BACKGROUND AND OBJECTIVE

Awake craniotomy is often used in the surgery of glioma, the most common primary brain tumor. It has been proven to maximize the extent of tumor resection while minimizing post-operative neurologic deficits. Extensive research has been conducted on this topic, and we would like to perform a bibliometric analysis to identify the top 100 most cited articles in awake glioma surgery. Knowing the relevant and most impactful studies in the field would help clinicians streamline the evidence and determine its application in their practice.

METHODS

In October 2023, we performed a title-specific search on the Scopus and PubMed databases using (“glioma*” OR “astrocytoma*” OR “glioblastoma” OR “low grade glioma” OR “high grade glioma”) and (“awake craniotomy” OR “awake surgery” OR “awake brain surgery” OR “awake neurosurgery”) as our query term without any restriction criteria. The top 100 most cited articles were identified, reviewed, and analyzed.

RESULTS

Our search yielded a total of 5557 articles published. The top article had a citation count of 834 and reported on functional outcome after language mapping in glioma resection. Journal of Neurosurgery had the most number of publications. Neurosurgeons (n=81) were the primary author in most publications, followed by anesthesiologists (n=22) and neurologists (n=6). Three countries (USA, France, Italy) contributed to 74% of the articles. Most of the articles were reviews and case reports/series.

CONCLUSION

This study identified the top 100 most cited articles on awake glioma surgery. The content dealt with several aspects of awake craniotomy such as brain mapping, intraoperative techniques and adjuncts, and practice recommendations. This analysis can help identify knowledge gaps and potential areas of research in glioma surgery.

Objective: Neurosurgical boot camps allow trainees to hone practical skills in a risk-free environment, but the models and simulators used are relatively costly. In developing countries like the Philippines, low-cost alternatives have to be devised. The authors aimed to demonstrate the feasibility of using local, readily available, and inexpensive tropical fruits as surrogate models for basic neurosurgical skills training during a neurosurgical boot camp. Methods: Locally available tropical fruits were used to teach basic neurosurgical skills to trainees. Coconut, pomelo, and watermelon were used as models for head clamp application, scalp and dural suturing, and ventriculostomy, respectively. Feedback was obtained from the participants after the boot camp. Results: All eight residents thought that the boot camp was useful in learning new skills, and that the fruit models served their purpose. The trainees favored the fruit models that catered to the skill sets required according to level of training. The use of tropical fruits in the boot camp also provided an informal atmosphere that was conducive to learning. Conclusion The novel use of tropical fruits as surrogate models in basic neurosurgical skills training was a feasible and affordable alternative in resource-limited settings, although the activity was perceived to be more useful to junior than to senior residents. The informal atmosphere generated by the use of the fruits contributed to an improved learning experience for the trainee.
