I'm a pgy-1 going into otolaryngology.
I can address a few things for you guys.
The term "ENT" is not a 4-letter word for Otolaryngology-Head and Neck Surgery. Nobody I know answers pages as "Hi, I'm the otolaryngology-head and neck surgery resident on call." I don't think there's anything wrong with saying "ENT." However, I would never put "ENT" on my white coat, business cards, publications, office, etc. It's just easier to say "ENT."
The average USMLE Step 1 score of a matched applicant for the 2002 match was 233, not 237. This is down from 2001 (236) and down from 2000 (234). I'm sure it's not statistically significant, however. The average USMLE Step 1 score of someone who didn't match was 214. This is up from 2001 (213) and 2000 (213). I'm definitely sure this isn't statistically significant. The SF Match used to publish this data; instead it is mailed directly to applicants.
85% of US seniors who applied for otolaryngology matched (taking 233 of 250 spots). 40% of US grads who applied matched. 27% of FMG who applied matched.
ENT is definitely one of the most competitive and exclusive residency programs. I would say that dermatology is still more competitive. As far as scores go, I think it's more competitive than radiology, ophthalmology, orthopedics, neurosurgery, and urology; however, based on popularity, ortho and rads may have higher unmatch rates. (That's just my impression.)
