BACKGROUND: Temporal hollowing is a common cosmetic complication following pterional craniotomies. To address this issue, we evaluated the efficacy of anterior rotation of the temporalis muscle at closure. Although this technique is not new and has been generally reported, no research studies have been conducted to evaluate its objective and patient-reported outcomes in the long term.
METHODS: We retrospectively reviewed 22 patients treated with pterional, fronto-orbitozygomatic, or frontotemporo-zygomatic craniotomies from March 2021 to 2023. A 12-month postoperative magnetic resonance imaging was used to evaluate the degree of temporal hollowing. To quantify temporal hollowing, we measured the distance of depression at the level of the temporal fossa. This distance, or "temporal thickness," was defined as the widest distance between the skull's outer cortical bone and skin surfaces at the level of the anterior clinoid process (D1) and foramen of Monro (D2). Furthermore, pre and postoperative cosmetic results were evaluated using the Rostock Functional and Cosmetic Cranioplasty (RFCC) Score. For reasons of objectivity, RFCC was tested by two independent plastic surgeons against the patient's rating.
RESULTS: After a year or more follow-up, 54.5% of patients exhibited no hollowing, while 31.8% had mild or moderate hollowing. Moreover, 91% reported good esthetic outcomes. No cases of severe hollowing were observed. Importantly, temporomandibular joint dysfunction was not observed.
CONCLUSION: These results suggest that anterior rotation of the temporalis muscle is an effective primary strategy to mitigate cosmetic deformities without compromising masticatory function. Further studies with larger sample sizes are warranted to confirm these findings.
