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.
