Rosen aural speculum

This aural speculum was designed by Rosen the renowned otologist. It is partially slotted where the slot does not extend up to the tip of the speculum. The slot extends to up to 3/4 the length of the speculum. The absence of slot close to its tip helps the speculum to snugly fit into the external auditory canal. It also straightens the external canal making the tympanic membrane visible to the surgeon.

The presence of slot helps the surgeon to infiltrate local anesthetic medicines to the external auditory canal. This speculum should be introduced only up the cartilaginous portion of the external canal. It should not touch the bony portion of the external auditory canal.

Uses:

  • During ear surgeries to straighten the external auditory canal and make the ear drum visible
  • To remove wax and desquamated epithelial debris from the external auditory canal
  • To perform surgeries like myringotomy, myringoplasty and stapedectomy
