RESUMEN

Background: Autologous costal cartilage (ACC) and irradiated homologous costal cartilage (IHCC) are commonly used in septorhinoplasty when there is insufficient septal cartilage for grafting. Objective: To assess the surgical outcomes of patients who underwent septorhinoplasty with either ACC or IHCC as measured by rates of infection, resorption, warping, and revision rate. Methods: A retrospective analysis of patients who underwent rhinoplasty with ACC or IHCC at a single academic institution was performed. Demographic data, surgical details, antibiotic use, and outcomes, including surgical duration, infection, resorption, warping, and revision rate, were analyzed using Fisher's exact test, chi-squared test, and logistic regression. Results: One hundred forty-three patients were identified. The median age was 48 years (interquartile range: 35-57.5) and 62.2% (n = 89) were female, 61 patients (42.7%) underwent ACC, and 82 (57.3%) IHCC. Revision rate in both groups was similar (ACC = 14.8%, IHCC = 14.6%; p = 0.98). There was no difference in infection rate (ACC = 4.9%, IHCC = 3.7%; p = 0.71). Postoperative deformity and nasal obstruction were the most common indications for revision surgery. Surgical time was shorter with IHCC (p < 0.01). Mean follow-up time was 26.5 months (±25) for ACC, and 16 months (±12) for IHCC. Conclusions: ACC and IHCC are similar in terms of effectiveness and safety in septorhinoplasty.

RESUMEN

BACKGROUND: A subset of patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (HPV-OSCC) experience poor clinical outcomes. The authors of this report explored prognostic risk factors for overall survival (OS) and recurrence-free survival (RFS). METHODS: Patients with incident HPV-OSCC who received treatment at the Johns Hopkins Hospital between 1997 and 2008 and who had tissue available for HPV testing as well as demographic and clinicopathologic information (N = 176) were included. Tissue was tested for HPV by in situ hybridization (ISH) and/or p16 immunohistochemistry. Demographic and clinicopathologic information was extracted from medical records. RESULTS: In total, 157 of 176 patients (90%) with OSCC had HPV-associated disease (HPV-OSCC). In the patients with HPV-OSCC, the 3-year and 5-year OS rates were 93% (95% confidence interval [CI], 88%-98%) and 89% (95% CI, 81%-97%), respectively. Shorter survival was observed among older patients (hazard ratio [HR], 2.33 per 10-year increase; 95% CI, 1.05-5.16 per 10-year increase; P = .038), patients with advanced clinical T classification (HR, 5.78; 95% CI, 1.60-20.8; P = .007), and patients who were currently using tobacco (HR, 4.38; 95% CI, 1.07-18.0; P = .04). Disease recurrence was associated with advanced clinical T-classification (HR, 8.32; 95% CI, 3.06-23; P < .0001), current/former alcohol use (HR, 13; 95% CI, 1.33-120; P = .03), and unmarried status (HR, 3.28; 95% CI, 1.20-9.00; P = .02). Patients who remained recurrence free for 5 years had an 8.6% chance of recurrence by 10 years (1-sided 95% CI upper bound, 19%; P = .088). CONCLUSIONS: In this study, prognostic risk factors were identified for patients with HPV-OSCC. The observed recurrence rates between 5 years and 10 years after definitive therapy need to be validated in additional studies to determine whether extended cancer surveillance is warranted in this cancer population.

RESUMEN

Background: The Michigan Opioid Laws are legislation enacted between 2017 and 2018 as a strategy to combat the growing opioid crisis. Objective: To compare opioid prescription rates and morphine milligram equivalents (MMEs) of opioid prescribed to patients undergoing various facial plastic and reconstructive surgery (FPRS) procedures before, during, and after legislation enactment. Materials and Methods: This is a cross-sectional retrospective review of subjects undergoing any of 10 FPRS procedures between July 2016 and November 2019 at a tertiary care hospital with analysis of demographic factors, opioid prescription rates, and MMEs over time. Results: Of 863 patients included, 107 and 575 patients were prescribed postoperative opioids before and after opiate legislation enactment, respectively, with no difference in baseline demographics between groups. Regression analysis showed no change in MME prescribing in the year before legislation (p = 0.70), followed by a decrease of 0.13 MME per day (p = 0.00), with a subsequent stabilization of MME at a reduced rate for the remainder of the study period (p = 0.74). Conclusion: Enactment of the Michigan Opioid Laws was temporally associated with a decrease in opioid prescriptions for common facial plastic surgery procedures.

RESUMEN

Importance: Understanding whether statewide legislation, such as the Michigan Opioid Laws, is associated with reduction in postoperative opioid prescriptions is informative in guiding future legislation. Objective: To identify changes in opioid prescribing patterns for oculoplastic and orbital procedures associated with the enactment of the Michigan Opioid Laws in 2017 and 2018. Design, Setting, and Participants: This cross-sectional study included 3781 patients who underwent any of 10 common oculoplastic and orbital procedures between June 1, 2016, and November 30, 2019, at a tertiary care institution. Exposures: From 2017 to 2018, Michigan enacted a series of laws to address the state's worsening opioid epidemic. Two major components of this legislation enacted on June 1, 2018, required prescribers to review a report of patients' opioid use history and obtain signed consent after educating patients on the use and disposal of opioids prior to prescribing. Main Outcomes and Measures: Demographic information, type of surgery, type and amount of opioid prescriptions, and morphine milligram equivalent (MME) were analyzed. MME was calculated as the product of dose, quantity, and opioid-specific conversion factor for each prescription. Linear interpolation spline regression was used to evaluate the association of prescription MME with time. Results: Of 3781 patients, 1614 (42.7%) were male. The mean (SD) age at the time of surgery was 63.3 (16.6) years. Of 2026 patients undergoing surgery before June 1, 2018, 1782 (88.0%) were prescribed postoperative opioids; of 1755 patients undergoing surgery after June 1, 2018, 878 (50.0%) were prescribed postoperative opioids (P < .001). There was no difference in age, sex, race/ethnicity, surgery type, or opioids prescribed between these 2 cohorts. Linear interpolation spline regression showed a decrease of 26.025 MMEs (equivalent to a 36.2% reduction of mean MME) between June 1, 2017, and September 30, 2018 (ß, -1.735; 95% CI, -0.088 to -0.024; P < .001), stabilizing at a persistently reduced rate of MME prescribed through the end of the study period (October 1, 2018, to November 30, 2019; ß, -0.005; 95% CI, -0.039 to 0.016; P = .42). Changes in MME in the 12 months before or 12 months after the period of legislation enactment were not identified. Conclusions and Relevance: In this cross-sectional study, reduction in opioid prescriptions for oculoplastic and orbital procedures was observed during the enactment period of the Michigan Opioid Laws and appeared to be sustained through the end of the study period. Similar statewide or national legislations aimed at increasing prescriber awareness and patient education on opioid use may help curtail the prescription opioid epidemic.

RESUMEN

Facial reconstruction may be effectively performed in an office setting using a variety of techniques. Careful patient selection is paramount for achieving successful outcomes in this setting. The most common reconstructive techniques used in the office setting include local flaps and skin grafts. Scar management is complementary to all facial reconstructive procedures, and the reconstructive surgeon has a large variety of scar management techniques available. Scar management should be individualized based on clinical setting and available resources.

RESUMEN

Nasal reconstructive techniques have advanced significantly over the past 50 years. Modern techniques in nasal reconstruction are based on the nasal aesthetic subunits. In order to achieve ideal outcomes, reconstructive surgeons must consider differences in tissue qualities across the nasal aesthetic subunits and formulate reconstructive plans based on these differences. Local flaps, skin grafts, and several types of interpolated flaps comprise the most commonly used techniques for nasal reconstruction. Defects that involve structural or internal lining defects require reconstruction of significantly higher complexity.

RESUMEN

OBJECTIVE: Measure the attentional distraction of facial deformity related to severe thyroid-associated orbitopathy using three-dimensional (3D) images and eye-tracking technology. METHODS: Observers recruited at an academic tertiary referral center viewed 3D facial images of patients with severe thyroid-associated orbitopathy (TAO) and controls without TAO. An infrared eye-tracking monitor recorded their eye movements and fixations in real time. Multivariate Hotelling's analysis, followed by planned posthypothesis testing, was used to compare fixation durations for predefined regions of interest, including the eyes, nose, mouth, central triangle, and remaining face without the central triangle between severe TAO patients and controls. RESULTS: One hundred sixteen observers (mean age 26.4 years, 51% female) successfully completed the eye-tracking experiment. The majority of their attention was directed toward the central triangle (eyes, nose, mouth). On multivariate analysis, there were significant differences in the distribution of attention between control and severe TAO faces (T2 = 49.37; F(5,922) = 9.8314, P < 0.0001). On planned posthypothesis testing, observers attended significantly more to the eyes (0.77 seconds, P < 0.0001, 95% confidence interval [CI], 0.51, 1.03 seconds) and less to the nose (-0.42 seconds, P < 0.0001, 95% CI, -0.23, -0.62 seconds) in severe TAO patients. There was no significant difference in time spent on the mouth, the total time spent on the central triangle, or time spent in the remaining face between the two groups. CONCLUSION: Severe TAO distracted observer attention toward the eyes compared to control patients. These data lend insight into how TAO may alter observers' perceptions of these patients. Future studies should investigate how these changes in observer gaze patterns may reflect the social perception of TAO patients. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1250-1254, 2019.

RESUMEN

IMPORTANCE: Ehlers-Danlos syndromes (EDSs) are a group of heritable connective tissue disorders. Patients with EDSs can develop excessive facial rhytids, nasal deformities, and facial scarring, for which they may seek consultation with a facial plastic surgeon. Ehlers-Danlos syndromes can be associated with serious surgical complications and should be identified preoperatively to facilitate optimal treatment. To our knowledge, no management guidelines for patients with EDSs exist in the facial plastic surgery literature. We present a review of the literature and management recommendations for the facial plastic surgeon. OBSERVATIONS: We performed a PubMed/MEDLINE search for all publications in the English language related to surgical experience in patients with EDSs. A total of 37 publications (including reviews and case series) were included. Ehlers-Danlos syndromes are more common than appreciated, with an overall point prevalence between 1 in 2500 and 1 in 5000 according to existing literature. There are 6 main subtypes of EDSs that have significant phenotypic heterogeneity. Patients with classic type and hypermobile EDS (the 2 most common subtypes) can typically undergo elective facial plastic surgery without major complications. However, specific preoperative, intraoperative, and postoperative issues, as outlined in this review, must be taken into consideration. Vascular EDS should serve as a contraindication to elective surgery given its potential for life-threatening complications. CONCLUSIONS AND RELEVANCE: Because of their skin laxity, patients with EDSs may present more frequently to facial plastic surgeons' offices. Simple screening questions can help the surgeon identify potential patients with EDSs. Treatment should be individualized and performed with extreme care to ensure optimal outcomes.

RESUMEN

PURPOSE: Facial palsy (FP) can result in serious ophthalmic sequelae including loss of vision. We describe the clinical characteristics of FP patients presenting for ophthalmologic evaluation and the timing for initiating ophthalmologic care. METHODS: We performed a retrospective review of 96 consecutive FP patients presenting between 1992 and 2015 at a tertiary eye center. The main outcome measures were time interval from the diagnosis of FP and onset of ocular symptoms to the initial ophthalmologic evaluation (IOE), and the severity of exposure keratopathy and eyelid malposition on IOE. RESULTS: The median time interval from the diagnosis of FP to the IOE was 1.6 years (interquartile range; IQR = 0.5-9.2), and from the onset of ocular symptoms to IOE was 0.8 years (IQR = 0.3-2.3). The most common ocular symptoms were dryness (47.9%; n = 46), irritation (39.6%; n = 38), and tearing (30.2%; n = 29). A total of 26.0% (n = 25) of patients were bothered by the appearance of their eyes. Only 13.5% (n = 13) noted change in vision. On IOE, 81.6% (n = 75) of patients had punctate epithelial erosions (PEE), of which 52.3% (n = 35) had moderate to severe PEE, 3.3% (n = 3) had corneal ulcers and 2.2% (n = 2) had corneal abrasions. The average margin-reflex distance 2 was 6.4 mm (SD = 2.4) with average lagophthalmos of 3.5 mm (SD = 3.1). CONCLUSIONS: Among FP patients presenting for ophthalmologic evaluation, exposure keratopathy (as evidenced by PEE and corneal ulcers/abrasions) is highly prevalent and moderately severe on IOE, despite only 13.5% of patients noting decreased vision. These findings underscore the importance of timely and thorough ophthalmologic evaluation of FP patients.

RESUMEN

IMPORTANCE: Body dysmorphic disorder (BDD) is a relative contraindication for facial plastic surgery, but formal screening is not common in practice. The prevalence of BDD in patients seeking facial plastic surgery is not well documented. OBJECTIVE: To establish the prevalence of BDD across facial plastic and oculoplastic surgery practice settings, and estimate the ability of surgeons to screen for BDD. DESIGN, SETTING, AND PARTICIPANTS: This multicenter prospective study recruited a cohort of 597 patients who presented to academic and private facial plastic and oculoplastic surgery practices from March 2015 to February 2016. METHODS: All patients were screened for BDD using the Body Dysmorphic Disorder Questionnaire (BDDQ). After each clinical encounter, surgeons independently evaluated the likelihood that a participating patient had BDD. Validated instruments were used to assess satisfaction with facial appearance including the FACE-Q, Blepharoplasty Outcomes Evaluation (BOE), Facelift Outcomes Evaluation (FOE), Rhinoplasty Outcomes Evaluation (ROE), and Skin Rejuvenation Outcomes Evaluation (SROE). RESULTS: Across participating practices (9 surgeons, 3 sites), a total of 597 patients were screened for BDD: 342 patients from site 1 (mean [SD] age, 44.2 [16.5] years); 158 patients, site 2 (mean [SD] age, 46.0 [16.2] years), site 3, 97 patients (mean [SD] age, 56.3 [15.5] years). Overall, 58 patients [9.7%] screened positive for BDD by the BDDQ instrument, while only 16 of 402 patients [4.0%] were clinically suspected of BDD by surgeons. A higher percentage of patients presenting for cosmetic surgery (37 of 283 patients [13.1%]) compared with those presenting for reconstructive surgery (21 of 314 patients [6.7%]) screened positive on the BDDQ (odds ratio, 2.10; 95% CI, 1.20-3.68; P = .01). Surgeons were only able to correctly identify 2 of 43 patients (4.7%) who screened positive for BDD on the BDDQ, and the positive likelihood ratio was only 1.19 (95% CI, 0.28-5.07). Patients screening positive for BDD by the BDDQ had lower satisfaction with their appearance as measured by the FACE-Q, ROE, BOE, SROE, and FOE. CONCLUSIONS AND RELEVANCE: Body dysmorphic disorder is a relatively common condition across facial plastic and oculoplastic surgery practice settings. Patients who screen positive on the BDDQ have lower satisfaction with their facial appearance at baseline. Surgeons have a poor ability to screen for patients with BDD when compared with validated screening instruments such as the BDDQ. Routine implementation of validated BDD screening instruments may improve patient care. LEVEL OF EVIDENCE: NA.

RESUMEN

Facial paralysis can result in serious ocular consequences. All patients with orbicularis oculi weakness in the setting of facial nerve injury should undergo a thorough ophthalmologic evaluation. The main goal of management in these patients is to protect the ocular surface and preserve visual function. Patients with expected recovery of facial nerve function may only require temporary and conservative measures to protect the ocular surface. Patients with prolonged or unlikely recovery of facial nerve function benefit from surgical rehabilitation of the periorbital complex. Current reconstructive procedures are most commonly intended to improve coverage of the eye but cannot restore blink.

RESUMEN

IMPORTANCE: The impact of facial defects on quality of life as perceived by society and the value society places on facial reconstruction are important outcomes measures. OBJECTIVE: To measure the health state utility and dollar value of surgically reconstructing facial defects as perceived by society. DESIGN, SETTING, AND PARTICIPANTS: A randomized observational study conducted in an academic tertiary referral center using a socioeconomically diverse group of 200 casual observers. MAIN OUTCOMES AND MEASURES: Observers viewed images of faces with defects of varying sizes and locations before and after surgical reconstruction. Observers imagined if the defect in each image were on their own face and rated (1) their health state utility with the defect and (2) how much they would be willing to pay to have the defect surgically repaired to normal (perfect repair). Established health state utility and contingent valuation metrics were used. RESULTS: Data from 200 observers were analyzed. Facial defects significantly decreased perceived health state utility with the greatest penalty attributed to large and centrally located defects. Surgical reconstruction of the facial defects increased health state utility to near-normal ranges for all groups except large central defects. Participants were willing to pay an average of $1170 (95% CI, $767-$1572) to repair a de novo small peripheral defect; they were willing to pay $4274 more than the average (95% CI, $3296-$5251) to repair a large defect and $2372 more (95% CI, $1379-$3366) to repair a central defect. Using these valuation and health utility data, we calculated willingness to pay per quality-adjusted life-year (WTP/QALY), a value-related metric. Mean WTP/QALY ratios ranged from $639/QALY for repairing small peripheral defects to $2838/QALY for repairing large central defects, well below all cost-effectiveness thresholds. CONCLUSIONS AND RELEVANCE: Casual observers perceived that facial defects significantly decrease quality of life, an effect improved by reconstructive surgery. Measuring WTP and calculating WTP/QALY provides novel data to assess the social importance and value of facial reconstructive surgery. To our knowledge, these are the first data demonstrating that surgical reconstruction of facial defects is a high-value intervention as perceived by society. These findings have implications for a broad range of stakeholders, including patients, surgeons, health policy makers, and payers. LEVEL OF EVIDENCE: NA.

RESUMEN

BACKGROUND: Factors associated with disease-free survival (DFS) after salvage therapy for recurrent oropharyngeal squamous cell carcinoma (SCC) in the context of human papillomavirus (HPV) are poorly understood. METHODS: A retrospective cohort analysis was conducted of patients with recurrent oropharyngeal SCC with known HPV tumor status who received salvage therapy. RESULTS: Eighty-six patients were eligible for analysis. Sixty-four patients (74%) were HPV-positive. In multivariable analysis, HPV-positive tumor status (hazard ratio [HR] = 0.30; 95% confidence interval [CI] = 0.13-0.71; p = .007), clinical response to any salvage therapy (HR = 0.29; 95% CI = 0.11-0.77; p = .01), and surgical salvage (HR = 0.38; 95% CI = 0.16-0.88; p = .02) were associated with improved overall survival (OS). Positive surgical margin was associated with worse DFS after salvage (HR = 8.43; 95% CI = 1.99-35.70; p = .004). CONCLUSION: For recurrent oropharyngeal SCC, HPV-positive tumor status, surgical salvage, and clinical response to salvage therapy are independently associated with improved OS, but not DFS after salvage. Surgical margin is the only independent predictor of DFS. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1501-E1509, 2016.

RESUMEN

Here we describe the development of a novel specific, rapid ELISA system, which is performed on modified microplates where polyvinylidine fluoride (PVDF) forms the base of each well. The use of microplates with PVDF membranes as the solid phase allows for a greater binding capacity of protein in comparison to the solid phases of traditional ELISAs. The increased binding capacity of the solid phase provides for the direct binding of antigens, which can subsequently be assayed using a single, specific and well-characterized antibody. This direct assay system eliminates the need for two distinct antibodies that are often necessary in conventional two site ELISA systems. The system is able to specifically detect purified proteins as well as antigens in crude preparations of tissue homogenates. The PVDF-based ELISA performs with similar sensitivity and reproducibility as conventional two site ELISAs in tissue homogenates. The intra- and inter-assay coefficients of variation for the measurement of actin in crude rat brain homogenate were 2.36 and 5.15%, respectively.

RESUMEN

OBJECTIVES: For patients with tobacco-related head and neck squamous cell carcinoma (HNSCC), the occurrence of a second primary tumor (SPT) is an ominous development that is attributed to a field cancerization effect and portends a poor clinical outcome. The goal of this study was to determine whether patients with human papillomavirus (HPV)-related index tonsillar carcinomas can also develop SPTs in the contralateral tonsil, and to discern the molecular etiology of HPV-related tumor multifocality. MATERIALS AND METHODS: The surgical pathology archives of The Johns Hopkins Hospital were searched for all patients with primary HPV-related tonsillar squamous cell carcinoma who developed a synchronous or metachronous carcinoma in the contralateral tonsil. The HPV-16 E6 exon was sequenced from each independent cancer site to determine whether the tumor pairs harbored the same or a different HPV-16 variant. RESULTS: Four patients with bilateral HPV-related tonsillar carcinomas were identified. In every case, the HPV DNA sequences derived from the index tumor and corresponding SPT were 100% concordant, indicating that the index and SPTs were caused by the same HPV-16 variant. CONCLUSION: For the small subset of patients with tonsillar carcinomas who develop SPTs in the contralateral tonsil, the index case and the SPT consistently harbored the same HPV variant. This finding suggests that HPV-related tumor multi-focality can be attributed either to independent inoculation events by the same virus, or by migration of HPV-infected cells from a single inoculation site to other regions of Waldeyer's ring.

RESUMEN

Human papillomavirus (HPV) is now recognized to cause a subset of head and neck squamous cell carcinomas (HNSCC). Although excessive tobacco and alcohol use continue to be important risk factors for HNSCC, epidemiologic studies suggest that more than 25% of HNSCC are now caused by HPV. The incidence of HPV-related HNSCC is increasing, highlighting the need to understand the oral HPV infections causing these cancers. This article reviews the evidence for a causal association between HPV and HNSCC, examines the changing epidemiologic trends of HNSCC, and discusses what is currently known about oral HPV infection, natural history, and transmission.

RESUMEN

OBJECTIVES: Identify factors related to patient/family satisfaction in an academic pediatric otolaryngology clinic and suggest strategies to improve patient and family satisfaction. METHODS: Patients and families were surveyed following clinic encounters between May, 2010 and April, 2011. Review of an ongoing continuous quality improvement (CQI) effort. Univariable and multivariable ordinal logistic regression analyses were used to evaluate the relationship between reception area and examination room wait times, assessment of the provider, and clinic volume with overall satisfaction. RESULTS: 1415 clinical encounters in the pediatric otolaryngology clinic resulted in 962 responses for a response rate of 68%. Ordinal logistic regression showed a significant relationship between overall satisfaction and satisfaction with the provider (cumulative odds ratio [COR]=51.0; 95% CI: 29.5, 88.2; P<0.001), examination room wait time (COR=23.0; 95% CI: 15.0, 35.1; P<0.001), reception area wait time (COR=13.6; 95% CI: 9.41, 19.8; P<0.001), and increases in clinic volume below 22 patients per day (COR=0.86; 95% CI: 0.75, 0.99; P=0.033). Multivariable analysis showed that satisfaction with provider (COR=32.2; 95% CI: 14.5, 71.8; P<0.001), reception area wait time (COR=3.8; 95% CI: 1.8, 7.6; P<0.001), and examination room wait time (COR=2.8; 95% CI: 1.3, 6.1; P=0.005) were independently associated with overall satisfaction. CONCLUSIONS: Examination room wait times and reception area wait times are associated with overall satisfaction and should be minimized.

RESUMEN

CONTEXT: Albright hereditary osteodystrophy (AHO) is a rare genetic disorder characterized by phenotypic abnormalities including brachydactyly/brachymetacarpia, short stature, and sc ossifications. Carpal tunnel syndrome (CTS) is a chief complaint in many patients with AHO. OBJECTIVE: The objective of the study was to investigate the prevalence of CTS in patients with AHO. DESIGN: This was a cross-sectional study. SETTING: The study was conducted at the Clinical Research Center (Institute of Clinical and Translational Medicine), Johns Hopkins University School of Medicine and Albright Clinic, Kennedy Krieger Institute. PARTICIPANTS: Thirty-three subjects with a diagnosis of AHO participated in the study. MAIN OUTCOME MEASURES: We assessed for the presence and location of hand tingling, numbness, pain, weakness, flick sign, difficulty with fine motor skills, severe hand or nail biting, and nocturnal symptoms in the setting of normocalcemia and a euthyroid state. Patients were considered to have CTS if they were positive for three of these symptoms. All subjects were analyzed for mutations in the GNAS gene. RESULTS: Twenty-two subjects (67%) had a clinical diagnosis of CTS (95% confidence interval 0.48, 0.82). Twenty-eight of 33 subjects were confirmed to have mutations in GNAS, of whom 68% had CTS (95% confidence interval 0.48, 0.84). There were 14 children in this study; 36% had a clinical diagnosis of CTS. Body mass index, brachydactyly/brachymetacarpia, prior GH treatment, and specific GNAS mutations were not associated with CTS. CONCLUSIONS: We report a high prevalence of CTS in both adults and children with AHO. The diagnosis of CTS should be considered when evaluating a patient with AHO because the intervention for CTS could improve overall function and quality of life in these patients.
