1/7. Unusual endolaryngeal extension of a large thyroglossal duct cyst.INTRODUCTION: Thyroglossal duct cysts account for approximately 70% of congenital neck abnormalities. hoarseness of voice and the extension of the cyst into the larynx are very uncommon. CLINICAL PICTURE: We present a patient with a long history of a large thyroglossal cyst who developed progressive hoarseness of voice. The cyst had protruded into the larynx producing the appearance of a laryngeal neoplasm. Computed tomography (CT) clearly demonstrated the nature of the cyst and its encroachment into the larynx. TREATMENT: This was safely excised with a Sistrunk procedure and a temporary tracheostomy to maintain a secure airway, in view of the possibility of postoperative supraglottic oedema. CONCLUSION: Endolaryngeal extension of the thyroglossal duct cyst is rare. Evaluation of unusual large midline neck masses should include a CT scan. The intralaryngeal component of the cyst can be easily dissected off from the neighbouring structures during dissection in the Sistrunk procedure. A tracheostomy may be needed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/7. Mesenchymal chondrosarcoma of the vagus nerve.Mesenchymal chondrosarcoma is a rare, aggressive, malignant neoplasm, which arises from extraskeletal sites in 30-40 per cent of cases. It is extremely rare in children. We present a novel case of childhood mesenchymal chondsarcoma arising from the vagus nerve in the neck, resulting in paralysis of the right vocal fold. The clinicopathologic features and management of this case are described along with a brief discussion on the aetiology of vocal fold paralysis in this age group. Current literature on extraskeletal presentation of mesenchymal chondrosarcoma is reviewed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/7. Delayed onset of vocal cord paralysis after explantation of a vagus nerve stimulator in a child.INTRODUCTION: vagus nerve stimulation for the management of intractable seizure disorders is increasingly being used, especially in younger children. Although complications such as infection or vocal cord paralysis are uncommon, some may be unreported. CLINICAL PRESENTATION: A 3.5-year-old boy with intractable complex partial and generalized seizures had a left vagus nerve stimulator (VNS) successfully implanted. Two weeks later, the cervical incision showed signs of infection, antibiotics were started, and the VNS generator and leads were explanted. Three weeks later the child's mother noted a change in the voice of her son, as well as increased coughing and gagging. Flexible laryngoscopy identified a left vocal cord paralysis, which eventually resolved after 6 months. CONCLUSION: infection requiring explantation of a VNS is uncommon. The risk is higher in younger children, especially in those who are developmentally delayed. These children may continuously drool, with saliva or food soiling the fresh incision, or even pick at the incision to the point of twisting or even pulling out the electrodes. Less common is a vocal cord paralysis, especially occurring in a delayed fashion.- - - - - - - - - - ranking = 0.046278848069467keywords = complex (Clic here for more details about this article) |
4/7. Ancient schwannoma of the true vocal cord.Ancient schwannomas are benign nerve origin neoplasms that may cause difficulties in the differential diagnosis with other benign or malignant tumors. They usually occur in the head and neck region (epiglottis, arytenoepiglottic fold, false vocal cord). Involvement of the true vocal cords is extremely rare (less than 10 cases have ever been reported in the English literature--mainly in women). The present case describes a 27-year-old man who presented with a 2-year history of hoarseness. Indirect laryngoscopy showed a small polypoid mass in the middle of the left vocal cord. During microlaryngoscopy under general anesthesia, the polypoidal mass was removed and sent for histology. immunohistochemistry and detailed histological examination revealed an ancient schwannoma. The present case in a male patient aims to increase awareness of the possibility that these tumors may also exist in the true vocal cords mimicking other more frequent lesions.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/7. Anesthetic management for laser excision of recurrent respiratory papillomatosis in a third trimester parturient.Recurrent respiratory papillomatosis (RRP) is characterized by the development of laryngeal papillomas, which can produce partial to complete upper airway obstruction. patients with RRP often require intermittent surgical excision to treat symptoms such as hoarseness and stridor, and to control progression of the lesions. The anesthetic management of such patients is challenging, and it requires carefully coordinated care between an anesthesiologist and otolaryngologist. We present 2 cases of general anesthesia administration during surgical excision of laryngeal papillomas, both occurring during the third trimester of separate pregnancies in the same parturient. The complexity of management was amplified in these cases because of the physiological and anatomical changes associated with pregnancy, along with the need to monitor fetal well-being. Possible complications included complete airway obstruction, pulmonary aspiration of gastric contents, hypoxemia, fetal distress, and preterm labor. Because pregnancy may lead to activation of human papillomavirus, the causative organism of RRP, management guidelines are provided for anesthesiologists who may care for patients with RRP during pregnancy.- - - - - - - - - - ranking = 0.046278848069467keywords = complex (Clic here for more details about this article) |
6/7. Multiple cervical bronchogenic cysts.Bronchogenic cysts are rare, benign, congenital lesions that occur as a result of aberrant development of the tracheobronchial tree during embryogenesis. They usually present during the first decade of life and are encountered predominantly within the mediastinum or the lung parenchyma. In a few instances, they appear within the neck mimicking a neoplasm and, depending on their size and site, may also cause acute upper respiratory obstruction. We describe a case of two cervical bronchogenic cysts adjacent to the larynx in a child who presented with a hoarse voice.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/7. Medullary carcinoma of the thyroid as a laryngeal problem.A neuroendocrine secreting tumor, initially presenting as a laryngeal problem, is reported. Subglottic biopsy, first interpreted as paraganglioma, was finally diagnosed as medullary carcinoma of the thyroid. The complex testing required to arrive at an accurate diagnosis of this uncommon thyroid malignancy is discussed. The sparse occurrence of the neoplasm in the laryngologic field, as well as the necessity for differentiating it from other neuroendocrine tumors, bear consideration.- - - - - - - - - - ranking = 1.0462788480695keywords = neoplasm, complex (Clic here for more details about this article) |
