[Usefulness of CT scan in secretory otitis media in patient with nasopharyngeal carcinoma].
OBJECTIVE
To explore the usefulness of CT scan in nasopharyngeal carcinoma (NPC) with secretory otitis media (SOM).


METHODS
CT of the nasopharynx and mastoid in 127 cases with NPC pro- and post-irradiation were analyzed.


RESULTS
Total incidence rate of SOM was 59% before irradiation. The incidence corresponded to T stage and tumor location of NPC. In the patients without SOM before irradiation, 70 percent of the ears developed SOM, and the peak stage of the formation of SOM was in three to six month after irradiation.


CONCLUSIONS
CT scan for the patient with NPC is useful for the diagnosis and prognosis of SOM induced by NPC.
