ENT Flashcards
Which of the following are NOT aetiological factors in laryngeal or pharyngeal cancer?
Question 1Select one:
A.
Human papilloma virus
B.
Cigarette smoking
C.
Drinking alcohol
D.
Working with hardwoods
Hardwood dust exposure is not a recognised factor in the development of cancer of the larynx. It has been associate with cancer i the paranasal sinuses but not elsewhere in the upper aerodigestive tract.
At this age recurrent acute otitis media is common. Six episodes a year may be seen in children with normal immunity and does not require further investigation unless other symptoms such as hearing loss are also found.
Which of the following symptoms is often the sole presenting complaint in cancers of the head and neck?
Please select all that apply.
Select one or more:
A.
Shortness of breath
B.
Haemoptysis
C.
Hoarseness
D.
Sensation of a lump in the throat (globus)
E.
Dysphagia
Hoarseness is often the reason patients present with cancers of the head and neck. This may either be due to tumours of the vocal cord itself or tumours of the hypopharynx causing immobility of the vocal cord.
Certain symptoms have been defined as ‘red flags’ which should result in patients being referred urgently and being given an ENT appointment within 2 weeks. Which of the situations below are NOT mentioned in the guidelines for urgent referral?
Globus sensation alone is not recommended for urgent referral. If patients have associated hoarseness or dysphagia, or if there is other cause for suspicion, then referral should be urgent

Via what route does the normal middle ear receive the air within it?
Question 6Select one:
A.
Via the sinuses
B.
Via the Eustachian tube
C.
Via the mastoids
D.
Via the tympanic membrane
The normal middle ear absorbs a certain amount of the gas within it continuously. This needs to be replaced. A small volume of air passes up the Eustachian tube when it opens with swallowing, maintaining atmospheric pressure within the middle ear cleft.
There is evidence that certain additional treatments can improve the resolution of the underlying otitis media with effusion. Sometimes these are offered at the same time as grommet insertion.
Select the one correct treatment from the list below
Question 13Select one:
A.
Antibiotics
B.
Tonsilectomy
C.
Adenoidectomy
D.
Cranial Osteopathy
Adenoidectomy
While antbiotics may help in the treatment of the recurrent acute otitis media asociated with otitis media with effusion there is no evidence that they influence the rate of resolution of the effusion or the Eustachian tube function
Which of the following is thought to be the underlying pathophysiology behind otitis media with effusion?
Question 14Select one:
A.
Allergy to dairy products
B.
Upper respiratory tract infection
C.
Poor Eustachian tube function
D.
Tonsillitis
Poor Eustachian tube function
While an upper respiratory tract infection may cause middle ear effusion this will normally resolve within a few weeks at most. When the effusion is persistent for 3 months there must be some other cause.
Which of the following treatments would be an appropriate choice for management of otitis media with effusion, characterised principally by moderate conductive hearing loss?
Question 17Select one:
A.
Hearing aid provision
B.
Long term low dose antibiotics
C.
Avoidance of certain foods
D.
Nasal steroid sprays
Hearing aid provision
Antibiotics have not been shown to alter the course of otitis media with effusion.
how do grommets prevent accumulation of a middle ear effusion?
Question 20Select one:
A.
By improving Eustachian tube function
B.
By allowing equalisation of pressure between the air in the middle ear and the atmosphere
C.
By allowing the middle ear effusion to drain via the grommet
D.
By allowing the effusion to pass down the Eustachian tube
By allowing equalisation of pressure between the air in the middle ear and the atmosphere
No. Insertion of a grommet has no effect on eustachian tube function. The grommet prevents the hearing loss and recurrent infection while it is in situ. During this time Eustachian tube function will improve in the majority, so it is no longer required once it has spontaneously extruded.
A mother brings her six-month-old baby to your GP surgery first thing one morning because the baby has been awake since 2 a.m. screaming with pain and refusing to sleep. He has had a cold for 2 days and seemed to have a raised temperature last night. The baby had finally fallen asleep at 7 a.m., exhausted, and when his mum picked him up to come to the surgery, she noticed some green discharge on the pillow that appeared to have come from his right ear. You examine the baby and see that his right ear canal is full of pus and that it is difficult to visualise the right tympanic membrane.

Gram positive vs Gram negative
You see here the G+ in violet or blue (as it retains both the cristal violet and safranin) while Gram negative bacteria when washed with alcohol loose the Crystal violet and retain the safranin (pink) - Suspect acute otitis media in children with ear pain (ear symptoms can be subtle especially in young pre-verbal children), with or without fever
The presence of middle ear effusion on otoscopy is a prerequisite for diagnosis of acute otitis media
Confirming diagnosis by pneumatic otoscopy can reduce overdiagnosis and unnecessary antibiotic prescribing. - phenoxymethylpenicillin
Consider oral antibiotics in systemically unwell children, those at high risk of complications because of pre-existing comorbidity, children under 2 with bilateral acute otitis media and in children of any age with acute otitis media and acute ear discharge caused by a spontaneous rupture of the eardrum

, and olfactory receptors are replaced every Blank 3
. Both taste and smell receptors are replaced by
. The olfactory bulb neurons pass along the Blank 5
to reach the Blank 6
and olfactory areas.
- Taste and smell receptors are called chemoreceptors → ✅ Correct. Chemoreceptors detect chemical stimuli, which is the basis of taste and smell.
- Taste receptor cells are replaced every 10 days → ✅ Correct. Taste buds regenerate frequently due to the harsh environment of the oral cavity.
Olfactory receptors are replaced every 2 months → ✅ Correct. Olfactory receptor neurons have a longer lifespan but still regenerate.
Both taste and smell receptors are replaced by basal cells → ✅ Correct. Basal cells serve as stem cells that generate new sensory receptor cells.
The olfactory tract leads to the olfactory cortex,
- The olfactory tract leads to the olfactory cortex, primarily in the temporal lobe.
The vagus nerve passes out of the cranial cavity via the Blank 1 Question 7
foramen. The first (most superior) nerve to branch off of the vagus nerve is the Blank 2 Question 7
. The vagus nerve descends through the neck within the Blank 3 Question 7
. The Blank 4 Question 7
nerve branches off the vagus in the mediastinum and ascends.
The vagus nerve passes out of the cranial cavity via the jugular foramen → ✅ Correct. The vagus nerve exits the skull through the jugular foramen, along with the glossopharyngeal (CN IX) and accessory (CN XI) nerves.
The first (most superior) nerve to branch off of the vagus nerve is the superior laryngeal nerve → ✅ Correct. The superior laryngeal nerve is an early branch of the vagus and divides into internal (sensory) and external (motor) branches to innervate structures of the pharynx and larynx.
The vagus nerve descends through the neck within the carotid sheath → ✅ Correct. The carotid sheath contains the vagus nerve (CN X), common carotid artery, and internal jugular vein as they descend through the neck.
The recurrent laryngeal nerve branches off the vagus in the mediastinum and ascends. → ✅ Correct. The recurrent laryngeal nerve branches at different levels:
Right side: Loops around the subclavian artery
Left side: Loops around the aortic arch
It then ascends back toward the larynx, providing motor innervation to most of the intrinsic laryngeal muscles.

Answer 4 Question 9
Choose…
Otitis media with effusion will NOT have the symptoms and signs of acute inflammation. True or False?
✅ Correct answer:Adenoidectomy is a surgical procedure involving the removal of the adenoids, which are lymphoid tissues located in the nasopharynx (behind the nose and above the soft palate). It is often considered in children with recurrent or chronic ear (OME) , nose, and throat (ENT) issues. Enlarged adenoids can obstruct the Eustachian tube, impairing middle ear ventilation and contributing to fluid buildup.
✅Glandular fever (infectious mononucleosis, caused by Epstein-Barr virus) leads to atypical lymphocytes on a blood smear.
These are large, irregularly shaped lymphocytes responding to viral infection.
✅ **Correct answer: Steroids (e.g., Dexamethasone)
In severe tonsillitis, steroids (like dexamethasone) help reduce swelling and pain.
IV fluids, analgesia, and airway management may also be needed.
✅ Correct answer: Grommet (ventilation tube) insertion
Antibiotics are NOT routinely given for OME unless there is superimposed bacterial infection.
If OME persists for >3 months with hearing loss, the second-line treatment is grommet insertion.
Otitis media with effusion will NOT have the symptoms and signs of acute inflammation. True or False?
✅ Correct answer: True
OME does NOT cause fever, ear pain, or redness of the tympanic membrane.
Instead, it leads to painless hearing loss and a dull tympanic membrane due to fluid buildup.

✅ Correct answer: Hodgkin’s Disease (Lymphoma)
Alcohol-induced lymph node pain is a rare but characteristic feature of Hodgkin’s lymphoma.
This pain is thought to be caused by vascular expansion within the lymph node when alcohol is consumed.
✅ Correct answer: Pharyngeal pouch
Pharyngeal pouches (Zenker’s diverticulum) occur mostly in older men due to weakness in the pharyngeal wall.
Symptoms include dysphagia (difficulty swallowing), regurgitation of food, and gurgling sounds in the neck.
✅ Correct answer: Thyroglossal cyst
Thyroglossal cysts are midline neck lumps found between the thyroid isthmus and hyoid bone.
They move upwards on swallowing and protrusion of the tongue.
Branchial cysts are found laterally (NOT in the midline).
✅ Correct answer: Cystic hygroma
Cystic hygromas are congenital lymphatic malformations that appear in the neck or axilla within the first 2 years of life.

✅ Correct answer: Centor criteria
Centor criteria help determine the likelihood of Group A Streptococcus (GAS) pharyngitis.
Factors include:
Fever >38°C
Absence of cough
Tender anterior cervical lymphadenopathy
Tonsillar exudates
A score of 3 or 4 increases the likelihood of a bacterial infection and may warrant antibiotics.
✅ Correct answer: Streptococcus pyogenes (Group A strep)
Streptococcus pyogenes (GAS) is responsible for bacterial tonsillitis and pharyngitis.
It can lead to complications like rheumatic fever and post-streptococcal glomerulonephritis.
✅ Correct answer: Viruses
Most tonsillitis cases (~70-90%) are viral, caused by:
Adenovirus
Rhinovirus
Influenza
Epstein-Barr virus (EBV) (causing infectious mononucleosis/glandular fever)
✅ Correct answer: False
Throat swabs are not routinely done because most cases are viral and self-limiting.

in the middle ear the stapes footplate sint on what part of the inner ear
Cochlear (oval window )
the facial nerve travels through the internal acoustic meatus which bone of the skull is this located ?
**Temporla bone
**The facial nerve (cranial nerve VII) enters the internal acoustic meatus along with the vestibulocochlear nerve (cranial nerve VIII).
This opening is found in the petrous portion of the temporal bone, which is the hardest part of the skull.
After entering the internal acoustic meatus, the facial nerve travels through the facial canal, then exits the skull via the stylomastoid foramen.
On flexible laryngoscopy, she is noted to have a left vocal cord that fails to elongate during phonation.
Which nerve has most likely been damaged?
- Damage to the external laryngeal nerve results in a vocal cord that cannot be tensed due to loss of cricothyroid function. This results in an inability to produce notes of high frequency.
- The thyroid gland has two nerves as close relations: the external laryngeal and recurrent laryngeal nerves.
- The recurrent laryngeal nerve is intimately related to the inferior poles of the thyroid, including the inferior thyroid artery. It innervates all the intrinsic muscles of the thyroid, except the cricothyroid muscle which is innervated by the external branch of the superior laryngeal nerve.
- The cricothyroid is the only muscle that elongates the vocal cords.
- Therefore, damage to the external laryngeal nerve results in a vocal cord that cannot be tensed due to loss of cricothyroid function. This results in an inability to produce notes of high frequency.
