Ligation of the carotid artery is necessaryonly when, in spite of the repeated application of the thermo-cautery, the growths recur. Dupuytren, Mussey and Wein-lechner have obtained cures from this operation. B. In the External Auditory Canal and in theMiddle Ear. Aural Polypi. The pedunculated, connective-tissue growths in the ear, knownas polypi, arise most frequently on the mucous membrane of themiddle ear, more rarely in the external auditory canal and onthe membrana tympani. They usually develop in the courseof chronic, less ^frequently acute, middle-ear suppuration, or a d.

Polypiare more frequently situated on the membrana tympani than wasat one time supposed. The most frequent points of origin of polypi of the middleear are the inner and inferior walls of the tympanic cavity, thecovering of the ossicles, and the external attic; more rarely thecells of the mastoid process, and the mucous membrane of theEustachian tube. In the external auditory canal the roots ofthe polypi spring mostly from the posterior superior wall of theosseous meatus, in the neighbourhood of the membrana tympani,and partly on the latter itself; rarely in the cartilaginous in the external auditory canal develop either from the 62
