Early Weight-Bearing After Fibula Free Flap Surgery.

Importance: Despite the widespread use of fibula free flap (FFF) surgery for head and neck reconstruction, there are no studies assessing if early weight-bearing (EWB) affects postoperative recovery, and the timing of weight-bearing initiation following FFF surgery varies considerably across institutions. Therefore, it is important to understand the effect of EWB in these patients and whether it could improve postoperative recovery. Objective: To assess the association of EWB after FFF surgery with donor-site complications, length of stay, and discharge to home status. Design, Setting, and Participants: This retrospective cohort study took place at Massachusetts Eye and Ear, a single tertiary care institution in Boston, Massachusetts. A total of 152 patients who received head and neck reconstruction with a fibula osteocutaneous free flap between January 11, 2010, and August 11, 2022, were included. Exposure: EWB on postoperative day 1 vs non-EWB on postoperative day 2 or later. Main Outcomes and Measures: Patient characteristics, including demographic characteristics and comorbidities, surgical characteristics, donor-site complications, length of stay, and discharge disposition, were recorded. Descriptive statistics and multivariate logistic regressions were used to compute effect sizes and 95% CIs to compare postoperative outcomes in EWB and non-EWB groups. Results: A total of 152 patients (median [IQR] age, 63 [55-70] years; 89 [58.6%] male) were included. The median (IQR) time to postoperative weight-bearing was 3 (1-5) days. Among all patients, 14 (9.2%) had donor-site complications. EWB on postoperative day 1 was associated with shorter length of stay (adjusted odds ratio [AOR], 0.10; 95% CI, 0.02-0.60), increased rate of discharge to home (AOR, 7.43; 95% CI, 2.23-24.80), and decreased donor-site complications (AOR, 0.11; 95% CI, 0.01-0.94). Conversely, weight-bearing 3 or more days postoperatively was associated with an increased risk of pneumonia (AOR, 6.82; 95% CI, 1.33-34.99). Conclusions and Relevance: In this cohort study, EWB after FFF surgery was associated with shorter length of stay, increased rate of discharge to home, and decreased donor-site complications. These findings support the role of early mobilization to optimize postoperative recovery after FFF surgery.

Predictors of multiple dilations and functional outcomes after total laryngectomy and laryngopharyngectomy.

BACKGROUND: Following total laryngectomy (TL) or laryngopharyngectomy (TLP), patients may develop strictures that require multiple dilations to treat. However, the risk factors associated with dysphagia refractory to a single dilation are unknown. METHODS: Single-institution retrospective review of patients who underwent at least one stricture dilation after TL/TLP between March 2013 and March 2022. RESULTS: A total of 49 patients underwent stricture dilation after TL/TLP. Thirty-five (71%) underwent multiple dilations. Pharyngocutaneous fistula, primary chemoradiation therapy, and a shorter time interval from TL/TLP to first dilation were independently associated with dysphagia requiring multiple dilations. Patients in the multiple dilations group had a higher rate of limited diet and G-tube dependence compared to patients in the single dilation group. CONCLUSIONS: Shorter time interval to stricture formation is a prognostic indicator of the need for multiple dilations following TL/TLP. Patients requiring multiple dilations are at increased risk of persistent dysphagia long-term.

Depth of resection predicts loss of tongue tip sensation after partial glossectomy in oral tongue cancer: A pilot study.

OBJECTIVE(S): To characterize the change in sensory function following partial glossectomy for oral tongue cancer (OTC) and to identify predictors of loss of tongue-tip sensation (LoTTS). MATERIALS AND METHODS: Patients with at least three months follow-up after partial glossectomy for primary OTC were included. All patients underwent a qualitative tongue sensation assessment and an objective tongue sensory exam of the native tongue tip. Additional details regarding the oncologic resection, surgical reconstruction, and pathological stage were collected. Multiple linear and logistic regressions were used for statistical analysis. RESULTS: Sixty-four patients were enrolled, including 34 (53%) men with a median age of 65 at enrollment. Ten (15%) patients reported LoTTS. Increased depth of resection (DOR) was an independent predictor of LoTTS on multivariate analysis, with an increased risk at a threshold of 1.3 cm. LoTTS was also associated with worse subjective quality of life and perceptive speech performance in our qualitative tongue assessment. CONCLUSIONS: In this pilot study, we found that DOR is a critical prognostic factor in predicting post treatment function. Patients with an increased DOR, particularly above 1.3 cm, are at greatest risk of LoTTS and associated morbidity. These findings may be used to predict post-operative sensory deficits, manage patients' expectations, and optimize the reconstructive approach. Future studies are needed to validate and replicate our results.

Pedicled Forearm Fasciocutaneous Flap for Tracheal Reconstruction: Anomalous Radial Vasculature Preventing Free-Flap.

A 61-year-old female presented with poorly differentiated thyroid carcinoma with anterior tracheal wall invasion. Following resection, the patient was to undergo anterior tracheal wall reconstruction with a radial forearm fasciocutaneous free flap and costal cartilage grafts. However, intraoperative identification of a "brachioradial artery" was identified with the deep radial and ulnar arteries completely separated from the radial artery. To maximize the chance for flap success, the fasciocutaneous flap was converted to a pedicled rotational flap with excellent results. This is the first pedicled radial forearm fasciocutaneous flap for composite reconstruction of the anterior trachea.

Online Searches Related to Total Laryngectomy.

OBJECTIVE: To identify the most frequently asked questions regarding "laryngectomy" through an assessment of online search data. METHODS: Google Search data based on the search term "laryngectomy" were analyzed using Google Trends and Search Response. The most common People Also Ask (PAA) questions were identified and classified by the concept. Each website linked to its respective PAA question was rated for understandability, ease of reading, and reading grade level. RESULTS: Search popularity for the term "laryngectomy" remained stable between 2017 and 2022. The most popular PAA themes were post-laryngectomy speech, laryngectomy comparison to tracheostomy, stoma and stoma care, survival/recurrence, and post-laryngectomy eating. Of the 32 websites linked to the top 50 PAA's, eleven (34%) were at or below an 8th grade reading level. CONCLUSION: Post-laryngectomy speech, eating, survival, the stoma, and the difference between laryngectomy and tracheostomy are the most common topics searched online in relation to "laryngectomy." These are important areas for both patient and healthcare provider education. LEVEL OF EVIDENCE: N/A Laryngoscope, 133:2971-2976, 2023.

Postoperative opioid protocol: A 5-year resident-led effort to standardize prescribing patterns.

OBJECTIVES: The combined impact of variable surgeon prescribing preferences and low resident prescribing comfort level can lead to significant disparity in opioid prescribing patterns. We report an update on the expanded scope of this now 5-year, resident led initiative to standardize postoperative prescription practices within the Department of Otolaryngology. METHODS: With Institutional Review Board approval, performed a retrospective review of 12 months before (July 2016 - June 2017) and 48 months after (July 2019-June 2021) implementation of the Expanded Postoperative Analgesia Protocol. The Pre-Protocol and Expanded Protocol cohorts were compared using ANOVA, chi-squared and Fisher Exact tests, with ANCOVA and binary logistic regression for covariate analysis. Cost impact was calculated using average medication spending data for 2018-2019. RESULTS: 470 patients were included in the Pre-Protocol cohort (54 % male, mean age 35 years) and 679 in the Expanded Protocol cohort (63 % male, mean age 36 years). The protocol was effectively implemented as reflected in the reduction of combination opioid medications from 429 (91.3 %) to 26 (3.8 %) (87 % reduction, 95 % CI 86 % to 89 %, p < .001). The protocol resulted in a 66 % reduction in average morphine milligram equivalents per patient (333 mg to 114 mg, mean reduction 219 mg, 95 % CI 206 mg to 232 mg, p < .001), a 68 % reduction in medication refills (refill rate 20 % to 6 %; 14 % reduction, 95 % CI 12 % to 16 %, p < .001) and a 74 % reduction in cost of postoperative medications ($93.82 to $24.64 per patient). CONCLUSION: Through purposeful standardization, this 5-year resident led effort resulted in sustained changes to departmental wide prescribing practices yielding reduced variability, reduced cost, improved opioid management and superior pain control for postoperative patients.

Burn Pit Exposure Is Associated With Increased Sinonasal Disease.

OBJECTIVE: The aim of this study was to determine whether self-reported burn pit exposure is associated with increased subjective and objective sinus disease. DESIGN: A cross-sectional study was performed evaluating consecutive adult patients presenting to a US Military rhinology clinic. Demographics, medical histories, sinonasal quality-of-life scores, and nasal endoscopy examinations were obtained. Participants were divided into three cohorts based on self-reported exposure histories and outcomes compared. RESULTS: One hundred eighty-six patients met the inclusion criteria, the majority of whom were male. Patients with burn pit exposure had worse Sinonasal Outcome Test-22 scores (49.9) compared with those deployed without burn pit exposure (31.8) or never deployed (31.5). Endoscopic findings demonstrated worse disease within those exposed (Lund-Kennedy score, 3.3) compared with the other cohorts (1.8 and 1.7, respectively). CONCLUSIONS: These novel findings suggest that deployment-related burn pit exposure is associated with increased subjective and objective sinus disease.

Prediction of Thyroid Hormone Replacement Following Thyroid Lobectomy: A Long-term Retrospective Study.

OBJECTIVE: Following thyroid lobectomy, patients are at risk for hypothyroidism. This study sought to determine the incidence of postlobectomy thyroid hormone replacement as well as predictive risk factors to better counsel patients. STUDY DESIGN: Retrospective cohort study. SETTING: Patients aged 18 to 75 years treated in a single academic institution who underwent thyroid lobectomy from October 2006 to September 2017. METHODS: Patients were followed for an average of 73 months. Demographic data, body mass index, size of removed and remnant lobe, preoperative thyroid-stimulating hormone (TSH) level, final thyroid pathology, and presence of thyroiditis were collected and analyzed. Risk factors were evaluated with chi-square analyses, t tests, logistic regression, and Kaplan-Meier analysis. RESULTS: Of the 478 patients reviewed, 369 were included in the analysis, 30% of whom eventually required thyroid hormone replacement. More than 39% started therapy >12 months postoperatively, with 90% treated within 36 months. Patient age ≥50 years and preoperative TSH ≥2.5 mIU/L were associated with odds ratios of 2.034 and 3.827, respectively, for thyroid hormone replacement. Malignancy on final pathology demonstrated an odds ratio of 7.76 for hormone replacement. Sex, body mass index, volume of resected and remaining lobes, and weight of resected lobe were not significant predictors. CONCLUSION: Nearly a third of patients may ultimately require thyroid hormone replacement. Age at the time of surgery, preoperative TSH, and final pathology are strong, clinically relevant predictors of the need for future thyroid hormone replacement. After lobectomy, patients should have long-term thyroid function follow-up to monitor for delayed hypothyroidism.

COVID-19 Preprocedural Testing: What About the False Positives?

In the COVID-19 era, preprocedural patients are almost uniformly screened for symptoms, asked to quarantine preoperatively, and then undergo a test of uncertain validity with very low pretest probability. A small percentage of these tests return positive. As a result, surgical procedures are delayed and patients are required to quarantine. Are these asymptomatic patients truly positive for COVID-19? What are the impacts of these test results on the patient and the health care system? In the following commentary, we review how the uncertain validity of reverse transcription polymerase chain reaction testing combined with a low-prevalence population predisposes for false-positive results. As a mitigation strategy, we ask that readers refocus on the fundamental principal of diagnostic testing: pretest probability.

Postoperative Analgesia Protocol: A Resident-Led Effort to Standardize Opioid Prescribing Patterns.

OBJECTIVES: The combined impact of variable surgeon prescribing preferences and low resident prescribing comfort level can lead to significant disparity in opioid prescribing patterns for the same surgery in the same academic surgical practice. We report the results of a resident led initiative to standardize postoperative prescription practices within the Department of Otolaryngology at a single tertiary-care academic hospital in order to reduce overall opioid distribution. STUDY DESIGN: Retrospective cohort study. METHODS: Following approval by the Institutional Review Board, performed a retrospective review of 12 months before (July 2016-June 2017) and after (July 2017-June 2018) implementation of the Postoperative Analgesia Protocol, which included all adults undergoing tonsillectomy, septoplasty, thyroidectomy, parathyroidectomy, tympanoplasty, middle ear exploration, stapedectomy, and ossicular chain reconstruction. RESULTS: Seven hundred and thirty eight procedures met inclusion criteria. Following implementation, total morphine milligram equivalents decreased by 26% (P < .0001). The number of patients requiring opioid refills decreased by 49%, and morphine milligram equivalents received as refills decreased by 16% (P < .001). Thyroid and parathyroid surgery had the greatest reduction in morphine milligram equivalents prescribed (84%, P < .001), followed by septoplasty (30%, P = .001) and tonsillectomy (18%, P < .001). The number of patients receiving refills of opioid medications decreased for all procedures (tonsillectomy 54%; septoplasty 67%; thyroid/parathyroid surgery 80%, middle ear surgery 100%). CONCLUSIONS: While every patient and surgery must be treated individually, this study demonstrates that a resident led standardization of pain control regimes can result in significant reductions in total quantity of opioids prescribed. LEVEL OF EVIDENCE: IV Laryngoscope, 131:982-988, 2021.

Airway Management of COVID-19 Positive Patients Aboard USNS COMFORT Mission to New York City.

During the USNS Comfort mobilization to New York City in response to the pandemic, the ship's medical team cared for over 35 mechanically ventilated corona virus disease 2019 (COVID-19) infected patients. Due to the better than expected mortality rates of these patients, tracheotomy for prolonged intubation or other indicated interventional bronchoscopies were performed on 7 COVID positive patients, as well as 2 with negative screening tests. No member of the health care team subsequently became symptomatic or tested positive for COVID-19. This was in part due to the formation of a dedicated surgical airway team, use of standardized procedural techniques and personal protective equipment (PPE), and construction of a negative pressure operating room within the COVID-19 isolation ward on the ship. This experience shows that tracheotomies and other aerosolizing procedures can be performed with due concern for patient and provider safety, regardless of patient's COVID status.

Hybrid Surgical Simulator: A Temporal Bone Simulator Validation Study of the Stryker Surgical Simulator (S3).

INTRODUCTION: The Stryker Surgical Simulator is a hybrid, temporal bone simulator that uses both tactile and haptic feedback combined with a computer interface. We sought to validate this simulator as an otolaryngology resident training tool for performing tympanomastoidectomy. MATERIALS AND METHODS: 15 residents and staff performed five basic cortical mastoidectomies. Staff surgeons comprised the "expert" cohort and resident surgeons comprised the "trainee" cohort. Subjective evaluation of the face validity and content validity was assessed via pre- and postquestionnaires. Objective evaluation of content validity was assessed through grading of each temporal bone dissection specimen, comparing time to task completion, and calculating the rate of injury to critical structures. Study approved by the Institutional Review Board (2013.0001). RESULTS: Post hoc questionnaires showed that both staff and residents subjectively rated the simulator favorably on face validity, content validity, and all global assessment categories, though there were no significant distinctions between groups (P > 0.05). The resident group had a significantly longer drilling time compared with the staff group throughout the series of tympanomastoidectomies (P = 0.008), and both groups showed a decrease in time to task completion with repetitive drilling. However, there were no significant differences in surgical performance as evaluated by a blinded senior neurotologist (P = 0.52). There were also no critical injuries recorded by the simulator in any of the 75 trials, preventing any evaluation on this measure. CONCLUSIONS: Despite favorable subjective evaluations by both staff and residents, objective discrimination between experienced and novice participants was not achieved. This was likely in part due to inherent design flaws of the simulator. This emphasizes the potential shortcomings of surgical simulation models for highly technical procedures and points to the importance of intensive study and validation prior to incorporation of commercial training models into surgical training programs.

Toward Sustainable Environmental Quality: Priority Research Questions for North America.

Anticipating, identifying, and prioritizing strategic needs represent essential activities by research organizations. Decided benefits emerge when these pursuits engage globally important environment and health goals, including the United Nations Sustainable Development Goals. To this end, horizon scanning efforts can facilitate identification of specific research needs to address grand challenges. We report and discuss 40 priority research questions following engagement of scientists and engineers in North America. These timely questions identify the importance of stimulating innovation and developing new methods, tools, and concepts in environmental chemistry and toxicology to improve assessment and management of chemical contaminants and other diverse environmental stressors. Grand challenges to achieving sustainable management of the environment are becoming increasingly complex and structured by global megatrends, which collectively challenge existing sustainable environmental quality efforts. Transdisciplinary, systems-based approaches will be required to define and avoid adverse biological effects across temporal and spatial gradients. Similarly, coordinated research activities among organizations within and among countries are necessary to address the priority research needs reported here. Acquiring answers to these 40 research questions will not be trivial, but doing so promises to advance sustainable environmental quality in the 21st century.

Multicenter prospective evaluation of the reliability of the combined use of two models to predict non-sentinel lymph node status in breast cancer patients with metastatic sentinel lymph nodes: the MSKCC nomogram and the Tenon score. Results of the NOTEGS study.

BACKGROUND: The purpose of this study was to prospectively evaluate the combined use of The Memorial Sloan Kettering Cancer Center nomogram and Tenon score to select, in patients with metastatic sentinel lymph node (SN), those at low risk of metastatic non-SN for whom additional axillary lymph node dissection (ALND) could be avoided. METHODS: From January 2011 to July 2012, a prospective non-interventional nationwide study was conducted (NCT01509963). We sought to identify the false reassurance rate (FRR, a negative test result is false) in patients with both a ⩽10% probability of metastatic non-SN with the MSKCC nomogram and a Tenon score ⩽3.5 (low risk): the proportion of patients with metastatic non-SN at additional ALND. Our hypothesis was that these patients would have a FRR⩽5%. RESULTS: Data on 2822 patients with breast cancer from 53 institutions were prospectively recorded. At least one SN was metastatic (isolated tumour cells, micro- or macrometastases) in 696 patients (24.7%). Among patients with ALND and complete data to calculate combined risk (n=504), 67 and 437 patients had low and high combined risk, respectively. Patients at low risk had less ALND (47%) compared to patients at high risk (P<0.001). This study did not meet its primary objective because the FRR in patients with low risk was 16.4% (11 out of 67) (95% confidence interval (CI): 9.7-23.1%). In the high-risk group, 33.9% (148 out of 437) (95% CI: 29.6-38.4%) had non-SN metastases (P=0.004). CONCLUSIONS: In this controlled prospective study, metastatic SN patients with both a ⩽10% probability of metastatic non-SN with the MSKCC nomogram and a Tenon score ⩽3.5 failed to identify patients at low risk of metastatic non-SN when completion ALND was not systematic.

Olfactory Neuroblastoma with Divergent Differentiation: An Unusual Histologic Finding in a Rare Tumor.

Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal tract that arises from olfactory epithelium. There have been reports, mainly in tumors treated with chemoradiation or with distant metastases, describing focal histologic changes of divergent cell populations within archetypal ONB. Only three cases have been reported of ONB coexisting with non-neuroendocrine tumors. We describe our experience with a 35-year-old male with a nasal cavity mass extending into the anterior cranial fossa. Pathology revealed this to be a high grade malignant neoplasm with features of olfactory neuroblastoma and a significant divergent population of pancytokeratin and epithelial membrane antigen-reactive cells. The patient underwent combined endoscopic and open craniofacial resection followed by adjuvant chemoradiation. We describe the clinical presentation, treatment, and outcome followed by a review of the literature. Surgical pathology clearly demonstrated two cell populations evenly distributed and displaying classic histologic and immunohistochemical markers of ONB, as well as poorly differentiated cells with an epithelial immunophenotype. The patient is now 16 months status post completion of treatment with no evidence of recurrence. Our patient's presentation is unique and unusual in that the tumor demonstrated a high grade olfactory neuroblastoma and a divergent, epithelial-marker reactive cell population in the same tumor. This combined appearance is unusual and may represent an "olfactory carcinoma". Only one previous case has reported carcinomatous involvement of an ONB. There is insufficient information in the literature to draw conclusions on the impact these divergent cell populations have on prognosis or treatment.
