Abstract

Abstract: BACKGROUND: Trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN) are hyperactive dysfunction syndromes (HDS) commonly caused by microvascular compression of their root entry zone. Cases of combined HDS involving 2 or more of these entities are extremely rare. Although microvascular decompression is the surgical treatment of choice, there are additional techniques that have been described as efficient methods to accomplish vessel transposition. OBJECTIVE: To our knowledge, we present the first reported case of triple simultaneous HDS successfully treated using the clip-sling technique to achieve microvascular decompression. We discuss several technical pearls and pitfalls relevant to the use of the sling suspension technique. METHODS: We report the rare case of a 66-yr-old male with combined simultaneous unilateral right-sided TN, HFS, and GPN because of a dolichoectatic vertebrobasilar system compressing the exit zones of the right trigeminal, facial, and glossopharyngeal nerves and present a literature review of combined HDS and their different surgical treatments. RESULTS: Symptomatic TN, HFS, and GPN have been reported 8 times in the literature with our case being the ninth. A retrosigmoid craniotomy was performed for microvascular decompression of the brainstem with a clip-sling suspension technique augmented with Teflon felt pledgets. The patient had immediate complete relief from TN, HFS, and GPN postoperatively. CONCLUSION: Microvascular decompression using the clip-sling technique via a retrosigmoid approach should be considered as a safe and effective option for transposition and suspension of the offending artery and decompression of the affected nerve roots in cases of combined HDS.
