Most cases of pilonidal sinus can be treated by excision and primary closure of the wound in preference to excision and allowing the wound to granulate-a method still commonly taught and practised. With primary closure the recovery time is shortened, and the risk of recurrence is no greater than that following the other method. The experience of primary closure in 112 cases is recorded and a technique is described.
B. E. Juel‐Jensen (1959) studied this question.
