Maxillary osteosarcoma in a young patient undergoing postorthodontic treatment follow-up: The importance of ongoing oral examinations

Camouflage orthodontic treatment combined with genioplasty distraction osteogenesis for skeletal class II relationship secondary to osteosarcoma excision surgery

“…Patients have a life expectancy of more than 20 years after surgery, chemotherapy, or radiotherapy. In many cases, the systemic and local oncologic treatment, that saved the lives of these patients, is responsible for the adverse effects 3,5,6 . Dental and facial complications, which may occur months to years after the treatment of the patient is complete, are the main reasons for the patient visiting an orthodontist 7,8 .…”

“…HNO requires aggressive surgical management to attain negative surgical margins, chemotherapy, or radiotherapy to prevent local recurrence and metastasis, and bone grafting to restore function 3,4 . However, surgery and radiotherapy can cause oral problems such as jaw deformities, malocclusion, and/or temporomandibular joint disorders 5 . Therefore, orthodontic treatment may be recommended after the end of oncological treatment, and at least 5 years of survival without any oncological disease 6,7 .…”

Atypical Presentation of a Maxillary Chondroblastic Osteosarcoma and Complex Management

“…OS is histologically characterised by the presence of malignant and undifferentiated cellular stroma that produce neoplastic osteoid or primitive bone [1,4]. The histological subtype of OS is classified according to the predominant matrix material present, depending on whether it is osteoid (osteoblastic), cartilaginous (chondroblastic) or minimal matrix (fibroblastic) [10].…”

“…The early clinical presentation of craniofacial OS is usually non-specific and can delay the referral to a specialist [1]. August et al found that a painless swelling was the most common presentation amongst a series of thirty patients [7].…”

“…A sarcoma is a malignant mesenchymal tumour associated with varied clinical presentations and pathological classifications. In the craniofacial region rhabdomyosarcoma or osteosarcoma (OS) are most commonly seen [1]. OS makes up approximately 20% of all sarcomas and is the most common non-haematopoietic primary bone neoplasm, with a reported incidence of around 1 in 100,000 [2].…”
