Sternocleidomastoid Tendon as a Consistent Landmark for Identifying the Spinal Accessory Nerve: A Case Series.

Objective: We propose a standardized approach of using the tendon of the sternocleidomastoid (SCM) muscle to locate the spinal accessory nerve (SAN) in neck dissection. Study Design: Cross-sectional anatomic study. Setting: Tertiary academic medical center. Methods: Adult patients aged ≥18 years undergoing primary neck dissection for head and neck cancer were included. Anatomic measurements included the length of the SCM tendon, the distance from the mastoid tip to the entrance of the SAN into the SCM, the distance from the SAN to the distal edge of the SCM tendon, and the perpendicular distance from the anterior edge of the SCM to the SAN. Five cadaveric specimens also underwent bilateral modified radical neck dissections with the same anatomic measurements taken. Results: Twenty-two living subjects and 5 cadavers were included. No statistical correlation was noted between patient demographics and any measurement. The mean (SD) length of the SCM tendon was 63.7 mm (11.8) in living subjects and 61.5 mm (10.4) in cadaveric specimens. The average distance from the mastoid tip to the entrance of SAN into the SCM was 51.6 mm (12.2) in living subjects and 51.6 mm (7.1) in cadaveric subjects. The distance of the SAN insertion into the SCM muscle from the anterior edge was 8.9 mm (3.4) in living subjects and 16.2 mm (7.2) in cadaver specimens. Laterality was compared in the cadaveric specimens; there was no statistically significant difference in any of the measurements between sides. Conclusion: This study demonstrates the SCM tendon to be a reliable and safe surgical landmark to identify and preserve the SAN during neck dissection.

The Adult Neck Mass: Predictors of Malignancy.

OBJECTIVE: Distinguishing benign from malignant adult neck masses can be challenging because data to guide risk assessment are lacking. We examined patients with neck masses from an integrated health system to identify patient and mass factors associated with malignancy. STUDY DESIGN: Retrospective cohort. SETTING: Kaiser Permanente Northern California. METHODS: The medical records of adults referred to otolaryngology in 2017 for a neck mass were evaluated. Bivariate and multivariable logistic regression analyses were performed. RESULTS: Malignancy was found in 205 (5.0%) of the cohort's 4103 patients. Patient factors associated with malignancy included sex, age, and race/ethnicity. Males had more than twice the odds of malignancy compared with females (adjusted odds ratio [aOR] = 2.38). Malignancy rates increased with age, ranging from 2.1% for patients younger than 40 years to 8.4% for patients 70 years or older. White non-Hispanic patients had 1.75 times the risk of malignancy compared with patients of other race/ethnicities. The percentage of patients with malignancy increased with increasing minimum mass dimension, from 3.0% in patients with mass size <1 cm to over 31% in patients with mass sizes 2 cm or larger (P < .0001). Imaging-based mass factors most highly predictive of malignancy included larger minimum mass dimension (≥1.5 cm vs <1.5 cm: aOR = 3.87), multiple masses (2 or more vs 1: aOR = 5.07), and heterogeneous/ill-defined quality (aOR = 2.57). CONCLUSION: Most neck masses referred to otolaryngology were not malignant. Increasing age, male sex, white non-Hispanic ethnicity, increasing minimum mass dimension, multiple neck masses, or heterogeneous architecture/ill-defined borders were associated with malignancy.

Academic and Gender Differences Among U.S. Otolaryngology Board Members.

OBJECTIVES: To determine the representation of women in leadership positions within otolaryngology societies and to compare their academic rank and research productivity to men. METHODS: The leadership positions of all U.S. otolaryngology societies were compiled. The Medicare Physician Compare database was used to obtain gender and medical school graduation year for all otolaryngologists. An online search was used to determine board member's academic faculty rank. The Scopus database was used to determine an individual's number of publications, citations, and h-index. All websites were accessed from July 2019 to October 2019. RESULTS: Of the 200 leadership positions, there were 160 unique individuals available for analysis. Of those, 23% were female. In comparison, 18% of all otolaryngologists in the United States are female. The average medical school graduation year was significantly more recent for female leaders (1997 vs. 1990, P < .001) than males, which is similar to all otolaryngologists (2001 vs. 1993, P < .001). Stratifying by gender alone, women averaged significantly fewer publications, citations, and h-indices compared to men (P < .05), and were also less likely to be professors (P < .01). When considering both gender and graduation year, significant differences among academic productivity were only noted for those graduating between 1990 to 1999. Among all board members who graduated after 2000, women comprised a majority of those in leadership positions (52%). CONCLUSION: Leadership positions in otolaryngology societies reflect the changing demographic of otolaryngologists in the United States. There is proportionate representation, and the more recently graduated female physicians show the same research productivity as their male counterparts.

'We need a safe, walkable way to connect our sisters and brothers': a qualitative study of opportunities and challenges for neighborhood-based physical activity among residents of low-income African-American communities.

OBJECTIVE: The purpose of this study was to explore perceptions of the benefits of and influencing factors for neighborhood-based physical activity (PA), and elicit suggestions for increasing neighborhood-based PA among primarily Black residents living in lower income neighborhoods. DESIGN: Eight focus groups were conducted in low-income, predominantly Black neighborhoods (n = 8) in Greenville, SC during Spring 2014. Using a semi-structured focus group guide with open-ended questions, residents were asked to describe benefits of PA, neighborhood factors associated with PA, and ways to increase PA within their neighborhoods. Trained research assistants transcribed audio recordings verbatim. Using grounded theory and an ecological perspective, emergent coding was employed to generate initial categories with open and axial coding used to achieve consensus on themes. RESULTS: Primarily Black (95%), female (72%), and older (M = 61.5 years) residents (N = 76) participated in the study. Seven themes were identified across the three main focus group topics: physical and mental health benefits of neighborhood PA, safety/hazards and social factors as influencing neighborhood PA, and improving safety, structural opportunities, and programing support to improve neighborhood PA. Most participants reported walking within their communities, despite describing several community-level barriers (e.g. drugs, safety). Residents desired structured neighborhood-based opportunities for increasing PA, including walking tracks and walking groups, and reported social benefits to being active, including increased awareness within the community and trust. Participants conveyed that walking strengthened the social environment of their community as well as the health of residents. CONCLUSION: Few studies of contextual factors and PA have focused on African-American, low-income neighborhoods. Despite diverse environmental constraints, residents reported walking within their communities as part of a healthy lifestyle. Social ecological interventions tailored to promote PA and reduce health disparities among residents of low-income communities should highlight neighborhood-based opportunities for PA, focusing on personal and collective social benefits of neighborhood walking.
