A styloid process (SP) cutter was developed and put into clinical use. The design of components of the ‘styloidectome’ was based on the principles of mechanics. The measurements of the individual parts were determined on the basis of morphological data of the oropharynx from 40 subjects undergoing tonsillectomy under general anaesthesia. Experiments showed that the instrument could be used to transect the SP and excise the amputated bones from the deep tissue space. We used the instrument for the resection of elongated SPs, via an oral approach, in seven in-patients (involving 10 SPs) under general anaesthesia and in two out-patients (involving three SPs) under local anaesthesia. The length of the resected SP ranged from 0.8 to 2.5 cm and the stump of the SP was smooth. The removal lasted only seconds and blood loss was minimal, without any complications. The styloidectome was reliable, easy to use and could be used for the resection of an elongated SP under general or local anaesthesia.
