Eustachian Tube Dysfunction in 2 patients with localized Amyloidosis of the Nasopharynx and Eustachian Tube
18 April 2018 (online)
Few cases of localized amyloidosis of the upper aerodigestive tract have been reported in literature.
We present two cases of dilatory Eustachian tube dysfunction caused by localized nasopharyngeal amyloidosis.
Management and Outcome:
Diagnostic biopsies confirmed AL-amyloidosis of the Nasopharynx and Eustachian Tube protuberance. Both patients had undergone earlier treatments with grommets. Balloon dilation of the Eustachian tube was performed. The symptoms recurred in long-term follow-up.
Localised nasopharyngeal amyloidosis can be a rare cause of refractory Eustachian tube dysfunction and middle ear effusion. Histopathology has to confirm the diagnosis. Treatment options include grommets and balloon dilation for symptom control.
