Pain is one of the most common symptoms among cancer patients, and particularly in those who suffer from metastatic or terminal disease. There is great importance in delivering good pain management to these patients in order to alleviate their suffering, improve their functional status and their overall quality of life. In most cases, pain management is based on pharmacotherapy with opioids and other medications. However, there are selected patients for whom pharmacotherapy does not achieve acceptable pain relief or is associated with marked side effects...

OBJECTIVE: The objective of this study was to provide a theoretical basis for the selection of optimal surgical procedures in ex vivo simulated bilateral vocal fold paralysis (BVFP). STUDY DESIGN: Four surgical stages were sequentially performed on 10 excised canine larynges with simulated BVFP: (1) transverse cordotomy, (2) medial arytenoidectomy, (3) subtotal arytenoidectomy, and (4) total arytenoidectomy. MATERIALS AND METHODS: The sound pressure level, the signal-to-noise ratio, the glottal resistance, the glottal airflow (GF), the maximal glottal area (MGA), and spectrograms were measured after each stage...

BACKGROUND: Pain is often one of the most debilitating symptoms in patients with advanced oncological disease. Patients with localized pain due to malignancy refractory to medical treatment can benefit from selective percutaneous cordotomy that disconnects the ascending pain fibers in the spinothalamic tract. OBJECTIVES: Over the past year, we have been performing percutaneous radiofrequency cordotomy with the use of the O-Arm intraoperative imaging system that allows both 2D fluoroscopy and 3D reconstructed computerized tomography imaging...

Importance: Bilateral vocal fold immobility (BVFI) can result in considerable voice and airway impairment. Although the carbon dioxide (CO2) laser is commonly used in transverse cordotomy, the coblator, a minimally invasive, low-thermal technology, has been increasingly used in otolaryngology. Objective: To investigate outcomes associated with coblation to treat BVFI. Design, Setting, and Participants: A retrospective case series was conducted between January 2012 and June 2017 including 19 patients with BVFI who underwent cordotomy by coblation in a single tertiary care institution...

BACKGROUND: Image-guided surgery techniques in spinal surgery are usually based upon fluoroscopy or computed tomography (CT) scan, which allow for a real-time navigation of bony structures, though not of neural structures and soft tissue remains. OBJECTIVE: To verify the effectiveness and efficacy of a novel technique of imaging merging between preoperative magnetic resonance imaging (MRI) and intraoperative CT scan during removal of intramedullary lesions. METHODS: Ten consecutive patients were treated for intramedullary lesions using a navigation system aid...

The purpose of this study is to demonstrate the potential of diffusion tensor imaging (DTI) to reveal structural mechanisms underlying spinal ablative procedures, including percutaneous radiofrequency cordotomy (PRFC). PRFC is a surgical procedure that produces analgesia through focal ablation of the lateral spinothalamic tract (STT), thereby interrupting the flow of pain information from the periphery to the brain. To date, studies regarding mechanisms of analgesia after PRFC have been limited to postmortem cadaveric dissection and histology...

Cancer pain management is comprehensive, and it generally begins with pharmacotherapy in a step-wise approach per analgesic guidelines established decades ago by the World Health Organization. This analgesic ladder involves the prescribing of co-analgesics, adjuvants, and opioids, with each step depending on pain severity. Although the majority of cancer pain responds to this strategy, there exist patients who do not respond adequately or experience significant side effects or intolerance to pain medications...

Open anterolateral cordotomy is an effective treatment option for adults with intractable pain, but it has seldom been attempted in children. In the 2 previously reported cases in children, the procedure was used within 10 days of death from neoplastic disease. In this paper the authors describe 2 cases in which open cordotomy was used successfully in children outside the immediate terminal phase of disease. Both patients experienced effective analgesia with minimal adverse effects. The authors propose that consideration of cordotomy as an option for the management of intractable pain in children does not need to be delayed until death is imminent...

REVIEW
Yike Li, Gaelyn Garrett, David Zealear
Vocal fold paralysis (VFP) refers to neurological causes of reduced or absent movement of one or both vocal folds. Bilateral VFP (BVFP) is characterized by inspiratory dyspnea due to narrowing of the airway at the glottic level with both vocal folds assuming a paramedian position. The primary objective of intervention for BVFP is to relieve patients' dyspnea. Common clinical options for management include tracheostomy, arytenoidectomy and cordotomy. Other options that have been used with varying success include reinnervation techniques and botulinum toxin (Botox) injections into the vocal fold adductors...

OBJECTIVE: To report the use of flexible fiber CO2 laser in the endoscopic management of pediatric airway cases. METHODS: A retrospective review was conducted of patients who underwent CO2 laser-assisted airway procedures between September 2007 and January 2014 at a tertiary pediatric hospital. RESULTS: Sixty-eight patients underwent 80 procedures utilizing flexible fiber CO2 laser. Procedures included supraglottoplasty (n = 32), laryngeal cleft repair (type I [n = 10], type II [n = 7], type III [n = 6]), suprastomal granuloma excision (n = 6), cordotomy (n = 4), laryngeal neurofibroma excision (n = 4), laryngeal granulomatous mass excision (n = 1), subglottic stenosis excision (n = 6), division of glottic web (n = 2), subglottic cyst excision (n = 1), and supraglottic biopsy (n = 1)...

BACKGROUND AND PURPOSE: There are limited data on the use of postoperative imaging to evaluate the cordotomy lesion. We aimed to describe the cordotomy lesion by using postoperative MR imaging in patients after percutaneous cordotomy for intractable cancer pain. MATERIALS AND METHODS: Postoperative MR imaging and clinical outcomes were prospectively obtained for 10 patients after percutaneous cordotomy for intractable cancer pain. Area, signal intensity, and location of the lesion were recorded...

BACKGROUND: Up to 20% of patients experience only partial pain relief after percutaneous cordotomy for cancer pain. OBJECTIVE: To determine whether diffusion tensor imaging (DTI) can quantify neural ablation and help evaluate early postoperative outcomes after cordotomy. METHODS: Patients undergoing percutaneous CT-guided cordotomy for intractable cancer pain were prospectively studied. Pre- and postoperative assessment was made using the visual analog scale (VAS) on pain and the pain severity scores of the Brief Pain Inventory Short Form...

Palliative cervical cordotomy can be performed via percutaneous radiofrequency ablation of the lateral C1-2 spinothalamic tract. This rare procedure can be safe, effective, and advantageous in mitigating medically intractable unilateral extremity pain for selected patients with end-stage cancer. This report reviews the indications, techniques, risks, and potential benefits of cordotomy. We describe our recent experience treating 3 patients with CT-guided C1-2 cordotomy and provide the first characterization of spinal cord diffusion MR imaging changes associated with successful cordotomy...

OBJECTIVES/HYPOTHESIS: Endoscopic management of bilateral vocal fold paralysis (BVFP) includes cordotomy and arytenoidectomy, and has become a well-accepted alternative to tracheostomy. However, the costs and quality-of-life benefits of endoscopic management have not been examined with formal economic analysis. This study undertakes a cost-effectiveness analysis of tracheostomy versus endoscopic management of BVFP. STUDY DESIGN: Cost-effectiveness analysis. METHODS: A literature review identified a range of costs and outcomes associated with surgical options for BVFP...
