AB Lip  lacerations  may  result  in  significant  cosmetic  defects  if  not  properly  repaired.  The  lip  has  two  significant  anatomic  landmarks:  the  mucosal  border  (divides  intraoral  and  external  portions)  and  the  vermilion  border  (separates  the  lip  mucosa  from  facial  skin).  Meticulous  alignment  of  the  vermilion  border  and  its  associated  “white  line”  is  the  cornerstone  of  cosmetic  repair.  Lip  anatomy  may  be  distorted  by  the  kinetic  energy  of  the  impact  as  well  as  the  resultant  edema  surrounding  the  wound.  Lacerations  of  the  lip’s  vermilion  border  may  be  partial  or  full  thickness,  compromising  the  underlying  orbicularis  oris.
