Surgical management of the orbit in thyroid eye disease: lateral orbital decompression.

PURPOSE OF REVIEW

Lateral orbital wall decompression is one of many well established techniques available to surgeons in management of patients with clinically significant thyroid eye disease (TED). Several different surgical approaches have been described in the literature and are reviewed herein.

RECENT FINDINGS

Lateral orbital wall decompression remains a popular technique for surgical management of TED, with a recent American Society of Ophthalmic Plastic and Reconstructive Surgery survey showing that 22.6% of respondents preferred a single-wall procedure, with 36.8% of that subset preferring lateral wall decompression alone. Surgical techniques for lateral orbital wall decompression differ based on several steps, such as the incisional approach, whether to take an ab-interno versus ab-externo approach, and whether to remove orbital fat to achieve further decompression. In addition, technological advances have produced an array of tools available to the orbital surgeon to achieve efficient and accurate bone removal.

SUMMARY

Lateral orbital wall decompression for TED, despite being an older technique, remains a popular and well established procedure for orbital decompression. Though no randomized controlled clinical trial supports one decompression technique over another for TED, lateral orbital wall decompression offers many benefits such as its ease of access and visualization of the orbital space.
