We have studied 40 patients to see if cricoid pressure affects the success rate of ventilation through, and the position of, the laryngeal mask and subsequent fiberscope-aided tracheal intubation. Adequate ventilation of the lungs was produced through the laryngeal mask in 19 of 20 patients in the control group, but in only 10 of 20 patients in the cricoid pressure group (P < 0.002). The laryng...

Laryngeal hemangiomas are relatively rare. Laryngeal hemangiomas occur in two main forms--infantile and adult laryngeal hemangiomas. While infantile hemangiomas are usually found to occur in the subglottis, adult hemangiomas occur commonly in the supraglottic regions of the larynx. Laryngeal hemangioma with cavernous features isolated to the free edge of the vocal fold is a very rare clinical f...

background: various studies are seeking to find new methods to improve techniques of laryngeal mask airway (lma) insertion and reduce possible complications. in this study, we embarked on a clinical study to investigate the advantages of a new insertion method of laryngeal mask and to compare it with the classic method. materials and methods: two hundred patients aged 20-60 years old in 2012 we...

Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...

The dog was hit by a car and immediately after the accident no abnormalities were present. One month later there were changes in phonation and dyspnea. Considerations were laryngeal paralysis, laryngeal neoplasia, abscess, cyst, granuloma, or hematoma. Laryngeal collapse due to chondromalacia was considered less likely due to the breed. The laryngeal lumen was narrow with an irregular mucosal s...

Changes in laryngeal resistance to airflow have been measured in rabbits during spontaneous breathing, while larynx was isolated "in situ". Intravenous injections of serotonin resulted in variable apnoea followed by rapid, shallow breathing, coupled with increases in laryngeal inspiratory and expiratory resistances. These laryngeal responses persisted after cutting vagi in the chest. The "centr...

Laryngeal cancer is a disease of old age and the most common age of presentation is 6Th. 7Th decade of life. This disease is more common in men, but male to female ratio has been decreased from 15:1 to 4:1 during the last forty years. The most common risk factors are cigarette smoking and alcohol consumption. This cross – sectional study carried out to determine the age of laryngeal cancer from...
