POINTS ONLY : ENT (Oto-Rhino-Laryngology)

These section of 'POINTS ONLY ' consists of random points of very importance in each subjects, asked previously in many exams and  made specifically for the purpose of quick revision.

1. HO's Triangle / Supraclavicular fossa --  involvement of this region in Nasopharyngeal carcinoma is N3b irrespective of the size of the tumor. T4 in NP Ca is involvement of orbit, cranial nerves, infratempral fossa, hypopharynx.

NOTE: Even a 6cm node in NP Ca is considered to be N1 and not N2 as in other Head and Neck Cancers.

Extension into the PNS is T3.
