Snoring Treatment in Gangnam, Seoul
Medically reviewed by Dr. Kim Yoo Suk, MD · Board-certified otolaryngologist · Former professor, Yonsei & Ajou University · Consultations in English
QUICK ANSWER
Snoring is the sound of soft tissues in the throat and nose vibrating as air passes through a narrowed airway during sleep. It is common and often harmless, but loud nightly snoring with pauses in breathing may signal obstructive sleep apnea. An ENT evaluation finds where the airway narrows so treatment can target the nose, throat or tongue base.
What is snoring?
Snoring is noise produced by vibration of the soft palate, uvula, tonsils, tongue base or nasal tissues when airflow becomes turbulent in a partly collapsed upper airway. During sleep, the muscles that hold the airway open relax, so any narrowing that is tolerated during the day becomes noisy at night.
Simple (primary) snoring occurs without significant breathing interruptions. When the airway repeatedly closes, the condition becomes obstructive sleep apnea.
Symptoms and signs
- Loud snoring reported by a partner or roommate
- Witnessed pauses, gasping or choking during sleep
- Waking unrefreshed, morning headache or dry mouth
- Daytime sleepiness and poor concentration
- Waking to urinate several times a night
Causes and risk factors
- Nasal obstruction from a deviated septum, enlarged turbinates, polyps or rhinitis
- Large tonsils, a long soft palate or a bulky tongue base
- Weight gain, especially around the neck
- Alcohol and sedatives before bed
- Sleeping on the back
- In children, enlarged adenoids and tonsils
How it is diagnosed at our Gangnam clinic
Snoring is evaluated as a whole-airway problem. Dr. Kim examines the nose with nasal endoscopy and the throat and larynx with laryngoscopy to identify narrow points. A cephalogram (airway X-ray) measures jaw position and airway space, and a CT scan may be used for nasal anatomy. If apnea is suspected, a sleep study (polysomnography) records breathing, oxygen levels and sleep stages overnight. This step matters because treating the noise without recognizing apnea can leave a health risk unaddressed.
Treatment options
Lifestyle measures
- Weight reduction where appropriate
- Avoiding alcohol for several hours before sleep
- Side-sleeping positional strategies
- Treating nasal allergy and congestion
Devices
Oral appliances that move the lower jaw forward, and CPAP for those with apnea, are described on our CPAP and oral appliance page.
Surgery when indicated
If a specific obstruction is found, snoring surgery may target it, for example septoplasty or turbinate reduction for the nose, palate or tonsil surgery for the throat, or radiofrequency tongue base reduction. Surgery is chosen to match the site of narrowing, not offered as a one-size-fits-all fix. Nasal procedures are done under local anesthesia at our clinic, and most patients go home the same day.
Many people combine approaches, for example treating nasal allergy, losing some weight and using a positional aid, before deciding whether a procedure is worthwhile. A follow-up review after a few months shows what has helped.
When to see an ENT
Book an evaluation if snoring is loud and nightly, if someone has seen you stop breathing, or if you feel sleepy while driving or working. These signs warrant testing for sleep apnea, which is linked to high blood pressure and cardiovascular disease.

Frequently asked questions
Is snoring dangerous?
Simple snoring is mainly a social problem, but loud snoring with breathing pauses, gasping or daytime sleepiness can indicate obstructive sleep apnea, which affects heart and metabolic health. An ENT evaluation and, if needed, a sleep study can tell the difference.
Can nasal surgery stop snoring?
If the nose is a major source of obstruction, septoplasty or turbinate reduction can improve breathing and reduce snoring. However, snoring often comes from the throat as well, so nasal surgery alone may not eliminate it. Dr. Kim assesses the whole airway first.
Do anti-snoring nasal strips work?
Nasal strips widen the nasal valve slightly and may help some people whose snoring is driven by nasal narrowing. They do not address throat collapse or sleep apnea. They are harmless to try, but persistent loud snoring deserves a proper assessment.
