Physical Indications: The Dorsal Hump

A dorsal hump is one of the most common physical indications for rhinoplasty. It is a convexity along the bridge of the nose, composed of both bone (upper third) and cartilage (middle third). This feature often creates a perceived hook shape in profile and can make the nose appear larger than it is.

The hump disrupts the straight aesthetic line from the brow to the tip. Patients often feel their nose dominates their face, particularly in photos taken from the side. Reducing the hump requires precise removal of the excess bone and cartilage to create a straight or slightly concave profile.

  • visible convexity on the nasal bridge
  • osseocartilaginous composition (bone and cartilage)
  • disruption of the dorsal aesthetic line
  • dominance of the nose in profile view
  • desire for a straighter or softer profile

Physical Indications: The Bulbous Tip

PLASTIC SURGERY

A bulbous tip is characterized by a rounded, broad, or amorphous appearance at the end of the nose. This is often caused by hypertrophic (large) lower lateral cartilages that are convex, or by thick skin that masks the underlying definition.

Patients with a bulbous tip often feel their nose lacks refinement or looks “fleshy.” Correction involves trimming and reshaping the cartilages, frequently using sutures to bind them together and create a more triangular, defined point.

  • rounded or boxy nasal tip shape
  • hypertrophic lower lateral cartilages
  • lack of tip definition or refinement
  • thick skin masking cartilage structure
  • desire for a more defined, triangular tip

Physical Indications: The Drooping (Ptotic) Tip

A ptotic tip points downward, creating an acute angle between the nose and the lip. Long caudal septal cartilage, weak tip support mechanisms, or the effects of gravity and aging can cause this. It often becomes more pronounced when the patient smiles.

This indication can make the nose appear longer, and the face appear older. Surgical correction involves rotating the tip upward to open the nasolabial angle (typically 90-95 degrees for men, 95-105 degrees for women). Structural grafting is used to support this new rotation.

  • downward rotation of the nasal tip
  • acute nasolabial angle (<90 degrees)
  • plunging tip upon smiling
  • illusion of increased nasal length
  • Desire for upward rotation and lift

Physical Indications: Alar Flaring and Width

Alar flaring refers to nostrils that extend horizontally beyond the ideal vertical lines drawn down from the inner corners of the eyes. This can make the nose appear wide at the base, particularly during facial expression. Wide nostrils can also contribute to this appearance.

Alar base reduction (alarplasty) is the procedure used to correct this. It involves removing a wedge of tissue from the nostril base to narrow the width and reduce flare. This is common in ethnic rhinoplasty and provides a balanced triangular base view.

  • horizontal extension of the nostrils
  • wide nasal base width
  • flaring during smiling or expression
  • disproportionate nostril size
  • requirement for alar wedge excision

Physical Indications: The Crooked Nose

A crooked nose is a complex deformity where the nasal pyramid deviates from the central vertical axis of the face. This usually involves deviation of both the nasal bones and the septal cartilage. It creates marked asymmetry in the frontal view.

Correcting a crooked nose is one of the most challenging aspects of rhinoplasty. It requires osteotomies (controlled bone fractures) to reset the bones and aggressive septal reconstruction to straighten the central pillar. Spreader grafts are often used to splint the nose in the midline.

  • deviation from the central facial axis
  • asymmetry of the nasal sidewalls
  • C-shaped or S-shaped deformities
  • Complex involvement of the bone and septum
  • requirement for osteotomies and grafting

Biological Causes: Congenital Malformation

  • Many nasal characteristics are hereditary or congenital. The shape of the cartilage, the thickness of the skin, and the strength of the nasal bones are genetically determined. Congenital deformities can range from minor aesthetic variances to significant cleft lip and nasal deformities.

    Genetics dictates the starting point of the anatomy. For example, thick skin is a biological trait that limits the amount of definition that can be achieved. Understanding these biological constraints is crucial for surgical planning and managing expectations.

    • hereditary cartilage shape and strength
    • genetic determination of skin thickness
    • cleft lip and palate, nasal deformities
    • congenital absence of structural support
    • familial traits (e.g., dorsal hump size)

Biological Causes: Post-Traumatic Deformity

Trauma is a leading cause of acquired nasal deformity. Sports injuries, car accidents, or falls can fracture the nasal bones and dislocate the septum. If not treated immediately, the bones heal in a displaced position, leading to a permanent callus or deviation.

Post-traumatic noses often have significant scarring and fibrosis. The septum may be fractured in multiple places (crumpled). Surgery involves re-breaking the bones to reset them and reconstructing the septum to restore the airway.

  • nasal bone fractures and calluses
  • septal dislocation and deviation
  • post-traumatic fibrosis and scarring
  • saddle nose deformity from collapse
  • requirement for structural reconstruction

Biological Causes: Aging and Tip Descent

  • Aging affects the nose just as it does the rest of the face. The ligaments that hold the tip cartilages to the septum weaken over time. Simultaneously, the cartilage itself may weaken, and the skin loses elasticity.

    This biological process leads to drooping of the tip (ptosis) and a perceived lengthening of the nose. The skin may also thin, revealing previously hidden bony irregularities. Rhinoplasty for aging noses focuses on re-supporting the tip and restoring a youthful rotation.

    • Weakening of inter-domal ligaments
    • loss of tip support and projection
    • apparent lengthening of the nose
    • thinning of the dorsal skin envelope
    • gravitational descent of soft tissues

Functional Issues: Nasal Valve Collapse

  • The nasal valves are the narrowest parts of the airway. The internal valve is located in the middle third of the nose, and the external valve is at the nostril rim. Weak cartilage or a narrow angle can cause these valves to collapse inward during inhalation, blocking airflow.

    This functional issue causes significant breathing obstruction, especially during exercise or sleep. Spreader grafts are used to widen the internal valve, and alar batten grafts are used to strengthen the external valve to prevent collapse.

    • dynamic collapse during inhalation
    • obstruction of the internal nasal valve
    • weakness of the external valve (nostril rim)
    • Breathing difficulty during exertion
    • requirement for structural grafting support

Functional Issues: Septal Perforation

  • A septal perforation is a hole in the nasal septum. It can be caused by trauma, previous surgery, or chronic intranasal drug use. Small perforations may cause whistling; large ones can cause crusting, bleeding, and a feeling of obstruction due to turbulent airflow.

    Repairing a perforation is complex and often requires the use of tissue flaps from the nasal interior. While rhinoplasty usually focuses on the outside, restoring the integrity of the septum is vital for the health of the nasal lining and proper humidification of air.

    • hole in the cartilaginous or bony septum
    • Symptoms of whistling or crusting
    • turbulent airflow causing obstruction sensation
    • Risk of saddle nose collapse
    • requirement for intranasal flap closure

Functional Issues: Turbinate Hypertrophy

  • The turbinates are structures on the side walls of the nasal cavity that warm and humidify air. Chronic allergies or septal deviation can cause them to become permanently enlarged (hypertrophy), blocking the airway.

    Turbinate reduction is frequently performed alongside rhinoplasty. The surgeon shrinks the tissue or removes a small portion of the bone to open the breathing passages. This addresses the lateral component of airway obstruction, while the septoplasty addresses the central element.

    • chronic enlargement of the inferior turbinates
    • airway blockage refractory to medication
    • allergic or compensatory etiology
    • concurrent treatment with rhinoplasty
    • improvement of nasal airflow volume

The “Saddle Nose” Deformity

  • A saddle nose deformity is characterized by a collapse of the nasal bridge, creating a scooped-out appearance. This is caused by the loss of septal support, often due to trauma, autoimmune disease, or over-resection in a previous surgery.

    This is both an aesthetic and functional disaster. The collapse disrupts the airway’s structural integrity. Reconstruction requires major structural grafting, often using rib cartilage, to rebuild the dorsal height and support the tip.

    • collapse of the middle vascular vault
    • scooped-out dorsal profile
    • loss of septal structural support
    • significant aesthetic and functional impairment
    • requirement for rib cartilage reconstruction

FREQUENTLY ASKED QUESTIONS

What causes a bulbous tip?

The shape of the lower lateral cartilages often results in a bulbous tip. If these cartilages are wide, convex, or spaced far apart, they create a rounded appearance. Thick skin can also mask the definition of the underlying cartilage.

Yes, a broken nose can be fixed years after the injury. The bones will have healed in their crooked position, so the surgeon will need to perform osteotomies (controlled fractures) to straighten them and correct any internal breathing issues.

Turbinates are structures inside your nose that humidify air. If they become permanently swollen due to allergies or a deviated septum, they block breathing. Reducing their size opens up the airway without changing the external appearance of the nose.

This is caused by the depressor septi nasi muscle pulling the tip down, or by a lack of structural support in the tip itself. During rhinoplasty, the surgeon can release this muscle and strengthen the tip support to prevent it from plunging during animation.

It is permanent unless surgically corrected. The collapse of the nasal support structures causes it. To fix it, the surgeon must rebuild the bridge and tip using strong cartilage grafts, often taken from the rib or ear.
