The first naso-sinus laboratory for cadaver preparation in Thailand.

The first naso-sinus laboratory has been set up in Siriraj Hospital for better training of rhinosurgeons. The specimens used for practice operation are the entire nasal cavities with all paranasal sinuses, taken from cadavers and preserved in 95% ethanol. The "Siriraj" sinus holder is specially designed and constructed to hold various sizes of specimens. It is made of plastic board and stainless steel screws; it is an inexpensive and simple device which can be afforded by every centre. With this naso-sinus laboratory, ENT residents and rhinosurgeons can achieve their skills in performing nasal endoscopy, endoscopic or microscopical sinus surgery and all kinds of sinus operations at their convenience.
