The course of the new SARS-CoV-2 (COVID-19) is unpredictable and is still being investigated. Although the majority of complications are expected to affect the respiratory system, there have been reports in literature concerning the adverse effects of the infection on bone and joint tissue. Several complications have been observed in the maxillofacial area in people who suffered from the infection, including osteonecrosis and osteomyelitis of the jaw. These complications have been subject to various hypotheses. They may result either from the disease pathogenetic mechanism or from a response to the therapeutic modalities used to treat the underlying disease, and overuse of particular medications - glucocorticoids, antirheumatics, interleukin-6 inhibitors, and antibiotics. This article presents a case of osteonecrosis of the maxilla after severe COVID-19 infection.

Maxillofacial bone defects can have a profound impact on both facial function and aesthetics. While various biomaterial scaffolds have shown promise in addressing these challenges, regenerating bone in this region remains complex due to its irregular shape, intricate structure, and differing cellular origins compared to other bones in the human body. Moreover, the significant and variable mechanical loads placed on the maxillofacial bones add further complexity, especially in cases of difficult-to-treat medical conditions.

We present a case of a patient with HER-2 positive breast cancer who developed extensive areas of osteonecrosis in the mandible and maxilla due to the combination of trastuzumab, carboplatin, and docetaxel. The pathogenesis is discussed based on the literature.

Background: While the surgical treatment of mandibular stage 3 medication-related osteonecrosis of the jaw (MRONJ) is well-documented, research on maxillary stage 3 MRONJ is limited. Antiresorptive medications can induce MRONJ and atypical femoral fracture (AFF), but their impact on the feasibility of using fibula flaps for reconstruction remains controversial. This study aimed to assess the surgical outcomes and functional recovery of fibula flap reconstruction for maxillary stage 3 MRONJ, considering both recipient and donor site outcomes.

Introduction: Bisphosphonates (BPs) are widely used for osteoporosis and cancer-induced bone diseases due to their antiresorptive properties, yet they pose risks such as medication-related osteonecrosis of the jaw (MRONJ).
Methods: We present a unique case of concurrent oral squamous cell carcinoma (SCC) and MRONJ in a 72-year-old female chronically treated with oral ibandronate for osteoporosis. Following a dental extraction, she developed a nonhealing wound in the maxilla.
