Clinical Features
Aetiologies of Hydrops with otosclerosis
Temporal bone studies
Investigations
Managements When to Operate
Post operative
Hydrops
Simulated Hydrops
frac14 patients have some dizziness
Most do not have endolymphatic Hydrops
Types of Dizziness
Vague or brief dizziness - resolves after stapedectomy
BPPV ndash improves after Epley manoeuvre and after stapedectomy
True Endolymphatic Hydrops
Post Operative Endolymphatic Hydrops With fistula
Delayed
Simulated Post-op Hydrops
Fluctuant hearing levels
Menierersquos disease like Vertigo attacks
Aural Fullness tinnitus
Possible Hennebertrsquos sign
Audiogram
2007 Anita Pollak Zurich ndash 2 bones with hydrops due to otosclerotic foci obstructing endolymphatic duct (ref 1)
1982 Johnsson et al ndash 4 temporal bones with cochleo-saccular hydrops at otospongiotic foci fluid dynamics disturbed (ref 2)
1984 Liston Paparella et al (ref 3)
1990 Yoon Paparella Schachem 4128 (3) temporal bones with otosclerosis involved VA and had hydrops 10128 (78) had hydrops (ref 4)
1990 H Fisch ndash hydrops due to capsular otosclerosis causing duct obstruction 18 other cases without hydrops (5) ref 5
Last 200 referrals with Otosclerosis
Presentation with clinical picture of associated Hydrops in 11 cases
Incidence at presentation = 55
No suggestive history ndash no need
Suggestive History
Electrocochleography (70-85 sensitivity 2002 Shea Ear Clinic) ( ref6 )
MRI Scan
Cutting edge inner ear MRI (ref 7) Japan
3 Tesla novel phase sequences after Gd
Otology amp Neurotology 2008 29(4)571-572 Active Otospongiosis amp Hydrops (ref8)
Dilated Saccule or Reissnerrsquos membrane in contact with footplate
Intraoperative or post operative rupture
Confirm with ECOG Treat Medically
Fluoride Low salt Possible Diuretics vasodilators or Dexametasone
Avoid Stapedotomy Hearing aid BAHA Consider Stapes surgery after 2 years if no symptoms and
ECOG returned to normal Only consider stapes surgery if audiogram favourablehellip
If surgery undertaken ndash Mobilisation or posterior 13 small fenestra
Poor cochlear function amp Good hearing in other ear
Bone conduction worse than 45dB at 500 Hz and high frequency loss (House group 1984) (ref 9)
Early ndash with Perilymph Fistula Leak rate too fast for replacement through cochlear
aqueduct Low CSF pressure syndrome E Hydrops Management ndash SURGERY to close fistula
Delayed Hydrops
Otospongiotic obstruction of VAELS Inner ear scar tissue ndash obstruction (eg Saccule collapse) Non-suppurative labyrinthitis causes altered fluid
production drainage (ref 10)
Simulated Hydrops
Piston abutting or adherent to saccule ndash vertigo but not hydrops (-ve ECOG)
Endolymphatic Hydrops occurs secondary to Otosclerosis in about 8 cases presenting for treatment
If the history is suggestive ndash Undertake ECOG
Avoid Stapes Surgery with genuine active hydrops
Post-operative Hydrops can develop due to fistulization ndash if so seal it
Delayed Post-op hydrops is also described and requires conservative management
