The aim of this report was to summarize our preliminary experience on the resection of tumors located in Meckel's cave via the endoscopic endonasal transmaxillary transpterygoid approach with image-guided system and to investigate the feasibility and efficacy of this approach. Two patients who had tumors in left Meckel's cave underwent surgical treatment using the image-guided endoscopic endona...

one of the routine methods for diagnosis and treatment of cholelithiasis is endoscopic retrograde cholangiopancreatography. it is an effective method but is associated with some complications (9.8%) which the most common is pancreatitis (5.4%). one of the rare complications is basket impaction in the common bile duct which is treated with different methods. a 58 years male history of laparoscop...

PURPOSE The aim of this work is to study the use of this technique in extirpation of malignant tumors of the maxillary sinus. This includes the exposure for adequate tumor resection and the preservation of as much as possible functional tissue integrity. This approach will be evaluated including the advantages and disadvantages as regards the physiological function, aesthetic outcome and the co...

This report describes a new, minimally invasive procedure, posterior percutaneous endoscopic cervical diskectomy, performed with a unilateral biportal endoscopic approach. The procedure is used to treat cervical foraminal soft disk protrusion. This report also describes the short-term results with this procedure. In 2015, 14 patients underwent this new, minimally invasive procedure. The techniq...

BACKGROUND Based on our previous experiences with endoscopic or robotic neck surgery utilizing the retroauricular (RA) or modified facelift (MFL) approach, we realized the value of verifying the feasibility of endoscopic supraomohyoid neck dissection (SOND). Therefore, the purpose of this study was to evaluate the potential role of endoscopic SOND. METHODS Six patients who underwent elective ...

Endoscopic ultrasound-guided pancreatic duct intervention (EUS-PDI) is an emerging endoscopic approach allowing access and intervention to the pancreatic duct (PD) for patients with failed endoscopic retrograde pancreatography (ERP) or patients with surgically altered anatomy. As opposed to biliary drainage for which percutaneous drainage is an alternative following failed endoscopic retrograde...

OBJECTIVE To describe an endoscopic transnasal approach to the pterygopalatine fossa (PPF). DESIGN Case series of 3 patients. SETTING An academic medical center. Patients One patient presented with an asymptomatic PPF schwannoma. The second patient presented after a sudden onset of complete unilateral vision loss with a complete ipsilateral sphenoid sinus opacification and radiographic sign...

BACKGROUND Direct comparisons of microscopic and endoscopic resection of sellar lesions are scarce, with conflicting reports of cost and clinical outcome advantages. OBJECTIVE To determine if the proposed benefits of endoscopic resection are realized on a population level. METHODS We performed a matched cohort study of 9,670 adult patients in the MarketScan database who underwent either end...

OBJECTIVES Endoscopic approach provides excellent magnification and visualization, and a purely transnasal approach is minimally invasive method. However, it is very difficult to repair anterior and lateral fractures with the previous transnasal endoscopic approaches, since repair of orbital fractures is managed through the middle meatus and ostium from the posterior side of the nasolacrimal du...

OBJECTIVES The central location and complex neurovascular structures of the posterior cranial fossa make tumor resection in this region challenging. The traditional surgical approach is a suboccipital craniotomy using a microscope for visualization. This approach necessitates a large surgical window and cerebellar retraction, which can result in patient morbidity. With the advances in endoscopi...
