[Reaction of regional lymph nodes of the middle ear during ultrasound lymphotropic therapy of exudative otitis media (experimental study)].

The article is devoted to structural changes in the regional lymph nodes of the middle ear (superficial, facial and deep cervical lymph nodes) in experimental animals (30 male Wistar rats) when modeling exudative otitis media and after a 7-day course of local ultrasound lymphotropic therapy. The method of conducting the experiment is described. Comparative morphological and morphometric studies of lymph nodes were carried out on the 12th day from the beginning of otitis modeling and evaluated according to 19 criteria: node cut-off area, capsule area, marginal sinus, interstitial part, paracortical area, cerebral sinuses, brain cords, area number and area of primary and secondary lymphoid nodules, area of germinal centers, specific areas of the cortex and medulla oblongata, sinus system, T-dependent and B-dependent zones, cortical-cerebral index.

[Ultrasound regional lymphotropic therapy for protracted forms of serous otitis media].

Unlabelled: The article is devoted to the clinical substantiation of the effectiveness of ultrasound regional lymphotropic therapy in protracted forms of serous otitis media (SOM).

Objective: To improve the method of conservative treatment of patients with protracted forms of SOM by clinically substantiating and developing a method of ultrasound regional lymphotropic therapy.

Material And Methods: The study included 75 patients (102 cases of diseased ears) with SOM.
