Surgical treatment delay in patients with headache disorders and neuralgia correlates with poor postoperative outcome.

Overview

abstract

INTRODUCTION: Although nerve decompression surgery has proven to be effective in reducing symptoms in patients with head and neck neuralgia and headache disorders, it is currently not part of the treatment algorithms for headache disorders. Therefore, patients wait an average of 20 years from the onset of symptoms to surgery, resulting in high conservative treatment costs ($989,275.65 per patient) and patient morbidity. This study evaluated the clinical impact of treatment delays on surgical outcomes. METHODS: Overall, 282 patients who underwent nerve decompression surgery at Weill Cornell Medicine and Massachusetts General Hospital between September 2012 and January 2024 were enrolled. Information regarding demographics, onset of symptoms, and headache characteristics was collected using patient surveys. The treatment outcome was evaluated by the percentage of symptom reduction in terms of frequency, duration, and pain intensity. An area under the receiver operating characteristic analysis was performed to determine the optimal timepoint to undergo surgery. RESULTS: Postoperative symptom reduction and time between the onset of symptoms and surgery were negatively correlated (r = -0.22; p < 0.001). The most significant difference in outcome was found at 2.9 years from symptom onset; patients who underwent surgery before this timepoint reported an average improvement of 79 ± 23% versus 67 ± 35% in those who were treated after the timepoint (p = 0.021). CONCLUSION: Our results indicate that delays in undergoing nerve decompression surgery beyond 2.9 years from symptom onset leads to less favorable postoperative outcomes, underscoring the need for timely referral to peripheral nerve surgeons when conservative management fails. Nonetheless, even with delays in surgical intervention, patients continued to experience significant symptom reduction.
