Poorly differentiated sinonasal carcinomas are a heterogenous group of aggressive neoplasms that encompasses squamous cell carcinoma including basaloid variant, lymphoepithelial carcinoma, sinonasal undifferentiated carcinoma, and neuroendocrine-type small cell carcinoma. We herein describe 3 cases of a hitherto unreported variant combining features of basaloid carcinoma with variable interming...
OBJECTIVES The use of endoscopic approaches for sinonasal malignancy resection has increased, but survival data are limited secondary to disease rarity and new surgical technique. Here we present a systematic review and meta-analysis of endoscopic endonasal resection of sinonasal malignancy. DATA SOURCES MEDLINE, PubMed Central, NCBI Bookshelf, Cochrane Library, clinicaltrials.gov, National G...
Sinonasal carcinomas are rare and account for 3% of all malignant tumours of head and neck. Squamous cell carcinoma is the commonest histological variant. We present a case of sinonasal squamous cell carcinoma in a 52-years-male and another rare case of intestinal type sinonasal adenocarcinoma in 50-years-male.
OBJECTIVES/HYPOTHESIS Removal of the medial orbital wall for sinonasal tumor involvement is required to obtain complete oncologic resection. However, orbital fat herniation can produce significant morbidity, including enophthalmos and diplopia. The purpose of the current study was to evaluate outcomes following use of porcine small intestine submucosa (SIS) grafts for orbital reconstruction fol...
