Eustachian tuboplasty.

Until recently a practical method of reconstruction of the osseous Eustachian tube, stenosed by bony or connective tissue, was yet to be evolved. This paper recommends a new surgical procedure illustrating the possibility of reaching the isthmus of the Eustachian tube by way of a combined transcanal and preauricular approach. After initial cadaveric dissections the basic surgical anatomy was worked out in two rhesus monkeys. Subsequently within the duration of one-and-a-half years two cases of osseous Eustachian tube stenosis have been managed successfully with no post-operative complication.
