RATIONALE/OBJECTIVE

Hemifacial spasm (HFS) is painless, paroxysmal, repetitive twitching of the unilateral facial muscle initially starting with the orbicularis oculi progressing to mid and lower facial muscles. This condition can be disabling and affect quality of life. Microvascular decompression (MVD) offers t he m ost permanent treatment and outcomes are measured through cessation of spasm. There are currently no Filipino-translated questionnaires to measure the quality of life (QOL) of patients with HFS. This study translated and validated the HFS-7 questionnaire and used it to assess and compare the preoperative and postoperative QOL of patients with HFS following MVD.

METHODS

The HFS-7 questionnaire was translated to Tagalog using a “forward–backward” translation method by 2 independent linguists. The translated questionnaire was validated by 4 expert neurosurgeons and were sent to 27 HFS patients to retrospectively assess pre-op and post-op QOL.

RESULTS

Twenty out of 27 HFS patients answered the survey. Majority of HFS patients were middle-aged females. The Criterion Validity Index (CVI) showed a result of 1 which indicates good validity of the translated HFS-7. It has good reliability with Cronbach alpha score of 0.97. T-test comparing the pre-op and post op scores showed that there is a significant improvement in QOL of HFS patients after MVD.

CONCLUSION

In patients with HFS, MVD offers an improvement of postoperative versus preoperative quality of life measurements. The Tagalog-translated HFS-7 questionnaire is a valid and reliable objective tool in measuring this treatment outcome.

Background and Objective: Neuroanatomy is both terrifying to learn and problematic to teach, and the different methods of neuroanatomical education have their own strengths and weaknesses. In this cross-sectional study, we evaluated the perception of undergraduate medical students towards the combined use of plastinated and formalinpreserved brain specimen in their neuroanatomy course. Methods: A bridging program was designed for students whose medical education was interrupted by the COVID-19 pandemic in order to reinforce the knowledge and understanding of anatomy that they acquired in a virtual environment. A total of 175 first year medical students participated in this learning activity, which included seven stations in neuroanatomy spread across two hours, and covered the anatomy of the circle of Willis, brainstem, cranial nerves, spinal cord, internal cerebrum, and external cerebrum. To evaluate short-term learning, the students were asked to take a quiz containing 10 multiple-choice questions before and after the learning activity. In addition, the students also answered a survey containing 11 Likert-type questions asking about their perception of the learningactivity. Results: Following the learning activity, mean test scores increased from 4.73 (SD 1.74) to 5.32 (SD 1.52; mean difference 0.59, p = 0.008). Majority of the students (mean 81%, range 43-93%) had a neutral or positive perception of plastinated brain specimen, and on factor analysis, plastinated brain specimen were found to be both practical and useful for learning neuroanatomy. However, the participants perceived plastinated brain specimen alone to be insufficient for learning neuroanatomy, and a multimodal approach to learning neuroanatomy is ideal. Conclusion Plastinated brain specimens were found to be an effective complement to formalin-preserved brain, and these should be used by medical schools when designing neuroanatomy learning activities for their students.
