This paper presents our experience with three cases of very unusual impacted foreign bodies in larynx and all without any Classical signs and symptoms of foreign body inhalation. Review of literature reveals that these conditions are rare and reported infrequently. Correct diagnosis and adequate approach is necessary as foreign bodies that do not obstruct the airway and which are stuck in place may be relatively asymptomatic but could be life threatening.Keywords Foreign bodies in larynx Asymptomatic foreign body in airway Transglottic foreign body.

To demonstrate the importance of proper pre operative assessment of laryngotracheal stenosis especially if it acquired one. It also demonstrates the fact that the available treatment modalities for laryngotracheal obstruction can be easily modifi ed as per the clinical presentation for better post operative results. Here we present a case of tracheal stenosis following percutaneous tracheostomy where there was suprastomal tracheal obstruction which was managed in an interesting way to give good post operative results. The obstruction was due to impaction of the fi rst tracheal ring in the stoma which was fused to the posterior tracheal wall. The obstructing tissue was excised and tracheal lumen was established. New tracheostomy was made lower down and the previous stoma was closed. By proper pre operative evaluation and assessment of the unique pathomechanism of stenosis in this case we could operate the above case by simply excicing the obstructing tissue and establishing a lumen instead of resorting to other demanding operations for stenosis of larynx that often lead to complications.
