The author of one of the Hippocratic treatises, according to circumstances, recommends sawing it out, consuming it with septics, tying it with a ligature, and burning it with a red-hot iron. (De Morbis, ii.) In the ‘Isagoge’ of Galen, it is merely recommended to cut out the tumour, and to scrape its roots. Celsus, like our author, recommends excision with a sharp instrument of iron, and directs us to apply afterwards to the part a tent smeared with some styptic. A proper dressing is then to be applied for cleansing the sore. (vii, 10.) Oribasius briefly mentions excision as a proper remedy when medicines fail. Albucasis describes minutely the operations of excision and sawing out the tumour. Like our author, he directs us to seize the tumour with a hook, to pull it down, and cut it out. If any part remain, he recommends us to scrape it out with a slender instrument, and then to apply styptics, such as vinegar, water, or snow. The operation of sawing it out with a thick knotted thread is minutely described by him. He also speaks of cauterizing the part from which the tumour has been removed. Mesue describes the process of sawing out the tumour, with some slight differences. He recommends us to use three horse-hairs, which, being tied together with knots, are to be introduced into the nose with a leaden needle, and one end conveyed out by the openings of the palate; and then, by pulling at both ends, the tumour is to be sawed out. Avicenna, Haly Abbas, and Rhases make mention of excision and the process of sawing out the tumour. Rhases relates the history of a case of polypus, unusually large, which he had seen extracted in an hospital. He and Albucasis recommend the part to be dressed with green ointment. The veterinary surgeons appear to have depended principally upon the actual cautery. See Vegetius (Mulom. ii, 38.) The method of curing polypi of the nose, by sawing them out, seems to have now fallen completely into disuse, whether deservedly or not we cannot, from our own experience, venture to decide. Fabricius ab Aquapendente disapproved of it; but he was evidently much prejudiced in favour of the operation with a new forceps of his own invention. (Œuv. Chir. ii, 24.) Sprengel informs us that this method was practised by the surgeons of the middle ages. It is described by Brunus (Chir. Mag. ii.) Sprengel thus explains the other operation described by our author: “Il se servait d’un instrument particulier auquel il donnait le nom de σπάθιον πολυπικὸν et qui était garni à l’une de ses extrémités d’un ciseau, κυκλίσκος” (Hist. de la Méd. viii, 4.) Why does he substitute κυκλίσκος for κυαθίσκος? That the instrument had a chisel (ciseau) at its extremity is altogether improbable, and this supposition is unwarranted by the context. Κυαθίσκος means the cup-like or concave end of the instrument. SECT. XXVI.—ON MAIMED PARTS.
