Our Experience Managing Difficult Accidental Chainsaw Trauma

Chainsaw and circular-saw injuries represent a rare condition within the maxillofacial region. The purpose of this clinical report is to describe the injuries and the clinical and surgical management of these rare traumas.

In this clinical report, 11 patients presenting themselves to the emergency room in the hospital "Policlinico Le Scotte," Siena, from March 2016 to September 2017 with severe chainsaw and circular-saw injuries, were included. All of the patients underwent general anesthesia and surgical treatment. This study describes 3 of the 11 patients with saw injuries.

No complications occurred during surgeries and a good primary closure of the wound margins were achieved in all patients. However, after surgery, the authors experienced some complications in 2 patients: the 1st one displayed chewing problems due to extensive local edema; the 2nd one developed a total loss of vision in his left eye, even though there was no damage inflected to the eye ball during the trauma or surgery.

All the patients were followed during the 1st year after surgery. The authors evaluated the patients at 3 months, 6 months, and after 1 year, and none of them developed complications or alterations related to the trauma. However, 1 patient is still experiencing loss of vision and he is under constant specialized follow-up.
