RESUMO
Balance in Alzheimer disease (AD) patients is not rigorously understood. In this study, we characterize balance using qualitative [Berg Balance Scale (BBS)] and quantitative measures (posturography) and assess relationships between qualitative and quantitative balance measures in AD. Patients with mild-moderate AD (n=48) were recruited. BBS scores and posturography metrics, including medial-lateral sway range, anterior-posterior sway range, sway area, and sway velocity, were assessed in eyes-open and eyes-closed conditions. Adjusted linear regressions were used to assess relationships between posturography and BBS score. Mean BBS score was 50.4±5.3. In eyes-open conditions, posturography and BBS score were not significantly associated. In eyes-closed conditions, better BBS score was significantly associated with lower sway area (ß=-0.91; P =0.006). Better scores of BBS items involving turning and reduced base of support were associated with greater eyes-closed sway area. Posturography in the more challenging eyes-closed condition may predict functional balance deficits in AD patients.

OBJECTIVE: To describe iatrogenic laryngeal injury and identify its risk factors in recurrent respiratory papillomatosis (RRP) patients receiving surgical care. STUDY DESIGN: Case-control. SETTING: Tertiary care academic hospital in a metropolitan area. METHODS: Charts of patients with RRP seen at our institution from January 2002 to December 2022 were reviewed. Patients were separated into 2 cohorts based upon whether they experienced any form of iatrogenic laryngeal injury-including anterior commissure synechiae, vocal cord scar, reduced vocal fold pliability, vocal fold motion impairment, and glottic and/or subglottic stenosis. Adjusted logistic regressions were performed to identify factors associated with iatrogenic laryngeal injury. RESULTS: Of 199 RRP patients, 133 (66.8%) had identifiable iatrogenic laryngeal injury. The most common injuries were anterior commissure synechiae (n = 67; 50.4%) and reduced vocal fold pliability (n = 54; 40.6%). On a multivariate logistic regression, patients with diabetes mellitus (adjusted odds ratio [aOR] [95% confidence interval [CI]]: 2.99 [1.02, 8.79]; P = .04) and who received at least 10 surgeries lifetime (aOR [95% CI]: 14.47 [1.70, 123.19]; P = .01) were at increased risk for iatrogenic laryngeal injury, whereas receiving less than 5 surgeries (aOR [95% CI]: 0.21 [0.09, 0.51]; P < .001) was found to be protective. When treating the lifetime number of surgeries as a continuous variable, a greater number of surgeries was a significant risk factor for iatrogenic laryngeal injury (aOR [95% CI]: 1.32 [1.14, 1.53]; P < .001). CONCLUSION: These results suggest the importance of strict glucose control for diabetic patients receiving RRP surgical care, and emphasize the clinical need to identify medical therapies to decrease RRP surgical frequency for patients.

OBJECTIVE: To narrow knowledge gaps in the pathophysiology of idiopathic subglottic stenosis (iSGS) through comparison of a murine subglottic stenosis model with iSGS. STUDY DESIGN: In vivo animal study. SETTING: Academic institution. METHODS: Murine samples/measurements were obtained from mice that underwent chemomechanical injury with a wire brush and bleomycin. Human samples/measurements were obtained from iSGS patients. Anatomic, physiologic, and epithelial molecular data were collected using histology, human peak expiratory flow (PEF) and murine airway conductance, gene expression analysis with quantitative polymerase chain reaction, and protein analysis with quantitative immunohistochemistry. RESULTS: Anatomic patterns of scars at the subglottis and proximal trachea seen in the murine model are similar to iSGS patients. Subglottic stenosis (SGS) mice had a decrease (P = .0194) in airway conductance compared to healthy controls, similar to a decrease (P = .0001) in predilation PEF versus postdilation in iSGS patients. There was decreased epithelial gene expression of E-cadherin (ECAD) (P < 0.01), occludin (OCLN) (P < .01), and cytokeratin-5 (CK5) (P < .05) and protein expression of ECAD (H/M: P < .001), OCLN (H: P < 0.05, M: P < .001), and CK5 (H: P < .001, M: P < .01) in murine SGS and iSGS versus controls. CONCLUSION: The murine SGS model shows anatomic, physiologic, and molecular congruency with human iSGS, making it a reasonable model to investigate iSGS. The molecular similarities in epithelial barrier dysfunction suggest it may best be suited to explore epithelial mechanisms of iSGS and therapies directed at epithelial reconstitution. This model provides a foundation to collect data that will improve understanding of iSGS, and, ultimately, translate into more accurate animal models for future use.

OBJECTIVES: Animal models for laryngotracheal stenosis (LTS) are critical to understand underlying mechanisms and study new therapies. Current animal models for LTS are limited by small airway sizes compared to human. The objective of this study was to develop and validate a novel, large animal ovine model for LTS. METHODS: Sheep underwent either bleomycin-coated polypropylene brush injury to the subglottis (n = 6) or airway stent placement (n = 2) via suspension microlaryngoscopy. Laryngotracheal complexes were harvested 4 weeks following injury or stent placement. For the airway injury group, biopsies (n = 3 at each site) were collected of tracheal scar and distal normal regions, and analyzed for fibrotic gene expression. Lamina propria (LP) thickness was compared between injured and normal areas of trachea. RESULTS: No mortality occurred in sheep undergoing airway injury or stent placement. There was no migration of tracheal stents. After protocol optimization, LP thickness was significantly increased in injured trachea (Sheep #3: 529.0 vs. 850.8 um; Sheep #4: 933.0 vs. 1693.2 um; Sheep #5: 743.7 vs. 1378.4 um; Sheep #6: 305.7 vs. 2257.6 um). A significant 62-fold, 20-fold, 16-fold, 16-fold, and 9-fold change of COL1, COL3, COL5, FN1, and TGFB1 was observed in injured scar specimen relative to unaffected airway, respectively. CONCLUSION: An ovine LTS model produces histologic and transcriptional changes consistent with fibrosis seen in human LTS. Airway stent placement in this model is safe and feasible. This large airway model is a reliable and reproducible method to assess the efficacy of novel LTS therapies prior to clinical translation. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.
RESUMO
OBJECTIVES: Medical therapies to limit disease recurrence are critically needed for recurrent respiratory papillomatosis (RRP). Systemic bevacizumab is emerging as an exciting adjuvant therapy toward this end, but uptake has been poor due to the lack of experience and awareness of best prescribing practices. The objective of this study was to describe a single tertiary care academic medical center's experience using systemic bevacizumab for the treatment of RRP. METHODS: A retrospective review was performed to identify patients with RRP on systemic bevacizumab. Demographic and clinical characteristics, findings on imaging reports, and disease response at all anatomic subsites involved in papilloma were documented. RESULTS: Of the 17 RRP patients on systemic bevacizumab, 9 (52.9%) were male, and 12 (70.6%) were diagnosed with juvenile-onset RRP. The total lifetime number of surgeries was high, with more than half (n = 9; 52.9%) undergoing more than 50 surgeries. Following induction of systemic bevacizumab, a significant reduction in patients with laryngeal (n = 15; 94.1% vs. n = 7; 41.2%, p < 0.001) and tracheal (n = 11; 64.7% vs. n = 5; 29.4%, p = 0.04) RRP was noted. Surgical frequency was significantly lower following systemic bevacizumab (2.5 vs. 0.5 surgeries per year; p < 0.001). The most common complications were new-onset hypertension (n = 4; 23.5%) and proteinuria (n = 5; 29.4%). CONCLUSION: Systemic bevacizumab is effective in reducing the number of surgeries needed for RRP while exhibiting a relatively safe complication profile. Papillomas in the larynx and trachea are most responsive to systemic bevacizumab, while pulmonary RRP is most likely to exhibit a partial-to-stable response.

OBJECTIVE: To present a comprehensive flow cytometry panel for idiopathic subglottic stenosis (iSGS). STUDY DESIGN: Controlled ex vivo cohort study. SETTING: Tertiary care academic hospital in a metropolitan area. METHODS: Flow cytometry and single-cell RNA sequencing were performed on 9 paired normal and scar tissue samples from iSGS patients. Flow cytometry was used to assess the presence of myeloid (CD11b, CD14, CD15, Siglec8), lymphoid (CD3, CD4, CD8, gamma delta [γδ], FOXP3), endothelial (CD31), fibroblast (CD90, SMA), and epithelial (CD326, CK5) markers. RESULTS: On flow cytometry, iSGS scar is characterized by an increased presence of myeloid, lymphoid, endothelial, and fibroblast cell types, but a decreased presence of epithelial cells. In the myeloid lineage, iSGS scar samples demonstrated increased CD11b+ monocytes (P < .001), Siglec8+ eosinophils (P = .03), and CD14+ monocytes (P = .02). In the lymphoid lineage, iSGS scar demonstrated increased CD3+ T-cells (P < .001), CD4+ helper T-cells (P < .001), γδ+ T-cells (P < .001), and FOXP3+ regulatory T-cells (P = .002). iSGS scar exhibited specific increases in CD90+ (P = .04) and SMA+ (P < .001) fibroblasts but decreased CD326+ (E-cadherin) epithelial cells (P = .01) relative to normal samples. CONCLUSION: We present a comprehensive flow cytometry panel for iSGS. This flow panel may serve as a common platform among airway scientists to elucidate the cellular mechanisms underpinning iSGS and other upper airway pathologies. Scar iSGS samples demonstrate a distinct cellular profile relative to normal iSGS specimens, exhibiting increased fibroblast, endothelial, and inflammatory cell types but decreased epithelium.
RESUMO
OBJECTIVES: Pulmonary papillomatosis is a rare but severe manifestation of recurrent respiratory papillomatosis (RRP). Efficacy data of systemic bevacizumab for pulmonary RRP are limited. This study's objective was to characterize disease response of pulmonary RRP to systemic bevacizumab. METHODS: A retrospective review was performed to identify patients with pulmonary RRP seen at three medical institutions. Clinical symptoms, CT findings, and disease response were compared before and after initiation of systemic bevacizumab therapy. Disease response was categorized as complete response, partial response, stabilization, or progression for each subsite involved by papilloma. RESULTS: Of the 12 pulmonary RRP patients treated with systemic bevacizumab, 4 (33.3%) were male, and 11 (91.7%) were juvenile-onset RRP patients. All presented with laryngeal, tracheal, and pulmonary RRP. The median (range) age at first bevacizumab infusion was 48.1 (19.5-70.2) years. Progression to pulmonary malignancy was identified in 3 (25.0%) patients, 2 before initiation of and 1 after complete cessation of bevacizumab therapy. Clinical symptoms such as dyspnea (75.0% vs. 25.0%; p = 0.01) and dysphagia and/or odynophagia (33.3 vs. 0.0%; p = 0.03) were significantly decreased following bevacizumab therapy. Compared with pre-treatment baseline, 9 (75.0%) patients experienced a stable-to-partial response in the lungs to systemic bevacizumab, and 10 (83.3%) experienced partial-to-complete responses in the larynx and trachea. CONCLUSION: Systemic bevacizumab is effective in stabilizing progression in even the most severe cases of RRP, with both a dramatic reduction in laryngeal and tracheal disease as well as a stable-to-partial response of pulmonary involvement in a majority of patients.

OBJECTIVES: Quality of life studies in recurrent respiratory papillomatosis (RRP) have traditionally relied upon clinician-designed survey instruments. This study's objective is to report quality of life outcomes from a patient-designed questionnaire. METHODS: Patients who provided health information and completed a quality of life questionnaire were identified from the RRPF-CoRDS patient registry. Demographic, clinical, and quality of life measures were collected. Means and standard deviations were calculated for continuous data, and frequencies and percentages were calculated for categorical data. Outcomes for patients with juvenile-onset RRP (JORRP) and adult-onset RRP (AORRP) were compared using Student's t-tests for continuous data and χ2 analyses for categorical data. RESULTS: Seventy-three patients with RRP were identified (JORRP: 32; AORRP: 41). Common clinical symptoms included raspy voice (78.1%) and dyspnea (61.6%). The majority (97.3%) of patients reported feeling debilitated by their diagnosis, and 94.5% of patients reported avoiding participation in career and/or social activities due to their voice quality. Due to their RRP, 65.7% reported missing at least five work days each month. Social anxiety was reported in 79.5% of patients, though only 28.8% of the cohort reported utilizing mental health services. The median (range) lifetime number of surgeries received was 20 (1 - 300). Most patients (57.5%) reported paying at least 5% of their annual income towards RRP-related medical care. CONCLUSION: RRP presents high mental and fiscal burden. Our results highlight data from a quality of life questionnaire designed by RRP patients, and may help to elucidate potential disconnects between what clinicians and RRP patients consider most impactful.

Recurrent croup is a common clinical entity afflicting the pediatric population, but is not well-characterized in the literature. We describe the largest series of recurrent croup in North America from a single tertiary care academic center, and differentiate subpopulations based on demographic characteristics and clinical presentation. We identified 114 patients for inclusion. Common symptoms included barky cough (86.0%) and inspiratory stridor (60.5%). Many (26.3%) experienced full symptom resolution within a day, and 41.2% reported onset of symptoms at any time of the day. Male patients had a higher number of prior croup episodes at presentation compared with female patients (mean of 9.8 ± 8.0 in males vs 6.6 ± 4.8 in females, P = .03). On multivariate regression, racial/ethnic minority patients were at higher risk for dyspnea (odds ratio [OR]: 58.6; 95% confidence interval [CI]: 7.2-475.4) and upper respiratory infection prodrome (OR: 7.6; 95% CI: 1.6-35.3) compared with non-Hispanic white patients.

OBJECTIVES: Optimal vocal care for transgender patients necessitates regular follow-up. Factors associated with loss of follow-up in voice patients have never been investigated. In this study, we report a case series of transgender patients seeking vocal care at our institution and compare those who were and were not lost to follow-up. METHODS: Charts of transgender patients diagnosed with gender dysphoria who sought vocal care at our institution from January 2018 through May 2022 were reviewed. A chronological timeline of each patient's care at our vocal clinic was recorded. Loss of follow-up was defined as instances in which patients were not yet satisfied with their vocal outcomes and expressed interest in scheduling a subsequent visit but had not yet done so. Logistic regressions were performed to identify factors associated with loss of follow-up. RESULTS: Of 73 patients identified, 59 (80.8%) were assigned male at birth, and 72 (98.6%) were non-Hispanic White. Loss of follow-up occurred in 35 (47.9%) patients. Patients who received vocal surgery were significantly less likely to be lost to follow-up (OR: 0.16 (0.03, 0.79); p = 0.03). The availability of telemedicine options for vocal care was protective against loss of follow-up (OR: 0.09 (0.02, 0.44); p = 0.003). Patients who received other non-voice gender-affirming treatments concomitant to their vocal care were more likely to be lost to follow-up (OR: 4.44 (1.35, 14.59); p = 0.01). CONCLUSION: Loss of follow-up in transgender patients receiving vocal care is common. Providing telemedicine options and encouraging patients to complete vocal care prior to or after receiving other non-voice gender-affirming treatments may help increase rates of follow-up.

BACKGROUND: Whether the total number of compressive vessels in trigeminal neuralgia (TN) affects outcomes after microvascular decompression (MVD) is unknown. OBJECTIVE: To investigate whether the number of compressive vessels is associated with outcomes after MVD. METHODS: We retrospectively reviewed all patients with TN who underwent MVDs at our institution from 2007 to 2020. The number and identity of compressive vessels on the trigeminal nerve were recorded. Preoperative and postoperative pain and numbness Barrow Neurological Institute scores were compared. Factors associated with pain recurrence were assessed using survival analyses and multivariate regressions. RESULTS: We identified 496 patients with a single vessel and 381 patients with multiple vessels compressing the trigeminal nerve. Compared with patients with a single compressive vessel, patients with multiple sources of compression exhibited increased Barrow Neurological Institute pain scores preoperatively ( P = .01). In addition, pain recurrence was more frequent ( P < .001) and occurred after a significantly shorter pain-free duration ( P < .001) for the multiple compression group. Using multivariate ordinal regression, a greater number of arteries ( P = .03) and veins ( P = .03) were both significantly associated with higher pain scores at final follow-up. Furthermore, the number of arteries ( P = .01) and of veins ( P = .01) was significantly associated with a higher risk for pain recurrence. CONCLUSION: TN patients with a single compressive vessel exhibited better pain outcomes after an MVD. Patients with multiple compressive vessels exhibited higher pain scores preoperatively and incurred a higher risk for pain recurrence, which occurred after a shorter pain-free interval compared with the single compression cohort.

BACKGROUND: Microvascular decompression (MVD) using a retrosigmoid approach is a highly effective, open-surgical procedure for neurovascular conflict in the posterior fossa, although there is a risk of postoperative cerebrospinal fluid (CSF) leak. OBJECTIVE: To identify factors associated with postoperative CSF leakage after MVD. METHODS: We retrospectively reviewed all patients who underwent MVDs at our institution from 2007 to 2020. Patient demographics, clinical diagnoses, and procedural characteristics were recorded and compared. Factors leading to CSF leak were analyzed using χ 2 , univariate, and multivariate regression. RESULTS: Of 1011 patients who underwent MVDs, 37 (3.7%) presented with postoperative CSF leaks. In univariate analysis, the use of Cranios/Norian to obliterate the air cells was protective against CSF leak ( P = .01). Craniotomies ( P = .002), the use of dural substitutes such as Durepair ( P = .04), dural onlays such as DuraGen ( P = .04), muscle/fascia ( P = .03), and titanium mesh cranioplasty >5 cm ( P = .03) were associated with CSF leak. On multivariate analysis, only the presence of craniotomies ( P = .04) and nonprimary dural closure ( P = .03) were significant risk factors for CSF leak. When excluding the 34 (3.4%) patients who underwent a craniotomy, the lack of primary dural closure still remained significantly associated with postoperative CSF leak ( P = .04). CONCLUSION: Our results represent one of the largest series of posterior fossa surgeries for a uniform indication in North America. Our study demonstrates increased risk for postoperative CSF leak when craniotomies are performed and when primary dural closure is not established. Given the small sample of patients who received a craniotomy, however, future studies corroborating this finding should be performed.

BACKGROUND: Microvascular decompressions (MVDs) are effective open-surgical procedures for trigeminal neuralgia (TN). Intraoperative management of compressive veins may include either venous transposition or coagulation. Although both are generally considered safe, which technique results in optimal postoperative outcomes remains unclear. OBJECTIVE: To compare postoperative pain and numbness outcomes after an MVD in patients with TN of exclusive venous compression. METHODS: We retrospectively reviewed all patients with TN who underwent MVDs at our institution from 2007 to 2020. Patients with TN of pure venous compression were identified using MRI imaging, which was subsequently confirmed intraoperatively. Patient demographics, procedural characteristics, and postoperative pain and numbness scores were recorded and compared. Factors associated with pain recurrence were assessed using survival analyses and multivariate regressions. RESULTS: We identified 181 patients who presented with TN of pure venous compression. Using a multivariate linear regression, adjusted for age, sex, and presence of multiple sclerosis, use of venous transposition vs coagulation was not significantly associated with the Barrow Neurological Institute pain score at final follow-up, although venous transposition was significantly predictive of a worse postoperative Barrow Neurological Institute numbness score ( P = .003). Using a Kaplan-Meier survival analysis and a multivariate Cox proportional hazards regression, respectively, venous transposition was significantly associated with faster ( P = .01) as well as higher risk for pain recurrence ( P = .01). CONCLUSION: The use of venous coagulation during an MVD is associated with better postoperative pain and numbness outcomes. The results of our study may help inform preoperative patient counseling and surgical management for TN cases that involve pure venous compression.

OBJECTIVE: The objective of this study was to characterize the risk factors for posterior glottic injury (PGI) in patients with coronavirus disease 2019 (COVID-19) who underwent prolonged intubation. STUDY DESIGN: This was a case-control study designed to assess the risk factors associated with development of PGI in COVID-19 patients who underwent prolonged intubation. SETTING: This single-center study was conducted at a tertiary care academic hospital in a metropolitan area. METHODS: We retrospectively reviewed patients who underwent prolonged intubation (≥7 days) for COVID-19 and compared those with PGI to those without. Patient demographics, comorbidities, and intubation characteristics were compared. Factors associated with PGI development among COVID-19 patients were assessed using multivariate regression. RESULTS: We identified 56 patients who presented with PGI following prolonged intubation for COVID-19 and 60 control patients who underwent prolonged intubation for COVID-19 but did not develop PGI. On univariate analyses, the number of reintubations due to failed extubation efforts was significantly associated with development of PGI (odds ratio [OR], 2.9; 95% CI, 1.4-6.2). On multivariate analyses, patients with cardiovascular disease (OR, 3.3; 95% CI, 1.2-9.0); non-COVID-19 respiratory illnesses, which included obstructive sleep apnea and asthma (OR, 5.9; 95% CI, 2.0-17.8); and diabetes mellitus (OR, 11.6; 95% CI, 3.7-36.6) were more likely to develop PGI. CONCLUSION: Our results represent the largest case-control study investigating risk factors for PGI in the setting of prolonged intubation specific to COVID-19. Our study suggests a significant role of comorbidities associated with poor wound healing with development of PGI.

OBJECTIVE: Pain outcomes by race in trigeminal neuralgia (TN) are not well investigated. The authors aimed to compare microvascular decompression (MVD) outcomes in TN patients on the basis of self-identified race. METHODS: The authors retrospectively reviewed all patients with TN who underwent MVD at their institution from 2007 to 2020. Each patient's self-reported race was recorded, and Barrow Neurological Institute (BNI) scores for pain and numbness were compared. Factors associated with pain recurrence were assessed using survival analyses and multivariate regressions. RESULTS: Of 1011 patients, 925 reported their racial demographic characteristics, and patients who identified as Native American or American Indian and Native Hawaiian or Pacific Islander were excluded due to small sample sizes. Of the resulting 921 patients, 697 (75.7%) patients identified as White, 108 (11.7%) as Black or African American, 39 (4.2%) as Asian, and 77 (8.4%) as other. Compared with White patients, Black TN patients were more likely to present with type 1 TN (p = 0.02). At final follow-up, the mean BNI pain score of Black patients was significantly higher (p < 0.001) compared with that of White patients, although pain scores did not differ preoperatively. The adjusted multivariate ordinal regression model showed that Black patients were associated with higher BNI pain scores at final follow-up (p = 0.01). Furthermore, compared with White patients, Black patients were at increased risk for postoperative pain recurrence (p = 0.04), which additionally occurred after a shorter median pain-free duration (p = 0.03). CONCLUSIONS: TN patients who identify as Black or African American exhibit worse postoperative pain outcomes after MVD compared with White patients. Future studies investigating the factors driving these racial differences are warranted.

BACKGROUND AND OBJECTIVES: Although the association between multiple sclerosis and trigeminal neuralgia (TN) is well established, little is known about TN pain characteristics and postoperative pain outcomes after microvascular decompression (MVD) in patients with TN and other autoimmune diseases. In this study, we aim to describe presenting characteristics and postoperative outcomes in patients with concomitant TN and autoimmune disease who underwent an MVD. METHODS: A retrospective review of all patients who underwent an MVD at our institution between 2007 and 2020 was conducted. The presence and type of autoimmune disease were recorded for each patient. Patient demographics, comorbidities, clinical characteristics, postoperative Barrow Neurological Institute (BNI) pain and numbness scores, and recurrence data were compared between groups. RESULTS: Of the 885 patients with TN identified, 32 (3.6%) were found to have concomitant autoimmune disease. Type 2 TN was more common in the autoimmune cohort ( P = .01). On multivariate analysis, concomitant autoimmune disease, younger age, and female sex were found to be significantly associated with higher postoperative BNI score ( P = .04, <0.001, and <0.001, respectively). In addition, patients with autoimmune disease were more likely to experience significant pain recurrence ( P = .009) and had shorter time to recurrence on Kaplan-Meier analysis ( P = .047), although this relationship was attenuated on multivariate Cox proportional hazards regression. CONCLUSION: Patients with concomitant TN and autoimmune disease were more likely to have Type 2 TN, had worse postoperative BNI pain scores at the final follow-up after MVD, and were more likely to experience recurrent pain than patients with TN alone. These findings may influence postoperative pain management decisions for these patients and support a possible role for neuroinflammation in TN pain.

Objectives: To develop a novel remote head impulse test (rHIT), and to provide preliminary data validating the rHIT vestibular-ocular reflex (VOR) gains against the in-clinic vHIT. Methods: A convenience sample of 10 patients referred for vestibular assessment at our institution was recruited. In-clinic vHIT was used to quantify lateral VOR gains. Patients subsequently underwent an rHIT protocol, whereby patients performed active, lateral head rotations while their eyes and heads were recorded using a laptop camera and video-conferencing software. The vHIT and rHIT VOR gains were compared using paired t-tests, and a Pearson correlation coefficient between the gains was calculated. Absolute accuracy, sensitivity, and specificity of the rHIT were additionally calculated. Results: Of the 10 patients recruited, 4 were male, and the average ± standard deviation (SD) age was 61.4 ± 15.3 years. As determined by the vHIT, 2 patients had normal bilateral VOR gains, 6 with unilateral vestibular hypofunction, and 2 with bilateral vestibular hypofunction. The correlation between the rHIT and vHIT gains was 0.73 (p < .001). The rHIT exhibited an absolute accuracy of 75.0%, sensitivity of 70.0%, and specificity of 80.0%. When ears had a vHIT VOR gain less than 0.40, the rHIT exhibited 100.0% accuracy. Conversely, 60.0% of deficient ears with vHIT VOR gains greater than 0.40 were incorrectly categorized by the rHIT. Conclusion: The rHIT may be better suited for detecting more severe vestibular deficiencies. Future iterations of the rHIT should aim to increase the video frame-rate capabilities to detect subtler VOR impairments. Level of Evidence: 4.
RESUMO
PURPOSE: Sequential onset of bilateral trigeminal neuralgia (TN) is rare and not well-described in the literature. The objective of this study was to characterize demographic, clinical, and procedural characteristics of patients with sequential onset bilateral TN. METHODS: We retrospectively reviewed patients presenting with sequential onset bilateral TN at our institution from 2007 to 2020. Patient demographics, clinical diagnoses, pain outcomes, and procedural characteristics were recorded and compared. Factors associated with pain recurrence were assessed using survival analyses and multivariate regressions. RESULTS: We identified 34 patients who presented with sequential onset bilateral TN. The average age of onset for the index case was 49.9 ± 15.5 years, and 58.0 ± 16.8 years for the contralateral case. In total for our cohort, 91 surgical procedures were performed for the index case, and 70 for the contralateral case. With each additional surgical intervention, pain-free survival was more likely to decrease, p = 0.05. When controlled for order of intervention, glycerin rhizotomy (p = 0.01) and glycerin-radiofrequency rhizotomy (p = 0.05) were more likely associated with pain recurrence compared to microvascular decompression. While pain outcomes were significantly decreased in our cohort at final follow-up, 82.4% of patients were still dependent on medication for pain management after an average of 5.03 ± 7.74 years. CONCLUSION: Our results represent one of the largest series of sequential onset bilateral TN in North America. Our study demonstrates the high treatment burden and chronicity of pain encountered in this population.

BACKGROUND: Trigeminal neuralgia (TN) is more prevalent among women. However, while microvascular decompression (MVD) is the most effective long-term surgical treatment for TN, it is unclear whether it is equally efficacious for men and women. We sought to characterize the relationship between sex and pain outcomes following MVD for TN. METHODS: From 2007 to 2020, 938 unilateral TN patients were treated with MVD at our institution. Patient demographics, clinical characteristics, operative features, and pain outcomes were recorded. Differences between men and women were analyzed via t-test and chi-squared analyses. A multivariate ordinal regression was used to establish significant predictors of pain outcome. Differences in time to pain recurrence were assessed via Cox proportional hazards and Kaplan-Meier nonparametric survival analysis. RESULTS: A majority (67%) of the 938 patients analyzed were female. Men and women presented with similar preoperative pain severity (P = 0.17). Female sex (P = 0.048) and younger age (P = 0.03) were independently associated with worsened Barrow Neurological Institute pain scores at 3-month follow-up on multivariate analysis. Women were also more likely to experience recurrence than men (P = 0.01), and time to recurrence was shorter among women (P = 0.02). Only female sex was independently associated with increased risk of postoperative pain recurrence on multivariate Cox proportional hazards regression (P = 0.01). CONCLUSIONS: Female TN patients undergoing MVD had worse pain outcomes, more frequent pain recurrence, and shorter time to recurrence. Our results indicate a sex-specific dimorphism in response to MVD among TN patients.

OBJECTIVES: While patients with concomitant trigeminal neuralgia (TN) and multiple sclerosis (MS) are understood to experience a more intractable pain phenotype, whether TN pain outcomes differ by the presenting MS subtype is not well characterized. This study's objective is to compare post-operative pain and numbness outcomes following microvascular decompression (MVD) in TN patients with either relapsing-remitting MS (RRMS) or progressive MS. METHODS: We retrospectively reviewed all TN patients who underwent MVDs at our institution from 2007 to 2020. Of the 1044 patients reviewed, 45 (4.3%) patients with MS were identified. Patient demographics, procedural characteristics, and post-operative pain and numbness scores were recorded and compared. Factors associated with pain recurrence were assessed using survival analyses and multivariate regressions. RESULTS: Of the resulting 45 MS patients, 34 (75.6%) patients presented with the RRMS subtype, whereas 11 (24.4%) patients exhibited progressive MS. Using an adjusted multivariate ordinal regression, the subtype of MS was not significantly associated with the Barrow Neurological Institute (BNI) pain score at final follow-up. Using a Kaplan-Meier survival analysis and a multivariate Cox proportional hazards regression, respectively, RRMS was significantly associated with a shorter post-operative pain-free interval (p = 0.04) as well as a greater risk for pain recurrence (p = 0.02). CONCLUSIONS: Although the degree of pain at final follow-up may not differ, RRMS patients are at increased risk for pain recurrence following MVD for TN. These results align with a growing understanding that neuroinflammation may play a significant role in TN pain.
