Uvulopalatopharyngoplasty (UPPP): A Surgical Approach to Sleep Apnea
Updated: 3 days ago
Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 17, 2026
Uvulopalatopharyngoplasty (UPPP) is a common surgery that treats obstructive sleep apnea (OSA) by widening the airway. The surgeon removes or reshapes tissue in the back of the throat, such as the uvula, tonsils and part of the soft palate [1]. It is usually considered when conservative treatments such as CPAP have not helped, and the best results are seen in people who are good candidates based on their anatomy and weight [1].
Quick Answer: What is uvulopalatopharyngoplasty (UPPP)?
Uvulopalatopharyngoplasty (UPPP) is a surgery that treats obstructive sleep apnea by removing or restructuring tissue in the throat, sometimes including the soft palate, uvula and tonsils, to open the airway. It may be recommended when CPAP and weight loss have not worked [1]. UPPP eliminates sleep apnea entirely in some people, while others improve but still need CPAP [1].
What the research says
The benefit tends to fade over time. A meta-analysis of 11 studies with at least 34 months of follow-up found that UPPP and its modifications lowered the apnea-hypopnea index by 15.4 events per hour (46.1%), but the surgical response fell from 67.3% in the short term (3-12 months) to 44.35% in the long term; baseline body mass index and oxygen levels during sleep were linked to the long-term surgical response (He et al., Otolaryngology-Head and Neck Surgery, 2019) [2].
Palate surgery can reduce snoring and daytime sleepiness. A meta-analysis of 55 studies (1,815 adults) found that palatopharyngeal surgery without tonsillectomy reduced the Epworth Sleepiness Scale score by a mean of 3.3 points (95% CI 2.7-3.9) and snoring intensity by 4.1 points (95% CI 3.7-4.6), with considerable differences between studies (Tschopp et al., The Laryngoscope, 2026) [3].
Sleep surgery may also lower blood pressure. In a meta-analysis of 26 studies (1,218 adults with OSA), sleep surgery reduced the apnea-hypopnea index by 26.2 events per hour and lowered office blood pressure by 5.6 mmHg (systolic) and 3.9 mmHg (diastolic), with larger blood pressure reductions in people whose OSA improved more (Kang et al., Sleep Medicine Reviews, 2022) [4].
Who Is a Good Candidate for UPPP?
UPPP may be an option if conservative therapies for OSA have not worked. First-line treatments include devices that open your airway, such as a CPAP machine, and weight loss [1]. UPPP can help if the tissue that collapses at night is in the back of your throat. You may need different or additional surgeries if you have structural problems in your nasal cavity, farther down your throat or elsewhere.
UPPP was not as successful when it was first performed in 1981, and symptoms often improved only to return gradually [1]. Results improved once healthcare providers began using a staging system to identify the best candidates [1]. Providers consider:
The size of your tonsils
The position of your soft palate in relation to your tongue
Your body mass index (BMI)
Based on these characteristics, potential candidates are classified into Stages 1, 2 or 3 [1].
Stage | What to Expect |
Stage 1 | Most likely to improve after UPPP. About 80.6% of people in this stage experience symptom improvement [1]. |
Stage 2 | Less likely to benefit from UPPP |
Stage 3 | Less likely to benefit from UPPP |
Ask your healthcare provider which factors apply to you and whether you are a good candidate for this surgery.
How to Prepare for UPPP Surgery
Your healthcare provider will review the steps to take before surgery. In general, you can expect to:
Review your medical history with your provider, including past procedures, reactions to anesthesia, pregnancy, and any medicines or supplements you take
Stop using tobacco products, including smoking, e-cigarettes and chewing tobacco, because tobacco slows healing [1]
Follow fasting and medicine instructions on when to stop eating or drinking and which medicines to take or avoid
Arrange a ride home and help afterward. If possible, have a loved one care for you for at least 24 hours after discharge [1]
Bring your CPAP machine if you use one, and follow your provider's instructions about using it before the procedure
Tell your provider if you get sick, since surgery may need to be postponed [1]
The UPPP Procedure
UPPP is performed under general anesthesia, so you are asleep for the entire surgery [1]. It may take up to two hours, depending on which structures are removed or reshaped and whether you need additional procedures. During surgery:
You receive a sedative to help you relax and anesthesia to put you to sleep.
Your surgeon props your mouth open and stabilizes your tongue to reach the tissue in the back of your throat, and positions your head and neck so your airway is clear.
Your surgeon marks the tissue to be removed [1].
Your surgeon removes all or part of your tonsils, uvula and possibly some of your soft palate, using a sharp instrument or electrocautery, which uses heat to make cuts in tissue [1].
The wounds are closed with sutures, which may be dissolvable [1].
After surgery, you may be discharged the same day or stay in the hospital for one night [1]. Your care team monitors your vital signs, and you can go home once your breathing has stabilized and you can swallow safely [1]. Your provider will prescribe pain medicine to take at home.
Benefits and Success Rates
UPPP can help you breathe more easily so you can sleep at night. It can help you manage obstructive sleep apnea and reduce related symptoms such as excessive snoring [1]. It is most successful when it is performed on people who are good candidates, and about 80.6% of people in Stage 1 experience symptom improvement [1].
UPPP eliminates sleep apnea entirely in some people. For others, symptoms improve but they still need to use a CPAP machine [1]. Your response depends on your anatomy and other factors, so discuss your expected results with your provider.
Risks and Potential Complications
All surgeries come with risks such as infection and bleeding, and you may have a reaction to anesthesia [1]. Complications specific to UPPP include:
Nasopharyngeal stenosis: Scar tissue builds up and narrows the airway, which may make your throat feel tight, dry or as if something is stuck. This is a rare complication that may require additional surgery to correct [1].
Velopharyngeal insufficiency: The soft palate and throat do not coordinate to close when they should, so liquid may travel up through your nose when you drink. After UPPP this is usually temporary [1].
Changes in your voice: Your voice may sound more high-pitched or nasal for a short time. If your entire uvula is removed, you will not be able to make uvular consonants, which are used in languages such as Danish, French, German, Hebrew and Swedish [1].
Recovery and Dietary Guidelines
Recovery may take two to four weeks or even longer, depending on how extensive your surgery was [1]. Most people need time off from work or school [1]. Follow your provider's instructions, including when it is safe to use CPAP after surgery if you continue to use it.
Timeframe | What to Expect |
Weeks 1 and 2 | Avoid strenuous activity, but stay in motion to help prevent blood clots [1]. Ask your provider which activities to avoid and which can aid recovery |
Weeks 1, 2 and 3 | Start with clear liquids, then advance to soft foods when you are comfortable. Avoid spicy, acidic, hard or crunchy foods that could irritate your mouth, and choose foods and drinks that are cold or at room temperature [1] |
Up to a month | Your throat will be sore, especially when talking or swallowing [1]. Your provider will prescribe pain medicine to help |
Long-Term Outlook
For many people, UPPP improves breathing and sleep quality. Because the effect on sleep apnea can decrease over time and body weight influences long-term results [2], following your post-operative care instructions and discussing your goals with your provider matter. Ask your provider about expected outcomes based on your diagnosis, including whether you will need to keep using a CPAP machine.
When to Call Your Doctor
Contact your healthcare provider if UPPP does not improve your symptoms or if you notice signs of a complication, such as:
Worsening sleep apnea symptoms
Blood in your saliva
Food getting stuck in your throat or trouble swallowing
Signs of infection, such as fever, redness, swelling or pus [1]
See a healthcare provider immediately or go to the emergency room if you have bleeding [1].
Conclusion
UPPP is a common surgical option for people whose obstructive sleep apnea has not improved with conservative treatment. By carefully selecting candidates through staging, providers can improve the chances of a good result. It can eliminate sleep apnea in some people and improve symptoms in others, though some people still need CPAP and the benefit can fade over time. If you are considering UPPP, talk with your provider about whether you are a good candidate, what recovery involves, and what outcome to expect.
Frequently Asked Questions
What is the main goal of UPPP surgery?
The goal is to widen the airway by removing or reshaping tissue in the throat that blocks breathing during sleep, which can reduce the airway collapse behind obstructive sleep apnea.
How long does the UPPP procedure take?
Surgery may take up to two hours, depending on which structures are removed or reshaped and whether additional procedures are needed to address other structural issues.
Will I need to stay in the hospital overnight?
You may be discharged the same day or stay for one night. You can go home once your breathing has stabilized and you can swallow safely.
Can UPPP cure my snoring?
UPPP can reduce snoring and other symptoms of obstructive sleep apnea, but results vary from person to person and depend on your anatomy and weight. Ask your provider what to expect for you.
When can I return to work after UPPP?
Recovery may take two to four weeks or longer, depending on how extensive the surgery was. Most people take time off from work or school while they heal.
What should I eat after surgery?
Start with clear liquids, then advance to soft foods as you feel comfortable. Avoid spicy, acidic, hard or crunchy foods, and choose foods and drinks that are cold or at room temperature.
Is UPPP a permanent solution for sleep apnea?
For some people the benefit lasts, but studies show the effect on sleep apnea can fade over time, and body weight influences long-term results. Discuss expected outcomes with your provider.
What happens if my uvula is removed?
Your voice may sound higher-pitched or nasal for a short time. If the whole uvula is removed, you will not be able to make the uvular consonants used in languages such as French, German, Danish, Hebrew and Swedish.
Does UPPP replace the need for a CPAP machine?
For some people it eliminates sleep apnea entirely. Others improve but still need CPAP, so ask your provider whether you will keep using it and when it is safe to restart after surgery.
What are the signs of a complication after surgery?
Call your provider for worsening sleep apnea symptoms, blood in your saliva, food getting stuck or trouble swallowing, or signs of infection such as fever, redness, swelling or pus. See a provider immediately or go to the ER if you have bleeding.
