The rhomboid flap for pilonidal disease.
BACKGROUND
There have been many surgical techniques described for the treatment of pilonidal sinuses. Recurrent disease causes significant morbidity particularly with time from work.


OBJECTIVE
To assess the rhomboid flap's role in promoting one-stage primary healing in pilonidal disease and to evaluate the morbidity and recurrence.


METHODS
Fifty-three patients were prospectively recruited of which 27 had previous multiple abscess formation requiring surgical drainage from their pilonidal disease, although none had acute disease at the time of surgery. By using the transposition flap, we were able to obliterate the natal cleft and therefore the rolling action of the buttocks between the cleft in these patients and thereby remove one of the factors involved in pilonidal disease. Hospital stay, healing time, wound infection, wound breakdown and recurrence were noted.


RESULTS
There were 47 males and 6 females with a median age of 28 years (range 16-64 years). Median follow-up was 24 months (range 3-36 months). Post-operative morbidity involved superficial wound infection in 7 (13%) which settled with out-patient dressings. There were four recurrences (7%), two occurred between the flap and the anal canal, and the other two in the flap margin needing intervention. All the patients healed their wounds and the median healing time was 14 days.


CONCLUSIONS
As this condition affects a predominantly young population causing significant time off from work, we feel that the Rhomboid Flap is useful for difficult cases in that it allows early return to full activity and does not necessitate prolonged postoperative care.
