Today, the most appropriate treatment for this condition has not been determined, and although cases of spontaneous absorption of the hematoma have been reported, the best treatment is surgery. There are different methods of surgery for this disease, each of which has its unique advantages and disadvantages. The present study was a comparison of open and endoscopic methods in terms of postoperative neurological symptoms, residual hematoma, recurrence, and operation time of the patients.</span></span></span></p> <h2><span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><span style="color:black">Material and Methods: </span></span></span></h2> <p style="text-align:justify"><span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><span style="color:black">In this clinical trial study, 32 patients were split into two groups using endoscopic and open techniques by simple random block method. The clinical examination of the patients and the CT Scan of the patients were reviewed and the necessary information was extracted from the patient&#39;s files. For follow-up, patients were followed up by phone after 6 months of discharge from the hospital.</span></span></span></p> <h2><span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><span style="color:black">Results: </span></span></span></h2> <p style="text-align:justify"><span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><span style="color:black">After spending a day in the intensive care unit, all patients had been transferred to the ward. The average duration of hospitalization and bleeding of patients</span> <span style="color:black">was significantly lower in the endoscopic group than in the non-endoscopic group(P<0.05). The duration of surgery did not differ significantly between the two groups. The frequency distribution of history of trauma, mortality, and neurological complications in the two groups of non-endoscopic and endoscopic patients was not significantly different from each other (P>0.05). The recurrence frequency distribution in the endoscopic group was significantly lower than in the non-endoscopic group (P=0.023).</span></span></span></p> <h2><span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><span style="color:black">Conclusion: </span></span></span></h2> <p><span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times=""><span style="color:black">Compared to the non-endoscopic procedure, the endoscopic method&#39;s recurrence rate was significantly lower</span></span></span></p> Chronic subdural hematoma, endoscopic surgery, open surgery 0 0 http://irjns.org/browse.php?a_code=A-10-690-2&slc_lang=en&sid=1 Hamidreza Doostabadi 100319475328460012698 0009-0009-6070-971X No Departments of Neurosurgery, School of Medicine, Hamadan University of Medical Sciences, Hamadan, Iran.
