Comparison of the Supine and Lateral Position in Microvascular Decompression of Trigeminal Neuralgia

Comparing the Supine and Lateral Position in Microvascular Decompression of Trigeminal Neuralgia

In this clinical trial, a total of 28 patients in two groups of 14-patient (supine position group and lateral position group) are evaluated in parallel without the control group, in a single blinded and randomized study. For randomization and selection of patients for the two groups, the letters S (for supine) and the letter L (for lateral) were placed in a bag. The neurosurgeon removes one of the papers before admitting the patient, thus selecting the surgical site and the patient group was done. Patients are unaware of the surgical location and the study is a single blinded study.

In this study, patients with typical trigeminal neuralgia in two groups (supine and lateral position) underwent Microvascular Decompression (MVD) in Sina Hospital of Tehran, Iran.

Inclusion criteria: definite diagnosis of typical trigeminal neuralgia who candidate of MVD and age more than 18 years old, . Exclusion criteria: pregnancy, multiple sclerosis, diabetic mellitus, extra-cranial masses that put pressure on the trigeminal nerve, intra-cerebral lesions in the thalamus or trigeminal brain stem pathway, history of posterior fossa surgery, history of psychiatric illnesses such as psychosis and cognitive disorders, Patients with contraindications to MRI, People unable to express their problems, such as people with verbal disorders, history of stroke or partial body and face paresis

Individuals are divided into two groups, one group undergoing surgery in the supine position and the other group in the lateral position.

Time of surgery, perioperative blood loss, Superior Petrosal Vein (SPV) ligation, application of brain retractor, complication, and cervical and facial pain

To select patients for the two groups, letters S (for Supine) and letters L (for Lateral) were placed in a bag. The neurosurgeon removes one of the papers before patient admission and thus the position of surgery was selected

Only Patients do not know the type of position during surgery. The neurosurgeon should be aware of the type of position before starting surgery and consider standard arrangements.

All information obtained from the patient as well as the patient's name will remain confidential. The research results will be published in general and in the form of information of the study group, and individual results will be provided, if necessary, without mentioning the name and personal details.
