Although radiotherapy has been generally accepted as the treatment of
choice for nasopharyngeal carcinoma (NPC), NPC at the primary site is
not always controlled by this therapy. We performed surgical treatment
to eradicate such residual tumor through a transmandibular, transpter
ygoid approach, on four patients with local residual NPC after curativ
e radiotherapy. Two patients survived with no evidence of disease for
more than 6 years. The other two patients died of multiple metastases
to the liver or bone at 4 years and at 6 months after treatment. Howev
er, the nasopharynx remained free of disease in these two patients. Al
though the number of patients in the present series is small, surgical
treatment of local persistent tumor after radiotherapy was beneficial
. The indication for this technique is tumor in the nasopharynx extend
ing to the parapharyngeal space, not invading intracranially. The tran
smandibular, transpterygoid approach offers a wide operative field wit
h minimal postoperative morbidity, making it possible to manage the in
ternal carotid artery easily.
