Nerve Temporal Deep Posterior

Nerve temporal deep posterior, or n. temporalis profundus posterior (bna, jna), is one of the nerves that are part of the trigeminal nerve. It is responsible for the innervation of the temporal region, including the skin of the temporal region and the parotid salivary gland.

The deep posterior temporal nerve begins from the geniculate ganglion, which is located on the lateral wall of the midbrain, and passes through the posterior cranial fossa to the temporal region. It passes through the temporal foramen and then divides into two branches: superficial and deep. The superficial branch passes through the temporomandibular joint and innervates the skin of the temporal region. The deep branch passes through the pyramid of the temporal bone and innervates the parotid gland, as well as the skin of the temporal and parotid regions.

Dysfunction of the deep posterior temporal nerve can lead to various diseases such as ear infections, Bell's palsy, facial palsy, hearing and visual impairment, as well as other diseases associated with the temporal region.

Various methods are used to treat deep posterior temporal nerve dysfunction, such as medication, physical therapy, surgery and other methods. It is important to see a doctor to diagnose and treat a condition related to the deep posterior temporal nerve.
