    Lumbar microdiscectomy with the simply modified taylor retractor
    (2021) Cetinkal, Ahmet
    Aim: To describe the modifications we made to the Taylor retractor (TR) used in routine spinal surgery and present the results of cases that underwent surgery with the modified TR. Materials and Methods: We made two basic modifications to the TR used in standard spinal surgery practice: reducing the size of the instrument and reshaping the blade part. The study included the cases in which we performed unilateral lumbar microdiscectomy (LM) at one level with standard and modified TR between January 2016 and August 2020. The preoperative and postoperative third-month low back pain and ODI scores were statistically analyzed. Results: The mean age of the 50 patients was 42 years, and the male/female ratio was 1.38. Except a skin infection in Group A, no other complication was seen. The mean follow-up period was 12 months. The length of incision was 28 mm in Group A and 17 mm in Group B. When the preoperative and postoperative third-month VAS and ODI scores were statistically analyzed in terms of low back pain, a significant difference was found (p<0.001). Conclusion: Microdiscectomy is a gold standard method in LDH surgery. TR is a practical and easily accessible surgical instrument in spinal surgery. Technological advances in optical systems have provided a significant reduction in normal tissue damage in LM. In addition, the modified TR we presented in this paper does not require a learning curve and can contribute to obtaining satisfactory results in terms of normal tissue damage and reducing postoperative low back pain complaints.

    Spinal Meningioma: Five-year experience of a single center
    (2021) Cetinkal, Ahmet
    Aim: To discuss the natural history of spinal meningiomas (SMs) in our series, surgical approach options, and pathology results in light of the literature. Material and Methods: Of the 151 meningioma cases operated on between June 2014 and August 2020 in our center, 11 with spinal localization were analyzed retrospectively. Results: Three (27%) of our cases were male, eight (73%) were female, and 7.2% of all meningioma cases were located in the spine. The patients mostly presented with paraparesis, and 73% of the tumors had a thoracic localization and 64% had a lateral spinal localization. We were able to reach a 90% Simpson grade I resection limit after the opening procedure performed with mostly hemilaminectomy or laminoplasty. The histopathologies of all our cases were reported as meningothelial and transitionally weighted WHO grade I, and their postoperative clinical states showed a favorable progression according to the Karnofsky and McCormick scales. Conclusion: WHO grade I histopathology and thoracic spinal location are predominant in SMs. With low recurrence and mortality rates, favorable outcomes can be obtained with gross total resection in most cases. Due to the slow course of SMs, care should be taken against the possibility of misdiagnosis.
