The purpose of this study was to perform a systematic review and meta-analysis of randomized clinical trials (RCTs) investigating the efficacy of hilotherapy on postoperative pain, swelling, neurosensory impairment and patient satisfaction. The authors analyzed RCTs comparing the use of hilotherapy versus conventional cryotherapy or no cold treatment for orthognathic surgery and repair of facial trauma. The authors assessed the risk of bias and strength of evidence according to the Cochrane guidelines and GRADE rating system, respectively. Treatment effects were defined as weighted or standardized mean difference using the inverse variance method. Five RCTs were included. Postoperative pain and swelling in patients using hilotherapy were lower comparing to the control group in the postoperative day 2 (Pain: MD -1.75, CI 95% -2.69 to -0.81; Swelling: MD -21.16 mL, CI 95% -38.91 to -3.41) and in the final evaluation (Pain: MD -0.31, CI 95% -0.44 to -0.18; MD -4.45 mL, CI 95% -7.87 to -1.03). Patients reported higher satisfaction with hilotherapy, but no differences were found for neurosensory impairment. Current evidence suggests that hilotherapy is effective in reducing postoperative pain and swelling in orthognathic surgery and repair of facial fractures and may lead to improvements in patient satisfaction in the recovery phase.

A rare case of fracture of the coronoid process, sphenoid bone, zygoma, and zygomatic arch caused by a firearm is described. A 25-year-old man was hit in the face with a bullet, resulting in restricted mouth opening, difficulty chewing, and pain when opening the mouth. The clinical examination revealed a perforating wound in the right parotid region. A computed tomographic scan revealed a comminuted fracture of the left coronoid process with the bullet stopping in the intact left coronoid process. Treatment was bilateral coronoidectomy associated with speech therapy and was successful. Details of the clinical signs, computed tomography, treatment, and follow-up are presented.

Osteoma is an osteoblastic benign tumor characterized by the proliferation of either compact or cancellous bone. In the jaws, the most of cases reported in the literature presented as peripheral solitary lesions, involving preferably the posterior region of the mandible. However, central osteomas are quite rare, especially in the maxillary bone. The purpose of this article was to present the clinical, radiographic, surgical, and histologic features of a solitary central osteoma of the maxilla with involvement of the paranasal sinus and to review the literature for central osteomas located in the jaws. Our clinical report participates to literature as the 12th case of central osteoma in the jaws and the fourth case in the maxillary bone.
