Management
Treatment & repair
Give the window a chance to heal itself first; reach for surgery when it does not, or when hearing is slipping. The vertigo usually settles; the hearing is the gamble.
The two-stage approach
Most fistulae are first treated with rest and by avoiding anything that raises pressure in the head or ear. If symptoms do not settle — or hearing gets worse — an operation can find and seal the leak.
Start conservative: bed rest with head elevation, no straining, lifting or nose-blowing, and stool softeners — many traumatic fistulae heal within 1–2 weeks.1 Escalate to exploratory tympanotomy and tissue-graft repair for persistent or progressive disease.
Surgery both confirms and treats: inspect the round and oval windows and seal a leak with fat, perichondrium or fascia. Counsel realistically — vertigo responds more reliably than hearing, which may not recover and can deteriorate.2
The management ladder
Conservative care for everyone with stable hearing; surgical exploration and repair for failure or objective evidence; and honest aftercare.
Conservative — first-line
- Bed rest, head elevationReduce CSF/perilymph pressure surges; many traumatic fistulae seal spontaneously within 1–2 weeks.
- Avoid strainingNo heavy lifting, nose-blowing or Valsalva; stool softeners to prevent straining.
- Serial audiometryTrack the hearing — stability or improvement supports continuing conservative care.
Surgical — on failure or proof
- Exploratory tympanotomyRaise a tympanomeatal flap and inspect the round and oval windows for a leak.
- Tissue-graft repairSeal the leaking window with fat, perichondrium or temporalis fascia.
- IndicationsPersistent or progressive symptoms (especially deteriorating hearing) despite conservative care, or objective evidence of a fistula.
Aftercare & expectations
- Vertigo vs hearingVertigo responds to repair more reliably than hearing — counsel on a guarded hearing prognosis.
- RehabilitationVestibular rehabilitation for residual imbalance; avoid future barotrauma.
Start conservative when hearing is stable; escalate to exploration for failure of conservative care, progressive hearing loss, or objective evidence of a leak. The diagnosis is often only confirmed — or refuted — at the time of surgery.
The course over time
A typical course runs from a conservative trial, through reassessment, to exploration and recovery. Step through it:
Bed rest with head elevation, avoidance of straining, nose-blowing and heavy lifting, and stool softeners. Many traumatic fistulae heal spontaneously within this window.
Use vestibular rehabilitation for residual imbalance, and advise on avoiding future barotrauma. A post-stapedectomy oval-window fistula warrants prompt re-exploration rather than a long conservative wait.
Key points
- Conservative first — bed rest, head elevation, avoid straining; many heal in 1–2 weeks.
- Exploratory tympanotomy with tissue-graft repair for persistent/progressive disease or objective evidence.
- Surgery both confirms and treats the leak.
- Vertigo responds more reliably than hearing — counsel on a guarded hearing prognosis.
