Interlay Method for Myringoplasty

A Comparative study of the techniques of Myringoplasty - Overlay Underlay & Interlay

“…Eventually the success rate was 83.3% in Overlay, 86.7% in Underlay and 93.3% in Interlay. The results for Interlay technique were in close proximity with the results obtained by komune [13] who observed a success rate of 94.2% for Interlay technique. While guo [14] reported 96.2%, she [22] reported 87.5%, hay and blanshard [16] reported 91% showing high success rate in Interlay Myringoplasty.…”

“…Interlay technique is also considered to be better than Overlay as getting an Interlay plane (Between the fibrous layer and mucosa) is easier and faster than getting an Overlay plane (Between the epithelium and fibrous layer) and having no fear of residual epithelium. The Interlay approach has shown promising results with success rates higher than 90% [13,14,15,16].…”

Endoscope or microscope‐guided pediatric tympanoplasty? Comparison of grafting technique and outcome

“…For TEES tympanoplasty, an interlay technique was preferred for smaller perforations, in which the graft was placed between the squamous and fibrous layers of the pars tensa . When the layers of the tympanic membrane could not be separated, an underlay technique was used; an underlay lateral graft technique was used for larger perforations.…”

“…For TEES tympanoplasty, an interlay technique was preferred for smaller perforations, in which the graft was placed between the squamous and fibrous layers of the pars tensa. 18 When the layers of the tympanic membrane could not be separated, an underlay technique was used; an underlay lateral graft technique was used for larger perforations. For a TEES lateral graft, the meatal skin flap was pedicled superiorly, usually leaving the vascular strip attached to the malleus handle, and the graft was placed under the handle with tabs wrapped around the neck of the malleus and tucked between the skin flap and superior canal wall.…”

Dimensional Stability of the Free Fascia Grafts: An Animal Experiment

“…Perforation of tympanic membrane may not close after surgery in approximately 10% of all the ears subjected to myringoplasty. 1–10 Use of temporalis fascia is reported to result in higher failure rates for larger perforations than for smaller perforations. 11 Among other reasons for this failure, displacement 12 and improper placement of graft 13,14 are also mentioned to be important causes.…”
