Microvascular decompression for a unique case of glossopharyngeal neuralgia with provokable symptomatic bradycardia: 2-Dimensional operative video.

ABSTRACT:

Background

Glossopharyngeal neuralgia is a rare neurovascular compression syndrome that can lead to paroxysmal craniofacial pain and sometimes cardiovascular symptoms.[1,2] The characteristic pathology involves a vessel (commonly a branch/loop of PICA) compressing the nerve at the root entry/exit zone at the brainstem.[1] Microvascular decompression is a commonly used treatment approach for patients that have failed conservative measures.[2].

Case description

A 72-year-old male presented to the ED following four episodes of syncope. The patient had a multi-year history of right-sided burning/stabbing pain involving the submandibular area and posterior throat. His syncope was related to symptomatic bradycardia that would occur during episodes of pain. His pain was exacerbated by speaking and swallowing and could be triggered by placing his finger in the right external auditory meatus. Interestingly, this maneuver would also trigger his bradycardia. The patient had failed previous pharmacotherapy, and a pacemaker had been placed to protect him from periods of hypotension. MRI/MRA of the brain and cervical spine were unremarkable. Due to his profoundly symptomatic status, the patient was offered a right retrosigmoid craniotomy for microvascular decompression of the right glossopharyngeal nerve. The patient had complete resolution of his pain and bradycardia immediately post-operatively. He was discharged on the second postoperative day and his pacemaker was ultimately removed. The patient continues to be pain free and off medication.

Conclusion

Here we present a video case report of microvascular decompression with favorable outcome for an interesting presentation of glossopharyngeal neuralgia. The patient gave informed consent for surgery and video recording.

Project description:ObjectiveCommon surgical treatments for trigeminal neuralgia (TN) include microvascular decompression (MVD) and percutaneous procedures (glycerol rhizolysis; thermocoagulation; and balloon compression). Although the efficacy of each procedure has been documented, direct comparisons of their relative efficacies for TN are lacking. We aimed to directly compare long-term outcomes after first-time MVD with percutaneous surgery in primary (idiopathic and classical) TN and identify predictors of outcome.MethodsWe conducted a retrospective analysis of prospectively collected data on 185 patients undergoing MVD and 129 undergoing percutaneous surgery. Procedures were performed by one of two neurosurgeons in a single centre; an independent observer collected long-term follow-up data by interviews, using the same outcome measures for all procedures.ResultsMVD patients were younger than those undergoing percutaneous surgery (P <.001). MVD provided superior initial pain relief (P <.001): 87.0% had Barrow Neurological Institute class I or II pain scores after MVD compared with 67.2% after percutaneous surgery. The complication rate for percutaneous procedures was 35.7% and for MVDs was 24.9% (P =.04), including minor and transient complications. Kaplan-Meier analysis demonstrated that MVD provided longer pain relief than percutaneous procedures (P <.001); 25% of patients had recurrence at 96 months following MVD compared with 12 months after percutaneous surgery. Subgroup analysis showed that balloon compression provided more durable relief amongst percutaneous procedures. Multivariate analysis revealed that post-operative numbness and age were prognostic factors for percutaneous procedures (P =.03 and .01, respectively).ConclusionsMVD provides better initial pain relief and longer durability of relief than percutaneous surgery, although carrying a small risk of major complications. Amongst percutaneous procedures, balloon compression gave the most durable relief from pain. Older age and post-operative numbness were predictors of good outcome from percutaneous surgery. These results can help clinicians to counsel patients with primary TN on neurosurgical treatment selection for pain relief.

Project description:BackgroundMicrovascular decompression (MVD) and partial sensory rhizotomy (PSR) provide longstanding pain relief in trigeminal neuralgia (TN). Given their invasiveness, complications can result from such posterior fossa procedures, but the impact of these procedures and their complications on patient-reported outcome measures (PROM), such as quality of life and distress, are not well established.MethodFive years after surgery, patients who underwent first MVD or PSR for TN at one institution, between 1982 and 2002, were sent a self-completion assessment set containing a range of PROMs: the Short Form-12 (SF-12) questionnaire to assess quality of life, the Hospital Anxiety and Depression Scale (HADS) to assess distress, and a questionnaire containing questions about postoperative complications, their severity and impact on quality of life. These findings and demographic data were compared between MVD and PSR.ResultsOne hundred and eighty-one of 245 (73.9%) patients after first MVD and 49 of 60 (81.7%) after PSR responded, and were included in analyses. The mean SF-12 scores of patients after MVD and PSR at five-year follow-up were significantly lower than English age-matched norms. Though there were no differences in SF-12 physical or mental component scores between the two procedures, patients after PSR were more likely to have case-level anxiety (RR = 3.3; 95% CI, 1.1-10.5; p = 0.03), had more postoperative complications, and of greater severity, including pain (RR = 2.52; 95% CI, 1.5-4.1; p < 0.001), numbness (RR = 5.9; 95% CI, 3.8-9.2; p < 0.001), burning sensations (RR = 3.0; 95% CI, 1.5-5.8; p = 0.001) and difficulty in eating (RR = 17.1; 95% CI, 5.6-53.1; p < 0.001), and these had a larger impact on quality of life for PSR compared to MVD.ConclusionsThe quality of life 5 years after MVD or PSR is poorer than in the general population and associated with postoperative complications such as pain, numbness, burning sensation and difficulty in eating. These complications are commoner after PSR than MVD, and this is associated with anxiety in PSR patients at five-year follow-up. However, these differences are not reflected by quality of life scores. Outcome measures need to incorporate patient experience after treatment for TN, and represent patient priorities for quality of life.
