Surgical Treatment of Maxillary Antrum Neoplasms

Journal of Craniofacial Surgery, 2018
Abstract Paranasal sinus cancers comprise about 0.3% of all cancers and 80% of these lesions arise in the maxillary sinus. A masquerading primary sinus tumour represents a therapeutic challenge as most patients with maxillary antrum cancer are diagnosed with advanced disease. However, distant metastases rarely occur.

Oncocytic carcinoma of the maxillary sinus: a rare neoplasm

European Archives of Oto-Rhino-Laryngology, 2006
Oncocytic neoplasms are tumors composed of oncocytes (i.e., epithelial cells with a large cytoplasm that is rich in mitochondria). Most cases are benign and originate from the major salivary glands, while the minor salivary glands are rarely involved. Occurrence of oncocytic carcinoma (or malignant oncocytoma) within the sinonasal tract is an unusual ...

Maxillary osteoplastic flap technique for the treatment of pediatric pterygopalatine fossa neoplasms

International Journal of Pediatric Otorhinolaryngology, 2006
Pterygoid fossa neoplasms in children are rare. Management of these neoplasms has been challenging because of tumor vascularity, difficult surgical access and complex anatomy from which these tumors arise. Surgical approach depends upon tumor extension and ability to obtain adequate exposure for successful tumor excision.

Ameloblastomas are benign tumors derived from the odontogenic apparatus. Of these tumors, 80% originate in the mandible, while 20% originate in the maxilla. Six cases of maxillary ameloblastoma treated at the UCLA hospitals are presented; four of these cases showed extensive and destructive tumor growth involving vital structures, including the orbit ...

NEOPLASMS OF BOTH MAXILLARY SINUSES

Archives of Otolaryngology - Head and Neck Surgery, 1945
Because of the apparent rarity of this case in which both maxillary antrums were invaded by neoplasm, a careful scrutiny of the literature was undertaken in order to determine whether any such case had been previously reported. During the past twenty years there has been no report of a case of bilateral neoplastic involvement of the antrums.
