AIM: The surgical results for @entity5663 ( @entity5663 ) with and without duraplasty in @entity1645 ( @entity1645 ) were compared retrospectively. MATERIAL AND METHODS: Thirty-nine cases of @entity1645 with and without @entity1644 ( @entity1644 ) were included. There were 18 @entity1 in the nonduraplasty and 21 in the duraplasty group. @entity1644 , @entity3976 ( @entity3976 ), preoperative symptom duration, and postoperative @entity1644 size were compared. RESULTS: No significant difference was found between improvement in the duraplasty group (81%) and the non-duraplasty group (61.1%). In cases whose symptom duration was 0-36 months, improvement in the duraplasty group (93%) was significantly better than in the nonduraplasty group (50%) (p < 0.01). The rate of syrinx regression was 92.3% in the duraplasty group and 12.5% in the non-duraplasty group (p < 0.05). In cases with @entity1644 , the improvement was 21.4% in the non-duraplasty group compared to 78.6% in the duraplasty group (p=0.056). In cases with @entity3976 greater than 10 mm, the improvement was 66.7% in the non-duraplasty group, whereas all six cases (100%) in the duraplasty group had improved. CONCLUSION: In @entity1644 associated cases, cases with @entity3976 greater than 10 mm, and whose symptom duration is less than 36 months, duraplasty is a more reliable choice despite a slightly higher rate of complications.
