Turbinectomy
A turbinectomy or turbinoplasty (preserving the mucosal layer) 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. Indications A turbinectomy is usually performed to resolve turbinate hypertrophy, where the turbinates are swollen and enlarged. Common causes of this condition are allergies, environmental irritants, or a deviated septum. Procedure Traditional methods There are many different techniques used in a turbinectomy, including electrocautery, cryotherapy (cryoturbinectomy), laser vaporization, and turbinoplasty. These require general anesthesia. Radiofrequency ablation The use of radiofrequency ablation has shown to be a safer alternative, being performed as an outpatient procedure, ...

Mucosal Tissue
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive tract ...

Cryotherapy
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy may be used to treat a variety of tissue lesions. The most prominent use of the term refers to the surgical treatment, specifically known as cryosurgery or cryoablation. Cryosurgery is the application of extremely low temperatures to destroy abnormal or diseased tissue and is used most commonly to treat skin conditions. Cryotherapy is used in an effort to relieve muscle pain, sprains and swelling after soft tissue damage or surgery. For decades, it has been commonly used to accelerate recovery in athletes after exercise. Cryotherapy decreases the temperature of tissue surface to minimize hypoxic cell death, edema accumulation, and muscle spasms, all of which ultimately alleviate discomfort and inflammation. It can be a range of treatments from the application of ice packs or immersion in ice baths (generally known as cold therapy), to the use of cold chambe ...

Somnoplasty
Somnoplasty is a trademark by Somnus Medical Technologies used for its radiofrequency ablation medical devices cleared by the Food and Drug Administration (FDA) to treat habitual snoring, chronic nasal obstruction, and obstructive sleep apnea (OSA) to shrink the tissues that are causing obstruction. Somnoplasty is typically an outpatient procedure that takes 30–45 minutes. Procedure Prior to somnoplasty procedure, a doctor may want a patient to attempt more conservative remedies such as sleeping in a different position. Once the Somnoplasty procedure is started, the patient is given a local anesthetic and a special needle-like electrode with an insulating sleeve covering all but the tip, that delivers RF energy under the surface of the tissue. The electrode is used to administer controlled, low-power RF energy to create coagulative (clotting) lesions, where tissue is denatured, beneath the mucosa (lining) of the targeted areas: * For chronic nasal obstruction, the turbinates are ...

Nasal Obstruction
Nasal congestion is the blockage of nasal breathing usually due to membranes lining the nose becoming swollen from inflamed blood vessels. Background In about 85% of cases, nasal congestion leads to mouth breathing rather than nasal breathing. According to Jason Turowski, MD of the Cleveland Clinic, "we are designed to breathe through our noses from birth—it's the way humans have evolved." This is referred to as "obligate nasal breathing." Nasal congestion can interfere with hearing and speech. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea or upper airway resistance syndrome. In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea with insufficient oxygen levels and hypoxia. The problem usually resolves after surgery to remove the adenoids and tonsils, however the problem often relapses later in life due to craniofacial alterations from chronic nasal congestion. Causes * Allergies, like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasal Concha
In anatomy, a nasal concha (), plural conchae (), 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 (Latin ''concha'' from Greek ''κόγχη''). A concha is any of the scrolled spongy bones of the nasal passages in vertebrates.''Anatomy of the Human Body'' Gray, Henry (1918) The Nasal Cavity. In humans, the conchae divide the nasal airway into four groove-like air passages, and are responsible for forcing inhaled air to flow in a steady, regular pattern around the largest possible of |
Atrophic Rhinitis
Chronic atrophic rhinitis, or simply atrophic rhinitis, is a chronic inflammation of the nose characterised by atrophy of nasal mucosa, including the glands, turbinate bones and the nerve elements supplying the nose. Chronic atrophic rhinitis may be primary and secondary. Special forms of chronic atrophic rhinitis are rhinitis sicca anterior and ozaena. It can also be described as the empty nose syndrome. Signs and symptoms * It is most commonly seen in females. * It is reported among patients from lower socioeconomic groups. * The nasal cavities become roomy and are filled with foul smelling crusts which are black or dark green and dry, making expiration painful and difficult. * Microorganisms are known to multiply and produce a foul smell from the nose, though the patients may not be aware of this, because the nerve endings (responsible for the perception of smell) have become atrophied. This is called merciful anosmia. * Patients usually complain of nasal obstruction despit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinorrhea
Rhinorrhea, rhinorrhoea, or informally runny nose is the free discharge of a thin mucus fluid from the nose; it is a common condition. It is a common symptom of allergies ( hay fever) or certain viral infections, such as the common cold or COVID-19. It can be a side effect of crying, exposure to cold temperatures, cocaine abuse, or drug withdrawal, such as from methadone or other opioids. Treatment for rhinorrhea is not usually undertaken, but there are a number of medical treatments and preventive techniques. The term was coined in 1866 from the Ancient Greek, Greek ''rhino-'' ("of the nose") and ''-rhoia'' ("discharge" or "flow"). Signs and symptoms Rhinorrhea is characterized by an excess amount of mucus produced by the mucous membranes that line the nasal cavities. The membranes create mucus faster than it can be processed, causing a backup of mucus in the nasal cavities. As the cavity fills up, it blocks off the air passageway, causing difficulty breathing through the nose. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epithelium
Epithelium or epithelial tissue is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. It is a thin, continuous, protective layer of compactly packed cells with a little intercellular matrix. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin. There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal. These can be arranged in a singular layer of cells as simple epithelium, either squamous, columnar, or cuboidal, or in layers of two or more cells deep as stratified (layered), or ''compound'', either squamous, columnar or cuboidal. In some tissues, a layer of columnar cells may appear to be stratified due to the placement of the nuclei. This sort of tissue is called pseudostratified. All glands are made up of epithe ...

Local Anesthesia
Local anesthesia is any technique to induce the absence of sensation in a specific part of the body, generally for the aim of inducing local analgesia, that is, local insensitivity to pain, although other local senses may be affected as well. It allows patients to undergo surgical and dental procedures with reduced pain and distress. In many situations, such as cesarean section, it is safer and therefore superior to general anesthesia. The following terms are often used interchangeably: * ''Local anesthesia'', in a strict sense, is anesthesia of a small part of the body such as a tooth or an area of skin. * ''Regional anesthesia'' is aimed at anesthetizing a larger part of the body such as a leg or arm. * ''Conduction anesthesia'' encompasses a great variety of local and regional anesthetic techniques. Medical A local anesthetic is a drug that causes reversible local anesthesia and a loss of nociception. When it is used on specific nerve pathways (nerve block), effects such as ...

Lidocaine
Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type. It is also used to treat ventricular tachycardia. When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours. Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area. It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding. If injected intravenously, it may cause cerebral effects such as confusion, changes in vision, numbness, tingling, and vomiting. It can cause low blood pressure and an irregular heart rate. There are concerns that injecting it into a joint can cause problems with the cartilage. It appears to be generally safe for use in pregnancy. A lower dose may be required in those with liver problems. It is generally safe to use in those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outpatient Procedure
A patient is any recipient of health care services that are performed by Health professional, healthcare professionals. The patient is most often Disease, ill or Major trauma, injured and in need of therapy, treatment by a physician, nurse, optometrist, dentist, veterinarian, or other health care provider. Etymology The word wikt:patient, patient originally meant 'one who suffers'. This English noun comes from the Latin word ', the present participle of the deponent verb, ', meaning 'I am suffering,' and akin to the Ancient Greek, Greek verb (', to suffer) and its cognate noun (). This language has been construed as meaning that the role of patients is to passively accept and tolerate the suffering and treatments prescribed by the healthcare providers, without engaging in Shared decision-making in medicine, shared decision-making about their care.

Radiofrequency Ablation
Radiofrequency ablation (RFA), also called fulguration, is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz). RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia. When it is delivered via catheter, it is called radiofrequency catheter ablation. Two important advantages of radio frequency current (over previously used low frequency AC or pulses of DC) are that it does not directly stimulate nerves or heart muscle and therefore can often be used without the need for general anesthesia, and that it is very specific for treating the desired tissue without significant collateral damage; due to this, it is gaining in popularity as an alternative for eligible patients who do not want to undergo surgery. Documented benefits have led to RFA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
