- Otoplasty
- Myringoplasty
- Tympanoplasty
- Meatoplasty
Show Solution
The Correct Option is D
Solution and Explanation
Word root angle: match the suffix to the structure.
Meatus means the canal opening, so meatoplasty is the surgery to widen the lateral cartilaginous external auditory canal, commonly performed during canal wall down mastoidectomy to keep the cavity ventilated and easy to clean.
Run through the others to confirm: otoplasty (oto, ear) reshapes the visible auricle for cosmesis; myringoplasty (myringo, drum) seals a hole in the pars tensa; tympanoplasty repairs the tympanic membrane and middle ear with a graft. None of these touch the canal width. The procedure that widens the canal is meatoplasty.
