Nasal scar hyperplasia refers to the proliferation and contracture of scars on the skin of the nasal bridge or back due to burns or trauma, sometimes accompanied by deformities or displacement of the nasal tip, ala, and inner canthus. It alters the patient's appearance, causing significant psychological distress. Nasal scar hyperplasia has a relatively high incidence rate. It is generally estimated that the average annual incidence of burns is about 5–10% of the total population, with facial burns accounting for approximately 20%. Males are more commonly affected, with a male-to-female ratio of about 3:1. It is more prevalent among young adults and children, with about 80% of cases occurring before the age of 30. Treatment can involve scar excision with full-thickness skin grafting or partial or total nasal reconstruction using flaps or tubed pedicles, with favorable surgical outcomes.

bubble_chart Clinical Manifestations

1. There is scar hyperplasia and contracture on the skin of the nasal ala and nasal dorsum.
2. It may be accompanied by deformation and displacement of the nasal tip, nasal ala, and inner canthus.
3. It manifests as shortening of the nasal length.

bubble_chart Diagnosis

1. History of nasal trauma or burns;
2. Scar hyperplasia and contracture on the skin of the nasal bridge and dorsum;
3. May be accompanied by deformation and displacement of the nasal tip, ala, and inner canthus;
4. May present as a short nose.

bubble_chart Treatment Measures

1. Scar excision on the nasal bridge and dorsum, full-thickness skin grafting;
2. Release of scar contracture on the nasal bridge and dorsum, tissue repositioning, repaired with skin graft or flap.
3. Severe cases may require partial or total nasal reconstruction using flap or tube flap.

Expert Tip: Facial burns account for approximately 20% of burn cases. As a triangular pyramidal protrusion located at the center of the face, the nose is rarely spared in facial burns, often resulting in hypertrophic scars. Sufficient awareness of this is necessary. Preventing accidents and avoiding burns and trauma are crucial. In case of unfortunate incidents, prompt medical attention is essential. Doctors may determine whether to perform full-thickness skin grafting or partial/total nasal reconstruction using flap or tube flap based on specific circumstances.

bubble_chart Cure Criteria

1. Cure: The nasal tip, ala nasi, inner canthus, etc. are repositioned, and the dorsal nasal shape is close to normal.
2. Improvement: The nasal shape has improved, but the effect is still unsatisfactory.
3. No cure: The nasal shape shows no improvement.
