[Clinical implications of laryngeal echosonography in cancer diagnosis].

Laryngeal echosonography was made in 50 healthy subjects and 186 patients with laryngeal cancer to evaluate efficacy of ultrasound in diagnosis of laryngeal cancer. The study revealed sonographic characteristics typical for laryngeal cancer, endophytic tumors, in particular. Ultrasound can assess involvement of the laryngeal cartilages and severity of their lesion, invasion of the tumor into the underlying tissues and cervical organs. The tumor can be verified by puncture aspiration biopsy using ultrasound monitor. All this allows more effective choice of an optimal treatment method and planning of the scope of surgical intervention.
