Hyoid suspension, also known as hyoid myotomy and suspension or hyoid advancement, is a surgical procedure or sleep surgery in which the hyoid bone and its muscle attachments to the tongue and airway are pulled forward with the aim of increasing airway size and improving airway stability in the retrolingual and hypopharyngeal airway (airway behind and below the base of tongue).
Hyoid suspension, also known as hyoid myotomy and suspension or hyoid advancement, is a surgical procedure in which the hyoid bone and its muscle attachments to the tongue and airway are pulled forward in order to increase airway size and improve airway stability behind and below the base of tongue (retrolingual and hypopharyngeal region).
The hyoid bone fracture is a very rare fracture of the hyoid bone, accounting for 0.002% of all fractures in humans. It is commonly associated with strangulation and rarely occurs in isolation. The fracture may be associated with gunshot injury, car accidents or induced vomiting. In 50% of strangulations and 27% of hangings, hyoid fractures occur.
The first involves surgery of the soft tissue (tonsillectomy, uvulopalatopharyngoplasty) and the second involves skeletal surgeries (maxillomandibular advancement). First, Phase 1 or soft tissue surgery is performed and after re-testing with a new sleep study, if there is residual sleep apnea, then Phase 2 surgery would consist of jaw surgery.
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 ...
The body of the hyoid bone is the central part of the hyoid bone. [clarification needed]At the front, the body is convex and directed forward and upward. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.
Surgery is not considered a first line treatment for obstructive sleep apnea in adults. There are prospective, randomized, comparative clinical trials, [ 135 ] and also a systematic Meta-analysis, [ 120 ] showing evidence that conservative uvulopalatopharyngoplasty (UPPP) with or without tonsillectomy is effective in selected patients failing ...
Evidence is accumulating to support the use of oral devices in the treatment of OSA, and studies demonstrating their efficacy [3] have been underpinned by increasing recognition of the importance of upper airway anatomy in the pathophysiology of OSA. [4] Oral devices have been shown to have beneficial effects relating to several areas.
