Septoplasty is a surgical procedure designed to correct a deviated nasal septum—the central cartilage and bone partition that separates the two nasal cavities.
What is a deviated septum?
A deviated septum refers to an anatomical variation where the nasal septum—the cartilage and bone dividing the nasal cavity into two passages—is displaced off the midline, creating asymmetry in the nostrils. Although many individuals are born with some degree of septal deviation, it can also result from trauma such as sports injuries, falls, or aggressive nose-blowing. In mild cases, a deviated septum may remain asymptomatic and go unnoticed, but as the deviation increases in severity, it can impede airflow on one or both sides, leading to chronic nasal congestion, difficulty breathing, and a predisposition to sinus infections. In addition, sufferers may experience frequent nosebleeds due to turbulent airflow drying the nasal lining, headaches or facial pain from pressure imbalances, and snoring or sleep disturbances when nighttime breathing is compromised. Diagnosis typically involves a physical examination with a nasal speculum or endoscope, and sometimes imaging studies to assess the extent of deviation and rule out other pathologies. While medical management—such as nasal corticosteroids, decongestants, or antihistamines—can alleviate secondary inflammation, only surgical correction through septoplasty can directly reposition or remove the deviated portions of cartilage and bone. By realigning the septum, septoplasty restores balanced airflow, reduces nasal resistance, and often improves overall nasal function and quality of life.
What is septoplasty?
Septoplasty is a surgical procedure designed to correct a deviated nasal septum, the central cartilage-and-bone partition dividing the nasal cavity into two passages. Though mild septal deviations are common and often asymptomatic, displacement can block airflow, leading to chronic congestion, sinus infections, snoring. During septoplasty, an otolaryngologist uses endoscopic or open techniques to access the septum through incisions inside the nostrils. The surgeon then repositions, trims, or removes the bent or obstructing portions of cartilage and bone, taking care to preserve mucosal lining and support structures essential for nasal function. By straightening the septum and ensuring it is properly anchored to neighboring bones, the procedure restores balanced airflow, reduces nasal resistance, and improves sinus drainage. Septoplasty is usually performed under local or general anesthesia in an outpatient setting, with most patients returning to normal activities within a week. Postoperative care—saline irrigations, head elevation, and avoidance of strenuous activities—minimizes swelling and promotes mucosal healing. While transient swelling, mild discomfort, and crusting are common, serious complications are rare when the surgery is performed by an experienced specialist.
What happens during septoplasty?
During septoplasty, patients first receive general anesthesia or sedation with local anesthesia to ensure comfort and pain control throughout the procedure. The surgeon begins by applying a topical decongestant and anesthetic spray to shrink the nasal lining and improve visualization. Using small endoscopic instruments or traditional nasal speculum, the mucoperichondrial flap—the thin layer of tissue covering the septal cartilage and bone—is carefully elevated on one or both sides to expose the underlying deviated structures. The otolaryngologist then identifies bends, spurs, or excess cartilage and bone, and employs precise instruments—such as osteotomes, scissors, or microdebriders—to trim, reshape, or remove the obstructing segments while preserving a supportive L-shaped “strut” to maintain nasal framework integrity. If necessary, cartilage grafts may be harvested from septal remnants to reinforce weakened areas. Meticulous hemostasis is achieved with cautery or absorbable hemostatic agents before the mucosal flaps are repositioned and sutured together to cover the corrected septum. Soft silicone splints or absorbable packing may be placed to stabilize the septum and prevent adhesion formation. The entire operation typically lasts 30 to 90 minutes, after which patients awaken in a recovery area and are discharged home the same day with specific instructions for saline irrigations, activity restrictions, and follow-up visits to remove any non-absorbable materials and monitor healing.
What are the potential benefits and risks of septoplasty?
Septoplasty offers durable restoration of nasal airflow by straightening the deviated septum, leading to improved breathing, reduced congestion, fewer sinus infections, enhanced sleep quality, and greater tolerance of CPAP therapy in sleep apnea, as well as potentially improved smell and exercise capacity. It can also relieve headaches and facial pain caused by pressure imbalances, decrease snoring and mouth breathing, and improve overall quality of life. However, like any surgery, septoplasty carries inherent risks. Short-term complications include postoperative bleeding—usually controlled conservatively—pain or discomfort, swelling, bruising around the nose and eyes, and transient changes in smell or taste. More serious but rare risks involve septal hematoma, which can threaten cartilage viability if not promptly drained; septal perforation leading to persistent whistling, dryness, and crusting; formation of synechiae (adhesions) between nasal structures; infection; or anesthesia-related adverse events. Over-resection can compromise nasal support and lead to cosmetic deformities such as saddle nose. In some cases, residual deviation may warrant revision surgery. Careful patient selection, meticulous surgical technique, and diligent postoperative care—including saline irrigations, head elevation, and follow-up endoscopic evaluations—minimize these risks and optimize the likelihood of a successful outcome.
What are the alternatives to a septoplasty?
While septoplasty remains the definitive solution for mechanically correcting a deviated septum, many patients first explore medical therapies and minimally invasive procedures to manage nasal obstruction without realigning cartilage and bone. First-line management usually involves topical nasal corticosteroids, antihistamines, and decongestants to reduce mucosal swelling, often paired with regular saline irrigations to clear secretions and maintain mucosal health. For those whose symptoms stem from turbinate hypertrophy or nasal valve collapse, internal or external nasal dilators, radiofrequency ablation, laser turbinoplasty, or microdebrider-assisted reduction can target excess tissue and stabilize airflow with minimal downtime. Patients with allergic or inflammatory triggers may benefit from immunotherapy, biologic agents, and environmental controls to address underlying rhinitis. Balloon sinuplasty offers a non-resective option for concomitant sinus ostial stenosis by dilating drainage pathways without bone removal. Emerging techniques like absorbable nasal valve stents or thin implantable supports reinforce internal nasal valves without cartilage grafting. Lifestyle modifications—humidification, allergy avoidance, and breathing exercises—further support symptom relief.
Conclusion
In summary, septoplasty provides a durable, structural solution for correcting a deviated septum, restoring balanced airflow and reducing nasal resistance. By realigning or removing obstructive cartilage and bone while preserving the mucosal lining, this outpatient procedure alleviates chronic congestion, snoring, and sinus infections, and often improves sleep quality and exercise tolerance. Recovery is straightforward, with most patients returning to normal activities within a week and experiencing minimal discomfort when adhering to saline irrigations and activity guidelines. Although transient bleeding, swelling, or crusting can occur, serious complications are rare when the surgery is performed by an experienced ENT specialist.
