Questions Samples :
A patient underwent dental procedure 2 days ago and then he develop numbness on upper lip. Which of the following nerve is most likely affected?
- Facial nerve
- Inferior alveolar nerve
- Infraorbital nerve
- Oculomotor nerve
The trigeminal nerve has three branches i.e. ophthalmic, maxillary and
mandibular. Maxillary branch is called infraorbital nerve as soon as it
enters the infraorbital canal. This nerve innervates (sensory) the lower
eyelid, upper lip and part of the nasal vestibule. The inferior alveolar
nerve is a branch of mandibular nerve and carries sensory supply from
lower teeth. It gives of another branch called mental nerve that carries
sensation from chin and lower lip.
A 23 year old boy has nasal bleeding for 10 minutes. There is no history
of trauma. On examination: there was posterior nasal oozing of blood. What
is best treatment?
- Anterior nasal packing
- Constrictive spray
- Posterior nasal packing
Management: Resuscitate the patient (if necessary) – remember the
ABCD(E) of resuscitation. Ask the patient to sit upright, leaning slightly
forward, and to squeeze the bottom part of the nose (NOT the bridge of
the nose) for 10-20 minutes to try to stop the bleeding. The patient
should breathe through the mouth and spit out any blood/saliva into a
bowl. An ice pack on the bridge of the nose may help 3. Nasal cautery
is a common treatment of epistaxis. A caustic agent such as silver
nitrate (chemical cautery) or an electrically charged wire such as
platinum. Bleeding that fails to respond to pressure may be managed
with epinephrine, or silver nitrate. Severe bleeding that is brisk or does
not respond to the previous measures may require packing or
emergency referral. The best initial approach in hospital setting is
nasal packing. If a comatosed patient suddenly have nosebleed, then it
is best to lay him in side ways so that blood comes out instead of going
inside his lungs.
60 year old male comes to you with unilateral parotid swelling for last 3 years. He says there is no pain in the area and swelling is constant. There is no relation of swelling with the eating. On examination, there is 4cm swelling in front of ear without any tenderness, erythema and normal facial nerve function. Which of the following is most likely diagnosis?
- Bacterial parotitis
- Parotid duct calculus
- Pleomorphic adenoma,
Benign pleomorphic adenoma present with painless swelling, gradually
increasing in size and not associated with any fever or tenderness. In
bacterial parotitis, there is fever along with the tenderness. Facial
nerve involvement would rise the suspicion toward malignancy. Parotid
duct calculus, if present, would result in increased swelling during
A newborn got the injury of stylomastoid foramen near the base of the skull. Which of the following clinical feature help in diagnosis?
- Loss of eye closure
- Loss of mastication function
- Loss of maxillary sensation
- Loss of sensation in mandibular region
Facial nerve leave the skull via stylomastoid process and is likely to be damaged in this patient. The orbicularis oculi muscle, supplied by facial is likely to be paralysed resulting in failure of closure of the eye. It is usually associated with facial palsy, shifting of face to the opposite side. Nasolacrimal secretion will also be decreased because it is also supplied by facial nerve. Loss of maxillary sensation is due to maxillary branch of trigeminal nerve. It exits the skull at foramen rotundum. Loss of mandubular sensation is due to mandibular branch of trigeminal nerve which exits the brain at foramen ovale. Loss of muscles of mastication is also caused by damage to trigeminal nerve.
