Septoplasty in Seoul: Straightening a Deviated Septum
The short answer
Septoplasty straightens a bent nasal septum, the wall between your nostrils, from inside the nose so air can flow freely through both sides. In Seoul it typically costs about KRW 2–4 million for international patients, takes 30–90 minutes, and leaves no visible scar. Internal splints usually come out after 5–7 days, and breathing typically improves noticeably once healing settles over 1–3 months.
Key facts
- What it treats: A deviated septum causing blockage, snoring or sinus trouble
- Typical cost in Seoul: About KRW 2–4 million (self-pay)
- Procedure time: About 30–90 minutes
- Anesthesia: General or deep sedation
- Visible scar: None, all incisions are inside
- Splints out: About 5–7 days
- Outside nose shape: Usually unchanged
What a deviated septum does
Your septum is a thin plate of cartilage at the front and bone further back, covered on both sides by a lining called the mucoperichondrium. When it bends to one side, whether from birth or after an injury, it narrows one airway. You may breathe mostly through one nostril, snore, get frequent sinus infections, have trouble with CPAP masks or feel congested all the time.
In septoplasty the surgeon works entirely inside the nose. The lining is gently lifted off the septum, the bent cartilage and bone are trimmed, repositioned or straightened, and a strong L-shaped strip of cartilage is kept along the bridge and front of the septum to support your nose. The lining is then laid back and held flat with soft splints or quilting stitches while it heals.
Most often chosen for and combined with
- Persistent one-sided nasal blockage
- Snoring or mouth breathing linked to the septum
- Recurring sinusitis where the septum blocks drainage
- Harvesting septal cartilage for a cosmetic rhinoplasty
Septoplasty is often combined with turbinate reduction, sinus surgery or a cosmetic rhinoplasty. If the outside of the nose is also crooked, see functional rhinoplasty.
The procedure, step by step
Inside incision
A small cut is made in the lining on one side of the septum, just inside the nostril.
Straighten and preserve
The deviated parts are removed or reshaped. The surgeon preserves at least about 1 cm of cartilage along the bridge and the front so the nose does not lose support.
Where the incisions are made
Only inside the nose. Nothing is visible from the outside, and the shape of your nose normally does not change.
Recovery timeline
| When | What to expect |
|---|---|
| Days 1–3 | Blocked nose, mild bleeding, breathing through the mouth |
| Days 5–7 | Splints removed; air flow improves quickly |
| Weeks 2–4 | Crusting clears with saline rinses |
| Months 1–3 | Lining fully healed; breathing benefit settles |
Avoid blowing your nose hard, heavy lifting and flying for the first week unless your surgeon says otherwise.
Is it right for you?
A good fit if you
- Have a confirmed deviation on examination or CT scan
- Have tried nasal sprays without lasting relief
- Want better breathing without changing your nose's look
Another option may suit you better if
- Your blockage comes mainly from allergies or swollen turbinates
- The nasal valve collapses when you breathe in, which needs grafts
Risks to discuss at your consultation
Ask about bleeding, infection, a septal perforation (a small hole), numbness of the front teeth, persistent blockage and, if too much support is removed, a dip in the bridge. Ask whether a CT scan or endoscopy will be done to confirm the cause first.
Septoplasty cost in Seoul
International patients usually pay about KRW 2–4 million out of pocket. Korean national health insurance may apply to residents for functional septoplasty, so ask the clinic how foreign residents are billed. Adding cosmetic work increases the cost.
Septoplasty vs. functional rhinoplasty
| Septoplasty | Functional rhinoplasty | |
|---|---|---|
| Area treated | Septum only | Septum, valves, turbinates, outer shape |
| Outside scar | None | Often small columella scar |
| Changes appearance | No | Can |
| Typical cost | KRW 2–4 million | KRW 6–12 million |

Patient questions
Frequently asked questions
Will septoplasty change the shape of my nose?
No, septoplasty on its own works inside the nose and normally leaves the outside shape unchanged.
Does septoplasty stop snoring?
It can reduce snoring caused by nasal blockage, but snoring from the throat or sleep apnea may need other treatment.
Is nasal packing used?
Many Seoul clinics now use soft splints or stitches instead of traditional packing, which is more comfortable.
When can I fly after septoplasty?
Usually after the splints are removed and checked, at around 7 days.
Is septoplasty covered by insurance in Korea?
Residents enrolled in Korean national health insurance may be covered for functional cases. Short-term visitors generally pay privately.
