Abstract:
Temporal bone squamous cell carcinoma (TBSCC) is rare
and poses difficulties in diagnosing, staging and
management. We describe a case series with six patients
who were diagnosed TBSCC, from January 2009 to June
2014, with median age of 62 years old. All patients presented
with blood-stain discharge and external auditory canal
mass, showing that these findings should highly alert the
diagnosis of TBSCC. Three patients staged T3 and another
three with T4 disease. High-resolution CT (HRCT) temporal
findings were noted to be different from intraoperative
findings and therefore we conclude that MRI should be done
to look for middle ear involvement or other soft tissue
invasion for more accurate staging. Lateral temporal bone
resection (LTBR) and parotidectomy was done for four
patients with or without neck dissection. Patients with
positive margin, perineural invasion or parotid and glenoid
involvement carry poorer prognosis and postoperative
radiotherapy may improve the survival rate. One patient had
successful tumor resection via piecemeal removal approach
in contrast with the recommended en bloc resection shows
that with negative margin achieved, piecemeal removal
approach can be a good option for patients with T2-3
disease. In general, T4 tumor has dismal outcome
regardless of surgery or radiotherapy given.
