Atrophy of the posterior cricoarytenoid muscle as an indicator of recurrent laryngeal nerve palsy. (1/187)
BACKGROUND AND PURPOSE: The posterior cricoarytenoid (PCA) muscle is one of the intrinsic muscles of the larynx innervated by the recurrent laryngeal nerve. As such, recurrent laryngeal nerve palsy should not only result in paralysis of the true vocal cord or thyroarytenoid muscle but also in a similar change in the PCA muscle. The ability of CT and MR imaging to depict denervation atrophy in the PCA muscle in patients with recurrent laryngeal nerve palsy was evaluated. METHODS: Two investigators reviewed the CT and/or MR studies of 20 patients with a clinical history of vocal cord paralysis. The appearance of the PCA muscle was given a rating of 0, 1, 2, 3, or 4, with 0 being definitely normal and 4 being definitely abnormal or atrophic. Each study was also reviewed for the presence or absence of other features of vocal cord paralysis: thyroarytenoid muscle atrophy, anteromedial deviation of the arytenoid cartilage, an enlarged piriform sinus and laryngeal ventricle, and a paramedian cord. RESULTS: Atrophy of the PCA muscle was shown unequivocally in 65% of the cases and was most likely present in an additional 20%. The frequency with which other features of vocal cord paralysis were seen was as follows: thyroarytenoid atrophy, 95%; anteromedial deviation of the arytenoid cartilage, 70%; enlarged piriform sinus, 100%; enlarged laryngeal ventricle, 90%; and a paramedian cord, 100%. CONCLUSION: Atrophy of the PCA muscle may be commonly documented on CT and MR studies in patients with recurrent laryngeal nerve palsy and vocal cord paralysis, and therefore should be part of the constellation of imaging features of vocal cord paralysis. This finding is particularly useful when other imaging findings of vocal cord paralysis are absent or equivocal. (+info)Left recurrent laryngeal nerve palsy associated with silicosis. (2/187)
Left recurrent laryngeal nerve palsy usually results from invasion or compression of the nerve caused by diseases localized within the aortopulmonary window. This study reports the case of a 76-yr-old male with vocal cord paralysis due to lymph node involvement by silicosis. This rare entity was identified by video-mediastinoscopy, which revealed a granulomatous and fibrosed recurrent lymph node encasing the nerve. The nerve was dissected and released from scar tissues. Progressive clinical improvement was observed followed by total and durable recovery of the voice after 15 weeks follow-up. (+info)Recurrent laryngeal nerve palsy associated with mediastinal amyloidosis. (3/187)
Amyloidosis affecting peripheral nerves causing isolated nerve palsies is uncommon. Localised amyloidosis occurs less frequently than the reactive or immune related systemic forms, and mediastinal localisation is virtually unknown. We present a case of recurrent laryngeal nerve palsy associated with mediastinal AL amyloidosis in a middle aged man. (+info)A series of thyroplasty cases under general anaesthesia. (4/187)
Thyroplasty is an operation on the upper airway to improve voice quality in patients with unilateral vocal cord paralysis. It requires access to an uninstrumented larynx and a functional assessment of vocal cord medialization. It is a difficult anaesthetic procedure that requires sharing the airway with the surgeon. We describe an anaesthetic technique to give good operating conditions and a safe airway, using total intravenous anaesthesia, a laryngeal mask airway and intraoperative fibreoptic endoscopic assessment of the larynx, and present a series of 13 patients. Other anaesthetic techniques for thyroplasty are described and discussed. (+info)Left vocal cord paralysis associated with long-standing patent ductus arteriosus. (5/187)
SUMMARY: Left vocal cord paralysis in association with patent ductus arteriosus is unusual. We report a patient with long-standing patent ductus arteriosus (PDA) in whom CT studies obtained before and after paralysis developed showed an interval increase in size of the pulmonary trunk. The pathogenesis of left vocal cord paralysis in association with long-standing PDA is discussed. (+info)Outcomes and complications of thyroid surgery: retrospective study. (6/187)
OBJECTIVE: To study the outcome and complications of thyroid surgery. DESIGN: Retrospective study. SETTING: Regional hospital, Hong Kong. PATIENTS: Three hundred and twelve patients (266 women and 46 men) underwent thyroid surgery between January 1994 and December 1999. MAIN OUTCOME MEASURES: Complications of thyroidectomy for various thyroid diseases according to surgical technique used. RESULTS: Capsular dissection gradually became a more popular surgical technique: 33% and 58% in the first and second halves of the study period respectively (P<0.001). The overall rate of permanent vocal cord palsy was 2%. Near-total thyroidectomy became the preferred surgical treatment for toxic goitre over the study period. The incidence of recurrent hyperthyroidism was reduced from 21% to 7% (P>0.1, not significant). The incidence of hypoparathyroidism was approximately 30% after thyroidectomy for cancer. CONCLUSION: Capsular dissection is increasingly utilised in thyroid surgery. Low complication rates can be achieved after thyroidectomy for benign diseases. Hypoparathyroidism, however, is a relatively common complication after surgery for thyroid cancer. (+info)Cordotomy for bilateral cord abductal paralysis. (7/187)
OBJECTIVE: To investigate the clinical effects of cordotomy on bilateral cord abductal paralysis. METHODS: With unilateral cordotomy, we treated 4 patients with bilateral cord paralysis whose glottis size was about 2.0 mm to 2.5 mm. They were followed up for over one year. RESULTS: One week after surgery, the tracheotomy tubes of all 4 patients were plugged and no dyspnea occurred during rest and mild action. Their voices were more hoarse than before surgery. After 3 months, the tracheotomy tubes were successfully decannulated, and in the following one year, their respiration was normal and then speech was clear, although their voices were still a little hoarse. CONCLUSION: We suggest that cordotomy be one option in the treatment of bilateral cord abductal paralysis. (+info)Use of the laryngeal mask airway in thyroid and parathyroid surgery as an aid to the identification and preservation of the recurrent laryngeal nerves. (8/187)
A prospective study was carried out in patients undergoing thyroid and parathyroid surgery using a laryngeal mask airway (LMA) and electrical nerve stimulation to identify the recurrent laryngeal nerves. A total of 150 consecutive patients undergoing thyroid and parathyroid surgery by a single surgeon were assessed for suitability of anaesthesia via the LMA. Peroperatively, a fibre-optic laryngoscope was passed through the LMA to enable the anaesthetist to visualise the vocal cords while adduction of the cords was elicited by applying a nerve stimulator in the operative field. In all, 144 patients were selected for anaesthesia via the LMA. Fibre-optic laryngoscopy and nerve stimulation were performed in 64 patients (42.7%). The trachea was deviated in 51 (34.0%) and narrowed in 33 (22.0%). The recurrent laryngeal nerves were identified in all patients. There were no cases of vocal cord dysfunction resulting from surgery. The LMA can be safely used for thyroid and parathyroid surgery even in the presence of a deviated or narrowed trachea. It can assist in identification and preservation of the recurrent laryngeal nerve and is, therefore, of benefit to both patient and surgeon. (+info)Vocal cord paralysis is a medical condition characterized by the inability of one or both vocal cords to move or function properly due to nerve damage or disruption. The vocal cords are two bands of muscle located in the larynx (voice box) that vibrate to produce sound during speech, singing, and breathing. When the nerves that control the vocal cord movements are damaged or not functioning correctly, the vocal cords may become paralyzed or weakened, leading to voice changes, breathing difficulties, and other symptoms.
The causes of vocal cord paralysis can vary, including neurological disorders, trauma, tumors, surgery, or infections. The diagnosis typically involves a physical examination, including a laryngoscopy, to assess the movement and function of the vocal cords. Treatment options may include voice therapy, surgical procedures, or other interventions to improve voice quality and breathing functions.
Vocal cords, also known as vocal folds, are specialized bands of muscle, membrane, and connective tissue located within the larynx (voice box). They are essential for speech, singing, and other sounds produced by the human voice. The vocal cords vibrate when air from the lungs is passed through them, creating sound waves that vary in pitch and volume based on the tension, length, and mass of the vocal cords. These sound waves are then further modified by the resonance chambers of the throat, nose, and mouth to produce speech and other vocalizations.
The Recurrent Laryngeal Nerve (RLN) is a branch of the vagus nerve (cranial nerve X), which is a mixed sensory, motor, and autonomic nerve. The RLN has important functions in providing motor innervation to the intrinsic muscles of the larynx, except for the cricothyroid muscle, which is supplied by the external branch of the superior laryngeal nerve.
The recurrent laryngeal nerve supplies all the muscles that are responsible for adduction (bringing together) of the vocal cords, including the vocalis muscle, lateral cricoarytenoid, thyroarytenoid, and interarytenoid muscles. These muscles play a crucial role in voice production, coughing, and swallowing.
The right recurrent laryngeal nerve has a longer course than the left one. It loops around the subclavian artery in the chest before ascending to the larynx, while the left RLN hooks around the arch of the aorta. This anatomical course makes them vulnerable to injury during various surgical procedures, such as thyroidectomy and neck dissection, leading to potential voice impairment or vocal cord paralysis.
Hoarseness is a condition characterized by an abnormal change in the quality of voice, making it sound rough, breathy, strained, or weak. Medically, it's described as a disorder of phonation, which is the process of producing sound by vibrating the vocal cords in the larynx (voice box). Hoarseness can be caused by various factors, such as inflammation, irritation, or injury to the vocal cords, and may result in symptoms like altered voice pitch, volume, and clarity. It's essential to consult a healthcare professional if hoarseness persists for more than two weeks, especially if it's accompanied by other concerning symptoms like difficulty swallowing or breathing.
Laryngoscopy is a medical procedure that involves the examination of the larynx, which is the upper part of the windpipe (trachea), and the vocal cords using a specialized instrument called a laryngoscope. The laryngoscope is inserted through the mouth or nose to provide a clear view of the larynx and surrounding structures. This procedure can be performed for diagnostic purposes, such as identifying abnormalities like growths, inflammation, or injuries, or for therapeutic reasons, such as removing foreign objects or taking tissue samples for biopsy. There are different types of laryngoscopes and techniques used depending on the reason for the examination and the patient's specific needs.
Laryngeal nerve injuries refer to damages or injuries to the recurrent laryngeal nerve (RLN) and/or the superior laryngeal nerve (SLN), which are the primary nerves that supply the larynx, or voice box. These nerves play crucial roles in controlling the vocal cord movements and protecting the airway during swallowing.
The recurrent laryngeal nerve provides motor function to all intrinsic muscles of the larynx, except for the cricothyroid muscle, which is innervated by the superior laryngeal nerve. The RLN also carries sensory fibers from a small area of the mucous membrane below the vocal folds.
Injuries to these nerves can result in voice changes, breathing difficulties, and swallowing problems. Depending on the severity and location of the injury, patients may experience hoarseness, weak voice, breathy voice, coughing while swallowing, or even complete airway obstruction in severe cases. Laryngeal nerve injuries can occur due to various reasons, such as surgical complications (e.g., thyroid, esophageal, and cardiovascular surgeries), neck trauma, tumors, infections, or iatrogenic causes.
X-ray intensifying screens are medical imaging devices that contain phosphorescent materials, which emit light in response to the absorption of X-ray radiation. They are used in conjunction with X-ray film to enhance the visualization of radiographic images by converting X-rays into visible light. The screens are placed inside a cassette, along with the X-ray film, and exposed to X-rays during medical imaging procedures such as radiography or fluoroscopy.
The phosphorescent materials in the intensifying screens absorb most of the X-ray energy and re-emit it as visible light, which then exposes the X-ray film. This process increases the efficiency of the X-ray exposure, reducing the amount of radiation required to produce a diagnostic image. The use of intensifying screens can significantly improve the quality and detail of radiographic images while minimizing patient exposure to ionizing radiation.
Paralysis is a loss of muscle function in part or all of your body. It can be localized, affecting only one specific area, or generalized, impacting multiple areas or even the entire body. Paralysis often occurs when something goes wrong with the way messages pass between your brain and muscles. In most cases, paralysis is caused by damage to the nervous system, especially the spinal cord. Other causes include stroke, trauma, infections, and various neurological disorders.
It's important to note that paralysis doesn't always mean a total loss of movement or feeling. Sometimes, it may just cause weakness or numbness in the affected area. The severity and extent of paralysis depend on the underlying cause and the location of the damage in the nervous system.
Laryngeal diseases refer to conditions that affect the structure and function of the larynx, also known as the voice box. The larynx is a complex structure composed of cartilages, muscles, membranes, and mucous glands that play essential roles in breathing, swallowing, and vocalization.
Laryngeal diseases can be categorized into several types based on their causes and manifestations. Some common laryngeal diseases include:
1. Laryngitis: Inflammation of the larynx that can cause hoarseness, throat pain, coughing, and difficulty swallowing. Acute laryngitis is often caused by viral infections or irritants, while chronic laryngitis may result from prolonged exposure to smoke, chemicals, or acid reflux.
2. Vocal cord lesions: Abnormal growths on the vocal cords, such as polyps, nodules, or cysts, that can affect voice quality and cause hoarseness, breathiness, or pain. These lesions are often caused by overuse, misuse, or trauma to the vocal cords.
3. Laryngeal cancer: Malignant tumors that develop in the larynx and can invade surrounding structures, such as the throat, neck, and chest. Laryngeal cancer is often associated with smoking, alcohol consumption, and human papillomavirus (HPV) infection.
4. Laryngeal stenosis: Narrowing of the airway due to scarring or thickening of the tissues in the larynx. This condition can cause difficulty breathing, wheezing, and coughing, especially during physical activity or sleep.
5. Reinke's edema: Swelling of the vocal cords caused by fluid accumulation in the mucous membrane that covers them. Reinke's edema is often associated with smoking and can cause hoarseness, low voice, and difficulty projecting the voice.
6. Laryngeal papillomatosis: A rare condition characterized by the growth of benign tumors (papillomas) in the larynx, usually caused by HPV infection. These tumors can recur and may require repeated surgeries to remove them.
7. Vocal cord paralysis: Inability of one or both vocal cords to move due to nerve damage or other medical conditions. This condition can cause hoarseness, breathiness, and difficulty speaking or swallowing.
These are some of the common laryngeal disorders that can affect a person's voice, breathing, and swallowing functions. Proper diagnosis and treatment by an otolaryngologist (ear, nose, and throat specialist) are essential to manage these conditions effectively and prevent complications.
Postoperative complications refer to any unfavorable condition or event that occurs during the recovery period after a surgical procedure. These complications can vary in severity and may include, but are not limited to:
1. Infection: This can occur at the site of the incision or inside the body, such as pneumonia or urinary tract infection.
2. Bleeding: Excessive bleeding (hemorrhage) can lead to a drop in blood pressure and may require further surgical intervention.
3. Blood clots: These can form in the deep veins of the legs (deep vein thrombosis) and can potentially travel to the lungs (pulmonary embolism).
4. Wound dehiscence: This is when the surgical wound opens up, which can lead to infection and further complications.
5. Pulmonary issues: These include atelectasis (collapsed lung), pneumonia, or respiratory failure.
6. Cardiovascular problems: These include abnormal heart rhythms (arrhythmias), heart attack, or stroke.
7. Renal failure: This can occur due to various reasons such as dehydration, blood loss, or the use of certain medications.
8. Pain management issues: Inadequate pain control can lead to increased stress, anxiety, and decreased mobility.
9. Nausea and vomiting: These can be caused by anesthesia, opioid pain medication, or other factors.
10. Delirium: This is a state of confusion and disorientation that can occur in the elderly or those with certain medical conditions.
Prompt identification and management of these complications are crucial to ensure the best possible outcome for the patient.
Postoperative care refers to the comprehensive medical treatment and nursing attention provided to a patient following a surgical procedure. The goal of postoperative care is to facilitate the patient's recovery, prevent complications, manage pain, ensure proper healing of the incision site, and maintain overall health and well-being until the patient can resume their normal activities.
This type of care includes monitoring vital signs, managing pain through medication or other techniques, ensuring adequate hydration and nutrition, helping the patient with breathing exercises to prevent lung complications, encouraging mobility to prevent blood clots, monitoring for signs of infection or other complications, administering prescribed medications, providing wound care, and educating the patient about postoperative care instructions.
The duration of postoperative care can vary depending on the type and complexity of the surgical procedure, as well as the individual patient's needs and overall health status. It may be provided in a hospital setting, an outpatient surgery center, or in the patient's home, depending on the level of care required.

- Thirty-two patients with developing paralysis and acute WNV infection were identified. (cdc.gov)
- Acute paralysis associated with West Nile virus (WNV) infection ( 1 - 8 ) has been attributed to Guillain-Barré syndrome ( 3 ), a poliomyelitislike syndrome ( 2 , 4 - 6 , 8 ), and a generalized myeloradiculitis ( 1 , 7 ). (cdc.gov)
- Several reports have described acute respiratory failure occurring with WNV-associated paralysis ( 5 , 7 ). (cdc.gov)
- However, the frequency of acute paralysis in WNV neuroinvasive disease remains unknown, and the clinical features of WNV-associated respiratory weakness have not been characterized. (cdc.gov)
- Acute paralysis was seen in many patients, and in several, acute respiratory failure developed that required emergent intubation. (cdc.gov)
- We conducted a population-based assessment of WNV-infected persons in whom acute paralysis developed to describe the clinical features, mechanisms, and short-term outcomes. (cdc.gov)
Nerves1
- Histologic study of the laryngeal nerves in two cases confirmed the modern concept of laryngeal paralysis. (jamanetwork.com)
Neck3
- Stimulation applied directly to the neck may not reach the vocal cords, causing pain and potential damage to the other muscles within the neck. (vt.edu)
- It would transfer through the neck muscles to reach the nano-coil, which would then stimulate the vocal cords. (vt.edu)
- A generalized neck and head pain and temporary vocal cord paralysis are also possibilities. (harcourthealth.com)
Patient's1
- The appearance of the vocal cords on clinical exam can give insight into a patient's underlying problem. (medicalalgorithms.com)
Diagnostic1
- Idiopathic -An idiopathic vocal cord paralysis means that no specific cause could be found despite diagnostic tests. (mynorthtexasent.com)
Surgical1
- From 1985 to 1995 cancer was the primary cause for vocal cord paralysis, however this shifted to primarily iatrogenic surgical injury from 1996 to 2005. (rowan.edu)
Midline3
- The paralyzed cord generally lies 2 to 3 mm lateral to the midline. (msdmanuals.com)
- and dyspnea with moderate exertion as each cord is drawn to the midline glottis by an inspiratory Bernoulli effect. (msdmanuals.com)
- The cord is adducted (in the midline) when there is complete paralysis of the recurrent laryngeal nerve on that side. (medicalalgorithms.com)
Nerve4
- In recurrent laryngeal nerve paralysis, the cord may move with phonation but not with inspiration. (msdmanuals.com)
- In the other case of a supraclavicular lesion of one recurrent nerve the paralyzed cord was seen in the paramedian position. (jamanetwork.com)
- The paralysis affects all laryngeal muscles, including the cricothyroid (which is spared if the recurrent laryneal nerve alone is injured). (medicalalgorithms.com)
- The recurrent laryngeal nerve (RLN) carries signals to different voice box muscles responsible for opening, closing, and adjusting tension in the vocal cords. (mynorthtexasent.com)
Lung1
- Left vocal cord paralysis, lung function and exercise capacity in young adults born extremely preterm with a history of neonatal patent ductus arteriosus surgery-A national cohort study. (uib.no)
Phonation1
- Paralysis may affect phonation, respiration, and deglutition, and food and fluids may be aspirated into the trachea. (msdmanuals.com)
Speech1
- Our certified and licensed speech-language pathologists are specially trained and have the expertise to provide a comprehensive evaluation of voice production and develop a therapeutic program to improve vocal quality. (adventisthealth.org)
