Which of the following is not decreased with the use of extracapsular dissection for parotid tumors (as opposed to facial nerve dissection techniques)?

A) Temporary facial nerve palsy
B) Permanent facial nerve palsy
C) Frey's syndrome
D) Salivary fistula

View Answer

Answer: Salivary fistula

A total of 2988 patients were included in this study. The analysis showed that the increasing performance of extracapsular dissection was associated with a progressive reduction in the incidence of temporary facial nerve palsy, permanent facial nerve palsy and Frey's syndrome, while the rate of salivary fistula remained the same.

Analysis

Only about one quarter of otolaryngologists answered correctly.

Extracapsular dissection for parotid tumors

Surprisingly the distribution of answers from head and neck surgeons is split across the board. The most popular answer by far was Frey’s syndrome with more than a third of ENTs (35%) submitting this answer. The least popular answer was Permanent facial nerve palsy (19%), while the correct answer, Salivary fistula (24%), and Temporary facial nerve palsy (22%)  were answered nearly the same amount of the time.

About DosedDaily

As an Otolaryngology-Head and Neck surgery resident, like all residents, I found that the performance of my clinical duties left little time for reading and learning. I decided early on that, with a little time each day, I would try to answer just one “Question”. That question might be clinical, basic science, or a pimp question I had missed from an attending. This took only 10-15 minutes each day, but allowed me to research over 350 questions each year in a unrushed, unhurried fashion that improved my learning and retention. This was the best learning experience of my residency.

When I started my academic career, I began intermittently emailing questions to my residents and the term e-pimp was coined by one of them. The name stuck. I began doing daily e-pimps for my residents, and then expanded to residents all over the country. Before long, colleagues in practice were asking to be included, so I had the service accredited for CME, renamed it to DosedDaily given e-pimp's proclivity for spam filters, and the response has been phenomenal. I hope we can make reading and learning a short, daily experience for all clinicians over time.
