Pilonidal Info A-Z

Common Terminology Associated With Pilonidal Disease

Cleft-Lift

Cleft means valley, so this means to “lift” the natal cleft (valley) and flatten it. Simultaneously, scarred or pitted midline skin is shifted off the midline and to the side.

Drain

A clear tube buried under the skin during a pilonidal cleft lift operation to drain any accumulating fluid. This will help ensure the pilonidal wound heals well and more quickly.

Excision

Removal of diseased tissue.

Incision and Drainage

Cutting open a pilonidal abscess and draining pus after a pilonidal cyst becomes infected. It is done in the office most of the time under local anesthesia.

Midline Pore

Enlarged skin pores in the gluteal crease, also called pits. These are usually the beginnings of the progression of pilonidal disease.

Natal Crease (Cleft)

Middle fold between the buttocks. Often called gluteal cleft (crease).

Packing

Gauze that is used to help keep a wound draining after a pilonidal abscess is drained.

Pilonidal Abscess

A painful, red, swollen pilonidal cyst with or without draining pus or blood.

Pilonidal Cyst

Skin abnormality characterized by the presence of a pocket located under the skin, commonly found near the midline or the gluteal crease. This condition may cause discomfort or pain, may become infected, or may lead to the formation of tunnels into the surrounding tissue.

Pilonidal Disease

Open wounds, pits, cysts, and sinuses related to the gluteal cleft.

Pilonidal Sinus

When hair follicles shedding from the body become embedded in a midline pore, it can lead to a lump, known as a pilonidal cyst, or a tunnel, known as a pilonidal sinus. This may create a secondary opening elsewhere, leading to further complications.
