Which orbital procedure is specifically indicated to access the orbital contents for biopsy or removal of a foreign object?

• A. Orbitotomy
• B. Enucleation
• C. Evisceration
• D. Dacryocystorhinostomy

Answer: (A)

Accessing the orbital contents for biopsy or removal of a foreign object requires a surgical approach that opens the orbit while preserving the globe. This is orbitotomy, a procedure designed to provide direct access to the orbital cavity to reach tissues or locate and remove a foreign body without removing the eye. It allows targeted visualization and handling of the orbital contents. Enucleation and evisceration involve removal of the eye itself (enucleation removes the entire globe; evisceration removes intraocular contents but keeps the scleral shell), which is not about accessing the orbit for biopsy or foreign-body removal. Dacryocystorhinostomy is a tear drainage procedure that creates a path between the lacrimal sac and the nasal cavity and does not provide access to the orbital contents.
