▁The ▁or bits ▁are ▁then ▁mobil ized ▁and ▁brought ▁towards ▁each ▁other . ▁Because ▁this ▁often ▁creates ▁excess ive ▁skin ▁between ▁the ▁or bits ▁a ▁mid line ▁exc ision ▁of ▁skin ▁is ▁frequently ▁necessary . ▁This ▁approxim ates ▁the ▁e y eb rows ▁and ▁eye ▁corners ▁and ▁provides ▁a ▁more ▁ple asing ▁look . ▁ ▁Fa cial ▁b ipart ition ▁The ▁standard ▁procedure ▁( box ▁o ste ot omy ) ▁was ▁modified ▁by ▁Jacques ▁van ▁der ▁Me ulen ▁and ▁resulted ▁in ▁the ▁development ▁of ▁the ▁fa cial ▁b ipart ition ▁( or ▁median ▁fa ci ot omy ). ▁ ▁Fa cial ▁b ipart ition ▁first ▁involves ▁splitting ▁the ▁front al ▁b one ▁from ▁the ▁sup ra orb ital ▁rim . ▁Then ▁the ▁or bits ▁and ▁the ▁mid face ▁are ▁released ▁from ▁the ▁sk ull - base ▁using ▁mon ob lock ▁o ste ot omy . ▁Then ▁a ▁tri angular ▁sh aped ▁piece ▁of ▁b one ▁is ▁removed ▁from ▁the ▁mid line ▁of ▁the ▁mid face . ▁The ▁base ▁of ▁this ▁tri angular ▁segment ▁lies ▁above ▁the ▁orb ita ▁and ▁the ▁a pe x ▁lies ▁between ▁the ▁upper ▁in cis or ▁teeth . ▁After ▁removing ▁this ▁segment ▁it ▁is ▁possible ▁to ▁rotate ▁the ▁two ▁hal ves ▁of ▁the ▁mid face ▁towards ▁each ▁other , ▁thus ▁resulting ▁in ▁reduction ▁of ▁the ▁distance ▁between ▁the ▁or bits . ▁It ▁also ▁results ▁in ▁level ing ▁out ▁the ▁V - sh aped ▁max illa ▁and ▁therefore ▁w iden ing ▁of ▁it . ▁ ▁Because ▁hy pert elor ism
