Sinonasal papilloma is a common benign epithelial tumor of the sinonasal tract and accounts for 0.5% to 4% of all nasal tumors. The etiology of sinonasal papilloma remains unclear, although human papilloma virus has been proposed as a major risk factor. Other etiological factors, such as anatomical variations of the nasal cavity, may be related to the pathogenesis of sinonasal papilloma, becaus...

Chondrosarcoma is a rare non-epithelial tumor comprising of 10-20% of primary bone tumor. The nasal septum is a rare site for its occurrence. We present one such case of chondrosarcoma of the nasal septum who was treated with endoscopic removal followed by post operative radiotherapy and discuss the relevant clinical presentation, diagnosis and treatment and review the literature also.

While the nasal septum exerts a morphogenetic influence on the facial skeleton, there is evidence that this relationship is highly variable. To better appreciate the precise role of the septum, it is important understand the variable interaction between the septum and surrounding skeleton during ontogeny. Here we analyzed nasal septal and facial skeletal postnatal phenotypic variation using cro...

Background. Eosinophilic angiocentric fibrosis (EAF) is a rare benign condition of unknown aetiology that causes stenosis of the upper respiratory tract. It is most commonly found at the nasal septum and sinus mucosa causing mucosal thickening and nasal obstructive symptoms. The diagnosis is mainly based on characteristic histologic findings. Case Report. A 27-year-old young woman presented wit...

INTRODUCTION  The cocaine is obtained from the leaves of the coca (Erythroxylon coca). It can be used in many ways, but the most common is the drug inhalation. The Cocaine also causes vasoconstriction at nasal mucous membrane and its chronic use can cause necrosis and nasal septum perforation. Pyoderma gangrenosum is an uncommon idiopathic disease characterized by ulcerations, usually observed ...

BACKGROUND The septal cartilage is the most useful donor site for autologous cartilage graft material in rhinoplasty. For successful nasal surgery, it is necessary to understand the developmental process of the nasal septum and to predict the amount of harvestable septal cartilage before surgery. METHODS One hundred twenty-three Korean patients who underwent three-dimensional (3D) facial bone...

BACKGROUND Teratoma is a rare developmental neoplasm that arises from totipotential tumor stem cells. Head and neck teratomas constitute about 10% of all cases. Only two cases of mature teratoma of the nasal septum have previously been documented in the world literature. CASE PRESENTATION We present a case of histologically confirmed mature teratoma arising from the nasal septum in an eightee...

Introduction: Teratomas are neoplastic tumors derived from totipotent germ cells containing a wide assortment of tissues originating from all three germ cell layers. Teratomas can be mature or immature depending on the presence of immature tissues; typically neuroepithelial tissue. Immature teratomas can be oncologically benign or malignant, and can be divided into three grades with increasingl...

AIM Major complications of microscopic transnasal hypophyseal surgery (MTHS), such as cerebrospinal fluid rhinorrhea, carotid injury, and optic nerve injury, are very rare. However, late rhinological complications can be ignored because they are a minor cause of morbidity compared with major complications. In this study, we extensively examined postoperative rhinological complications in patien...
