A Simple Technique to Obliterate Canal Wall Down Mastoid Cavity Concurrently in Squamosal Otitis Media: Our Experience

AbstractChronic suppurative otitis media is a type of otitis media defined as a long standing infection of a part or whole of the middle ear cleft. Squamosal type of CSOM involves parsflaccida characterised by the formation of cholesteatoma. The present study is retrospective analysis of records of patient who underwent canal wall down mastoidectomy with obliteration of cavity using posteroinferiorly based musculoperiosteal flap with autogenous cartilage and bone pate. Study include patients who underwent canal wall mastoidectomy with cavity obliteration at Tertiary care Hospital Yavatmal, Maharashtra, India; during 2  year period of 2016–2018. 41 patients (42 ears) who underwent canal wall down mastoidectomy with cavity obliteration procedure were included and 06 patients were excluded as they failed to follow up. The outcomes were measured by Marchant et al. grading scale. As per the study it was observed th at 88% (37 out 42 ears) got adequate control of infection with dry cavity, while 12% (5 ears) failed to attain dry ear. So it’s been concluded that canal wall down mastoidectomy is an effective surgical procedure in management of squamosal type of CSOM and mastoid obliteration is proved technique to improve outcomes of canal wall down procedure. Technique used to develop posteroinferiorly based flap to obliterate cavity in our study is simple modification of routine surgical steps commonly practiced by otologist helpful in reducing cavity size and promoting healthy...
