BACKGROUND: Cystic hygroma is a rare benign abnormality of the lymphatic system generally occurring in young children less than 2 years old. The standard transcervical surgical treatment of cystic hygroma may often leave a permanent scar in the neck region. CASE PRESENTATION: We report a case of cystic hygroma in a 19-month-old Asian baby girl successfully treated with robot-assisted excision through a hairline neck-lift approach. We present the use of the Yang's retractor as an instrumental advancement to this surgical approach...

BACKGROUND: Cervical approaches to the dens are limited by the presence of several structures, including the spinal cord, vertebral arteries, C1 articular pillars, and C2 nerves. Surgical approaches to access the high anterior cervical spine classically encompass the extended anterior retropharyngeal route, transoral route, and extreme lateral route, each of which has its own pattern of morbidity or complications. Percutaneous procedures to drain infections in this area have a limited yield...

AIMS: To test the hypothesis that prolonged jaw opening, as can occur during routine dental procedures, increases nociceptive sensitivity of the masseter muscle and increases cytokine expression. METHODS: Sprague-Dawley rats were used to investigate behavioral and cellular changes in response to prolonged jaw opening. A surgical retractor was placed around the maxillary and mandibular incisors, and the jaw was held at near maximal opening for 20 minutes. Head-withdrawal responses to mechanical stimuli applied to the facial skin overlying the left and right masseter muscles were determined following jaw opening...

BACKGROUND/AIMS: The study aims to prevent serious urologic injury during a radical hysterectomy; we propose that one of the most important procedural steps is the careful management of the vesicouterine ligament (VUL). PATIENTS AND METHODS: Between January 2013 and October 2014, we used a novel internal retractor in 17 patients undergoing a laparoscopic radical hysterectomy (LRH) for early-stage cervical cancer to obtain and secure a better surgical view. For management of the VUL during the laparoscopic procedure, we routinely used an internal retractor (EndoGrab; Virtual Ports, Misgav, Israel) and vessel tape to reposition the ureter in a safe lateral-caudal direction...

STUDY DESIGN: A cadaveric study. OBJECTIVE: To investigate possible variations of posterior pharyngoesophageal (PE) wall thickness in the horizontal plane and their implications for anterior spine surgery. SUMMARY OF BACKGROUND DATA: Lower cervical levels (C5-7) are most commonly involved in cases of PE injury, and PE wall thickness could be one of the proposed reasons for the high incidence of PE injuries at these levels. The purpose of this study was to document thickness variations of the posterior PE wall at different cervical spine levels, because the study could provide valuable anatomical information that could reduce iatrogenic injuries caused by retractors or instrumentation...

INTRODUCTION: Mediastinal goiter is a benign disease, which is defined as a goiter with the greater portion of its mass lying below the thoracic inlet. It is controversial whether the cervical approach is the best approach for all mediastinal goiter surgeries. CASE PRESENTATION: A 71-year-old woman presented with respiratory discomfort during exertion. Computed tomography (CT) revealed a mediastinal goiter extending to the arch of the aorta. Surgical resection was performed using a clavicle-lifting technique...

The minimally invasive posterior cervical foraminotomy procedure has become a common and successful procedure for the treatment of cervical radiculopathy. Specifically, the minimally invasive approach allows for decreased postoperative pain, blood loss, and length of hospitalization by preserving the surrounding soft tissue as compared with the traditional open approach. This article and accompanying video demonstrates the technique for a primary, single-level minimally invasive posterior cervical foraminotomy as performed through a tubular retractor...

BACKGROUND: Minimally invasive surgery has expanded over the past two decades and was initially used for the treatment of lumbar disc herniation. Later, this approach was used to treat other spine pathologies, as well as to perform spinal fusion and extended spinal decompression. In this study, we report our experience regarding the use of a minimal surgical approach in the treatment of intradural extramedullary spinal cord tumours. METHODS: Between January 2008 and July 2013, 18 patients with an intradural extramedullary tumour were included in the study (13 thoracic, 4 lumbar and one cervical tumours)...

STUDY DESIGN: Retrospective chart review. PURPOSE: A comparison of mini open foraminotomy (MOF) for cervical radiculopathy using either large tubular (LT) or TrimLine (TL) retractors. OVERVIEW OF LITERATURE: Posterior foraminotomy relieves compression of the cervical nerve root in radiculopathy patients. However, invasion of the paravertebral muscle may cause major problems in these patients. To address these problems, we performed MOF. METHODS: Twenty cervical radiculopathy patients (16 male and 4 female) who underwent MOF between May 2004 and August 2011 were assigned to LT and TL groups...

INTRODUCTION: A microsurgical anterior cervical approach with discectomy and fusion (MACDF) is one of the most widely used procedures for treating radicular disorders. This approach is highly successful; however, it is not free from complications. These can be associated with soft tissue injuries. AIM OF THE STUDY: The recognition of the risks for these complications should be identified for timely prevention and safe treatment. MATERIALS AND METHODS: HASH(0x4a99c78) STUDY DESIGN: Retrospective case control study...

BACKGROUND: Minimally invasive spine (MIS) techniques have been available for many years, but their application has been largely limited to degenerative spine diseases. There are few reports in the literature of using MIS techniques for removal of neoplasms. We report our experience using a modified MIS technique for removal of an occipital-cervical junction (OCJ) schwannoma with attention to technical aspects of this approach. CASE DESCRIPTION: A 64-year-old male presented with several months of neck pain radiating to the shoulder with bilateral hand numbness...
