Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Answer: Meatoplasty.
Step 1: Meatoplasty is the operation that widens the lateral cartilaginous part of the external auditory canal (the meatus), usually done with mastoid surgery to allow proper aeration and self cleaning of the cavity.
Step 2: Compare the distractors. Otoplasty reshapes or repositions the auricle (cosmetic ear surgery). Myringoplasty closes a perforation of the pars tensa of the tympanic membrane. Tympanoplasty repairs a tympanic membrane defect with a graft placed medial or lateral to the annulus, often combined with ossicular reconstruction.
Step 3: Only meatoplasty refers to widening the canal, so it is the answer.
