ABSTRACT
Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.
ABSTRACT
<p><b>OBJECTIVE</b>To retrospectively investigate the effectiveness of sphenzygomatic suture as a guide in the reduction of zygomatic complex fracture.</p><p><b>METHODS</b>55 cases of zygomatic complex fracture classified according to Zingg classification were treated, sphenozygomatic suture in group 1 (n = 36) was reduced first, then the other fracture line was reduced, in group 2 (n = 19), malar bone was reduced according to superficial fracture line. Patients were followed up for 4 weeks to 3 months, aesthetic result and X-ray symmetry were observed.</p><p><b>RESULTS</b>All patients in group 1 were restored with satisfactory facial contour, 35 cases got precise reduction, 5 cases in group 2 were asymmetry.</p><p><b>CONCLUSION</b>During open reduction of complex zygomatic fracture, sphenozygomatic suture should be reduced at first as a guide, so as to get precise zygomatic complex reconstruction and normal aesthetic outcome.</p>
