I know only a few specialists in the world who can do it better than us.
Welcome! My name is Denys Valkevych.
I am the chief doctor of the Sirius-Dent clinic, a maxillofacial surgeon, an implant surgeon, and an orthopedic dentist.
Together with my team, we perform maxillofacial surgeries of any complexity, including removal of head and neck tumors.
We are ready to provide medical assistance to patients in the most difficult situations, even when «others refuse to help».
People We Can Help
We treat diseases and injuries of the maxillofacial area, as well as disorders affecting the head and neck in adults and children.
We perform all types of surgical interventions: from tooth extraction to complex reconstructive operations to restore the functions of the maxillofacial system and improve the patient’s appearance due to severe injuries or after treatment of oncological diseases.
Please contact us if you have faced any of the following problems:
- Occlusion disorders and chewing dysfunction
- Dental luxation (teeth displacement)
- Crunching, clicking in the jaw joints
- Pain when opening and closing the mouth or while chewing food
- Asymmetry of the face and other aesthetic defects of appearance
- Inflammation and suppuration of face and neck tissues
- Inflammation of the salivary glands
- Acute inflammatory process in the soft tissues of the jaw
- Complications after cosmetic procedures («beauty injections»)
- Formation of the false joint as a result of the lower jaw fracture
- Underdeveloped lower or upper jaw
- Bone tissue deficiency (for the installation of dental implants)
- Cysts of the jaw
- Head and neck tumors (benign or malignant)
- Open wounds, soft tissue damage of the face and neck, fractures of the facial bones as a result of an injury and other accidents
The operations we perform not only help to restore the functions of the maxillofacial system but also relieve the patients of complexes about their appearance. We are aimed at achieving aesthetic, natural-looking results, so most maxillofacial surgeries are real jewelry work.
In most cases, lack of timely treatment is the main reason the whole maxillofacial system as a functional complex may be disrupted.
Maxillofacial surgery in Ukraine used to be the prerogative of state dental institutes, but today the Sirius-Dent clinic is ready to offer an alternative at the European level. We constantly make sure that we have the most capacity in terms of technologies and equipment. The clinic’s medical support allows for operations of any complexity. Considerable attention is also paid to the service component, due to which the patients feel safe and comfortable.
Our doctors have extensive experience of working in the operating rooms, being constantly trained in the clinics of Germany and Lithuania. Due to the European methods of treatment, Sirius-Dent meets the generally accepted international standards. At the same time, our prices for maxillofacial surgery are lower compared to foreign clinics, so patients can get effective and high-quality medical care in Ukraine.
We are ready to provide medical assistance to patients in the most difficult situations, even when «others refuse to help».
- We conduct unique and rare operations
- We offer individually designed titanium structures
- We install the plates that dissolve independently and do not need to be removed
- We operate using unique equipment
- We use all the technologies of digital dentistry
- We give anesthesia drugs of the latest generation

We provide medical assistance to patients with oncological diseases of the head and neck by removing tumors and performing reconstructive operations – that is, we reconstruct what has been destroyed by the disease or lost during treatment.
A full range of surgeries for the treatment and restoration in the maxillofacial area:
Operations on the mucous membrane of the oral cavity in periodontitis
Recovery from fractures and dislocations of the jaw
Treatment of diseases of large and small salivary glands (sialadenitis)
Treatment of inflammatory diseases of the jaw bone (periostitis, osteomyelitis)
Treatment of jaw cysts
Increasing the volume of bone tissue for the installation of dental implants
Treatment of skeletal malocclusion
Treatment of dental injuries (fractured or displaced teeth)
Removal of ‘complicated’ wisdom teeth (displaced, those that have not fully or partially erupted into the dental arch)
Treatment of dystopia and retention of wisdom teeth
Fractures of the zygomatic complex
Correction of maxillofacial anomalies and orthognathic surgery (correction of the facial contours using a combined technique of orthodontics and surgery)
Exoprosthetics of maxillofacial defects
Plastic surgery of the ears (protruding ears, deformation of the auricles)
Fractures of the orbital walls
Surgery of tumors and tumor-like formations of the head and neck
Treatment of inflammatory diseases of the head and neck soft tissues (furuncles, abscesses, carbuncles, sialadenitis, lymphadenitis, phlegmons)
Maxillofacial Traumas and Surgeries after car Accidents
A separate area of our work is helping patients with maxillofacial traumas of various types and degrees of severity, including those with combined injuries. We restore the full function of a maxillofacial system and aesthetic appearance of the face. Sirius-Dent clinic surgeons have accumulated a lot of experience in soft tissue regeneration and facial reconstruction. Most operations are performed through internal access (oral cavity) without external incisions.
In the event of an injury, it is necessary to contact a maxillofacial surgeon as soon as possible, which increases the chances of a quick recovery.
Pediatric Maxillofacial Surgery
We have realized the dream of creating an ideal service to help children with maxillofacial injuries, as well as congenital and acquired facial anomalies.
- Injuries of the maxillofacial area
- Cleft of the upper lip and the palate
- Tongue tie (ankyloglossia)
- Lip tie (lip frenulum)
- Supplementary teeth (hyperdontia), the impacted teeth (those that have not erupted into the dental arch)
- Pierre-Robin syndrome
- Benign neoplasms of soft tissues and bones in the maxillofacial area
We have foreseen everything to perform operations and rehabilitation of small patients at a high level. In addition, we take care of the children’s psycho-emotional comfort – parents can be as close as possible to their child that needs support 24 hours a day.
Special attention is also paid to the Equipment for Pediatric Anesthesia. We have installed the modern machine – Dräger anesthesia workstation (Germany), which is the best and safest solution that the medical equipment market can offer today. We use a modern and effective system of postoperative analgesia, as well. We know by experience that if the children do not feel pain, they recover faster.

5 Advantages of Treatment in the Sirius-Dent Clinic
High International Standards of Treatment
The methods we use to treat pathologies of the maxillofacial area, head and neck meet high international standards. At the same time, the prices for surgery in the maxillofacial area at the Sirius-Dent are lower than in some European and American clinics. Our patients can undergo effective and high-quality treatment in their native country, without going abroad.
We can perform the most complex maxillofacial and reconstructive operations.
If hospitalization is required, the patients stay in the surgical department of our clinic, where all conditions for high-quality post-operative care are provided – intensive therapy, comfortable wards, round-the-clock monitoring by medical personnel.
Careful Preoperative Planning
At the Sirius-Dent clinic, we practice virtual surgery planning through 3D computer modeling of the maxillofacial skeleton based on CT images of the patient. Three-dimensional computer-assisted simulation allows seeing the final result before the operation. A virtual model of the patient’s skull from preoperative computed tomography scans helps to calculate each step of the surgical intervention. This technology significantly reduces the time of the operation and makes it more predictable.
Implementation of Multidisciplinary Approach
Our team includes an ENT surgeon, a traumatologist, a neurologist, a plastic surgeon and other related specialists who participate in the complex process of treatment of patients with combined injuries or disorders.
We have installed the modern machine – Dräger anesthesia workstation (Germany), which is the best and safest solution that the medical equipment market can offer today. It provides the pulmonary ventilation and monitoring of all important parameters in real time (cardiogram, oxygen consumption level, depth of anesthesia, and others). A team of experienced, highly qualified anesthesiologists works in the clinic, and only certified original drugs for anesthesia are used.
We have been working since 2004 and during this time we have helped thousands of patients with maxillofacial pathologies.
We can help you as well!
Advanced treatment technologies. Operations of any complexity. European treatment standards. Psychological comfort of patients.
What Is Important to Know
Preparation for Surgery in the Maxillofacial Area
The first stage of preparation for maxillofacial surgery is a consultation with a maxillofacial surgeon. Next, a person undergoes a standard preoperative examination and consults a narrow specialist who may refer the patient for further diagnosis related to the pathology (X-ray, CT, MRI).
At the second appointment, a maxillofacial surgeon studies the results of the patient’s examination and, if necessary, recommends consultations of other specialists (a neurologist, a therapist, and others) or additional examinations. Before the operation, the patient is consulted by an anesthesiologist.
Stages of Maxillofacial Surgery
Specific features of maxillofacial surgery vary depending on its type.
The main stages of restoration of the dentition integrity with the help of dental implants include bone surgery (mainly carried out in parallel with the installation of implants – titanium screws) and prosthetics (installation of a crown on the implant (carried out after a few months).
Surgical treatment of severe maxillofacial injuries is carried out in two stages. The first is the restoration of the integrity of soft tissues and the facial skull bones, application of cosmetic sutures. The second stage is corrective plastic surgery. The operation is carried out in a few months, if there are severe scars or facial asymmetry.
Rehabilitation after Maxillofacial Surgery
After minimally invasive maxillofacial surgery, the patient can leave the clinic in 40-60 minutes. If hospitalization is required, the patient stays in the clinic for no longer than three days.
In cases when the general condition of a patient is serious and, in addition to maxillofacial injuries, the brain contusion or other serious injuries are diagnosed, the duration of hospitalization may be 5-7 days.
Our patients stay in comfortable wards of the surgical department, where all conditions for high-quality post-operative care are provided.
What will happen if surgery is not performed?
If surgery for injuries of the maxillofacial area is not performed, the bones of the facial skull may grow together in the wrong position, which will lead to a clear asymmetry of face and distortion of its features. The lack of timely treatment in case of fractures of the articular processes of the jaw with displacement can lead to the invalidation (disability) of the patient, since he will not be able to open and close his mouth, as well as chew food. If the treatment of periostitis (inflammation of the periosteum of the tooth – the band of tissue that surrounds the bones) is not started in time, it will turn into osteomyelitis, and later into phlegmon – an acute inflammatory process in the soft tissues of the jaw which may be fatal.
What does a maxillofacial surgeon do?
A maxillofacial surgeon deals with the treatment of diseases and injuries affecting the face, head and neck. He carries out a surgical removal of flux (purulent inflammation around the tooth), performs bone surgery before tooth implantation, and treats inflammation of the salivary glands. The maxillofacial surgeon also performs reconstructive operations in the maxillofacial area after severe injuries or treatment of oncological diseases.
Can herbal medicine help with the head and neck tumors?
It is impossible to treat malignant tumors of the head and neck using herbs, as well as with the help of other methods of non-traditional medicine. The sooner a person seeks qualified medical care, the higher their chances of a full recovery. The only effective method of treating neoplasms of the head and neck is surgical removal.
Who is contraindicated to maxillofacial surgery?
The main contraindication to maxillofacial surgery is a serious condition of the patient, who is not allowed having general anesthesia. If the person undergoes a course of radiation therapy or chemotherapy, the operation is performed after the treatment is completed.

Treatment of Temporomandibular Joint Disorders
Crunching, clicking in the jaw joints, pain when opening and closing the mouth or while chewing food are the main symptoms of temporomandibular joint dysfunction.
The temporomandibular joint (TMJ) is responsible for the movements of the lower jaw, opening the mouth and closing the teeth.
The system of the jaw joints and surrounding muscles and ligaments as a functional complex may be disrupted. The development of pathology can be caused by occlusion disorders due to the following: the long-term absence of several teeth, tooth removal, elimination of dentition defects, wearing improperly made crowns or bridge-like prostheses, and injuries to the jaw.
Temporomandibular joint dysfunction can occur in adolescents during the formation of a permanent bite. In some cases, common joint diseases such as rheumatoid arthritis, arthrosis and others lead to the development of TMJ pathology.
If the cause of the joint disorder is abnormal occlusion, orthodontic treatment for the alignment of the dentition is carried out using bracket systems or other structures. The doctor may prescribe protective covers – special night-time mouthguards (capes) to not only reduce the load on the joint, but also prevent the teeth abrasion and get rid of unpleasant sounds. If the dysfunction caused the development of serious anatomical changes in the temporomandibular joint, it can be replaced with titanium prosthesis.
Treatment of Maxillary Sinus Diseases
As a rule, the main reason for the development of odontogenic sinusitis is the chewing teeth of the upper jaw affected by deep caries.
Sinusitis (maxillary sinusitis) can be either odontogenic or rhinogenic. Rhinogenic sinusitis develops when the infection enters the maxillary sinus through the nasal cavity. In this case, the condition is treated by an otolaryngologist. Odontogenic sinusitis is an inflammation of the mucous membrane of the maxillary sinus due to infection with pathogenic dental microflora.
Odontogenic sinusitis can also be caused by damage to the maxillary sinus floor area associated with careless tooth removal. If such a procedure has been carried out by an inexperienced or irresponsible physician, or in case the filling material gets inside the tooth hole, the inflammation of the mucous membrane of the maxillary sinus may occur.
In the treatment of odontogenic sinusitis, the source of infection is primarily eliminated. If this is an affected tooth that causes inflammation, it is removed. Then the cavity of the maxillary sinus is washed with a medicinal preparation (sanitation). The final stage of treatment of odontogenic sinusitis is the closure of the fistula at the site of the extracted tooth. For this purpose, bone surgery is performed.
Treatment of Salivary Gland Disorders (Sialadenitis)
Sialadenitis is an inflammation of the major or minor salivary glands.
There are two main reasons for the development of this disease: viral infection (the penetration of the virus into the gland) and bacterial infection (when the flow of saliva is blocked due to stones in the salivary duct).
In case of inflammation of infectious origin, antibiotics are prescribed for the treatment. With concrementous sialadenitis, stones are surgically removed from the ducts of the salivary gland. It is important, however, that the gland itself is mostly preserved and it continues to function normally.
Bone Surgery in the Maxillofacial Area
Bone surgery during dental implantation is performed to build up the bone in the place of a missing tooth.
In surgical dentistry, plastic surgery of bone tissue (sometimes mucous membrane) is most often performed during preparation for tooth implantation. After the tooth is removed, the bone tissue that helped it stay in the gingival socket does not receive the necessary load and gradually decreases in volume (atrophies).
The operation of bone tissue regeneration allows you to restore the volume of bone tissue necessary for the successful installation of dental implants. The patient’s own bone tissue or synthetic material can be used for bone augmentation (to build up the bone).
Bone surgery in the maxillofacial area can also be performed as part of reconstructive operations. For example, when a bone fragment of the facial skull is missing after injuries or cancer treatment. This leads to a clear asymmetry of the face and other serious aesthetic defects of the appearance.
We can restore the integrity of the facial skull bones in different ways: by transplanting bone blocks taken from other parts of the body or by installing titanium structures. They are designed for each patient individually based on CT images and then printed on a 3D printer.
Before the operation, a 3D computer simulation of the expected results is carried out – thus, the patient will be able to see how his appearance will change after surgery.
The most common causes of maxillofacial injuries in our patients are beatings and traffic accidents.
Recently, along with the growing popularity of electric transport, cases of falls from scooters have become more frequent, resulting in dissection of the chin and fractures of the articular processes of the lower jaw.
In the case of soft tissue injuries in the maxillofacial area, the first step is to stop the bleeding and suture the wounds.
If a fracture of the facial skull bone is diagnosed, the bone fragments are placed in the anatomically correct position and then they are fixed with the help of titanium plates or screws. Jaw fracture surgery is performed through internal access (in the oral cavity), without external incisions.
We try to restore the soft tissues and bones of the face after injuries in such a way that no scars remain as a result of the operation. But since in most cases injuries are accompanied by closed lacerations with uneven edges, it is not always possible to do this immediately. Therefore, after a few months, when the scar is fully formed, we perform plastic surgery aimed at scar correction.
Cheiloplasty (Plastic Surgery of the Lips)
Lip plastic surgeries in maxillofacial surgery are performed as part of reconstructive operations.
Indications for cheiloplasty in children are congenital pathologies – clefts of the upper lip, hard and soft palate («hare’s lip» and «wolf’s mouth»). For adults, cheiloplasty is performed to correct the consequences of injuries and surgical interventions. Another indication for surgical lip restoration is inflammation and suppuration of lip tissues after lip augmentation with low-quality drugs (including biopolymer gel).
Genioplasty (Chin Contouring)
Genioplasty (mentoplasty) is a plastic surgery aimed at correcting the size or shape of the chin.
The need for an operation usually arises in the case of malocclusion. Most often, its cause is the underdevelopment of the lower jaw, which manifests itself externally in the form of a disproportionately small chin, which distorts the face profile.
Before surgical correction of the bite, the patient undergoes orthodontic treatment using bracket systems or other structures. If, after its completion, the size of the chin remains insufficient, then an operation (orthognathic surgery) is indicated.
Chin augmentation surgery (volumization of the jawline) can be done in two ways. The first involves bilateral dissection of the jaw bone in the projection of the 7-8 teeth and moving it forward. In the second method, the chin is enlarged by cutting out a fragment of the chin bone on the front of the jaw, moving it forward, and fixing it in a new position or installing a silicone implant on the periosteum. As a result, surgical orthodontics allows you to correct the bite, as well as to restore facial symmetry and harmony.
Cheekbone Plastic Surgery
Plastic surgery of the cheekbones (malarplasty) is indicated for deformation or asymmetry of the cheekbones due to injuries.
During the operation, individually designed prostheses made of titanium are used, which are installed on the cheekbones.
Plastic Surgery of the Ears
Ear plastic surgery is performed for the purpose of correcting protruding ears, deformation of the auricles and other ear deformities, as well as eliminating the effects of inflammatory processes and reconstructing after removal of neoplasms.
The possibilities of modern surgery allow us to help patients who do not have an auricle. In such cases, silicone prosthesis is manufactured and installed, completely replicating the shape and color of a healthy ear. At the Sirius Dent clinic, earlobes can be sutured after wearing earrings and “tunnels”.
The operation is minimally invasive and will be performed under sedation.
