Improvement of methods of treatment of odontogenic cysts of the jaws continues to be an urgent problem in surgical dentistry and maxillofacial surgery. Currently, the most promising is the use of multicomponent osteoplastic materials in order to optimize reparative osteogenesis after cystectomy for extensive jaw cysts. The aim of the study is to improve the method of cystectomy in the surgical treatment of large cysts of the upper jaw with osteoplasty of the bone defect with biocomposite materials in combination with the method of directed tissue regeneration. Clinical, radiological, histological. During the period 2015-2019, 54 patients with odontogenic cysts of the jaws were under observation, of which 12 were diagnosed as extensive. After cystectomy, the bone cavity was filled with biocomposite material: hydroxylappatite granules (Polistom, RF) in combination with PRP, on top of an autoplasma membrane isolated from PRP and collagen membrane. The immediate and long-term periods of treatment were quite favorable. Control X-ray examination after 12 months showed complete recovery of the bone defect with an organotypic structure in all patients.

Endodontic Retreatment

AbstractNon-surgical endodontic retreatment should always be the first option for reintervention when the initial endodontic treatment fails. The surgical treatment, called periradicular surgery, will be the procedure of choice when there is no success after the conventional endodontic retreatment. The purpose of this article is to describe clinical case of endodontic surgery, associated with guided tissue regeneration (GTR). A male patient, 24 years old, was referred for endodontic surgery on tooth 12 after two unsuccessful endodontic interventions. During the surgery, osteotomy, lesion curettage, apicectomy, retrograde obturation with Mineral Trioxide Aggregate (MTA), and filling of the bone failure with lyophilized bone and reabsorbable collagen membrane were performed. After six months of follow-up, the patient did not present any type of painful symptomatology. The endodontic surgery, associated with a technique of guided tissue regeneration, was efficient to solve this clinical case. Keywords: Endodontics. Apicoectomy. Guided Tissue Regeneration. Resumo O retratamento endodôntico não cirúrgico deve sempre ser a primeira opção de reintervenção quando o tratamento endodôntico inicial falha. Já o tratamento cirúrgico, ou cirurgia parendodôntica, será o procedimento de escolha quando não há sucesso após o retratamento endodôntico convencional. O objetivo deste artigo é descrever um caso clínico de cirurgia parendodôntica, associada à regeneração tecidual guiada (RTG). O paciente, gênero masculino, 24 anos, foi encaminhado para cirurgia parendodôntica no dente 12 após duas intervenções endodônticas sem sucesso. Durante a cirurgia foram realizadas manobras de osteotomia, curetagem da lesão, apicectomia, obturação retrógrada com Mineral Trióxido Agregado (MTA), além de preenchimento da falha óssea com osso liofilizado e membrana de colágeno reabsorvível. Após seis meses de acompanhamento do caso, o paciente não apresentou nenhum tipo de sintomatologia dolorosa. A cirurgia parendodôntica, associada à técnica de regeneração tecidual guiada, foi eficiente para solucionar este caso clínico. Palavras-chave: Endodontia. Apicectomia. Regeneração Tecidual Guiada.

Odontogenic cysts of the jaw are one of the most common diseases of the maxillofacial region, the main methods of treatment of which are cystotomy and cystectomy. Despite the widespread use of these surgical methods of treatment they are not without drawbacks. The presented clinical material shows the possibility of treating a patient with a large cavity formation of the jaw body by decompression drainage (marsupialization). The proposed surgical manual can be used either in isolation (the main method of treatment), or in combination with subsequent cystectomy. In modern domestic and foreign literature, publications devoted to this method of treatment of large and giant jaw cysts are rare, and therefore this clinical observation is presented.

Morphological Diagnosis

Ameloblastoma is a benign, locally aggressive tumour, with an unicystic variant that is very difficult to be differentiated from odontogenic cysts, because of their similarity in the clinical manifestation and X-ray examination. The morphological similarities between these processes make for a more difficult histological diagnosis. We present a case of a 32-year old male, admitted in the Maxillofacial surgery clinic in a University hospital for surgical treatment, because of a swelling in the left mandibular vestibule. A cystic formation, histologically diagnosed as an epithelial one, is removed. Eight months later, the patient is admitted once again, with the same symptoms. The biopsy result from the second operation is a plexiform unicystic ameloblastoma. What is being discussed is the connection between the two pathological processes and the difficulties with giving the correct morphological diagnosis.

In recent decades, we observed the displacement of bone grafts with new, diverse implantation materials, in particular on the basis of synthetic calcium phosphates. However, pure hydroxyapatites and tricalcium phosphates do not have osteoinduction properties. These circumstances led to the search for composite synthetic and composite materials based on biphasic ceramics using different biomaterials, binding components, bioactive substances, pharmacological preparations.The aim of the study – to improve the effi ciency of treatment of patients with odontogenic cysts, combining autologous bone marrow and artifi cial bone replacements, creating a mixture that, when it replaces bone defects, will optimize reparative processes.Materials and Methods. 82 patients aged 18–55 years who had been operated on the basis of radicular jaw cysts were examined. The patients were on inpatient treatment at the Department of Maxillofacial Surgery of Ivano-Frankivsk Regional Clinical Hospital. The results evaluation of the clinical study was performed according to the data of general-clinical, biochemical (free oxyproline, protein-bound oxyproline, aspartate-alanine aminotransferase), X-ray, echo-osteometric examination of patients. Clinical, radiological and echo-osteometric studies were performed prior to surgery and in 1,3,6, 9 and 12 months after surgical treatment.Results and Discussion. In all 3 groups of patients, the postoperative period ran with minor complications. The smallest percentage of infl ammatory complications in patients with the group III, in our opinion, can be explained by the anti-infl ammatory effect of the composite material created. The results of the ЕО of patients of the group III indicate that when performing postoperative bone jaws of the autologous bone marrow from Stimul-Oss there are active osteo-reparative processes with re-building and mineralization of the bone regenerate, since the velocity of passing ultrasound on the bone is the higher, the less its porosity and a higher concentration of calcium, phosphate and other mineral components.Conclusions. 1. The combination of artifi cial Stimul-Oss hydroxyapatite with an autologous bone marrow allows for a positive clinical outcome by strengthening the osteoconductive and osteoinductive properties of the newly developed combined graft. 2. The use of the newly created material does not affect the fermentation activity of the aminotransferase of the serum, indicating no negative effect on the patient’s body.

Focused Ultrasound Ablation

The purpose of this study is to evaluate the effectiveness of focused ultrasound (FUS) ablation as monotherapy for uterine fibroids in women planning a pregnancy. Of the 195 patients included in the study, long-term pregnancy occurred in 38. At the same time, immediately after FUS ablation, without prescribing additional methods of treatment, 7 patients became pregnant. Given the high frequency of additional surgical treatment methods (conservative myomectomy, hysteroresectoscopy), as well as additional procedures for FUS ablation, this method, despite its high efficacy in treating symptomatic myomas, cannot be recommended by us as the only treatment for uterine fibroids in women planning a pregnancy.

Methods Of Treatment

The purpose of the study was to analyze the data of modern domestic and foreign professional literature, which are devoted to new surgical methods of treatment of odontogenic cysts, to highlight the results of own clinical studies on the effectiveness of developed methods of cystectomy in jaw bones and their anesthesia. Materials and methods. Analytical and bibliosemantic methods were used in the research. The search for scientific information on medical topics for the period from 2010 to 2021 was carried out in the databases of electronic searching systems. Results and discussion. The use of standard techniques of conduction anesthesia of the trigeminal nerve is not always effective during cystectomy in the lateral parts of the mandible, due to the variability of branching of the trigeminal nerve, the possibility of additional innervation of the jaw branch from the superficial cervical plexus. Taking into account these anatomical factors, it is painless to perform a cystectomy of odontogenic cysts on the mandible. During oronasal cystectomy of odontogenic cysts that have grown into the nasal cavity it is advisable to block the nasopalatine nerve in the middle nasal passage. Modified methods of marsupialization can be used as an independent method of treatment of odontogenic cysts of large size, or be combined with radical removal of the cyst membrane. The use of ultrasound medical techniques reduces the risk of damage to adjacent soft tissues during enucleation of bone membranes in complex topographic and anatomical areas. The use of modern laser technologies and medical radiophysical equipment can increase the effectiveness of surgical treatment of odontogenic jaw cysts. The use of endovideosurgery techniques reduces the percentage of intraoperative complications. The introduction of computer spatial imaging of anatomical objects in dental practice has made it possible to develop new surgical technologies for precision-guided osteotomy and resection of the tips of the roots of masticatory teeth adjacent to the shells of radicular jaw cysts. Conclusion. In modern clinical practice, technical developments are used, which are based on the latest advances in laser optics, radio physics, bioacoustics, computer technology, which minimizes injuries during cystectomy operations, reduces the frequency of intraoperative complications. Individual-anatomical features of innervation of the maxillofacial area should be taken into account during local anesthesia, cystectomy and cystotomy operations in the jaw bones

Fibroblastic Activity

Glaucoma is a socially sensitive disease, being one of the leading causes of irreversible visual impairment and blindness. Refractory glaucoma is one of the most severe forms of the disease as it is resistant to conservative and surgical methods of treatment. Because of pronounced postoperative fibroblastic activity of eye tissues, leading to gross scarring and obliteration of outflow paths, modern materials and methods of drainage surgery are needed. The review presents a variety of drains used today and considers in detail their main characteristics and the biocompatibility of the material used with eye tissues. Various groups of implants are presented, whose effectiveness and safety are compared and assessed. The statistics of postoperative complications and long-term results of surgical treatment are given.
