Abstract Background: Nasal tuberculosis (NTB) is rare, but it can be caused by either a pulmonary disease or a retrograde involvement of the nose by lupus vulgaris of the facial skin. In this study, we present a case of NTB with an ulcerative lesion in her left nasal cavity. Case presentation: A 56 years old woman presented with an ulcerative lesion in her left nasal cavity. The patient exhib...

INTRODUCTION A case report showing the removal of a supernumerary tooth from the nasal cavity by means of an endoscopic approach is presented. MATERIALS AND METHODS A 9-year-old healthy child presented to our department because of the right central incisor which appeared clinically rotated. The observation of orthopantomography revealed the presence of a supernumerary tooth in the anterior ma...

A 17-year-old patient with no specific pathological history who consulted for epistaxis with low abundance repetitions by the left nasal fossa associated with a homolateral stuffy nose sensation and episodes of fetid rinorrhea, since 7 months. The clinical examination reveal a patient in good shape . Examination of the nasal cavities found some blood clots in the left nasal cavity , the suction...

Purpose: Nasal cavity may contain wide variety of masses within, that differs this organ from the rest of the body. Primary nasal cavity masses consist of 0.2% 0.8% of all malignancies. This paper aims to emphasize the main characteristics of different nasal cavity masses on cross-sectional images which may cause symptoms varying from simple nasal obstruction to metastatic invasion. We tried to...

Basaloid squamous cell carcinoma (BSCC) is often founded in the head and neck region. However, BSCC in the sinonasal tract is rare. We report here on the case of a 58-yr-old woman who presented with nasal obstruction and epistaxis. Computed tomography and examination of the nasal cavity revealed a tumor mass that originated from the right inferior turbinate with erosion of the nasal floor. The ...

Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical and complementary investigation of vascu...

Olfactory neuroblastoma (ON) is a rare type of malignant neoplasm originating from the olfactory neuroepithelial cells of the nasal cavity. ON is also known as esthesioneuroblastoma or neuroendocrine carcinoma. The malignancy accounts for <3% of tumors originating in the nasal cavity. Through the nasal cavity, ON may infiltrate the sinuses, the orbit and the cranium. The tumor is characterized ...

A novel, standardized geometry of the human nasal cavity was created by aligning and processing 30 sets of computed tomography (CT) scans of nasal airways of healthy subjects. Digital three-dimensional (3-D) geometries of the 60 single human nasal cavities (30 right and 30 mirrored left cavities) were generated from the CT scans and measurements of physical parameters of each single nasal cavit...

Transportation and deposition of droplets from a nebulizer within the nasal cavity are dependent on the existing airflow patterns. Figure 1 illustrates the inspired air profile, which is the dominant airflow pattern in the cavity. Inspired air patterns largely determine where and how drug deposition in the nasal cavity occurs. Relatively low flow amounts are observed in the olfactory region (<1...

The nasal passages mainly adjust the temperature and humidity of inhaled air to reach the alveolar condition required in the lungs. By contrast to most other non-human primates, macaque monkeys are distributed widely among tropical, temperate and subarctic regions, and thus some species need to condition the inhaled air in cool and dry ambient atmospheric areas. The internal nasal anatomy is be...
