Microscopic dissection of 20 human temporal bones revealed that the nerve of Jacobson gave rise to a hypotympanic branch in 50% of the specimens. The fact that the branch was frequently covered by promontory bone and was difficult to approach by the standard tympanotomy technique may explain the 21% failure rate as reported in the literature.
