Sleep Medicine for Surgeons:

Otolaryngology sleep medicine curriculum objectives as determined by sleep experts

PURPOSE

(1) Ascertain the most important concepts and topics for otolaryngology resident education in sleep medicine and surgery, as determined by faculty who teach sleep medicine to otolaryngology residents. (2) Create learning objectives within the area of otolaryngologic sleep medicine in order to design a sleep medicine curriculum for otolaryngology residents.

MATERIALS AND METHODS

Two web-based surveys were sent to 163 academic otolaryngologists who teach sleep medicine. The first survey determined the topics, and their relative importance, considered most vital to learn during otolaryngology training. Using the Delphi method, the second clarified questions regarding topics determined by the first survey. Sleep medicine learning objectives for residents were ascertained from responses.

RESULTS

The response rate of first and second surveys were 24.5% and 19%, respectively. Topics ranked most important for resident education included upper airway anatomy, polysomnogram interpretation, and understanding the range of medical and surgical therapies used to treat sleep disorders. Respondents listed surgical therapy as the most critical topic that most residents do not understand well. The second survey clarified the specific anatomic features, surgical techniques, and polysomnography data points deemed most critical for resident learning.

CONCLUSIONS

Academic otolaryngology sleep experts hold opinions regarding relative value of different topics for teaching sleep medicine, which is useful in creating a curriculum for otolaryngology residents. Otolaryngology learning objectives related to sleep medicine identified during this study are being used to create an online curriculum to supplement resident education.

National Institutes of Health Funding for Obstructive Sleep Apnea: An Opportunity for Otolaryngologists

OBJECTIVE

To describe current levels and trends of funding for the National Institutes of Health (NIH) in obstructive sleep apnea (OSA) and to recognize the current status of otolaryngologists in OSA research.

STUDY DESIGN

Scientometric analysis.

METHODS

The NIH RePORTER database was queried for the search term "obstructive sleep apnea" for all available years. Sex, degree, academic department, NIH funding source, geography, funding totals and years, and h-index of principal investigators (PIs) were collected and summarized.

RESULTS

A total of 397 projects spanning 1242 total funding years were funded. Of the 273 individual PIs, 33.3% (91/273) were female. Regarding credentials, 52.4% of PIs (143/273) were MD or MD/PhD, and 41.0% (112/273) were PhD alone. Academic departments of PIs were most often medicine (34.1%), pediatrics (12.1%), cell biology/physiology (10.6%), and psychiatry (7.7%). Seven otolaryngology faculty members had received NIH funding for OSA research (2.6% of total PIs) since 2000. They accounted for 8 grants (0.25% of total grants) and $7,235,729 (1.5% of total dollars) of research funding.

CONCLUSION

Despite studies showing increasing levels of OSA surgery being performed and major areas of research and clinical opportunity, otolaryngologists represent a small minority of OSA research funding. This information may help direct our specialty when setting priorities regarding research funding, as research into the basic science and clinical management of OSA represents a broad and interdisciplinary pursuit.

Development of a computational biomechanical model of the human upper-airway soft-tissues toward simulating obstructive sleep apnea

Numerous challenges are faced in investigations aimed at developing a better understanding of the pathophysiology of obstructive sleep apnea (OSA). The anatomy of the tongue and other upper-airway tissues, and the ability to model their behavior, are central to such investigations. We present details of the construction and development of a soft-tissue model of the human upper airway, with the ultimate goal of simulating obstructive sleep apnea. The steps taken to produce a representative anatomical geometry, of which the associated muscle histology is also captured, are documented. An overview of the mathematical models used to describe tissue behavior, both at a macro- and microscopic level, is given. A neurological model, which mimics the proprioceptive capabilities of the body, is described as it is applies to control of the active dynamics of the tongue. A simplified scenario, which allows for the manipulation of several environmental influences, is presented. It is demonstrated that the response of the genioglossus is qualitatively similar to that determined through experimental techniques. Furthermore, insights into the stress distribution developed within the tongue are discussed. It is shown that changes in almost any aspect of the breathing or physiological conditions invoke a significant change in the response of the airway dilators. The results of this study provide further evidence of the importance of modeling and simulation techniques as an aid in understanding the complex behavior of the human body.

Sleep Medicine Clinical and Surgical Training during Otolaryngology Residency

Objective. The authors sought to assess the otolaryngology residency training experiences in adult sleep medicine and sleep surgery in the United States.

Study Design. Internet survey.

Setting. US academic otolaryngology residency programs.

Subjects and Methods. This Internet survey was emailed to the program directors of 103 US Accreditation Council for Graduate Medical Education (ACGME)–approved otolaryngology residency programs in 2010.

Results. A total of 47 program directors responded, representing 46% of programs surveyed. In 59% of these programs, there was at least 1 faculty member with clinical practice dedicated to adult medicine. Most commonly, these clinicians spent less than 50% of their clinical time on adult sleep medicine. While most otolaryngology residents were reported being well trained in commonly performed procedures such as septoplasty and uvulopalatopharyngoplasty (UPPP), the training on hypopharyngeal or multilevel surgeries, such as partial glossectomy, tongue base resection, hyoid or tongue suspension, or geniotubercle advancement, was considered less frequent. The overall exposure to education regarding the interpretation of original data of laboratory-based sleep studies or portable home monitoring devices was infrequent. A significant portion of respondents indicated that they would like to expand their residents’ exposure to adult sleep medicine and sleep surgery.

Conclusion. This survey provides a starting point to further assess the rigor of sleep medicine/sleep surgery training in US residency programs. Continued assessment and strengthening of the current curriculum are crucial to keep residents up to date with this evolving field. This result calls attention to the importance of bolstering sleep medicine and surgery curriculum to meet the academic requirements of otolaryngology training.
