Objectives: Preliminary data suggest efficacy for the endoscopic approach for sinonasal malignancy. The purpose of this study is to evaluate the effectiveness of the endoscopic approach for the resection of sinonasal squamous cell carcinoma (SCC).
Study Design: Retrospective analysis of patients undergoing endoscopic resection of sinonasal SCC from August 1996 to May 2004.
Methods: Eleven patients were treated with curative intent. Demographic data, histopathology, extent of tumor involvement, and need for adjunctive radiation or chemotherapy were determined. Local recurrence (LR), distant metastasis, overall survival (OS), and disease-free survival (DFS) rates were calculated.
Results: The mean age for the patient population was 62.5 (52-85) years with a male:female ratio of 8:3. Multimodality therapy including radiation or chemotherapy was used in 8 of 11 (73%) patients. Seven patients were resected using strictly an endoscopic approach, whereas four required combined endoscopic and neurosurgical resection. LR and distant metastatic rates were 20% and 0%, respectively. OS and DFS were both 91%, with mean follow-up of 31.5 (range 6-88) months.
Conclusions: Endoscopic resection in combination with multimodality therapy is an effective method for curative resection of sinonasal SCC. In this preliminary study, it facilitated complete resection with acceptable LR and DFS rates.

Background: In sinonasal cancer (SNC), treatment with proton therapy (PT) provides excellent local control, especially after gross total resection. Because of the heterogeneity and rarity of this disease site, a comprehensive assessment of toxicity, survival, and control rates is lacking. Our primary objective was to assess the toxicity outcomes of PT in SNC patients, with a secondary aim of assessing survival and tumor control after PT.

NUT carcinoma (NC) is an extremely rare, aggressive malignancy characterized by chromosomal rearrangements in the (nuclear protein in testis) gene. It usually affects younger patients with a median age of diagnosis at 23 years old. The mainstay of treatment consists of combination chemotherapy, surgical resection, and high dose radiation.

Background: Olfactory neuroblastoma (ONB) is a rare sinonasal malignancy primarily treated with surgery. For tumors arising from the olfactory area, traditional treatment involves transcribriform resection of the anterior cranial fossa. Surgery can be performed with unilateral or bilateral resection depending on extent of involvement; however, there are currently no studies comparing outcomes between the two.

Squamous cell carcinoma is the most common malignancy affecting the sinonasal tract. Local recurrence is the main pattern of treatment failure, affecting nearly half of patients treated for primary sinonasal squamous cell carcinoma (SNSCC). Due to disease rarity and heterogeneity of practices, there are limited guidelines for how to diagnose and care for these patients.
