Cordotomy

OBJECTIVES: To determine the decannulation rate (DR) and revision surgery rate after surgery for bilateral vocal fold paralysis (BVFP). DATA SOURCES: Five databases (MEDLINE, PubMed, Embase, Web of Science, Scopus) were searched for the period 1908-2020. METHODS: The systematic literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were pooled using a random-mixed-effects model...

OBJECTIVE: To compare two surgical techniques, the Wendler glottoplasty (GP) and its modification, the vocal fold shortening, and retrodisplacement of the anterior commissure (VFSRAC) associated with laser assisted voice adjustment (LAVA) cordotomy, used to feminize the voice of transgender women by increasing the fundamental frequency (F0 ). METHODS: A retrospective study of 22 trans-women (20-62 years-old) was carried out. 12 of them were treated with GP and 10 with the VFSRAC+LAVA technique...

PURPOSE: The aim of this study is to evaluate functional outcomes in terms of decannulation rate and quality of life of patients affected by PGS (Grades I-IV) treated only by transoral CO2 laser microsurgery (TOLMS) in two tertiary centers. METHODS: An observational retrospective study was carried out, enrolling 22 patients affected by PGS who were treated by a transoral approach at two tertiary referral centers. Surgical treatment included TOLMS with tailored laser resection of the scar tissue combined with posterior cordotomy, resurfacing of the raw area with mucosal microflap, or placement of a Montgomery T-tube or Keel stent...

This article reviews the current evidence of interventional radiology procedures for patients suffering with debilitating cancer pain, refractory to conventional therapies. Cancer pain is notoriously difficult to treat. Up to 90% of cancer patients experience pain with 56-82% of cancer pain controlled inadequately. Cancer pain influences a patient's ability to perform normal daily activities, causes higher risk of depression, and reduces quality of life. Pain-free status has been universally voted as a "good death"...

Traditional medical neuroanatomy/neurobiology textbooks teach that pain is generated by several ascending pathways that course in the anterolateral quadrant of the spinal cord, including the spinothalamic, spinoreticular and spinoparabrachial tracts. The textbooks also teach, building upon the mid-19th century report of Brown-Séquard, that unilateral cordotomy, namely section of the anterolateral quadrant, leads to contralateral loss of pain (and temperature). In many respects, however, this simple relationship has not held up...

Although ablation has a limited role in the management of chronic noncancer pain, ablation continues to help patients with treatment of refractory cancer-related pain. Interdisciplinary treatment involving supportive care, pain medicine, oncology, and neurosurgery is critical to optimizing the timing and outcome of neurosurgical ablative options for pain management. In this review, 3 targets for ablative surgery-the spinothalamic tract, the dorsal column's visceral pain pathway, and the anterior cingulate cortex-are discussed with a focus on patient selection and key aspects of surgical technique...

BACKGROUND: The American Board of Plastic Surgery collects data on 20 common plastic surgery operations as part of the Continuous Certification process. The goal of this study was to describe clinical trends in Dupuytren contracture repair since 2008 as they relate to evidence-based medicine articles published in this timeframe. METHODS: Cumulative tracer data for Dupuytren contracture were reviewed for the period from February of 2008 to March of 2020 and compared with evidence-based medicine articles published in Plastic and Reconstructive Surgery ...

INTRODUCTION: Bilateral vocal cord immobility (BVCI) is a leading cause of stridor and airway obstruction in neonates which may arise idiopathically, as a result of birth trauma, or in the setting of Central nervous system lesions such as Arnold-Chiari malformation. Although many children with BVCI may be managed conservatively, surgical intervention may be necessary in those patients with ongoing upper airway obstruction. Many interventions have been described including, tracheostomy, cordotomy, cricoid splitting procedures, and arytenoidectomy...

BACKGROUND: Percutaneous cervical cordotomy (PCC), which selectively interrupts ascending nociceptive pathways in the spinal cord, can mitigate severe refractory cancer pain. It has an impressive success rate, with most patients emerging pain-free. Aside from the usual complications of neurosurgical procedures, the risks of PCC include development of contralateral pain, which is less understood. OBJECTIVE: To evaluate whether sensory and pain sensitivity, as measured by quantitative sensory testing (QST), are associated with PCC clinical outcomes...

OBJECTIVES: Transoral laser surgery for glottic stenosis (transverse cordotomy and anteromedial arytenoidectomy (TCAMA)) is often complicated by granulation tissue (GT) formation. GT can cause dyspnea and may require surgical removal to alleviate airway obstruction. Inhaled corticosteroids (ICS) have been shown to reduce benign vocal fold granulomas, however its use to prevent GT formation has not been described. We aimed to analyze the effect of immediate postoperative ICS on GT formation in patients undergoing transoral laser surgery for glottic stenosis...

BACKGROUND: A prospective randomized study was conducted on 40 patients with true bilateral vocal fold abductor paralysis. The patients under the study were divided into 2 groups, group (A) including 20 patients who underwent laser posterior cordotomy and another group (B) including 20 patients who underwent combined laser posterior cordotomy with suture lateralization, the patients under the study presented at otorhinolaryngology outpatient clinic at faculty of medicine, Cairo University...

The aim of this study is to analyse outcome of patients with bilateral abductor palsy undergoing unilateral partial arytenoidectomy and unilateral posterior cordotomy in terms of respiration, phonation and risk of aspiration. Initially tracheostomy was only treatment available to relieve respiratory distress. Now various methods are described e.g. endoscopic posterior cordotomy, arytenoidectomy, suture lateralization of vocal cords, laryngeal reinnervation and muscle transfer procedures. In our study, review of management of 21 cases of bilateral abductor palsy were carried out...

Pain is a common source of suffering for seriously ill patients. Typical first-line treatments consist of lifestyle modifications and medication therapy, including opioids. However, medical treatments often fail or are associated with limiting systemic toxicities, and more targeted interventional approaches are necessary. Herein, we present options for minimally invasive techniques for the alleviation of pain in palliative patients from a head-to-toe approach, with a focus on emerging therapies and advanced techniques...

A 75-year-old man presented to our Interventional Cancer Pain service for consideration of a percutaneous cervical cordotomy (PCC) to control severe chest wall pain secondary to malignant mesothelioma. His medical history included a neuroinflammatory disorder, neuromyelitis optica, for which he had previously had a prolonged hospital admission, with ongoing neurological deficit. Little information is available regarding the safety of PCC in a patient with this condition, specifically the risk of neurological relapse, and we were initially wary about going ahead...

Stereotactic and functional neurosurgery(SFN)is one of the oldest subspecialties of neurosurgery. In Japan, functional epilepsy surgery was performed in the Meiji era, even before World War II, when general surgeons used to operate on patients with intractable cancer pain through open myelotomy or cordotomy. Knowledge gathered from such age-old procedures provided the basic understanding of neurophysiology and hence, functional neurosurgery used to be termed as "applied neurophysiology". Human stereotactic surgery was introduced in 1947 and many Japanese neurosurgeons, particularly Hirotaro Narabayashi, Keiji Sano and Chihiro Ohye, contributed to the development of this field...

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: Although intramedullary astrocytoma is associated with a high mortality rate, the optimal treatment has not reached a consensus. This study aimed at evaluating neurologic function and overall survival rate (OSR) in the treatment of this tumor. SETTING: The single institution in Japan. METHODS: This study enrolled 67 subjects who underwent surgical treatment for intramedullary astrocytoma...

OBJECTIVES: Bilateral adductor vocal cord paralysis (BAVCP) is a rare and challenging condition whose main consequence is reduction of airway patency at the glottic level, often causing respiratory distress, while vocal function tends to remain almost normal. We investigated the effect of transoral glottal widening on quality of life and decannulation rates in patients affected by BAVCP. METHODS: We retrospectively evaluated patients affected by BAVCP and treated by transoral CO2 posterior cordotomy with or without medial partial arytenoidectomy (PC ± MPA) at two referral centers...

PURPOSE OF REVIEW: Present the state-of-the-art overview of laryngeal pacing for treatment of bilateral vocal fold paralysis. A minimally invasive unilateral pacing system and a fully implantable bilateral pacing system are currently in clinical trials. The relative advantages and disadvantages of each are discussed. RECENT FINDINGS: Research in functional electrical stimulation for the reanimation of the posterior cricoarytenoid muscle has successfully translated from animal models to human clinical trials for unilateral pacing and bilateral pacing...

BACKGROUND AND PURPOSE: Percutaneous cervical cordotomy offers relief of unilateral intractable oncologic pain. We aimed to find anatomic and postoperative imaging features that may correlate with clinical outcomes, including pain relief and postoperative contralateral pain. MATERIALS AND METHODS: We prospectively followed 15 patients with cancer who underwent cervical cordotomy for intractable pain during 2018 and 2019 and underwent preoperative and up to 1-month postoperative cervical MR imaging...

OBJECTIVES/HYPOTHESIS: Glottic stenosis is a discrete cause of airway compromise. We aimed to determine the surgical outcomes of transverse cordotomy with anteromedial arytenoidectomy (TCAMA), performed in the setting of isolated glottic stenosis resulting from two discrete etiologies: bilateral vocal fold paralysis (BVFP) and posterior glottic stenosis (PGS). STUDY DESIGN: Retrospective, analytic cohort study. METHODS: Twenty-six patients with isolated glottic stenosis were treated with TCAMA between 2006 and 2019...
