Annular wedge tympanoplasty

Comparative study of efficacy of graft placement with and without anterior tagging in type one tympanoplasty for mucosal-type chronic otitis media

“…There is also delayed healing due to the lack of residual tympanic membrane and a resulting lack of nourishment of the graft tissue. 21,22 Another factor contributing to failure of the underlay technique is inadequate anchorage of the graft due to improper insertion into the external auditory canal wall, with resulting graft medialisation. 16,23 The presence of an anterior bony overhang also makes it difficult to visualise and repair anterior perforations.…”

“…16,21 Some authors have suggested the use of a combination of overlay and underlay grafting methods, in order to achieve better results in cases of anterior and subtotal perforation. 16,21,22 An anteriorly based flap has also been described for the repair of anterior perforations. 23 However, these methods carry a risk of anterior blunting.…”

“…The greater incidence of reperforation in patients with anterior and subtotal perforations may be due to reduced vascularity of the anterior aspect of the tympanic membrane compared with the posterior, with a greater risk of necrosis and reabsorption of the graft material. There is also delayed healing due to the lack of residual tympanic membrane and a resulting lack of nourishment of the graft tissue 21 , 22 . Another factor contributing to failure of the underlay technique is inadequate anchorage of the graft due to improper insertion into the external auditory canal wall, with resulting graft medialisation 16 , 23 .…”

Cartilagem tragal com pericondrio em timpanoplastias

“…Esses estudos mais recentes mostram que o enxerto de cartilagem, quando comparado a outros tipos de enxerto, não apresenta diferenças estatisticamente significantes quanto ao nível de audição e inclusive entre sexo e/ou idade. Além disso, também tem mostrado quase 100% de sucesso no fechamento da caixa timpânica 2,5,11,13 .…”

Ten years’ experience with Felix tympanoplasty: analysis of anatomical and functional results

“…A key point is the vibrating anterior tympanomeatal angle, where scarring or blunting are frequent complications 5 . To overcome these problems, we propose the Felix tympanoplasty, a modification of the annular wedge tympanoplasty developed by Pappas and Sympson in 1984 and published in 1992 6 …”
