- Abstract: Objective To investigate the anatomical foundation of endoscopic surgical approach of transmandibular angle to jugular foramen region.Methods Five wet cadaveric head specimens were collected and dissected through the endoscopic surgical approach of transmandibular angle to jugular foramen region.The relevant anatomical structures were observed and the depth and angle of operation were measured.Results A pedicled mandibular angle bone flap was formed by this surgical approach,and the length was(23.74±0.95)mm,the width was(18.95±0.56)mm.The operative depth after displacement of the mandibular angle bone flap was(8.54±0.55)mm,the operative depth after reduction of the mandibular angle bone flap was(24.94±0.90)mm,and the difference was statistically significant(P<0.05).The operative angle after displacement of the mandibular angle bone flap was(69.60±3.30)°,and the operative angle after reduction of the mandibular angle bone flap was(26.20±2.20)°,and the difference was statistically significant(P<0.05).Conclusion The endoscopic surgical approach of transmandibular angle to jugular foramen region forms pedicled mandibular angle bone flap,which can increase the operation angle,shorten the operation depth and improve the freedom of operation.This surgical approach is worthy of further study and discussion in clinical practice.
