[The hyoid bone and its preservation in the framework of supraglottic partial resection of the larynx].

BACKGROUND

Whether to remove the hyoid bone as part of the horizontal partial laryngectomy is a question which is discussed controversially. Pathohistological examination of the region involved should help to answer this question.

MATERIAL AND

METHODS

Regarding the involvement of the hyoid bone, 71 surgical specimens of supraglottic carcinoma invading the pre-epiglottic space were studied by whole-organ serial sections.

RESULTS

Only four specimens demonstrated mandatory resection of the hyoid bone because of its proximity to the advancing border of the tumor. In these cases, large tumor masses were palpable directly under the thyrohyoid membrane after the strap muscles had been dissected during the operation.

DISCUSSION: Except for these rare cases in which the tumor was already palpable from outside the larynx, preservation of the hyoid bone during horizontal supraglottic laryngectomy is oncologically safe. It provides a more secure closure of the pharyngotomy and promotes earlier return of the swallowing function because of the maintenance of the normal position of the larynx and pharynx.
