RESUMEN

BACKGROUND: Whether pembrolizumab given both before surgery (neoadjuvant therapy) and after surgery (adjuvant therapy), as compared with pembrolizumab given as adjuvant therapy alone, would increase event-free survival among patients with resectable stage III or IV melanoma is unknown. METHODS: In a phase 2 trial, we randomly assigned patients with clinically detectable, measurable stage IIIB to IVC melanoma that was amenable to surgical resection to three doses of neoadjuvant pembrolizumab, surgery, and 15 doses of adjuvant pembrolizumab (neoadjuvant-adjuvant group) or to surgery followed by pembrolizumab (200 mg intravenously every 3 weeks for a total of 18 doses) for approximately 1 year or until disease recurred or unacceptable toxic effects developed (adjuvant-only group). The primary end point was event-free survival in the intention-to-treat population. Events were defined as disease progression or toxic effects that precluded surgery; the inability to resect all gross disease; disease progression, surgical complications, or toxic effects of treatment that precluded the initiation of adjuvant therapy within 84 days after surgery; recurrence of melanoma after surgery; or death from any cause. Safety was also evaluated. RESULTS: At a median follow-up of 14.7 months, the neoadjuvant-adjuvant group (154 patients) had significantly longer event-free survival than the adjuvant-only group (159 patients) (P = 0.004 by the log-rank test). In a landmark analysis, event-free survival at 2 years was 72% (95% confidence interval [CI], 64 to 80) in the neoadjuvant-adjuvant group and 49% (95% CI, 41 to 59) in the adjuvant-only group. The percentage of patients with treatment-related adverse events of grades 3 or higher during therapy was 12% in the neoadjuvant-adjuvant group and 14% in the adjuvant-only group. CONCLUSIONS: Among patients with resectable stage III or IV melanoma, event-free survival was significantly longer among those who received pembrolizumab both before and after surgery than among those who received adjuvant pembrolizumab alone. No new toxic effects were identified. (Funded by the National Cancer Institute and Merck Sharp and Dohme; S1801 ClinicalTrials.gov number, NCT03698019.).

RESUMEN

BACKGROUND: There are no guidelines on when to more strongly recommend sentinel lymph node biopsy (SLNB) for T1b melanomas. OBJECTIVE: To examine whether anatomic locations of T1b melanomas and patient age influence metastases. METHODS: We conducted a retrospective study using data from two hospitals in Los Angeles County from January 2010 through January 2020. RESULTS: Out of 620 patients with primary melanomas, 566 melanomas were staged based on the American Joint Committee on Cancer 8th edition melanoma staging. Forty-one were T1b, of which 13 were located on the face/ear/scalp and 28 were located elsewhere. T1b melanomas located on the face/ear/scalp had an increased risk of lymph node or distant metastasis compared with other anatomic sites (31% vs 3.6%, P=0.028). For all melanomas, the risk of lymph node or distant metastasis decreased with age of 64 years or greater (P<0.001 and P=0.034). For T1b melanomas, the risk of distant metastasis increased with increasing age (P=0.047). LIMITATIONS: Data were from a single county.  Conclusion: T1b melanomas of the face/ear/scalp demonstrated a higher risk of lymph node or distant metastasis and may help guide the recommendation of SLNB, imaging, and surveillance. Younger patients may be more strongly considered for SLNB and older patients with T1b melanomas may warrant imaging.  J Drugs Dermatol. 2024;23(5):306-310. doi:10.36849/JDD.7667.

RESUMEN

IMPORTANCE: While minorities represent around 20 % of all HNC patients, these demographics are largely understudied. Furthermore, trends in national studies may not always be fully replicated in locoregional populations, indicating a need for more nuanced study. OBJECTIVE: To better understand our patient population, we sought to understand differences in presentation, management, and outcome between Caucasians and minority groups with HNC. DESIGN: Retrospective cohort analysis of the Los Angeles County Surveillance Epidemiology and End Results (SEER) database. SETTING: Los Angeles County. PARTICIPANTS: All patients in Los Angeles County diagnosed with cancer of the head and neck from January 1, 1988 to December 31, 2018. MAIN OUTCOMES AND MEASURES: The primary outcome in our study was significant differences between racial and ethnic groups in age of diagnosis, sex, socioeconomic quintile, insurance status, stage at diagnosis, treatment modality, time to first treatment, and cancer-specific cause of death. RESULTS: Our 18,510-patient cohort was largely male (64.35 %), white (69.57 %), and were on average 62.84 years old (SD = 20.07). When stratifying patients by race and ethnicity, significant differences were found in average age at diagnosis, sex, socioeconomic quintile, insurance status, and stage at diagnosis, treatment modalities utilized, and time to first treatment (all p < 0.001). Relative to all other head and neck patients, minority groups were significantly younger, had lower proportions of male patients, were less likely to pursue surgery, were more likely to pursue chemotherapy or radiation, and endorsed longer time to first treatment (all p < 0.001). The distribution of socioeconomic quintile (all p < 0.001), insurance status (all p < 0.001), and stage at diagnosis (all p < 0.05) also significantly varied between minority and reference groups. Only African Americans exhibited significantly higher rates of cancer-specific cause of death relative to non-African Americans (p < 0.001). CONCLUSIONS AND RELEVANCE: Pervasive socioeconomic disparities between Caucasian HNC patients and those of other minority racial and ethnic groups in Los Angeles County that likely and significantly impact the diagnosis and management of HNC and its resultant outcomes. We encourage others to similarly examine their local populations to tailor the quality of care provided to patients.

RESUMEN

PURPOSE: Not much is known about how pre-operative psychosocial factors affect head and neck free flap outcomes. Hence, the objective of the study is to determine if a patient's pre-operative self-perception and quality of life affect post-operative complications and hospital length of stay after free flap surgery. MATERIALS AND METHODS: This was a prospective cohort study. Patients who underwent a free flap surgery at an academic tertiary care center between January 2021 and March 2022 were asked to fill out the Rosenberg Self Esteem Scale and the Short Form 36 Health Questionnaire before surgery. A chart review of their medical records was then performed. Analysis of the data was performed using Spearman Correlation, Fisher exact test, Mann-Whitney and Multivariate Logistic Regression on STATA 15. RESULTS: Sixty-one patients (73.8 % male; mean [SD; range] age: 60.9 [14.0, 23.1-86.8]) who underwent free flap surgery agreed to participate in the study. Most of the participants were not Caucasian (59 %). The most common indication for surgery was malignancy (93 %). The post-operative complication rate was 34.4 % and included 3 hematoma (4.9 %), 3 free flap failure (4.9 %), 9 wound dehiscence (14.8 %), 10 salivary fistulas (16.4 %), and 3 aspiration pneumonia or chyle leak (4.9 %). There were no mortalities. The mean role limitations due to physical health subscore [SD; range], social functioning subscore, pain subscore, and general health subscore of the SF-36 were 61.9 [39.2, 0-100], 70.7 [27.5, 0-100], 62.1 [25.7, 0-100], and 67.8 [20.3, 20-100], respectively. On univariate analysis, decreased physical limitations, better social functioning, less pain and better general health were associated with fewer overall post-operative complications, but was not correlated with length of stay. This held true for social functioning and general health even in multivariate analysis accounting for age and smoking history. The mean Rosenberg Self Esteem Scale score was 24.3 [4.1, 13-30]. CONCLUSIONS: In this study, patients with more limited social function and worse general health had more overall post-operative complications. It is important to continue to explore how pre-operative quality of life and other psychosocial factors can affect surgical outcomes.

RESUMEN

BACKGROUND: Jehovah's Witnesses are members of a Christian religious denomination that rejects the transfusion of whole blood and component blood products. Given new transfusion-free strategies, Jehovah's Witness patients are undergoing free flap reconstructions with increased regularity. However, outcome data remains limited. With this study, we sought to examine post-operative outcomes in Jehovah's Witness patients undergoing free flap reconstruction of the head and neck, compare their outcomes to non-Jehovah's Witness patients, and enumerate strategies to enhance the safety of transfusion-free surgery. METHODS: A retrospective chart review was carried out on 10 patients who identified as Jehovah's Witness and 63 patients who did not. Demographic information, pre-operative laboratory values, peri-operative resuscitative interventions, and peri-operative outcome measures were compiled. Descriptive data analysis, Mann-Whitney, Chi-square tests, and multivariate analysis were used. RESULTS: Jehovah's Witness patients were significantly older than non-Jehovah's Witness patients (p = 0.03) and had significantly higher ASA scores (p = 0.009). Head and neck cancer was the primary surgical indication in both groups (p = 0.71). Jehovah's witness patients have significantly less intraoperative blood loss (p = 0.011) and lower post-operative hemoglobin (p = 0.002) compared to non-Jehovah's Witness patients. While Jehovah's Witness patients had significantly higher rates of severe anemia (p = 0.014), there was no significant difference between the two groups in other post-operative complications and readmission rates even in a multivariate analysis accounting for age and ASA score. CONCLUSIONS: Free flap microvascular reconstruction can be reliably performed on Jehovah's Witness head and neck patients without an increased risk of complication. Policies such as the use of non-blood volume expanders, albumin, Epogen, perioperative iron supplementation, cell saver and acute normovolemic hemodilution are key to ensuring good outcomes.

RESUMEN

PURPOSE: Adequate distal skin paddle perfusion is essential to preventing postoperative flap necrosis in head and neck reconstruction. To describe the use of indocyanine green angiography (ICGA), to assess skin paddle perfusion in the setting of head and neck reconstruction with the supraclavicular artery island flap at a single institution and assess the effect of ICGA use on the rate of postoperative skin paddle necrosis. METHODS: A retrospective cohort study consistently of patients who underwent head and neck reconstruction with a supraclavicular artery island flap for any indication at a tertiary medical center from 2010 to 2018. The predictor variable was ICGA use. The primary outcome was rate of skin paddle necrosis. Secondary outcomes included rates of post-operative overall complications, dehiscence, fistula, and reoperation. Covariates included demographic, operative, flap perfusion assessment, and postoperative variables. Retrospective assessment of distal flap perfusion was performed on available ICGA video recordings. Descriptive and bivariate statistics were computed. Statistical significance was set at P ≤ .05. RESULTS: A total of 104 patients were included and ICGA was used in 23 cases. In 10 of these cases, flap trimming was performed due to concern of flap hypoperfusion on ICGA. The median relative distal flap perfusion was 16.7 ± 2.6% in trimmed flaps, compared to 35 ± 13.2% in untrimmed flaps. ICGA use was not associated with rate of skin paddle necrosis (P = .76). CONCLUSIONS: ICGA is a viable method of assessing intraoperative supraclavicular artery island skin paddle perfusion and can help determine the need for distal flap trimming when tissue viability based on clinical findings alone is uncertain. ICGA use for skin paddles with uncertain perfusion on intraoperative clinical findings prevented a potential increase in postoperative necrosis compared to that of skin paddles with adequate perfusion on intraoperative clinical findings. Future studies are required to determine the minimum distal perfusion value that indicates hypoperfusion and the need for flap modification.

RESUMEN

PURPOSE: This study aims to elucidate any relationship between prior tonsillectomy and the presence of oropharyngeal HPV DNA found in screening mouth rinses. MATERIALS AND METHODS: A cross sectional study was conducted using the 2011-2014 National Health and Nutrition Examination Survey (NHANES). Participants between 40 and 69 were included in the study and medical, surgical, and sexual health history were recorded. Multivariable analyses were conducted to examine factors associated with HPV prevalence in oral rinse samples. RESULTS: A total of 4825 participants were recorded with 21.1 % having a history of tonsillectomy. In the no tonsillectomy group, 8.6 % of respondents had a positive oral rinse for HPV, while 7.2 % of those with a tonsillectomy had a positive rinse sample. There was no association between age and HPV prevalence (OR = 1.04, 95 % CI: [1.00-1.07]). When controlling for demographics, medical history, and sexual behaviors, tonsillectomy history was not shown to have an association with HPV (OR = 0.86, 95 % CI: [0.53-1.40]). However, men, Hispanics, smokers, and those with higher lifetime sexual partners had increased odds of having a positive HPV oral rinse sample which was statistically significant. CONCLUSION: Our data showed that a history of tonsillectomy was not significantly associated with the presence of HPV in an oral rinse. However, a significant relationship was seen between the presence of HPV in oral rinses and certain demographic factors such as male gender, Hispanic race, smoking history, and increased sexual partners.

RESUMEN

PURPOSE: Plate extrusion after mandibular reconstruction is a complication that imposes significant morbidity on the patient. The goal of this study is to estimate the incidence of plate extrusion after mandible reconstruction with a vascularized free flap and to identify the factors associated with plate extrusion. METHODS: This was a retrospective cohort study involving patients who underwent mandibular reconstruction from October 2008 to July 2019 at LAC + USC or Keck Hospital of USC. Inclusion criteria were age ≥ 18 years, single-stage mandibular reconstruction with vascularized free flap, and follow-up of at least 12 months. Relevant demographic, intraoperative, and postoperative data were collected. The primary outcome was postoperative plate extrusion within the 12-month follow-up. Descriptive, univariate, and multivariate analyses were performed. Statistical significance was set at P ≤ .05. RESULTS: A total of 102 patients were included in this study. The majority received a fibula free flap (90%) for a malignant neoplasm (76%). All patients had at least 12 months of follow-up. The rate of plate extrusion was 16%, with the majority of those patients undergoing plate removal (69%). After adjusting for postoperative fistula, soft tissue, and length of hospitalization, we found that any history of smoking (odds ratio = 12.8; confidence interval, 1.57 to 104.2), number of osteotomies (odds ratio 3.07; confidence interval, 1.09 to 8.6), flap nonviability (odds ratio = 18.2; confidence interval, 2.22 to 148.8) were associated with plate extrusion on multivariate analysis. Postoperative soft tissue infection approached significance. CONCLUSIONS: This study demonstrates that smoking history, number of osteotomies, and flap nonviability are associated with plate extrusion after mandible reconstruction. Performing fewer osteotomies when possible to avoid excessively small flap bone segments and minimizing postoperative complications may improve long-term outcomes after mandibular reconstruction.

RESUMEN

The purpose of this study is to analyze outcomes of combined antegrade-retrograde dilations (CARD). This retrospective study was conducted on 14 patients with a history of head and neck cancer, treated with radiation therapy that was complicated by either complete or near-complete esophageal stenosis. All patients had minimal oral intake and depended on a gastrostomy tube for nutrition. Swallow function before and after CARD was assessed using the Functional Oral Intake Scale, originally developed for stroke patients and applied to head and neck cancer patients. Patients undergoing CARD demonstrated a quantifiable improvement in swallow function (p = 0.007) that persisted at last known follow-up (p = 0.015) but only a minority (23.1%) achieved oral intake sufficient to obviate the need for tube feeds. Complication rates were 24% per procedure or 36% per patient, almost all complications required procedural intervention, and all complications occurred in patients with complete stenosis. Our study suggests further caution when considering CARD, careful patient selection, and close post-operative monitoring.

RESUMEN

OBJECTIVES: To investigate the differences in oral HPV infection and sexual behaviors by race in the US. MATERIALS AND METHODS: We analyzed data from the 2011-2014 US National Health and Nutrition Examination Survey during which participants aged 18-69 years completed oral rinse exam for HPV detection (n = 8,229). Logistic regression was used to examine the associations of race with various types of oral HPV infection and sexual behaviors. RESULTS: The prevalence of overall oral HPV infection and HPV type16 infection was 7.5% [95% CI: 6.6-8.4] and 1.1% [95% CI: 0.7-1.3], respectively. Blacks were more likely to have any oral HPV infection [OR: 1.22, 95% CI: 1.01-1.47] and Asian Americans were less likely to have any oral HPV infection [OR: 0.33, 95% CI: 0.24-0.49] than Whites. In a multivariate model, Whites were less likely to have any oral HPV infections than Blacks while having higher order of impact by the number of lifetime sex partners. Overall, Asian Americans were less likely to have type16 infection [OR: 0.21, 95% CI: 0.06-0.67] than Whites; however, that difference disappears when adjusting for sexual behaviors. CONCLUSIONS: In this nationally representative sample of US adults, the prevalence of overall oral HPV infections was higher among Blacks and lower among Asians in comparison to Whites. Further analysis with sexual behavior data suggested that the racial differences in prevalence are likely due to different sexual behaviors.

RESUMEN

Complex skull base tumors can involve critical vessels of the head and neck. To achieve a gross total resection, vessel sacrifice may be necessary. In cases where vessel sacrifice will cause symptomatic cerebral ischemia, surgical revascularization is required. The purpose of this paper is to review cerebral revascularization for skull base tumors, the indications for these procedures, outcomes, advances, and future directions.

RESUMEN

BACKGROUND: There are multiple known risk factors for the development of cutaneous squamous cell carcinoma (SCC). OBJECTIVE: To determine whether patients with cutaneous SCC have a higher prevalence of hypothyroidism than the general US population. MATERIALS AND METHODS: A retrospective review was performed for patients seen at the University of Southern California with cutaneous SCC. Chart review was performed for the presence of hypothyroidism and thyroid replacement therapy before the diagnosis of SCC for each patient. Multiple prevalence studies were gathered from the literature for comparison, reporting the prevalence of overt and subclinical hypothyroidism in the general US population and/or elderly US population. RESULTS: Of the 265 patients diagnosed with SCC of the skin, 61 (23%) of patients were found to have a preceding diagnosis of hypothyroidism. The prevalence of hypothyroidism among the population of SCC patients was significantly greater than the prevalence of hypothyroidism (overt and subclinical) in any general and/or elderly US population reported. CONCLUSION: Patients with SCC of skin are more likely to have a history of hypothyroidism than the general population. The authors conclude that hypothyroidism may be linked to the development of cutaneous SCC.

RESUMEN

PURPOSE: Total lower lip and mandible defects following tumor resection present challenging reconstructions. The use of dual free flaps leads to increased donor-site morbidity and risk of flap failure. We present a single scapular free flap approach with unique use of osteotomies for lip reconstruction in a small series of patients. METHODS: A case series was conducted from 2007 to 2012 on three patients with squamous cell carcinoma of the oral cavity requiring large resection. Patients ranged in age from 34 to 64 years. A scapular free flap was used for reconstruction of mandible, floor of mouth, total lower lip and chin defects ranging in size from 7 × 4 cm to 11 × 7 cm. Harvested bone was extended medially beyond the lateral border of scapula. Osteotomies were oriented to support the soft tissue flap to rebuild lip height and restore oral competence. RESULTS: Skin paddles ranged in size from 10-11 cm × 18-25 cm. Bone flap size was not reported but vertical height of osteotomies ranged from 3-4 cm. All flaps survived microvascular transfer. One patient suffered from shoulder dysfunction and sialorrhea necessitating a second procedure. A second patient developed exposed hardware after radiation. Follow-up ranged from 10 to 36 months. All patients achieved good oral competence and cosmesis by 9 months post-operative. CONCLUSIONS: This single-flap approach may provide an alternative to dual free flap reconstruction of total lower lip and mandible. © 2016 Wiley Periodicals, Inc. Microsurgery 36:480-484, 2016.

RESUMEN

OBJECTIVE: To determine the cost-effectiveness of surveillance imaging with PET/CT scan among patients with human papillomavirus-positive oropharyngeal squamous cell carcinoma. STUDY DESIGN: Cost-effectiveness analysis. SETTING: Oncologic care centers in the United States with head and neck oncologic surgeons and physicians. METHODS: We compared the cost-effectiveness of 2 posttreatment surveillance strategies: clinical surveillance with the addition of PET/CT scan versus clinical surveillance alone in human papillomavirus-positive oropharyngeal squamous cell carcinoma patients. We constructed a Markov decision model which was analyzed from a third-party payer's perspective using 1-year Markov cycles and a 30-year time horizon. Values for transition probabilities, costs, health care utilities, and their studied ranges were derived from the literature. RESULTS: The incremental cost-effectiveness ratio for PET/CT with clinical surveillance versus clinical surveillance alone was $89,850 per quality-adjusted life year gained. Flexible fiberoptic scope exams during clinical surveillance would have to be over 51% sensitive or PET/CT scan cost would have to exceed $1678 for clinical surveillance alone to be more cost-effective. The willingness-to-pay threshold at which imaging surveillance was equally cost-effective to clinical surveillance was approximately $80,000/QALY. CONCLUSION: Despite lower recurrence rates of human papillomavirus-positive oropharyngeal cancer, a single PET/CT scan within 6 months after primary treatment remains a cost-effective tool for routine surveillance when its cost does not exceed $1678. The cost-effectiveness of this strategy is also dependent on the clinical surveillance sensitivity (flexible fiberoptic pharyngoscopy), and willingness-to-pay thresholds which vary by country.

RESUMEN

INTRODUCTION: Gay and bisexual males and other LGBTQ+ communities are more frequently exposed to factors associated with an increased risk of human papillomavirus (HPV) acquisition. Vaccination is critical to protect against HPV+ head and neck cancer (HNC). We characterized the association of perceived level of risk of contraction with HPV knowledge, and vaccine decision-making. STUDY DESIGN: Cross-sectional cohort. SETTING: LGBTQ and general survey Reddit forums (control). METHODS: A survey was shared amongst the online forums. Descriptive statistics characterized the data. Multivariable logistic regression was used to understand factors associated with vaccination, self-perceived high risk, and knowledge of HPV + HNC. RESULTS: Of 718 respondents, most were female (41.09%), Caucasian (59.89%), college-educated (33.01%), and insured (77.15%) with a mean age of 30.75 years. Half were vaccinated (49.16%), with most unvaccinated endorsing interest (60.58%). Few dependents were vaccinated (25.91%), with interest in vaccination among parents of unvaccinated children (38.58%). Knowledge of HIV's association with HPV (62.95%), HPV causing HNC (55.57%), and the vaccine's efficacy against HNC (55.57%) was also moderate. Identifying female (P = .042), a self-perceived high-risk (P < .001), and having vaccinated children (P < .001) increased vaccination likelihood; transgender (P = .021), or lesbian or gay sexual identity (P < .001) decreased likelihood. Personal HNC diagnosis (P < .001), self-vaccination (P < .001), having vaccinated children (P < .001), having anal sex (P = .001) or no knowledge of past HPV status (P < .001) increased likelihood of high self-perceived risk. CONCLUSION: Efforts to improve public education regarding the association between HPV and HNC and vaccination efficacy are required to better inform vaccine decision-making among individuals at risk for HPV infection.

RESUMEN

OBJECTIVE: With burgeoning popularity of artificial intelligence-based chatbots, oropharyngeal cancer patients now have access to a novel source of medical information. Because chatbot information is not reviewed by experts, we sought to evaluate an artificial intelligence-based chatbot's oropharyngeal cancer-related information for accuracy. METHODS: Fifteen oropharyngeal cancer-related questions were developed and input into ChatGPT version 3.5. Four physician-graders independently assessed accuracy, comprehensiveness, and similarity to a physician response using 5-point Likert scales. Responses graded lower than three were then critiqued by physician-graders. Critiques were analyzed using inductive thematic analysis. Readability of responses was assessed using Flesch Reading Ease (FRE) and Flesch-Kincaid Reading Grade Level (FKRGL) scales. RESULTS: Average accuracy, comprehensiveness, and similarity to a physician response scores were 3.88 (SD = 0.99), 3.80 (SD = 1.14), and 3.67 (SD = 1.08), respectively. Posttreatment-related questions were most accurate, comprehensive, and similar to a physician response, followed by treatment-related, then diagnosis-related questions. Posttreatment-related questions scored significantly higher than diagnosis-related questions in all three domains (p < 0.01). Two themes of the physician critiques were identified: suboptimal education value and potential to misinform patients. The mean FRE and FKRGL scores both indicated greater than an 11th grade readability level-higher than the 6th grade level recommended for patients. CONCLUSION: ChatGPT responses may not educate patients to an appropriate degree, could outright misinform them, and read at a more difficult grade level than is recommended for patient material. As oropharyngeal cancer patients represent a vulnerable population facing complex, life-altering diagnoses, and treatments, they should be cautious when consuming chatbot-generated medical information.

RESUMEN

Objective: This study aimed to characterize the quality of laryngectomy-related patient education on YouTube and understand factors impacting video content quality. Study Design: Cross-sectional cohort analysis. Setting: Laryngectomy-related videos on YouTube. Methods: YouTube was anonymously queried for various laryngectomy procedure search terms. Video quality was evaluated using the validated DISCERN instrument which assesses treatment-related information quality. Descriptive statistics were used to characterize our cohort. Univariate and multivariable linear regression were used to assess factors associated with increased DISCERN score. Significance was set at P < .05. Results: Our 78-video cohort exhibited moderate levels of engagement, averaging 13,028.40 views (SD = 24,246.93), 69.79 likes (SD = 163.75), and 5.27 comments (SD = 18.81). Videos were most frequently uploaded to accounts belonging to physicians (43.59%) or health care groups (41.03%) and showcased operations (52.56%) or physician-led education (20.51%). Otolaryngologists were featured in most videos (85.90%), and most videos originated outside the United States (67.95%). Laryngectomy videos demonstrated poor reliability (mean = 2.35, SD = 0.77), quality of treatment information (mean = 1.92, SD = 0.86), and overall video quality (mean = 1.97, SD = 1.12). In multivariable linear regression, operative videos were associated with lower video quality relative to nonoperative videos (ß = -1.63, 95% confidence interval [CI] = [-2.03 to -1.24], P < .001); the opposite was true for videos from accounts with higher subscriber counts (ß = 0.02, 95% CI = [0.01-0.03], P = .005). Conclusion: The quality and quantity of YouTube's laryngectomy educational content is limited. There is an acute need to increase the quantity and quality of online laryngectomy-related content to better support patients and caregivers as they cope with their diagnosis, prepare for, and recover from surgery.

RESUMEN

Ameloblastic carcinoma (AC) is a rare and aggressive malignant epithelial odontogenic tumor making up less than 1% of malignant head and neck tumors. The majority of cases occur in the mandible with a minority occurring in the maxilla. Most occur de novo, while rare cases of AC have resulted from transformation from ameloblastoma. Here, we present a case in which a 30-year-old man presented with proptosis and a recurrent right temporal mass, which had been previously diagnosed as ameloblastoma on surgical pathology. CT findings demonstrated local invasion, and he was subsequently taken to the operating room for right craniotomy, infratemporal and middle cranial fossa tumor resection, and right modified radical neck dissection with reconstruction. Final pathology, which included areas of early focal necrosis, loss of peripheral palisading, and hyperchromatism, confirmed the diagnosis of ameloblastoma with transformation to AC. We further discuss radiologic and histopathological signs of this rare tumor, as well as recommended treatment modalities.

RESUMEN

Although modified radical neck dissections have increased in popularity to reduce morbidity secondary to intraoperative accessory nerve damage, inadvertent injury still often occurs. As this phenomenon is thought to be due to anatomic variation in the trapezius branch of the accessory nerve, it is imperative to better understand the nuances of these anatomic variations to better inform surgical decision-making. A total of 24 accessory nerves were dissected, exposed, and traced in 15 cadavers. Three aspects of the accessory nerve were identified and recorded: the course of the trapezius branch in relation to the sternocleidomastoid, the number of trapezius branches at muscle insertion, and the number of cervical rootlet contributions. Four different anatomic patterns for the trapezius branch were identified, with the most common being where the trapezius branch separates from the main accessory nerve just medial to the sternocleidomastoid and courses deep to the sternocleidomastoid (58.3%). Most (75%) trapezius branches entered the muscle as a single nerve, whereas some (21%) were inserted as two separate nerves. The number of cervical rootlet contributions for each trapezius branch varied from zero to three. Bilateral anatomic variations were also noted. Even when the accessory nerve and its branches are thought to be spared during neck dissection, patients may postoperatively present with different degrees of accessory nerve damage. There may be unrecognized anatomic pathways that the nerve takes that may confer a higher risk of unintentional damage, especially those that have greater exposure within the anterior triangle unprotected by the sternocleidomastoid.

RESUMEN

Objective: To characterize the users of the head and neck cancer (HNC) online support group (OSG) and describe the perceived benefits of membership. Study Design: Cross-sectional. Setting: Online. Methods: An administered survey with questions asking about demographics, cancer history, treatment choices, and feelings about OSGs was posted on the 5 largest HNC OSGs on Facebook. Results: A total of 97 participants completed the survey. Mean age was 57.8 years old (standard deviation = 10.7 years). Most participants were female (50.5%) and Caucasian (92.8%). This cohort was well educated with 65.5% holding at least a college degree. Annual income was high with 41.8% reporting annual income of $100,000 or greater. The most common treatment modality was radiation (88.7%). The most common surgery was neck dissection (46.4%). Most participants preferred OSGs (70.8%) over other support group types. OSGs were heavily utilized with our cohort reporting using the OSG at least several times a week (80.0%). The top reasons for joining the OSG were sharing one's experience of HNC (76.3%) and gaining support from others with HNC (85.6%). OSGs were ranked as the #3 source of medical information for HNC behind otolaryngologists and oncologists. Membership in a HNC OSG had a minimal impact on decision-making. Conclusion: HNC OSGs appear to provide a beneficial community for HNC patients. Otolaryngologists should consider incorporating HNC OSG as a possible supplemental resource for their HNC patients.
