Abstract
Background: A tympanolith is a calcified body found impacted in mucosa of the middle ear. It is thought to be intrinsic
deposition of calcium over a nidus of mucous plug whereas a foreign body is usually extrinsic.
Case Report: A young male with bilateral ear inactive chronic mucosal type of otitis media was posted for tympanoplasty. A
full cuff incision and exploration of ear showed a smooth gritty hard stone stuck in the hypotympanum later confirmed to be a
tympanolith. Middle ear anatomy of hypotympanum was studied with straight and angled endoscope. A type A configuration of
bony crest of Protiniculum was found to be the reason for formation of mucus plug and lith.
Discussion: Tympanolith is a rare condition which is known to occur in a chronically discharging ear, due to calcium deposition
on a mucus plug or biofilm formation. Tympanolith is a bony crest in hypotympanum with variable anatomy.
Conclusion: Every nook and corner of the middle ear should be inspected while doing a tympanoplasty to rule out tympanolith,
foreign body or granulations. Either a full cuff incision microscopic tympanoplasty or an inspection of middle ear by angled
endoscope in every case are suggested options.
