    A Rare Odontogenic Subperiosteal Abscess That Involved Entire Lateral Aspect of the Mandibular Body and Medial Aspect to the Level of Mylohyoid Ridge: Ultrasound Examination
    (Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology, 2023-02-28) Cherniak, Olha; Fesenko, Ievgen
    Management of odontogenic subperiosteal abscess (SPA) is one of routine procedures at daily oral surgery and dental practice. Typically, SPA is manifested as a one-side-of-the-jaw collection of purulent material between bony surface and periosteum. In contrast to the data published in numerous literary sources, we present a case reported for the first time in the English-language literature. A 42-year-old male patient with odontogenic SPA that involved two surfaces (aspects) of the mandibular body—lateral and medial aspect to the level of mylohyoid ridge—and inferior margin of the mandible is highlighted. Also, this article is designed to educate oral and maxillofacial surgeons on ultrasonographic possibilities for diagnostics of perimandibular subperiosteal infection highlighting an extremely rare case in the field.

    Management of the Bone Deformity Caused by Congenital Cyst of the Periorbital Area: Analysis of the Surgical Technique and a Short-term Outcome
    (Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology, 2023-03-31) Tymofieiev, Oleksii; Fesenko, Ievgen; Cherniak, Olha; Zaritska, Valentyna; Snisarevskyi, Pavlo; Shelest, Oksana
    The congenital periorbital cysts like dermoids/epidermoids, in rare cases, can require not only its’ excision but also correction/camouflage of the caused bone deformity. This management can require virtual surgical planning, osteotomy, and placement of the custom-made patient implant. In this report, the ultrasonography (USG) was proved as a highly effective imaging for the presurgical verification of the mass’s structure and establishment of the clinical diagnosis. The multi-slice computed tomography (MSCT), even on a two-slice MSCT machine, provided high-quality three-dimensional reconstruction of the area of bone deformation caused by the cyst and allowed for accurate surgical planning. A 20-year-old male patient with a congenital periorbital epidermoid cyst that led to the deformation of the lateral orbital rim was treated using the soft tissue volume-increasing technique for the correction of bone deformation following cyst removal. Analysis of the terminological diversity related with dermoid/epidermoid cysts is presented. Early diagnostics and management of congenital periorbital cysts can decrease the visual, orbital, and esthetic complications, as well as the need to perform bone reconstructive surgeries or other corrective surgical procedures.

    Suppurative mastoid lymphadenitis mimicking mastoiditis: a case report
    (Journal of the Korean Association of Oral and Maxillofacial Surgeons, 2021-10-31) Tymofieiev, Oleksii; Ushko, Natalia; Fesenko, Ievgen; Tymofieiev, Olexander; Yarifa, Maria; Cherniak, Olha
    Mastoid lymph node inflammation is a rare entity. Pathological conditions in the vicinity of the mastoid processes can be challenging for maxillofacial head-neck surgeons to address. We report a case of suppurative mastoid lymphadenitis in an 18-year-old Caucasian male. To our knowledge, there are no publications that highlight the clinical, ultrasonographic, intra-, and postoperative data for any pathologic process that presented as mastoiditis.

    Ultrasonographic Assessment of Masseter Muscle Region and Minimally Invasive Treatment of Post-Extraction Osteomyelitis
    (Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology, 2023-04-28) Tymofieiev, Oleksii; Fesenko, Ievgen; Cherniak, Olha; Serha, Olena
    Background: Mandibular osteomyelitis is commonly associated with invasive surgery and sequestrectomy. Here, we report a unique case in which it was possible to choose minimally invasive treatment during the exacerbation of osteomyelitis at the stage of sequestrectomy owing to the use of and correct assessment with ultrasonography (USG). This report aimed to present wide possibilities of USG for accurate diagnosis and minimally invasive management of chronic osteomyelitis. Case Presentation: A 50-year-old woman presented with significant swelling in the left masseteric region, trismus, and severe pain in the area of a previously extracted lower third molar. The imaging protocol included panoramic radiography, USG, and cone-beam computed tomography. Using USG, it was possible to identify the intermediate stage of abscess/phlegmon formation in the masseteric area, which would require an extraoral incision to drain the purulent focus. Conclusion: USG allows oral and maxillofacial surgeons to obtain a precise understanding of the condition of the tissues (e.g., bone surface, masseter muscle, subcutaneous tissue) and pathologic changes (e.g., periosteal reaction, bony defects) due to purulent processes in the area of the lateral mandibular ramus surface and surrounding soft tissues. The presence of purulent material and its motion on sonopalpation can be clearly identified using USG. Therefore, it is possible to plan for a less invasive surgical strategy.
