FEATURES OF PREOPERATIVE MANAGEMENT AND METHODS OF EXAMINATION OF PATIENTS OF GROUPS UNDER RESEARCH

Despite the active ability to repair, it is frequently noticed that the independent potentialof bone tissue is insufficient, that is a serious problem in reconstructive maxillofacialsurgery, orthopedics and traumatology. In recent years, there has been an activesearch for implant material that would match the autologous bone in its properties andcharacteristics. Tissue engineering technologies allow to create tissue equivalents tobone tissue using autogenous stromal cells deposited on biocompatible or biologicalmaterial of tissue engineering design. The article presents the features of preoperativemanagement, description of the used examination methods and bone augmentationmaterials in patients of the groups under study.Objective – to use a set of adequate methods of examination and optimal preoperativemanagement of patients of the group under study during sinus lifting, post-extractionsocket preservation, osteosynthesis for mandibular fractures and impacted wisdom teethextraction, which were accompanied by the use of bone augmentation materials based onmultipotent mesenchymal stromal cells.Material and methods. 280 people aged 18 to 55 with partial or complete adentiaand atrophy of the alveolar process of the jaws, with chronic periodontium infectionand chronic generalized periodontitis, with fractures and impacted third molars wereexamined in the Department of Surgical Dentistry and Maxillofacial Surgery of theChernivtsi Regional Clinical Hospital. All patients were planned to make orthopedicstructures based on dental implants.Results. The use of computed tomography in preoperative examination of patients in thestudied group allows not only visually to examine the object, but also to perform directdensitometric analysis with measurement of attenuation coefficients in Hounsfield units,that is a significant advantage over X-ray examination.Conclusions. The use of bone augmentation materials based on multipotent mesenchymalstromal cells of adipose tissue during dental operations improves the regenerativeproperties of bone tissue and helps to reduce the duration of inpatient treatment.

Diagnosis and treatment of hygroma of the wrist joint in the practice of an outpatient surgeon

Introduction. Synovial cyst or hygroma is a common disease that occurs in both children and adults, but it is most often observed in people 20–45 years old. More than 60% of patients who go to the polyclinic with complaints about the presence of tumor-like formations have hygroma.Goal. Analysis of the results of treatment of synovial cysts of the hand and wrist joint according to our own observations and literature data.Material and methods. We observed 54 patients suffering from hygroma of the hand and wrist joint, who were treated in polyclinic No. 2 and MEDEL multidisciplinary clinic in Kazan from 2005 to 2020. The treatment of hygrom was carried out using conservative (puncture) and surgical methods. Results. Our experience showed that after a single puncture of the hygroma with the evacuation of its contents (10 patients), relapse developed in all cases. After repeated puncture of the hygroma in 10 patients with evacuation of the contents and subsequent administration of 0.5 ml of betaspan solution, 6 of them did not relapse within 5–6 months, but 4 patients had a relapse in the nearest period (1–2 months). Of the 23 patients who underwent surgery to remove the hygroma, 15 of them had no relapses. In 8 patients in the postoperative period, recurrent hygroma occurred, which could be explained by the ineffectiveness of eliminating the communication zone between the hygroma and the joint.Conclusions. For the successful treatment of this disease, it is important to understand that for the occurrence and development of hygroma, its communication with the joint cavity or tendon vagina is of great importance. In the absence of a message, the successful use of puncture methods of treatment is possible. In the presence of such a message and its detection during preoperative examination, surgical treatment should be planned with mandatory ligation of the leg of the hygroma.

Prognostic value of the Tokuhashi scale when choosing a method of surgical treatment of metastatic lesions of the spine

Introduction. Metastatic spinal lesion remains one of the most difficult problems of modern medicine. The purpose of treatment of patients with metastatic spinal lesion is to reduce pain, improve the quality of life, restore stability in the affected segment, prevent or reduce neurological deficits. In order to build the right treatment tactics, it is necessary to evaluate the prognosis of the life of a patient with spinal metastases before treatment.The study objective is to evaluate the prognostic significance of the Tokuhashi scale in patients with metastatic spinal lesion.Materials and methods. The study included 124 patients with metastatic spinal lesion operated in the spinal department in the period from March 2013 to July 2019 (64 (52 %) men and 60 (48%) women). The average age was 59 years and ranged from 18 to 78 years. The catamnesis ranged from 1 month to 6 years. 6 (5 %) spinal tumors were radically removed, palliative removal was performed in 77 (62 %) cases. In the remaining cases, 41 (33 %) underwent vertebroplasty. The mandatory diagnostic protocol of the preoperative examination included oncological status, clinical and neurological examination. The functional status of the patient was assessed on the Karnofski scale, life expectancy – on the Tokuhashi scale. In terms of preoperative examination, patients underwent computed tomography examination with intravenous contrast of three zones: the thoracic, abdominal cavities and pelvic region to determine the degree of dissemination of the process and, in some cases, to identify the primary focus. Currently, positron emission tomography is the optimal method of investigation at the preoperative stage. However, this method is not yet available in all clinics, so performing computed tomography scans of three zones is currently the optimal “gold standard” for examining this category of patients..Results. The life expectancy estimate was calculated for each patient according to the Tokuhashi scale (2005). Survival analysis was performed using Kaplan-Meier curves within the Tokuhashi prognostic groups. The median survival within the Tokuhashi groups was more than 3 years for the group of 12–15 points (life expectancy over a year), 14 months for the group of 9–11 points (life expectancy 6 to 12 months) and 7 months for the group of 1–8 points (life expectancy less than 6 months). The Cox model was used to identify factors related to survival.Conclusion. Determining the tactics of surgical treatment of a patient with a metastatic lesion of the spine is a complex and multicomponent question to which there is no unambiguous answer. A multidisciplinary consultation is currently the most adequate and reliable way to determine the treatment strategy for this category of patients. The use of the Tokuhashi prognostic scale is an additional effective tool for determining the life expectancy of patients with spinal metastases, and thus, in some cases, serve as the tool with which it is possible to determine the tactics of surgical treatment of patients.

Study of regularities of anatomical shape of eyeball at weak zinn support in patients with senile uncomplicated cataract

As experience shows, periodically after the planned cataract surgery with the implantation of an intraocular lens (IOL) into the capsule bag and uncomplicated course of the early postoperative period, there are cases of spontaneous dislocation of the "IOL – capsule bag" complex later. Their frequency is 0.2–2.8% of all cases of IOL dislocations. This is due to the initial weakness of the fibers of the zonule of Zinn, which was not detected during the preoperative examination. Purpose. To study the variants of the anatomical shape of the eyeball in patients with weak of the zonule of Zinn. Material and methods. The clinical material is presented by 30 patients with senile cataracts. Their ages ranged from 53 to 75 years old. The main group consisted of 15 patients with 1st degree lens subluxation. The comparison group included 15 patients without signs of weakness in zonule of Zinn support. The anatomical shape of the eyeball was evaluated. For this, the anteroposterior axis (APA) and transverse axis (TA) of the eyeball were measured, followed by calculation of the variant of the anatomical shape of the eye, using the assessment of options for the APA / TA ratio. Results. When using a comparative assessment of the values of the ratio APA / TA, a statistically significant difference between the groups of 1.10±0.04 versus 1.05±0.05 was revealed (Student's t test, p = 0.004). This indicates that the shape of the eyes in the form of a more elongated ellipsoid prevailed statistically significantly in the main group. Conclusion. The data obtained indicate an objective tendency towards the predominance of the anatomical shape of the eye in the form of a more elongated ellipsoid. It is possible that this fact is of clinical significance for the development of weakness of the zonule of Zinn support in the main group. Key words: the zonule of Zinn, weakness of the zonule of Zinn support, senile cataract, anatomical shape of the eye, anteroposterior axis of the eye, transverse axis of the eye.

MODERN PRINCIPLES OF DIAGNOSIS AND SURGICAL TREATMENT OF ISCHEMIC MITRAL INSUFFICIENCY

The purpose of the study is to evaluate and analyze the results of surgical treatment of patients with ischemic mitral insufficiency. Material and methods. The results of the examination and surgical treatment of 35 patients with ischemic mitral insufficiency are analyzed. In the operative period, in order to identify the degree of mitral insufficiency and the valvular apparatus, an echocardiography was performed, where the diameter of the fibrous ring, the interpapillary distance, the annulopapillary distance, the area of the cusp tension, and the depth of the coaptation of the valves were determined. Results. A preoperative examination proved the presence of mitral valve insufficiency with regurgitation of varying degrees. 15 patients underwent myocardial revascularization, 20 patients underwent myocardial revascularization + various options for correction of ischemic mitral insufficiency. After the operation, a significant improvement in the spatial-geometric correlation of the LV and mitral valve by reducing the tension forces acting on the valves and in the group of patients undergoing myocardial revascularization + various options for the correction of ischemic mitral insufficiency as the elimination of regurgitation. Conclusion. In patients with ischemic heart disease after echocardiographic studies, having determined the degree of mitral insufficiency with its moderate and severe degree, it is necessary to have a surgical correction of the mitral valve in its apparatus; the use of myocardial revascularization + various options for the correction of ischemic mitral insufficiency gives more tantalizing results than isolated myocardial revascularization.

Importance of postural change for accidental ingestion of dental prostheses: a case report

Accidental ingestion of dental prostheses requires immediate emergency action. The authors report a case of accidental ingestion of a dental prosthesis in a patient with a disorder of consciousness. The accidental ingestion was diagnosed by imaging examination, and the location of the dental prosthesis was explored under general anesthesia according to the preoperative examination images. However, no dental prosthesis was found in the hypopharyngeal region. The operators found a radiopaque region in the nasopharynx that was suspicious of a dental prosthesis by X-ray examination of the head and neck region. According to the X-ray examination, the dental prosthesis was removed from the nasopharynx. The patient’s postoperative course was uneventful. Postural change for cases of accidental ingestion of dental prostheses may be a simple and important lifesaving step in addition to traditional methods.

Optimization of the Algorithm for Choosing the Surgical Treatment of Anterior Recurrent Instability of the Shoulder Joint

Introduction. Chronic recurrent instability of the shoulder joint is a frequent outcome of conservative treatment oftraumatic dislocation of the shoulder (2.8–30 % of cases). Preoperative examination largely determines the outcome of surgical treatment of this pathology.The aim of the study was to provide a clinical assessment of the developed algorithm for the surgical treatment of patients with recurrent anterior shoulder joint instability. Materials and methods. The results of treatment of 98 patients with recurrent anterior shoulder joint instability were studied. Preoperative examination included clinical tests, MRI or CT with calculation of bone loss. Fifty-six patients (57.1 %) underwent Bankart operation, 14 patients (14.3 %) – Latarjet operation. Twenty-three patients (23.5 %) underwent Bankart + Remplissage surgery, and 5 (5.1 %) – Latarjet + remplissage. The result was assessed on the ROWE scale.Results. Bone defects significant in the formation of instability (“glenoid off track”) were found in 19.4 % of patients, and “glenoid on track” – in 80.6 %. According to the proposed algorithm for treating patients with anterior recurrent instability of the shoulder joint, the “glenoid off track” state was an indication for Latarjet surgery. When “glenoid on track” was used, indications for Bankart operation were displayed. The remplissage procedure was indicated in case of the presence of a Hill-Sachs grade 3 defect or the presence of hyperelasticity of the tissues of the shoulder joint. The mean ROWE score for the entire group of patients before surgery was 41.5 ± 12.8 points, and 15 months after sur gery – 94.9 ± 3.4 points. Two recurrent dislocations were revealed, one of which was associated with repeated trauma, and the other – with an incorrect choice of stabilization technique. One complication (axillary nerve neuropathy) was observed, which was arrested conservatively.Conclusions. The proposed algorithm allowed us to obtain positive results in 97.9 % of cases.

Neurological symptoms in Scheuermann’s disease: review of rare clinical observations

Neurological symptoms in Scheuermann’s disease are very rare, only a few dozen cases have been described. The main causes of spinal cord compression with the development of neurological symptoms in spinal deformities due to Scheuermann’s disease are compression by the anterior wall of the spinal canal, together with the dorsal leaflet of the dura mater, intervertebral hernia, and extradural bone cyst. The review provides a description of 38 clinical observations found in the literature. Compressing factors can also be spinal epidural lipomatosis and a displaced fragment of the annular apophysis. Scheuermann’s disease can be combined with syringomyelia. The magnitude of the kyphotic deformity does not correlate with the severity of neurological symptoms. Preoperative examination of a patient with Scheuermann’s disease should include methods that allow visualizing the condition of the spinal canal and its contents.
