Arteries that supply the nasal septum and the lateral nasal wall include vessels that originate from the external carotid artery and from the internal carotid artery. A variety of local endonasal pedicle flaps can be used in different anatomical areas for endoscopic skull base reconstruction. The main flaps are based on terminal branches of the sphenopalatine artery and on anterior ethmoidal artery. This study will describe the anatomy of these vessels and their relationship with the main flaps.

Esthesioneuroblastomas are rare neuroectodermally derived neoplasms occurring in the upper nasal septum or cribriform plate. They have been rarely reported in other sites, when they are called ectopic esthesioneuroblastomas. Due to the scarcity of reports, publications and molecular/genetic studies of these tumours, their diagnosis is likely to be missed when they are ectopic. Similar to the case report in this journal by Zahedi et al., we had a case of neuroectodermally derived neoplasm of the tonsil, which was difficult to diagnose, due to the site of occurrence being unknown for these tumours...

Computed tomography X-ray imaging of the internal face in well-preserved primate fossil crania permits reconstruction of the nature of their nasal anatomy, including some soft-tissue features. These features are diagnostic of the primate suborder Haplorhini, and allow reevaluation of the phylogenetic status of several purported early members of the group. Here we examine the nasolacrimal morphology of a broad sample of extant primates, as well as a number of Paleogene fossils. The extant sample confirms the distinctiveness of the two suborders...

We report clinical and pathological features of enzootic nasal adenocarcinoma (ENA) in one sheep in Algeria. A one-year-old Ouled Djellal sheep from a large herd (~1240 animals), located in Bordj Bou Arreridj, Algeria, was clinically diagnosed by the presence of persistent seromucous nasal discharge, head shaking, muzzle licking, dyspnoea, exophthalmia and frontal protrusion. The sheep was euthanized, and the necropsy was performed. Gross examination showed soft touch, pinkish-white tumour masses in the nasal cavities with distortion of the turbinates and of the medium septum...

Septoplasty for a deviated caudal septum is a technique challenging surgery. The two goals of surgery are adequate correction of the deviated septum and maintenance of the nasal tip structural support. Use of an autologous bony crossbar graft to correct a deviate caudal septum offers the following advantages. No difficult drilling or suturing procedure is needed because the graft was kept in place by the elastic properties of the buttonhole cartilage incisions. Second, a simple endonasal approach is sufficient to expose the entire surgical field...

Isolated congenital vomer agenesis is a very rare and poorly understood condition. In the context of dental work-up by cone-beam computed tomography (CBCT), the explored volume of the facial bones occasionally reveals incidental abnormalities. We report the case of a 13-year old Caucasian female who underwent CBCT for the pre-treatment evaluation of primary failure of tooth eruption affecting the permanent right upper and inferior molars. CBCT depicted a large defect of the postero-inferior part of the nasal septum without associated soft tissue abnormality and without cranio-facial malformation or cleft palate...

OBJECTIVE: In wide palatal defects, closure of the nasal layer can prove a considerable challenge. Mobilizing nasal flaps posteriorly usually facilitates soft palate closure. However, the defect is often too wide within the hard palate; hence, bilateral vomerine flaps are frequently required. Despite this, there is often a small defect in the nasal layer at the posterior septum (typically equating to the hard-soft palate junction), which has to be left to heal by secondary intention with the resulting increased risk of fistula formation and the potential deleterious long-term effect on speech due to cicatricial migration of the reconstructed levator sling anteriorly...

INTRODUCTION: Since the introduction of nasal endoscopy into the field of Otorhinolaryngology, the treatment paradigm for cases of severe epistaxis has shifted toward early and precise identification of the bleeding site. Although severe epistaxis is usually considered to arise from posterior bleeding, an arterial vascular pedicle in the superior portion of the nasal septum, around the axilla projection of the middle turbinate, posterior to the septal body, frequently has been observed...

Hemangiopericytomas (HPCs) are uncommon vascular tumors originating from extracapillary cells called pericytes, and rarely occur in the nose or paranasal sinuses. We treated a 57-year-old man with nasal HPC who presented with nasal obstruction and hemorrhage. Nasal endoscopy showed a readily bleeding mass between the right nasal septum and inferior turbinate. Enhanced CT revealed a heterogeneous mass lesion with an enhancement effect that filled the right nasal cavity. A biopsy specimen was proved to exhibit a HPC histopathology...

OBJECTIVE: Nasal septum deviation (NSD) is an anomaly that disturbs normal mucus drainage in sinuses, leading to recurrent sinusitis. Sinusitis, infections, and mucosal irritations are the potential causes of Schneiderian membrane thickening (SMT). The aim of this study was to evaluate the characteristics and association between NSD and SMT along with factors such as age, gender, and tooth groups using cone-beam computed tomography (CBCT) imaging. METHODS: The maxillary sinus and nasal cavity of 249 patients (136 females and 113 males) were examined retrospectively using CBCT...

Patients with a thick nasal skin and soft tissue envelope can have unpredictable results and irregular scarring after rhinoplasty surgery. These patients typically have sebaceous tissue over the nasal tip and are particularly susceptible to soft tissue polly beak formation and excess scar tissue in the radix, tip, and septum. Targeted injections of 5-fluorouracil alone or mixed with low concentrations of steroid can be useful to prevent and treat excess postoperative scar tissue deposition. Ideally, four to six injections are performed every 1 to 4 weeks beginning 1 week postoperatively...

PURPOSE OF REVIEW: Nasal septum perforation (NSP) is a communication between the two nasal cavities. This review contributes to the better knowledge of NSP causes, diagnosis, and treatment. RECENT FINDINGS: NSP prevalence is about 1%. Clinical presentation may range from absence of symptoms to the presence of bothersome sinonasal symptoms. NSP is more frequently caused by trauma or post-surgery, inflammatory diseases, and abuse substances. Conservative management (nasal irrigation, topical use of antibiotic or lubricant ointments, or placement of prosthesis) is considered the first-line treatment...

INTRODUCTION: In rhinoplasty, the nasal dorsum has important relevance regarding the esthetic and functional aspects of the surgery. Its reduction should be performed with maximum accuracy and controlled resection to prevent or minimize potential complications. The Septum Pyramidal Adjustment and Repositioning consists of a conservative surgical technique of the nasal dorsum, which does not require the detachment of the upper lateral cartilages of the nasal septum, allowing the remodeling of the nasal dorsum while maintaining esthetic lines and nasal function, potentially reducing frequent complications in more traditional surgeries...

A schwannoma is a benign tumor arising from Schwann cells present in the nerve sheath of myelinated nerves.It is rarely seen in the nose and paranasal sinuses, and it very rarely originates from the nasal septum. A 40-year-old female presented to our outpatient department with a gradual onset, progressive, left nasal obstruction since the last 4 years. On performing a local examination, a soft tissue mass occupying the left nasal cavity was seen. Surgery via the external approach was performed; the mass was found to arise from the nasal septum and was totally excised...

Schwannoma is an uncommon tumor of nerve sheath that arises from any peripheral, cranial, or autonomic nerve. Only 4% of head and neck schwannomas originate from the sinonasal tract, and a finding of a schwannoma in the nasal septum is exceedingly rare. The authors experienced nasal septal schwannoma with the functional and aesthetic consideration of nasal contour. The authors present an open rhinoplasty approach for nasal septal schwannoma which has not been reported in the previous literature yet.

AIM: Thesurgical success rates of microscopic and endoscopic transsphenoidalapproaches for treatment of hypophyseal adenomas have often been compared. However, little has been reported regarding sinonasal complications of these approaches. We comparedsinonasal complications after microscopic and endoscopic approaches for hypophyseal adenomas. MATERIAL AND METHODS: At our clinic, sinonasal complications occurred in in 31 patients who underwent microscopic transsphenoidal surgery between 2007 and 2014 and in 32 patients who underwent endoscopic transsphenoidal surgery between 2014 and 2016...

Rollin K Daniel, Peter Palhazi
Background: In 1971, Janeke and Wright1 published a now classic study on the support of the nasal tip in which they found four areas of anatomic support. These findings led to the "tripod concept" of tip support. Recently, surgeons have begun repairing and/or preserving the nasal ligaments as a method to control tip projection and rotation. Therefore, a reassessment of the nasal ligaments and tip support is warranted. Objectives: The present study was done to investigate the ligamentous and structural support of the nasal tip...
