Cricotracheal separation after gunshot to the neck: report of a survivor with recovery of bilateral vocal fold function.

BACKGROUND: Traumatic tracheal injury via blunt or penetrating mechanism comes with a grave prognosis. Cricotracheal separation is a rare entity among these injuries and even more infrequent by means of penetrating trauma. Resultant airway discontinuity subsequent to these insults causes immense global hypoxia and tends to be uniformly fatal. OBJECTIVE: Our aim was to discuss emergent and surgical management of traumatic airway injury. CASE REPORT: We report the case of a 28-year-old male who sustained a gunshot wound to the neck resulting in laryngeal fracture and cricotracheal separation. We review the initial stabilization of his airway and detail the successive surgical management of his injury in the context of the current available literature, with an emphasis on timely airway stabilization when high suspicion for cricotracheal separation exists based on traumatic mechanism. CONCLUSIONS: Emergent management and stabilization of the airway is critical to survival in the context of trauma involving the neck and airway structures.

Primary Site Surgery in Distantly Metastatic Oropharyngeal Squamous Cell Carcinoma.

OBJECTIVES: Determine if intensive local therapy (i.e., local surgery or radiation) has a survival benefit for patients presenting with distantly metastatic oropharyngeal squamous cell carcinoma (OPSCC). METHODS: Retrospective population-based cohort study of patients in the National Cancer Database presenting with distantly metastatic OPSCC. Overall survival (OS) was compared for patients receiving systemic therapy alone or in combination with local surgery or curative dose radiation, controlling for various clinicodemographic factors. RESULTS: Between 2010 and 2015, 627 patients presented with newly diagnosed, metastatic OPSCC and an initial treatment course including systemic chemotherapy. Multivariable analysis demonstrated that local radiation therapy was independently associated with improved OS (OR 0.64, CI [0.51-0.81]); local surgery was not independently associated with improved OS (OR 0.99, CI [0.65-1.53]). Higher T stages were associated with worse OS (OR 1.69, CI [1.14-2.50] for T3 and OR 1.77, CI [1.22-2.58] for T4 compared to T1). HPV-positive (HPV+) tumors were associated with improved OS compared to HPV- (OR 0.79, CI [0.64-0.97]). Multiagent chemotherapy was associated with improved OS compared to single-agent (OR 0.78, CI [0.62-1.00]). The best survival for the entire cohort and for HPV+ patients was for radiation with systemic therapy and the worst survival for systemic therapy alone. CONCLUSIONS: Curative dose local radiotherapy in addition to systemic therapy is associated with improved OS compared to systemic therapy alone in patients presenting with distantly metastatic OPSCC. There is not a significant survival benefit for local surgery in addition to systemic therapy in this patient population, regardless of HPV status.

High-Risk Cutaneous Squamous Cell Cancer of the Head and Neck: Risk Factors for Recurrence and Impact of Adjuvant Treatment.

OBJECTIVES: The behavior of advanced cutaneous squamous cell carcinoma of the head and neck (HNcSCC) remains poorly understood, with highly variable risk factors and a paucity of data for adjuvant treatment. The objective of our study was to review the oncologic outcomes of patients with high-risk HNcSCC treated with surgery and to identify risk factors for treatment failure. STUDY DESIGN: Retrospective cohort study. METHODS: Retrospective review of patients treated for HNcSCC with definitive surgery involving at least parotidectomy and neck dissection at a tertiary care academic center from 2011 to 2017 was conducted. The primary outcome was disease-free survival (DFS). RESULTS: One-hundred four patients with a median age of 68 years (range = 42-91 years) were reviewed. Twenty-one patients were treated with surgery alone, 45 patients underwent adjuvant radiotherapy (RT), and 38 patients underwent adjuvant chemoradiotherapy (CRT). The 2-year DFS for patients treated with surgery, surgery + RT, and surgery + CRT were 71%, 65%, and 58%, respectively, with no significant difference between the groups (P = .70). On multivariate analyses, tumor size (P = .006) and perineural invasion (PNI, P = .04) independently predicted recurrence. The addition of chemotherapy did not appear to improve DFS, neither for those patients with extranodal extension and/or positive margins (P = .93) nor for the entire cohort (P = .43). CONCLUSIONS: Advanced HNcSCC has a high recurrence rate despite adjuvant treatment. Tumor size >2 cm was a strong independent risk factor for recurrence. Out of the traditional mucosal HNcSCC risk factors, PNI was most strongly associated with worse DFS. There was no observed survival benefit to the addition of chemotherapy. LEVEL OF EVIDENCE: 4.

False-positive reverse transcriptase polymerase chain reaction screening for SARS-CoV-2 in the setting of urgent head and neck surgery and otolaryngologic emergencies during the pandemic: Clinical implications.

BACKGROUND: No reports describe falsepositive reverse transcriptase polymerase chain reaction (RT-PCR) for novel coronavirus in preoperative screening. METHODS: Preoperative patients had one or two nasopharyngeal swabs, depending on low or high risk of viral transmission. Positive tests were repeated. RESULTS: Forty-three of 52 patients required two or more preoperative tests. Four (9.3%) had discrepant results (positive/negative). One of these left the coronavirus disease (COVID) unit against medical advice despite an orbital abscess, with unknown true disease status. The remaining 3 of 42 (7.1%) had negative repeat RT-PCR. Although ultimately considered falsepositives, one was sent to a COVID unit postoperatively and two had urgent surgery delayed. Assuming negative repeat RT-PCR, clear chest imaging, and lack of subsequent symptoms represent the "gold standard," RT-PCR specificity was 0.97. CONCLUSIONS: If false positives are suspected, we recommend computed tomography (CT) of the chest and repeat RT-PCR. Validated serum immunoglobulin testing may ultimately prove useful.

Ethical surgical triage of patients with head and neck cancer during the COVID-19 pandemic.

BACKGROUND: Coronavirus has serially overtaken our metropolitan hospitals. At peak, patients with acute respiratory distress syndrome may outnumber mechanical ventilators. In our Miami Hospital System, COVID-19 cases have multiplied for 4 weeks and elective surgery has been suspended. METHODS: An Otolaryngologic Triage Committee was created to appropriately allocate resources to patients. Hospital ethicists provided support. Our tumor conference screened patients for nonsurgical options. Patients were tested twice for coronavirus before performing urgent contaminated operations. N95 masks and protective equipment were conserved when possible. Patients with low-grade cancers were advised to delay surgery, and other difficult decisions were made. RESULTS: Hundreds of surgeries were canceled. Sixty-five cases screened over 3 weeks are tabulated. Physicians and patients expressed discomfort regarding perceived deviations from standards, but risk of COVID-19 exposure tempered these discussions. CONCLUSIONS: We describe the use of actively managed surgical triage to fairly balance our patient's health with public health concerns.

Controversies in free tissue transfer for head and neck cancer: A review of the literature.

BACKGROUND: Microvascular free tissue transfer provides superior functional outcomes when reconstructing head and neck cancer defects. Careful patient selection and surgical planning is necessary to ensure success, as many preoperative, intraoperative, and postoperative patient and technical factors may affect outcome. AIMS: To provide a concise, yet thorough, review of the current literature regarding free flap patient selection and management for the patient with head and neck. MATERIALS AND METHODS: PubMed and Cochrane databases were queried for publications pertaining to free tissue transfer management and outcomes. RESULTS: Malnutrition and tobacco use are modifiable patient factors that negatively impact surgical outcomes. The use of postoperative antiplatelet medications and perioperative antibiotics for greater than 24 hours have not been shown to improve outcomes, although the use of clindamycin alone has been shown to have a higher risk of flap failure. Liberal blood transfusion should be avoided due to higher risk of wound infection and medical complications. DISCUSSION: There is a wide range of beliefs regarding proper management of patients undergoing free tissue transfer. While there is some data to support these practices, much of the data is conflicting and common practices are often continued out of habit or dogma. CONCLUSION: Free flap reconstruction remains a highly successful surgery overall despite as many different approaches to patient care as there are free flap surgeons. Close patient monitoring remains a cornerstone of surgical success.

An Unusual Hybrid Salivary Gland Tumor: Molecular Analysis Informs the Potential Pathogenesis of This Rare Neoplasm.

BACKGROUND: The presence of two or more tumor entities growing in adjacent locations within the salivary gland is very rare, and pathologic studies on such lesions are limited, particularly those with molecular information. Since the clinical history and imaging studies are usually nonspecific, accurate diagnosis and clinical management largely depend on a thorough histological examination. METHODS AND RESULTS: We describe a 71-year-old man with an unusual case of hybrid salivary gland tumor composed of mucoepidermoid carcinoma and basal cell adenoma. Molecular analysis revealed differing driver genetic alterations in each component. CONCLUSIONS: Hybrid salivary gland tumors are rare, and their pathogenesis is controversial. The combination of mucoepidermoid carcinoma and basal cell adenoma has not been previously described. While malignant transformation of adenoma to carcinoma seems plausible, gene sequencing was more suggestive of their independent derivation. Key to appropriate surgical management is identifying the more aggressive component, ideally at the time of intraoperative consultation.

Meta-analysis comparing outcomes of different transoral surgical modalities in management of oropharyngeal carcinoma.

BACKGROUND: Optimal transoral surgical modality for oropharyneal carcinoma is currently unclear. Transoral laser surgery (TLS), transoral robotic surgery (TORS), and conventional direct transoral (DT) oropharyngectomy are the main current transoral surgical modalities for oropharyngeal carcinoma. METHODS: MEDLINE was systematically searched through PubMed. Reference lists were reviewed. Random-effects models were used to combine studies within each group. Tests for heterogeneity were used to explore difference in effect size between groups in subgroup analysis. RESULTS: Nine studies (404 patients) in TORS arm, five studies (498 patients) in TLS arm, and three studies (335 patients) in DT arm were included. Early T classification (T1-T2) for TORS and DT were higher compared to TLS group (P < .001). There was no significant difference between groups in the rate of invaded margin, post-operative oropharyngeal bleeding, temporary tracheotomy, and gastrostomy dependence. CONCLUSION: The available data do not yet provide clear evidence of superiority of any one modality.

Laser-welded endoscopic endoluminal repair of iatrogenic esophageal perforation: an animal model.

OBJECTIVE: To test the feasibility of laser tissue welding (LTW) in creating an endoscopic transluminal repair of esophageal perforation. STUDY DESIGN: Animal model. SUBJECTS AND METHODS: A diode laser was used to create an endoluminal rabbit esophageal perforation repair. Burst pressures were compared with open incision, external suture, and external laser-augmented suture closure. Comparisons were performed five times and analyzed with Kruskal-Wallis analysis of variance and a post hoc Dunn method. RESULTS: The burst threshold of the endoluminal weld (54.78 +/- 5.84 mm Hg) was significantly higher than that of the open incision (6.5 +/- 1.94 mm Hg) and not significantly different than that of the external suture (37.18 +/- 1.97 mm Hg) or the laser-augmented suture group (71.60 +/- 7.58 mm Hg). CONCLUSION: Laser welding is a feasible method of creating endoluminal repairs with burst strengths comparable with external suture repair, which may allow a subset of patients to avoid traditional open approaches. This is the first reported animal model of LTW for endoscopic closure of iatrogenic esophageal perforation.

Comparison of endoscopic and microscopic removal of pituitary adenomas: single-surgeon experience and the learning curve.

OBJECT: The endoscopic endonasal approach for resection of pituitary lesions is an effective surgical option for tumors of the sella turcica. In this study the authors compared outcomes after either purely endoscopic resection or traditional microscope-aided resection. They also attempted to determine the learning curve associated with a surgical team converting to endoscopic techniques. METHODS: Retrospective data were collected on patients who were surgically treated for a pituitary lesion at the Hospital of the University of Pennsylvania between July 2003 and May 2008. Age, sex, race, presenting symptoms, length of hospital stay, surgical approach, duration of surgery, tumor pathological features, gross-total resection (GTR) of tumor, recurrence of the lesion, and intraoperative and postoperative complications were noted. All procedures were performed by the same senior neurosurgeon, who was initially unfamiliar with the endoscopic endonasal approach. RESULTS: A total of 25 patients underwent microscopic resection and 25 patients underwent endoscopic resection performed by a single skull base team consisting of the same senior neurosurgeon and otorhinolaryngologist (M.S.G. and B.W.O.). In the microscopically treated cohort, there were 8 intra- or postoperative complications, 6 intraoperative CSF leaks, 17 (77%) of 22 patients had GTR on postoperative imaging, 5 patients underwent >or= 2 operations, and 10 (59%) of 17 patients reported total symptom resolution at follow-up. The endoscopically treated group had 7 intraor postoperative complications and 7 intraoperative CSF leaks. Of the patients who had pre- and postoperative imaging studies, 14 (66%) of 21 endoscopically treated patients had GTR; 4 patients had >or= 2 operations, and 10 (66%) of 15 patients reported complete symptom resolution at follow-up. The first 9 patients who were treated endoscopically had a mean surgical time of 3.42 hours and a mean hospital stay of 4.67 days. The next 8 patients treated had a mean surgical time of 3.11 hours and a mean hospital stay of 3.13 days. The final 8 patients treated endoscopically had a mean surgical time of 2.22 hours and a mean hospital stay of 3.88 days. The difference in length of operation between the first 9 and the last 8 patients treated endoscopically was significantly different. There was a trend toward decreased CSF leaks and other complications from the first 2 groups compared with the third group. CONCLUSIONS: In this subset of patients, the use of endoscopic endonasal resection results in a similar complication and symptom resolution rate compared with traditional techniques. The authors postulate that the learning curve for endoscopic resection can be

Value within otolaryngology: Assessment of the cost-utility analysis literature.

OBJECTIVE: To assess the characteristics and quality of cost utility analyses (CUA) related to otolaryngology within the CEA registry and to summarize their collective results. METHODS: All cost-utility analyses published between 1976 and 2011 contained in the Cost-Effectiveness Analysis Registry (CEA Registry) were evaluated. Topics that fall within the care of an otolaryngologist were included in the review regardless of the presence of an otolaryngologist author. Potential associations between various study characteristics and CEA registry quality scores were evaluated using the Pearson product moment correlation coefficient. RESULTS: Sixty-one of 2913 (2.1%) total CUA publications screened were related to otolaryngology. Eighteen of 61 (29.5%) publications included an otolaryngologist as an author. Fourteen studies agreed on the cost effectiveness of at least unilateral cochlear implantation and six of seven (85.7%) studies demonstrated the cost effectiveness of continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA). Forty-six percent (28 of 61) of all manuscripts were published between 2008 and 2011. A more recent publication year was associated with a higher CEA registry quality score while the presence of an otolaryngologist author and journal impact factor had no significant correlation with the quality of the CUA. CONCLUSION: Based on current evidence in the CEA registry, unilateral cochlear implantation for hearing loss and CPAP for OSA are both cost-effective therapeutic interventions. Although CUAs in otolaryngology have increased in quantity and improved in quality in more recent years, there is a relative lack of CUAs in otolaryngology in comparison to other subspecialties.

Surgical Techniques for Zenker's Diverticulum: A Comparative Analysis.

OBJECTIVE: To compare the different modalities for treatment of Zenker's diverticulum and the associated clinical outcomes. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care hospital. SUBJECTS AND METHODS: Between 1995 and 2011, 164 patients underwent surgery for Zenker's diverticulum (stapler, n = 69; laser, n = 68; open, n = 27). Patient sociodemographics, medical comorbidities, pre- and postoperative subjective dysphagia and regurgitation score, complications, length of stay, time to oral intake, and recurrence were reviewed for each surgical modality. RESULTS: No statistically significant difference in diverticulum prevalence was associated with age, gender, or treatment group. Mean length of hospital stay was not significantly different between the 3 groups (P = .14). A significant difference in time to oral intake was observed in the laser group compared with the other 2 groups (P = .012). No significant difference in recurrence (P = .21) or complication (P = .12) rates was identified between the 3 groups. Although all 3 groups demonstrated a significant decrease between preoperative and postoperative dysphagia and regurgitation scores, the degree of improvement was not significant when the 3 groups were compared. CONCLUSION: There is no single "best" approach to Zenker's diverticulum. The open, laser, and stapler methods are equally effective and have similar complication rates.

Diagnosis and treatment of pediatric vallecular cysts and pseudocysts.

OBJECTIVE: To review the experience at a children's hospital diagnosing and treating vallecular cysts. SECONDARY OBJECTIVES: To determine if cyst type, operative mode, or ages are risk factor(s) for recurrence. METHODS: Chart review of eleven children with vallecular cysts and pseudocysts from 1997 to 2009. RESULTS: The most common presenting symptoms were stridor (8/12, 67%), respiratory distress (7/12, 58%), and feeding difficulties (4/12, 33%). Symptoms of gastroesophageal reflux disease were present in 67% of patients and 17% carried a concurrent diagnosis of laryngomalacia. Eleven of twelve patients required operative intervention, the majority of which were transoral endoscopic procedures. Three patients (3/11, 27%) had recurrences. Two of these patients required only a second procedure, but one patient required multiple procedures. Fifty percent (2/4) of the patients 2 years or older experienced a recurrence, whereas only 14% (1/7) of the patients less than 2 years old had a recurrence, a difference which was not statistically significant (p=0.49). Pseudocysts tended to recur more frequently than vallecular cysts. (p=0.13). Surgical approach (marsupialization versus total excision) did not affect recurrence rate. One patient with a small, asymptomatic cyst was observed and continues to be symptom-free. There were no surgical complications. CONCLUSIONS: Vallecular cysts and pseudocysts are rare congenital lesions of the upper aerodigestive tract. Vallecular pseudocysts tended to recur more than vallecular cysts in our series. Surgery is the treatment of choice for symptomatic patients; smaller cysts may be followed closely.

Warthin tumor presenting as a fungal abscess in an immunocompetent host: case report and review of the literature.

BACKGROUND: Fungal abscesses of the parotid gland are rare, and cases arising within parotid neoplasms have not been described previously. This report conveys our experience managing such an entity, which is further distinguished by its occurrence in an immunocompetent host. METHODS AND RESULTS: A 59-year-old man experienced multiple recurrences of a parotid fungal abscess requiring repeated drainage procedures. Definitive excision ultimately demonstrated Candida glabrata infecting a Warthin tumor. CONCLUSIONS: This case is the first report of a parotid neoplasm presenting as a fungal abscess. It contributes to the scant literature on fungal abscesses of the parotid, which previously has only been described in debilitated hosts and without an associated neoplasm. The case also expands the spectrum of disease associated with C. glabrata. Warthin tumor may be an occult etiology for a parotid fungal abscess, and definitive diagnosis and therapy may require parotidectomy.
