Longitudinal Assessment of Singing Students.

INTRODUCTION: Singers have unique vocal demands, and if the voice is impaired there can be a negative impact on their quality of life. While a variety of options exist to assess vocal health, the utilization of cepstral peak prominence (CPP) has increased due to his reliability in some situations. However, it has not been utilized commonly in the singing population. This study sought to assess vocal health in singing students using noninvasive measures such as singing voice handicap index (SVHI) and consensus auditory perceptual evaluation of voice (CAPE-V) as well as CPP to provide preliminary information on this measure. METHODS: A prospective longitudinal study of singing students independent of year of training enrolled in a 2-credit voice lesson at an undergraduate School of Music was conducted. Non-invasive measures were used to evaluate the voice. All participants recorded the same spoken sentence at four equally spaced intervals throughout the semester using a ZOOM H4n Pro (two cardioid input microphone, Hauppauge, New Year). Participants completed SVHI at the time of each recording, and CAPE-V conducted by two speech language pathologists trained in voice. CPP was determined using running speech samples. RESULTS: A total of 23 singers completed the study (11 male, 12 female). There was a significant difference in SVHI at the first recording compared to the final recording (10.6 ± 4.6 vs 9.3 ± 5.9, P= 0.008). Similarly, there was a significant difference in CPP at the first recording compared to the final recording (9 ± 3 vs 9.4 ± 1.1, P < 0.001). However, no significant difference was seen with CAPE-V. CONCLUSION: Our results are similar to previous studies. There was no evidence in decline in objective and subjective vocal quality utilizing the measure included in our study.

Acute post-operative airway complications following anterior cervical spine surgery and the role for cricothyrotomy.

Anterior cervical spine surgery (ACSS) is a common procedure, but not without its own risks and complications. Complications that can cause airway compromise occur infrequently, but can rapidly lead to respiratory arrest, leading to severe morbidity or death. Knowing emergent post-operative airway management including surgical airway placement is critical. We aim to review the different etiologies of post-operative airway compromise following ACSS, the predictable timeline in which they occur, and the most appropriate treatment and management for each. We place special emphasis on the timing and proper surgical technique for an emergent cricothyrotomy. Angioedema is seen the earliest as a cause of post-operative airway compromise, typically within 6-12 hours. Retropharyngeal hematomas can be seen between 6-24 hours, most commonly within 12 hours. Pharyngolaryngeal edema is seen within 24-72 hours. After 72 hours, retropharyngeal abscess is the most likely etiology. Several studies have utilized delayed extubation protocols following ACSS based on patient risk factors and found reduced postoperative airway complications and reintubation rates. The administration of perioperative corticosteroids continues to be controversial with high-level studies recommending both for and against their use. Animal studies showed that after cardiac arrest, the brain can recover if oxygenation is restored within 5 minutes, but this time is likely shorter with asphyxia prior to cardiac arrest. Experience and training are essential to reduce the time for successful cricothyrotomy placement. Physicians must be prepared to diagnose and treat acute postoperative airway complications following ACSS to prevent anoxic brain injury or death. If emergent intubation cannot be accomplished on the first attempt, physicians should not delay placement of a surgical airway such as cricothyrotomy.

Practice variations in voice treatment selection following vocal fold mucosal resection.

OBJECTIVES/HYPOTHESIS: To characterize initial voice treatment selection following vocal fold mucosal resection in a Medicare population. STUDY DESIGN: Retrospective analysis of a large, nationally representative Medicare claims database. METHODS: Patients with > 12 months of continuous Medicare coverage who underwent a leukoplakia- or cancer-related vocal fold mucosal resection (index) procedure during calendar years 2004 to 2009 were studied. The primary outcome of interest was receipt of initial voice treatment (thyroplasty, vocal fold injection, or speech therapy) following the index procedure. We evaluated the cumulative incidence of each postindex treatment type, treating the other treatment types as competing risks, and further evaluated postindex treatment utilization using the proportional hazards model for the subdistribution of a competing risk. Patient age, sex, and Medicaid eligibility were used as predictors. RESULTS: A total of 2,041 patients underwent 2,427 index procedures during the study period. In 14% of cases, an initial voice treatment event was identified. Women were significantly less likely to receive surgical or behavioral treatment compared to men. From age 65 to 75 years, the likelihood of undergoing surgical treatment increased significantly with each 5-year age increase; after age 75 years, the likelihood of undergoing either surgical or behavioral treatment decreased significantly every 5 years. Patients with low socioeconomic status were significantly less likely to undergo speech therapy. CONCLUSION: The majority of Medicare patients do not undergo voice treatment following vocal fold mucosal resection. Further, the treatments analyzed here appear disproportionally utilized based on patient sex, age, and socioeconomic status. Additional research is needed to determine whether these observations reflect clinically explainable differences or disparities in care. LEVEL OF EVIDENCE: 2c. Laryngoscope, 126:2505-2512, 2016.

Atraumatic intubation: experience using a 5.0 endotracheal tube without a stylet for laryngeal surgery.

OBJECTIVES/HYPOTHESIS: Vocal fold injury is a well-know complication of intubation, with rates reported as high as 69%. Laryngology textbooks recommend the use of a small endotracheal tube (ETT) to help avoid these complications and optimize visualization. Case reports have suggested that the rigid stylet can lead to laryngeal injury. Given the additional risks, intubation without the stylet is our preferred practice. There is limited documentation in the literature regarding this viewpoint. Our study investigated the feasibility of and potential barriers to intubation using 5.0 ETT without a stylet. STUDY DESIGN: Prospective study. METHODS: Consecutive adult patients undergoing laryngeal surgery were recruited for intubation with a 5.0 ETT without a stylet. Demographic data, specialty and training level of the intubator, and factors that would predict a difficult intubation were recorded. Descriptive statistical analysis was performed. RESULTS: Findings of the participants (n = 67) included average American Society of Anesthesiologists (ASA) physical status classification (2.2), average Mallampati score (1.7), average Cormack-Lehane grade (1.5), and average body mass index (28.0). Five patients (7.4%) required intubation using a stylet, and one of these five participants was intubated initially with a stylet. Of these five participants, 80% required use of a GlideScope (P < .001), and they had significantly higher ASA classification (P = .047) and number of intubation attempts (P = .042). One patient sustained an oropharyngeal injury during intubation with a stylet. No participants had laryngeal injury. CONCLUSIONS: Most patients can be intubated successfully using a 5.0 ETT without a stylet. There were no cases of laryngeal trauma with this technique. LEVEL OF EVIDENCE: 2b.

Chronic facial pain and Meckel cave masses as the initial presentation of neurosarcoidosis: a case report.

Sarcoidosis is a systemic inflammatory disease that can affect virtually every organ system, leading to a wide variety of clinical manifestations. Central nervous system involvement producing neurologic symptoms can occur in patients with sarcoidosis, yet rarely are these symptoms the initial manifestations of the disease. Here we present the case of a 38-year-old man who presented with a history of chronic facial pain, blurred vision, increased lacrimation, and periodontal abscesses. Physical examination revealed no evidence of infection or neoplasm. Magnetic resonance imaging revealed space-occupying lesions in Meckel cave bilaterally, with soft-tissue density extending into the left sphenoid and posterior ethmoid sinuses. Endoscopic biopsy of sinus mucosa demonstrated the presence of noncaseating granulomas and the absence of organisms, findings suggestive of neurosarcoidosis. The diagnosis was further supported by chest radiography, which demonstrated bilateral hilar adenopathy. The patient was treated with corticosteroids, and his facial pain improved markedly. In this article we discuss neurosarcoidosis and its manifestations, diagnosis, and clinical course.
