Modified transnanal endoscopic maxillectomy: a novel surgery style of maxillary malignant tumor

Background: Over the past decade, the indications of endoscopic surgery had been applied to the selected cases of malignant tumors. The acceptable morbidity and outcomes suggested that this technique could be available for the management of sinonasal malignant tumors. Objectives: To present our initial experience with the novel technique, modified transitional endoscopic maxillary, improve method of surgery for maxillary malignant tumor. Clinical and radio-anatomic imagery would be presented to describe and define this novel technique. Methods: Surgical patients with carcinoma of nasal cavity, ethmoid sinus and maxillary sinus treated from October 2008 to May 2012 were reviewed. Ten patients underwent transmogrification endoscopic maxillectomy. Describing clinic and radioanatomic analysis of preand post-endoscopic maxillectomy. Results: Ten patients had surgical treatment of nasal cavity, ethmoid sinus and maxillary sinus lesions. Modify transnasal endoscopic maxillectomy was utilized in six cases. Complete resection was achieved in six patients. Follow-up of patients alive was 12-36 months, the survival was 100%. One case was recurrent in 1 year post-operation; Open surgery was applied to resect the tumor and the remnant maxillary bone. Conclusions: Clinical and radioanatomic imagery demonstrated a significantly improvement in access to nasal cavity, ethmoid sinus and maxillary sinus. Modified transnasal endoscopic maxillectomy was a novel surgery style aimed to nasal malignant tumors.
