AB Septal  hematoma,  with  or  without  abscess  formation,  is  an  uncommon  complication  of  septal  surgery  or  direct  nasal  trauma.  Bleeding  from  submucosal  blood  vessels  leads  to  an  accumulation  of  blood  between  the  mucoperichondrium  and  the  septal  cartilage,  which  may  lead  to  ischemic  avascular  necrosis  of  the  underlying  cartilage,  destruction  of  the  cartilage,  and  saddle  nose  deformity  (see  Fig.  1.30).  The  hematoma  and  any  necrotic  cartilage  may  then  serve  as  a  nidus  for  infection,  resulting  in  a  septal  abscess.  Chronic  cocaine  use  results  in  vasoconstriction  and  eventual  necrosis  of  the  septal  cartilage,  leading  to  perforation.
