Anatomic location
Anatomic location
Location is an important consideration, particularly as cyst excision is often not truly medically required. Accordingly, the patient must be well informed and have reasonable expectations regarding the resulting scar. For example, if the patient has a cyst excised on the forehead or zygoma, they must understand that a scar will replace this cyst, and on these convex areas, a scar may be particularly evident. Cysts removed from thickerskinned areas (such as the back and flank), as well as the extremities, may require longer and larger excisions, as thinner-skinned areas are more flexible and malleable, allowing much of the cyst and contents to be squeezed out successfully from a smaller incision. Finally, cysts overlying anatomic danger zones should always be approached with caution, especially as they may extend deeper than anticipated; thus cysts on the preauricular area or over Erbโs point should be dissected carefully, and patients should be warned preoperatively regarding the risk of permanent nerve damage.
