Dirofilaria (synonym: threadlike worm) is a parasite of domestic and wild animals that can infect humans secondarily by mosquitoes. Our case is strictly demonstrating the features of the Dirofilaria repens located in the temporal area. And we precisely described that stage of absence of Dirofilaria migration as stage of anabiosis (state of greatly reduced metabolism) before its encapsulation stage.

A 49-year-old woman was referred to the maxillofacial surgery center with a gigantic mass (Panels A, arrow) in the right parotid area. Patient noticed mass`s appearance 3 years ago with painless rapid growth during last year. No loss of function of the facial muscles was noted. No pathologic lymph nodes were also noted clinically and on the multi-slice computed tomography (MSCT), which revealed a large mass with lobulated borders in the right parotid area, displacing masseter muscle and upper portion of the sternocleidomastoid muscle. Pre- (Panels B and D) and post-contrast (Panels C and E) MSCT was performed according to the radiological protocol. Axial scans of the contrast-enhanced MSCT (Panels C and E) clearly demonstrate the polymorphic structure of the mass helping establishing the diagnosis of parotid pleomorphic adenoma. Pleomorphic adenoma is a benign encapsulated tumor with a cellular polymorphism due to which this tumor is also named as a “mixed tumor.” Very often these tumors have incomplete/‘not true’ capsule with a finger-like extensions into the glandular tissue. This anatomical feature requires from the surgeons to avoid a tumor`s enucleation and perform the partial/total resection of the surrounding parotid tissue (parotidectomy) together with a mass. In cases of intratumoral localization of some branches of a facial nerve, the partial/total facial nerve sacrifice is indicated. Such a radical treatment helps to reach two tasks: to avoid recurrence and to avoid possible malignant transformation of the recurrent pleomorphic adenoma.

A 26-year-old male was transported to the hospital with a severe self-inflicted gunshot wound of the middle and lower face (Panel A) due to the suicide attempt. Three-dimensional computed tomography (CT) showed multiple site comminuted fracture of the facial skeleton including maxilla, mandible, right zygomatic, ethmoid, and nasal bones (Panel B). Also, the sockets of multiple avulsed teeth were noted. The patient was transported from the region several days after the injury. Due to the osseous and soft tissue loss, this type of gunshot wounds typically poses a considerable challenge to the oral and maxillofacial and plastic surgeons. Acute management in such cases includes resuscitative and life-saving measures. Timing of each surgical procedure should be chosen according to the patient condition, extent of the injury, and international recommendations.1 Operative principles include: (1) general considerations (all reconstructive options are to be taking into account, moreover, the volume of bone and soft tissue loss, functional and aesthetic purposes should be analyzed and planned very precisely), (2) skeletal fixation, (3) bone grafts, (4) soft tissue coverage, and even (5) a facial transplantation in some cases. In our case, the right eye enucleation (removal of the entire globe with all intraocular contents, while preserving orbital/periorbital structures) was done due to the severely ruptured globe. Typical indications for enucleation are severe eye trauma and blind, intraocular tumors, painful, and cosmetically disfiguring eyes. In case of evisceration the intraocular contents are removed from an intact sclera, extraocular muscle attachments and the orbital adnexa are preserved, with placement of an implant within the scleral shell with a purpose to retain orbital volume. Common indications for enucleation are unresponsive endophthalmitis and for improvement of cosmesis in a blind eye. The most common indication for orbital exenteration (removal of the globe and all orbital contents, including muscles, fat, optic nerve, lacrimal gland, nerves, periorbital bone, upper and lower lid complexes) is malignancy.

The aim of the study was to develop the method of quantitative evaluation of the platelets state in patient based on their aggregation and implement it to the medical practice. The method is based on analysis of the following parameters: strength of the created clot, its disaggregation and calculation of the quantitative index, i.e. platelet functional activity index (PFAI). Than authors evaluated the aggregation features of platelets by PFAI in combination with their quantitative content in peripheral blood followed by identification of normal, hyperactive and hypoactive platelet unit of hemostasis. Eventually, the new algorithm for plasma rich growth factors application was developed and implemented based on features mentioned above. It can be used for treatment of patients at the departments for maxillofacial surgery and dentistry, providing good or satisfactory results in the absolute majority of patients. Evaluation of platelet unit of hemostasis functional state based on PFAI provides the opportunity to standardize the platelet aggregation method. The suggested method is based on the biological principle of maintaining the most important constants of homeostasis and can be recommended for the development of more effective therapeutic approaches in clinical practice using the regenerative potential of platelets.
