AB ESSENTIALS  OF  DIAGNOSISEustachian  tube  dysfunction  and  middle  ear  barotrauma  are  the  2  most  common  complications  of  scuba  diving.ET  equalization  is  most  critical  while  approaching  close  to  the  water  surface  where  the  greatest  pressure  and  volume  changes  occur.Inner  ear  barotrauma  can  occur  via  2  mechanisms:  forceful  Valsalva  maneuver  in  an  attempt  to  equalize  middle  ear  pressure  with  ET  dysfunction  or  through  increased  pressure  differential  between  the  middle  ear  and  nasopharynx,  causing  the  ET  to  close.Alternobaric  vertigo  is  a  specific  type  of  inner  ear  barotrauma  that  occurs  when  there  is  a  pressure  differential  causing  asymmetric  stimulation  to  the  labyrinth.Differentiation  between  inner  ear  barotrauma  and  decompression  sickness  is  important  to  ensure  proper  treatment  to  prevent  permanent  sequelae.
