Germanicus Mirault was a French surgeon who pioneered cleft lip surgery.

Germanicus Mirault was born in Angers on either 29 February or 1 March 1796 (1796 was a leap year).

[2][4] Together with Joseph-François Malgaigne, Mirault introduced flap transposition for cleft-lip closure.

[5][6] In 1935, this work was championed by Victor Veau, who stated "Mirault is the genius of cleft lip surgery".

[7] He made other key contributions to maxillofacial surgical procedures, including the first ligature of a human lingual artery in 1833 and pioneering a method of temporary occlusion of the eyelids when correcting a post-burn ectropion, which is still in use today.
