Retro and prospective analysis of complex treatment of a patient with a polyostotic form of osteoclastoma of the maxillofacial region: clinical observation

In global literature there is not sufficient information on the course of the polyostotic form of osteoclastoma and methods of its treatment. For this reason, the analysis of this clinical case may be interesting for oncologists, maxillofacial surgeons and dentists of various specialties, who can reveal both the onset and recurrence of the disease. A characteristic feature of the course of this disease is the relapse of neoplasms with localization of foci in various parts of the upper and lower jaw. A clinical case of polyostotic form of jaw osteoclastoma and patient`s management tactics from 2006 to 2024 are described in the article. The disease was first diagnosed in 2006, when a neoplasm was revealed in the right part of the lower jaw. The neoplasm was removed by resection and mandibular defect was replaced by a carbon implant with further prosthesis. In 2011 a new neoplasm was detected on the left side in the frontal part of the upper jaw. At the same time a relapse of the disease was diagnosed with a new tumor focus in the lower jaw on the right. Surgical treatment was performed. Firstly, the neoplasm in the frontal area of the upper jaw was removed with replacement of the defect with a resection prosthesis. And secondly, a removal of the tumor on the lower jaw with resection of the chin within healthy tissues and replacement of the defect with an implant made of carbon-carbon material "Uglecon M" were performed. In 2023 the patient was invited to the dental hospital of the Clinical Multidisciplinary Medical Center of E.A. Vagner Perm State Medical University for dispensary observation and evaluation of the results of the treatment. The obtained results indicate the need for medical follow-up of patients after surgery for osteoblastoclastoma. The effectiveness of jaw implants made of carbon-carbon composite material " Uglecon M" was proved as well.
