Oral and Pharyngeal Dysphagia in Adults.

Patients with oral and pharyngeal dysphagia have difficulty forming a cohesive bolus and/or transferring food from the mouth into the pharynx and esophagus to initiate the involuntary swallowing process. This may be accompanied by nasopharyngeal regurgitation, aspiration, and a sensation of residual food remaining in the pharynx. Abnormalities affecting the upper esophageal sphincter, pharynx, larynx, or tongue, in isolation or combination, result in oropharyngeal dysphagia affecting either or both transit and airway protection. These issues can be addressed with a combination of management of the underlying systemic disease, with surgical intervention or with swallow therapy.

The use of Montgomery salivary bypass tubes and pharyngocutaneous fistula following salvage laryngectomy.

Objectives: Pharyngocutaneous fistula (PCF) is the most common complication to follow total laryngectomy (TL) and is associated with increases in length of hospital stay and with a need for revision surgery or readmission, as well as with delays in return to oral diet. Patients who require salvage TL (STL) or primary (chemo)radiation therapy are at higher risk for developing PCF. Due to the quality-of-life burden of PCF on patients, limiting this occurrence is crucial. Methods: We conducted a retrospective cohort study of patients undergoing STL with placement of Montgomery salivary bypass tube (MSBT)™ for at least 2 weeks duration between 2013 and 2017 at a single institution. Our patients all underwent free flap reconstruction. Our primary outcome of interest was development of PCF. Secondary outcomes included demographics, previous treatment, base of tongue (BOT) involvement, extent of defect, concurrent neck dissection (ND), and margin status. Univariate χ 2 analysis was used to evaluate factors associated with PCF. Results: Forty-four patients underwent STL with Montgomery tube placement and free flap reconstruction. Eight developed PCF (18.2%). The average age was 61.6 years; 36 patients were male (81.8%), whereas eight patients were female (18.2%). There was no association between PCF and previous chemoradiation versus radiation (15.8% vs. 33.3%, P < 0.30), BOT involvement versus not (11.1 vs. 22.2%, P < 0.38), circumferential versus partial defect (18.8% vs. 17.9%, P < 0.94), ND versus none (10% vs. 25%, P < 0.20), or margin status. Conclusion: PCF complicated 18.2% of STL cases at our institution and was not associated with differences in primary treatment modality, presence of concomitant ND, extent of pharyngeal defect, BOT involvement, or positive frozen or permanent surgical margin.

Established Adult Tracheostomy Tube Exchange: How Often is Enough?

Currently, there is no clinical consensus on how often adults with long-term tracheostomies should have their tubes exchanged. For high-functioning patients who are able to provide diligent tracheostomy care tubes can be exchanged every 6 months. Patients who have a difficult time with tracheostomy care should have them exchanged every 1-3 months.

Implementation of a novel peer review academy by Surgery and the Association of Women Surgeons.

BACKGROUND: A novel Peer Review Academy was developed as a collaborative effort between the Association of Women Surgeons and the journal Surgery to provide formal training in peer review. We aimed to describe the outcomes of this initiative using a mixed methods approach. METHODS: We developed a year-long curriculum with monthly online didactic sessions. Women surgical trainee mentees were paired 1:1 with rotating women surgical faculty mentors for 3 formal peer review opportunities. We analyzed pre-course and post-course surveys to evaluate mentee perceptions of the academy and assessed changes in mentee review quality over time with blinded scoring of unedited reviews. Semi-structured interviews were conducted upon course completion. RESULTS: Ten women surgical faculty mentors and 10 women surgical trainees from across the United States and Canada successfully completed the Peer Review Academy. There were improvements in the mentees' confidence for all domains of peer review evaluated, including overall confidence in peer review, study novelty, study design, analytic approach, and review formatting (all, P ≤ .02). The mean score of peer review quality increased over time (59.2 ± 10.8 vs 76.5 ± 9.4; P = .02). In semi-structured interviews, important elements were emphasized across the Innovation, Implementation Process, and Individuals Domains, including the values of (1) a comprehensive approach to formal peer review education; (2) mentoring relationships between women faculty and resident surgeons; and (3) increasing diversity in the scientific peer review process. CONCLUSION: Our novel Peer Review Academy was feasible on a national scale, resulting in significant qualitative and quantitative improvements in women surgical trainee skillsets, and has the potential to grow and diversify the existing peer review pool.

A retrospective analysis of COVID-19 tracheostomies: Early versus late tracheostomy.

Objectives: To assess the impact of early tracheostomy (ET) versus late tracheostomy (LT) placement on mortality and decannulation rates of COVID patients. Methods: A retrospective chart review was performed of all patients infected with COVID-19 who underwent tracheostomy tube placement in an Ochsner-affiliated hospital from March 2020 to May 2022. Patients were identified using the electronic medical record and data was collated using the "Epic SlicerDicer" tool. Descriptive statistics were gathered and compared between patients who underwent ET placement and those who underwent LT placement. Patient demographics, previous medical history, tracheostomy procedural details, arterial blood gases, complications, and outcomes including time to wean from the ventilator, and time to decannulation were recorded. Results: Two-hundred nineteen patients were included in the study. There were no statistically significant differences in liberation from mechanical ventilation rates between early and LT (62% vs. 55%, p = .19), or in decannulation rates (40% vs. 32%, p = .14). The mean duration of time to liberation from mechanical ventilation for early trach was 13.88 versus 18.17 days for late trach, however, no statistically significant difference was found (p = .12). Similarly, mean duration of time to decannulation was 41.17 days for early versus 47.72 for late trach (p = .15). Conclusion: Contrary to some studies in the literature, the results presented here suggest ETs are not associated with hastened liberation from mechanical ventilation or increased decannulation rates. Further prospective studies may be warranted in assessing the impact of early versus LT in the COVID patient population. Level of Evidence: III.

Implications of COVID-19 in Airway and Swallowing Function.

Objective: The acute treatment and complications of the novel COVID-19 virus have been well studied, but the implications of this novel virus for swallowing function continue to be investigated. The goal of this study is to retrospectively assess airway and swallowing outcomes for those patients who required intensive care unit(ICU)-level care for COVID-19 infection. Study Design: Comparison of swallowing outcomes through diet change in COVID-19 patients in the Ochsner-Louisiana State University (LSU) Hospital ICU. Setting: Ochsner-LSU Hospital (Shreveport, Louisiana). Methods: A retrospective chart review was performed from March 2020 to May 2022 to identify patients with a primary diagnosis of COVID-19. Variables analyzed include age, gender, length of intubation, length of ventilation, airway interventions, use of extracorporeal membrane oxygenation, and diet prior to, during, and after hospitalization for COVID-19 infection. Results: Two hundred and seven patients fit the inclusion criteria. There was a significant difference in discharge diet between those patients who were intubated and those who were not (P = .007). Thirty percent of patients were discharged on a different diet than their baseline with patients on a nonregular diet significantly more likely to discharge to a facility (P = .043). Negative vaccine status was associated with prolonged ICU stay, prolonged duration of intubation, and prolonged duration of ventilation. Conclusion: COVID-19 continues to present novel challenges with new implications and outcomes being discovered in the third year of the pandemic. Further research is necessary to determine the most effective treatment approaches with respect to optimized speech and swallow outcomes.

The art of peer review: Guidelines to become a credible and constructive peer reviewer.

Peer review is a learned skill set that requires knowledge of study design, review construct, ethical considerations, and general expertise in a field of study. Participating in peer review is a rewarding and valuable experience in which all academic physicians are encouraged to partake. However, formal training opportunities in peer review are limited. In 2021, the Association of Women Surgeons and the journal Surgery collaborated to develop a Peer Review Academy. This academy is a 1-year longitudinal course that offers a select group of young women surgical trainees across all specialties a curriculum of monthly lectures and multiple formal mentored peer review opportunities to assist them in developing the foundation necessary to transition to independent peer review. The trainees and faculty mentors participating in the Association of Women Surgeons-Surgery Peer Review Academy compiled a summary of best peer review practices, which is intended to outline the elements of the skill set necessary to become a proficient peer reviewer.

Complementary and Integrative Medicine and the Voice.

Dysphonia is a ubiquitous problem impacting a broad range of people. As communication is central to the human experience, any perturbation of the voice can be frustrating for the patient and the physician. Nutritional, psychological, and physical means of preventing and treating hoarseness have been used by humans since the beginning of written record. Today, we use a selection of these approaches, along with traditional medicine, to alleviate problems of the vocal tract.

Reinke's edema management and voice outcomes.

Objectives: Reinke's edema is a chronic disease of the respiratory tract that occurs in adults with a history of chronic smoke exposure. Also known as polypoid corditis, polypoid laryngitis, and polypoid degeneration of the vocal fold, it is strongly associated with smoking, frequently with vocal misuse/abuse, and occasionally with laryngopharyngeal reflux. Reinke's edema remains a cause of chronic dysphonia that is difficult to manage. This review provides perspectives on current and future management of Reinke's edema. Results: Reinke's edema impacts <1% of the population. The excessive mass is seen in polypoid degeneration results in a loss of pitch control and a rough voice. Women are more likely to present for treatment as the characteristic lowering of vocal pitch is more noticeable in women than men. Multiple grading systems have been proposed within the literature. The current standard of care is surgical excision, after smoking cessation. The microflap technique remains the approach of choice for bulky lesions. Surgical management of Reinke's edema has evolved with the introduction of various lasers into otolaryngologic practice; some which can now be used in the office setting. While many management approaches have been described within the literature, there is a little direct comparison and no obvious superior method of Reinke's edema management. Conclusion: To date, the biology of Reinke's edema is not well understood. Additional research is needed further elucidate the role of uncontrolled reflux in the development and recurrence of Reinke's edema.

Is there Really a Lump in My Throat? The Incidence and Implication of Vocal fold Abnormalities in Patients Presenting with Globus.

OBJECTIVE: To identify the prevalence of vocal fold abnormalities in patients with a primary complaint of globus sensation. Secondly, to determine the relationship between globus, vocal fold abnormality, and patient-reported quality of life questionnaire score. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review was performed to identify all new patients evaluated at a tertiary academic care laryngology practice between January 2018 and December 2018 presenting with a chief complaint of globus. Variables of interest include age, gender, laryngeal symptoms, self-reported quality-of-life questionnaire results, and laryngostroboscopy findings. Questionnaires selected for this investigation include the reflux symptom index (RSI), eating assessment tool-10 (EAT-10), and voice handicap index-10 (VHI-10). RESULTS: Two hundred twenty-eight subjects with an average age of 54 ±17 years, were categorized based on one of three laryngostroboscopic findings: absence of vocal fold abnormality, vocal fold paresis/paralysis (motion abnormality), or a vocal fold mass lesion. Fifty percent of patients reporting globus had a normal laryngeal exam, and 50% had a mass lesion or motion abnormality. Twenty five percent had vocal fold motion abnormality (paresis, paralysis, or supraglottic squeeze); 19% had a mass lesion; and 3% had both a lesion and motion abnormality. The average self-reported survey scores were compared among the three groups. Patients with dysphonia had a significantly higher VHI-10 (P = 0.00), and a significantly higher RSI (P =  0.00) than those without dysphonia. Those patients with dysphagia had significantly higher EAT-10 (P = 0.00) and RSI (P = 0.02) scores than those who did not have dysphagia. Patients with vocal fold motion abnormality had significantly higher VHI-10 than those with normal vocal fold mobility (P = 0.02) CONCLUSIONS: Identifying the etiology of globus presents a significant challenge to laryngologists. Data presented here suggest that vocal fold abnormalities may contribute to the sensation of globus and should therefore be considered in the differential when managing these patients.

Feasibility of machine-delivered sequential massage for the management of lymphedema in the head and neck cancer survivor.

Background: Lymphedema after treatment for head and neck cancer negatively impacts the quality of life and can produce neck tissue stiffness, dysphagia, pain, and swelling. One form of treatment for lymphedema is machine-delivered sequential lymphedema massage, which is home based and self administered. This study was undertaken to determine economic and system access to home-based lymphedema therapy and to measure patient-reported outcomes among those able to access therapy. Methods: This study is a retrospective cohort study of 84 head and neck cancer patients who met the criteria for referral for home-based lymphedema treatment. Patients who were able to access lymphedema therapy were surveyed prior to initiation of therapy and again after therapy. Results: Thirty-five out of 84 patients were approved for home-based therapy and received the equipment. Medicare denial of coverage (21/84) was the most common cause of the inability to access therapy. Of the 35 patients who accessed therapy, presenting complaints included: stiffness (31), pain (29), dysphagia (20), and swelling (19). The average time from completion of cancer treatment to initiation of lymphedema therapy was 9 months. Thirty-four (97%) reported compliance with prescribed therapy, 33 (94%) reported reduced fibrosis, and 30 (89%) reported improvement in activities of daily living. All reported symptoms improved with therapy in 30 (86%) patients. Thirty-two (91%) reported overall satisfaction with home-based lymphedema treatment. Conclusions: Stiffness and pain were the most common complaints of our patients with head and neck lymphedema. Forty-two percent of patients who were recommended home lymphedema machine use were able to obtain this with cost coverage by their insurance company or by donation from the company. We found a high compliance rate and a highly reported improvement in symptoms with the machine. The only identifiable factor for the patients with less improvement in symptoms was a greater time gap between treatment and initiation of use of home lymphedema machine. Level of evidence: 2 Retrospective cohort analysis.

Blue man: Ochronosis in Otolaryngology.

Blue discoloration of the skin and cartilage, or ochronosis, is a rare physical examination finding. We present two cases of childhood onset ochronosis, one exogenous and one endogenous in etiology. The first was caused by minocycline use for severe acne, and the second was caused by congenital alkaptonuria.

Flexible Bronchoscopy Simulation as a Tool to Improve Surgical Skills in Otolaryngology Residency.

OBJECTIVE: To evaluate the benefits of simulation to teach flexible bronchoscopy. STUDY DESIGN: A prospective cohort study to assess the bronchoscopic skills of residents in an otolaryngology training program using a commercially available bronchoscopy simulator. SETTING: Tertiary care otolaryngology residency program. METHODS: Thirty-two otolaryngology residents and 4 expert faculty across 2 academic institutions were assessed on 3 flexible bronchoscopy tasks: diagnostic bronchoscopy, foreign body removal, and tracheal lesion biopsy. Performance was evaluated with a modified version of the validated Bronchoscopy Skills and Tasks Assessment Tool. At 1 of the 2 academic institutions, an additional tool was implemented to evaluate the simulator. RESULTS: There was a correlation between postgraduate training year and time taken to complete tasks, including bronchoscopy, foreign body extraction, and passing through the glottis (P < .001, P = .04, and P < .01, respectively). There was a significant difference between residents and faculty laryngologists for a range of skills and tasks, including percentage of time in middle lumen, contact with bronchial walls, inadvertent esophagus entry, and biopsy of healthy tissue (P < .001, P = .003, P < .001, and P < .001). Additionally, increasing postgraduate level was correlated with a higher percentage of time in the center of the lumen and reduced time to task completion (P = .05 and P < .001). Of 32 residents, 20 evaluated the simulator on its realism, with an average score of 4.1 of 5. CONCLUSION: The commercially available flexible bronchoscopy simulator provides a valid assessment of bronchoscopic skill and is a useful tool for practicing bronchoscopy in a safe, controlled environment. LEVEL OF EVIDENCE: Individual cohort study.

Mainstream Cigarette Smoke Impacts the Mouse Vocal Fold Epithelium and Mucus Barrier.

OBJECTIVES/HYPOTHESIS: Cigarette smoke (CS) is a primary risk factor for the development of numerous benign and malignant laryngeal diseases. The epithelium and mucus lining the vocal folds (VF) are the first barriers against CS. The primary objective of this study was to investigate epithelial and mucus barrier changes in the mouse laryngeal mucosa upon exposure to subacute CS. The secondary objective was to compare mucus barrier changes in mice and human smokers and nonsmokers. Study Design Animal model. METHODS: Mice were exposed to CS for 4 weeks for 4 hours (N = 12, high dose [HD]) or 1 hour (N = 12, low dose [LD]) per day. Air-exposed mice were used as a control group (N = 10). Larynges were harvested and VF epithelial barrier integrity was evaluated including cellular proliferation and expression of cell junctions. We also investigated mucus production by examining mucus cell area and mucin expression in mice and human smokers and nonsmokers. RESULTS: HD CS increased VF epithelial cellular proliferation but did not alter the expression of cell junctions. HD CS also induced hypertrophy of the mucus-producing submucosal glands. However, only LD CS increased MUC5AC gene expression. MUC5AC staining appeared elevated in laryngeal specimens from smokers, but this was not significant as compared to nonsmokers. CONCLUSIONS: These findings help us identify potential adaptive mechanisms to CS exposure as well as set the foundation for further study of key aspects of epithelial and mucus barrier integrity that may be implicated in laryngeal disease development following prolonged smoking.

An Uncommon Cause of Dysphagia: Postpneumonectomy Syndrome.

OBJECTIVE: Dysphagia after pneumonectomy is uncommon but concerning. The purpose of this paper is to present a case of dysphonia secondary to postpneumonectomy syndrome. Case Report. A 66-year-old female with stage IIIa adenocarcinoma of the lung was treated with a left pneumonectomy. Three years later, she presented with severe dysphagia, dyspnea, and dysphonia. Esophagram demonstrated severely deviated esophagus to the left of midline, attributed to prior left-sided pneumonectomy, without clear evidence of any external compression. Chest CT scan showed associated leftward mediastinal shift. This patient was treated with voice therapy and an exclusion diet, as the patient elected not to have surgery. CONCLUSION: This is the first reported case of dysphonia accompanying severe dysphagia following left pneumonectomy. While postpneumonectomy syndrome is rare, a high degree of clinical suspicion is recommended when treating patients with history of pneumonectomy.

Patient Reported Outcomes and Objective Swallowing Assessments in a Multidisciplinary Dysphagia Clinic.

OBJECTIVES/HYPOTHESIS: Dysphagia encompasses a complex compilation of symptoms which often differ from findings of objective swallowing evaluations. The purpose of this investigation was to compare the results of subjective dysphagia measures to objective measures of swallowing in patients evaluated in a multidisciplinary dysphagia clinic. STUDY DESIGN: Prospective cohort study. METHODS: The study cohort included all patients evaluated in the multidisciplinary dysphagia clinic over 24 months. Participants were evaluated by a multidisciplinary team including a laryngologist, gastroenterologist, and speech-language pathologist. Evaluation included a videofluoroscopic swallowing study (VFSS), fiberoptic endoscopic evaluation of swallowing (FEES), and transnasal esophagoscopy (TNE). Data collected included diet (FOIS), Eating Assessment Tool (EAT-10) score, Reflux symptom index (RSI) score, and the findings of the VFSS exam. RESULTS: A total of 75 patients were included in the analysis. The average EAT-10 score was 16.3 ± 2.1, RSI was 21.4 ± 0.6, and FOIS score was 6.0 ± 1.33. VFSS revealed impairments in the oral phase in 40% of the cohort, pharyngeal in 59%, and esophageal in 49%. Abnormalities were noted in one phase for 32%, in 2 phases in 32%, and three phases in 18%. Patients with abnormal pharyngeal findings on VFSS had significantly higher EAT-10 scores (P = .04). Patients with abnormal oral findings on VFSS were noted to have significantly lower FOIS scores (P = .03). CONCLUSIONS: Data presented here demonstrate a relationship between patient reported symptoms and objective VFSS findings in a cohort of patients referred for multidisciplinary swallowing assessment suggesting such surveys are helpful screening tools but inadequate to fully characterize swallowing impairment. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:1088-1094, 2021.

Dysphagia and Dysphonia, a Pairing of Symptoms Caused by an Unusual Pair of Diseases: Castleman's Disease and Myasthenia Gravis.

OBJECTIVES: To describe a case of coincident Castleman's disease and myasthenia gravis that initially presented as rapidly progressive dysphagia and dysphonia and to review the unique pathophysiology of these two uncommon diagnoses. METHODS: Case report and literature review. RESULTS: Castleman's disease, angiofollicular or giant lymph node hyperplasia, is a rare benign lymphoid proliferation. Traditionally, the disease is classified based on histologic and clinical characteristics. Fewer than 10 cases with concurrent myasthenia gravis have been reported. Myasthenia gravis and thymic epithelial tumors are both associated with acetylcholine receptor antibody. While patients with isolated Castleman's disease are usually asymptomatic, those who have concurrent myasthenia gravis and undergo surgical treatment are at increased risk of postoperative myasthenic crisis. Both pre- and postoperative plasmapheresis are suggested to improve muscle strength and prevent severe postoperative complications. CONCLUSIONS: In the setting of multiple cranial neuropathies including velopalatal insufficiency and bilateral ptosis it is important to consider myasthenia gravis. Castleman's disease occurs rarely in conjunction with myasthenia gravis but may increase the risk of myasthenic crisis.

Chemotherapy and dysphagia: the good, the bad, the ugly.

PURPOSE OF REVIEW: Dysphagia is a debilitating, depressing and potentially life-threatening complication in cancer patients that is likely underreported. The purpose of this review is to critically synthesize the current knowledge regarding the impact of chemotherapeutic regimens on swallowing function. RECENT FINDINGS: Those patients with cancers involving the aerodigestive tract, head and neck cancer and oesophageal cancer are at highest risk of developing dysphagia. The most common dysphagia causing toxicity of chemotherapeutic agents is mucositis/stomatitis. The use of cisplatin is correlated with increased incidence of mucositis. Similarly, the addition of melphalan is also associated with worsening mucositis and dysphagia. In some cases of oesophageal cancer, thyroid cancer, metastatic lung or breast cancer the use of chemotherapy can improve swallow function as obstructive lesions are reduced. SUMMARY: There is limited literature regarding the role of chemotherapy in the development or treatment of dysphagia. Most dysphagia that occurs during cancer treatment is attributable to radiation or the synergistic effect of radiation and chemotherapy. Patients with disordered swallowing prior to treatment have the greatest risk of developing posttreatment dysphagia. Studies are needed to determine whether acute inflammation associated with oropharyngeal mucositis predisposes for late dysphagia.

Lessons learned from open laryngotracheal airway resection and primary anastomosis in high risk patients.

OBJECTIVE: Laryngotracheal stenosis is one of the most difficult conditions treated by the Otolaryngologist. Open resection of stenosis with primary airway anastomosis is the definitive treatment for this condition. However, some patients are considered high risk candidates for open airway surgery and management and outcomes in this group have not been reported. The purpose of this investigation is to identify a series of high risk patients who underwent open laryngotracheal surgery and detail the lessons learned in regards to their post-operative course and outcomes. METHODS: A retrospective cohort study of all patients that underwent airway resection and primary anastomosis over a fifteen-year period was performed. High-risk patients, those with medical comorbidities that impair wound healing, were identified. Post-operative course, management of complications, and ultimate airway outcomes were noted. RESULTS: Seven patients fitting the high-risk category were identified. Comorbidities were poorly controlled insulin dependent diabetes mellitus (N = 4), poorly controlled hypertension (N = 4), end stage renal disease requiring hemodialysis (N = 3), chronic obstructive pulmonary disease (N = 1), and history of radiation therapy (N = 1). Each patient suffered postoperative complications of varying degrees including postoperative infection (N = 1), formation of granulation tissue at the anastomotic site (N = 3), and postoperative hematoma (N = 1). Management included treatment of infection and complications. Anastomotic dehiscence was managed with tracheostomy and T-tubes. CONCLUSIONS: High-risk medical comorbidities may not be absolute contraindications for open laryngotracheal resection of airway stenosis. However, this experience emphasizes the importance of preoperative medical optimization and comprehensive postoperative care.
