[Crista galli pnevmatization: prevalence and clinical significance].

Objective: Determine the frequency of (crest of the rooster) pneumatization and the presence of communication of the pneumatized with the paranasal sinuses.

Material And Methods: Computed tomography data of the paranasal sinuses of 251 patients. The patients' age ranged from 23 to 70 years.

[Rare observation of petrositis complicated by parapharyngeal abscess in an 8-year-old patient].

A clinical case of diagnosis and treatment of an 8-year-old patient with bilateral acute suppurative otitis media (ASOM) complicated by left mastoiditis and petrositis is presented. By itself, such a rare complication of ASOM as petrositis manifested itself not in the form of the classic Gradenigo triad, but as a parapharyngeal abscess (PPA), due to the destruction of the lower wall of the temporal bone pyramid. Complications arose as a result of contact and hematogenous pathways for the spread of the infection, which debuted in the middle ear cavities 1 month before the patient was admitted to the hospital.

[Comparative morphological assessment of the damaging effects of cold plasma and radio wave energy on the mucous membrane of the lip in the experiment].

Unlabelled: The aim of this study was a comparative morphological assessment of changes in the mucous membrane of the lip in the field of radio wave and cold plasma exposure in the experiment.

Material And Methods: Experimental animals removed a portion of the mucous membrane of the inner surface of the lip with a Surgitron radio knife (group 1) and an electrode of the Coblator II cold plasma apparatus (observation group 2). Tissue was taken from the edge of the surgical wound as a trapezoidal flap containing mucous and submucous membranes immediately after the incision and 3 weeks after the surgery.

[Quantification of the loudness of snoring according to Watch-PAT-200 and its relationship with the severity of obstructive sleep apnea syndrome].

Purpose Of The Study: Evaluate the capabilities of Watch-PAT-200 in obtaining data to determine the relationship between the loudness of snoring and the severity of obstructive sleep apnea syndrome (OSAS).

Material And Methods: From 2017 to 2019, 208 patients with complaints of nocturnal snoring were examined. Apnea / hypopnea indices (AHI) and respiratory distress index (RDI) were assessed.

[Comparative cytological analysis of the middle ear exudate in different children's groups].

Unlabelled: The purpose (EOM) with congenital clefts of the lip/palate (CCLP) and without CCLP, determining the stages of chronic disease and the significance of surgery on the middle ear.

Patients And Methods: Two clinics was parallel conducted a cytological examination of exudate of the middle ear in children. The first group consisted of 30 patients aged 2 to 17 years with EOM without CCLP (n=54 ears).
