Introduction

  • Surgical methods of treating an aural hematoma Ear: aural hematoma Ear: hematoma 01 :
    • Prolonged drainage using an indwelling drain and pressure bandaging.
    • Surgical incision and obliteration of the hematoma cavity.

Uses

Advantages

Indwelling drain

  • Improved success rate, compared to simple needle drainage.
  • Possible to perform in conscious dogs, under local anesthesia.
Surgical obliteration
  • Best success rate.
  • Surgical scarring means less risk of recurrence.

Disadvantages

Indwelling drain
  • Increased cost if sedation and repeat bandaging required.
  • Indwelling drain must remain in position for up to 3-4 weeks.
Surgical obliteration
  • General anesthesia required therefore increasing costs, and potential risk, to patient.
  • Cosmetic result may be poor owing to deformity from scar formation.
  • Head bandaging required for 5-10 days and an Elizabethan collar thereafter.
