Otitis Media in Children Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Otitis Media in Children. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Otitis Media in Children Indian Medical PG Question 1: All are intracranial complications of otitis media except which of the following?
- A. Brain abscess
- B. Hydrocephalus
- C. Lateral sinus thrombophlebitis
- D. Facial nerve palsy (Correct Answer)
Otitis Media in Children Explanation: ***Facial nerve palsy***
- This is an **extracranial complication** of otitis media affecting the **facial nerve within the temporal bone**, not an intracranial structure.
- The facial nerve (CN VII) runs through the **fallopian canal** in the temporal bone and can be affected by inflammation from adjacent mastoid or middle ear infection.
- Classified as a **temporal bone complication** rather than an intracranial complication.
*Lateral sinus thrombophlebitis*
- This is a true **intracranial complication** involving thrombosis of the **sigmoid and lateral venous sinuses** within the cranial cavity.
- Results from direct extension of infection through the **mastoid tegmen** or via septic thrombophlebitis.
- Presents with features of sepsis, headache, and papilledema.
*Brain abscess*
- A severe **intracranial complication** representing focal suppurative infection within the **brain parenchyma** (commonly temporal lobe or cerebellum).
- Occurs through direct extension via bony erosion, retrograde thrombophlebitis, or hematogenous spread.
- Requires urgent neurosurgical intervention.
*Hydrocephalus*
- An **intracranial complication** that can occur secondary to **otogenic meningitis** or **lateral sinus thrombosis**.
- Results from impaired CSF absorption or obstruction of CSF pathways.
- More common in pediatric otitis media with CNS complications.
Otitis Media in Children Indian Medical PG Question 2: What are the X-ray findings associated with chronic otitis media?
- A. Honeycombing of mastoid
- B. Sclerosis with cavity in mastoid (Correct Answer)
- C. Clear-cut distinct bony partition between cells
- D. Increased pneumatization of mastoid cells
Otitis Media in Children Explanation: ***Sclerosis with cavity in mastoid***
- Chronic otitis media leads to **long-standing inflammation** and **destruction** of the mastoid air cells, resulting in dense, **sclerotic bone** with cavity formation due to bone erosion.
- This is the **characteristic X-ray finding** in chronic otitis media, indicating osseous remodeling and bone destruction from persistent infection.
- The sclerosis represents reactive bone formation, while cavities form from **coalescence** of destroyed air cells.
*Honeycombing of mastoid*
- Honeycombing describes a **normal, well-pneumatized mastoid** with numerous small, distinct air cells visible on X-ray.
- This appearance indicates a healthy mastoid bone with good aeration and is **inconsistent** with chronic inflammation.
- Chronic otitis media causes bone remodeling and sclerosis, **not** preserved pneumatization.
*Clear-cut distinct bony partition between cells*
- This describes **normal mastoid anatomy** where air cells are well-defined and separated by thin, intact bony septa.
- In chronic otitis media, these septa are typically **eroded or thickened** by inflammation, leading to loss of distinctness.
- The inflammatory process causes destruction and sclerosis, **not** preservation of normal architecture.
*Increased pneumatization of mastoid cells*
- Increased pneumatization indicates **excessive air cell development**, which is opposite to the changes seen in chronic infection.
- Chronic otitis media causes **destruction and sclerosis** of air cells, not increased pneumatization.
- This would be seen in normal developmental variants, not chronic inflammatory disease.
Otitis Media in Children Indian Medical PG Question 3: While discharging a patient of meningitis due to Haemophilus influenzae, what is the essential step you would take?
- A. Assess the patient's developmental milestones
- B. Refer the patient for physical rehabilitation
- C. Perform an EEG to assess brain activity
- D. Test for hearing loss using auditory response testing (Correct Answer)
Otitis Media in Children Explanation: ***Test for hearing loss using auditory response testing***
- **Hearing loss** is a common and serious complication of *Haemophilus influenzae* meningitis, potentially affecting up to 30% of survivors, and early detection is crucial for intervention [1].
- **Auditory brainstem response (ABR) testing** is a reliable method to assess hearing function in patients, especially children, after meningitis.
*Perform an EEG to assess brain activity*
- While meningitis can cause neurological complications like seizures, an **EEG** is primarily indicated for assessing **seizure activity** or other significant alterations in brain electrical function, not as a routine discharge step for all *Haemophilus influenzae* meningitis patients [2].
- An EEG would be performed if there were **clinical signs of seizures** or other neurological deficits requiring immediate investigation during hospitalization, rather than as a discharge routine.
*Assess the patient's developmental milestones*
- Assessing **developmental milestones** is important for all children, especially after a severe illness like meningitis, but it is a **long-term follow-up** concern and not an essential **immediate discharge step** focused on a specific, common complication.
- Developmental assessments are typically part of routine pediatric check-ups and ongoing neurodevelopmental surveillance, rather than a single acute discharge intervention.
*Refer the patient for physical rehabilitation*
- **Physical rehabilitation** is necessary if the patient has experienced **motor deficits** or other physical impairments due to meningitis-related complications, such as stroke or cerebral palsy.
- However, it is not an essential universal discharge step for all meningitis patients; it is only indicated if specific rehabilitation needs have been identified.
Otitis Media in Children Indian Medical PG Question 4: Which of the following statements about tubercular otitis media is false?
- A. Spreads through the eustachian tube
- B. Usually affects only one ear
- C. Causes painful ear discharge (Correct Answer)
- D. May cause multiple perforations
Otitis Media in Children Explanation: ***Causes painful ear discharge***
- **Pain** is typically an **absent or minimal symptom** in tubercular otitis media, even with significant ear discharge.
- The discharge is usually **thin, watery, and non-purulent**, reflecting the indolent nature of the infection.
*Spreads through the eustachian tube*
- Tubercular otitis media can spread via the **eustachian tube** from the nasopharynx, especially in cases of active pulmonary or pharyngeal tuberculosis.
- This is a common route for infectious agents to reach the middle ear.
*Usually affects only one ear*
- Tubercular otitis media predominantly presents as a **unilateral infection**.
- While bilateral involvement can occur, it is less common than unilateral presentation.
*May cause multiple perforations*
- Tubercular otitis media is notorious for causing **multiple, small perforations** in the tympanic membrane.
- This feature, often described as a "sieve-like" drum, is a characteristic diagnostic clue for the condition.
Otitis Media in Children Indian Medical PG Question 5: A 35-year-old patient presents with hearing loss and discomfort in the right ear. Examination reveals keratin accumulation in the ear canal. What is the most likely diagnosis?
- A. Keratosis obturans (Correct Answer)
- B. Exostosis
- C. Cerumen
- D. Otitis externa
Otitis Media in Children Explanation: ***Keratosis obturans***
- This condition is characterized by an **accumulation of desquamated keratin** and epithelial debris in the bony external auditory canal, leading to earache, conductive hearing loss, and sometimes widening of the ear canal.
- The patient's presentation of **hearing loss**, **discomfort in the right ear**, and **keratin accumulation** aligns directly with the description of keratosis obturans.
*Exostosis*
- Exostoses are **bony growths** in the ear canal, often associated with cold water exposure.
- While they can cause hearing loss and earwax impaction, they do not involve primary **keratin accumulation** as described.
*Cerumen*
- **Cerumen** is normal earwax, which is a mix of secretions and desquamated cells.
- While excessive cerumen can cause hearing loss, the description of **keratin accumulation** suggests a more organized, dense plug than typical cerumen impaction.
*Otitis externa*
- **Otitis externa** is an inflammation or infection of the ear canal, presenting with pain, redness, swelling, and discharge.
- While it can cause discomfort and sometimes lead to debris, the primary finding is **inflammation**, not specifically a large accumulation of keratin.
Otitis Media in Children Indian Medical PG Question 6: A child presents with recurrent ear infections and conductive hearing loss. What is the most likely diagnosis?
- A. Glue ear (Correct Answer)
- B. Acute otitis media
- C. Otitis externa
- D. Chronic otitis media
Otitis Media in Children Explanation: ***Correct: Glue ear***
- **Glue ear** (otitis media with effusion - OME) is the **most common cause of conductive hearing loss in children**
- Frequently develops after **recurrent episodes of acute otitis media**, with persistent middle ear effusion
- The thick, glue-like fluid behind the tympanic membrane impairs ossicular movement, causing **conductive hearing loss**
- Classic presentation: child with history of recurrent ear infections who develops persistent hearing impairment between acute episodes
- Diagnosis confirmed by **tympanometry** showing flat type B curve and **otoscopy** revealing retracted tympanic membrane with fluid level or air bubbles
*Incorrect: Chronic otitis media*
- Implies **persistent tympanic membrane perforation** with chronic discharge (>6-12 weeks)
- More severe, established pathology with potential complications like cholesteatoma
- While it causes conductive hearing loss, it's **less common** than OME in typical pediatric presentations
- Would expect to see persistent otorrhea and visible perforation on examination
*Incorrect: Acute otitis media*
- Characterized by **sudden onset** with acute symptoms: otalgia, fever, irritability, bulging red tympanic membrane
- While recurrent episodes are common in children, the question describes ongoing conductive hearing loss, suggesting **persistent effusion** rather than isolated acute episodes
- Each acute episode resolves, but may be followed by OME
*Incorrect: Otitis externa*
- **External ear canal** infection ("swimmer's ear"), not a middle ear problem
- Presents with ear pain worsened by **tragal pressure** or pinna manipulation, canal edema, and discharge
- Does **not cause conductive hearing loss** unless severe canal occlusion occurs
- Not associated with recurrent middle ear infections
Otitis Media in Children Indian Medical PG Question 7: Prior history of ear surgery and scanty, foul-smelling, painless discharge from the ear are characteristic features of which of the following lesions?
- A. ASOM
- B. Cholesteatoma (Correct Answer)
- C. Central perforation
- D. Otitis externa
Otitis Media in Children Explanation: ***Cholesteatoma***
- The **combination of all three features** (prior ear surgery + scanty, foul-smelling, painless discharge) is highly characteristic of cholesteatoma.
- A prior history of ear surgery, particularly for **chronic otitis media**, can predispose to or be related to an **acquired cholesteatoma**.
- **Scanty, foul-smelling, painless discharge** (otorrhea) is a hallmark symptom of cholesteatoma, with the **foul smell** being particularly distinctive due to breakdown of keratin debris and secondary infection.
- The **painless** nature helps differentiate it from acute infections.
*ASOM (Acute Suppurative Otitis Media)*
- ASOM typically presents with **acute otalgia** (ear pain) and a **profuse purulent, non-foul-smelling discharge** following tympanic membrane perforation.
- It is an acute infection and usually does not have a prior history of ear surgery as a direct cause of the current discharge.
- The presence of **pain** and absence of foul smell distinguish it from cholesteatoma.
*Central perforation*
- A central perforation of the tympanic membrane often results in **intermittent, mucoid discharge** during upper respiratory tract infections, which is usually not foul-smelling.
- While it can be associated with discharge, the characteristic **foul smell** and **prior surgery history** point away from simple central perforation as the primary diagnosis.
- The discharge is typically more profuse during active infection.
*Otitis externa*
- **Otitis externa** primarily affects the ear canal, causing **pain, tenderness, and sometimes a watery or purulent discharge**, but it does not typically present with a foul-smelling discharge associated with a prior ear surgery history.
- It is usually due to infection of the external auditory canal skin and not related to middle ear pathology or prior surgery in the way a cholesteatoma is.
- The **painful** nature is a key distinguishing feature.
Otitis Media in Children Indian Medical PG Question 8: The treatment of choice for atticoantral variety of chronic suppurative otitis media is:
- A. Mastoidectomy (Correct Answer)
- B. Medical management
- C. Underlay myringoplasty
- D. Insertion of ventilation tube
Otitis Media in Children Explanation: **Correct: Mastoidectomy**
- The **atticoantral** variety of chronic suppurative otitis media (CSOM) is typically associated with **cholesteatoma**, which necessitates surgical eradication to prevent complications such as intracranial infection, facial nerve palsy, and labyrinthine destruction.
- **Mastoidectomy** is the treatment of choice to remove the cholesteatoma and achieve a safe, dry ear by clearing disease from the mastoid air cells and attic.
*Incorrect: Medical management*
- This approach is typically used for the **tubotympanic** (mucosal/safe) type of CSOM, which involves a central perforation without cholesteatoma.
- It is **ineffective in the presence of cholesteatoma**, as antibiotics cannot penetrate the keratinized debris matrix and do not eradicate the underlying pathology.
*Incorrect: Underlay myringoplasty*
- This procedure repairs a **tympanic membrane perforation** but does not address the underlying cholesteatoma or disease within the mastoid and attic.
- It is used for **safe, dry perforations**, usually associated with the tubotympanic type of CSOM after the ear has been rendered inactive.
*Incorrect: Insertion of ventilation tube*
- Ventilation tubes (grommets) are primarily used for **recurrent acute otitis media** or **otitis media with effusion (glue ear)** to equalize middle ear pressure and facilitate drainage.
- They are **not indicated for CSOM**, especially the atticoantral type with cholesteatoma, as they do not resolve the chronic infection or remove the pathological tissue.
Otitis Media in Children Indian Medical PG Question 9: A 6-year-old child presented with history of recurrent upper respiratory tract infections, mouth breathing, nasal obstruction and hearing impairment. Management will be:
- A. Tonsillectomy
- B. Adenoidectomy with grommet insertion (Correct Answer)
- C. Myringotomy with grommet
- D. Myringotomy
Otitis Media in Children Explanation: ***Adenoidectomy with grommet insertion***
- This child presents with classic features of **adenoid hypertrophy** causing eustachian tube dysfunction: recurrent upper respiratory tract infections, mouth breathing, nasal obstruction, and hearing impairment
- The hearing impairment indicates **otitis media with effusion (OME/glue ear)** secondary to eustachian tube obstruction by the enlarged adenoids
- **Adenoidectomy** addresses the underlying cause by removing the obstructing adenoid tissue, relieving nasal obstruction and restoring eustachian tube function
- **Grommet insertion (tympanostomy tube)** addresses the OME, providing immediate improvement in hearing while the eustachian tube function recovers post-adenoidectomy
- This combined approach treats both the **cause** (adenoid hypertrophy) and **effect** (middle ear effusion)
*Tonsillectomy*
- Tonsillectomy is indicated for recurrent **bacterial tonsillitis** (typically streptococcal) or severe tonsillar hypertrophy causing obstructive sleep apnea
- While tonsillar hypertrophy can contribute to upper airway obstruction, the primary issues here are **nasal obstruction** and **hearing impairment**, which are caused by adenoid hypertrophy, not tonsillar disease
- This procedure would not address the eustachian tube dysfunction or the middle ear effusion
*Myringotomy with grommet*
- This addresses the **OME and hearing impairment** but fails to treat the underlying cause of the problem (adenoid hypertrophy)
- Without removing the enlarged adenoids, the **eustachian tube obstruction persists**, leading to recurrent middle ear effusions even after grommet insertion
- The nasal obstruction, mouth breathing, and recurrent URTIs would continue unaddressed
*Myringotomy*
- Myringotomy alone creates a temporary incision in the tympanic membrane to drain middle ear fluid but does not include grommet insertion
- The incision heals rapidly (within days), and **effusion typically recurs** without a grommet to maintain ventilation
- This provides only temporary relief and does not address either the underlying adenoid pathology or provide sustained middle ear ventilation
Otitis Media in Children Indian Medical PG Question 10: Which of the following is the MOST common complication of chronic otitis media?
- A. Hearing loss (Correct Answer)
- B. Epistaxis
- C. Facial nerve paralysis
- D. Mastoiditis
Otitis Media in Children Explanation: ***Hearing loss***
- **Chronic otitis media** is the **MOST common complication**, affecting virtually all patients to some degree.
- Damage to the **ossicles**, tympanic membrane perforation, and middle ear effusion lead primarily to **conductive hearing loss**.
- Long-standing disease can also cause **sensorineural hearing loss** through toxin diffusion to the inner ear or erosion of the otic capsule.
- This is the hallmark and nearly universal consequence of chronic otitis media.
*Epistaxis*
- **Epistaxis (nosebleeds)** originates from the nasal passages and has no direct relationship to middle ear pathology.
- Not a complication of **chronic otitis media**.
*Facial nerve paralysis*
- While a recognized complication, **facial nerve paralysis** is relatively uncommon and typically occurs with **cholesteatoma** eroding the facial nerve canal or in severe suppurative disease.
- Represents an advanced complication rather than the most frequent outcome.
*Mastoiditis*
- **Mastoiditis** is indeed a complication of chronic otitis media, occurring when infection spreads to the **mastoid air cells**.
- Presents with postauricular tenderness, swelling, and fever.
- However, with modern antibiotic therapy, it is **less common** than hearing loss, which occurs in nearly all cases of chronic otitis media.
