IntroductionTrigeminal neuralgia is a highly invalidating pathology, whose natural course has been modified thanks to decompressive microvascular surgery. The intervention can be carried out either with a microscope or via an endoscopic technique. Our goal was to compare these two techniques for the treatment of this complex pathology.MethodsRetrospective, analytical study of a cohort of patients treated by a single surgeon at our institution, in the period between 2015 and 2021.ResultsWe identified 31 patients and divided them into two groups: 15 (49%) treated using the microscopic technique (group M), and 16 (51%) exclusively via an endoscopic one (group E). Differences were observed between the means of the size of the craniectomy in group M (3.7 cm) compared to group E (2.5 cm); The mean length of hospital stay for patients in group E was shorter (4.46 days compared to that of patients in group M, whose hospital stay averaged 2.43 days). There were no differences between the two groups regarding the length of the procedure. In both groups, the predominant compression was due to the superior cerebellar artery (SCA). Pain outcomes were equivalent, with every patient in both groups having an improved postoperative Barrow Neurological Institute Pain Intensity Score (BNI).DiscussionEndoscopic microvascular decompression is an attractive option for the resolution of neurovascular conflict as it provides functional results similar to the microscope technique, without requiring an extensive craniectomy and associated to shorter in-hospital stay, which is beneficial for both the patient and the institution.
