OBJECTIVE: To explore the value of nasopharyngo-fiberscope and CT in diagnosing microfocal Nasopharyngeal Carcinoma (NPC) and the prevalent area, the nasopharynx, where the NPC usually initially developed from.
METHOD: From October, 2003 to October,2005, the data of original microfocus of 36 pathologically confirmed NPC were reviewed retrospectively. These cases were examined by nasopharyngo-fiberscope and CT strengthening scanning.
RESULT: On clinical examination, only 2 cases (5.6%) were found to have original micro-tumor in the recess, the other 34 cases (94.4%) had developed from the other regions including 25 (69.4%) from the roof and 9 cases (25.0%) from the posterior wall, all with smooth and symmetrical mucosa in the recess. Positive rate of nasopharyngeal mass were 100% by nasopharyngo-fiberscope and by CT.
CONCLUSION: The data suggested that the roof of nasopharyngeal cavity be the most possible area that the original NPC micro-focus developed from, followed by the posterior wall and the recess. Nasopharyngo-fiberscope and CT is very helpful for the correct clinical diagnosis of NPC.
