The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex. The temporal bones are overlaid by the sides of the head known as the temples, and house the structures of the ears. The lower seven cranial nerves and the major vessels to and from the brain traverse the temporal bone.

An implantable microstimulator and a stimulating electrode are implanted to treat tinnitus. The microstimulator is connected to the stimulating electrode via a short, flexible lead. The electrode is implanted in the promontory of the cochlea or in the cochlear round window niche to deliver electrical stimulation to the auditory nervous system and thereby suppress or mask the tinnitus. The microstimulator may be surgically implanted through the ear canal, via a mastoidectomy or through the middle fossa, i.e., a supra-meatal approach. The microstimulator may be placed in middle ear cavity, a bony recess created in the bone surrounding the middle ear, the mastoid, the cochlea or a part of the temporal bone. In addition, the system may further include a test electrode, a test stimulator and a remote programming device that employs a bi-directional radio-frequency communication link to control and program the microstimulator and the test stimulator.

Model-based tomographic reconstruction with correlated measurement noise
The present invention is directed to a novel tomographic reconstruction framework that explicitly models the covariance of the measurements in the forward model using a mean measurement model and a noise model. This more accurate model can result in improved image quality, increased spatial resolution, and enhanced detectability—in particular, for imaging scenarios where there are features on the order of the correlation length in the projection data. Applications where these methods might have particular benefit include high resolution CBCT applications as in CBCT mammography (where very fine calcifications are difficult to resolve due to detector blur and correlation), musculoskeletal imaging (where fine bone details are important to the imaging task), or in temporal bone imaging where the fine detail structures of the inner ear are also difficult to resolve with standard imaging techniques.

A maxillary, mandibular, or dual concussion orthotic that substantially reduces concussion resulting from forces applied to the lower jaw, and a method of producing the orthotic. The orthotic device produced according to the method described herein is objectively measured and produced to physiological parameters for an individual user. The orthotic is constructed so that the mandibular teeth are firmly indexed into the orthotic to hold the mandible in a specific position relative to the maxilla. The upper and lower jaws are positioned by the orthotic to act as a unit, and cooperate with the orthotic to effectively dissipate concussive forces and provide spacing of the temporomandibular joint, resulting in the decompression of the joint to mitigate transmission of concussive forces from the condyles of the mandible to the temporal bones of the skull.
