Thank you for answering my previous post, on nerves a few days back. You mentioned the peri-orbit. Could you tell me what nerves are involved in the peri-orbit? Could trauma to the front teeth cause lesions in the Peri-orbit? Does it seem unusual that my skin is not numb, just deep inside my face? I understand that some nerves in the face communicate with each other , specifically the nasopalatine and the anterior dental. What would be the result if this communication was blocked? How can a nerve be intermittantly compressed? What could be compressing it? Can lesions repair themselves? Sorry for so many questions, but this is a huge problem for me and very hard to understand. Your answers are appreciated.

Thanks for your feedback and question. The peri-orbital region is mostly
innervated by the superior (ophthalmic) division of the trigeminal nerve.
More specifically, the Supraorbital nerve innervates the forehead and the
scalp, and the Supratrochlear nerve, the bridge of the nose, medial part
of the upper eyelids. The lacrimal nerves innervate the lateral portion
of the upper eyelids, the conjuctiva. The sensory input from the maxilla,
the region below the eyes, is provided by the middle (maxillary) division
of the trigeminal nerve. More especifically, the zygomaticofacial nerve
innervates the prominence of the cheek.
The nasopalatine nerve is one of the branches of the palatine nerves which
innervate the soft and hard palates. The upper teeth are innervated by
another group of branches from the maxillary nerve, the superior alveolar
nerves (dental nerves). The nasopalatine and dental nerve fibers will
join to form a branch of the maxillary nerve, but they do NOT "communicate"
with each other. The best analogy to the different nerve branches is a
"bundle" of electrically-insulated independent wires - they are within the
same "cable", but information do NOT "jump" from one wire to another.
A trauma can result in the formation of scar tissues beneath the skin and
"tighten" the spaces through which the nerve branches have traverse. Because
of the relatively rich facial musculature, such anomalous scar or chronic
inflammatory tissues can intermitently impinge on the nerves, depending
on the contraction of the facial musculature. It is often difficult to
identify the exact point of compression, therefore surgical repair or
release is not often tried. It is also difficult to predict a resolution
of this process, despite the frustation that this type of lesion causes
to the patients.
I hope this information is helpful. Best of luck.
