Objective:
Here we report our experience of patients with squamous cell carcinoma (SCC) of the nasal cavity and ethmoid sinus (NC&ES) together with an analysis of treatment outcomes.
Methods:
A retrospective analysis was performed using data from 25 consecutive patients treated between 2000 and 2012. Four patients were diagnosed with T1, 3 with T2, 4 with T3, 7 with T4a, and 7 with T4b disease. No patient had lymph node metastasis.
Results:
Twelve patients were treated with surgery with/without radiotherapy and with/without chemotherapy. Of these, 4 underwent endoscopic surgery without an open approach and 3 required an anterior skull base approach. Thirteen were treated with radiotherapy; 1 with radiotherapy alone, and 4 and 8 with intravenous and intra-arterial chemotherapy, respectively. The 5-yr overall survival for T1-3, T4a, and T4b disease was 53.9%, 71.4%, and 29.0%, respectively. The 5-yr disease-specific survival for T1-3, T4a, and T4b disease was 74.1%, 71.4%, and 29.0%, respectively.
Conclusion:
Our treatment policy for patients with SCC of NC&ES, which basically follows the NCCN guideline, was considered to be appropriate. However, several points in terms of surgery and non-surgical approach remain to be solved through further research.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
