. The patient had a surgery of septoplasty and bilateral turbinoplasty under general anesthesia. There was no septal mucosal tear or defect during septoplasty and turbinoplasty. When the patient who has vomeral defect with nasal obstruction is planned for septoplasty and turbinoplasty, the surgery should be performed carefully to protect the mucosa...

OBJECTIVE: The purpose of this research is to examine the changes in nasal airflow dynamics before and after the nasal perforation repair. METHODS: Three dimensional (3D) models of the nasal cavity before and after septal perforation repair was reconstructed using preoperative and postoperative computed tomography (CT) images of a patient. The numerical simulation was carried out using ANSYS CFX V15.0. Pre- and post-operative models were compared by their velocity, pressure (P), pressure gradient (PG), wall shear (WS), shear strain rate (SSR) and turbulence kinetic energy (TKE) in three plains...

IMPORTANCE: Spreader grafts are commonly used for nasal valve stenosis. There is debate among practitioners regarding the optimal approach for spreader graft placement. OBJECTIVE: This study aimed to determine whether an endonasal spreader graft placement leads to equivalent postoperative outcomes using a standardized nasal obstruction symptom score and whether there is a significant difference in operative time between the 2 approaches. DESIGN: A retrospective review of functional rhinoplasties by a single facial plastic surgeon over a 2-year period was conducted...

OBJECTIVE: To define and quantify common points and relationships within the anterior nasal septum and recognize the anatomic curvature of the dorsal and caudal septum as arcs with certain rises. STUDY DESIGN: Case series study. METHODS: Forty cadaveric quadrangular cartilages were dissected. Points along the septum were defined and relationships measured. Angles that composed the anterior septum using values that did account for the curvature of the anterior nasal septum, or classical L-strut values, were compared to C-strut values, which included rises away from the L-strut...

Supernumerary teeth are an uncommon occurrence that have the ability to arise anywhere in the dental arch. Mesiodens is a specific type of supernumerary tooth that occurs in the vicinity of the maxillary central incisors. Mesiodens are the most common among all supernumerary teeth, almost always impacted, and may also be seen in various positions based on the eruption status. The formation of mesiodens is a much-debated topic and many theories have been proposed. The reports also include its common radiographic findings and a pertinent literature review...

Background: While effective for the repair of large skull base defects, the Hadad-Bassagasteguy nasoseptal flap increases operative time and can result in a several-week period of postoperative crusting during re-mucosalization of the denuded nasal septum. Endoscopic transsphenoidal surgery for pituitary adenoma resection is generally not associated with large dural defects and high-flow cerebrospinal fluid (CSF) leaks requiring extensive reconstruction. Here, we present the posterior nasoseptal flap as a novel technique for closure of skull defects following endoscopic resection of pituitary adenomas...

Despite progress made in nasal reconstruction, the restoration of a large defect, including the whole septum and mid-nasal vault structures, remains a challenge. The pericranial flap (PCF) is used widely for the reconstruction of anterior cranial fossa defects. This article presents a surgical technique for nasal lining restoration with an endoscopic PCF design. This technique was used in patients with huge intranasal tumours. Two patients with nasal eosinophilic angiocentric fibrosis were treated. The structural involvement was similar in each case...
