Crushed ice was compared to continuous flow cold therapy for control of postoperative pain after arthroscopic patellar tendon autograft anterior cruciate ligament (ACL) reconstruction. This same sort of comparison can be made any maxillofacial surgeries with similar benefits. 

Surgical treatment and complications in patients with mandibular fractures leads to a significant degree of tissue trauma resulting in common postoperative symptoms and signs of pain, facial swelling, mandible dysfunction and limited mouth opening (truisms). This article abstract looks at the benefits of local cold treatment to postoperative swelling, pain and inflammation. 

Swelling, pain and trismus are undesirable consequences of impacted mandibular third-molar extraction. We looked at several authors who conducted a study to evaluate the effectiveness of cryotherapy, the therapeutic use of cold, in reducing undesirable consequences after surgery.
