<prompt> Ideal site for myringotomy and grommet inseion:Anterior superior quadrantAnterior inferior quadrantPosterior superior quadrantPosterior inferior quadrant  <response>: 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.
