    Cervico-thoracic vertebra junction's cystic schwannoma: Case report
    (2014) Alkan, Bahadir; O?uzalp, Hüseyin; Koşar, Şule; Ömür, Dilek; Karata?, Ozan; Akman, Tarik Muhammed; Coşar, Murat
    Schwannomas which are one of the nerve sheath tumors located in the spinal column intradural-extramedullary. Schwannomas are generally seen in lumbar region and rarely located in cervical and cervico-thoracic junction. Schwannomas generally have solid characteristics however cystic companents rarely accompany to the solid tumor. So, cystic schwannomas are rarely seen in cervico-thoracic junction. In this report; we present a 59 year old female patient with C7-Th1 intradural extramedullar cystic schwannoma which complaints with pain and paresthesia at the left upper extremity. The lesion was extirpated with posterolateral approach. The histopathologic and immunohistochemical result of the patient was schwannoma. We also discussed radiological and pathological features and surgical approaches of the schwannomas.

    Comparison of Anterior Cervical Discectomy Fusion Techniques: Bladed and Non Bladed PEEK Cages
    (Turkish Neurosurgical Soc, 2016) Guven, Mustafa; Cosar, Murat; Alkan, Bahadir; Aras, Adem Bozkurt; Akman, Tarik; Safak, Ozbey; Karaarslan, Oznur
    AIM: The aim of this study is to compare the different types of fusion materials known as PEEK cages used during anterior cervical discectomy (ACD) surgery. MATERIAL and METHODS: A total of 67 patients were operated and evaluated retrospectively under two groups (group A: 35 PEEK cage patients, group B: 32 bladed PEEK cage patients) between 2009 and 2013. Preoperative and postoperative (postoperative first day, postoperative 1st, 3rd and 12-24th mo) images were obtained. The cervical disc heights, cervical and segmental lordotic angles of the operated levels were calculated. Pain assessment was performed and fusion rates were also compared. Mann-Whitney U test was applied to compare the outcomes. RESULTS: The pain scores (especially for arm pain) were decreased significantly in both groups after surgery regardless of the type of operation technique (P<0.05). There were no significant differences between both groups at the disc height measurements of operated levels in postoperative periods (P>0.05). In addition to these; there was no significant difference between both groups of segmental and cervical lordodic angles in postoperative periods (P>0.05). There was no statistically significant difference between the fusion rates and pain scores of both groups (P>0.05). CONCLUSION: The PEEK cage and bladed PEEK cages can be used safely to obtain fusion after ACD.

    Condensing osteitis of the clavicle in a man: Any relationship with tooth decay?
    (Pakistan Medical Assoc, 2014) Altiok, Inci Baltepe; Tokmak, Mehmet; Akman, Tarik; Alkan, Bahadir; Cosar, Murat
    Condensing osteitis of the clavicle is a rarely seen pathology since its first description in 1974. Although mechanical stress is claimed for aetiology, but remains a dilemma for physicians. The intermittent or steady pain is variable in intensity and generally localised at the medial end of the involved clavicle, supraclavicular fossa, ipsilateral anterior thorax and shoulder. In this report, we present a 28-year-old man with the regression of the condensing osteitis of the clavicle after the extraction of a decayed tooth.

    Effect of Using High-Speed Drill in Anterior Cervical Discectomy and Fusion
    (Turkish Neurosurgical Soc, 2016) Guven, Mustafa; Ceylan, Davut; Aras, Adem Bozkurt; Akbal, Ayla; Gokmen, Ferhat; Resorlu, Hatice; Alkan, Bahadir
    AIM: The objective of this study was to investigate the effect of using 2 different surgical techniques (curette or high-speed drill) in anterior cervical discectomy surgery on the healing of cases. MATERIAL and METHODS: Fifty-four operated cervical disc hernia cases were retrospectively examined in 2 groups. Discectomy and osteophytectomy were carried out in Group A by using a high-speed drill, while a curette was used for group B. Preoperative and postoperative computerized tomography and direct radiography were performed. Cervical disc height, cervical and segmental lordotic angles were calculated. The visual analogue scale and Odom's criteria were used in the assessment of pain and clinical healing. The fusion ratio of both groups was compared. The Mann-Whitney U test was used to compare data from the groups. RESULTS: Satisfactory results were obtained in the groups where high-speed drill and curette were used. Independently from the surgical technique, pain scores were significantly reduced in both groups after surgery. No radiologically significant differences were identified between the two groups within the postoperative period. CONCLUSION: Either high-speed drill or curette can be chosen for the osteophytectomy and discectomy stages of anterior cervical discectomy operations.

    Management of Type II Odontoid Fractures for Osteoporotic Bone Structure: Preliminary Report
    (Turkish Neurosurgical Soc, 2015) Cosar, Murat; Ozer, A. Fahir; Alkan, Bahadir; Guven, Mustafa; Akman, Tarik; Aras, Adem Bozkurt; Ceylan, Davut
    AIM: Anterior transodontoid screw fixation technique is generally chosen for the management of type II odontoid fractures. The nonunion of type II odontoid fractures is still a major problem especially in elderly and osteoporotic patients. Eleven osteoporotic type II odontoid fracured patients were presented in this article. MATERIAL and METHODS: We have divided 11 patients in two groups as classical and Ozer's technique.We have also compared (radiologically and clinically) the classical anterior transodontoid screw fixation (group II: 6 cases) and Ozer's transodontoid screw fixation technique (group I: 5 cases) retrospectively. RESULTS: There was no difference regaring the clinical features of the groups. However, the radiological results showed 100% fusion for Ozer's screw fixation technique and 83% fusion for the classical screw fixation technique. CONCLUSION; In conclusion, we suggest that Ozer's technique may help to increase the fusion capacity for osteoporotic type II odontoid fractures.
