🎧 FREE MSRA PODCAST – Presbycusis (Age-Related Hearing Loss): Causes, Diagnosis & Management

Explore presbycusis—the most common cause of hearing loss in older adults. This high-yield revision episode covers the underlying causes, clinical features, diagnosis, management, and the wider impacts of age-related hearing loss. Essential listening for exam revision or practical ENT knowledge!

🧠 Key Learning Points

Definition
• Presbycusis = progressive, bilateral, sensorineural hearing loss due to ageing
• Affects high-frequency sounds first; gradual onset

Causes & Risk Factors
• Natural ageing of the auditory system
• Family history and genetic predisposition
• Lifetime noise exposure (occupational, recreational)
• Cardiovascular disease, arteriosclerosis
• Diabetes (accelerates vascular damage)
• Smoking
• Ototoxic drugs (e.g. aspirin, some chemotherapy)
• Oxidative stress

Pathophysiology
• Degeneration of cochlear hair cells (especially high-frequency)
• Atrophy of auditory nerve fibres
• Reduced blood supply to inner ear structures

Symptoms
• Difficulty hearing high-pitched sounds
• Trouble understanding speech, especially in noisy places
• Need to increase TV/radio volume
• Speech sounds muffled/distorted
• Tinnitus (ringing/buzzing)
• Rarely, hyperacusis (increased sensitivity to sound)

Diagnosis
• Clinical: History, otoscopy (usually normal)
• Audiology: Pure tone audiometry (high-frequency sensorineural loss), speech audiometry
• Tympanometry (normal in presbycusis)
• Blood tests only if another cause suspected
• Rule out: conductive causes (wax, middle ear disease), central processing issues

Management
• Hearing aids (mainstay)
• Assistive listening devices (amplified phones, TV systems)
• Communication strategies (face-to-face, clear speech, minimise background noise)
• Auditory rehabilitation and support
• Cochlear implants for severe/profound cases
• Manage modifiable risk factors (cardiovascular health, noise exposure, avoid ototoxins)

Complications
• Social isolation and withdrawal
• Depression, anxiety
• Communication difficulties affecting relationships and work
• ↑ Risk of falls and accidents
• Reduced quality of life

⚕️ FREE MSRA PODCAST – Post-nasal Drip
🎧 A clear, high-yield breakdown of this common cause of chronic cough and throat clearing – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Post-nasal drip (PND) is the sensation of mucus dripping from the nose or sinuses into the throat, typically due to excess mucus production or impaired drainage.

📌 Causes & Risk Factors
• Allergic rhinitis
• Sinusitis (acute or chronic)
• Upper respiratory tract infections
• Gastroesophageal reflux (GERD)
• Environmental irritants – smoke, dust, pollution
• Medications (e.g. antihypertensives)
• Nasal structural abnormalities
🧠 Mnemonic: “AIR GEMS” – Allergies, Infections, Reflux, GERD, Environment, Meds, Structure

📌 Pathophysiology
• Inflammation increases mucus production
• Impaired ciliary clearance leads to mucus accumulation
• Mucus drips posteriorly, triggering cough and throat irritation

📌 Symptoms
• Sensation of mucus in throat
• Frequent throat clearing
• Chronic cough, often worse at night
• Sore throat, hoarseness
• Sometimes halitosis or nasal congestion
🧠 High-yield symptom combo: chronic cough + throat clearing

📌 Differential Diagnosis
• Asthma
• Chronic bronchitis
• Laryngopharyngeal reflux (LPR)
• Persistent upper airway infections

📌 Diagnosis
• History and clinical examination
• Inspect nasal mucosa, posterior pharynx
• Imaging (e.g. sinus X-ray or CT) if structural cause suspected
• Allergy testing if allergic rhinitis is likely

📌 Management
• Identify and treat underlying cause

• Antihistamines & nasal corticosteroids for allergies

• Antibiotics for confirmed bacterial sinusitis

• Proton pump inhibitors if GERD-related
  • Saline nasal irrigation – helpful across all causes
  • Avoid environmental triggers
  • Surgery only for refractory structural problems
  🧠 Tailor treatment based on cause – not one-size-fits-all

📌 Complications
• Rarely from the drip itself
• Untreated underlying cause may lead to:

• Chronic cough

• Laryngitis

• Secondary sinus infections

• Worsening asthma

📌 Prognosis
• Excellent if the underlying issue is addressed
• Chronic cases (e.g. allergies) may need long-term management

⚕️ FREE MSRA PODCAST – Peritonsillar Abscess (Quinsy)
🎧 A clear, high-yield breakdown of this painful ENT emergency with pus and a hot potato voice – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Peritonsillar abscess (Quinsy) is a collection of pus in the peritonsillar space, outside the tonsil capsule but within the soft tissues of the oropharynx.
• It’s usually a complication of untreated or severe tonsillitis.

📌 Causes & Risk Factors
• Common pathogens: Group A Streptococcus, Staph aureus, anaerobes, occasionally Haemophilus and viridans streptococci
• Recurrent tonsillitis
• Previous Quinsy
• Inadequately treated throat infections
• 15–30 age group most affected
• Smoking and immunocompromised states increase risk
🧠 Mnemonic: “STREP-T” – Strep, Tonsillitis (recurrent), Recurrence history, ENT age group (15–30), Poor immunity, Tobacco

📌 Pathophysiology
• Begins as tonsillitis, infection spreads into the peritonsillar space
• May also originate from Weber glands (minor salivary glands) near the upper tonsil
• Inflammation and pus accumulate, forming an abscess
• May progress from cellulitis to abscess

📌 Symptoms
• Severe unilateral sore throat
• Painful swallowing (odynophagia)
• Hot potato voice (muffled speech)
• Trismus (difficulty opening mouth)
• Fever, malaise, earache, drooling, fetid breath
• Displaced uvula – pushed away from swollen side
🧠 Mnemonic: “HOT PUSt” – Hot potato voice, One-sided pain, Trismus, Pus (abscess), Uvula shift, Sore throat

📌 Differential Diagnosis
• Acute tonsillitis
• Epiglottitis
• Retropharyngeal abscess
• Ludwig’s angina
• Lymphadenopathy
• Infectious mononucleosis

📌 Diagnosis
• Mainly clinical – history and classic signs (unilateral sore throat, uvula deviation, trismus)
• Throat swabs, FBC, CRP
• Ultrasound to differentiate cellulitis vs abscess, guide drainage
• CT neck only in atypical or severe/deep spread cases
• Consider monospot test if EBV suspected

📌 Management
• Supportive care: IV fluids, strong analgesia
• IV antibiotics: Broad-spectrum (e.g. clindamycin, ampicillin-sulbactam)
• IV steroids: Single dose may reduce swelling and pain
• Surgical drainage:
– Needle aspiration
– Incision and drainage (I&D)
– Quinsy tonsillectomy (select cases)
• Ultrasound guidance useful if aspiration fails
• Interval tonsillectomy considered for recurrent episodes
❗ Same-day ENT referral is essential if suspected

📌 Complications
• Recurrence
• Deep neck space infection
• Necrotising fasciitis
• Airway obstruction
• Aspiration pneumonia, sepsis
• Lemierre’s syndrome – IJV thrombophlebitis with septic emboli
• Mediastinitis, massive haemorrhage (rare but life-threatening)

📌 Prognosis
• Excellent with early drainage and IV antibiotics
• Delayed treatment increases risk of serious complications
• Interval tonsillectomy prevents recurrence in high-risk patients

⚕️ FREE MSRA PODCAST – Perforated Tympanic Membrane
🎧 A clear, high-yield breakdown of this common ENT condition – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• A perforated tympanic membrane (aka ruptured eardrum) is a hole or tear in the eardrum, the membrane separating the outer and middle ear.
• Leads to hearing loss and increased risk of middle ear infections.

📌 Causes & Risk Factors
• Most common cause: Middle ear infection (acute otitis media)
• Trauma – e.g. cotton bud injury
• Barotrauma – from flying or diving
• Acoustic trauma – loud noises
• Spontaneous rupture
• Risk factors:

• Cotton bud use

• Recurrent infections

• Loud noise exposure

• Scuba diving / flying

• History of ear surgery
  💡 Mnemonic: “POP EAR” = Pressure, Otitis media, Poke, Exposure (noise), Altitude, Rupture

📌 Pathophysiology
• Eardrum disruption leads to:

• Loss of sound vibration → conductive hearing loss

• Entry point for pathogens → risk of infection
  • Direct connection forms between external canal and middle ear

📌 Symptoms
• Ear pain
• Hearing loss
• Otorrhea (discharge)
• Tinnitus (ringing)
• Vertigo (sometimes)
• Visible perforation on exam
💡 Classic case: Sudden hearing loss + ear discharge after infection or trauma

📌 Differential Diagnosis
• Otitis media (with/without perforation)
• Otitis externa
• Middle ear effusion
• Earwax impaction
• Always perform otoscopy to confirm

📌 Diagnosis
🔍 Otoscopy – visualises perforation
🎧 Audiometry – assesses hearing levels
📊 Tympanometry – tests middle ear pressure and movement
🖼️ CT scan – only if complications suspected
💡 Key tip: Always examine the ear – diagnosis is visual

📌 Management
🩺 Conservative (majority):
• Most perforations heal within 6–8 weeks
• Avoid water in the ear during healing
💊 Antibiotics – only if underlying infection present
🔧 Surgical (if not healing):
• Myringoplasty – surgical closure of eardrum
💡 Core plan: Watch, protect from water, intervene if persistent

📌 Complications
• Chronic or recurrent otitis media
• Persistent hearing loss
• Cholesteatoma – abnormal skin growth in middle ear
• Tympanosclerosis – scarring of the membrane
• Rare: Injury to ossicles or facial nerve
💡 Prevention = avoid moisture, follow up for healing

📌 Prognosis
• Generally excellent
• Most cases heal spontaneously
• Outcome depends on size/location, presence of infection, and patient factors

✅ MSRA Deep Dive: Parotid Gland Tumours
In this ENT-focused episode, we walk through your revision notes on parotid gland tumours, highlighting the must-know features, red flags, and complications. Whether you're revising for the MSRA or refreshing your understanding of head and neck lumps, this episode breaks down the condition into a high-yield, exam-friendly framework.

🧠 Key Learning Points

📌 Definition
Parotid gland tumours are abnormal growths in the largest salivary gland (located near the ear). Tumours may be benign or malignant, and classification is vital for management.

📌 Rule of 80s
• 80% of salivary gland tumours occur in the parotid
• 80% of those are benign
• 80% of benign ones are pleomorphic adenomas
💡 A powerful memory hook for differentials and clinical prioritisation

📌 Types
🔹 Benign: Pleomorphic adenoma, Warthin’s tumour
🔹 Malignant: Mucoepidermoid carcinoma, adenoid cystic carcinoma, carcinoma ex pleomorphic
🔹 Non-epithelial: Lymphoma, neurofibroma, sarcoma

📌 Risk Factors
• Radiation exposure
• Genetic syndromes (e.g. FAP)
• Family history

📌 Symptoms
• Painless mass (classic for benign)
• Facial nerve involvement (suggests malignancy)
• Pain, fixation, hard or irregular lump – all red flags
• Difficulty chewing, trismus, numbness, or overlying skin changes

📌 Red Flags for Malignancy
• Facial nerve palsy
• Pain or rapid growth
• Fixation to skin or deeper tissue
• Ill-defined or irregular surface
• Overlying skin changes or ulceration

📌 Differential Diagnoses
• Lymphadenopathy
• Sialadenitis (acute/chronic)
• Sialolithiasis
• Sjögren’s syndrome
• Viral infections (e.g. mumps)
• Sarcoidosis
• Salivary cysts
• Abscesses or tumours of minor salivary glands

📌 Investigations
• FNAC – first-line for diagnosis
• MRI/CT – to assess extent, facial nerve involvement, lymph nodes
• Ultrasound – for initial imaging
• Sialography & sialendoscopy – if stones suspected

📌 Management
• Benign: Superficial or total parotidectomy (nerve-sparing if possible)
• Malignant: Total parotidectomy ± facial nerve sacrifice
• Adjuvant radiotherapy ± neck dissection for advanced cancers
• Warthin’s: Conservative or surgical depending on symptoms
• Multidisciplinary team (MDT) involvement is essential

📌 Surgical Complications
Immediate:
• Facial nerve injury
• Tumour rupture
• Incomplete resection

Early (≤1 month):
• Temporary nerve palsy
• Auricular numbness
• Fistula
• Trismus
• Bite syndrome
• Wound infection, seroma, haematoma

Late:
• Frey’s syndrome (gustatory sweating)
• Crocodile tears (Bogorad syndrome)
• Persistent numbness
• Cosmetic defects
• Tumour recurrence

📌 Prognosis
• Benign: Good if fully excised
• Malignant: Prognosis depends on type, grade, and stage
• Early diagnosis improves outcomes significantly
• Ongoing long-term follow-up is critical

⚕️ FREE MSRA PODCAST – Obstructive Sleep Apnoea
🎧 A clear, high-yield breakdown of this common cause of snoring and daytime sleepiness – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Obstructive Sleep Apnoea (OSA) is a disorder marked by repeated episodes of upper airway obstruction during sleep, causing apnoeas (complete pauses) or hypopnoeas (partial obstruction), resulting in poor-quality, fragmented sleep.

📌 Causes & Risk Factors
• Obesity – especially fat around the neck
• Anatomical narrowing – large tonsils, small jaw, macroglossia
• Ageing – decreased pharyngeal muscle tone
• Male sex
• Alcohol, sedatives, smoking
• Hypothyroidism, acromegaly, nasal congestion
• Family history of OSA or snoring
🧠 Mnemonic: “OLD MAN’S SNORES” – Obesity, Large tonsils, Drugs (sedatives/alcohol), Male, Age, Nasal issues, Structural abnormalities, Neurological conditions, Oedema (macroglossia), Risk factors (genetics), Endocrine (hypothyroid), Smoking

📌 Pathophysiology
• During sleep, pharyngeal muscles relax
• In predisposed individuals, the airway collapses or narrows
• This causes airflow reduction or cessation, leading to:
– ↓ O₂ saturation
– ↑ CO₂
– Micro-arousals to restore breathing
• Sleep becomes fragmented, reducing time in REM and deep NREM sleep

📌 Symptoms
• Loud snoring, witnessed apnoeas
• Excessive daytime sleepiness, fatigue
• Morning headaches, dry mouth
• Concentration issues, irritability
• Nocturia, restless sleep, sexual dysfunction
🧠 Mnemonic: “STOP BANG” – Snoring, Tiredness, Observed apnoeas, Pressure (BP ↑), BMI ↑, Age, Neck size ↑, Gender (male)

📌 Differential Diagnosis
• Central sleep apnoea
• Primary snoring
• Depression, hypothyroidism, narcolepsy
• Shift work, poor sleep hygiene
• Medication effects (e.g. alcohol, sedatives, SSRIs)

📌 Diagnosis
• Polysomnography (PSG) – gold standard sleep study
• Apnoea-Hypopnoea Index (AHI):
– Mild: 5–14
– Moderate: 15–29
– Severe: ≥30
• HSAT (Home Sleep Apnoea Testing) in selected cases
• STOP-BANG for screening (pre-op or clinical suspicion)
• Also check TSH, HbA1c, BP, ENT anatomy

📌 Management
• Lifestyle: Weight loss, side sleeping, avoid alcohol/sedatives
• CPAP: Gold standard treatment – splints airway open with air pressure
• BiPAP: For severe/complex cases
• Mandibular advancement devices: For mild/moderate OSA or CPAP intolerance
• ENT referral: Consider surgery (tonsillectomy, UPPP) if structural cause
• Treat nasal congestion/allergies
• Modafinil only for persistent sleepiness despite CPAP – not first-line
❗ NICE recommends tailored treatment and home polygraphy first when possible

📌 Complications
• Hypertension, heart failure, arrhythmias, stroke
• Cognitive decline, memory issues, depression
• Increased driving and work accidents
• Insulin resistance, type 2 diabetes

📌 Prognosis
• Excellent with adherence to CPAP and lifestyle changes
• Effective treatment improves sleep quality, cardiometabolic health, and reduces mortality
• Poorly managed OSA leads to major cardiovascular and cognitive risks

⚕️ FREE MSRA PODCAST – Otosclerosis
🎧 A clear, high-yield breakdown of this progressive ear bone disorder causing hearing loss – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Otosclerosis is a progressive condition involving abnormal bone growth in the middle ear, typically around the stapes bone. This leads to conductive hearing loss, and in advanced cases, mixed hearing loss if the inner ear is affected.

📌 Causes & Risk Factors
• Genetic predisposition (autosomal dominant)
• Hormonal influences, especially during pregnancy
• Possible link to measles virus
• Environmental factors, e.g., non-fluoridated water (less conclusive)
🧠 Mnemonic: “FARM” – Family history, Age (15–45), Race (White/Asian), Female sex

📌 Pathophysiology
• Abnormal bone remodelling leads to stapes fixation
• Fixed stapes can't vibrate → blocked sound transmission
• May affect the otic capsule and cochlea → sensorineural involvement
🦴 Mechanical issue that disrupts normal sound conduction

📌 Symptoms
• Progressive hearing loss, especially of low frequencies
• Tinnitus
• Sensation of fullness or blocked ear
• Dizziness (less common)
🧠 Mnemonic: “HATS” – Hearing loss, Autophony, Tinnitus, Sensation of blockage

📌 Differential Diagnosis
• Chronic otitis media
• Congenital stapes fixation (non-progressive)
• Meniere’s disease (if vertigo dominates)
• Tympanosclerosis, Paget’s disease, Osteogenesis imperfecta

📌 Diagnosis
• Pure-tone audiometry – shows conductive or mixed loss
• Carhart’s notch at 2 kHz – classic finding
• Tympanometry – may show reduced compliance
• CT scan – visualises halo sign at oval window, rules out other causes

📌 Management
• Hearing aids – initial management for milder cases
• Surgical options:

• Stapedectomy – removes and replaces stapes

• Stapedotomy – fenestration with prosthesis
  • Medical options: Sodium fluoride or bisphosphonates (limited evidence)
  🧠 Surgery offers up to 95% improvement in conductive loss

📌 Complications
• Surgical:

• Sensorineural hearing loss (1–2%)

• Facial nerve injury, eardrum perforation, taste disturbance, tinnitus
  🧠 Mnemonic: “FLAPT” – Facial nerve, Loss of hearing, Accidental taste disturbance, Perforation, Tinnitus

📌 Prognosis
• Excellent with surgery – long-term hearing improvement
• Hearing may decline with age but not due to surgery itself
• Untreated cases may result in significant loss, but rarely complete deafness

• Soft foods, swallowing therapy
• Treat GERD with PPIs
💉 Surgical (symptomatic):
• Dolman’s endoscopic stapling (small pouches)
• Open diverticulectomy + cricopharyngeal myotomy (larger pouches)
🎯 Aim = relieve pressure & prevent recurrence
💡 Endoscopic = faster recovery, less invasive
💡 Open = slightly lower recurrence risk

📌 Complications
• Aspiration pneumonia
• Malnutrition, weight loss
• Esophageal stricture
• Perforation or bleeding (post-surgery)
• Rare: Squamous cell carcinoma within pouch

📌 Prognosis
• 👍 Good with appropriate treatment
• Regular follow-up essential
• Choice of surgery depends on patient fitness + pouch size

🎧 FREE MSRA PODCAST – Otitis Externa (Swimmer’s Ear) Explained

Essential, rapid revision of Otitis Externa for the MSRA: causes, clinical clues, red flags, and management—all straight from UK NICE-guided notes and exam themes. Boost your ENT knowledge, whether you’re prepping for exams or patient care!

🧠 Key Learning Points

Definition
• Otitis externa is inflammation or infection of the external ear canal (often called “swimmer’s ear”).
• Usually bacterial (Pseudomonas, Staph aureus), less commonly fungal (Candida, Aspergillus).
• Can be acute (<3 weeks), chronic (>3 months), or necrotising (rare, severe).

Natural Defences
• Ear canal self-cleans by epithelial migration.
• Earwax (cerumen) contains lysozyme & other antimicrobial agents.
• Defence breakdown (moisture, trauma, eczema) = ↑ infection risk.

Causes
• Infectious: bacteria (Pseudomonas, Staph aureus), fungi (Candida, Aspergillus).
• Non-infectious: moisture (swimming), cotton buds, irritants (hairspray, eardrops), dermatological issues (eczema, psoriasis).

Risk Factors
• Swimming, especially in children (7–12 years).
• Diabetes, immunosuppression.
• Hearing aids, earphones, narrow canals, wax imbalance, prior otitis externa, grommets, ear trauma, radiotherapy.
• Skin disease (eczema, psoriasis).

Pathophysiology
• Breakdown in skin barrier → infection/inflammation in canal.
• Results in: pain, swelling, redness, discharge, hearing loss.

Differential Diagnosis
• Otitis media, cholesteatoma, chronic suppurative otitis media, foreign body, impacted wax, malignancy, referred pain (teeth, jaw, sinuses), barotrauma, eczema.

Epidemiology (UK)
• ~10% lifetime risk.
• Peak: ages 7–12.
• More frequent in females.
• 1–3% of GP visits; only ~3% need ENT referral.
• Peaks in late summer (swimming!).

Clinical Features
• Otalgia, itching, discharge, fullness, hearing loss, pain on tragus or pinna movement.
• Exam: red, swollen canal, scaly skin, ± cellulitis, lymphadenopathy.

Types
• Acute diffuse OE – most common, bacterial, widespread swelling.
• Chronic OE – often fungal/inflammatory.
• Furuncle – boil, localised, very painful.
• Contact dermatitis – allergic/irritant.
• Necrotising OE – invasive, life-threatening, especially in diabetics/immunosuppressed (severe pain, facial nerve palsy = red flag, urgent ENT referral).

Investigations
• Clinical diagnosis usually sufficient.
• Ear swabs only if recurrent, severe, or non-resolving.
• Signs of perforation: taste of drops, air escapes from ear on Valsalva, known grommets.
• Imaging (CT/MRI) if necrotising OE suspected.

Management
• Topical: Antibiotic + steroid drops (ciprofloxacin + dexamethasone), acetic acid for mild/preventive.
• Aural toilet: Debris removal (avoid syringing if perforated, use microsuction).
• Oral antibiotics: Only for severe cellulitis/systemic illness—use flucloxacillin or erythromycin.
• ENT advice: If severe or not responding.
• Ear wicks may be needed for drops in swollen canal.
• Self-care: Keep ear dry, avoid trauma, use swimmer’s drops before/after swimming, olive oil for wax, manage eczema.
• Prevention: No cotton buds, careful with earphones.

Complications
• Cellulitis, abscess, temporary hearing loss.
• Chronic OE, necrotising OE (skull base osteomyelitis), sepsis (rare).
• Red flags: severe pain, facial palsy, diabetes/immunosuppressed, refer urgently.
