Nasal flap surgery is a reconstructive technique in which a surgeon moves a section of nearby tissue, still connected to its blood supply, to rebuild part of the nose that has been lost or damaged. The most common reason people need it is skin cancer removal, but traumatic injuries and congenital defects also lead to nasal reconstruction. Several distinct flap designs exist, each suited to different locations and sizes of defect on the nose, and surgeons choose among them based on where the missing tissue is, how deep the wound goes, and whether underlying cartilage or lining also needs replacement.
Why Flaps Instead of Something Simpler
The nose sits at the center of the face, so even small defects are hard to hide. It also has complex three-dimensional shape, with thin skin stretched over cartilage and bone, and every subunit (tip, ala, dorsum, sidewall) behaves a little differently. For very small wounds, a surgeon can sometimes close the edges directly or let the wound heal on its own. For larger or deeper defects, though, the options narrow to skin grafts or flaps.
Skin grafts involve taking a patch of skin from somewhere else and laying it over the wound. They heal, but they often end up with a slightly different color, texture, or contour compared to the surrounding nose. One study of post-Mohs reconstruction found that flap repairs had a significantly better cosmetic appearance score and that all flaps met acceptable cosmetic criteria, compared to only about three-quarters of skin grafts.1PubMed. Clinical outcome of cutaneous flaps versus full-thickness skin grafts after Mohs surgery on the nose A separate study in an Asian population found that local flaps generally outperformed grafts cosmetically, though the advantage was less clear in the nasal ala region, where only the bilobed flap consistently scored better than a graft.2PubMed.

Flaps bring their own blood supply, which makes them more reliable for healing and better at matching the surrounding tissue in thickness and color. The trade-off is that they require more surgery, more stages, and more follow-up. One retrospective comparison found that while flap patients and graft patients rated their final cosmetic results similarly on a satisfaction scale, the flap group needed far more touch-up procedures afterward, including steroid injections and dermabrasion sessions.3PubMed.

The Paramedian Forehead Flap
If there is a workhorse of nasal reconstruction, the paramedian forehead flap is it. The surgeon lifts a strip of forehead skin, keeping it attached at a narrow stalk (pedicle) near the inner eyebrow, and rotates it down to cover the nasal defect. This pedicle contains the supratrochlear artery, which provides a robust and consistent blood supply. The forehead skin is a close match to nasal skin in color and thickness, which is one reason surgeons have favored it for centuries.
The procedure is typically done in at least two stages. In the first, the flap is swung into place and sutured over the defect while the pedicle bridge remains intact, running from forehead to nose. The patient lives with this bridge for about three weeks, which allows the flap to develop a new blood supply from the recipient site. In the second stage, the pedicle is divided and the bridge removed. Some surgeons add a third intermediate stage to thin and shape the flap before final division, and comparative studies suggest this three-stage approach may offer advantages for large or complex defects and for patients whose blood supply is compromised.4PubMed Central. Two or Three? Approaches to Staging of the Paramedian Forehead Flap for Nasal Reconstruction
There is growing interest in shortening the timeline between stages. Research into early pedicle division has found that in selected patients, complete division can be performed after just one week if the flap paddle was thinned during the initial surgery. The reasoning is that a thinner flap has lower metabolic demand and can survive on its new blood supply sooner.5JAAD International. Complete division of the pedicle of the forehead flap is possible after 1 week of engraftment in selected patients This remains selective, though, and most surgeons still wait the traditional three weeks for safety.
The major downside is the forehead donor site. How the surgeon closes the gap left behind matters a lot for appearance. A recent study compared three closure methods and found that using a hemicoronal flap to close the donor wound produced the best cosmetic outcomes and the fewest complications, while skin grafting the forehead donor site produced the worst cosmesis even though it avoided wound-healing problems. Simple primary closure worked well for small defects under two centimeters but led to higher rates of wound separation and hair loss at the scar for medium-sized defects.6PubMed. Donor Site Closure in Paramedian Forehead Flap Reconstruction: Impact on Scar Quality and Patient Satisfaction Some surgeons have also experimented with injecting botulinum toxin around the donor site before surgery, which relaxes the forehead muscles and appears to improve scar quality.7Annals of Plastic Surgery. Donor Site Aesthetic Enhancement With Preoperative Botulinum Toxin in Forehead Flap Nasal Reconstruction
The Nasolabial Flap
The nasolabial flap borrows skin from the crease that runs from the side of the nose down to the corner of the mouth. Because the tissue there is naturally thick and slightly convex, it matches the curved surfaces of the nose well, particularly the nostril wing (ala). The scar at the donor site tends to hide neatly in the nasolabial fold, where a natural crease already exists. The blood supply is generous: the facial artery provides roughly three-quarters of the blood flow to this region, and the perforating vessels form a dense interconnected network in the tissue.8Chinese Journal of Plastic and Reconstructive Surgery. Nasolabial perforator flap for nasal defects
Though often thought of as a flap just for the nostril wing, the nasolabial flap can also be used for defects of the nasal tip, dorsum, and soft triangle.9PubMed Central. Expanded uses for the nasolabial flap A two-stage technique for alar reconstruction reported no major complications and no flap loss in a recent case series, with all patients rating their aesthetic outcomes as good and donor-site scars appearing inconspicuous.10PubMed Central. Nasal Ala Reconstruction Using a 2-stage Nasolabial Flap: Retrospective Analysis of a Refined Technique The nasolabial flap is smaller and less versatile than the forehead flap for truly large defects, but for medium-sized wounds on the lower third of the nose, it is a reliable option with a well-hidden donor scar.
Bilobed and Dorsal Nasal Flaps
Not every nasal defect needs tissue imported from the forehead or cheek. For smaller defects, local flaps that redistribute skin already on the nose itself can work well.
The bilobed flap is a clever two-lobed design. One lobe swings into the defect, and the second lobe covers the gap left by the first. The net effect is that skin is recruited from a zone with more laxity to fill a zone with less. It works best for defects roughly half a centimeter to a centimeter and a half in size on the lower third of the nose, where the skin is the tightest and hardest to move.11PubMed Central. Reconstruction of Nasal Skin Cancer Defects with Local Flaps Modifications to the design, like basing the flap medially and triangulating the primary defect at a specific angle, can help preserve the natural groove at the base of the nostril wing, which is an important aesthetic landmark.12Australasian Journal of Plastic Surgery. How I do a medially-based bilobed flap on the nasal ala
The dorsal nasal flap (sometimes called the Rieger flap) slides or rotates skin along the nasal dorsum. It was originally described for defects on the upper nose, but updated versions with longer flap designs can address defects further down toward the tip as well.13PubMed Central. Nasal Dorsum Rotation–Transposition Flap Associated with Guitar-String Sutures: One-Stage Reconstruction of Large Defects on the Nose Because it uses skin already on the nose, the color and texture match is essentially perfect. For certain lesions, it can even replace a staged forehead flap procedure with a single-stage operation.14PubMed. Beyond Rieger’s original indication; the dorsal nasal flap revisited
When the Problem Is Inside the Nose
Not all nasal flap surgery involves the outer surface. Holes in the nasal septum (septal perforations) cause crusting, whistling sounds, nosebleeds, and a persistent feeling of obstruction. Repairing them often requires flaps harvested from tissue inside the nose itself.
One approach uses tissue from the inferior turbinate, one of the ridges along the inside of the nasal cavity. In a small series, five patients had septal perforations closed with a turbinate flap combined with an acellular dermal matrix, and all perforations healed without recurrence over a follow-up period of up to 50 months. Every patient reported improvement in their preoperative symptoms, and no complications were seen at the donor site.15PubMed Central. Nasal Septal Perforation Repair with an Inferior Turbinate Flap and Acellular Dermal Matrix A larger study using a middle turbinate flap achieved complete perforation closure in 29 of 31 patients.16PubMed. Repair of nasal septal perforation using middle turbinate flap
Internal flaps also play a role in rhinoplasty. The spreader flap, for instance, is created by folding the upper lateral cartilage of the nose inward to widen the internal nasal valve, which is the narrowest point of the airway. A systematic review found that spreader flaps improved breathing function in twelve of thirteen studies analyzed.17Rhinology journal. Role of spreader flaps in primary rhinoplasty, functional and aesthetic outcomes: a systematic review A related technique, the cephalic lateral crural advancement flap, reshapes the lower cartilages of the nasal tip to improve both appearance and airflow. In a study of over 120 patients, roughly nine in ten reported improved nasal breathing, and no patient developed collapse of the internal valve after surgery.18PubMed. Assessment of Nasal Breathing Function and Tip Definition after the Implementation of the Cephalic Lateral Crural Advancement Flap Technique
Rebuilding All Three Layers
The nose has three structural layers: outer skin, a cartilage-and-bone framework in the middle, and a mucosal lining inside. Deep defects, like those left after aggressive cancer excision, can destroy all three. A skin flap alone cannot restore the shape or function of the nose; cartilage grafts are needed to provide contour and structural support, and a lining flap is needed to reconstruct the interior surface.19PubMed Central. Reconstruction of nasal defects: contemporary approaches
A common approach for these full-thickness defects is a three-layer reconstruction: a forehead flap for the outer skin, a reversed nasolabial flap for the inner mucosal lining, and an ear cartilage graft sandwiched between them for support. A series of 21 patients treated this way all healed successfully and were satisfied with both appearance and breathing.20PubMed. Three-layer reconstruction of lower third nasal defects using forehead flap, reversed nasolabial flap, and auricular cartilage The ear is a popular cartilage source because it can be harvested through a small incision behind the ear with minimal visible scarring. Rib cartilage is used for larger structural needs but involves a more significant donor-site recovery.
On the frontier of this area, researchers have begun engineering cartilage in the laboratory from a patient’s own cells. A first-in-human trial took cartilage cells from patients’ nasal septums, expanded them, and grew them on a scaffold to produce custom-shaped cartilage implants for alar reconstruction. After one year, all patients were satisfied with the aesthetic and functional results, and no adverse events were recorded.21The Lancet. Engineered autologous cartilage tissue for nasal alar lobule reconstruction: a first-in-human clinical trial This remains experimental, but it hints at a future where the need for ear or rib donor sites could diminish.
Complications and Who Faces Higher Risk
Flap surgery on the nose is generally reliable, but complications do occur. The most feared is flap necrosis, where part or all of the transplanted tissue dies due to inadequate blood supply. Smoking is a well-established risk factor: smokers have higher odds of developing flap necrosis after forehead flap reconstruction.22PubMed. Complications with forehead flaps in nasal reconstruction Nicotine constricts blood vessels, and the narrow pedicle of a forehead flap is already working at the limits of its vascular supply. Most surgeons strongly recommend that patients quit smoking well before scheduled nasal flap surgery.
Other possible complications include infection, wound separation, bleeding, and poor scarring. Partial flap loss, where just the edges fail, is more common than total loss and can usually be managed with local wound care or a minor revision. Nasal airway obstruction from flap bulk is another concern, particularly when tissue is rotated into the nostril area without adequate thinning. Newer intraoperative tools like indocyanine green fluorescence angiography allow surgeons to visualize blood flow through the flap in real time, which helps identify areas of poor perfusion before the surgery is finished.23PubMed Central. Evaluation of Intranasal Flap Perfusion by Intraoperative Indocyanine Green Fluorescence Angiography
What Sensation Feels Like Afterward
One aspect of nasal flap surgery that surprises many patients is the loss of sensation. The transplanted flap arrives with its blood supply but without its nerve connections, so the reconstructed area is initially numb. Sensation returns slowly, and the timeline varies widely from person to person.
A study that tested sensory recovery in facial flap patients found that within the first three months, only about one in ten could perceive light touch on the flap. By one to two years, roughly a quarter could feel light touch. After two years, three-quarters of patients had regained light-touch sensation. Temperature discrimination (telling warm from cold) recovered somewhat faster, with about six in ten patients able to do so within the first year, and over eight in ten managing it after two years.24JAMA Dermatology. Reinnervation of Flaps and Grafts of the Face The ability to distinguish sharp from dull followed a similar trajectory. The message for patients is that numbness is normal, recovery is gradual, and most people do regain meaningful sensation, but it takes years rather than months.
Quality of Life and Emotional Recovery
Living through nasal reconstruction involves real psychological strain. The period between flap placement and pedicle division, when patients walk around with a visible tissue bridge from their forehead to their nose, is often the hardest stretch emotionally. A multicenter prospective study measured quality of life at several time points and found that all three domains it tracked, including emotional well-being, satisfaction with appearance, and social functioning, improved significantly by about four months after the final stage of surgery compared to how patients felt before their cancer excision.25PubMed Central. Patient Quality of Life After Interpolated Flap Repair of Nasal Mohs Surgery Defects: A Multicenter Prospective Cohort Study
A study using the FACE-Q instrument to compare outcomes across different reconstruction techniques found that all methods, from simple skin grafts to complex multi-flap reconstructions, produced high patient satisfaction with scar appearance and facial appearance. One interesting finding was that patients who received skin grafts reported significantly more anxiety about cancer recurrence than those who had flap surgery.26European Journal of Plastic Surgery. Patient-reported outcomes after nasal reconstruction: FACE-Q assessment across techniques from skin grafts to complex reconstructions It is not entirely clear why; one possibility is that graft patients may feel their reconstruction was less thorough, or they may associate the visible textural differences with a reminder of their cancer.
Nasal Flaps in Children
Pediatric nasal reconstruction is uncommon but presents unique challenges. Children’s noses are still growing, so any flap placed during childhood will need to keep up with facial growth or risk distorting the nose over time. Beyond growth concerns, anatomical size matters for internal flaps. Research on the nasoseptal flap, commonly used to patch skull-base defects accessed through the nose, found that the septum in children under ten was often too small to provide a usable flap. In children over fourteen, the septum was comparable to adults and the flap worked reliably. The in-between group, ages ten to thirteen, needed individualized assessment based on their facial development and imaging.27PubMed.

Ancient Roots of a Modern Procedure
Nasal reconstruction is one of the oldest surgical procedures known. The practice traces back to at least 1500 BC in India, driven by the grim reality that nasal amputation was a common punishment in ancient societies. Around 600 BC, the surgeon Sushruta described using a leaf to template the wound and a cheek flap to supply tissue, a concept that would be instantly recognizable to a modern plastic surgeon. Italian surgeons in the 1400s and 1500s adapted the idea but used a pedicled arm flap, which required the patient to keep their arm attached to their face for weeks. The forehead flap, Sushruta’s original “Indian method,” eventually spread to Europe in the 1800s and has remained the cornerstone of nasal reconstruction ever since.28PubMed Central. The history of nasal reconstruction The tools have changed enormously, from bronze instruments to microsurgical precision, but the fundamental insight that nearby tissue with its own blood supply produces the best reconstruction has held up for over 2,500 years.
