Inverted-V Deformity: Causes, Symptoms

Inverted-V deformity is a visible nasal contour problem that develops when the upper lateral cartilages lose their support after a dorsal hump reduction, causing the middle third of the nose to collapse inward. Seen from the front, the lower edges of the nasal bones become visible under the skin as two descending shadow lines that meet at the top of the bridge, forming the shape of an upside-down letter V. Beyond its cosmetic impact, inverted-V deformity is closely linked to internal nasal valve narrowing and can therefore cause breathing difficulty as well as an unnatural nasal appearance.

If you have noticed a groove, shadow, or pinched look on your nasal bridge after a previous rhinoplasty, this guide explains why inverted-V deformity happens, how it is diagnosed, and which surgical techniques are used to correct it.

What Is Inverted-V Deformity?

Inverted-V deformity is a structural complication of the middle nasal vault that occurs when the upper lateral cartilages separate from the nasal septum and the caudal edge of the nasal bones after dorsal hump removal. Without this connection, the cartilages drift inward and downward instead of forming a smooth, continuous bridge line. The caudal margins of the nasal bones then become outlined under the skin, creating a stepped contour that resembles an inverted V when the nose is viewed from the front.

The term was first described by plastic surgeon Jack Sheen in 1984, who identified it as one of the most common late complications following aggressive dorsal reduction without reconstruction of the nasal roof. It remains one of the most frequently seen reasons patients seek revision rhinoplasty today, particularly in noses with thin skin, short nasal bones, or long upper lateral cartilages.

What Causes Inverted-V Deformity After Rhinoplasty?

Inverted-V deformity almost always develops as a consequence of how the dorsal hump was managed during a previous nose surgery. The main contributing factors include:

Excessive Dorsal Hump Resection

When too much bone and cartilage is removed from the nasal bridge, the natural roof connecting the nasal bones to the upper lateral cartilages is opened. If this “open roof” is not rebuilt, there is nothing left to hold the cartilages in their original outward position.

Lack of Middle Vault Reconstruction

The middle vault — the segment where the nasal bones meet the upper lateral cartilages — depends on structural support to stay open. When spreader grafts or spreader flaps are not placed after hump reduction, the cartilages lose their lateral support and collapse toward the septum, narrowing the bridge and producing the visible step-off.

Thin Nasal Skin

Patients with thin, low-sebaceous skin have little soft tissue to camouflage irregularities underneath. In these patients, even a mild degree of middle vault narrowing can appear as a sharply visible inverted-V shadow, whereas the same anatomical change might be far less noticeable in thicker skin.

Closed Rhinoplasty Technique Limitations

Inverted-V deformity is reported more frequently after closed rhinoplasty, where limited visibility can make it harder for the surgeon to precisely reconstruct the middle vault compared with an open approach.

Scar Tissue From Previous Surgery

In patients who have already undergone one or more nasal surgeries, scar tissue can prevent the upper lateral cartilages from being repositioned using tension-based techniques alone, making structural grafting the only reliable long-term solution.

Signs and Symptoms of Inverted-V Deformity

Inverted-V deformity is usually easy to recognize once you know what to look for. Common signs include:

• A visible groove or shadow running down each side of the nasal bridge, meeting at the top like an inverted letter V
• A pinched, narrow appearance in the middle third of the nose, especially noticeable in photographs taken under direct light
• Palpable, sharp bony edges felt when running a finger along the bridge
• A sudden change in the width of the nose between the upper (bony) and middle (cartilaginous) segments
• Nasal obstruction or difficulty breathing through the nose, particularly during exercise or at night
• A sensation that one or both nostrils collapse inward when inhaling deeply

If several of these signs are present after a previous rhinoplasty, it is worth having the nose assessed by a surgeon experienced in revision cases.

Inverted-V Deformity and Nasal Valve Function

Inverted-V deformity is not only a cosmetic concern. As the upper lateral cartilages collapse inward, they narrow the internal nasal valve, the angle between the septum and the upper lateral cartilage that represents the narrowest — and most airflow-sensitive — segment of the entire nasal airway. Because of this direct anatomical relationship, most patients with a visible inverted-V deformity also experience some degree of nasal obstruction, even if they never had breathing problems before their first surgery.

This overlap is why inverted-V deformity is frequently discussed alongside nasal valve collapse: correcting the visible shadow on the bridge and restoring airflow through the internal nasal valve are, in most cases, addressed with the very same surgical maneuver.

How Is Inverted-V Deformity Diagnosed?

Diagnosis begins with a detailed physical examination. The surgeon visually inspects the nose from the frontal and oblique views to assess the depth and symmetry of the shadowing, then palpates the bridge to feel for sharp bony margins and determine skin thickness. A modified Cottle maneuver or a similar valve-function test is typically used to check whether gently supporting the sidewall improves airflow, which helps confirm internal nasal valve involvement. Nasal endoscopy may also be used to examine the internal airway, and in more complex or multiply revised cases, imaging can help evaluate the alignment of the nasal bones and remaining cartilage framework before planning surgery.

How to Prevent Inverted-V Deformity During Rhinoplasty

Because inverted-V deformity is largely a preventable complication, the most effective strategy is choosing a surgical technique that reconstructs the middle vault at the same time the dorsal hump is reduced. Modern preventive approaches include:

• Routine spreader grafts or spreader flaps placed immediately after hump reduction to rebuild the roof and keep the upper lateral cartilages in their natural outward position
• Dorsal preservation techniques, which reshape rather than resect the bony-cartilaginous hump, avoiding the “open roof” problem altogether in suitable candidates
• Careful patient-specific planning for high-risk anatomy, such as short nasal bones, long upper lateral cartilages, or thin skin, where extra structural support is planned proactively
• Caudal traction and T-frame reconstruction, techniques used during primary surgery to reposition the upper lateral cartilages before scar tissue can form in the wrong configuration

Patients planning a first-time rhinoplasty that involves dorsal reduction should specifically ask their surgeon whether middle vault reconstruction with spreader grafts or an equivalent technique is part of the surgical plan.

Treatment Options for Inverted-V Deformity

Non-Surgical Camouflage With Filler

In mild cases where the patient does not want surgery, injectable filler can be placed along the concave shadows beside the visible bony edges to visually smooth the bridge line. This approach is temporary, does not correct the underlying structural collapse, and does not improve any associated breathing problems, so it is generally reserved for patients who are not seeking a permanent or functional solution.

Surgical Correction With Revision Rhinoplasty

The definitive treatment for an established inverted-V deformity is structural correction through revision rhinoplasty. Because the deformity is caused by a loss of structural support, filling in the depression from the outside cannot fix the problem long-term — the middle vault has to be physically reopened and rebuilt from within. During this procedure, the surgeon typically works through an open approach for maximum visibility and precision, then:

• Elevates the skin to expose the collapsed upper lateral cartilages and nasal bone edges
• Harvests cartilage from the septum, and from the ear or rib if septal cartilage is insufficient due to a prior surgery
• Places bilateral spreader grafts (or spreader flaps) between the upper lateral cartilages and the septum to widen the middle vault back to its natural anatomical width
• Restores a smooth, continuous transition from the bony dorsum to the cartilaginous middle third, eliminating the visible step-off
• Reopens and stabilizes the internal nasal valve, which frequently improves nasal airflow at the same time the aesthetic deformity is corrected

In cases where the nasal tip has also lost projection or rotated upward as a secondary effect of the collapse, extended spreader grafts anchored to a columellar strut may be used to correct tip position in the same operation.

What to Expect From Revision Rhinoplasty

Correcting inverted-V deformity is a structural procedure, and results depend heavily on precise surgical planning. Here is what the process generally involves:

• Consultation and assessment: the surgeon examines skin thickness, cartilage integrity, and internal valve function, and may use photographs or imaging to plan the exact grafts required.
• Surgical technique: the open approach is preferred in almost all revision cases because it allows direct visualization of the collapsed cartilages and precise graft placement.
• Cartilage source: the septum is used first when enough cartilage remains; ear or rib cartilage is used when septal cartilage has already been depleted by a previous operation.
• Surgery duration: revision procedures to correct middle vault collapse typically take between 3 and 4 hours, depending on complexity.
• Early recovery: protective splints are worn for around 1–2 weeks, with visible swelling and bruising gradually settling over the following 2–3 weeks.
• Final results: because cartilage grafts need time to integrate and residual swelling takes time to resolve, the final shape and breathing improvement are best assessed after approximately 12 months.

If you have a visible shadow, groove, or breathing difficulty following a previous nose surgery, an experienced surgical team can determine whether inverted-V deformity is the underlying cause and plan the correct structural correction.
