Abstract
OBJECTIVE: To evaluate the clinical and functional results of a technical procedure used in the surgical treatment of congenital constriction ring (CCR) in children. MATERIALS AND METHODS: This was a retrospective study undertaken to evaluate the results of surgical techniques performed from January 1995 to December 2005 on 95 patients with 134 congenital constriction bands. Due to the drop-out of nine patients during follow-up, data on 86 patients (121 congenital constriction rings; average age at surgery 1 year 2 months) were analyzed. The extent of the constrictions was classified by according to the Patterson criteria. All patients were treated by two-stage sine plasty combined with removal of the fibrous groove and fasciotomy, with one-half of the ring removed during the first stage and the other half removed 1 week later during the second state. The surgical outcomes were assess according to the Moses criteria. RESULTS: Three types of CCR (Patterson criteria) were identified among the 86 patients (121 constriction rings): types I (5 patients, 4.1 %), II (107, 88.5 %), III (9, 7.4 %). Of the 121 constriction rings, good results were attained in 73.6 % and fair results in 26.4 %. Sensory deficits were seen in six patients immediately after the surgery but all six had improved to a normal condition at the final follow-up examination. There were no skin necrosis or wound healing problems. CONCLUSION: The combined sine plasty/removal of fibrous groove and fasciotomy method reported here is a simple and safe surgical technique for treating CCR in children.
