Fractures | Diseases of External Nose | Nose | Otorhinolaryngology (Ear Nose Throat / E.N.T) | 4th Year (Fourth Year) | MBBS | Detailed Free Notes
1. Definition
Fracture of the external nose refers to any break in the bony or cartilaginous framework of the nasal skeleton.
It is the most common facial fracture, accounting for over 50% of all facial trauma cases.
Because the nose is prominent, has minimal soft-tissue padding, and is structurally composed of delicate bones + flexible cartilage, even low-energy trauma can cause displacement.
2. Relevant Surgical Anatomy (Ultra-Expanded ENT Edition)
Understanding nasal skeletal anatomy is the foundation of fracture assessment and reduction.
2.1 Upper Third (Bony Pyramid)
-
Formed by paired nasal bones
-
Supported posteriorly by frontal process of maxilla
-
Joined superiorly to frontal bone (nasofrontal suture)
-
Thin → easily displaced
-
Fracture lines often extend into frontal process → causes deviation
Key Surgical Point:
A strong impact causes out-fracture laterally or in-fracture medially, creating internal valve narrowing.
2.2 Middle Third (Cartilaginous Vault)
Includes:
-
Upper lateral cartilages
-
Attached to septal cartilage (forming “keystone area”)
This region maintains airway patency; trauma here → internal valve collapse.
2.3 Lower Third (Tip Complex)
-
Lower lateral (alar) cartilages
-
Soft tissue + fibrofatty components
Tip injuries rarely cause true fractures but can cause distortion, asymmetry, and collapse when cartilage is torn or displaced.
2.4 Septum (Functional + Structural Pillar)
The septum is critical because:
-
It supports midline projection
-
It stabilizes both nasal bones
-
It defines symmetry
Septal fractures are often missed but more important than nasal bone fractures because they cause:
-
Persistent deviation
-
Chronic obstruction
-
External deformity
-
Saddle nose deformity (if septal cartilage necrosis occurs)
2.5 Nasal Mucosa and Soft Tissue
Highly vascular →
-
Swelling masks deformity
-
Infections spread quickly
-
Septal hematomas form easily
3. Mechanisms of Nasal Fracture (Deep ENT Breakdown)
3.1 Frontal Impact (Head-on Blow)
Examples:
-
Punch
-
Ball injury
-
Dashboard strike
Effects:
-
Bilateral displacement
-
Flattening of dorsum
-
Associated septal fracture
-
Internal valve collapse
3.2 Lateral Impact (Most Common)
Causes:
-
Hit from side
-
Elbow strike
-
Door impact
Effects:
-
One nasal bone depressed inward
-
Opposite bone displaced outward
-
Deviated septum
-
C-shaped external deformity
3.3 High-Energy Trauma
Examples:
-
Road traffic accidents
-
Falls from height
-
Assault with weapons
Effects:
-
Comminuted nasal bone fractures
-
Naso-orbital-ethmoid (NOE) fractures
-
Skull base involvement
-
CSF leak
3.4 Low-Energy Trauma
Examples:
-
Minor sports injuries
-
Children hitting furniture
Effects:
-
Green-stick fractures (common in children)
-
Minimal displacement
-
Swelling > deformity
4. Classification of Nasal Fractures (ENT Standard Systems)
4.1 Based on Displacement
A. Undisplaced fracture
-
Bone intact but cracked
-
No cosmetic deformity
-
No airway compromise
B. Displaced fracture
-
Shift in position of bony pyramid
-
Visible deviation
-
Requires reduction
4.2 Based on Laterality
-
Unilateral fracture
-
Bilateral fracture (more unstable)
4.3 Based on Complexity
Simple fracture
-
Single fracture line
-
No comminution
Comminuted fracture
-
Multiple bone fragments
-
Common in high-velocity injuries
4.4 Based on Associated Injuries
-
Nasal bone + septal fracture
-
Nasal bone + orbital rim fracture
-
NOE fracture
-
Skull base fracture
4.5 Pediatric Fractures (Special Category)
Children have:
-
Softer bones
-
Thicker periosteum
-
Higher elasticity
Thus:
-
Green-stick fractures common
-
Swelling disproportionate to injury
-
Septal injuries easily missed
-
Growth center can be damaged → long-term deformities
5. Clinical Features (Ultra-Expanded)
5.1 Symptoms
-
Nasal pain
-
Swelling
-
Epistaxis
-
Nasal obstruction
-
Difficulty breathing
-
Crunching sensation (crepitus)
-
Cosmetic deformity
5.2 Signs
External Signs:
-
Deviation of nasal dorsum
-
Widening or narrowing of nasal bridge
-
Flattening of nose
-
Bruising (periorbital ecchymosis)
-
Lacerations
Internal Signs:

CSF rhinorrhea (clear watery discharge)
-
Diplopia
-
Loss of smell
-
Malocclusion (suggests midface fracture)
-
Telecanthus (NOE fracture)
-
Nasal airway collapse on inspiration
Red flags require immediate intervention and imaging.
6. Special Emergency: SEPTAL HEMATOMA
This is the most dangerous nasal trauma complication.
Why?
Blood collects under mucoperichondrium →
-
Cuts cartilage blood supply
-
Leads to cartilage necrosis → saddle nose deformity
Features:
-
Bilateral, soft, boggy swelling
-
Severe obstruction
-
Pain
Management:
-
Immediate drainage
-
Antibiotics
-
Nasal packing
Delay = guaranteed deformity.

10. PRINCIPLES OF MANAGEMENT OF NASAL FRACTURES
Management aims to restore:
-
Function (airway patency)
-
Form (cosmetic symmetry)
-
Structural support (septal integrity)
Early swelling often hides the deformity, so timing matters.
10.1 Immediate Measures (Emergency Room Protocol)
A. Control Bleeding
-
Direct compression for 10–15 minutes
-
Ice packs to reduce swelling
-
Cautery only for clear bleeding sites
B. Assess Airway
-
Ensure unobstructed breathing
-
Look for severe septal deviation or hematoma
C. Rule Out SEPTAL HEMATOMA (Most Important Step)
A boggy, bilateral swelling must be drained at once.
D. Manage Soft Tissue Injuries
-
Clean lacerations
-
Close wounds in layers
-
Give antibiotics for exposed cartilage
E. Analgesics & Anti-inflammatory Agents
-
NSAIDs (unless bleeding risk)
-
Ice packs (20 min, 3–4 times/day)
F. Tetanus Prophylaxis
Always given in open injuries.
10.2 Definitive Treatment Overview
Two main approaches:
1. Closed Reduction
-
Most common
-
Performed when bones displaced
-
Best results within correct time window
2. Open Reduction
-
Complex fractures
-
Failed closed reduction
-
Severe comminution
-
Associated deformities
11. TIMING OF REDUCTION (CRITICAL ENT CONCEPT)
Adults:
-
Best time = 5–10 days after injury
-
Swelling subsides, bones still mobile
Children:
-
Best time = 3–5 days
-
Faster healing
-
Bones stabilize earlier
Waiting too long → callus formation → deformity becomes fixed.
12. CLOSED REDUCTION — STEP-BY-STEP ENT TECHNIQUE
Closed reduction is the gold standard for most nasal fractures.
12.1 Preparation
-
Local anesthesia with lidocaine + adrenaline
-
Topical vasoconstrictors
-
Mild sedation in anxious patients
-
Proper lighting and positioning
12.2 Instruments Needed
-
Asch forceps
-
Walsham forceps
-
Elevator (Freer)
-
Nasal speculum
-
Headlight
12.3 Manipulation Technique
A. Lateral Fracture (most common)
-
Insert Walsham forceps intranasally
-
Elevate depressed bone outward
-
Compress opposite side inward
-
Align dorsum symmetrically
B. Frontal Impact
-
Use upward pressure to restore nasal dorsum
-
Reposition both nasal bones together
-
Correct septal deviation if present
12.4 Internal Nasal Valve Assessment
After reduction, ensure airway patency.
If valve collapse present → consider spreader graft later.
12.5 Splinting
-
External nasal splint for 7–10 days
-
Internal packing if septal manipulation was done
13. OPEN REDUCTION — INDICATIONS & TECHNIQUE
Open reduction is required when:
-
Severely comminuted fractures
-
Old fractures (>14 days old)
-
Failed closed reduction
-
Open fractures with exposed bone
-
Fractures involving upper lateral cartilage & septum
-
Combined NOE fractures
13.1 Technique Overview
-
Incisions placed along natural creases
-
Elevate skin–soft tissue envelope
-
Restore bony pyramid using osteotomies
-
Reposition septal cartilage
-
Add structural grafts if needed
-
Close in layers
-
Apply splints
Open reduction = often combined with septorhinoplasty principles.
14. SPECIAL CATEGORY: SEPTAL FRACTURES (HIGH-YIELD)
Septal fractures are more important than nasal bone fractures.
Features:

-
Internal obstruction
-
Crepitus on palpation
-
Visible septal dislocation
Management:
1. Immediate care
-
Drain hematoma
-

2. Secondary correction
If persistent deviation remains → septoplasty after 3–6 months.
15. PEDIATRIC NASAL FRACTURES (ENT ULTRA-EXPANSION)
Children require special considerations:
15.1 Anatomical Differences
-
Bones → softer, pliable
-
Cartilage → proportionally larger
-
Perichondrium → thicker
-
Septum → critical growth center
15.2 Clinical Features
Swelling may appear dramatic; fractures subtle.
Signs:
-
Tenderness

D. Inverted V Deformity
Upper lateral cartilages displaced.
17.3 Septal Perforation
Causes:
-
Mucoperichondrial tears

23. TEXTUAL DIAGRAMS FOR SEO & EXAM MEMORY
Diagram 1 — Nasal Fracture Displacement (described)
Imagine the nasal bones as two slanted plates forming a pyramid.
-
A lateral blow depresses one plate and pushes the opposite outward.
-
A frontal blow flattens the apex of the pyramid.
Diagram 2 — Septal Hematoma (described)
Picture the septum as a flat wall sandwiched between two mucosal layers.
Hematoma → a soft balloon-like swelling on BOTH sides.
Diagram 3 — Algorithm for Reduction Timing
-
Days 0–3 → swelling
-
Days 3–5 → pediatric window
-
Days 5–10 → adult window
-
After day 14 → bones fixed
