Genioglossus Advancement
Genioglossus advancement (GA) is a surgical procedure or sleep surgery in which the base of the tongue is pulled forward. It is usually to increase airway size due to deformity or a sleep breathing disorder. This procedure is frequently performed with either uvulopalatopharyngoplasty or maxillomandibular advancement Maxillomandibular advancement (MMA) or orthognathic surgery, also sometimes called bimaxillary advancement (Bi-Max), or maxillomandibular osteotomy (MMO), is a surgical procedure or sleep surgery which moves the upper jaw (maxilla) and the lower j ... surgeries. Tongue muscles (genioglossus, geniohyoid and others) are attached to the lower jaw below the teeth. During a genioglossus advancement procedure, a small window or bone cut is made in the front part of the lower jaw (mandible) at the level of the geniotubercle which is where the genioglossus muscle is attached. This piece of bone along with the attachment for the tongue (genial tubercle) is pulled forward and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Procedure
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissue (biology), tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, operating theater, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery.

Sleep Surgery
Sleep surgery is a range of surgical procedures to treat sleep-related breathing disorders (sleep-disordered breathing), especially obstructive sleep apnea (OSA). The spectrum of sleep-related breathing disorders also includes Snoring, primary snoring (non apneic snoring), upper airway resistance syndrome, and obesity hypoventilation syndrome. These surgeries are performed by surgeons trained in otolaryngology, oral maxillofacial surgery, and craniofacial surgery. Background Obstructive sleep apnea (OSA) is defined as either cessation of breathing (apnea) for 10 seconds, or a decrease in normal breathing (hypopnea) with an associated desaturation in oxygen and arousal during sleep that lasts at least 10 seconds. In adults, it is typical to have up to 4.9 events per hour. In OSA, affected individuals are categorized based on how many apneas or hypopneas (apnea-hypopnea index or AHI) or events they have per hour. * Normal: <5 events per hour * Mild: 5 to <15 events per hour * M ...

Tongue
The tongue is a Muscle, muscular organ (anatomy), organ in the mouth of a typical tetrapod. It manipulates food for chewing and swallowing as part of the digestive system, digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is to enable speech in humans and animal communication, vocalization in other animals. The human tongue is divided into two parts, an oral cavity, oral part at the front and a pharynx, pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of connective tissue, fibrous tissue (the lingual septum) that results in a groove, the median sulcus, on the tongue's surface. There are two groups of glossal muscles. The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sleep Apnea
Sleep apnea (sleep apnoea or sleep apnœa in British English) is a sleep-related breathing disorder in which repetitive Apnea, pauses in breathing, periods of shallow breathing, or collapse of the upper airway during sleep results in poor ventilation and sleep disruption. Each pause in breathing can last for a few seconds to a few minutes and often occurs many times a night. A choking or snorting sound may occur as breathing resumes. Common symptoms include daytime sleepiness, snoring, and non restorative sleep despite adequate sleep time. Because the disorder disrupts normal sleep, those affected may experience sleepiness or feel tired during the day. It is often a chronic condition. Sleep apnea may be categorized as obstructive sleep apnea (OSA), in which breathing is interrupted by a blockage of air flow, central sleep apnea (CSA), in which regular unconscious breath simply stops, or a combination of the two. OSA is the most common form. OSA has four key contributors; these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uvulopalatopharyngoplasty
Uvulopalatopharyngoplasty (abbreviated as UPPP or UP3) is a type of sleep surgery, which are surgical procedures for sleep-related breathing disorders, especially obstructive sleep apnea (OSA). Uvulopalatopharyngoplasty involves removal and/or remodeling of tissues in the throat in order to prevent obstruction of the airway during sleep. Tissues which may typically be removed include the paryngeal tonsils and the adenoid tonsil. Tissues which may typically be remodeled include the uvula (see uvulotomy), the soft palate, and parts of the pharynx. UPPP is the most common surgical procedure performed for OSA. Background OSA is one of the most common types of sleep-related breathing disorder. It involves obstruction of the upper airway during sleep. Loud snoring and apnea (periods of no breathing) followed by gasping and choking are signs of the condition. The main treatment is continuous positive airway pressure and a range of other measures such sleeping on the side and mandibular a ...

Maxillomandibular Advancement
Maxillomandibular advancement (MMA) or orthognathic surgery, also sometimes called bimaxillary advancement (Bi-Max), or maxillomandibular osteotomy (MMO), is a surgical procedure or sleep surgery which moves the upper jaw (maxilla) and the lower jaw (mandible) forward. The procedure was first used to correct deformities of the facial skeleton to include malocclusion. In the late 1970s advancement of the lower jaw (mandibular advancement) was noted to improve sleepiness in three patients. Subsequently, maxillomandibular advancement was used for patients with obstructive sleep apnea. Currently, maxillomandibular advancement surgery is often performed simultaneously with genioglossus advancement (tongue advancement). The genioglossus advancement pulls the tongue forward in a manner that decreases the amount of tongue blockage during sleep. MMA has been demonstrated to be one of the most effective surgical treatments for sleep apnea, due to its high success rate. Nonetheless, the pr ...
