An unusual case of fluctuating tinnitus that was caused by the occurrence of posttraumatic facial nerve synkinesis to the stapedius muscle is presented with preoperative, operative, and postoperative supportive data.

We present an extremely unusual case of an extratemporal facial nerve malignant peripheral nerve sheath tumor (MPNST) arising from preexistent intratemporal neurofibroma, illustrating a difficulty in discriminating between perineural spread of the MPNST and the preexistent intratemporal neurofibroma on preoperative radiographic images. The most interesting point was that preoperative CT scan and MR images led to misinterpretation that MPNST extended proximally along the facial nerve canal. It is important to recognize that the intratemporal perineural spread of neurofibromas and MPNST share common imaging characteristics. This is the first report (to our knowledge) of these 2 lesions coexisting in the facial nerve, leading to misinterpretation on preoperative images.

A series of experiments on guinea pigs was conducted to determine the prognostic dependability of the stapedial reflex measurement in Bell's palsy. Comparison of the threshold of evoked electromyographic response of the stapedius muscle with that of the orbicularis oris muscle revealed that the stapedial nerve had a lower excitability than did the nerve innervating the orbicularis oris muscle. This lower excitability correlates with the histological finding that the stapedial nerve fibers have a smaller average diameter. The results indicate the resistance of the stapedial nerve to injury of the facial nerve. Functional recovery after cramping of the facial nerve tended to occur later in the stapedial nerve than in the nerve innervating the orbicularis oris muscle. The resistance of the stapedial nerve and the longer period required to recover function in this nerve were factors influencing the prognostic ambiguity of this test.

AbstractAn unusual case of a labyrinthine sequestrum is presented. During mastoidectomy on a patient with chronic recurrent mastoiditis, a large sequestrum in the labyrinth was found. Four years earlier he had been treated for a posterior fossa abscess, which had followed acute otitis media. An extensive ablative and drainage procedure of the pars superior and pars inferior with preservation of the facial nerve was indicated in this patient.

We present an unusual case of physical discomfort, as opposed to objective or subjective tinnitus, caused by a unilateral acoustic reflex. The cause of the discomfort was identified audiologically by the use of acoustic impedance audiometry. The dull pain that was elicited upon contraction and relaxation of the stapedius muscle was eliminated with sectioning of the stapedial tendon. No explanation of the mechanism for the pain is suggested at present.
