ABSTRACT

BACKGROUND: The concept of reserve flow perfusion for free flap reconstruction has been demonstrated in various applications in the literature. As it relates to the anterolateral thigh (ALT) free flap, the reserve flow principle has been primarily described to either augment or "supercharge" a large ALT to optimize skin perforator supply or lengthen the vascular pedicle. METHODS: We report a case of a 77-year old male with chronic renal failure who had extensive atherosclerosis of the proximal descending lateral circumflex femoral artery (LCFA) where arterial anastomosis was unable to be performed. RESULTS: We were able to circumvent this limitation by establishing reserve flow perfusion solely through the distal end of the descending LCFA. We describe our technique within the context of current literature on the topic of reverse flow perfusion in free flap reconstruction. CONCLUSION: This report uniquely describes applying the distally based, reverse arterial flow principle in an ALT flap to circumvent an atherosclerotic proximal pedicle.

ABSTRACT

Introduction Human papillomavirus-related (HPV + ) oropharyngeal squamous cell carcinoma (OPSCC) is increasing in incidence and presents diagnostic challenges given its unique clinical presentation. Objective The purpose of the present study is to characterize the impact of the unique clinical presentation of HPV-related OPSCC on delays in diagnosis. Methods Retrospective review of presenting symptoms and clinical characteristics of 284 patients with OPSCC treated from 2002-2014. Delay in diagnosis was defined as the presence of any of the following: multiple non-diagnostic fine needle aspirate (FNA) biopsies; two or more courses of antibiotic therapy; surgery with incorrect preoperative diagnosis; evaluation by an otolaryngologist without further workup; or surgery without definitive postoperative diagnosis. Results p16+ tumors demonstrated a distinct clinical presentation that more commonly involved a neck mass (85.1% versus 57.3% of p16-; p < 0.001) and less frequently included odynophagia (24.6% versus 51.7% of p16-; p < 0.001). Patients who experienced diagnostic delay were more likely to have p16+ tumors (77.7% delayed versus 62.8% not delayed; p = 0.006). p16+ primary tumors were more likely to be undetectable by physical examination of the head and neck including flexible laryngoscopy (19.0% versus 6.7% of p16-; p = 0.007) and more frequently associated with nondiagnostic FNA biopsies of a cervical nodal mass (11.8% versus 3.4% of p16-, p = 0.03). Conclusions Compared with non-HPV related OPSCC, the unique clinical presentation and characteristics of HPV+ OPSCC are associated with an increased incidence of diagnostic delay. Targeted education of appropriate care providers may improve time to diagnosis and treatment.

ABSTRACT

BACKGROUND: Oncocytic carcinoma (OCA) was recently reclassified as a distinct differentiated thyroid carcinoma (DTC). Given its rarity, OCA studies are limited. This study describes the characteristics of OCA in a 20-year cohort. METHODS: Retrospective analysis of patients with OCA at a single tertiary care hospital from 2000 to 2021. RESULTS: Fifty-one OCA patients (22M:29F) were identified. The mean age at diagnosis was 60.3 years; 90% presented as palpable mass; 24% had a family history of thyroid cancer. None had vocal fold paresis. On ultrasound, most tumors were solid and hypoechoic. FNA (n = 14) showed Bethesda-4 lesions in 93%. All were treated surgically. Histologically, 63% demonstrated angioinvasion, 35% had lymphovascular invasion, and 15% had extrathyroidal extension. Radioactive iodine was used as adjunct therapy in 77%. CONCLUSION: OCA has distinct features that distinguish it from other DTCs, and additional focused studies will help clarify the aggressive nature, treatment options, and prognosis of the disease.

ABSTRACT

INTRODUCTION: The standard complete evaluation of patients with head and neck squamous cell carcinoma (HNSCC) has included a staging exam under anesthesia (EUA) since the 1970s. The EUA for all sites of HNSCC has historically consisted of panendoscopy for the purpose of diagnostic biopsy, accurate staging of primary disease, and identification of second primary tumors. However, due to the accessibility of the oral cavity, the sole purpose of EUA for tumors of this site is to identify second primary tumors. Since the EUA became the gold standard for evaluation of HNSCC, there have been significant advancements in less invasive technologies such as CT, PET-CT, MRI, and fiberoptic examination. In this study, we sought to determine the value to patient care and cost-effectiveness of EUA in patients with oral cavity squamous cell carcinoma (OCSCC). METHODS: A retrospective chart review identified 77 patients who underwent EUA for OCSCC. RESULTS: The most common subsites were the oral tongue and floor of mouth (59.7% and 24.7% respectively). All underwent direct laryngoscopy, 94.8% underwent esophagoscopy, and 20.8% underwent flexible transnasal examination in clinic prior to EUA. For 90.9% of patients, the EUA did not change initial T-staging based on clinical examination and imaging. The remaining 9.1% of patients were upstaged after EUA, however this change did not impact the treatment plan. Second primary tumors were identified in 3.9% of patients, all were found in either the oral cavity or oropharynx, and were also identified with clinical examination or imaging. Analysis of patient charges determined an average cost of $8,022.93 per patient under the current paradigm involving EUA, however with a new algorithm eliminating mandatory EUA average cost decreases to $1,448.44. CONCLUSION: Formal EUA has historically been the gold standard for all HNSCC tumors. However, when performed for cases of oral cavity carcinoma, it is safe and cost effective to limit its use to select clinical scenarios.

ABSTRACT

OBJECTIVE: Recent years have seen increase in individuals pursuing postgraduate fellowships in head and neck (HN) surgery. This has presented concerns about insufficient jobs where graduates can apply their scope of specialized training. METHODS: Data was collected in two manners- a survey and a manual online search of American Head and Neck Society (AHNS) fellowship graduates. A 25-question survey was sent in 2021 to approximately 400 HN fellows who graduated between 2010 and 2020. The AHNS list of graduates from the same years were searched online to collect information including gender, graduation year, fellowship training, and current job practice. RESULTS: Of the 78 survey responses, 64.1 % were male and 34.6 % female. 96.2 % reported ablative, 84.6 % microvascular, and 82.1 % TORS training. Mean number of interviews was 4 with most interviewing during the 3rd quarter (January to March). Majority reported being in academic and university-based practices (79.6 %). Online search was done on 393 graduates. Since 2010 the number of graduates almost doubled. There was a statistically significant increase in females by year (p = 0.022). There was a significant decrease (p = 0.022) in graduates with additional fellowship training from that of their AHNS fellowship. There was also a statistically significant increase in graduates being in academic practices (p = 0.022). CONCLUSION: Despite growing numbers, there appears to be more graduates entering an academic practice, although the definition of an academic HN practice may be evolving. These results provide guidance on how to approach the job search in a select market. LEVEL OF EVIDENCE: II.

ABSTRACT

BACKGROUND: Postparotidectomy sialocele is a frustrating challenge. Published rates of postparotidectomy fluid collections range from 6% to 39%. We report our experience of 398 parotidectomies performed over a 6-year period. METHODS: A retrospective chart review of parotidectomies performed over a 6-year period was completed. Drain placement, smoking status, tumor size, and postoperative utilization of scopolamine were analyzed. Binary logistical regression and odds ratio calculations were performed. RESULTS: Postparotidectomy sialocele occurred in 25% of patients. Neither suction drain placement nor usage of immediate postoperative scopolamine (in a 22-patient subset) prevented sialocele formation. Smoking status also did not correlate. Increasing resection size was linearly correlated with the risk of sialocele. CONCLUSION: Drain placement and smoking status do not correlate with sialocele prevention after parotidectomy. Sialocele formation directly correlates with the resection size. These data may guide preoperative counseling; however, additional work is necessary to identify effective prevention mechanisms for postparotidectomy sialocele.

ABSTRACT

OBJECTIVE: To determine the diagnostic efficacy and clinical value of preoperative computed tomography (CT) and magnetic resonance imaging (MRI) among patients with suspected temporal bone encephaloceles (TBE). STUDY DESIGN: Retrospective chart review from 2006 to 2018. SETTING: Tertiary referral center. SUBJECTS AND METHODS: The subjects underwent surgery for a clinically suspected TBE or cerebrospinal fluid (CSF) leak. Preoperative imaging test characteristics of CT and MRI, including sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), were calculated for TBE scans and compared with intraoperative findings. RESULTS: Fifty-seven subjects with otorrhea, middle ear effusion, hearing loss, and/or meningitis with suspected TBE or CSF leak were identified. All had preoperative CT scans, and 61% (35/57) had preoperative MRI scans. Intraoperatively, 37 of 57 patients (65%) were found to have a TBE. CT scans (17% sensitivity, 100% specificity, 100% PPV, 46% NPV) were less sensitive than MRI (58% sensitivity, 100% specificity, 100% PPV, 24% NPV) for detecting TBEs. Furthermore, the time from initial scan to operative repair was significantly longer in those who had a CT followed by MRI scan compared with CT alone or a fused CT-MRI scan (mean = 68 vs 15 days, respectively; P = .004). CONCLUSION: CT and MRI provide complementary information that may aid surgical planning. However, imaging cannot always rule out TBE. In cases with high clinical suspicion, surgical confirmation is often required for definitive diagnosis and treatment. The cost of an additional preoperative study should be considered before its use.

ABSTRACT

OBJECTIVE: We describe our experience using the extracorporeal video microscope, the "exoscope" for repair of a temporal bone encephalocele. METHOD: The patient is a 69-year-old male with a right temporal lobe encephalocele herniating through a tegmen defect. He underwent definitive tegmen defect repair and bipolar cauterization of the encephalocele. The authors elected for a combined transmastoid and transtemporal approach in order to isolate the tegmen defect and provide watertight repair. The Synaptive robotic BrightMatter (Toronto, ON) drive video exoscope monitor system was used for the entirety of the case including both the transmastoid approach and transtemporal craniotomy. RESULTS: No intraoperative complications were encountered during either the transmastoid (mastoidectomy) or transtemporal craniotomy. The authors were able to complete the entire case without abandonment of the exoscope in favor of the traditional binocular microscope. Advantages of this technology in clinical practice includes high-resolution three-dimensional visualization, increased degrees of freedom for exoscope adjustment, and reduced surgeon fatigue in a fixed, unnatural posture. Limitations include decreased depth perception and increased operative time. CONCLUSION: The exoscope system is a safe and effective alternative or adjunct to the existing binocular operating microscope for lateral skull based procedures. The exoscope provides the surgeon with a comfortable, high-resolution visualization without compromising surgical exposure and patient safety.SDC video link: http://links.lww.com/MAO/A837.

ABSTRACT

OBJECTIVE: We describe our experience using the extracorporeal video microscope, the "exoscope" for various applications within the field of lateral skull base surgery. STUDY DESIGN: A retrospective case series was performed investigating patient demographics, indications for surgery, procedure type, operative time, approach to the skull base, complications, adequacy of visualization, and surgeon comfortability. PATIENTS: Six cases were performed with a three dimensional surgical exoscope, obviating the use of a traditional binocular microscope. SETTING: Academic, tertiary referral center. MAIN OUTCOME MEASURES: Type of surgical approach, operative time, patient demographics, surgical complications, and surgeon comfortability. RESULTS: The following procedures were performed; four vestibular schwannoma resections via suboccipital craniotomy and two combined transmastoid and transtemporal approaches for temporal lobe encephalocele repairs. The average operative time was 227 and 577 minutes for temporal lobe encephalocele repairs and vestibular schwannoma cases, respectively. No intraoperative complications were encountered during these cases. None of the procedures required abandonment of the exoscope in favor of the microscope during the procedure. Advantages include high-resolution three-dimensional visualization, increased degrees of freedom for exoscope adjustment, and reduced surgeon fatigue in a fixed, unnatural posture. Limitations include decreased depth perception and increased operative time. CONCLUSION: The exoscope system is a safe and effective alternative or adjunct to the existing binocular operating microscope for lateral skull based procedures. The exoscope provides the surgeon with a comfortable, high-resolution visualization without compromising surgical exposure and patient safety. LEVEL OF EVIDENCE: 4.

ABSTRACT

Cancer of the hypopharynx is relatively rare and accounts for roughly 3% of all head and neck cancers. Unfortunately, hypopharyngeal carcinoma has one of the worst prognosis of all head and neck cancers with a reported 5-year overall survival rate of approximately 30-35%. Toxicity related to therapy, and the need for surgical salvage continue to dominate the landscape in this disease. In this article, we set out to discuss a comprehensive overview of the current management principles, recent literature and evidence based therapeutic options surrounding treatment for hypopharyngeal squamous cell carcinoma, with a special focus on the evolution of an organ sparing paradigm.

ABSTRACT

OBJECTIVES/HYPOTHESIS: Patients who present to the emergency department (ED) with various otolaryngologic disorders are frequently referred to an otolaryngologist for follow-up care. Our aim was to further characterize this group as it has not been well described in the literature. STUDY DESIGN: Cross-sectional retrospective study. METHODS: We reviewed the charts of patients seen during an 18-month period in an urban public hospital trauma center adult ED and referred to an otolaryngology clinic for follow-up care. RESULTS: Seven hundred thirty-eight patients were seen and referred; the most common diagnoses made by ED providers were peripheral vertigo (12%), otitis externa (8%), and nasal fractures (8%). Nine percent of patients were evaluated during their ED visit by an otolaryngology provider. Three hundred seventy-two (50%) patients returned for their otolaryngology clinic visit; facial trauma patients were least likely to return. The most common diagnoses made by otolaryngology providers were otitis externa (12%), peripheral vertigo (12%), and nasal fractures (7%). There was 50% concordance between patients' diagnoses made by ED and otolaryngology providers. The most common differences were otitis media versus otitis externa (10%) and acute pharyngitis versus laryngopharyngeal reflux (8%). During 37% of follow-up visits, an in-office procedure was performed, most commonly flexible fiberoptic laryngoscopy, cerumen removal, and nasal endoscopy. CONCLUSIONS: Our analysis reports comprehensive characteristics of this referral group, identifying potential areas for improvement in patient management, resident education and efficiency. Otolaryngologists covering EDs should be familiar with this population in terms of types of cases that may affect their practices. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:1062-1067, 2018.

ABSTRACT

BACKGROUND: Traditional methods of staging chronic rhinosinusitis (CRS) through imaging do not differentiate between degrees of partial mucosal sinus inflammation, thus limiting their utility as imaging biomarkers. We hypothesized that software-aided, quantitative measurement of sinus inflammation would generate a metric of disease burden that would correlate with clinical parameters in patients with suspected sinus disease. METHODS: Adults with rhinologic complaints undergoing computed tomography imaging were recruited at an urban, academic, tertiary care center (n = 45 with Lund-Mackay [LM] scores ≥4). Three-dimensional (3D) volumetric image analysis was performed using a semiautomated method to obtain a "Chicago-modified Lund-Mackay" (Chicago MLM) score, which provides a continuous scale to quantify extent of opacification. Linear regression was used to test the association of the Chicago MLM score with concurrent symptoms (Total Nasal Symptom Score [TNSS]) and disease-specific quality of life, based on the Sinonasal Outcome Test-22 (SNOT-22). RESULTS: Chicago MLM scores were significantly associated with both symptoms (p = 0.037) and disease-specific quality of life (p = 0.007). Inflammation in the ethmoid and sphenoid sinuses appeared to influence these associations. These findings were even more robust when analysis was limited to patients with more severe disease (LM >6). CONCLUSION: The quantitative measurement of sinus inflammation by computer-aided 3D analysis correlates modestly with both symptoms and disease-specific quality of life. Posterior sinuses appear to have the greatest impact on these findings, potentially providing an anatomic target for clinicians to base therapy. The Chicago MLM score is a promising imaging biomarker for clinical and research use.
