BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) has been growing in popularity for the treatment of lumbar disc herniation (LDH) due to its irreplaceable advantages over conventional open surgery. Compared with common lumbar disc herniations, discectomy of highly migrated LDH by PELD is known to be very difficult. Highly migrated lumbar disc herniation has long been a challenge for its specific characteristics. Three approaches for PELD have been applied to access a highly migrated LDH, including an interlaminar approach (IL), transforaminal approach (TF), and contralateral transforaminal approach (CTF)...

BACKGROUND: Delivery of therapeutic agents directly through the round window (RW) offers promise for treating sensorineural hearing loss. However, hearing loss can result from the surgical approach itself, and the reasons for this are poorly understood. We examined the hearing loss following the 3 major steps involved with the RW approach to access the mouse cochlea: bullostomy, RW puncture, and RW injection. METHODS: Twenty-one adult CBA/J mice underwent bullostomy alone, 10 underwent RW puncture, and 8 underwent RW injection with PBS with 5% glycerol...

Endoscopic full-thickness resection (EFTR) is a procedure that makes it possible to access the lesions that are on the wall of the digestive tract via the shortest distance through the mouth. Because of the ultra-minimal invasive nature of the treatment, pure EFTR is a highly promising surgical procedure that allows the radical excision of full-thickness layers of digestive tract tumors using only a flexible endoscope. There are 2 types of EFTR methods: exposed and non-exposed. Considering the risks of contracting infection and intraperitoneal dissemination of tumor cells, non-exposed EFTR is an ideal method...

Transoral robotic surgery (TORS) is a technique used to treat oral, throat, and skull base cancers using a minimally invasive robotic approach through the mouth and throat. The TORS procedure allows deeper access and dissection of suspicious lesions and neoplastic growths in the oral cavity and those that extend from the throat to the base of the skull. Robotic surgery allows the surgeon to operate in tight spaces without a large open incision. This article discusses symptoms and risk factors of oral, throat, and skull base cancers; types of procedures that can be performed using the TORS approach; specialized instrumentation; patient selection; surgical advantages and disadvantages; patient benefits; and the role of the surgical team in preparing to intraoperatively care for the TORS patient...

BACKGROUND: Despite the development of functional endoscopic endonasal surgery, there are still areas of the maxillary sinus that remain technically difficult to access using a standard middle meatal antrostomy as well as deep-seated skull base lesions requiring expanded transmaxillary approaches. METHODS: All patients who underwent transnasal endoscopic partial maxillectomy (TEPM) in a single institution from 2000 to 2014 were retrospectively reviewed. The TEPM was classified into 5 types according to the anatomic structures progressively removed and to the access provided...

BACKGROUND: Less downtime following esthetic interventions leads to the popularity of injectable solutions for facial rejuvenation treatments. Surgical interventions for esthetic purposes are usually associated with higher complication rates and longer recovery times when compared to less invasive treatments. Here we present for the first time a minimally invasive surgical technique for a simultaneous mid-face and eyebrow lift using one small temporal incision. MATERIALS AND METHODS: We prospectively studied patients who underwent facial rejuvenation using a minimal undermining suspension technique (MUST) in an outpatient setting...

BACKGROUND: Facial fractures may lead to sequelae due to the trauma but also as a result of surgery. Complications to lower eyelid incisions include ectropion, scleral show, entropion, canthal malposition, and lid edema. The aim of this study was to compare the occurrence of such complications depending on whether a subciliary or transconjunctival incision was used for surgical access. METHODS: All consecutive patients surgically treated for a facial fracture between June 2005 and December 2012 with a lower eyelid incision and a minimal follow-up of 6 months were included in this retrospective study...

: Laparoscopic cholecystectomy has almost replaced the age-old procedure of open cholecystectomy for gall stone disease. Further attempts are made to reduce the number of ports to give maximum benefits of minimally invasive surgery. The author has developed a technique where 10-mm port in supraumbilical area and 5-mm port in epigastric area are used and hence the nomenclature of single and a half incision laparoscopic cholecystectomy. It is different from two-port laparoscopic cholecystectomy where the second port is 10 mm...

BACKGROUND: Surgery for low rectal cancer remains a challenge when a standard laparoscopic approach is used. Transanal endoscopic total mesorectal excision (TME) has been shown to be feasible and to be associated with a low conversion rate. Combining the transanal and transabdominal single-port approaches (with an abdominal single port implanted in the future stoma and extraction site) could allow TME with minimal wound trauma, low morbidity, and faster recovery. The aim of the current study was to assess the short- and mid-term results of this technique...
