Transconjunctival approach revisited and anatomical considerations

Area of Science:

• Ophthalmology
• Plastic Surgery
• Anatomy

Background:

• The transconjunctival approach, established in 1923, is widely used for orbital floor, medial/lateral wall, and infraorbital rim fractures.
• It is also employed in aesthetic and access surgeries.
• Complex lower eyelid anatomy can complicate transconjunctival surgical approaches.

Purpose of the Study:

• To revisit the detailed anatomy relevant to the transconjunctival approach.
• To discuss surgical steps for preseptal and postseptal dissection.
• To introduce and describe the anatomy of the interseptal space.

Main Methods:

• Anatomical review of the lower eyelid and orbit.
• Description of surgical techniques for transconjunctival dissection.
• Discussion of the interseptal space anatomy.

Main Results:

• Detailed anatomical considerations for the transconjunctival approach are presented.
• Surgical steps for preseptal and postseptal dissection are outlined.
• The anatomy of the interseptal space, a potential space, is described.

Conclusions:

• Understanding the intricate anatomy is crucial for successful transconjunctival surgery.
• The interseptal space offers a novel perspective for surgical dissection.
• This work aims to enhance the safety and efficacy of transconjunctival procedures.
