The effect of transfusion on survival in head and neck cancer after free tissue reconstruction.

Objective: To examine if perioperative blood transfusion affects overall survival (OS) and recurrence-free survival (RFS) in head and neck cancer patients who undergo free tissue reconstruction. Design: Retrospective cohort study. Methods: The medical records of free tissue flaps between 2007 and 2010 were reviewed. Differences in demographics and clinical factors based on the level of transfused packed red blood cells (PRBC) were examined using chi-squared tests, Kruskal-Wallis tests, and/or ANOVA tests. Survival time was compared using a Cox proportional hazard model. Results: Data were available for 183 patients. Patients who had PRBC transfusion significantly differed from the non-transfused group by flap type, flap with bone, Charlson Comorbidity Index (CCI), and hemoglobin and hematocrit. When stratified into three groups based on units of PRBC; flap type, flap with bone, CCI, preoperative hemoglobin, and hematocrit were found to differ significantly. The 2-year Kaplan-Meier plot demonstrated improved OS for those who did not receive any PRBC transfusion. The use of more than 3 units of blood decreased 2-year OS significantly when compared to the non-transfused group. Finally, after adjusting for CCI using a Cox proportional hazard model, survival was significantly affected by CCI. Conclusion: After controlling for patient age, oncologic stage, cancer subsite, histology, type of free flap, vascularized bone-containing flap, recurrence type, CCI, and preoperative hemoglobin and hematocrit, patients who received 3 or more units of PRBC in the perioperative period had significantly decreased OS. RFS did not differ between the transfused versus non-transfused groups. Level of Evidence: Level 4.

Managing Oromandibular Hardware Failure after Free Flap Surgery.

Hardware failure after oromandibular reconstruction using free tissue transfer can delay additional therapies directed at cancer treatment and prevent patients from returning to normal oral function. Understanding and strict adherence to principles of rigid fixation is critical in preventing complications. Early surgical intervention for hardware exposure as well as utilization of locoregional flaps may prevent the need for more extensive revision surgery.

Peritonsillar Abscess Simulator: A Low-Cost, High-Fidelity Trainer.

Audience: Our reusable low-cost peritonsillar abscess simulator (PTA) simulator is designed to train emergency medicine (EM) residents, fellows, and medical students. Trainees who are interested in otolaryngology (OTL) or this specific disease may also benefit from this simulator. Introduction: Peritonsillar abscess is one of the most common deep infections 1 of the head and neck, accounting for 7589 consultations and 11069 hospital bed days in the UK between 2009-2010.1,2 Emergency medicine physicians commonly treat this pathology with surgical and medical modalities. Not only is this a common diagnosis, but there is a significant cost associated with the evaluation and management of primary PTA. 3Demands for high-volume patient care and good patient outcomes are increasing in a medical climate of limited financial resources and resident work hours. Given these complexities, medical education is viewing simulation training, with proven success in various surgical specialties, as a valuable addition to resident education and patient safety. 3-5The PTA is the collection of pus in the space between the palatine tonsil and its capsule. Successfully locating the abscess is crucial because it prevents the unwanted damage of nearby vascular structures, patient discomfort, and failure to treat the infection. Management of peritonsillar abscess is primarily surgical and includes incision and drainage (I & D), needle aspiration, or Quinsy tonsillectomy.The simulator provides a realistic characteristic of typical PTA presentations, such as uvula deviation, swelling, trismus, and purulence during aspiration. While learning to drain a PTA, trainees must locate the infection with a needle without injury to the surrounding structures of the oral cavity and deep structures of the neck. The discomfort caused during this procedure can be unsettling for both physician and patient. Simulation use and testing enable the trainee to develop familiarity with handling instruments, increase comfort with the sequence of a procedure, and improve confidence in the ability to perform a procedure safely.6,7,8 Simulators provide improved patient outcomes and increased EM residents' comfort level. Educational Objectives: By the end of this training session, learners will be able to: 1) locate the abscess, 2) perform needle aspiration, and 3) develop dexterity in maneuvering instruments in the small three-dimensional confines of the oral cavity without causing injury to local structures. Educational Methods: Our PTA simulator was fabricated with a low-cost, non-degradable material and is the first known PTA simulator that used a validated survey for fidelity assessment. The simulator was fabricated using a silicone mold to mimic the oral cavity and oropharynx. A simulated abscess pocket consisting of saline encased in balloon material was placed in the proper anatomic location, allowing for abscess simulation on either side of the oropharynx model. The time to fabricate the model averaged 20 hours. The simulator was manufactured with low-cost materials at an expense of 45 USD and could be easily reproduced by any EM residency program. Research Methods: Twenty-one participants were instructed to expose and drain the simulated abscess. The model was evaluated using The Michigan Standard Simulation Experience Scale (MiSSES).7 Participants scored the simulator in five categories: Self-efficacy, fidelity, educational value, teaching quality, and the overall rating on a 5-point Likert scale of simulator. Overall rating and global evaluation scores were compared by groups (Group 1, Group 2) between training level (residents and attendings), specialty (emergency and otolaryngology), and previous experience (<5 or ≥5 drainages).Convenience sampling was used to determinate the sample. Variables were summarized using the mean and standard deviation for continuous variables and percentages and frequencies for categorical variables. The MiSSES was scored as previously described in the literature.7 The Kolmogorov-Smirnov test was used to test for normal distribution of the variables. T-test for independent samples was performed to determinate if there exists a difference between groups in perception of a PTA simulator. The statistical analyses were performed using SPSS version 20.0 Armonk, NY: IBM. Results: Twenty-one participants were enrolled in the study: residents (n=15) and attending (n=6) from OTL and EM departments. The simulator's plasticity allowed multiple attempts of needle aspiration and drainage without degradation and received high ratings on teaching quality, fidelity, and educational value. This PTA simulator achieved high fidelity ratings in the standard simulator's assessment survey for realism of environment, simulation of trismus, uvular deviation, and realism of the mucosal surfaces. On the MiSSES, the model received positive ratings (range 3.6 to 4.9). The highest rating was on teaching quality (4.9), fidelity (4.6), and educational value (4.5) (Table 1). We found that self-efficacy and teaching quality sections were rated higher for those who had less experience (≥5 PTA drainage), while fidelity was rated higher for OTL. The overall rating average was 4 and was higher of attendings, OTL, and those with less experience. All comparisons between groups were not statically significant (Table 2). About 76% of participants found that the simulator can be used in training with slight improvement or no improvement needed. (Table 3). Discussion: With favorable participant ratings and comments, we believe that this tool can offer high-fidelity simulation at a low cost. Widespread use may be possible, allowing training of EM residents in performing instrumentation of PTA in a controlled simulation environment. We have created a reusable low-cost PTA simulator that achieved a high score fidelity in a standard simulator's assessment survey. Topics: Peritonsillar abscess, oropharynx, emergency medicine residency, otolaryngology residency training.

A Report on the Use of Telehealth in Otolaryngology in the Pre COVID-19 Era.

Objective: To investigate the integration of and barriers to the utilization of telehealth technology and its components (telemedicine, e-Health, m-health) in daily otolaryngologic practice before the SARS CoV-2 (COVID-19) pandemic. Methods: This cross-sectional study was conducted at a tertiary academic center. A national survey of members of the American Academy of Otolaryngology-Head and Neck Surgery was administered. Descriptive analyses were performed to determine how telehealth was employed in otolaryngologists' practices. Results: A total of 184 surveys were completed. Telehealth technology was used by 50% of otolaryngologists surveyed. Regions with the largest percentage of physicians using telehealth were the Mid-Atlantic region (84%) and West Coast (67%). Most otolaryngologists indicated that they were familiar with telehealth or any of its components and how it is used in practice (52-83%), they had heard of telehealth or any of its components but were unsure what the terms specifically entailed (17-42%); 53% were satisfied with their current use of telehealth and electronic medical record (EMR); and 72% were comfortable utilizing smart devices for patient care. Most otolaryngologists (65%) indicated reimbursement as the biggest limitation to implementing telehealth, and 67% believed that typing was a hindrance to EMR utility. Conclusion: Half of the surveyed otolaryngologists used some form of telehealth at the time of the survey. The most commonly cited obstacle to physician adoption of telehealth was reimbursement. Although the adoption of telehealth technology was still limited in the field of otolaryngology based on this study, we are now seeing significant change due to the COVID-19 pandemic.

Improving access and timeliness of care for veterans with head and neck squamous cell carcinoma: A multidisciplinary team's approach.

OBJECTIVES/HYPOTHESIS: With the prevalence of head and neck squamous cell carcinoma (HNSCC) nearly twice as high in veterans (6%) than general populations (3%), the noted problems of long waits and access to care in United States Veterans Affairs (VA) hospitals across the country are pressing. We examined primary outcome measures of timeliness and access to care for our patients with HNSCC assessing a multidisciplinary team approach at our VA hospital. STUDY DESIGN: Retrospective chart review. METHODS: Our patients newly diagnosed with HNSCC were identified from two 24-month periods: diagnosis before (group 1, 2005-2006) and after (group 2, 2008-2009) implementing our multidisciplinary team in 2007. No significant differences in age (P = .13) or disease stage (P = .18) occurred between groups. Primary and secondary outcomes (i.e., treatment modality, imaging, completion of treatment, survival) were compared. RESULTS: Timeliness to care improved for all measures. Improvement was significant for times from consult placed to seen in clinic (27.5-16.5 days; P < 0.0001) and from positive biopsy reported to date of initiating definitive treatment (35-27 days; P = 0.04). Pretreatment consults to various services represented by the multidisciplinary team increased from one to four (P < 0.0001). Two-year mortality was approximately the same between group 1 (33%) and group 2 (36%) (P = 0.035). Five-year mortality was slightly better in group 2 (50%) versus group 1 (61%), although not statistically significant. CONCLUSION: Our veteran population with HNSCC had improved timeliness and access to care with our multidisciplinary approach. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:627-631, 2016.

IRAK1 is a novel DEK transcriptional target and is essential for head and neck cancer cell survival.

The chromatin-binding DEK protein was recently reported to promote the growth of HPV+ and HPV- head and neck squamous cell carcinomas (HNSCCs). Relevant cellular and molecular mechanism(s) controlled by DEK in HNSCC remain poorly understood. While DEK is known to regulate specific transcriptional targets, global DEK-dependent gene networks in HNSCC are unknown. To identify DEK transcriptional signatures we performed RNA-Sequencing (RNA-Seq) in HNSCC cell lines that were either proficient or deficient for DEK. Bioinformatic analyses and subsequent validation revealed that IRAK1, a regulator of inflammatory signaling, and IRAK1-dependent regulatory networks were significantly repressed upon DEK knockdown in HNSCC. According to TCGA data, 14% of HNSCC specimens overexpressed IRAK1, thus supporting possible oncogenic functions. Furthermore, genetic or pharmacologic inhibition of IRAK1 in HNSCC cell lines was sufficient to attenuate downstream signaling such as ERK1/2 and to induce HNSCC cell death by apoptosis. Finally, targeting DEK and IRAK1 simultaneously enhanced cell death as compared to targeting either alone. Our findings reveal that IRAK1 promotes cell survival and is an attractive therapeutic target in HNSCC cells. Thus, we propose a model wherein IRAK1 stimulates tumor signaling and phenotypes both independently and in conjunction with DEK.

Double deep inferior epigastric arteries encountered during vertical rectus abdominis flap harvest: a case report and literature review.

The rectus abdominis flap offers a number of advantages over other flaps used in head and neck reconstruction. The flap can be harvested by a separate team and can be tailored to include skin, muscle, and fat. In addition, the available vascular pedicle is long and its large caliber provides an appropriate size match with recipient neck vessels. Central to reconstructive success is defining an arterial and venous pedicle that provides balanced perfusion to all components of the flap. Anomalous vascular anatomy presents principal challenges in reestablishing free flap perfusion. We present a case of double, right deep inferior epigastric arteries encountered during vertical rectus abdominis myocutaneous flap reconstruction of the tongue and floor of the mouth and discuss the clinical outcomes of this reconstruction.

Sexuality after treatment of head and neck cancer: findings based on modification of sexual adjustment questionnaire.

OBJECTIVES/HYPOTHESIS: Evaluate sexual dysfunction in patients after treatment for head and neck cancer. STUDY DESIGN: Single-institution cross-sectional study. METHODS: Our modified Sexual Adjustment Questionnaire was administered to 42 patients (mean age, 55.1 years) and included seven questions (total score, 7-35). Based on sexual satisfaction ratings, we categorized three groups as unsatisfied (7-16), satisfied (17-25), and very satisfied (26-35). Clinical information was obtained by reviewing medical records. Bivariate analysis tested associations between sexual satisfaction and patient-related factors (e.g., sex, age, site/cancer stage, treatment, time between treatment and survey, partner, alcohol/tobacco consumption). Pearson correlation was used to analyze two continuous variables, and multivariate logistic regression analysis was used to evaluate the independent impact of each factor. RESULTS: All 42 patients rated that head and neck cancer negatively impacted their sexual relationships, including 21 (50%) rating effects as negative or extremely negative. Men reported higher satisfaction scores with sexual function (mean ± standard deviation) than women (19.9 ± 5.0 vs. 16.3 ± 6.5, respectively; P = .06). Respondents with partners reported higher scores than those without partners (19.9 ± 5.3 vs. 14.1 ± 4.4, respectively; P = .01). When the survey was administered (median, 12 months; range, 4-33 months) after the first treatment, mean score was 19; 57% of respondents were sexually satisfied, 31% were unsatisfied, and 12% were very satisfied. Instrument reliability was .82 (Cronbach alpha). CONCLUSIONS: Patients who are male and ≤ 60 years have a higher probability of sexual satisfaction during recovery. Our sexual dysfunction questionnaire will be administered in further prospective studies in patients with head and neck cancer.

Inpatients with gunshot wounds to the face.

Microvascular free tissue transfer (FTT) is an increasingly used method of reconstruction for traumatic defects of the head and neck. We describe the immediate management, FTT reconstruction techniques, and outcomes of 6 individuals who sustained maxillofacial gunshot trauma and were treated at a single tertiary-care level I trauma center. All 6 patients were white men with a mean age of 33 years. The mandible, nose, and orbital contents were the most frequently affected critical structures. All patients initially underwent primary wound debridement and tracheostomy, with concurrent maxillomandibular wire fixation and/or midface or mandible plate fixation in 5 patients. The mean time from injury to definitive FTT was 38 days. Five patients underwent fibula osteocutaneous FTT and 1 underwent radial forearm fasciocutaneous FTT. One patient also underwent concurrent local tissue rearrangement and pedicled flap surgery for nasal reconstruction. The mean hospital length of stay after FTT was 6 days. All FTT survived without necrosis. Oral incompetence and poor cosmesis from undesirable scarring patterns were the most common long-term complications. In summary, successful reconstruction of head and neck defects caused by gunshot trauma begins with airway stabilization, wound management, and bony fracture reduction and fixation. Definitive microvascular FTT is a useful method of repairing traumatic head and neck defects, although long-term functional and cosmetic complications may still occur.

Perioperative management of obstructive sleep apnea: a survey of Veterans Affairs health care providers.

OBJECTIVES/HYPOTHESIS: (1) To determine the presence of Veterans Affairs (VA) institutional guidelines for the perioperative management of obstructive sleep apnea (OSA); (2) to examine current use of preoperative screening tools for OSA in the VA; and (3) to understand current VA practice patterns regarding postoperative disposition of patients with OSA. STUDY DESIGN: Survey study. SETTING: Veterans Affairs hospitals with surgical services; sample size 102 facilities. SUBJECTS: Veterans Affairs health care providers. METHODS: The authors surveyed health care providers at VA hospitals using a survey tool developed by the authors. RESULTS: The response rate was 80%. A variety of preoperative screening tools for OSA were used by respondents, most commonly American Society of Anesthesiologists guidelines (53%). A policy for postoperative disposition of known and presumed OSA was present in 26% and 19% of responses, respectively. Of those respondents reporting a formal postoperative care policy, 48% and 30% admitted patients to a monitored ward bed and surgical intensive care unit, respectively. Of the 74% of respondents unaware of an institutional policy, Anesthesia and Surgery worked together to dictate postoperative disposition of patients with known OSA 73% of the time. The degree of OSA was ranked as the most important factor (58%) influencing postoperative disposition. Ten percent of respondents reported a major perioperative complication attributable to OSA in the past year. CONCLUSION: This survey study elucidates the heterogeneity of preoperative screening for and postoperative care of veterans with OSA. Future investigators may use these data to formalize institutional policies with regard to patients with OSA, with potentially significant impacts on patient care and usage of financial resources.

Keratoacanthoma-type squamous cell carcinoma developing in a skin graft donor site after tumor extirpation at a distant site.

The development of squamous cell carcinoma in split-thickness skin graft donor sites is rare in the reported literature. We report a case of keratoacanthoma-type squamous cell carcinoma developing in a split-thickness skin graft donor site 6 weeks after orbital exenteration for squamous cell carcinoma. We review the literature and discuss possible causes.

Otolaryngologic management of delayed pharyngoesophageal perforation following anterior cervical spine surgery.

Delayed pharyngoesophageal perforation is a rare complication following anterior cervical spine surgery. Patients usually present weeks to years after surgery with vague symptoms, such as dysphagia and neck pain. We report five cases of delayed pharyngoesophageal perforation following anterior cervical spine surgery with hardware fixation. Successful surgical management of these patients required removal of hardware and closure of the defect supported with a vascularized flap.
