Ruptured Eardrum: Symptoms, Treatment, Red Flags & Follow-Up

A ruptured eardrum is a discontinuity in the tympanic membrane—the thin fibrous layer that separates the external auditory canal from the middle ear. The pars tensa makes up most of the drum surface; the pars flaccida sits superiorly and is more susceptible to attic cholesteatoma when chronic suppuration persists, but day-to-day trauma usually breaches the tensa portion. Sound reaches the cochlea through ossicular vibration: a hole in the membrane uncouples that transformer mechanism just as fluid does, so patients perceive the same conductive dip seen in middle-ear effusion.

Perforations arise when rapid pressure gradients, infection-related ischaemia, or direct injury overcome tissue tensile strength. Traumatic causes range from cotton-bud or hairpin misadventure to acoustic blast, penetrating foreign body, skull-base fracture with haemotympanum, and barotrauma during diving or flying with blocked eustachian tube function. Infectious perforation most often punctuates acute otitis media when accumulated pus exceeds drum tolerance; the classic history is sudden pain relief coincident with warm, foul or bloody drainage. Iatrogenic perforation may follow misplaced suction, ear irrigation, or middle-ear surgery.

Once the barrier is lost, water and surface bacteria have a direct route into the middle ear—making keep-dry counselling as important as any drug. Spontaneous healing is typical when edges remain vascularised and inflammation settles, but smoking, ongoing infection, cholesteatoma, or large marginal defects shift the natural history toward chronic suppurative otitis media (CSOM) and need for tympanoplasty.

Presentation depends on mechanism. Traumatic perforation classically produces a sharp earache, brief hearing reduction, tinnitus, and sometimes blood-streaked discharge—occasionally a single episode of vertigo if the labyrinthine windows are disturbed. Infectious perforation is often heralded by bulging drum discomfort followed by sudden pain improvement when purulent material drains; parents describe a noticeable smell, stain on the pillow, or hearing that feels underwater. Low-grade fever may accompany bacterial middle-ear infection but is absent in many minor traumatic tears.

Typical features

• Sudden or stepwise conductive hearing reduction with otalgia or aural fullness.
• Otorrhoea—serosanguinous after trauma, mucopurulent when infection is driving the defect.
• Recurrent wicked tinnitus during active drainage.
• Mild water-triggered flare when non-potable fluid crosses the perforation.

Easy-to-miss or late patterns

• Painless chronic discharge with hearing drift—think CSOM or cholesteatoma rather than a “healed cold”.
• Delayed facial weakness ipsilateral to ongoing otorrhoea—needs same-day ENT, not outpatient watchful waiting.
• Bilateral symptoms after blast injury—document neuro status and consider basilar-skull work-up per trauma protocol.
• Asymptomatic perforation found on visa medical or employment screening—still requires counselling about water exposure.

Traumatic and barometric

Infectious

• Necrosis and perforation during acute otitis media when pus tension exceeds capillary perfusion of the drum.
• Chronic suppurative otitis media with granulation tissue and superinfection.
• Nasopharyngeal sepsis tracking via the eustachian tube in immunocompromise—lower threshold for culture-directed therapy.

Iatrogenic and postsurgical

• Microscopic clearance, pneumatic otoscopy overpressure, misplaced instrument during foreign-body removal.
• Myringotomy, tympanostomy tube placement, or staged tympanoplasty—patients should receive written expected healing timelines.

Risk amplifiers

• Previous perforation or tympanostomy—scarred drums are less elastic.
• Osteo-integrated hearing implants or prior mastoid surgery—local protocols define water restrictions.
• Occupational noise/blast exposure, contact sports without ear protection.
• Modifiable: discourage home canal instrumentation; reinforce swimmer/diver equalisation teaching.
• Fixed: craniofacial anomalies, eustachian tube dysfunction syndromes.

Diagnosis is fundamentally otoscopic, supplemented by audiometry when cholesteatoma, trauma, or occupational safety is in scope.

Clinical assessment

• Detailed mechanism: timing of barotrauma, penetrating object, assault, blast, recent URI, prior otic drops.
• Inspect the pinna and postauricular sulcus before the speculum—mastoiditis begins here, not on the drum.
• Describe the perforation: central vs marginal, approximate clock-face position, whether squamous debris or polyps cap the edges (suspicious for cholesteatoma).
• Use pneumatic insufflation only when licensed and when the clinical question warrants it—avoid forcing air through an acutely traumatised canal.

Laboratory and microbiology

• Swabs are not routine for first presentation; collect if CSOM fails to clear, immunocompromise exists, or hospital admission is needed.
• Blood cultures if systemically septic in tandem with extensive mastoid disease.

Audiometry and immittance

• Tympanometry may show flat middle-ear traces with large ear-canal volume—classic for patent perforation.
• Audiometry quantifies conductive loss; repeat after healing to document closure or plan surgery.

Imaging

• CT temporal bones when mastoiditis, cholesteatoma, or complications are suspected.
• MRI if lateral sinus thrombosis or intracranial abscess enters the differential.

Conductive hearing loss with discharge is not automatically a perforation—validate with a clean otoscopic field and think about mimics that change management or require different isolation and drops.

Uncomplicated traumatic perforations need analgesia, dry-ear discipline, and timed otoscopic review rather than automatic antibiotics. Layer antimicrobials only when acute middle-ear infection criteria are met, chronic drainage defines CSOM, or systemic sepsis develops; align with local ENT and antimicrobial guidelines.

First-line supportive care

• Scheduled weight-appropriate acetaminophen and/or ibuprofen when not contraindicated; avoid aspirin in children with viral co-infection.
• Counsel strict avoidance of swimming, diving, and soapy water in the canal; optional petroleum-coated cotton wool at the meatus for showers only if aligned with local ENT advice.
• Stop ototoxic otic drops unless an ENT specialist deliberately selects them and explains risk.

Antibiotics—when they help

• Acute perforation in the context of confirmed bacterial AOM → follow paediatric or adult AOM pathways; amoxicillin commonly remains first-line where local resistance patterns support it.
• Immunocompromise, toxic appearance, or failure of first oral course → escalate per sepsis bundle and specialist advice; consider parenteral therapy or broader coverage only with clear indication.
• Chronic suppurative otitis media with safe tympanic perforation → many ENT services prescribe topical fluoroquinolone drops (e.g., ofloxacin otic formulations) after assessment because they avoid aminoglycoside-related cochlear risk through the round window.

Second-line / procedural

• Paper-patch or fat-plug myringoplasty trials for selected non-healing central perforations—ENT-led.
• Formal tympanoplasty or mastoidectomy when cholesteatoma, mastoiditis, or large perforations preclude conservative healing.

Special populations

• Professional divers, pilots, musicians: earlier ENT and audiology review because livelihood hinges on barotrauma tolerance.
• Cochlear implant or hearing aid users: coordinate device downtime with audiology to prevent feedback trauma to the canal.
• Pregnancy: favour acetaminophen-first analgesia; involve ENT before any quinolone exposure.

• Document the defect once, document it well: size (rough %), position (clock-face), dry vs wet, blood vs pus, and whether the scutum or attic looks eroded.
• Time-linked review: otoscopy at 1–2 weeks for traumatic holes, sooner if pain escalates or discharge recurs; audiology at 8–12 weeks unless occupational rules dictate earlier testing.
• Medicines reconciliation: flag ototoxic systemic agents and ask specifically about over-the-counter neomycin or gentamicin drops.
• Antimicrobial stewardship: do not extend amoxicillin courses beyond guideline duration just because a small perforation remains visible—the healing metric is epithelial closure plus symptom control.
• Water restrictions: give verbal and written keep-dry advice; note exemption for chlorinated pool exposure only when ENT explicitly clears.
• Swim teaching & aviation: inform schools and occupational health nurses about interim limitations.
• MDT: ENT, audiology, microbiology when culture-directed therapy fails, trauma surgery when skull-base injury co-exists.

Early

• Persistent conductive hearing loss while the membrane granulates.
• Acute mastoiditis if infection tracks into pneumatised air cells—watch postauricular skin closely.
• Facial-nerve neuropraxia when inflammation encircles the horizontal segment.
• Suppurative labyrinthitis—severe vertigo with sensorineural deficit—needs emergency ENT review.
• Temporal bone fracture-associated CSF otorrhoea in trauma cohorts.

Late

• Chronic suppurative otitis media with permanent perforation.
• Cholesteatoma from retraction pockets harbouring keratin debris.
• Intracerebral abscess or lateral sinus thrombosis—rare but clustered with untreated mastoid sepsis.

Prevention is behavioural: coach patients never to insert cotton buds or improvised tools, wear hearing protection around blast risk, equalise gently during diving or ascent, and seek early URI care when eustachian tube dysfunction makes barotrauma likely. Maintaining pneumococcal and influenza vaccination schedules reduces suppurative middle-ear infections that perforate. Occupational health teams should screen workers with recurrent perforations for continued noise exposure compliance.

Small central perforations in healthy non-smokers frequently epithelialise within weeks to a few months when kept dry and infection-free. Marginal perforations, cholesteatoma, ongoing smoke exposure, or repeated water contamination push rates of non-closure higher and increase surgical referral. Even after anatomic closure, mild high-frequency hearing thresholds may lag—formal audiometry confirms functional recovery.

Triage and safety netting

Patients often believe a perforated drum is minor. Translate “keep dry” into concrete examples: no swim team, no sinus rinses that reflux into the ear, no unsupervised ear candles. Pair advice with written escalation triggers.

Procedure vigilance

Before any planned ear irrigation, verify drum integrity when history hints at prior perforation; if the view is incomplete, escalate to ENT rather than forcing fluid.

Pain and culture cues

Worsening otalgia after an initial improvement window suggests canal infection or developing mastoiditis—recheck temperature, inspect behind the ear, and notify the team early.

Documentation

Note laterality, mechanism, discharge character, analgesia given, safety-netting provided, and ownership of follow-up (GP, ENT, occupational health). Photographic consent policies vary by site—follow local governance.

While senior help is incoming: maintain airway if reduced consciousness, treat pain and fever per protocol, obtain large-bore access if septic, capture orthostatic vitals, and avoid further ototoxic ear drops unless explicitly directed.
