Final answer:
An interrupted suture is typically the preferred choice for a small laceration on the cheek due to its ability to provide precise closure and minimize infection, which is important for cosmetic outcomes on the face.
Step-by-step explanation:
The type of suture used on a small laceration of the cheek would typically be an interrupted suture. This technique is preferred for facial lacerations because it allows precise skin edge approximation, minimizes the risk of infection, and can be adjusted to relieve tension on an individual suture if needed.
The continuous suture might be used in areas where rapid closure is needed and there is less concern about precise cosmetic results or if the laceration is long. Vertical mattress sutures and horizontal mattress sutures could be used in situations requiring additional wound eversion and tension relief but are less common for facial lacerations due to more prominent scarring. In facial lacerations, particularly on the cheek, cosmetic outcome is typically a high priority; hence, interrupted sutures are often chosen for the delicate skin and the need for aesthetic results.
