| Summary: | Introduction: Ossiculoplasty is one of the commonly done and challenging surgery in otology and
has been done using various graft materials. Materials such as autologous cartilage (tragal or conchal)
or allograft (homograft) of the same tissue and synthetic materials like polyethylene TORP, ceramic
and hydroxyapatite PORP or Titanium prosthesis have been used. But the latter synthetic materials
are expensive and have high extrusion rates. Autologous cartilage grafts are selected for
Ossiculoplasty as they are easy to harvest at the same site of operation, non-toxic, has less extrusion
rate, minimum shrinkage and lateralization. Aims and Objective: The aim of this study is to know
the efficacy of autologous graft and prosthesis in ossicular reconstruction and to evaluate hearing
outcome along with extrusion rate among them. Methodology: It is a prospective study done on
patients attending ENT outpatient department in civil hospital Ahmedabad affiliated to BJ medical
college Ahmedabad. 60 patients were included in the study who underwent ossicular reconstruction
either with canal wall up or down mastoidectomy with tympanoplasty. Conclusion: On follow up of
60 patients over six month we followed there is significant air bone gap reduction with prosthesis but
there is risk of extrusion which cancel out beneficial effect of prosthesis. Whereas cartilage and incus
remodelling give good result in air bone reduction and better take up compare to prosthesis with less
extrusion rate. Also, autologous grafting in ossicular chain reconstruction is economical in developing
countries like India with disease prevalent among low socioeconomic group. |
