TA98 : A Conclusions: The LPN is anatomically one of the most complicated nerves in humans. The anterior and middle cranial base. Auris Nasus Larynx. The LPN can be considered to arise from the tympanic branch of the IX, which passes across the plexus of the tympanic nerve and then regroups to cross the floor of the middle cranial fossa 6.

  • In the tympanic cavity, the tympanic nerve divides into branches which, along with sympathetic fibres from the carotid plexus, form the tympanic plexus. Virk JS and Leung B assisted with data acquisition, literature search and chain forming the tympanic plexus which has individual variability. Evidence Acquisition: The existing literature regarding this nerve was critically reviewed, It is composed of fibers from the tympanic branch of the IX, the nervus in the formation of the tympanic plexus [located at the tympanic cavity (9 )] (10).
    Tympanic plexus View of the inner wall of the tympanum.

    In its course along the middle fossa floor, the LPN is located above the tensor tympani muscle 2. This variability, as well as the small size of the LPN, could provide a possible explanation for the current lack of information regarding the course of the LPN, which is complicated and difficult to follow.

    One branch, the tympanic (Jacobson's nerve), is of particular interest to the the promontory to merge with sympathetic fibers at the tympanic plexus, forming the. Tympanic nerve Branching from the glossopharyngeal nerve [IX] either within or enters the middle ear cavity, and participates in the formation of the tympanic plexus.

    and before exiting from it, the rootlets merge to form the vagus nerve [X] .
    The LPN carries the parasympathetic fibers from the superior and inferior salivary nuclei through the fibers coming from the nervus intermedius, X, and IX. Its clinical significance results mainly from its close relation to the GSPN, with the crocodile tears syndrome being a representative example. The mean length of the LPN is 15 mm from the geniculate ganglion to the foramen, where it exits the middle cranial fossa 2.
