Except in some very rare emergency cases, episiotomies should never be performed. If your doctor performs routine or frequent episiotomies, then he may not be practicing up-to-date medicine. We have known since the mid-1980s that episiotomies are harmful and unnecessary except in a handful of rare emergencies, such as severe shoulder dystocia.

This doesn’t mean that you might not tear, but however badly you might tear an¬†episiotomy would’ve made things worse.
