Abstract
BACKGROUND There exists an increasing array of treatments proposed to prevent, alleviate, and abort symptoms of a migraine; however, for patients who undergo reconstructive microsurgery, caution must be taken to preserve vascular integrity. This study is the first-to-date scoping review of vascular and bleeding risk of current migraine therapies, with the purpose of identifying potential therapeutic agents for postoperative migraine management appropriate for microsurgical patients. METHODS Currently available migraine therapeutics were compiled from the UpToDate software system and the American Academy of Family Physicians. A PubMed literature review was performed for each therapeutic's effect on bleeding or vascular involvement. Data were compiled into tables of abortive, symptom-controlling and prophylactic, and nonpharmacologic treatments. Expert microsurgeons reviewed the data to provide recommendations for optimized patient care. RESULTS Triptans and other ergot derivatives demonstrated strong evidence of vasoconstriction and were greatly advised against for immediate postmicrosurgical use. Novel pharmaceutical therapies such as lasmiditan and calcitonin gene-related peptide antagonists have no literature indicating potential for vasoconstriction or hematoma and remain an investigational option for abortive medical treatment. For symptom control, acetaminophen appears the safest option, with clinical judgment and further research needed for use of nonsteroidal antiinflammatory drugs. Alternative treatment techniques may include migraine prophylaxis with botulinum toxin injection or nutraceutical treatment by means of magnesium supplementation or coenzyme Q10 administration, minimizing the need for additional medication in the postoperative setting. CONCLUSIONS Patients undergoing reconstructive microsurgery have a unique medical profile limiting the therapeutic options available to treat migraines. This review provides preliminary evidence to be considered as a guide for prescribing therapeutics for migraine in the postoperative setting.

Abstract
Background Modern surgical therapy of chronic headaches/migraines is essentially based on the release/neurolysis of extracranial nerves, which, when compressed or inflamed, act as trigger points and, as such, trigger headache attacks. The aim of this article was to describe a novel maneuver we use as an aid in the preoperative planning of occipital trigger sites. Methods In the period of January 2021-September 2023, we operated on 32 patients (11 men, 21 women, age range: 26-68 years), who underwent migraine surgery for occipital trigger point release. All patients were evaluated using the described preoperative maneuver. In a dedicated card, the levels of tenderness at each point were marked accordingly, differentiating them by intensity as nothing (-), mild (+), medium (++), or high (+++). Patients were then operated on at the points corresponding only to the ++ and +++ signs. Results At 6-month follow-up, we observed significant improvement (>50%) in 29 patients (91%), with complete recovery in 25 patients (78%). Conclusions In our experience, the maneuver described, in addition to being very simple, has been shown to have good sensitivity and reproducibility. We therefore recommend its use, especially for those surgeons beginning their practice in this particular area of plastic surgery.

Abstract
Background Trigger point deactivation surgery is a safe and effective treatment for properly selected patients experiencing migraine, with 68.3%-100% experiencing symptom improvement postoperatively. However, it is still unknown why certain patients do not respond. Obesity has been shown to be associated with worsened migraine symptoms and a decreased response to select pharmacotherapies. This study aimed to determine whether obesity may also be associated with an attenuated response to surgery. Methods A retrospective chart review was conducted to identify patients who had undergone trigger point deactivation surgery for migraine. Patients were split into obese and nonobese cohorts. Obesity was classified as a body mass index of 30 or higher per Centers for Disease Control and Prevention guidelines. Outcomes and follow-up periods were determined with respect to individual operations. Outcomes included migraine attack frequency, intensity, duration, and the migraine headache index. Differences in demographics, operative characteristics, and operative outcomes were compared. Results A total of 62 patients were included in the study. The obese cohort comprised 31 patients who underwent 45 total operations, and the nonobese cohort comprised 31 patients who underwent 34 operations. Results from multivariable analysis showed no impact of obesity on the odds of achieving a more than 90% reduction in any individual outcome. The overall rates of improvement (≥50% reduction in any outcome) and elimination (100% reduction in all symptoms) across both cohorts were 89.9% and 65.8%, respectively. Conclusion Obese patients have outcomes comparable to a nonobese cohort after trigger point deactivation surgery for migraine.

Abstract
Background Primary trigger point deactivation surgery has been successful in reducing or eliminating nerve compression headaches between 79% and 90% of the time. The aim of this review article was to discuss the factors that contribute to index trigger point deactivation surgery failure, the importance of reevaluating trigger points following failure, and the options for secondary surgery. Methods A literature search was performed using a combination of keywords involving "chronic headache" and "nerve deactivation surgery," in databases until February 2023. Results Data of 1071 patients were evaluated and included (11 articles). The failure rate after index trigger point deactivation surgery occurs is approximately 12%, primarily due to incomplete primary trigger point deactivation. Secondary trigger points may not appear until the primary trigger is eliminated, which occurs in 17.8% of patients. Reevaluation of previously diagnosed trigger points as well as uncovered trigger points and additional preoperative testing is indicated to help determine candidacy for further surgical deactivation. To address scarring that could contribute to failure, corticosteroid injection, acellular dermal matrix, adipofascial fat, or expanded polytetrafluoroethylene sleeves have been described with beneficial effects. For neuroma management, regenerative peripheral nerve interface, targeted muscle reinnervation, a combination of both, relocation nerve grafting, or nerve capping have also been described. Neurectomy can be performed when patients prefer anesthesia and/or paresthesia over current pain symptoms. Conclusion Secondary trigger point deactivation surgery is indicated when there is suspicion of incomplete deactivation, internal scarring, neuroma, or newly-diagnosed trigger points.

Abstract
Background Randomized controlled trials (RCTs) are integral to the progress of evidenced-based medicine and help guide changes in the standards of care. Although results are traditionally evaluated according to their corresponding P value, the universal utility of this statistical metric has been called into question. The fragility index (FI) has been developed as an adjunct method to provide additional statistical perspective. In this study, we aimed to determine the fragility of 25 highly cited RCTs in the plastic surgery literature. Methods A PubMed search was used to identify the 25 highest cited RCTs with statistically significant dichotomous outcomes across 24 plastic surgery journals. Article characteristics were extracted, and the FI of each article was calculated. Additionally, Altmetric scores were determined for each study to determine article attention across internet platforms. Results The median FI score across included studies was 4 (2-7.5, interquartile range). The two highest FI scores were 208 and 58, respectively. Four studies (16%) had scores of 0 or 1. Three studies (12%) had scores of 2. All other studies (72%) had FI scores of 3 or higher. The median Altmetric score was 0 (0-3). Conclusion The FI can provide additional perspective on the robustness of study results, but like the P value, it should be interpreted in the greater context of other study elements.

Abstract
BACKGROUND Refractory chronic migraine is a common and debilitating neurologic condition, affecting over 8 million people in the United States. It is associated with billions of dollars in lost productivity annually. Novel medical (anti-calcitonin gene-related peptide antibodies) and surgical treatment modalities have emerged for chronic migraine in recent years. The current study investigated the cost-utility of surgical versus medical management of refractory chronic migraine. METHODS A Markov cohort analysis using hybrid Monte Carlo patient simulation was performed to compare surgical decompression versus erenumab for the treatment of refractory chronic migraine in adults. Both societal and payer perspectives were considered. Primary model outcomes included incremental cost-effectiveness ratio, or cost per quality-adjusted life-year gained. RESULTS Over a 5-year period, migraine surgery was associated with an increase of 0.2 quality-adjusted life-year per patient when compared to erenumab. In terms of costs, the results demonstrated a $19,337 decrease in direct medical costs and a $491 decrease in indirect costs (productivity lost) for the surgery cohort compared to erenumab. Because surgery improved quality of life and decreased costs compared to erenumab, even when considering revision surgery needs, surgery was the overall dominant treatment in terms of cost-effectiveness. Sensitivity analyses demonstrated that surgery was cost-effective compared to erenumab when patients required therapy for at least 1 year. CONCLUSIONS Surgical deactivation of migraine trigger sites may pose a cost-effective approach to treating refractory chronic migraine in adults. This is especially the case when patients are anticipated to require therapy for more than 1 year.

Abstract
INTRODUCTION Little emphasis has been paid toward characterizing the socioeconomic burdens experienced by patients seeking treatment for chronic nerve injuries. The aim of this study was to characterize the direct and indirect costs faced by patients with chronic nerve injuries and their attendant health care utilization. MATERIALS AND METHODS A cross-sectional survey was distributed to all patients (N = 767) from a single nerve surgeon's practice treated for chronic nerve injuries in the ambulatory setting between 2014 and 2020. Data collected included demographics, etiology, comorbidities, duration and severity of symptoms, history of prior medical and interventional treatments, work or school time lost due to injury or treatment, money spent on treatment, and health care utilization. RESULTS Of the 767 patients, 209 (27.2%) completed the survey. Average age was 48.8 (SD = 19.1) years, 68.9% female and 31.1% male. Patients with chronic nerve injury reported significant direct costs, indirect costs, and health care utilization associated with their nerve injury symptoms. Direct costs consisted of out-of-pocket spending (68.4% had spent >$1000 per year), physician specialists visits (71.3% had seen at least 4 specialists), and prior interventional procedures intended to address symptoms. Indirect costs included lost time from work or school (24.6% had missed more than 12 months). Health care utilization, represented by annual emergency room visits and hospitalizations related to nerve symptoms, was increased relative to the general population. Detailed statistics are presented in the manuscript. CONCLUSIONS Chronic nerve injuries may be associated with a notable socioeconomic burden to the patient, including missed work or school, frequent physician visits and procedures, hospital visits, and out-of-pocket costs. Interdisciplinary algorithms recognizing a role for surgical evaluation in patients with chronic neuropathic pain due to underlying nerve injuries would facilitate future research into whether timely surgical intervention may reduce this economic burden.

Abstract
BACKGROUND Peripheral nerve decompression surgery can effectively address headache pain caused by compression of peripheral nerves of the head and neck. Despite decompression of known trigger sites, there are a subset of patients with trigger sites centered over the postauricular area coursing. The authors hypothesize that these patients experience primary or residual pain caused by compression of the great auricular nerve. METHODS Anatomical dissections were carried out on 16 formalin-fixed cadaveric heads. Possible points of compression along fascia, muscle, and parotid gland were identified. Ultrasound technology was used to confirm these anatomical findings in a living volunteer. RESULTS The authors' findings demonstrate that the possible points of compression for the great auricular nerve are at Erb's point (point 1), at the anterior border of the sternocleidomastoid muscle in the dense connective tissue before entry into the parotid gland (point 2), and within its intraparotid course (point 3). The mean topographic measurements were as follows: Erb's point to the mastoid process at 7.32 cm/7.35 (right/left), Erb's point to the angle of the mandible at 6.04 cm/5.89 cm (right/left), and the posterior aspect of the sternocleidomastoid muscle to the mastoid process at 3.88 cm/4.43 cm (right/left). All three possible points of compression could be identified using ultrasound. CONCLUSIONS This study identified three possible points of compression of the great auricular nerve that could be decompressed with peripheral nerve decompression surgery: Erb's point (point 1), at the anterior border of the sternocleidomastoid muscle (point 2), and within its intraparotid course (point 3).

Abstract
BACKGROUND With a 13 percent global prevalence, migraine headaches are the most commonly diagnosed neurologic disorder, and are a top five cause of visits to the emergency room. Surgical techniques, such as decompression and/or ablation of neurovasculature, have shown to provide relief. Popular diagnostic modalities to identify trigger loci include handheld Doppler examinations and botulinum toxin injection. This article aims to establish the positive predictive value of peripheral nerve blocks for identifying therapeutic surgical targets for migraine headache surgery. METHODS Electronic medical records of 36 patients were analyzed retrospectively. Patients underwent peripheral nerve blocks using 1% lidocaine with epinephrine and subsequent surgery on identified migraine headache trigger sites. Patients were grouped into successful and unsuccessful blocks and further categorized into successful and unsuccessful surgery subgroups. Group analysis was performed using paired t tests, and positive-predictive value calculations were performed on subgroups. RESULTS The preoperative Migraine Headache Index of patients with positive blocks was 152.71, versus 34.26 postoperatively (p < 0.001). Each index component also decreased significantly: frequency (22.11 versus 15.06 migraine headaches per month; p < 0.001), intensity (7.43 versus 4.12; p < 0.001), and duration (0.93 versus 0.55 days; p < 0.001). The positive-predictive value of diagnostic peripheral nerve blocks in identifying a migraine headache trigger site responsive to surgical intervention was calculated to be 0.89 (95 percent CI, 1 to 0.74). CONCLUSIONS To the authors' knowledge, this is the first study to investigate the positive-predictive value of peripheral nerve blocks as used in the diagnostic workup of patients with chronic migraine headaches. Peripheral nerve blocks serve as a reliable clinical tool in mapping migraine trigger sites for surgical intervention while offering more flexibility in their administration and recording as compared to established diagnostic methods. .

Abstract
Background: Chronic migraine headaches affect nearly 30 million Americans every year and are responsible for roughly 1.2 million emergency department visits annually. Many of the standard therapies commonly used to treat migraines are often unsuccessful and may furthermore introduce unwanted side effects. The purpose of this study was to identify independent predictors of clinical improvement in patients undergoing surgical nerve decompression for migraine. Methods: A retrospective chart review between 2010 and 2020 was conducted. The primary endpoint was clinical improvement at 1-year follow-up, defined as an independence from prescription medications. Patients were stratified into two groups: clinical improvement and treatment failure. Backward multivariable logistic regression was used to examine the associations between migraine improvement and different patient characteristics. Results: A total of 153 patients were included. In total, 129 (84.3%) patients improved and 24 (15.7%) did not. Significant associations with clinical improvement at multivariable logistic regression were found with acellular dermal matrix nerve wrap (OR = 10.80, 95%CI: 6.18–16.27), and operation of trigger sites four (OR = 37.96, 95%CI: 2.16–73.10) and five (OR = 159, 95%CI: 10–299). Conclusion: The use of acellular dermal matrix nerve wraps in surgery was significantly associated with clinical migraine improvement, as was operation at trigger sites four and five.

Data collected included demographics, specifics of the injury and symptoms, time to referral, and effects of the injury, surgery, and timing of surgery on QoL. RESULTS Of the 767 patients, 209 (27.2%) completed the survey. Average age was 48.8 years; 68.9% of patients were women and 31.1% men. At presentation, 68% had experienced symptoms for more than 1 year; 86.1% reported severity as being profound; 97.6% reported QoL was at least moderately negatively impacted by nerve injury; 70% felt they should have been referred earlier for surgical evaluation; 51.2% were not told that nerve surgery was an option for their problem; 83.1% felt that earlier referral would have improved their QoL. After surgery, symptoms were significantly mitigated in 55.5% of the patients, moderately mitigated in 21.5%. Patients reported QoL was significantly (59.8%) or at least moderately (76.6%) improved by nerve surgery. CONCLUSIONS The majority of patients reported that nerve injuries imparted a moderate to severe impact on QoL, and that surgical treatment improved QoL. Most patients felt that earlier referral for surgical intervention would have led to better outcome and positively impacted QoL. Interdisciplinary treatment algorithms, including a role for surgical intervention, may be helpful in facilitating timely diagnosis, referral, and thus improved outcomes.
