Over the past few decades, laser surgery has completely changed the clinical practice of doctors of various specialties, including otorhinolaryngologists.
Objective: to analyze the effectiveness of surgical treatment using combined surgery with a photoangiolytic laser in a patient diagnosed with temporal bone paragangliomas.
Material and methods. Surgical treatment of a 42-year-old woman with a diagnosis of type A temporal paraganglioma was performed on the basis of the FBSI SCCO. We used the settings of the 445 nm high-power photoangiolytic laser and shortened the working cycles at the highest power of 10 W; a very short time duration of impulses and a distance of 1–3 mm from the target tissue was used for photoangiolysis.
Results. The tumor of the right middle ear was revealed on the X-ray examination (MSCT of the temporal bones). During revision of the tympanic cavity under conditions of moderate bleeding, a tumor was removed while maintaining the auditory ossicles. The vessels supplying the tumor were coagulated using a photoangiolytic laser with a wavelength of 445 nm.
Conclusions. The ability to remove a tumor of the middle ear with minimal blood loss in the pre- and postoperative periods without damaging the surrounding structures of the inner and middle ear was achieved. In the future, it is planned to conduct an analysis of long-term postoperative changes both at the tissue and functional levels. Such data can only be obtained after 36 months from the date of the operation, and after the sufficient number of operations using this technique will be reached.
