Dorsal Hump : Causes & Correction Options

Every nose has a unique structure—some feature a straight, smooth dorsal line, while others develop a visible bump along the bridge, known as a dorsal hump. This protrusion (composed of bone, cartilage, or both) can create a harsh or severe facial appearance, motivating many to pursue dorsal hump reduction surgery (“hump filing”) for a softer, more refined contour.

What is a Nasal Hump?

A nasal hump (dorsal hump) refers to a convex protrusion along the nasal bridge, resulting from combined structural irregularities in both the bony and cartilaginous framework. This anatomical feature presents either as a pronounced camelback-like curvature or a subtle dorsal convexity, particularly visible in profile view. Nasal humps may develo

How Many Types of Nasal Hump Structures Exist?

Nasal humps can be classified into three primary anatomical types:

Bony Hump (Nasal Bone):

  • A dorsal protrusion composed exclusively of thickened nasal bone in the upper bridge
  • More prevalent in individuals of West Asian or European descent
  • Characterized by firm structural rigidity

Cartilaginous Hump (Upper Lateral Cartilage):

  • A mid-vault convexity arising from cartilage overgrowth
  • Commonly observed in East Asian patients with petite facial frameworks
  • Exhibits more flexibility than bony humps

Combined Osseocartilaginous Hump:

  • A complex deformity involving both nasal bones and cartilage
  • Requires dual-technique correction (osteotomy + cartilage refinement)
  • Most challenging to correct anatomically

Clinical Note:
Preoperative CT imaging is recommended to accurately assess hump composition, as hybrid structures demand customized surgical planning.

Why is Dorsal Hump Reduction Necessary?

Dorsal hump reduction (nasal hump filing) serves both functional and aesthetic purpose

  • Facial Harmony Enhancement
  • Nasal Profile Refinement
  • Augmentation Synergy
  • Psychological Benefit

A high nasal hump can affect facial appearance in the following ways:

An excessively high hump can make the nose appear rigid and harsh, resulting in a more aged look than one’s actual age. Particularly when viewed from the side, the nasal profile may appear uneven and irregular, affecting overall facial harmony. Additionally, it may interfere with silicone implant placement in cases of rhinoplasty, potentially causing the implant to lift or not adhere properly.

Benefits of Hump Reduction (Dorsal Hump Reshaping)

  • Creates a smoother, more refined nasal contour with improved dimension.
  • Enhances facial balance and harmony.
  • Softens facial features for a more delicate and feminine/masculine appearance.
  • Allows better silicone implant integration (in augmentation rhinoplasty), ensuring a more natural and secure fit.
  • Boosts confidence in side-profile photos, eliminating concerns over an uneven nasal bridge.

Disadvantages of Excessive Hump Reduction (Over-Resection of the Dorsal Hump)

  • Thinning of the nasal framework, which may lead to silicone implant visibility or displacement and increase the risk of future skin perforation.
  • Loss of natural nasal support, potentially resulting in an overly flattened or unnatural nasal profile.
  • Possible need for cartilage grafts (e.g., septal, ear, or rib cartilage) to reinforce the nasal structure if excessive weakening occurs.

Hump Correction Techniques at Doctor Tony Clinic

At Doctor Tony Clinic, our board-certified plastic surgeons perform comprehensive 3D nasal analysis to assess the nasal structure in detail before any procedure.

We employ specialized hump reduction techniques, including:

  • Precision Rasping: Ideal for minor humps, using meticulous sculpting for a smooth contour.
  • Osteotomy-Assisted Hump Reduction: Recommended for larger humps or deviated nasal frameworks, combining rasping with controlled bone repositioning for optimal symmetry.

Preoperative Preparation for Dorsal Hump Reduction Surgery

To ensure a safe and successful procedure, please adhere to the following guidelines:

  • Fasting: Refrain from food and water for 6-8 hours prior to surgery.
  • Medical History Disclosure: Inform your surgeon of any pre-existing conditions or medication allergies.
  • Blood-Thinning Medications: Discontinue aspirin, NSAIDs, or other anticoagulants as advised by your physician.
  • Lifestyle Restrictions: Avoid alcohol and smoking for at least 1 week before surgery to optimize healing.

Postoperative Care After Dorsal Hump Reduction Surgery

To ensure optimal healing and results, please follow these postoperative care instructions:

  • Cold Compress: Apply cold packs for 48 hours to minimize swelling.
  • Elevated Head Position: Sleep with your head elevated and avoid bending forward.
  • Avoid Direct Contact: Refrain from applying makeup or touching the nasal area.
  • Medication & Wound Care: Take prescribed medications and follow wound care protocols as directed by your surgeon.

Frequently Asked Questions About Dorsal Hump Reduction

Answer: Yes, this is commonly performed to achieve a more harmonious nasal contour. However, a thorough structural evaluation must be conducted first.

Answer: The procedure itself is painless under anesthesia. Postoperatively, mild discomfort or tightness may occur but is manageable.

Answer: Typically ranges from 35,000 to 80,000 THB, depending on complexity and surgical techniques required.

Answer: It may improve mild deviations. Significant deviations often require osteotomy (bone repositioning) for proper correction.

Answer: Revision surgery using auricular (ear) cartilage or costal (rib) cartilage grafts can reconstruct the nasal framework for proper implant support.

Conclusion

Dorsal hump reduction is a surgical procedure that can significantly enhance facial harmony by creating a softer, more balanced nasal profile while boosting confidence. However, it requires precise anatomical evaluation and expert surgical execution for optimal results.
