Background:
The aim of this retrospective study was to describe a novel, simple surgical technique for the treatment of symptomatic Tarlov cysts.
Methods:
A total of 40 patients with symptomatic Tarlov cysts, admitted to our tertiary center between 1998 and 2019 constituted the study group. All patients underwent microsurgical puckering of the cyst, the technique we described to prevent a recurrence. Patients' symptoms, radiological findings, intraoperative findings, and clinical results were evaluated.
Results:
Of the 40 patients (5 males, 35 females) whose charts were reviewed, the mean age was 28.4 (range, 17-61) years. The mean follow-up was 8 (range, 3 months to 21 years) years. Preoperatively, the most common symptoms were leg pain and numbness of the lower extremity. Postoperatively, no major complications were observed. Clinical progression was halted in all patients; 33 (82%) patients recovered completely and seven (17%) patients reported partial recovery. Cystic cavity persisted radiologically in five (12%) patients, decreased in size in 30 (75%) patients, and regressed completely in the remaining five (12%) patients. None of the patients had permanent neurological deficits.
Conclusion:
Puckering of the cyst membrane is a safe and easy-to-perform surgical technique for symptomatic Tarlov cysts. This technique can be used almost in all cases instead of the commonly used microsurgical cyst excision or cyst fenestration.
