Specialist treatment of pilonidal cysts, sinuses, and abscesses in Melbourne — from urgent drainage to minimally invasive pit picking and definitive surgery.
A pilonidal cyst forms in the natal cleft between the buttocks when hair and skin debris become trapped under the skin, causing inflammation, a painful lump, and often a discharging sinus tract. It most commonly affects young adults, particularly males, with risk factors including family history, obesity, hirsutism, and prolonged sitting. Dr Thomas Tiang authored the Colorectal Surgical Society of Australia and New Zealand (CSSANZ) Fellows' Weekend paper Management of Pilonidal Disease, and treats the full spectrum of the condition in Melbourne — urgent drainage of an infected pilonidal abscess, minimally invasive pit picking and the Gips procedure for limited disease, and excision with off-midline or flap closure for extensive disease. Treatment follows three principles: match the operation to the extent and acuity of the disease, keep incisions off the midline, and flatten the natal cleft so the wound heals in a dry, well-vascularised area. Consultations are in Essendon, with procedures performed at affiliated Melbourne hospitals.
Sub-topics
01
An infected pilonidal cyst can form a painful abscess requiring prompt incision and drainage, usually as a day procedure. The incision is placed off the midline wherever possible, which improves healing and preserves options for definitive surgery later.
02
Minimally invasive techniques for limited disease — one or two midline pits — where the pits are trephined, the underlying cavity curetted and irrigated, and healthy skin preserved. Published series report around 85 per cent long-term success, with markedly less pain and a return to normal activity within days.
03
For extensive or recurrent disease, excision with off-midline closure. A Cochrane review found off-midline closure has fewer wound breakdowns (3.9 vs 8.9 per cent), fewer infections, faster healing, and fewer recurrences (1.5 vs 6.8 per cent) than midline closure. The modified Karydakis flap and Bascom cleft lift both flatten the natal cleft to prevent the disease returning.
04
Management of disease that has failed previous surgery, including cleft lift techniques for chronic non-healing midline wounds — an approach originally described for patients with years of open wounds and high healing rates after a single, correctly planned procedure.
05
Midline pits without symptoms are best left alone — surgery for asymptomatic disease carries real morbidity and poor healing rates. For symptomatic patients, hair removal by shaving or laser depilation, hygiene, and structured wound care meaningfully reduce recurrence.
Published work
Dr Thomas Tiang wrote Management of Pilonidal Disease for the Colorectal Surgical Society of Australia and New Zealand (CSSANZ) Fellows' Weekend, 2024, as an ANZTBCRS Fellow at Austin Hospital, with co-author Mr Richard Brouwer. The paper reviews the evidence behind every technique offered here, and that same evidence guides how each patient is treated.
