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...

OBJECTIVE To explore the feasibility, safety, efficacy, and cosmetic outcomes of transvaginal endoscopic salpingectomy for tubal ectopic pregnancy. METHODS From May 2009 to May 2012, we prospectively enrolled 40 patients, each of whom had been scheduled for a salpingectomy because of a tubal ectopic pregnancy, and randomized them into two groups: transvaginal endoscopic surgery and laparoscop...

A modified approach to endoscopic carpal tunnel release has been developed and tested in 60 cadaveric specimens by three surgeons using the Agee endoscopic carpal tunnel release system. The modified approach, which includes specific localization of the hook of the hamate, flexor retinaculum, and the superficial palmar arch utilizing topographical landmarks, avoids entry into Guyon's canal and i...

OBJECTIVES We evaluated the current status of endoscopic thyroidectomy procedures in Korea in terms of indications, contraindications, advantages, disadvantages, complications, and limitations of each approach. METHODS An email survey, consisting of 15 questions, was sent to 29 experienced endoscopic thyroidectomy surgeons. RESULTS The most commonly used approach was the gasless transaxilla...

OBJECTIVES We sought to determine the value of preoperative staging by magnetic resonance imaging (MRI) assessment in the surgical management of sinonasal inverted papillomas (IPs). METHODS Preoperative MRI staging was used to assess 22 patients with IPs. In addition to the Krouse staging system, T3 cases were categorized as subgroup T3-B if tumors extended into the frontal sinus or the supra...
