• Example 1 The patient N., 34 years old, was hospitalized with an acute odontogenic localized osteomyelitis of the lower jaw adjacent to the 36 th tooth, complicated by the flegmon of the mouth floor, in overall fair conditions. After lancing and drainage on the day of hospitalization under general anesthesia of the left submaxillary and lower chin areas, MIKPOL No.1 was introduced into the suppurative necrotic nidus to fill half the volume of the cavity. A post-surgical wound was drainaged with two tubular double gap drainages. The bandaging that was done twice a day and the fractional wound wash was also completed via drainages using 0.02 % chlorohexedine.
• Example 2 Patient C, 33 years old, admitted with acute adenoflegmon of the right submaxillary area. Upon admission, a lancing and drainage of the adenoflegmon were conducted. Local treatment was carried out using MIKPOL No.2 that was administered to the post-surgical wound once a day to fill approximately half the volume of the suppurative cavity. Besides that, a general anti-bacterial and anti- inflammatory treatment was carried out. By the second day, a termination of the exudates processes and cleaning of the cavity from necrotic tissues were registered. The cytology study recorded a transition to the regenerative stage by the day 4 of the treatment, and then the traditional local wound healing remedies were commenced. The double reduction of the wound size to 5.99 cm 3 as determined by the planimetrical study, occurred by the day 5 of treatment. The secondary stitches were applied on the day 6 of the treatment.
• Example 3 The patient Sh., 41 years old, was treated for an acute odontogenic localized osteomyelitis of the lower jaw, complicated by the flegmon of the left submaxillary area. After a surgery with lancing and drainage, the local treatment was conducted with MIKPOL No.3. During bandaging that was conducted once a day, the pussy cavity was washed out with antiseptics via tubular drainage and the micro- granules were introduced to fill half the volume. By the next bandaging, the granules became swollen by absorbing the wound discharge. They were easily removed from the wound during bandaging when washing the wound with antiseptic via tubular drainage, after that a new portion of the MIKPOL was applied.
• Example 4 Patient Z, 30 years old. Admitted with a double-sided non-consolidate fracture of the lower jaw in the area of 36 th and 44th teeth complicated by the flegmon of the left submaxillary area. The lancing and drainage surgery were performed; the lower jaw was immobilized using Vasiliev's splints with inter-jaw rubber tug. The local treatment of the post-surgical wound was done using MIKPOL No.4, by filling half the volume of the suppurative cavity and applying an aseptic bandage. A bandage replacement frequency was once a day. As a result of the treatment, the exudative processes were suppressed by the day 3, whereas an infiltration of the soft tissues disappeared by the day 5.
• Example 5 The patient L, 30 years old, was treated for the acute odontogenic osteomielitis of the lower jaw adjacent to the 48 th tooth, complicated by the phlegmon of the moth floor. An excision surgery and drainage was conducted at the left and right submaxillary, sublingual and lower chin areas. During surgery the patient had an abundant malodorous gray pussy discharge. The soft tissues of the moth floor had necrotic alterations; there were indications of myocitis and fasciitis. With a background of general therapy, MIKPOL No.5 was applied locally by filling necrotic pussy cavities during bandaging that were performed twice a day after wound dialysis using antiseptics.
• the volume of the pussy cavity was determined planimetrically to be 41.6 cm 3 .
• the necrotic processes went into a recession, the wound has cleaned, and exudation processes halted.
• the tubular drainage was removed and the ointment bandages began to be applied locally.
• a cytology picture by the day 5 commenced to display the traits of regenerative process manifested by the macroscopic granulation.
• the volume of the cavities was 23.5 cm 3 .
• the early secondary stitches bringing together edges of the wound were applied. The patient was released for the outpatient treatment on the day 10 after the surgery.
