    Chronic Subdural Hematoma Associated with Arachnoid Cyst of the Middle Fossa: Surgical Treatment and Mid-Term Results in Fifteen Patients
    (2018) Kircelli, Atilla; Musluman, Ahmet Murat; Ozsoner, Baris; Can, Songul Meltem; Yilmaz, Adem; Kaldirimoglu, Ayca; Sahin, Balkan; 0000-0003-2109-1274; 29131236
    AIM: To report neurological and radiological features, surgical management, and mid-term outcomes of patients with chronic subdural hematoma (CSDH) associated with ipsilateral arachnoid cyst (AC) of the middle fossa. MATERIAL and METHODS: A total of 453 patients with CSDH were treated at our clinic between August 2004 and August 2012. Of these patients, 15 had ipsilateral AC in the middle fossa. A single burr hole craniostomy was performed to drain the hematoma. The AC was left intact in 14 patients, and one patient had no surgical intervention. The follow-up period ranged from 13 to 88 months (mean 43.07 +/- 23.23 months). RESULTS: The patients with AC associated CSDH were found to be younger than the patients with CSDH alone, and the mean age of 58 patients was 13.15 +/- 13.17 years, while it was 11 +/- 14.22 years in the other patients. Eleven patients had experienced head trauma at 21-50 days before admission. Hematoma evacuation through a single burr hole with closed-system subdural drainage performed at 2-4 days after surgery improved the symptoms in all patients. Two patients developed subdural fluid collection, which was treated by subduroperitoneal shunt placement. CONCLUSION: Greater prevalence of ACs in patients with CSDHs has been reported in the literature. We recommend the drainage of the hematoma via a single craniostomy and to leave the AC intact as the first choice of treatment if the associated AC is a Galassi type I or II. Additional subduroperitoneal shunting may be performed in patients with Galassi type III cyst.

    Spinal Nerve Root Compositions of Musculocutaneous Nerve: An Anatomical Study
    (2014) Demircay, Emre; Musluman, Ahmet Murat; Cansever, Tufan; Yuce, Ismail; Civelek, Erdinc; Yilmaz, Adem; Kabatas, Serdar; Ozdes, Taskin; Sam, Bulent; 25448204
    AIM: This study was aimed to investigate the variations in the spinal nerve root compositions of musculocutaneous nerve and to confirm which spinal nerve root is the main ingredient in participating amount. MATERIAL and METHODS: A total of 20 fresh cadavers were dissected. Brachial plexus and its branches were extracted. Musculocutaneous nerve stump was traced back to the roots to identify its fascicular origin. The number of fascicles originating from a particular nerve root and their axial location with in the nerve were noted. RESULTS: The most frequent type of spinal nerve compositions of musculocutaneous nerve was C5, C6, and C7 with incidence of 60%. Musculocutaneous nerve had bundles from C5 root in all specimens, 90% of the specimens had contribution from C6 and only 70% of them had bundles from C7 root. There were a total of 46 (37.7%) bundles in C5 fascicles, 48 (39.3%) bundles in C6 fascicles, and 28 (22.9%) bundles in C7 fascicles. CONCLUSIONS: In electrophysiological studies it should be remembered that C7 or C6 lesions may not impair musculocutaneous nerve functions. The success of musculocutaneous nerve neurotization may be improved if care is taken to ensure whether or not C7 root is contributing to the musculocutaneous nerve.
