Deviated septum surgery, called septoplasty, is one of the most common ear, nose, and throat procedures and is not considered dangerous. Serious complications are rare, and the risk of death from anesthesia alone is less than 1 in a million for healthy patients having routine procedures. That said, every surgery carries some risk, and septoplasty is no exception. Knowing exactly what those risks look like, how often they occur, and what recovery involves can help you decide whether the benefits outweigh the concerns.
Overall Complication Rates
Septoplasty is an outpatient procedure, meaning most people go home the same day. A large systematic review and meta-analysis of conventional septoplasty found that the rate of septal perforation (a hole forming in the wall between the two sides of the nose) was about 2%, making it one of the more frequently tracked complications. Bleeding, infection, and reactions to anesthesia round out the short list of risks the Mayo Clinic highlights as inherent to the surgery.
Most complications that do occur are minor and resolve on their own or with simple treatment. The procedure has been performed for decades, and surgical techniques have become increasingly refined. For a healthy person without significant underlying conditions, septoplasty sits firmly in the low-risk category.
Bleeding and Pain After Surgery
Some bleeding from the nose is normal in the first few days. Surgeons typically place internal splints or packing inside the nose to support healing and control early bleeding. A light ooze onto gauze placed under the nose is expected. If you’re soaking through that gauze every hour, that crosses into territory where you should contact your surgeon.
Pain is usually manageable with prescribed medication and tends to peak in the first 48 hours. Swelling, congestion, and a feeling of pressure in the nose and face are common for the first week or two. Most people return to desk work within a week, though strenuous activity is typically off-limits for several weeks.
Changes to Smell
Temporary changes to your sense of smell are more common than most people realize. In the first week after surgery, the majority of patients experience significant smell reduction simply because of swelling, crusting, and packing inside the nose. One study found that at one week post-op, roughly a third of patients had reduced smell compared to their baseline, and another found that 87.5% had essentially no sense of smell at all during that first week.
The reassuring part: this almost always resolves. By six months, olfactory function in most studies had returned to preoperative levels. Permanent, surgery-induced smell reduction occurs in roughly 2.7% of cases across studies, and true permanent loss of smell (anosmia) appears in only about 1% to 2%. So while a temporary dip is very common and can feel alarming, lasting damage to smell is uncommon.
Septal Perforation
A septal perforation is a small hole left in the nasal septum after surgery. The meta-analysis of multiple studies placed this risk at approximately 2%. Small perforations often cause no symptoms at all and may never need treatment. Larger ones can produce a whistling sound when breathing, persistent dryness, or crusting inside the nose. If a perforation does cause problems, it can sometimes be repaired with a follow-up procedure, though that adds complexity.
Rare but Serious Complications
The complications that genuinely qualify as dangerous are extremely uncommon. A cerebrospinal fluid (CSF) leak, where the fluid surrounding the brain leaks through a communication between the skull base and the nose, is a recognized but rare risk of nasal surgery. Signs include clear, watery drainage from one side of the nose that worsens when bending over, a salty taste in the back of the throat, or headaches that get worse when sitting upright. If untreated, a CSF leak can lead to meningitis, which is why surgeons monitor for this carefully.
Anesthesia carries its own risks, but for healthy patients undergoing routine outpatient procedures, the Anesthesia Patient Safety Foundation puts the risk of death at less than 1 in a million. That risk increases for people with serious underlying health conditions, but septoplasty patients are generally healthy and the procedure is short.
Empty Nose Syndrome
Empty nose syndrome (ENS) is a condition that gets a lot of attention online, and understandably causes anxiety. It occurs when tissue removal during nasal surgery, particularly from the turbinates (the structures inside your nose that warm and humidify air), changes how your nose senses airflow. People with ENS feel like they can’t get enough air through their nose even though the airway is physically open.
ENS affects less than 1% of people who have turbinate reduction surgery. Septoplasty alone, without significant turbinate work, carries an even lower risk. Interestingly, the amount of tissue removed doesn’t always predict who develops symptoms. One person may have substantial tissue removed with no issues while another develops ENS after a minor reduction. If turbinate reduction is part of your planned procedure, it’s worth discussing with your surgeon how much tissue they intend to remove and what approach they use.
Factors That Increase Your Risk
Certain things can shift septoplasty from very safe to slightly less so. Smoking is the most significant modifiable risk factor. It slows healing, increases the chance of infection, and raises the likelihood of complications during the procedure itself. If you smoke, stopping well before surgery meaningfully reduces your risk.
Blood-thinning medications and common over-the-counter painkillers like aspirin and ibuprofen increase bleeding risk. Your surgeon will ask you to stop these before and after surgery. Be honest about every medication and supplement you take, since some herbal supplements also thin the blood.
Revision septoplasty, where a second surgery is needed because the first didn’t fully resolve the problem or the septum shifted back, can be more complex than the initial procedure. Scar tissue from the first surgery makes the anatomy harder to work with, and there’s less cartilage available to reshape. If you’re facing a revision, the overall risk profile is somewhat higher than for a first-time septoplasty.
Warning Signs During Recovery
Most recovery is uneventful, but certain symptoms after surgery need immediate attention:
- Heavy, uncontrollable nosebleed that doesn’t respond to gentle pressure
- Fever above 102°F or any fever lasting more than two days
- Neck stiffness combined with headache, which can signal meningitis
- Confusion or disorientation
- Severe headache that worsens rather than improves
- Trouble breathing beyond the expected congestion
- Escalating pain that doesn’t respond to prescribed medication
These are uncommon, but recognizing them quickly makes a significant difference in outcomes. Most people recover with nothing more dramatic than a stuffy nose and mild discomfort for a couple of weeks.
