Surgical osteoplasty and soft tissue excision as treatment for facial deformities in patients with renal osteodystrophy: three case reports.

Background: Renal osteodystrophy (ROD) may occur in patients presenting chronic kidney disease (CKD), leading to laboratory test alterations and changes in bone turnover with extra-skeletal calcifications. Treatment involves the medical management of secondary hyperparathyroidism, potential total parathyroidectomy, and surgical interventions concerning calcifications if causing facial deformities with esthetic and functional repercussions. In this context, the aim of the present study is to describe three cases of facial deformities caused by ROD treated through cosmetic-functional surgeries.

An Evaluation of the Efficacy of Local Hemostatic Measures in Dental Patients Taking Oral Anticoagulants: A Critical Review of the Literature Over the Past Two Decades.

The increased risk of bleeding observed in patients on oral anticoagulant therapy (OAT) undergoing outpatient oral surgical procedures has been reported in the literature and remains a major concern in the care of these patients. This is still of great concern to dental surgeons that discontinuing OAT medication increases the risk of thromboembolism, while maintaining the therapeutic dose increases the risk of hemorrhage. Several local hemostatic measures have been used to control bleeding in patients on OAT.

Severe maxillofacial renal osteodystrophy in two patients with chronic kidney disease.

Renal osteodystrophy (ROD) is the bone pathology that occurs as an uncommon complication related to the several alterations in mineral metabolism present in patients with chronic kidney disease (CKD). This paper describes two cases of severe ROD affecting the maxilla and mandible and causing facial disfigurement of a young and a middle-aged female patient with CKD. Both patients had a history of secondary hyperparathyroidism, previously treated by surgery.

Large solitary fibrous tumor of the oral cavity--report of a case.

The solitary fibrous tumor (SFT) is a rare soft tissue tumor with a substantially benign clinical behavior. The SFT of the oral cavity is a very uncommon entity. It is also of complicated diagnosis because of its extensive morphologic diversity and because of its similarity to many mesenchymal tumors.

Acute primary actinomycosis involving the hard palate of a diabetic patient.

Actinomycosis is a relatively rare infection caused by saprophytic bacteria of the oral cavity and gastrointestinal tract that can become pathogenic. The chronic hyperglycemia of diabetes mellitus induces events that promote structural changes in various tissues and are associated with problems in wound healing. This infection remains largely unknown to most clinicians because of its different presentations, and palatal involvement is extremely rare.
