Previously, a computer-based navigation system has not been used routinely for en-bloc resection of sacral tumors. In order to improve the accuracy of tumor resection, O-arm navigation was used to join anterior and posterior osteotomies during an en-bloc resection of a sacral Ewing's sarcoma. This case study describes the technique for en-bloc resection of a sacral Ewing's sarcoma guided by O-a...

BACKGROUND Invasion of the chest wall per se is not a contraindication for tumor resection in non-small cell lung cancer (NSCLC), provided there is no mediastinal lymph node or vital structure involvement. Although widely known to Brazilian surgeons, the 'resection in bird cage' technique has never been widely studied in terms of patient survival. Thus, the objective of this study was to evalua...

UNLABELLED Giant cell tumour in the metatarsal of a skeletally immature person is uncommon. Adequate surgical resection in this region can be difficult to achieve as there is little space between the rays of the foot. Furthermore, there is the challenge of restoring the metatarsophalangeal articulation after resection of the tumor. We describe a technique using non-vascularised fibular graft fo...

Objectives. Endoscopic submucosal dissection (ESD) is a promising technique to treat early colorectal neoplasms by facilitating en bloc resection without size limitations. Although ESD for early gastrointestinal epithelial neoplasms has been popular in Japan, clinical experience with colorectal ESD has been rarely reported in Taiwan. Methods. From March 2006 to December 2011, 92 consecutive pat...

OBJECTIVES/HYPOTHESIS The aim of this study was to present our experience with management of malignant lesions arising within the masticator space, and to describe a technique of en bloc resection and reconstruction. STUDY DESIGN Case series and case report. METHODS Eight cases of masticator space malignancies treated surgically with en bloc resection and free flap reconstruction were retro...

five cases of giant cell tumor of the lower end of radius are reported. three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years. en bloc resection followed by reconstructive procedures were performed in three of the cases with good results.

BACKGROUND The purpose of this retrospective analysis was to evaluate ocular function and survival rates among treatment modalities in patients with maxillary sinus cancer with orbital invasion. METHODS Eighty-seven patients were classified according to the main treatment modality. Ocular function preservation rates and survival rates were evaluated for each therapeutic modality. RESULTS Th...

benign fibrous histiocytoma is a rare tumor of nose and paranasal sinuses that originates from histiocytes. ‎‎the main symptoms of patients are nasal obstruction and nasal mass. ‎our patient was presented with chief complaints of nasal obstruction and rhinorrhea non responsive to antibiotic treatment. in computed tomography scan a giant mass in left maxillary sinus and ipsilateral nasal cavity ...

BACKGROUND The objective of this study was to evaluate the efficacy and safety of minimally invasive transoral en bloc resection of superficial pharyngeal and laryngeal cancers. METHODS Forty-one superficial lesions (from 35 patients) were resected transorally under a surgical microscope using a monopolar cautery. Quality of life (QOL) was assessed using a questionnaire European Organization ...

The surgical treatment of fibrous dysplasia remains a challenge for the pediatric orthopedist because of its high recurrence rate. Although a few successful treatments have been reported by using en bloc resection and bone graft in adults, this has not been reproduced in children. In this report, the authors present two children (2.5 and 6 years old) with monostotic expansile fibrous dysplasia ...
