Which muscle is most commonly injured during inferior blepharoplasty?

• A. Inferior rectus
• B. Superior oblique
• C. Inferior oblique
• D. Medial rectus

Answer: (C)

The muscle that is most commonly injured during inferior blepharoplasty is the inferior oblique muscle. During this surgical procedure, the surgeon typically addresses the excess skin and fat around the lower eyelid to improve the aesthetic appearance. The inferior oblique muscle is located in close proximity to the lower eyelid and can be inadvertently affected when making incisions, especially if the surgeon is not careful in delineating the plane of dissection. Injury to the inferior oblique can lead to complications such as vertical diplopia due to the muscle's function in eye movement, particularly in the elevation of the eye when adducted. Surgeons need to have a thorough understanding of the anatomy in this region to minimize the risk of such complications. Other muscles such as the inferior rectus, superior oblique, and medial rectus have different anatomical locations or functions that make them less susceptible to injury during this particular procedure. While the inferior rectus is located below the eye, it is typically not as close to the surgical field as the inferior oblique. The superior oblique muscle is found more superiorly and medially, and the medial rectus is located on the medial side of the eye, making them less likely to be directly impacted during the typical incision
