Eyeball: enucleation - transpalpebral

pequis

Introduction

  • Removal of globe from Tenon's capsule plus a variable amount of extraocular muscles.
  • Two techniques:
    • Transconjunctival.
    • Transpalpebral.

Uses

Advantages

  • Simple technique for removal of painful eye in most cases, except where pyogenic infection or diffuse neoplasia are present.
  • Transpalpebral - preferable if any external eye infection or neoplasia is present.

Disadvantages

  • Cosmetically may be unsatisfactory but cosmesis is improved by placement of an intraorbital prosthesis.
  • Orbital infection may cause wound breakdown and rejection of prosthesis (if used).
  • Entire diseased tissue may not be resectable, ie orbital neoplasm.
  • Transpalpebral technique is slightly more difficult with slightly increased risk of hemorrhage from the skin.
