Summary
The osteomyoplastic flap reduces cosmetic deformities after pterional craniotomy, though it takes longer. Both surgical approaches had similar complication rates for brain tumors and vascular conditions.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Craniofacial Surgery
Background:
- Pterional craniotomy can lead to cosmetic deformities, including temporal muscle atrophy and facial nerve damage.
- These deformities result from the surgical technique and post-operative muscle changes.
- Evaluating aesthetic and functional outcomes is crucial for patient satisfaction.
Purpose of the Study:
- To compare functional and aesthetic complications between classic pterional approach and osteomyoplastic flap.
- To assess patient-perceived outcomes in supratentorial surgical pathology.
- To identify the optimal surgical technique for minimizing post-craniotomy deformities.
Main Methods:
- Retrospective observational comparative study.
- Inclusion of patients undergoing pterional approach for supratentorial pathology (vascular or tumoral).
- Comparison between classic pterional approach and osteomyoplastic pterional flap.
Main Results:
- Osteomyoplastic flap resulted in significantly less perceived hollowing (p = 0.013).
- Classic pterional approach had significantly shorter surgical time (p < 0.001).
- No significant difference in the overall frequency of complications was observed.
Conclusions:
- The osteomyoplastic flap offers superior aesthetic results by reducing temporal hollowing.
- The classic pterional approach is associated with reduced operative time.
- Both techniques demonstrate comparable complication rates, making the choice dependent on prioritizing aesthetic outcomes versus surgical efficiency.
