[Mastoid osteoma].

Osteomas of the temporal bone are rare, especially osteomas originating from the mastoid process. Most often occur in women aged 20-30 years. The maximum growth rate is observed during puberty.

[Application of allogenous dural membrane (brefotissue DM) in surgical treatment of retraction pockets of the tympanic membrane].

Introduction: The tactics of treating patients with retraction pockets of the tympanic membrane is still debatable. When choosing surgical treatment, preference is given to the removal of the retraction pocket with simultaneous reconstruction of the posterior-upper wall of the external auditory canal (retraction area) with a cartilage or fascial flap, autologous bone, or a combination of the above tissues. Considering the well-known negative aspects of the use of all the mentioned grafts, there is a need to find new types of tissues to strengthen the retraction pocket.

[The influence of signs of dysmorphophobia on the evaluation of the result of rhinoplasty].

The object of the clinical research was 367 patients after rhinoplasty. All patients before the operation fill in a special questionnaire, allowing to evaluate quantify the signs of dysmorphophobia. Patients with low index of dysmorphophobia (within 5-6 points) adequately estimated the result of the operation because their opinion coincided with the opinion of the doctor and in some cases they didn't notice even insignificant defects the doctor saw.

[The use of retinoids to stimulate the regenerative process in trepanation cavity after "open" sanitizing surgery on the middle ear].

Introduction: One of the methods of surgical treatment of patients with chronic purulent otitis media is an "open" sanitizing surgery on the middle ear. One of its important features is the formation of a wound surface that communicates with the external environment, which subsequently leads to infection, lengthening the time for epithelization, and in 13-30% of cases, the latter is incomplete with the development of a "trepanation cavity disease".

Objective: To establish the nature of the effect of retinoid-based drugs on the severity of the inflammatory process and the regeneration processes in the tissues of the trepanation cavity after sanitizing operations on the middle ear.

[Application of bone-plastic materials for mastoidoplasty].

The aim of this study is comparative assessment of of different bone-plastic materials for mastoidoplasty. The study included 30 patients who underwent 'canal wall down' mastoid surgery with mastoidoplasty. The following criteria were used for comparing: 1) simplicity of modeling of the material 2) the wound healing process 3) osteointegration - the process of formation of 'new bone' tissue (CT of temporal bones 6 and 12 months after oreretion).
