Which of the following is the MOST common complication of chronic otitis media?
Otitis Media in Children Indian Medical PG Practice Questions and MCQs
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)
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.
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
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.
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)
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.
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
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.
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
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.
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
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
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
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.
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
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.
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
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
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
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.
