Objective:To investigate the characters of skull osteoplasty under temporalis/outside temporalis by employing digital 3D titanium fiber mesh after standard large trauma craniotomy.Methods:Clinical data of 107 cases of skull osteoplasty under temporal muscle(55)/outside temporal muscle(52)by employing digital 3D titanium fiber mesh after 2~5 months postoperation were retrospectively analyzed

and compared according to operation condition(time

hemorrhage volume)

postoperative complications(postoperative subcutaneous hydrops

infection

postoperative hemorrhage

titanium mesh loosening)

and the postoperative subjective comfort level of the patients(shape abnormality

pain

chewing limitation).Results:The two operation methods had no obvious difference in operation time/hemorrhage volume.The outside temporalis group had obvious difference in postoperative complications(P<0.05).The under temporalis group were better than outside temporalis group in postoperative comfort level.Conclusion:The under temporalis skull osteoplasty by employing digital 3D titanium fiber mesh agrees more with the physiological structure

and has better functional recovery and higher patient satisfaction

so it better meets the clinical de.
