As for Galaxian Explosion, I don't think Shaka can stop it completly, because what we saw in OVA 8 when Saga used the attack, he didn't use his full powers in this attack because if he used his full powers I am sure the temple at least would be destroyed a little, but what we saw there!!

因为读者认为在处女宫时撒加没有完全地发挥此招的威力，如果撒加是完全用出这一绝招的全部威力，那么处女宫不会只毁坏一些部分（题外话：大家知道银河星爆是撒加的最大奥义，当星爆的威力达到顶峰时，可以毁灭银河里的星星，所以威力肯定不只这么一点，否则，原著作者车田也无需为星爆作此定义了）读者说他并没有看到处女宫有什么大的损坏。

Results:Before surgery, 39 patients with paroxysmal pain, after surgery, 84 patients with pain immediately disappeared, reaching 94.4%, 12 patients with mild throat discomfort, 2 patients with cough of short-term drinking water, 1 patient with hoarseness, the follow-up in the 3 months to restore Conclusion:Preoperative care focus on patients with Glossopharyngeal neuralgia are primarily on the preparation and pre-operative pain attack, as much as possible to avoid the attack of the pain, postoperative complications, mainly care, treatment and care through to complications as soon as possible.
