Conclusion
Maxillary nerve is commonly involved in carcinoma of nasopharynx,
palate,
maxilla,
lip- the locations for abnormality to look for are foramen rotundum,
cavernous sinus and pterygopalatine fossa.
Mandibular nerve is commonly involved in carcinoma of mandible,
retromolar trigone,
masticator and parapharyngeal space- the locations for abnormality to look for are foramen ovale,
cavernous sinus,
mandible and inferior alveolar canal.
Facial nerve is commonly involved in carcinoma temporal bone,
parotid,
external auditory canal,
skin- the locations for abnormality to look for are course along the temporal bone,
parotid space and stylomastoid foramen.
• Cranial nerve anatomy and pathways of perineural spread should be familiarized,
since it is very important for adequate staging and treatment planning.
