Otorhinolaryngology is a surgical subspeciality within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians. Patients seek treatment from an otorhinolaryngologist for diseases of the ear, nose, throat, base of the skull, head, and neck. These commonly include functional diseases that affect the senses and activities of eating, drinking, speaking, breathing, swallowing, and hearing. In addition, ENT surgery encompasses the surgical management of cancers and benign tumors and reconstruction of the head and neck as well as plastic surgery of the face, scalp, and neck.
Rhinoplasty, commonly called nose job, medically called nasal reconstruction is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition. Surgery only on the septum is called a septoplasty.
The vomer is one of the unpaired facial bones of the skull. It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. The vomer forms the inferior part of the nasal septum in humans, with the superior part formed by the perpendicular plate of the ethmoid bone. The name is derived from the Latin word for a ploughshare and the shape of the bone.
The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, also known as fossae. Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.
In anatomy, a nasal concha, also called a nasal turbinate or turbinal, is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various animals. The conchae are shaped like an elongated seashell, which gave them their name. A concha is any of the scrolled spongy bones of the nasal passages in vertebrates.
Septoplasty [ˈsɛp.toˌplæ.sti] (Etymology: L, saeptum, septum; Gk, πλάσσειν plassein – to shape), or alternatively submucous septal resection and septal reconstruction, is a corrective surgical procedure done to straighten a deviated nasal septum – the nasal septum being the partition between the two nasal cavities. Ideally, the septum should run down the center of the nose. When it deviates into one of the cavities, it narrows that cavity and impedes airflow. Deviated nasal septum or “crooked” internal nose can occur at childbirth or as the result of an injury or other trauma. If the wall that functions as a separator of both sides of the nose is tilted towards one side at a degree greater than 50%, it might cause difficulty breathing. Often the inferior turbinate on the opposite side enlarges, which is termed compensatory hypertrophy. Deviations of the septum can lead to nasal obstruction. Most surgeries are completed in 60 minutes or less, while the recovery time could be up to several weeks. Put simply, septoplasty is a surgery that helps repair the passageways in the nose making it easier to breathe. This surgery is usually performed on patients with a deviated septum, recurrent rhinitis, or sinus issues.
The nasal septum separates the left and right airways of the nasal cavity, dividing the two nostrils.
Nasal septum deviation is a physical disorder of the nose, involving a displacement of the nasal septum. Some displacement is common, affecting 80% of people, mostly without their knowledge.
A nasal septum perforation is a medical condition in which the nasal septum, the bony/cartilaginous wall dividing the nasal cavities, develops a hole or fissure.
The nasalis muscle is a sphincter-like muscle of the nose. It has a transverse part and an alar part. It compresses the nasal cartilages, and can "flare" the nostrils. It can be used to test the facial nerve (VII), which supplies it.
The dilator naris muscle is a part of the nasalis muscle. It has an anterior and a posterior part. It has origins from the nasal notch of the maxilla and the major alar cartilage, and a single insertion near the margin of the nostril. It controls nostril width, including changes during breathing. Its function can be tested as an analogue for the function of the facial nerve (VII), which supplies it.
Empty nose syndrome (ENS) is a clinical syndrome, the hallmark symptom of which is a sensation of suffocation despite a clear airway. This syndrome is often referred to as a form of secondary atrophic rhinitis. ENS is a potential complication of nasal turbinate surgery or injury. Patients have usually undergone a turbinectomy or other surgical procedures that injure the nasal turbinates.
The major alar cartilage is a thin, flexible plate, situated immediately below the lateral nasal cartilage, and bent upon itself in such a manner as to form the medial wall and lateral wall of the nostril of its own side.
The septal nasal cartilage is composed of hyaline cartilage. It is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front.
The human nose is the most protruding part of the human face. It bears the nostrils and is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum which separates the nostrils and divides the nasal cavity into two.
Nasal septal hematoma is a condition affecting the nasal septum. It can be associated with trauma.
The respiratory system of the horse is the biological system by which a horse circulates air for the purpose of gaseous exchange.
A turbinectomy or turbinoplasty is a surgical procedure, that removes tissue, and sometimes bone, of the turbinates in the nasal passage, particularly the inferior nasal concha. The procedure is usually performed to relieve nasal obstructions. In most cases, turbinate hypertrophy is accompanied by some septum deviation, so the surgery is done along with septoplasty.
Nasal chondrocytes (NC) are present in the hyaline cartilage of the nasal septum and in fact are the only cell type within the tissue. Similar to chondrocytes present in articular cartilage, NC express extracellular matrix proteins such as glycosaminoglycans and collagen.
Nasal surgery is a medical procedure designed to treat various conditions that cause nasal blockages in the upper respiratory tract, for example nasal polyps, inferior turbinate hypertrophy, and chronic rhinosinusitis. It encompasses several types of techniques, including rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, each with its respective postoperative treatments. Furthermore, nasal surgery is also conducted for cosmetic purposes. While there are potential risks and complications associated, the advancement of medical instruments and enhanced surgical skills have helped mitigate them.
