C. LabyrinthectomyExplanation
Labyrinthectomy is the correct answer because it involves the surgical removal of the labyrinth, which is the inner ear structure responsible for balance and hearing. Severe vertigo can be caused by problems in the inner ear, such as Meniere's disease, which can be treated by removing the affected labyrinth. This procedure eliminates the source of vertigo and can provide relief for the patient. Stapedectomy, myringotomy, and endolymphatic shunt are not appropriate treatments for severe vertigo.Rate this question:

Middle ear ventilation is facilitated by
- A.
Antrostomy
- B.
Mytingotomy
- C.
Stapedectomy
- D.
Turbinectomy
Correct Answer
B. MytingotomyExplanation
Mytingotomy is the correct answer because it is a surgical procedure that involves making an incision in the eardrum to relieve pressure and improve ventilation in the middle ear. This procedure is commonly used to treat conditions such as chronic otitis media with effusion or Eustachian tube dysfunction, which can cause a buildup of fluid or pressure in the middle ear. By creating a small hole in the eardrum, mytingotomy allows for the equalization of pressure between the middle ear and the external environment, promoting better ventilation and reducing the risk of complications.Rate this question:

Correct Answer
D. MastoidectomyExplanation
Cholesteatoma is a condition characterized by the growth of abnormal skin cells in the middle ear. It can lead to hearing loss, dizziness, and recurrent ear infections. Mastoidectomy is the surgical procedure used to remove the infected and damaged mastoid bone, which is often necessary to treat cholesteatoma. This procedure helps to eliminate the infection, prevent its recurrence, and preserve or restore hearing. Tympanoplasty, myringotomy, and stapedectomy are not specifically aimed at treating cholesteatoma and are usually performed for other ear conditions.Rate this question:

Facial nerve trauma can be decreased by use of
- A.
Computerized nerve monitor
- B.
Fluoroscopy
- C.
Berman locator
- D.
Doppler
Correct Answer
A. Computerized nerve monitorExplanation
A computerized nerve monitor can help decrease facial nerve trauma during surgery or other medical procedures. This device is designed to monitor the facial nerve in real-time, providing feedback to the surgeon about the proximity and integrity of the nerve. By using this monitor, the surgeon can make more precise and informed decisions, reducing the risk of accidental damage to the facial nerve. Fluoroscopy, Berman locator, and Doppler are not specifically designed for monitoring facial nerves and may not provide the same level of accuracy and real-time information as a computerized nerve monitor.Rate this question:

- A.
Septoplasty
- B.
Rhinoplasty
- C.
Antrostomy
- D.
Trephination

A. SeptoplastyExplanation
Submucous resection is another term for septoplasty. Septoplasty is a surgical procedure that aims to correct a deviated septum, which is the displacement of the wall between the nostrils. During septoplasty, the surgeon removes or reshapes the cartilage and bone to straighten the septum, improving airflow and reducing symptoms such as nasal congestion. Therefore, septoplasty is the correct answer as it accurately represents the alternative name for submucous resection.Rate this question:
