  • tongue paresthesia and dysgeusia following operative Microlaryngoscopy
    Annals of Otology Rhinology and Laryngology, 2006
    Co-Authors: Belachew Tessema, Guopei Yu, Lucian Sulica, Richard B Sessions
    Abstract:

    Objectives:This study was performed to assess the overall incidence and duration of alterations in tongue sensation and taste after operative Microlaryngoscopy, and the relation of these symptoms to operative time.Methods:We performed a retrospective review of information regarding tongue symptoms in patients who completed standard post-Microlaryngoscopy follow-up at 1 week, 1 month, and 3 months.Results:One hundred patients (54 male and 46 female; mean age, 46 years; age range, 14 to 83 years) met the inclusion criteria. Eighteen patients had positive findings at 1 week: 15 complained of paresthesia and 3 of dysgeusia. The symptoms decreased over time without treatment (4% of patients at 1 month and 1% of patients at 3 months). Only 1 case of dysgeusia persisted past 3 months. Gender was found to be a significant independent risk factor for the development of symptoms (odds ratio, 5.63; 95% confidence interval, 1.36 to 31.29; p = .013). Patients whose operations lasted longer than 1 hour were almost 4 ti...

Eighteen patients had positive findings at 1 week: 15 complained of paresthesia and 3 of dysgeusia. The symptoms decreased over time without treatment (4% of patients at 1 month and 1% of patients at 3 months). Only 1 case of dysgeusia persisted past 3 months. Gender was found to be a significant independent risk factor for the development of symptoms (odds ratio, 5.63; 95% confidence interval, 1.36 to 31.29; p = .013). Patients whose operations lasted longer than 1 hour were almost 4 times more likely to develop tongue-related symptoms than those with an operative time less than 30 minutes, although these findings did not achieve statistical significance (odds ratio, 3.91; 95% confidence interval, 0.62 to 30.95; p = .182). Conclusions: Alterations in tongue sensation and taste, most likely due to lingual nerve injury, are common after Microlaryngoscopy, especially in female patients. They also tend to be associated with longer operative times. Although transient in nearly every case, lingual paresthesia and dysgeusia should form part of the preoperative discussion with the patient.

  • voice rest after Microlaryngoscopy current opinion and practice
    Laryngoscope, 2003
    Co-Authors: Alison Behrman, Lucian Sulica
    Abstract:

    OBJECTIVE: Although voice rest is often recommended after excision of benign mucosal vocal fold lesions, no standard of care exists regarding the use, duration, or extent of vocal restrictions. This prospective study is intended to explore current opinions and practices of otolaryngologists regarding the use of complete and relative voice rest. STUDY DESIGN AND METHODS: A 16-item survey was mailed to all active U.S. members of the American Academy of Otolaryngology-Head and Neck Surgery (n = 7,321) regarding use of complete and relative voice rest after surgical excision of vocal fold nodules, polyps, and cysts. Treatment preference questions used a Likert 5-point scale with end anchors of 1 equaling "never" and 5 equaling "always". RESULTS: The response rate was 16.5% (1,208 respondents). Differences by lesion type were not statistically significant, suggesting that surgeons consider the mucosal disruption resulting from the surgery to be similar across lesions. Approximately 51.4% (620) favored complete voice rest. Approximately 62.3% (753) favored relative voice rest. Approximately 18% (213) of the respondents who "always" recommend complete rest also "always" recommend relative rest. The most common duration for both types of rest is 7 days. CONCLUSIONS: There is a clear preference for the use of voice rest, but the specific type (complete or relative) is controversial, and a notable percentage of respondents (15%) do not favor any type of voice rest. It is likely that the lack of uniformity of opinions and practices reflects the absence of empirical data. Prospective clinical trials are needed to guide clinical standards of care.

  • validation of an operating room immersive Microlaryngoscopy simulator
    Laryngoscope, 2012
    Co-Authors: Jason Fleming, Nick Sevdalis, Karan Kapoor, Meredydd L Harries
    Abstract:

    Objectives/Hypothesis: To assess the face and construct validity of two assessment tools for a Microlaryngoscopy simulator—a Checklist Assessment for Microlaryngeal Surgery and Global Rating Assessment for Microlaryngeal Surgery. Study Design: Blinded experimental simulator-based study. Methods: There were 15 candidates divided into a novice (≤50 procedures performed) or experienced (>50 procedures) group depending on their previous Microlaryngoscopy experience. Each candidate undertook a 10-minute simulation of a Microlaryngoscopy and excision biopsy, and two blinded experts rated their performance live on each of the two assessment tools. To assess face validity, each candidate subsequently completed a questionnaire about the simulator. Results: The model demonstrated good face validity across all levels of experience. The global rating assessment demonstrated excellent interrater reliability (0.9) compared to the checklist assessment (0.7). The checklist assessment was able to differentiate experienced and novice candidates and therefore demonstrated construct validity. The global rating tool, however, was unable to differentiate candidates. There was a significant correlation between the two assessment tools (correlation coefficient = 0.624). Conclusions: This study is the first reported study of a high-fidelity Microlaryngoscopy simulator with task-specific rating tools. Use of these tools is recommended within otolaryngology training programs, with the global rating assessment for use as a frequently used feedback tool, and the checklist assessment as a confirmatory evaluation of competency at transitions of professional training.

  • validation of a theater based immersive Microlaryngoscopy simulator
    Otolaryngology-Head and Neck Surgery, 2011
    Co-Authors: Jason Fleming, Nick Sevdalis, Meredydd L Harries, Karan Kapoor
    Abstract:

    Objective: Assess the face and construct validity of 2 assessment tools: a Checklist Assessment for Microlaryngeal Surgery (CAMS) and a Global Rating Assessment for Microlaryngeal Surgery (GRAMS) on a new theater-based immersive microlaryngscopy simulator.Method: Fifteen candidates were divided into the novice or experienced group depending on their previous Microlaryngoscopy experience. Each candidate undertook a 10-minute simulation of a Microlaryngoscopy and excision biopsy, and 2 blinded experts rated their performance live. Candidates subsequently completed a questionnaire on their opinion of the simulator.Results: The model demonstrated good face validity across all levels of experience. The GRAMS demonstrated excellent interrater reliability (0.9) compared with the CAMS (0.7). The CAMS assessment was able to differentiate experienced and novice candidates and, therefore, demonstrated construct validity. The GRAMS tool, however, was unable to differentiate candidates. There was a significant correla...

  • successful use of high flow nasal cannula for concurrent vocal cord electromyography and tubeless microlaryngeal surgery in a spontaneously breathing adult patient a case report
    A&A practice, 2020
    Co-Authors: Sungjin A Song, Nita Sahani, Alvaro Macias, Phillip C Song, Jeremy Juang
    Abstract:

    : Ventilation during Microlaryngoscopy previously included jet ventilation, microlaryngeal endotracheal tubes, and extended apnea. Historically, apneic oxygenation provided a tubeless field but limited operative time. Increased utilization of high-flow nasal cannula in intensive care units and operating rooms has created new opportunities to expand tubeless Microlaryngoscopy. Although few studies have described high-flow nasal cannula for Microlaryngoscopy, there remains much to be explored. In this case report, we describe the unique setting of utilizing high-flow nasal cannula in a spontaneously breathing patient to create an optimal tubeless surgical field for both Microlaryngoscopy and vocal cord electromyography.

  • force metrics and suspension times for Microlaryngoscopy procedures
    Journal of Voice, 2019
    Co-Authors: Phillip C Song, Allen L Feng, Elefteria Puka, Alex Ciaramella, Robert T Sataloff, Matthew R Naunheim
    Abstract:

    Summary Objective To determine the difference in force metrics measured by the laryngeal force sensor for various suspension Microlaryngoscopy (SML) procedures and their perioperative narcotic requirements. Study Design Prospective observational study. Setting Academic tertiary center. Methods The laryngeal force sensoris a force sensor designed for SML procedures. Prospectively enrolled patients had dynamic recordings of maximum force, average force, suspension time, and total impulse. Procedures were grouped into excision of striking zone lesions, nonstriking zone lesions, endoscopic cancer surgery with margin control, and airway dilation. Narcotic administration in the intraoperative period and postanesthesia care unit was also recorded and converted into IV morphine equivalents. Surgeons were blinded to the force recordings during surgery to prevent operator bias. Results In total, 110 patients completed the study. There was no significant difference in average force across different procedures, however, a significant difference was seen for maximum force (P = 0.025), suspension time (P Conclusion Significant differences in force metrics exist between various SML procedures. Endoscopic cancer surgery is associated with higher force metrics and perioperative narcotic requirements.
