The duration of nasogastric tube feeding was related to various factors which might contribute to the swallowing function following supraglottic laryngectomy in 38 consecutive cases. The following conclusions appear to have been justified:
1) In the standard technique, the upper part of the thyroid cartilage, the epiglottis, the pre-epiglottic space, the anterior part of the aryepiglottic folds and the false folds are removed, and cricopharyngeal myotomy and approximation of the larynx to the base of the tongue are performed following the removal. This standard procedure usually does not cause serious swallowing problems.
2) Additional removal of the hyoid bone, a part of the base of the tongue and/or the upper part of the vocal fold (s) does not interfere significantly with swallowing.
3) Excision of the arytenoid cartilage causes swallowing problems. When it has to be removed, some reconstructive procedure is required.
4) Asymmetrical removal of the false folds is significantly related to swallowing problems. No explanation for this is available.
