Obstructive sleep apnea (OSA) is a sleep disorder in which the airway repeatedly narrows or closes during sleep, interrupting breathing and fragmenting rest. It is diagnosed by a physician through a sleep study, and most people start with non-surgical treatment such as positive airway pressure (PAP) therapy. Surgery becomes part of the conversation mainly for adults who cannot tolerate or will not use PAP, and oral and maxillofacial surgeons are one of the surgical specialties involved, alongside ear, nose, and throat (ENT) surgeons.
At Legacy Oral Surgery & Implants, we want patients to understand how sleep apnea care is organized so they can ask informed questions. Sleep apnea surgery is not one of the procedures listed on our oral surgery services page, so this guide is educational: it explains how a diagnosis is made, what comes before surgery, and which four surgical approaches sleep surgeons commonly discuss. Your sleep physician is the right starting point for any treatment decision, and if you have questions about the oral surgery care we do provide, you can contact us online.
How Sleep Apnea Affects Your Health
In obstructive sleep apnea, the soft tissues at the back of the throat, including the soft palate, uvula, tonsils, and tongue, relax and collapse during sleep, partially or fully blocking the airway. Each blockage can cause a brief arousal from sleep, often without the person noticing, and these events can repeat many times per hour.
The effects extend beyond daytime fatigue. Untreated OSA is associated with an increased risk of high blood pressure, heart rhythm problems, stroke, and type 2 diabetes. Loud snoring, gasping during sleep, morning headaches, and excessive daytime sleepiness are common warning signs. If you notice these symptoms, talk with your primary care physician about whether a sleep evaluation is appropriate.
How Sleep Apnea Is Diagnosed
Sleep apnea is diagnosed by a physician, often a board-certified sleep medicine specialist, using a sleep study. This may be an overnight study in a sleep lab or, for some adults, a home sleep apnea test. The study measures how often breathing pauses or becomes shallow, reported as the apnea-hypopnea index (AHI), which is the number of events per hour of sleep.
Severity is commonly described using AHI ranges: mild (5 to 15 events per hour), moderate (15 to 30), and severe (30 or more). The diagnosis, the severity, and your other health conditions guide every later decision, including whether surgery should ever be considered. No surgical evaluation should take the place of this medical diagnosis.
Treatments That Usually Come Before Surgery
PAP therapy, most often CPAP, is the standard first-line treatment for many adults with OSA. It uses gentle air pressure through a mask to keep the airway open during sleep. When used consistently, it is highly effective, but many people find the mask difficult to tolerate.
For some patients, oral appliance therapy is an alternative. A custom mandibular advancement device, fitted by a dentist trained in dental sleep medicine, holds the lower jaw slightly forward during sleep. Clinical guidance from the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine supports oral appliances for adults who prefer them or cannot tolerate CPAP. Weight management, positional therapy, and treating nasal obstruction can also help, depending on the cause.
When Surgery Enters the Conversation
The American Academy of Sleep Medicine’s 2021 clinical practice guideline on surgical referral recommends that clinicians discuss referral to a sleep surgeon with adults who have OSA, a body mass index under 40, and who are intolerant of or unwilling to use PAP. For adults with class II or III obesity who cannot use PAP, the guideline recommends discussing referral to a bariatric surgeon. Surgery is therefore usually a second step, chosen after a physician has confirmed the diagnosis and first-line options have been tried or ruled out.
Before any procedure, a sleep surgeon examines where the airway is collapsing. This can involve a physical exam, imaging of the jaws and airway, and sometimes an endoscopic evaluation of the airway under sedation. Because collapse often happens at more than one level, surgical plans are frequently tailored and may combine procedures.
Four Surgical Approaches Sleep Surgeons Commonly Discuss
The procedures below are performed by sleep surgeons with the relevant training. Oral and maxillofacial surgeons most often perform the jaw-based procedures, while ENT surgeons most often perform the soft tissue and throat procedures. Your sleep physician can refer you to the appropriate surgeon if one of these approaches may suit you.
Uvulopalatopharyngoplasty (UPPP)
UPPP removes or reshapes excess soft tissue at the back of the throat, which can include part of the uvula, part of the soft palate, and the tonsils if they are still present. By widening the airway at the level of the palate, it reduces the tissue available to collapse during sleep. UPPP is usually performed by an ENT surgeon under general anesthesia, and recovery involves significant throat soreness and a soft diet for a week or more. It tends to work best when the obstruction is mainly at the level of the soft palate.
Genioglossus Advancement (GA)
The genioglossus is the large muscle that makes up much of the tongue and attaches to the inside of the lower jaw near the chin. In genioglossus advancement, the surgeon moves a small segment of the jawbone where this muscle attaches slightly forward, which pulls the base of the tongue forward and helps keep it from falling back into the airway. GA is usually part of a multilevel plan rather than a standalone procedure and may be performed by an oral and maxillofacial surgeon or an ENT surgeon.
Maxillomandibular Advancement (MMA)
MMA moves both the upper jaw (maxilla) and lower jaw (mandible) forward, which enlarges the airway behind the palate and tongue at the same time. It is one of the most studied surgical options for OSA and is performed by oral and maxillofacial surgeons, typically in a hospital. A 2016 meta-analysis in JAMA Otolaryngology pooling 518 patients reported surgical success, defined as at least a 50% drop in AHI to under 20 events per hour, in 85.5% of patients with AHI data, and a cure, defined as an AHI under 5, in 38.5%. Recovery takes several weeks, with a modified diet while the jaws heal, and MMA can change facial appearance, which is part of the pre-surgical discussion.
Hyoid Suspension
The hyoid is a small U-shaped bone in the neck that anchors muscles of the tongue and throat. Hyoid suspension repositions this bone forward, usually securing it to the thyroid cartilage or the jaw, to stabilize the tongue base and lower throat. It is typically performed by ENT surgeons and is almost always one part of a multilevel plan, often alongside genioglossus advancement.
Questions to Bring to Your Sleep Physician
If PAP has not worked for you, a structured conversation with your sleep physician can clarify your next step. Useful questions include how severe your sleep apnea is, where your airway appears to be collapsing, whether an oral appliance is worth trying, and whether your body mass index and health history make you a candidate for surgical referral.
It also helps to ask which type of sleep surgeon your physician recommends for your anatomy, what success means for the procedure being discussed, and whether a follow-up sleep study will be done afterward to measure the result. Teeth grinding often appears alongside sleep-disordered breathing, and our article on how bruxism and sleep disorders are related explains that connection. If corrective jaw surgery has come up for bite or facial reasons as well, our post on when jaw surgery is medically necessary covers the general distinctions.
Frequently Asked Questions About Sleep Apnea Surgery
Who is a candidate for sleep apnea surgery?
Candidates are usually adults whose obstructive sleep apnea has been confirmed by a sleep study and who cannot tolerate or will not use PAP therapy. Current American Academy of Sleep Medicine guidance recommends discussing referral to a sleep surgeon for these adults when their body mass index is under 40. The location and severity of airway collapse, overall health, and personal preferences all shape which procedure, if any, is appropriate.
Does sleep apnea surgery cure the condition?
Not always. Surgery often reduces the number of breathing events substantially, but a full cure is less common. In a 2016 meta-analysis of maxillomandibular advancement, about 85 percent of patients met the study definition of surgical success, while about 39 percent reached an AHI under 5. A follow-up sleep study after surgery is the way to measure your result, and weight changes can affect it over time.
Who diagnoses sleep apnea, a dentist or a doctor?
Sleep apnea is diagnosed by a physician, often a sleep medicine specialist, using an in-lab sleep study or a home sleep apnea test. Dentists and oral surgeons may notice warning signs such as a narrow airway, a large tongue, or signs of teeth grinding and suggest an evaluation, but they do not make the diagnosis. Treatment decisions start with that medical diagnosis.
Can more than one sleep apnea procedure be done at the same time?
Yes. Multilevel surgery, in which two or more procedures are combined, is common when the airway collapses at more than one point. For example, genioglossus advancement is often paired with hyoid suspension or with palate surgery. Your sleep surgeon will explain the tradeoffs for anesthesia, recovery, and expected results before recommending a combined plan.
How do I get started if CPAP is not working for me?
Start with the physician who manages your sleep apnea. Tell them what has made PAP difficult, since mask fit and pressure settings can sometimes be adjusted. Ask whether an oral appliance is worth trying and whether you meet the criteria for referral to a sleep surgeon. Bring your most recent sleep study results to any surgical consultation.
