Overview
Contusion of the infraorbital nerve can occur as an adverse event following aesthetic procedures in the infraorbital region. Hyaluronic acid injections are a common noninvasive treatment for hollowing in this area 1.Diagnosis
Adverse events following infraorbital hyaluronic acid injections may include ecchymosis and edema 1.Management
The choice of injection tool (needle versus cannula) influences the incidence of adverse events 1.
Needles are associated with a greater risk of ecchymosis 1.
Cannulas are associated with a greater risk of edema 1.Key Recommendations
Discuss the potential adverse events of ecchymosis and edema with patients prior to infraorbital hyaluronic acid injections 1.
Be aware that needles are associated with a higher incidence of ecchymosis compared to cannulas during infraorbital hyaluronic acid injections 1.
Be aware that cannulas are associated with a higher incidence of edema compared to needles during infraorbital hyaluronic acid injections 1.References
