How is the sensory nerve supply to the nose mapped ?
- Olfactory fibers are located in the superior portion of the internal nose and serve the sensory function of smell.
- The sensory innervation of the skin of the root of the nose is derived from the supratrochlear and infratrochlear branches of the ophthalmic nerve.
- Branches of the infraorbital nerve supply the skin on the lower half of the nose’s side.
- Nasociliary branches of the ophthalmic nerve supply the skin over the lower dorsum of the nose down to the tip.
- The trigeminal nerve supplies general sensory innervation to the anterior internal nose through the anterior ethmoidal, external, and internal nasal branches.
- The lateral posterior superior, pharyngeal, \and lateral posterior inferior branches of the maxillary nerve supply the posterior portion.
- The terminal branches of the infraorbital nervesupply the lining of the nasal vestibule.
- The internal nasal (anterior ethmoidal) and medial posterior superior branches supply the septum anterior and posterior portions, respectively.
