A case of
anatomical variation of the hyoid bone in a girl is presented. Over-extended
bending of the elongated and curved right side of the hyoid bone, may project
to the lumen of the supraglottic area as the patient presented. She had a
foreign body sensation in her throat, and on fiber optic laryngeal examination, a bulge’s appearance as a “third arythenoid”
was seen. We present the clinical finding and the picture of a “third arythenoid” with literature review.
