DOI : 10.5137/1019-5149.JTN.43674-23.1 AIM: To evaluate the effect of osteoplastic pterional craniotomy on temporal hollowing and its sequelae.

MATERIAL and METHODS: A total of 97 patients who underwent pterional craniotomy for an aneurysm were analyzed retrospectively. Of these 97 patients, 63 underwent surgery via the conventional pterional approach and 34 underwent surgery via the osteoplastic pterional approach. The temporal muscle volume was calculated bilaterally on CT images obtained in the sixth postoperative month. The results obtained in the conventional and osteoplastic approaches were compared.

RESULTS: Of the 97 included patients, 45 were female and 52 were male. The mean patient age was 50.37 years. In the conventional group, 31 were female and 32 were male. In the osteoplastic group, 14 were female and 20 were male. The temporal muscle volume difference between the operated and non-operated side was not statistically significant in the osteoplastic group. However, the volume was slightly lesser on the operated side than on the non-operated side in the conventional group.

CONCLUSION: The osteoplastic pterional approach is superior to the conventional approach in preserving the muscle volume and function. Patients who underwent osteoplastic craniotomy demonstrated higher levels of satisfaction with their facial appearance compared to those who underwent craniotomy using the conventional pterional approach.
