    AIM: To evaluate the relationship between the surgical techniques, the waiting time for surgery, postoperative distance between the graft-bone margin and the percentage of bone resorption, we analyzed patients who underwent cranioplasty. Cranioplasty is a necessary surgery to preserve brain tissue and provide an appropriate microenvironment. MATERIAL and METHODS: In this study, patients who underwent autologous bone grafting after decompressive craniectomy by the Neurosurgery Clinic of University of Health Sciences Ankara Training and Research Hospital between 2018 and 2021 were examined. RESULTS: Thirty-nine patients who underwent autologous cranioplasty following decompressive craniectomy were included in the study. The average expected time for cranioplasty surgery following decompressive craniectomy was 16.97 +/- 13.478 weeks (min:2 max:62 weeks). The expected time between decompressive craniectomy and cranioplasty surgeries and resorption rates were compared. The resorption rate was above 30% in 7 of 10 patients with 24 weeks or more between craniectomy and cranioplasty, and less than 30% in 17 of 25 patients in surgeries less than 24 weeks (p=0.04). Following cranioplasty surgery, the distance between the graft-bone margin and the resorption rates were also compared. In this analysis, statistically significant differences were detected between the distance between the graft-bone border and the resorption rates. Resorption rates increased in 15 of 19 patients with a postcranioplasty distance of 1 mm or more (p<0.00001). CONCLUSION: Early cranioplasty surgery is important in order to reduce complications that may occur after craniectomy. In addition, it is important to keep the defect area small in size during craniectomy surgery and to keep the cutting edge thinner when the bone graft is taken, in order to reduce the development of bone graft resorption.

    Retrospective Examination of Patients with Spontaneous Cranial Intracerebral Hematoma
    (Turkish Neurosurgical Soc, 2024) Cengiz, Serdar; Erdem, Yavuz; Celik, Haydar; Tekiner, Ayhan; Kul, Halil; Kurtulus, Adem; Yildirim, Mehmet Emre
    AIM: To investigate the relationship among the modified Rankin scores of patients who had intracerebral hematomas at discharge, demographic characteristics of the patients, and the characteristics of the hematoma. MATERIAL and METHODS: In this study, patients diagnosed with intracerebral hematoma and treated at the Ministry of Health Ankara Training and Research Hospital Neurosurgery Clinic between January 2010 and December 2020 were examined retrospectively. The age, gender, comorbidity, anticoagulant-antiaggregant use, and Glasgow Coma Scale score of the patients were obtained from hospital records. The modified Rankin scale (mRS) was used to assess patients at discharge. RESULTS: Herein, a total of 114 patients with supratentorial intracerebral hematoma were evaluated. The modified Rankin score ranged from 0 to 6, with a mean score of 3.47 +/- 2.26. When the patients were evaluated based on their discharge status, the mortality rate was 33.3% (n=38). Fifty percent of the patients who used anticoagulant-antiaggregant died. High mRS scores were seen more frequently in advanced age. Among the other diseases of the patients, hypertension and the use of anticoagulant- antiaggregant were found to be statistically significant with high mRS scores (p<0.001). Patients with low Glasgow Coma Scale score at the time of admission had significantly higher mRS scores (p<0.001). CONCLUSION: Patients with advanced age, hypertension, and anticoagulant-antiaggregant use had a higher mRS score after hematoma formation. Preventable risk factors for spontaneous intraparenchymal hematomas are among the leading causes of disability, and early detection and treatment of underlying diseases are critical for hematoma prevention. Awareness about risk factors should be the priority to improve early diagnosis and reduce treatment disability rates.
