METHOD FOR INTRAOPERATIVE TOPICAL DIAGNOSIS OF RECURRENT LARYNGEAL NERVES WHEN PERFORMING RADICAL SURGICAL OPERATIONS ON THYROID GLAND Russian patent published in 2016 - IPC A61B5/00 A61B17/00 A61B17/30 A61M16/06 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to endocrine surgery, and can be applied in intraoperative diagnosis of recurrent laryngeal nerves. Laryngeal mask is used as anaesthetic mean. During subfascial extraction of thyroid gland by blunt and sharp ways, simultaneous stimulation of anatomical formation, assumed as recurrent laryngeal nerve, and identification of vocal folds mobility, are conducted. Stimulation of anatomical formation is performed by application of galvanic forceps. Identification of vocal folds mobility is conducted by graphic recording on display of artificial pulmonary ventilation apparatus in mode of value controlled venting of peak inspiratory pressure to Paw_init and at the moment of Paw irritation of anatomical formation assumed as recurrent laryngeal nerve. At higher Paw unlike Paw_init more than 2 cm of water column, mobility of vocal folds is diagnosed that testifies the above anatomical formation as return laryngeal nerve.

EFFECT: method simplifies intraoperative topical diagnosis of recurrent laryngeal nerves, reducing rate of treatment-induced injuries of recurrent laryngeal nerves and complications of anesthesia care, owing to use of laryngeal mask, galvanic forceps, and evaluation of difference of peak inspiratory pressure before and after irritation of anatomical formation assumed as recurrent laryngeal nerve.
