Abstract
PURPOSE
Osteoradionecrosis (ORN) of the jaw is a severe and debilitating complication of the head and neck radiotherapy which frequently occurrs after oral surgery. This clinical audit aims aevaluate the effectiveness of combined use of pentoxifylline and tocopherol (PENTO) in prevention ORN onset in patient who underwent oral surgery after head and neck radiotherapy (RT).
MATERIAL METHOD
In this clinical audit Pentoxifylline 400 mg, twice a day, and Tocopherol 800 IU once a day (PENTO protocol) have been prescribed. Patients started the protocol 1 week before the surgical procedure and continued for 8 weeks after.
RESULTS
Twenty-nine patients were included. They received 75 surgical interventions under PENTO protocol: 71 surgical procedures of dental extraction (single or multiple dental extractions in each session) and four implant placements. A total of 152 dental extractions were carried out: 64 surgical extractions which required the raising of mucoperiosteal flap, and 88 simple extractions. Four out of 29 patients developed ORN after surgical procedures: four cases of ORN occurred after dental extractions (5.6%) and one case of ORN after implant placement (25%).
CONCLUSION
PENTO is a useful ORN preventive protocol, low-cost and clinically feasible, safe and well tolerated by patients. Further studies should focus on better defining the effectiveness PENTO, independently from the antibiotic therapy.
