OBJECTIVES: For patients with medically unresponsive trigeminal neuralgia (TN), surgical options include micro vascular decompression (MVD), radiofrequency rhizotomy (RF), and stereotactic radio surgery (SRS). Multiple sclerosis (MS) is a demyelinating condition that can be associated with TN, but is not amenable to treatment with MVD. We sought to identify the outcome differences of patients with TN in MS undergoing SRS or RFR in an attempt to identify factors that may influence outcomes...

BACKGROUND: Severe spasticity adversely affects patient functional status and caregiving. No previous study has compared efficacy between dorsal root entry zone lesioning (DREZL) and selective dorsal rhizotomy (SDR) for reduction of spasticity. This study aimed to investigate the efficacy of DREZL and SDR for attenuating spasticity, and to compare efficacy between these two methods. METHODS: All patients who underwent DREZL, SDR, or both for treatment of intractable spasticity caused by cerebral pathology at Siriraj Hospital during 2009 to 2016 were recruited...

OBJECTIVE Selective dorsal rhizotomy (SDR) via limited laminectomy is an effective treatment of lower-extremity spasticity in the pediatric population. Children with spasticity are also at risk for neuromuscular scoliosis; however, specific risk factors for progressive spinal deformity requiring posterior spinal fusion (PSF) after SDR are unknown. The authors' goal was to identify potential risk factors. METHODS The authors performed a retrospective cohort study of patients who underwent SDR via limited laminectomy between 2003 and 2014 and who had at least 1 year of follow-up...

BACKGROUND: Spasticity is a motor disorder that interferes with mobility and affects the quality of life. Different approaches have been utilized to address patients with spastic diplegia, among which is selective dorsal rhizotomy (SDR). Although SDR has been shown to be efficacious in treating spastic patients, many neurologists and neurosurgeons are not well aware of the procedure, its indications, and expected outcomes due to the limited number of centers performing this procedure...

REVIEW
Michael George Zaki Ghali
The cervical spine is the most common site of traumatic vertebral column injuries. Respiratory insufficiency constitutes a significant proportion of the morbidity burden and is the most common cause of mortality in these patients. In seeking to enhance our capacity to treat specifically the respiratory dysfunction following spinal cord injury, investigators have studied the "crossed phrenic phenomenon", wherein contraction of a hemidiaphragm paralyzed by a complete hemisection of the ipsilateral cervical spinal cord above the phrenic nucleus can be induced by respiratory stressors and recovers spontaneously over time...

Javier Ros de San Pedro
Posterior communicating aneurysms are commonly associated with oculomotor nerve palsy. However, trigeminal nerve involvement among these aneurysms is a rare event with no previous analysis. In order to describe the main features of posterior communicating aneurysms causing trigeminal neuralgia (TGN-PComAAs) eight cases (six from the literature plus two more illustrative cases) were included in the present series. All cases were thoroughly studied in order to collect their epidemiological, radiological, clinical, therapeutic, pathogenic, and outcome data...

AIM: Selective dorsal rhizotomy (SDR) is a surgical treatment for spasticity in children with cerebral palsy (CP). Studies suggest long-lasting effects of SDR on spasticity; long-term effects on symptoms and function are not clear. This study tested whether adults with CP (average 22y after SDR) report less pain, fatigue, and functional decline than a retrospectively assessed non-surgical comparison group. METHOD: This was a case-control study. Eighty-eight adults with CP (mean age 27y; SDR=38 male/female/missing=20/16/2; non-surgical [comparison]=50, male/female=19/31) recruited from a tertiary care center and the community completed a battery of self-reported outcome measures...

REVIEW
Sarah K B Bick, Emad N Eskandar
Trigeminal neuralgia is characterized by severe, episodic pain in the trigeminal nerve distribution. Medical therapy is the first line treatment. For patients with refractory pain, a variety of procedures including microvascular decompression, percutaneous radiofrequency rhizotomy, percutaneous glycerol rhizotomy, percutaneous balloon compression, and stereotactic radiosurgery are available. We review the literature and suggest that microvascular decompression remains the gold standard operative therapy. For patients with recurrent pain or who are poor operative candidates, percutaneous radiofrequency rhizotomy offers the best pain response rates and has the advantage of being able to selectively target affected trigeminal divisions...

BACKGROUND: Percutaneous ganglyolysis treatment of trigeminal neuralgia is rarely associated with vascular complications, such as hematoma, subarachnoid hemorrhage, and stroke. Internal carotid artery injury may also occur after misguided needle placement, particularly far posteriorly or medially, resulting in carotid cavernous fistula. Anatomical variations of the foramen ovale can predispose those complications. CASE DESCRIPTION: A young woman diagnosed with trigeminal neuralgia during 11 years was submitted to a balloon rhizotomy by percutaneous approach to the trigeminal ganglion, with severe intraoperative bleeding...

BACKGROUND: Trigeminal neuralgia (TN) affects 7% of patients with multiple sclerosis (MS). In such patients, TN is difficult to manage either pharmacologically and surgically. Radiosurgical rhizotomy is an effective treatment option. The nonisocentric geometry of radiation beams of CyberKnife introduces new concepts in the treatment of TN. Its efficacy for MS-related TN has not yet been demonstrated. METHODS: Twenty-seven patients with refractory TN and MS were treated...
