introduction: cigarette smoking and alcohol consumption have a well-known effect on the development of upper aerodigestive tract carcinomas, but such a role for opium is questionable. this study was designed to assess the correlation between opium inhalation and cancer of the larynx and upper esophagus. materials and methods: fifty eight patients with laryngeal cancer, ninety eight patients wit...

background: potassium permanganate (pp) is a highly corrosive and deadly agent with a reported lethal dose of 10 g in adults. in this report, successful treatment of a patient poisoned with three times the lethal dose of pp is presented, and effective and early approach to such emergency toxicologic condition is discussed. case presentation:a 24-year-old woman presented to emergency room of our...

conclusions endoscopic keel placement should be done with heavy suture through cricothyroid and thyrohyoid membranes. surgeons should suture the keel to the anterior laryngeal wall with specially designed lichtenberger’s needle-carriers to prevent complications such as keel aspiration, adhesion formation and imposing a second trip under general anesthetics, which put the patient at increased ri...

The superior laryngeal artery is the principal artery supplying the laryngeal mucosa, musculature, and glands. Knowledge of variations in the origin of superior laryngeal artery could prove to be very useful during reconstructive surgeries of the larynx, partial laryngectomy, laryngeal transplantation, and also during procedures like super-selective intra-arterial chemotherapy for laryngeal and...

INTRODUCTION Laryngeal tuberculosis used to be a common complication in advanced pulmonary tuberculosis. However, it has become a rare occurrence in developed countries since the introduction of antituberculous agents. Moreover, the pattern of the disease has changed over the years. Nowadays, it more closely resembles a laryngeal carcinoma than any other laryngeal illness. CASE PRESENTATION W...

Congenital Laryngeal Paralysis Congenital laryngeal paralysis has been reported in Bouviers des Flandres, bull terriers, Dalmatians, rottweilers, and huskies. Bouviers des Flandres and bull terriers have mostly been reported from Europe, the Dalmatians and huskies from the United States. Laryngeal paralysis has a hereditary transmission in Bouvier des Flandres with an autosomal dominant trait. ...

We have reported two male patients presenting with hoarseness and stridor respectively to the outpatient department, with later requiring emergency tracheostomy as life saving procedure. Endoscopic excision biopsies of the laryngeal lesions were performed and histopathological examination revealed amyloidosis. In the first patient, endoscopic excision of the mass was done with cold knife and in...

Pulmonary sequestration (PS) and pneumomediastinum are two rare clinical diseases. Pneumomediastinum was generally observed in infants either with diseased lungs or who were performed assisted ventilation or resuscitation following birth. It was reported in patients with existing ectopic thoracic kidney and laryngeal cysts however, no coexisting congenital lung anomalies were reported. Here, we...

We present a study of the acoustic source parameters describing glottal flow waveforms generated by the two-mass model for vocal fold oscillations. Numerical measurements of the acoustic parameters as a function of model parameters are presented. Conclusions are drawn from these results, concerning the correlations between acoustic parameters, the effect of the vocal tract, the different regime...

Acute airway obstruction in the adult can be caused by a rapidly enlarging laryngeal cyst that may present unusually as a midline neck mass. In this case report we present a different surgical technique for the removal of a large combined laryngocele via midline transcervical approach that did not require laryngofissure. This technique allowed simple and fast access, excellent exposure and comp...
