Final answer:
The statement that does not refer to pilonidal cyst surgery is the formation of a Z-plasty, which is a technique usually used in plastic surgery to reorient the tension on scars, not typically associated with pilonidal cyst treatment.
Step-by-step explanation:
The question pertains to a surgical procedure known as pilonidal cyst surgery. When considering the options provided, all relate to typical steps or aspects of the procedure except the formation of a Z-plasty. A Z-plasty is typically associated with plastic surgery procedures and is used to improve the functional and cosmetic appearance of scars. It involves creating a Z-shaped incision to reorient the tension on a scar. In the context of pilonidal cyst surgery:
- Excision of the cyst is the removal of the cyst itself.
- Primary closure of the defect refers to closing the surgical wound primarily, which is one of the options for wound closure after the cyst has been removed.
- Using a drain postoperatively can be part of the management to prevent fluid accumulation in the area where the cyst was removed.
Therefore, the statement referring to the formation of a Z-plasty does not typically apply to pilonidal cyst surgery and is the correct answer.
