RESUMO
Background An increasing number of nonbinary patients are receiving gender-affirming procedures due to improved access to care. However, the preferred treatments for nonbinary patients are underdescribed. The purpose of this study was to investigate the goals and treatments of nonbinary patients. Methods A retrospective study of patients who self-identified as nonbinary from our institutional Gender Health Program was conducted. Patient demographics, clinical characteristics, surgical goals, and operative variables were analyzed. Results Of the 375 patients with gender dysphoria, 67 (18%) were nonbinary. Over half of the nonbinary patients were assigned male at birth ( n = 57, 85%) and nearly half preferred the gender pronoun they/them/theirs ( n = 33, 49%). A total of 44 patients (66%) received hormone therapy for an average of 2.5 ± 3.6 years, primarily estrogen ( n = 39). Most patients ( n = 46, 69%) received or are interested in gender-affirming surgery, of which, almost half were previously on hormone therapy ( n = 32, 48%). The most common surgeries completed or desired were facial feminization surgery ( n = 15, 22%), vaginoplasty ( n = 15, 22%), mastectomy ( n = 11, 16%), and orchiectomy ( n = 9, 13%). Nonbinary patients who were assigned male at birth (NB-AMAB) were more often treated with hormones compared to nonbinary patients assigned female at birth (NB-AFAB) (72% vs. 30%, p = 0.010). Conversely, patients who were AFAB were more likely to complete or desire surgical intervention than those who were AMAB (100% vs. 63.0%, p < 0.021). Conclusion Majority of nonbinary patients were assigned male at birth. NB-AFAB patients all underwent surgical treatment, whereas NB-AMAB patients were predominantly treated with hormone therapy.
RESUMO
Background: Traditionally, plastic surgeons have performed palatoplasties using mucoperiosteal flaps with lateral incisions that are medial to the alveolar ridge. However, narrow flaps can cause limitations in some cases. To construct larger and wider flaps and minimize exposed bone after closure, we propose a novel technique that entails creating the lateral incisions at the top of the alveolar ridge, instead of the base of the alveolar ridge, to capture more tissue when repairing the hard palate. Methods: A retrospective chart review was conducted for patients undergoing cleft palate repair with the aforementioned technique. Information collected included basic demographic and diagnostic factors related to cleft palate deformity and history of previous facial surgeries. Operative report details and postoperative complications were analyzed. Results: Nineteen patients with hard palate clefts were included in the analysis, with the majority being women (68%). There was a balanced representation of patients with Veau classifications of II (47%) and III (42%). The majority of patients had an isolated cleft palate (74%) and incomplete deformity (63%), with no other craniofacial deformities. One (5%) had postoperative self-limited oronasal fistula managed conservatively. Conclusions: We present a novel approach for repairing cleft palate deformities by extending the lateral incision to the top of the alveolar ridge to create larger mucosal flaps. Further longitudinal studies are needed to evaluate how this unique approach compares to traditional methods-with respect to impact on maxillary growth processes, requirement for subsequent surgeries beyond two years of follow-up, and ultimately normalized speech over time.
RESUMO
INTRODUCTION: Orofacial clefts are the most common craniofacial anomaly observed in the United States. Permitted by recent advancements in anesthesia and multimodal pain management, there has been a trend toward outpatient cleft lip repair to alleviate hospital burden and minimize healthcare costs. The purpose of this study was to compare complication rates between outpatient and inpatient cleft lip repair from large national samples as well as identify preoperative factors that predicted discharge status. METHODS: The National Surgical Quality Improvement Program database for pediatrics was used to analyze 30-day outcomes for all patients undergoing cleft lip repair (CPT (current procedural terminology) code 40700) from 2012 to 2019. Complication rates were compared across 3 groups: same day discharge, next day discharge, and later discharge. Preoperative factors, including comorbidities and demographics, were analyzed to determine the impact of discharge date on complications as well as identify independent predictors of discharge timing and perioperative complications. RESULTS: A total of 6689 patients underwent primary cleft lip repair, with 16.8% discharging on day of surgery, and 72.4% discharging 1 day after surgery. Complication rates were statistically equivalent between same day and next day discharge. Preoperative factors predicting complication and postoperative admission included age <6âmonths and weight less than ten pounds at the time of surgery. Patients discharged after more than 1 day in the hospital had higher rates of complications as well as more preoperative comorbidities. CONCLUSIONS: Complication rates between same day and next day discharge are equivalent, suggesting that same day discharge is a safe option in select patients. Clinical judgment is critical in making these decisions.

ABSTRACT: The purpose of this study was to analyze the prevalence, diagnosis, and management of velopharyngeal insufficiency (VPI) in patients with craniofacial microsomia (CFM).Craniofacial microsomia patients 13âyears of age and above treated at 2 centers from 1997 to 2019 were reviewed retrospectively for demographics, prevalence of VPI, and management of VPI. Patients with isolated microtia were excluded. Comparisons were made between patients with and without VPI using chi-square and independent samples t tests.Among 68 patients with CFM (63.2% male, mean 20.7âyears of age), VPI was diagnosed in 19 patients (27.9%) at an average age of 7.2âyears old. Among the total cohort, 61 patients had isolated CFM, of which 12 (19.6%) were diagnosed with VPI. Of the patients with isolated CFM and VPI, 8 patients (66.7%) were recommended for nasoendoscopy, of which only 2 patients completed. Seven isolated CFM patients (58.3%) underwent speech therapy, whereas none received VPI surgery. In contrast, 7 patients were diagnosed with both CFM and cleft lip and/or palate (CL/P), all of whom had VPI and were recommended for nasoendoscopy, with 5 (71.4%) completing nasoendoscopy, 6 (85.7%) undergoing speech therapy, and 6 (85.7%) undergoing corrective VPI surgery. Overall, we demonstrated that VPI was present in 27.9% of all CFM patients. On subset analysis, VPI was diagnosed in 20% of patients with isolated CFM and 100% of patients with CFM and CL/P. In addition, despite clinical diagnosis of VPI, a sizeable proportion of isolated CFM patients did not undergo therapy or surgical interventions.

PURPOSE: Subcranial midface distraction is used to treat central midface deficiency in syndromic synostosis. Our aim was to determine which maxillary movements were associated with improvement in measures of obstructive sleep apnea. METHODS: This was a retrospective cohort study that reviewed patients with syndromic midface retrusion and documented sleep apnea who underwent subcranial midface distraction via either Le Fort 3 osteotomy or Le Fort 2 osteotomy with zygomatic repositioning. The predictor variables measured on cephalograms were the magnitude and direction of midface and mandibular movements. The primary outcome was the change in the apnea hypopnea index (AHI) from polysomnography before and after surgery. The secondary outcomes were volumes of upper airway containing bone spaces calculated from computed tomography scans. Data analysis included linear regression to estimate the effect of distraction vectors on bone space volumes and AHI changes. RESULTS: We included 18 patients primarily with Crouzon or Apert syndrome. The magnitude of distraction in a horizontal direction was the most significant factor for AHI improvement and primarily expanded the nasopharyngeal space, but with a smaller impact on the oral cavity space. Clockwise palate rotation was most influenced by a downward direction of distraction, with 24° below horizontal creating a neutral advancement. The greater the magnitude of advancement, the more likely a counterclockwise rotation was observed. CONCLUSIONS: Horizontal magnitude of advancement had the greatest impact on AHI improvement. Vertical lengthening and closure of anterior open bite deformities can be done without compromising airway results as long as total advancement is not compromised. Palate rotation is best controlled by a downward distraction vector, but counterclockwise rotation increases with greater advancement.

BACKGROUND: The authors' purpose was to quantify the change in unicoronal synostosis symmetry between presentation (time 0), after fronto-orbital advancement (time 1), and 2 years later (time 2). METHODS: Bandeau/orbital symmetry ratios and skull base/midface twists were measured on computed tomographic scans of consecutive isolated unicoronal synostosis patients. Comparisons were made across three time points and against normal controls. RESULTS: Forty-three unicoronal synostosis patients and 36 controls were included. The mean bandeau ratio (symmetry = 1) changed from 0.76 (time 0), to 1.13 (time 1), and then to 1.01 (time 2). The median bandeau ratio change from time 1 to time 2 was -9.1 percent and was impacted by the degree of time 1 asymmetry. The odds of a desired symmetric or overcorrected result (bandeau ratio > 1.0) at time 2 were increased in patients with less severe preoperative asymmetry (OR, 4.2; p = 0.04) and in those who obtained symmetry or overcorrection at surgery (OR, 4.9; p = 0.02). Craniofacial twist did not significantly change after surgery but decreased at time 2. Orbital height ratios were 1.08, 1.00, and then 1.02 at time 2, respectively. The orbital width ratio was not significantly impacted by surgery, remaining at 0.89 at time 2. CONCLUSIONS: Overcorrection of the unicoronal synostosis bandeau resulted in these patients being five times more likely to have a desired result at time 2. Patients with a more severe brow presentation were four times more likely to be asymmetric at time 2. Orbital height was improved, but attention should be directed at addressing orbital width. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

BACKGROUND: This study examines the potential contributions of environmental factors to variations in facial symmetry between identical twins. METHODS: Identical male and female twins were recruited from the Twins Days Festival in 2009 and 2010. Subjects independently completed a comprehensive questionnaire on their medical and personal history, and then posed for digital facial photography from several different angles. Eight facial features from these photographs were measured using Adobe Photoshop, and these facial features were then analyzed against survey responses between twins through multivariate regressions. RESULTS: A total of 147 pairs of identical twins were included. Twins who slept primarily prone had greater nasal midline deviation (p = 0.047) and oral commissure asymmetry (p = 0.027). Tooth extractions were significantly associated with canting of the plane of occlusion (p = 0.043), and use of dentures was associated with nasal midline deviation (p = 0.032) and oral commissure asymmetry (p = 0.007). Smoking was associated with canting of the plane of occlusion (p = 0.049) and upper eyelid ptosis (p = 0.023). Lastly, headaches were also associated with nasal midline deviation (p = 0.024). CONCLUSION: Exogenous factors such as prone sleep position, tooth extractions, dentures, and smoking are significant risk factors for facial asymmetry. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

BACKGROUND: This study was designed to report the details of the technique and assess the efficacy of surgical deactivation of temporal-triggered migraine headaches. It also examined the effect of surgical deactivation of temporal-triggered migraine headaches on migraine triggers and associated symptoms besides the pain. METHODS: The authors analyzed the charts of 246 patients receiving surgery for temporal-triggered migraine headaches by a single surgeon (B.G.) over a 10-year period, who were followed for at least 1 year. Median regression adjusted for age, sex, and follow-up time was used to determine postoperative reduction in temporal-specific migraine headache index, which is the product of frequency, severity, and duration. The association between individual symptom or trigger resolution and index value reduction was studied by logistic regression. Details of the surgical treatment are discussed. RESULTS: Eighty-five percent of patients reported a successful surgery (≥50 percent improvement of headache index) at least 12 months after surgery (mean follow-up, 3 years). Fifty-five percent reported complete elimination of temporal migraine headache. Symptoms resolving with successful site II surgery included nausea, photophobia, phonophobia, difficulty concentrating, vomiting, blurry vision, and eyelid ptosis (p < 0.05). Triggers resolving included letdown after stress, air travel, missed meals, bright lights, loud noises, fatigue, weather change, and certain smells (p < 0.05). CONCLUSIONS: Surgical deactivation of temporal-triggered migraine headaches is effective regardless of age, sex, or follow-up time. Successful site II surgery is associated with changes in specific symptoms and triggers. This information can assist in trigger avoidance and contribute to constellations used for temporal-triggered migraine headaches trigger-site identification. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: The purpose of this study was to investigate the potential contribution of environmental factors and testosterone on male alopecia. METHODS: Ninety-two identical male twins were recruited from 2009 to 2011. A comprehensive questionnaire was completed followed by the acquisition of sputum samples for testosterone analysis and standardized digital photography. Frontal, temporal, and vertex hair loss was assessed from these photographs. Hair loss was then correlated with survey responses and testosterone levels between twin pairs. Two independent, blinded observers also rated the photographs for hair thinning. RESULTS: Increased smoking duration (p < 0.001) and the presence of dandruff (p = 0.028) were significantly associated with increased frontal hair loss. Increased exercise duration (p = 0.002), consumption of more than four alcoholic drinks per week (p = 0.042), and increased money spent on hair loss products (p = 0.050) were all associated with increased temporal hair loss. Daily hat use (p = 0.050), higher body mass index (p = 0.012), and higher testosterone levels (p = 0.040) were associated with decreased temporal hair loss. Factors that were significantly associated with increased vertex hair loss included abstinence from alcohol consumption (p = 0.030), consumption of more than four alcoholic drinks per week (p = 0.004), increased smoking duration (p = 0.047), increased exercise duration (p = 0.050), and increased stress duration (p = 0.010). Lower body mass index, more children, increased caffeine consumption, history of skin disease, and abstinence from alcohol were significantly associated with increased hair thinning scores (p < 0.05). CONCLUSION: This study offers substantial evidence that exogenous factors may have a clinically significant impact on hair loss. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

BACKGROUND: The objective of the study was to determine whether botulinum toxin type A injections can serve as a prognosticator for migraine surgery success. METHODS: Patients who underwent migraine surgery from 2000 to 2010 by the senior author (B.G.) were reviewed. Patients were included if they had botulinum toxin type A injection before surgery; had completed postinjection, postsurgery Migraine Headache Questionnaires; and had at least 1-year follow-up. Outcome variables include patient demographics and Migraine Headache Index. Treatment success was defined as at least a 50 percent reduction in Migraine Headache Index. RESULTS: One hundred eighty-eight patients were included; 144 reported successful migraine headache reduction after injection (success group) and 44 did not (failure group). The groups were well matched for age, migraine headache characteristics, and number of surgical sites (p > 0.05). The surgery success rate was significantly higher in the success group overall (90.3 percent versus 72.3, p = 0.003), and in patients who reported botulinum toxin type A success and subsequent same-site surgery (97.9 percent versus 71.4 percent, p < 0.0001). Botulinum toxin type A success was prognostic for surgery success at the frontal trigger site (trigger site I) (92.5 percent versus 69.2 percent, p = 0.012), the temporal trigger site (trigger site II) (95.5 percent versus 73.3 percent, p = 0.005), and the occipital trigger site (trigger site IV) (95.9 percent versus 62.5 percent, p = 0.0003). Six patients had exclusively septum or turbinate (site III) surgery, and all failed injections. CONCLUSIONS: Positive botulinum toxin type A response is a significant predictor of migraine surgery success. When injections fail, nonmuscular abnormalities should be considered.

BACKGROUND: This study was designed to compare the success of occipital migraine headache surgery with and without occipital artery ligation. METHODS: The medical charts of 170 occipital migraine headache surgery recipients who fulfilled the study criteria were reviewed. Patients were divided into either the occipital artery resection group (one or both occipital arteries or its branches resected) or the control group (occipital arteries untouched). Preoperative and 12-month or more postoperative migraine frequency, duration, and intensity were analyzed. RESULTS: Fifty-five of the 170 patients met the inclusion criteria for the resection group; the remaining 115 were included in the control group. Of the 55 occipital artery resection patients, 44 (80.0 percent) had successful outcomes (≥ 50 percent reduction in occipital migraine headaches), with 21 (38.2 percent) experiencing elimination of migraines. Of the 115 control patients, 105 (91.3 percent) experienced success, with 74 (64.3 percent) experiencing elimination of occipital migraine headache. The control group had significantly higher success (p = 0.047) and elimination rates (p = 0.002) compared with the resection group. The control group had significantly greater mean reduction in migraine duration compared with the resection group (p = 0.008). CONCLUSIONS: Occipital artery resection significantly lowered the success of occipital migraine headache surgery. Greater occipital nerve decompression alone, without ligation of the occipital artery, significantly improved or eliminated occipital migraine headache in most patients. This suggests that routine removal of the occipital artery or its branches may not be necessary.

BACKGROUND: Müller's muscle-conjunctival resection is used to correct mild to moderate ptosis commonly encountered in the rejuvenation patient population. The authors examined its efficacy and analyzed variables that potentially affect outcomes. METHODS: Patients who underwent ptosis correction using Müller's muscle-conjunctival resection with greater than 10-month follow-up were included. Amount of ptosis reduction, eyelid symmetry, effects of concomitant facial aesthetic operations, and adverse outcomes were analyzed. Patients were grouped into medium- (<24 months after surgery) and long-term follow-up (>24 months) cohorts to determine whether outcomes changed over time. RESULTS: Forty patients with a mean follow-up of 28 months combined for a total of 70 resection operations. Resection significantly reduced ptosis by a mean of 1.48 ± 0.88 mm (p < 0.001), corresponding to 0.19 mm of eyelid elevation for every 1.0 mm of Müller's muscle resected. The procedure successfully corrected 84 percent of eyelids to within 0.5 mm and 94 percent to within 1.0 mm of normal eyelid position. On patients with asymmetric ptosis, it significantly improved eyelid symmetry to within 1.0 mm from 85 percent of patients before surgery to 95 percent after surgery, and to within 0.5 mm from 53 percent before surgery to 75 percent of patients after surgery (p = 0.036). Furthermore, the mean correction of ptosis was not significantly different between medium- (1.58 ± 0.93 mm) and long-term (1.32 ± 0.93 mm) follow-up patients (p = 0.258). CONCLUSIONS: Müller's muscle-conjunctival resection is an effective long-term solution to mild to moderate eyelid ptosis and asymmetry, and can be effectively performed concomitantly with other aesthetic facial procedures. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Appearance, aging, and disorders of the breast are multifactorial. There are intrinsic, patient-specific characteristics, such as breast growth during puberty and propensity for breast cancer, which are primarily inherited. There are also environmental factors, which can be potentially controlled. Monozygotic twins provide an excellent research opportunity to examine the role of extrinsic factors in subjects with identical genetic predispositions. OBJECTIVES: The authors investigate the role and significance of various environmental and acquired factors on breast aesthetics. METHODS: Identical female twins were recruited during the Twins Days Festival in Twinsburg, Ohio, in 2009 and 2010. After consent was obtained, enrolled subjects completed a comprehensive survey on their medical and personal history. Standardized digital photographs were taken by medical photographers. Sixteen aesthetic breast features were subjectively rated by 6 plastic surgery residents blinded to the survey results. These ratings were then analyzed against survey data to determine the significance of different exogenous factors on breast appearance. RESULTS: A total of 161 pairs of identical female twins (n = 322) with a mean (SD) age of 47.6 (14.5) years were recruited. Twins who moisturized their skin daily had significantly fewer rhytids (P = .002). Twins who received hormone replacement therapy after menopause had more attractive breast shape, size, projection, areolar shape, and areolar size (P < .03). However, twins who had a higher body mass index, greater number of pregnancies, and larger cup sizes had significantly less attractive breasts (P < .05). Twins who smoked cigarettes and consumed alcohol also had significantly less attractive breasts (P < .05). Twins who breastfed had less attractive areolar size and shape but better skin quality than their counterparts who never breastfed (P < .03). Finally, there was a significantly higher incidence of breast pain in twins who primarily slept on their sides compared with twins who primarily slept on their backs (P < .008). CONCLUSIONS: This study implicates several environmental factors that significantly affect the aesthetic quality of breasts.

BACKGROUND: In this study, the authors investigated the potential contribution of environmental factors and testosterone levels on androgenic alopecia in women. METHODS: Ninety-eight identical female twins were recruited from 2009 to 2011. Subjects were asked to complete a comprehensive questionnaire, provide a sputum sample for testosterone analysis, and pose for standardized digital photography. Frontal, temporal, and vertex hair loss were assessed from the photographs using Adobe Photoshop. Hair loss measures were then correlated with survey responses and testosterone levels between twin pairs. Two independent, blinded observers also rated the photographs for hair thinning. RESULTS: Factors associated with increased frontal hair loss included multiple marriages (p = 0.043); longer sleep duration (p = 0.011); higher severity of stress (p = 0.034); positive smoking history (p = 0.021); higher income (p = 0.023); absence of hat use (p = 0.017); and history of diabetes mellitus (p = 0.023), polycystic ovarian syndrome (p = 0.002), and hypertension (p = 0.001). Factors associated with increased temporal hair loss included divorce or separation (p = 0.034), multiple marriages (p = 0.040), more children (p = 0.005), longer sleep duration (p = 0.006), and history of diabetes mellitus (p = 0.008) and hypertension (p = 0.027). Lack of sun protection (p = 0.020), consuming less caffeine (p = 0.040), history of skin disease (p = 0.048), and lack of exercise (p = 0.012) were associated with increased vertex hair loss. Higher testosterone levels were associated with increased temporal and vertex hair loss patterns (p < 0.039). Increased stress, increased smoking, having more children, and having a history of hypertension and cancer were all associated with increased hair thinning (p < 0.05). CONCLUSION: This study implicates several environmental risk factors in the pathophysiology of female alopecia.

BACKGROUND: The auriculotemporal nerve has been identified as one of the peripheral trigger sites for migraine headaches. However, its distal course is poorly mapped following emergence from the parotid gland. In addition, a reliable anatomical landmark for locating the potential compression points along the course of the nerve during surgery has not been sufficiently described. METHODS: Twenty hemifaces on 10 fresh cadavers were dissected to trace the course of the auriculotemporal nerve from the inferior border of the zygomatic arch to its termination in the temporal scalp. The compression points were mapped and the distances were measured from the most anterosuperior point of the external auditory meatus, which was used as a fixed anatomical landmark. RESULTS: Three potential compression points along the course of the auriculotemporal nerve were identified. Compression points 1 and 2 corresponded to preauricular fascial bands. Compression point 1 was centered 13.1±5.9 mm anterior and 5.0±7.0 mm superior to the most anterosuperior point of the external auditory meatus, whereas compression point 2 was centered at 11.9±6.0 mm anterior and 17.2±10.4 mm superior to the most anterosuperior point of the external auditory meatus. A significant relationship was found between the auriculotemporal nerve and superficial temporal artery (compression point 3) in 80 percent of hemifaces, with three patterns of interaction: a single site of artery crossing over the nerve (62.5 percent), a helical intertwining relationship (18.8 percent), and nerve crossing over the artery (18.8 percent). CONCLUSION: Findings from this cadaver study provide information relevant to the operative localization of potential compression points along the auriculotemporal nerve.

BACKGROUND: This study was designed to compare the efficacy of the transpalpebral versus endoscopic approach to decompression of the supraorbital and supratrochlear nerves in patients with frontal migraine headaches. METHODS: The medical charts of 253 patients who underwent surgery for frontal migraine headaches were reviewed. These patients underwent either transpalpebral nerve decompression (n = 62) or endoscopic nerve decompression (n = 191). Preoperative and 12-month or greater postoperative migraine frequency, duration, and intensity were analyzed to determine the success of the surgeries. RESULTS: Forty-nine of 62 patients (79 percent) in the transpalpebral nerve decompression group and 170 of 191 patients (89 percent) who underwent endoscopic nerve decompression experienced a successful outcome (at least a 50 percent decrease in migraine frequency, duration, or intensity) after 1 year from surgery. Endoscopic nerve decompression had a significantly higher success rate than transpalpebral nerve decompression (p < 0.05). Thirty-two patients (52 percent) in the transpalpebral nerve decompression group and 128 patients (67 percent) who underwent endoscopic nerve decompression observed elimination of migraine headaches. The elimination rate was significantly higher in the endoscopic nerve decompression group than in the transpalpebral nerve decompression group (p < 0.03). CONCLUSION: Endoscopic nerve decompression was found to be more successful at reducing or eliminating frontal migraine headaches than transpalpebral nerve decompression and should be selected as the first choice whenever it is anatomically feasible. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BACKGROUND: This study was designed to assess whether preoperative trigger-site confirmation using botulinum toxin type A injections significantly improved migraine surgery outcomes. METHODS: The medical charts of 335 migraine surgery patients were reviewed. Patients who received stepwise diagnostic botulinum toxin type A injections were placed in the botulinum toxin type A group (n = 245). Patients who did not receive botulinum toxin type A or received only therapeutic botulinum toxin type A were placed in the control group (n = 90). The preoperative and 12-month postoperative migraine headache frequency, duration, and intensity were compared to determine the success of the operations. RESULTS: Seventy-two of 90 control patients (80 percent) experienced a significant improvement (a decrease of at least 50 percent in migraine headache frequency, duration, or intensity) at 12 months after surgery, with 29 (32 percent) reporting complete elimination. Of the 245 botulinum toxin type A patients, 207 (84 percent) experienced a significant improvement, with 89 (36 percent) experiencing complete elimination. The surgical success rate of the botulinum toxin type A group was not significantly higher than that of the control group (p = 0.33). CONCLUSIONS: Confirmation of trigger sites using botulinum toxin type A does not significantly improve the outcome of migraine surgery. Although botulinum toxin type A can be a useful diagnostic tool, this study demonstrates that there is no statistically significant difference between the injection of botulinum toxin type A and the use of a constellation of symptoms to identify trigger sites. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Body core cooling via the palm of a hand increases work volume during resistive exercise. We asked: (a) "Is there a correlation between elevated core temperatures and fatigue onset during resistive exercise?" and (b) "Does palm cooling between sets of resistive exercise affect strength and work volume training responses?" Core temperature was manipulated by 30-45 minutes of fixed load and duration treadmill exercise in the heat with or without palm cooling. Work volume was then assessed by 4 sets of fixed load bench press exercises. Core temperatures were reduced and work volumes increased after palm cooling (Control: Tes = 39.0 ± 0.1° C, 36 ± 7 reps vs. Cooling: Tes = 38.4 ± 0.2° C, 42 ± 7 reps, mean ± SD, n = 8, p < 0.001). In separate experiments, the impact of palm cooling on work volume and strength training responses were assessed. The participants completed biweekly bench press or pull-up exercises for multiple successive weeks. Palm cooling was applied for 3 minutes between sets of exercise. Over 3 weeks of bench press training, palm cooling increased work volume by 40% (vs. 13% with no treatment; n = 8, p < 0.05). Over 6 weeks of pull-up training, palm cooling increased work volume by 144% in pull-up experienced subjects (vs. 5% over 2 weeks with no treatment; n = 7, p < 0.001) and by 80% in pull-up naïve subjects (vs. 20% with no treatment; n = 11, p < 0.01). Strength (1 repetition maximum) increased 22% over 10 weeks of pyramid bench press training (4 weeks with no treatment followed by 6 weeks with palm cooling; n = 10, p < 0.001). These results verify previous observations about the effects of palm cooling on work volume, demonstrate a link between core temperature and fatigue onset during resistive exercise, and suggest a novel means for improving strength and work volume training responses.
