RESUMO
Fish bone foreign bodies (FFBs) are relatively common but can present diagnostic challenges. Herein, we report a case of a 43-year-old female who initially presented to the Emergency Department with fever and throat discomfort after a choking incident, which led to a misdiagnosis of a viral infection after negative chest X-ray findings. Persistent symptoms, including new-onset vocal cord paralysis, prompted further investigation and an otolaryngology - head and neck surgery referral one month later. During the otolaryngology visit eight months after the initial incident, laryngoscopy revealed left true vocal cord paralysis and a subsequent CT scan revealed a 2.3 cm fishbone in the esophagus. Surgical removal involved flexible esophagoscopy and open neck exploration with careful dissection to avoid vascular injury. This case highlights the limitations of initial diagnostic methods, such as X-rays, and the necessity for heightened clinical vigilance and advanced imaging modalities like CT scans for persistent or evolving symptoms, particularly vocal cord paralysis. This case also supports multidisciplinary surgical management in cases of suspected esophageal FFBs involving the internal jugular vein and common carotid artery to prevent serious complications.

RESUMO
OBJECTIVE: To compare improvement in patient-reported outcomes (PROM) in persons undergoing endoscopic and open surgical management of Zenker diverticula (ZD). METHODOLOGY: Prospective, multicenter cohort study of all individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative who underwent surgery for ZD. Patient survey, radiography reports, and the 10-item Eating Assessment Tool (EAT-10) pre- and post-procedure were abstracted from a REDCap database, which summarized means, medians, percentages, and frequencies of. Outcome based on operative intervention (endoscopic vs. open) was compared using t-test, Wilcoxon rank sum test or chi-square test, as appropriate. RESULTS: One hundred and forty-seven persons were prospectively followed. The mean age (SD) of the cohort was 68.7 (11.0). Overall, 66% of patients reported 100% improvement in EAT-10; 81% of patients had greater than 75% improvement; and 88% had greater than 50% improvement. Endoscopic was used for n = 109 patients, and open surgical intervention was used for n = 38. The median [interquartile range, IQR] EAT-10 percent improvement for endoscopic treatment was 93.3% [72, 100], and open was 100% [92.3, 100] (p = 0.05). The incidence of intraoperative complications was 3.7% for endoscopic and 7.9% for open surgical management. The median [IQR] in follow-up was 86 and 97.5 days, respectively. CONCLUSION: Both endoscopic and open surgical management of ZD provide significant improvement in patient-reported outcomes. The data suggest that open diverticulectomy may provide a modest advantage in symptomatic improvement compared to endoscopic management. The data suggest that the postoperative complication rate is higher in the open surgical group. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:97-102, 2024.

OBJECTIVE: To assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD). METHODS: Prospective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient-reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t-tests and Wilcoxon Signed Rank test were used to test pre- to post-operative differences in RSI, EAT-10, and VHI-10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report. RESULTS: A total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT-10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT-10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT-10 were statistically significant (p = 0.008, p = 0.03). CONCLUSION: KJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2110-2115, 2023.

OBJECTIVE: Otolaryngology is a surgical field with a high degree of ergonomic risk. The use of head-mounted lighting, loupe magnification, endoscopes, and microscopes is inherent to the field, coupled with repetitive fine motor movements in a constrained anatomic field as well as static, ergonomically unfavorable postures. We seek to review the otolaryngologic literature on ergonomics, including prevalence, severity, and interventions in decreasing work-related musculoskeletal pain. DATA SOURCES: Data were derived from clinical peer-reviewed primary literature as well as information provided by residency programs and presented at national and international meetings. REVIEW METHODS: A comprehensive review was performed by 3 independent reviewers utilizing an electronic database literature search through PubMed, Embase, and Cochrane Library. Search terms included combinations and variations of the following concepts: ergonomics, surgery, otolaryngology, work related musculoskeletal disorders, chronic cervical pain, musculoskeletal, posture, surveys, microsurgery, endoscopic surgery. Strict objective criteria for inclusion were not used due to the inherent heterogeneity in articles and lack of rigorous empirical evidence. CONCLUSIONS: Chronic musculoskeletal pain is prevalent among otolaryngologic surgeons, with many procedures producing high ergonomic risk. Most studies evaluating interventions to decrease ergonomic risks demonstrate promising results, but standardization in methods and outcome reporting is needed. IMPLICATIONS FOR PRACTICE: Literature shows that musculoskeletal pain begins in training, and there is a paucity of information related to ergonomic risk in otolaryngology residency curriculums. Work-related musculoskeletal disorders related to poor workplace ergonomics have the potential to limit career longevity and lead to physician burnout. Interventions to mitigate this risk are effective and tend to be well received by physicians.

OBJECTIVE: To describe demographics and imaging and compare findings and symptoms at presentation in a large cohort of persons with cricopharyngeus muscle dysfunction (CPMD) with and without hypopharyngeal diverticula. METHODOLOGY: Prospective, multicenter cohort study of all individuals enrolled in the Prospective OUtcomes of Cricopharyngeal Hypertonicity (POUCH) Collaborative. Patient survey, comorbidities, radiography, laryngoscopy findings, and patient-reported outcome measures (e.g., Eating Assessment Tool [EAT-10]) data were abstracted from a REDCap database and summarized using means, medians, percentages, and frequencies. Diagnostic categories were compared using analysis of variance. RESULTS: A total of 250 persons were included. The mean age (standard deviation [SD]) of the cohort was 69.0 (11.2). Forty-two percent identified as female. Zenker diverticula (ZD) was diagnosed in 85.2%, 9.2% with CPMD without diverticula, 4.4% with a Killian Jamieson diverticula (KJD), and 1.2% traction-type diverticula. There were no differences between diagnostic categories in regard to age, gender, and duration of symptoms (p = 0.25, 0.19, 0.45). The mean (SD) EAT-10 score for each group was 17.1 (10.1) for ZD, 20.2 (9.3) for CPMD, and 10.3 (9.4) for KJD. Patients with isolated CPMD had significantly greater EAT-10 scores compared to the other diagnostic groups (p = 0.03). CONCLUSION: ZD is the most common, followed by CPMD without diverticula, KJD, and traction-type. Patients with isolated obstructing CPMD may be more symptomatic than persons with ZD or KJD.

PURPOSE: Locoregional relapse in patients with head and neck squamous cell carcinoma (HNSCC) is common, approaching 50% for some subsites despite multimodality therapy. Salvage surgery is the standard of care, but able to achieve durable control in only a minority of patients. While adjuvant radiotherapy or chemo-radiotherapy is offered to select patients, this approach can be prohibitively toxic. Given the activity and tolerability of programmed death-1 inhibitors in metastatic HNSCC, we investigated the safety and efficacy of adjuvant nivolumab after salvage surgical resection. PATIENTS AND METHODS: This was an open-label, multi-institutional phase II clinical trial (NCT03355560). Patients with recurrent, resectable HNSCC were enrolled within 6 weeks of salvage surgery. Six 28-day cycles of adjuvant nivolumab were planned. The primary endpoint was 2-year disease-free survival (DFS) more than 58%, based on an institutional historical control group of 71 patients with recurrent HNSCC who underwent salvage surgery. RESULTS: Between February 2018 and February 2020, 39 patients were enrolled. At a median follow-up of 22.1 months, 2-year DFS was 71.4% [95% confidence interval (CI), 57.8-88.1] and the 2-year overall survival (OS) was 73% (95% CI, 58-91.8). Three of 39 (8%) patients experienced grade 3 treatment-related adverse events and 3 of 39 (8%) discontinued treatment due to side effects. Ten of 39 had locoregional recurrence, while 2 of 10 also had synchronous metastatic disease. There was no difference in DFS between PD ligand-1 (PD-L1)-positive and PD-L1-negative patients. There was a nonsignificant trend toward improved DFS in patients with high tumor mutational burden (P = 0.083). CONCLUSIONS: Adjuvant nivolumab after salvage surgery in locally recurrent HNSCC is well tolerated and showed improved DFS compared with historical controls.

Osteoradionecrosis is a relatively rare but potentially morbid and costly complication of radiation therapy for head and neck cancer. Multidisciplinary diagnosis and treatment are essential. Despite evidence guiding individual aspects of care for osteoradionecrosis, there is a lack of broad consensus on the overall diagnosis and management of this condition. This study comprehensively reviews the literature, with a focus on the past 10 years, to guide evaluation and treatment.

OBJECTIVES: Simulation-based boot camps have emerged as timely vehicles to help novice residents develop the skills needed to manage medical emergencies. Geographically regional boot camps provide opportunities for interaction between residents and faculty from multiple otolaryngology programs. The Society of University Otolaryngologists (SUO) Boot Camp Task Force investigated the concept of regional access to otolaryngology boot camps with the goal of making more regional boot camps available for otolaryngology residents across the United States. STUDY DESIGN: Interviews. METHODS: The SUO Boot Camp Task Force assessed regional access to otolaryngology boot camps with a focus on geographic distribution, curricular content, and finances. Boot camp directors were contacted by email and telephone and interviewed to elicit information on all these areas. RESULTS: Data were available from 10 known regional simulation-based boot camps designed for novice residents. Individual boot camps included from 12 to 30 residents and 10 to 50 faculty members. Curricula included both technical (ie, procedural) and non-technical (eg, communication, leadership) skills for individuals and teams. Content was heavily weighted toward a variety of airway problems and management techniques, although various conditions involving hemorrhage, and airway fires were also addressed. Funding and expense structures had the greatest variability. CONCLUSIONS: Considerable variability was identified among the known regional boot camps in terms of numbers of participants and finances, but fewer differences in curriculum. Geographic opportunity for 9 to 10 new boot camps was identified. The SUO Task Force recommends that a consensus be developed for several individual skill and teamwork scenario objectives to be included in each boot camp. Laryngoscope, 131:737-743, 2021.

The vessel-depleted neck presents a unique and challenging scenario for reconstructive surgery of the head and neck. Prior surgery and radiation often result in significant scarring and damage to the neck vasculature, making identification of suitable recipient vessels for microvascular free tissue transfer exceedingly difficult. Therefore, alternative reconstructive techniques and/or vessel options must be considered to obtain a successful reconstructive outcome for a patient. In this article, we discuss our experience and approach to the management of the vessel-depleted neck, emphasizing the importance of preoperative planning and having multiple backup options prior to surgery. The various preoperative imaging modalities and available options for recipient arteries and veins are presented in detail. Additionally, we discuss modifications of select free flaps to maximize their utility in successful reconstruction. Together with thoughtful preoperative planning, these techniques can help aid the reconstructive surgeon in addressing the complex decisions associated with the vessel-depleted neck.

Preseptal cellulitis is an infection of ocular tissue that is often unilateral and caused by extension of sinonasal disease. In rare instances it can lead to life-threatening necrotizing fasciitis. We present here a unique case of bilateral preseptal cellulitis incited by local conjunctivitis caused by prescription eye drops. The patient was immunosuppressed, which allowed her local inflammation to progress to severe infection and, ultimately, to necrotizing fasciitis. This necessitated serial debridement by ophthalmology and otolaryngology teams and a prolonged course of intravenous antibiotics monitored by an infectious disease team. Despite these interventions, the patient's vision did not return to baseline and she had persistent cosmetic and functional deformity. This case is unique due to the inciting incident of new prescription eye drops, the patient's immunosuppressed state leading to severity of infection, and the severe bilateral disease burden.
RESUMO
PURPOSE OF REVIEW: To review reconstruction techniques following total laryngectomy, partial laryngopharyngectomy, and total laryngopharyngectomy with an emphasis on long-term swallow and speech outcomes. RECENT FINDINGS: Recent literature has shown that the use of fasciocutaneous free flaps in the reconstruction of laryngectomy defects may lead to improved speech and swallow outcomes as compared with regional or free musculocutaneous flaps. Radial forearm and anterolateral thigh are the most often used fasciocutaneous free flaps, with similar speech and swallow outcomes. Primary closure with myofascial flap onlay yields similar speech and swallow results to fasciocutaneous flaps following laryngectomy that spares sufficient pharyngeal mucosa. SUMMARY: Whenever reconstructing a salvage laryngectomy defect or a primary laryngectomy defect with mucosal deficiency, current evidence suggests that a fasciocutaneous free flap used to augment pharyngeal volume both improves fistula rates as well as long-term speech and swallow outcomes. When sufficient pharyngeal mucosa is present, myofascial onlay can be considered as well.

INTRODUCTION: In order to increase junior resident physician proficiency and improve patient safety, simulation-based procedural training courses, or bootcamps, have been become an emerging educational tool. OBJECTIVES: To compare pre- and post-course confidence levels and to assess station efficacy after completion of our single day bootcamp. METHODS: We developed the University of California (UC) Davis otolaryngology bootcamp, a single day course including six cadaveric task trainer stations and four simulations. The six task trainer stations included (1) Epistaxis, (2) Cricothyrotomy/tracheostomy, (3) Peritonsillar abscess/auricular hematoma, (4) Nasal bone reduction/zygoma reduction/lateral canthotomy/canalicular trauma and probing, (5) Local nerve blocks, and (6) Soft tissue reconstruction. The simulations comprised of airway fire during tracheostomy, pediatric respiratory code during airway evaluation, dislodged pediatric tracheostomy tube in the ICU, and angioedema in the emergency department with inability to intubate or ventilate. Junior residents from multiple locoregional institutions were recruited to participate. Pre- and post-course Likert surveys assessing participant confidence and station efficacy were collected and analyzed. RESULTS: There was a statistically significant increase in resident confidence levels for all task trainer stations. All stations had a station efficacy Likert score average of 4 "very effective" or 5 "most effective." CONCLUSION: A multi-institutional, locoregional, simulation-based bootcamp can be a valuable adjunct to junior resident training. It can promote camaraderie, pool limited resources, and may be cost-effective.

BACKGROUND: The diagnosis and management of oral cavity cancer has been well described in developed countries, however, in regions with fewer medical resources, alternative methods may need to be used. We outline an approach to evaluation and treatment of oral cavity cancer in low-resource areas. METHODS: Reviews of the Cochrane and Pubmed databases were performed and literature compiled. Expert opinions from the American and African Head and Neck Societies were also provided. RESULTS: Treatment guidelines for managing oral cavity cancer in low-resource regions are outlined and the level of supporting evidence is defined. DISCUSSION: Successful treatment typically involves the use of upfront surgical resection of the primary lesion and any involved or at-risk cervical lymph node basins, with adjuvant therapy based on the final pathology findings. In situations where services such as adjuvant therapy and/or appropriate reconstruction are not available, alternative approaches to treatment may be needed.

PURPOSE OF REVIEW: Surgical mission trips in head and neck surgery are common. There are an increasing number of surgical groups performing complex reconstructions in low and middle-income countries (LMIC). Consideration of reconstructive options that are location and patient specific are critical for optimum patient care and local physician education. RECENT FINDINGS: The pectoralis muscle regional flap is a versatile and reliable option and has been shown to reconstruct defects in nearly every head and neck subsite. Additional regional flap options described are the supraclavicular island flap and submental island flap. There are 15 published case series describing experience with performing microvascular reconstructions in LMIC. The average success rate was 87.1%. Both loupe and microscope magnification are used. SUMMARY: Complex reconstructions are successfully being performed in LMIC. Although microvascular reconstruction is being utilized by some groups, local and patient-specific factors should be carefully considered, as many regional and local flap options available provide the same reconstruction benefit while minimizing operating room time, resources, and postoperative care needs.

Management of head and neck cancer in the elderly patient is particularly challenging given the high morbidity associated with treatment. Surgery, radiotherapy, and chemotherapy have all been demonstrated as effective in older patients; however, older patients are more susceptible to treatment-induced toxicity, which can limit the survival benefits of certain interventions. This susceptibility is better associated with the presence of multiple comorbidities and decreasing functional status than with age alone. Screening tools allow for risk stratification, treatment deintensification, and even treatment avoidance in patients who are deemed at high-risk of being harmed by standard therapy.

Importance: Three-dimensional (3D) printing is an emerging tool in the creation of anatomical models for simulation and preoperative planning. Its use in sinus and skull base surgery has been limited because of difficulty in replicating the details of sinus anatomy. Objective: To describe the development of 3D-printed sinus and skull base models for use in endoscopic skull base surgery. Design, Setting, and Participants: In this single-center study performed from April 1, 2017, through June 1, 2017, a total of 7 otolaryngology residents and 2 attending physicians at a tertiary academic center were recruited to evaluate the procedural anatomical accuracy and haptic feedback of the printed model. Interventions: A 3D model of sinus and skull base anatomy with high-resolution, 3D printed material (VeroWhite) was printed using a 3D printer. Anatomical accuracy was assessed by comparing a computed tomogram of the original patient with that of the 3D model across set anatomical landmarks (eg, depth of cribriform plate). Image-guided navigation was also used to evaluate accuracy of 13 surgical landmarks. Likert scale questionnaires (1 indicating strongly disagree; 2, disagree; 3, neutral; 4, agree; and 5, strongly agree) were administered to 9 study participants who each performed sinus and skull base dissections on the 3D-printed model to evaluate anatomical accuracy and haptic feedback. Main Outcomes and Measures: Main outcomes of the study include objective anatomical accuracy through imaging and navigation and haptic evaluation by the study participants. Results: Seven otolaryngology residents (3 postgraduate year [PGY]-5 residents, 2 PGY-4 residents, 1 PGY-3 resident, and 1 PGY-2 resident) and 2 attending physicians evaluated the haptic feedback of the 3D model. Computed tomographic comparison demonstrated a less than 5% difference between patient and 3D model measurements. Image-guided navigation confirmed accuracy of 13 landmarks to within 1 mm. Likert scores were a mean (SD) of 4.00 (0.71) for overall procedural anatomical accuracy and 4.67 (0.5) for haptic feedback. Conclusions and Relevance: This study shows that high-resolution, 3D-printed sinus and skull base models can be generated with anatomical and haptic accuracy. This technology has the potential to be useful in surgical training and preoperative planning and as a supplemental or alternative simulation or training platform to cadaveric dissection.

PURPOSE OF REVIEW: To review the use of three-dimensional (3D) printing in facial plastic and reconstructive surgery, with a focus on current uses in surgical training, surgical planning, clinical outcomes, and biomedical research. To evaluate the limitations and future implications of 3D printing in facial plastic and reconstructive surgery. RECENT FINDINGS: Studies reviewed demonstrated 3D printing applications in surgical planning including accurate anatomic biomodels, surgical cutting guides in reconstruction, and patient-specific implants fabrication. 3D printing technology also offers access to well tolerated, reproducible, and high-fidelity/patient-specific models for surgical training. Emerging research in 3D biomaterial printing have led to the development of biocompatible scaffolds with potential for tissue regeneration in reconstruction cases involving significant tissue absence or loss. Major limitations of utilizing 3D printing technology include time and cost, which may be offset by decreased operating times and collaboration between departments to diffuse in-house printing costs SUMMARY: The current state of the literature shows promising results, but has not yet been validated by large studies or randomized controlled trials. Ultimately, further research and advancements in 3D printing technology should be supported as there is potential to improve resident training, patient care, and surgical outcomes.

Traumatic injury to the temporal bone can lead to significant morbidity or mortality and knowledge of the pertinent anatomy, pathophysiology of injury, and appropriate management strategies is critical for successful recovery and rehabilitation of such injured patients. Most temporal bone fractures are caused by motor vehicle accidents. Temporal bone fractures are best classified as either otic capsule sparing or otic capsule disrupting-type fractures, as such classification correlates well with risk of concomitant functional complications. The most common complications of temporal bone fractures are facial nerve injury, cerebrospinal fluid (CSF) leak, and hearing loss. Assessment of facial nerve function as soon as possible following injury greatly facilitates clinical decision making. Use of prophylactic antibiotics in the setting of CSF leak is controversial; however, following critical analysis and interpretation of the existing classic and contemporary literature, we believe its use is absolutely warranted.
