THE TRANSTYMPANIC technic may be regarded as a new method in surgical otology. Its object is to make directly accessible the tympanic structures anterior to the mastoid process, as well as the mastoid process and its contents. The anterior structures are the attic, aditus, tegmen, vestibuloampullary region, facial canal, round window, promontory, tympanum and hypotympanum, as well as the forward extension of the hypotympanum into the eustachian tube and the muscular canal containing the tensor tympani. The posterior structures include the mastoid process, the genu and the descending part of the facial canal, lateral sinus, semicircular canals and the tegmen.
Certain procedures are greatly facilitated by the use of the transtympanic approach, and, indeed, some of them can be carried out only by this route. Details of transtympanic atticoantrostomy and fenestration have already appeared in appropriate journals; publication of the other procedures will follow.
