Familial vocal cord dysfunction 总被引:2,自引:0,他引:2
Vocal cord paralysis is a common cause of neonatal stridor. Familial vocal cord dysfunction, however, is unusual. All three siblings in one family had neonatal stridor. Vocal cord dysfunction was confirmed after endoscopic examination in two of the children; a temporary tracheotomy was required by one child. Results of evaluation, including pulmonary function tests, suggest discrete dysfunction localized to the neuromuscular pathway responsible for vocal cord abduction. Endoscopy is of prime importance in the diagnosis of vocal cord dysfunction. In considering therapy, the physician must weigh both the potentially life-threatening nature of vocal cord paralysis, as well as the likelihood of eventual spontaneous resolution of many familial and idiopathic cases. 相似文献

A paralysis of the left vocal cord was seen by laryngoscopy in a 3-days-old boy with inspiratory stridor. A ductus aneurysm was established by angiocardiography, which was believed to be the cause of the vocal cord paralysis. Within 8 days after the angiocardiography the aneurysm became smaller and the stridor disappeared. Twelfth months later the control-angiocardiography showed the total obliteration of the ductal aneurysm. 相似文献

During an 18-month period in a pediatric intensive care unit, nine patients with vocal cord paralysis were identified using flexible bronchoscopy. When tracheally extubated, each child was found to have stridor. The children ranged in age from 17 days to 5 1/2 years. Two patients had unilateral paralysis, but neither required tracheostomy. Seven patients displayed bilateral abductor vocal cord paralysis. Of these, six patients required tracheostomy. Surgical injury to the recurrent laryngeal nerve was the probable cause in two patients. The other seven patients had neurologic disorders with documented or suspected increases of intracranial pressure. Four of the seven patients with bilateral abductor vocal cord paralysis regained cord mobility within 4 months. Both children with unilateral cord paralysis have no stridor and vocalize well 1 year later. Cord paralysis in the setting of intracranial hypertension probably results from compression or ischemia of the vagus nerve before it exits the skull. Early visualization of the larynx should be done in patients who become stridulous when extubated, especially those with prior thoracic procedures or with neurologic disorders associated with intracranial hypertension. 相似文献

Five cases of unilateral vocal cord paralysis/paresis were diagnosed following extracorporeal membrane oxygenation for newborn respiratory failure. All were right sided and transient in nature. None of the five patients had other findings commonly associated with vocal cord palsy. The extracorporeal membrane oxygenation procedure requires surgical dissection in the carotid sheath on the right side of the neck, an area immediately adjacent to both the vagus and recurrent laryngeal nerve. It is speculated that vocal cord paralysis in these infants was acquired as a result of the extracorporeal membrane oxygenation cannulation. Although the vocal cord paralysis resolved in all cases, two patients had difficult courses after extracorporeal membrane oxygenation. Therefore, laryngoscopic examination should be considered for patients after extracorporeal membrane oxygenation. 相似文献

The upper airway extends from the nasal aperture to the subglottis and can be the site of multiple types of congenital malformations leading to anatomical or functional obstruction. This can cause severe respiratory distress. Newborns are obligate nasal breathers; therefore nasal obstruction can lead to airway compromise and respiratory distress. The etiologies are varied and include, choanal atresia, pyriform aperture stenosis, and rarely tumors such as glioma, encephalocele, teratoma, or dermoid. More common upper airway congenital anomalies include laryngomalacia, vocal cord paralysis, and subglottic stenosis. Laryngolmalacia is the most common congenital laryngeal anomaly. Inspiratory stridor often does not present until two weeks after birth and resolves by 18 months of age. Most cases are managed with watchful waiting. Severe cases require a surgical intervention. Bilateral vocal cord paralysis is usually idiopathic. In certain cases, paralysis may occur secondary to central nervous system abnormality including Arnold-Chiari malformation, cerebral palsy, hydrocephalus, myelomeningocele, spina bifida, or hypoxia. Severe cases may necessitate endotracheal intubation and tracheostomy. Congenital subglottic stenosis is the third most common laryngeal anomaly. It is defined as a diameter of less than 4mm of the cricoid region in a full-term infant, and less than 3mm in a premature infant. This condition is the most common laryngeal anomaly that requires tracheotomy in newborns. Laryngotracheoplasty may be required to achieve decanulation. Knowledge of the upper airway embryological development and congenital anomalies is off prime importance in assessing the newborn with respiratory distress. In most cases flexible endoscopy establishes the diagnosis. Management is tailored to each condition and its degree of severity. 相似文献

Myelomeningocele with Chiari II malformation and hydrocephalus is a common association seen in infants with a congenital failure of neurulation. Here we report two cases of such an association presenting with different sets of problems. The first patient presented with severe inspiratory stridor due to bilateral abductor vocal cord paralysis, which was relieved completely within 24 h of definitive surgery. The second patient experienced intraoperative cardiac arrest. Definitive surgery was followed after successful cardiopulmonary resuscitation. The cause of the perioperative sequence of events in both cases is attributed to the associated pathologies of Chiari II malformation. 相似文献

Between 1998 and 2000, four newborns have been observed for laryngeal stridor occurred some hours after birth. Otorhinolaryngologic examinations, as well as cardiac, neuroradiologic and serologic investigations have been performed to formulate the diagnosis and verify the etiology. The fiberoptic laryngoscopy showed a bilateral paralysis of the vocal cord in two newborns, a monolateral paralysis of the left vocal cord in another and in the last one, instead, a bilateral cordal hypomobility. The follow-up performed till the age of one year showed a complete remission of the symptomatology in two newborns, respectively in the one with monolateral paralysis and in the other affected by hypomobility of the vocal cords; of the two newborns with bilateral paralysis, instead, one is dead because of Haemophilus Influenzae epiglottitis, three weeks after discharge without physicians' consensus, while in the other patient, affected by lobar holoprosencephaly, it was necessary to perform a tracheotomy because of a severe obstructive apnea. The lobar holoprosencephaly, is a cerebral malformation characterized by the partial separation of the cerebral hemispheres, and it is described for the first time associated with bilateral vocal cords paralysis. 相似文献

We present 3 cases of bilateral vocal cord palsy who presented with acute respiratory distress with features of upper airway obstruction requiring tracheostomy. No cause could be found despite clinical evaluation and laboratory investigations. This diagnosis should be considered when child presents with upper airway obstruction emergency after ruling out other important causes of stridor and laryngoscopic examination is warranted in such cases for diagnosis. 相似文献

Hereditary neuralgic amyotrophy is a rare autosomal dominant disorder involving recurrent episodes of painful brachial plexus neuropathies. Involvement of other nerves has been described in some families. The age of onset is from infancy to adulthood. Mutations in the SEPT9 gene were identified in approximately half of the hereditary neuralgic amyotrophy families.We evaluated a family with six affected members from three generations with a point mutation in the SEPT9 gene. One of the patients presented in the neonatal period with vocal cord paralysis necessitating intubation and prolonged ventilation.The neonatal presentation of vocal cord paralysis broadens the phenotypic spectrum of hereditary neuralgic amyotrophy. The identification of a SEPT9 mutation in a neonate with respiratory distress due to vocal cord paralysis expands the differential diagnosis in these patients. 相似文献

This report describes 21 infants and children with bilateral abductor vocal cord paralysis and associated meningomyelocele, Arnold-Chiari malformation, and hydrocephalus. Two life-threatening forms of respiratory distress are distinguished: (1) upper airway obstruction due to bilateral abductor cord paralysis and (2) apnea. Clinically significant episodes of apnea were documented in 13 infants. Ten infants had evidence of aspiration and dysphagia. Vocal cord paralysis, apnea, aspiration, and dysphagia were frequently temporally related to increased intracranial pressure. 相似文献

Congenital stridor is one of the rare presentations of respiratory distress at birth. The commonest cause of congenital stridor
is laryngomalacia, which accounts for 60% of the causes. The other common causes are congenital subglottic stenosis and vocal
cord palsy (VCP). VCP is usually unilateral and most often linked with birth trauma, and is temporary. Bilateral palsy can
be associated with other congenital anomalies. The current report describes a case of congenital bilateral VCP, not related
to birth trauma and severe enough to require tracheostomy. 相似文献

Congenital airway anomalies (CAA) include a variety of conditions that cause respiratory distress in neonates and infants. These malformations occur at various anatomic levels and manifest in a wide spectrum of airway symptoms, with presentation significantly influenced by the level at which obstruction occurs as well as by the severity of obstruction. The prevalence of congenital airway malformations has been estimated to range between 0.2 and 1 in 10,000 live births. The most frequent CAA are laryngomalacia, bilateral vocal cord paralysis, subglottic stenosis, laryngeal webs, subglottic hemangioma, tracheomalacia, congenital tracheal stenosis, laryngotracheal cleft, and tracheal agenesis. 相似文献

Upper airway obstruction is commonly misdiagnosed as asthma. We report on four children with recurrent respiratory symptoms who had been erroneously diagnosed as having asthma and who received anti‐asthma medication for several years. The evaluation of spirometry tracing was neglected in all cases. Subglottic stenosis, tracheomalacia secondary to tracheo‐esophageal fistula, double aortic arch, and vocal cord dysfunction were suspected by direct inspection of the flow–volume curves and eventually diagnosed. The value of clinical history and careful evaluation of spirometry tracing in children with persistent respiratory symptoms is critically discussed. 相似文献

We describe two adolescent patients in whom a disorder of the vocal cords associated with emotional factors resulted in acute episodes of stridor. Adduction of the vocal cords on inspiration and abduction on expiration was found on indirect laryngoscopy. The problem responded to either placebo treatment or psychotherapy. The similarity between vocal cord dysfunction presenting as stridor and that presenting as asthma is discussed. The importance of diagnosing these functional problems in children is emphasized in order to avoid unnecessary diagnostic procedures and hazardous treatment. 相似文献

An eleven month old infant girl presented with a two-month history of inspiratory stridor. Analysis of her symptoms indicated airway obstruction located in the middle of the trachea; a barium esophagogram revealed an esophageal foreign body with tracheal compression. By endoscopy, a chestnut shell was extracted from the esophagus. In infancy, esophageal foreign bodies may cause mainly respiratory symptoms. 相似文献

Most patients with thymic cysts complain of a slowly enlarging, asymptomatic cervical mass. Only 6–10% suffer dysphagia, dyspnoea,
stridor, cervical pain or vocal paralysis. In some rare cases sudden onset of severe dyspnoea or asphyxia is the first symptom,
especially in neonates and small infants. We report a unique case of a 20-month-old child, who required emergency tracheal
intubation due to asphyxia. Cervicomediastinal thymic cyst might need to be included in causes of life-threatening airway
obstruction in young children. 相似文献
