Background: Skull base chordomas are locally invasive tumors which able to extend in different directions with skull base invasion. Although they are histologically benign, they have invasive nature makes total resection virtually impossible to achieve in most cases and this lead to residual tumors after surgery. To decrease postoperative surgical resection morbidity of these tumors, gamma knife radiosurgery (GKRS) was performed as alternative management for these residual chordomas to evaluate its safety and efficacy. Materials and Methods: A retrospective study was made on eight residual skull base chordomas treated with GKRS between 2011 and 2015. The mean patient age was 49 years (range 30–73 years). Four patients harboring chordoma were male, and four patients were females with 1:1 ratio. All patients had undergone one prior surgery. Patients were treated with peripheral dose ranged between 12–15 gray (Gy) (mean 13.75 Gy) usually at 35% to 50% isodose curve (mean 38.8%). The maximum dose to the adjacent brain stem area ranged between 10 and 12 Gy. All patients were followed up from 8 to 39 months (mean 18 months). Results: The tumor control rate was 50% and 25% after 18 and 36 months, respectively, but we found that their wasdeclined in the tumor control rate with long follow-up time. Four tumors were stable in their size just for 18 months, and then there two of these tumors were progressed in their size, the other four patients showed progression in their tumors in their 1st year of treatment without sign of central tumor necrosis. Conclusion: Skull base chordoma patients complained from symptoms due to tumor mass effect which were not prospected to respond to GKRS alone as the aim of this type of treatment was the local tumor control, the tumor control rate declined with long follow-up time and this correlated with radioresistant nature of skull base chordoma. We advise a gross total resection to decrease the tumor volume, and this making gamma knife a reasonable treatment modality.

Abstract Idiopathic trigeminal neuralgia (ITN) is considered to be one of the most severe forms of pain in the human experience. The presence of neurovascular contact complex (NVC) with trigeminal nerve on pre-treatment MRI predicts an increased likelihood of adequate response to Gamma Knife Surgery (GKS). The aim of study is to evaluate Gamma Knife Surgery effectiveness and complications in treatment of refractory ITN when targeting the NVC complex. 58 patients with refractory ITN treated with GKS at our center were followed between 2005 and 2014. Mean maximum dose was 78 Gy, the NVC complex delineated by 3D-T2 MRI long relaxation sequence was the target of GKS. Clinical response was categorized on basis of pain outcome using BNI pain scale, into Group I in 60.3% of patients (significant response without medication), Group II in 22.4% (adequate response with medication) and Group III represented in 17.2% with failure of GKS to control pain. Mean duration of follow-up was 66 months. At final outcome patients who achieved significant and adequate pain control (Group I and Group II) were 82.8% at 2 years, 80% at 3 years, 77% at 5 years and 66% at 10 years. Favorable response rates were higher in patients who had no previous surgery 82.2% and those with duration of symptoms < 10 years in 77%. New or worsening facial numbness reported in 27.5%. GKS targeting detected NVC complex as the main associative pathology for treatment of ITN resulted in favorable outcomes compared with surgery in terms of pain relief and complication rates.

In order to evaluate the results of radiosurgery for vestibular schwannomas (VS) and to identify optimum treatment parameters, an analysis of tumor control, as well as incidences of hearing loss, facial and trigeminal neuropathies was undertaken. Between January 2013 and May 2014, 16 patients with VS received stereotactic gamma knife radiosurgery at International Medical Center. Median follow-up was 12 months. Regarding tumor volumes, 14 patients (87.5%) were less than 3 cm3 and 2 patients (12.5%) were between 3-4 cm3. From one to ten isocenters were utilized per tumor treated (median = 3). Minimum tumor doses varied from 12 to 20 Gy (median = 17 Gy). The 1-year actuarial tumor control rate was 90%. Hearing was preserved (stationary as pre radiosurgery) in 12 patients (75%) of cases and deteriorated in (4 patients) 25% of them. Facial affection improved in 2 cases (50%) and remained stationary in another 2 cases (50%). Trigeminal neuropathy and cerebellar ataxia were improved in all cases. Radiosurgery is a safe and effective treatment for vestibular schwannomas with acceptable morbidity that may be lowered by the use of multiple isocenter treatment techniques and by earlier treatment of small tumors.

We report three patients treated for cervical radiculopathy by anterior cervical discectomy and BOP grafting. Because of recurrent symptoms re-exploration was carried out 30 months later in the first case, 10 months in second and 8 months in the third case. At reoperation the grafts were disrupted into easily separable fibres. Histologically, there were no osteoblast or fibroblast cells or new bone formation. We suggest that contrary to the manufacturer's claims, the material acts only as a "spacer" and does not conduct bone formation. Bop Graft, Cervical Spine, Fusion, Graft. DOI:10.1080/02688699746717
