Piezosurgery for intraosseous venous malformation of the mandible

Abstract

Intraosseous venous malformation of the mandible is rare. A 59-year-old woman was referred to our hospital for evaluation of a radiolucent lesion in the left body of the mandible that had been detected on a routine radiologic dental checkup. The patient wished for follow-up rather than operation. After 2 years’ follow-up, the radiolucent lesion had slowly grown, and the patient decided to have an operation. The lesion was removed surgically using the piezosurgery system, and conservation of the inferior alveolar nerve was achieved under general anesthesia. After operation, she reported an initial change in sensation (paresthesia). The sensitivity was recovered after 6 months. Patient prognosis has been good to date, with no symptoms indicating recurrence. We used to treat intraosseous venous malformations using the piezosurgery system. The present report describes a patient with intraosseous venous malformation of the mandible by complete excision and conservation of the nerve. It was useful to use piezosurgery for conservation of inferior alveolar nerve.

Intraosseous Venous Malformation of the Zygomatic Bone: Comparison between Virtual Surgical Planning and Standard Surgery with Review of the Literature

“…In the cases treated by our group, complete resection of the lesion was performed using piezoelectric scalpel to minimize bleeding due to the cavitation effect and to reduce the risk of associated lesion of the orbital content. The theoretical risk of soft tissue injury when performing complete resection is greater, although there have been no complications in the cases studied [ 36 ].…”

“…Reconstruction with autologous bone is commonly used. Calvarial graft (38%, five cases) [ 27 , 29 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ] and iliac crest (7.6%, one case) [ 1 , 46 , 47 , 48 , 49 ] are the two most frequent bone donor areas used; in the treatment of vascular malformations with the same location, rib (three cases) is the third most used autologous graft [ 50 , 51 , 52 ].…”

“…Outros estudos apontam para as vantagens da técnica piezocirúrgica as quais são: precisão no corte proporcionada pela micro-oscilação da peça de mão; corte seletivo efetivo no tecido ósseo mineralizado e proteção do tecido mole; grande variedade de pontas ativas as quais permitem a seleção da mais adequada para cada procedimento; sítio cirúrgico livre de sangramento oferecendo uma excelente visualização do campo operatório; cicatrização óssea mais rápida em comparação ao uso de instrumentos rotatórios [20][21][22][23][24][25][26] .…”
