Aggressive temporal lobectomy for uncal herniation in traumatic subdural hematoma
1Department of Surery, National Cheng Kung University Medical Center, Tainan, Taiwan, ROC.
Summary
Aggressive temporal lobectomy significantly improved survival and functional outcomes for patients with uncal herniation due to acute subdural hematoma, especially when complete resection was performed.
Area of Science:
- Neurosurgery
- Trauma Surgery
- Neurology
Background:
- Uncal herniation from fronto-temporal acute subdural hematoma presents a critical surgical challenge.
- Temporal lobe contusion and swelling often accompany this condition, complicating treatment.
Purpose of the Study:
- To compare the efficacy of aggressive temporal resection versus classic surgery for uncal herniation.
- To evaluate the impact of temporal lobectomy on patient survival and functional outcomes.
Main Methods:
- A retrospective study of 29 patients with uncal herniation treated surgically over 28 months.
- Group A (16 patients): Classic surgery (subtemporal decompression).
- Group B (13 patients): Aggressive temporal lobectomy (complete or anterior) plus decompression.
Main Results:
- Group A (classic surgery) had a 56% mortality rate and a mean Glasgow Outcome Scale (GOS) score of 2.2.
- Group B (aggressive resection) had a significantly lower mortality (1 death) and a higher mean GOS score of 4.0.
- Complete temporal lobectomy in Group B led to favorable recoveries, while anterior lobectomy resulted in poor outcomes.
Conclusions:
- Aggressive temporal lobectomy, particularly complete resection, offers superior survival and functional outcomes compared to classic decompression for uncal herniation.
- The extent of temporal resection is critical for achieving favorable results in these complex cases.
