Using a Novel Method to Quantify and Confirm the Variable Vertical Vector of the Deep Plane Facelift.

Background: In deep plane rhytidectomy, it is accepted that a more vertical vector will lead to a more natural rejuvenated look than a horizontal vector of pull. Objective: Among patients undergoing deep plane rhytidectomy, can skin angle measurements designed by the authors be used as a proxy for vector of tension to confirm a vertical vector? Methods: Case series measuring the rhytidectomy vector of pull for a series of patients performed by a single surgeon. Results were compared between the vectors of the pre- and postauricular flaps as well as comparing the vector of pull in male versus female patients, patients undergoing facelift alone versus in conjunction with other rejuvenation procedures, and between primary versus revision rhytidectomy patients. Results: Patient characteristics: Average age 64.4 (range 47-79), predominantly female (26/28, 92.9%), primary rhytidectomy (24/28, 85.7%), with concomitant brow lift (12/28, 42.9%). Results reveal a more vertical than horizontal vector of pull on both the pre- and postauricular superficial musculoaponeurotic system flaps with the vector of the anterior flap being more vertical than that of the posterior flap. Conclusion: Utilizing a novel proxy measurement, the vector of pull of the deep plane facelift was more vertical than horizontal.

Correlating the Bony Facial Trauma Score with Clinical Outcomes.

Background: In 2017, the Bony Facial Trauma Score (BFTS) was developed to quantify and describe bony trauma of the face. Objective: To compare BFTSs for the need of hospital admission, intensive care unit (ICU) admission, surgery, tracheostomy tube placement, cervical spine (c-spine) injury, and mortality. Methods: A retrospective review of patients sustaining bony facial trauma from January 1, 2017 to November 30, 2019 was done. Logistic regression modeling measured the association between BFTS and admission status, need for operative repair, tracheostomy, mortality, ICU admission, and c-spine injury. Results: Three hundred six patients were included for this analysis. Median BFTS was 3.5 (interquartile range, 5), while the average age was 45.0 years (standard deviation, 22.3). The most common mechanisms of injury were motor vehicle accident (44.8%) and ground-level fall (32.5%). BFTS was found to correlate with the following (p < 0.05): admission (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.01-1.13), mortality (OR 1.05, 1.00-1.10), tracheostomy (OR 1.11, 1.07-1.17), operative management (OR 1.16, 1.11-1.22), ICU (OR 1.07, 1.03-1.11), and c-spine injury (OR 1.05, 95% CI 1.03-1.11). Conclusion: A significant correlation was found between BFTS and all the outcomes investigated.

An Internally Validated Prognostic Risk-Score Model for Disease-Specific Survival in Clinical Stage I and II Merkel Cell Carcinoma.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare cutaneous malignancy for which factors predictive of disease-specific survival (DSS) are poorly defined. METHODS: Patients from six centers (2005-2020) with clinical stage I-II MCC who underwent sentinel lymph node (SLN) biopsy were included. Factors associated with DSS were identified using competing-risks regression analysis. Risk-score modeling was established using competing-risks regression on a training dataset and internally validated by point assignment to variables. RESULTS: Of 604 patients, 474 (78.5%) and 128 (21.2%) patients had clinical stage I and II disease, respectively, and 189 (31.3%) had SLN metastases. The 5-year DSS rate was 81.8% with a median follow-up of 31 months. Prognostic factors associated with worse DSS included increasing age (hazard ratio [HR] 1.03, p = 0.046), male sex (HR 3.21, p = 0.021), immune compromise (HR 2.46, p = 0.013), presence of microsatellites (HR 2.65, p = 0.041), and regional nodal involvement (1 node: HR 2.48, p = 0.039; ≥2 nodes: HR 2.95, p = 0.026). An internally validated, risk-score model incorporating all of these factors was developed with good performance (AUC 0.738). Patients with ≤ 4.00 and > 4.00 points had 5-year DSS rates of 89.4% and 67.2%, respectively. Five-year DSS for pathologic stage I/II patients with > 4.00 points (n = 49) was 79.8% and for pathologic stage III patients with ≤ 4.00 points (n = 62) was 90.3%. CONCLUSIONS: A risk-score model, including patient and tumor factors, based on DSS improves prognostic assessment of patients with clinically localized MCC. This may inform surveillance strategies and patient selection for adjuvant therapy trials.

Predictors of False Negative Sentinel Lymph Node Biopsy in Clinically Localized Merkel Cell Carcinoma.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is routinely recommended for clinically localized Merkel cell carcinoma (MCC); however, predictors of false negative (FN) SLNB are undefined. METHODS: Patients from six centers undergoing wide excision and SLNB for stage I/II MCC (2005-2020) were identified and were classified as having either a true positive (TP), true negative (TN) or FN SLNB. Predictors of FN SLNB were identified and survival outcomes were estimated. RESULTS: Of 525 patients, 28 (5.4%), 329 (62.7%), and 168 (32%) were classified as FN, TN, and TP, respectively, giving an FN rate of 14.3% and negative predictive value of 92.2% for SLNB. Median follow-up for SLNB-negative patients was 27 months, and median time to nodal recurrence for FN patients was 7 months. Male sex (hazard ratio [HR] 3.15, p = 0.034) and lymphovascular invasion (LVI) (HR 2.22, p = 0.048) significantly correlated with FN, and increasing age trended toward significance (HR 1.04, p = 0.067). The 3-year regional nodal recurrence-free survival for males >75 years with LVI was 78.5% versus 97.4% for females ≤75 years without LVI (p = 0.009). Five-year disease-specific survival (90.9% TN vs. 51.3% FN, p < 0.001) and overall survival (69.9% TN vs. 48.1% FN, p = 0.035) were significantly worse for FN patients. CONCLUSION: Failure to detect regional nodal microscopic disease by SLNB is associated with worse survival in clinically localized MCC. Males, patients >75 years, and those with LVI may be at increased risk for FN SLNB. Consideration of increased nodal surveillance following negative SLNB in these high-risk patients may aid in early identification of regional nodal recurrences.

Potential for health care cost savings with preoperative gastrostomy tube placement in the head and neck cancer population.

BACKGROUND: The purpose of this study was to examine the cost differences between preoperative and postoperative placement of gastrostomy tubes (G-tubes) in patients with head and neck cancer. METHODS: We conducted a retrospective chart review of patients with aerodigestive tract cancers from 2010 to 2015. Data included inpatient and postdischarge costs, demographics, tumor characteristics, surgical treatment, length of stay (LOS), time spent in the intensive care unit (ICU), and readmissions. RESULTS: Five hundred ninety patients were included in this study. There was a $7624 inpatient cost savings (P = .002) for those G-tubes placed preoperatively ($26 060) versus postoperatively ($33 754). Postdischarge costs did not differ significantly between groups (P = .60). There was a $9248 total costs savings (P = .009) for those patients with G-tubes placed preoperatively ($39 751) versus postoperatively ($48 999), despite patients with preoperative G-tubes having lower body mass index (BMI; P = .009), higher Association of Anesthesiologist (ASA) class (P = .02), more preoperative radiation (P < .001), and more free tissue transfer reconstruction (P = .007). CONCLUSION: There is potential for savings by placing G-tubes preoperatively, possibly driven by decreased LOS, despite data suggesting that patients with G-tubes placed preoperatively are higher risk.

Anatomical Variations of the Transverse-Sigmoid Sinus Junction: Implications for Endovascular Treatment of Idiopathic Intracranial Hypertension.

Venous sinus pathology can result in multiple pathological diseases, including idiopathic intracranial hypertension (IIH). There remains a paucity of information on anatomical luminal variations of the major venous sinuses which may contribute to the etiology of certain disease states. Thirty-six transverse and sigmoid sinuses were removed following dissection of 19 unfixed cadaveric heads. Sinuses were opened longitudinally to study luminal variations. A semiquantitative classification system was developed to assess septations and blind pouches. Seventy-nine percent of cadavers had a luminal anatomical variation. Forty-four percent and 42% of sinuses dissected had occurrence of a septations or blind pouches, respectively. Thirty percent of septations and 25% of pouches were classified as large. Incidence of anatomical variations was not statistically significant between cadaver gender or sinus laterality. Luminal variations are present in the transverse and sigmoid sinuses at rates higher than expected. This study is the first to report the presence of blind pouches in the luminal wall of transverse and sigmoid sinuses. These variations can have clinical importance to the endovascular surgeon and may also contribute to the pathophysiological etiology of venous sinus diseases.
