[The results of laser-assisted piston stapedoplasty in the patients with otosclerosis].

The objective of the present study was to compare the immediate result of laser-assisted piston stapedoplasty with the use of prosthetic stapes of different diameter in the patients with otosclerosis. The patients of both (study and control) groups underwent the measurement of the bone conduction (BC) auditory threshold before, 10-12 days, and 1 month after surgery. The bone-air interval (BAI) was measured in the same time periods.

[Diagnostics of endolymphatic hydrops].

The objective of the present work was to analyse the methods for diagnostics of endolymphatic hydrops associated with Miniere's disease most frequently employed in clinical practice using both the data from the world scientific literature and our own 25-30 year experience based on the observation of more than 500 patients. Camertonal studies of hearing acuity estimated from the results of air conduction measurements and relevant acoumetric curves were considered. The main methods of research are discussed including such as tonal threshold audiometry, ultrasound testing, loud sound lateralization, dehydration test, extratympanic electrocochleography, otoacoustic emission, and functional computed stabilometry.

[The retrospective clinical study of labyrinthine fistula associated with chronic suppurative otitis media and their treatment].

The objective of the present retrospective study was to estimate the efficacy of various surgical techniques employed to treat the patients presenting with chronic suppurative otitis media (CSOM) and concomitant cholesteatoma complicated by labyrinthine fistula. The authors present an overview of the literature concerning diagnostics and results of the surgical treatment of labyrinthine fistula (LF) in the patients with CSOM and concomitant cholesteatoma. The original studies included 157 patients with this condition complicated by labyrinthine fistula.

[Differential atticoanthrotomy with type 1 tympanoplasty as the method of choice for the treatment of chronic perforating otitis media with expressed mucositis].

The authors report the results of surgical treatment of 37 patients (42 ears) presenting with chronic perforating otitis media and grade I-III mucositis. All the patients were treated by differential atticoanthrotomy with type 1 tympanoplasty. Most of them suffered seriously disturbed ventilation and drainage functions of the Eustachian tube.

[The results of stapedoplasty with the use of an auricular autocartilage as a stapes bone prosthesis in the patients presenting with a mixed form of otosclerosis].

The authors present immediate and long-term results of stapedoplasty with the use of an auricular autocartilage as a stapes bone prosthesis in 52 patients presenting with mixed (types I and II) otosclerosis. The surgical procedure is described in considerable detail. The average bone-conduction auditory threshold was shown to slightly increase depending on the duration of the disease (less than and over 15 years): by 5 dB and 9 dB in mixed otosclerosis of types I and II respectively.
