Ideal site for myringotomy and grommet inseion:: (A) Anterior superior quadrant, (B) Anterior inferior quadrant, (C) Posterior superior quadrant, (D) Posterior inferior quadrant
Answer is B. Placement antero-inferiorly compared with placement postero-inferiorly lengthens the time a ventilation tube is in situ. To maximise the duration of potential tube function, the preferred inseion site is anteroinferior through a circmferential or radial incision.
