Abstract
Objective
There are several surgical procedures tomanage chronic subdural hematoma (CSDH). At our institution, burr hole craniostomy combined with irrigation and drainage is used. We retrospectively compared the results of CSDH treatment obtained through either single burr hole or double burr hole craniostomy combined with irrigation and drainage and found that double burr hole procedures are as safe and effective as single burr hole procedures.
Methods
Fifty-seven patients with CSDH underwent surgery between January 2008 and December 2009. We compared the results of single burr hole craniostomy patients (Group I, n=32) with double burr hole craniostomy patients (Group II, n=25) with regards to operation time, duration of hospitalization, duration of drainage and rate of recurrence.
Results
The operation time was shorter in Group I (70.31 minutes) than Group II (82.01 minutes, p=0.026). There was no statistical difference between the two groups for postoperative hospitalization. The duration of drainage was shorter in Group II (3.37 days) than in Group I (4.16 days, p=0.046). The rate of recurrence was statistically lower in Group I (n=5, 15.6%) than in Group II.
Conclusion
Double burr hole craniostomy combined with irrigation and drainage can decrease the duration of drainage and rate of recurrence compared with single burr hole craniostomy. This might be related to a more flexible operation field to irrigate the remaining hematoma safely and effectively.
