Abstract
The piriform rim can be used for fixation of tubes in sulcus-extension procedures.
The technique has been deseribed. The use of the piriform rim for fixation of sutures
or dentures and for use in other sulcus-extension techniques appears possible and
requires further investigation.
Fixation to the piriform rim was more stable than the use of through-and-through skin
sutures. The tube and flap were pulled toward the ridge in the area of fixation.
Because the tube was fixed to bone, postoperative soreness resulting from movement
of skin sutures was not possible. Esthetically, the internal piriform rim fixation
technique is preferable because it does not require the external skin sutures used
in some techniques.
