tion of a silver wire, and twisting of the free ends from 

 day to day. Bassini's, for the radical cure of inguinal 

 hernia ; the sac is exposed, twisted, and the neck li- 

 gated and removed ; the spermatic cord is lifted, and 

 the border of the rectus is stitched to the edge of the 

 internal oblique, the transversalis muscle and the trans- 

 versalis fascia to Poupart's ligament under the cord. 

 The cord is placed upon this layer and the border of 

 the external oblique is stitched to Poupart's ligament 

 over the cord. Bates', for internal urethrotomy ; a 

 special urethrotome is used to divide the stricture from 

 within outward. Battey's (A'.), for oophorectomy ; 

 also called "normal ovariotomy ;" removal of the 

 ovaries in order to eliminate their physiologic influ- 

 ence. Bauden's : I. For amputation through the 

 foot ; it is made at the tarso-metatarsal joint, disartic- 

 ulating the first metatarsal bone, and sawing through 

 the remaining ones on a level with the internal cunei- 

 form bone. 2. Y ox amputation at the knee-joint; by 

 oval anterior and posterior flaps. 3. For excision of 

 the shoulder ; by a single anterior vertical or oblique 

 incision. Baum's, for stretching the facial nerve ; 

 an incision is made downward and forward from be- 

 hind the ear, about opposite the meatus, to a point 

 immediately below the lobule, and then prolonged 

 nearly to the angle of the jaw, a small, transverse 

 incision being also made below the pinna. Bayn- 

 ton's, a method of healing leg-ulcers ; it is the original 

 method of applying adhesive straps and a bandage in 

 cases of indolent ulcers. Beaufils', for uranoplasty ; 

 a single flap is twisted on itself so as to fill up the 

 aperture. Beclard's, for amputation at the hip-joint ; 

 a modification of Liston's amputation, by cutting the 

 posterior flap first. Beer's : I. For cataract ; ex- 

 traction by the flap-method. 2. F 'or iridectomy ; an 

 incision is made near the margin of the cornea with a 

 lance-knife entered perpendicularly, then made parallel 

 with the plane of the iris, making a section concentric 

 with the cornea, of the desired length. 3. For irido- 

 dialysis. The same as P/imly's operation. Begin's, 

 for excision of the knee. Similar to Textor' 's operation, 

 q.v. Bell's (C.) : I. For gastrotomy ; a parietal 

 incision is made in a line extending from the umbilicus 

 toward the left false ribs. 2. F 'or ligation of the first 

 part of the lingual artery ; the same incision is used 

 as in the operation of election, its center being oppo- 

 site the body of the hyoid bone. Belmas' (M.), for 

 the radical cure of inguinal hernia; it consists in in- 

 troducing gold-beaters' skin in the neck of the sac, to 

 excite sufficient inflammation. Benham's, for hem- 

 orrhoids ; the same as Pollock's operation, a. v. Ben- 

 nett's ( W. //.), for varicocele; a modification of 

 Hoivse 1 s operation, in which the elongated cord is 

 shortened. Benson's, for entropion ; a modification 

 of van Millingen 1 s operation, in which a flap of 

 mucous membrane is taken from the lower lip. 

 Bent's, for excision of the shoulder ; a flap is taken 

 from the deltoid region, with the base inward, by means 

 of one vertical and two transverse incisions. Berard's 

 (A.), for naso-pharyngeal tumor ; an incision is made 

 either along the median line or the side of the nose, ex- 

 tending down through the upper lip ; by means of the 

 cutting-forceps the outer wall of the nasal cavity and of 

 the antrum is removed. Berger's {P. ) ,for interscapttlo- 

 thoracic amputation ; it is made by two flaps — an an- 

 tero-inferior or pectoro-axillary flap, and a postero- 

 superior or cervico-scapular flap. Von Bergmann's 

 (£. ) : I . For hydrocele ; excision of the parietal part of 

 the sac. 2. For mastoid and middle- ear disease ; it con- 

 sists in making a long, crescentic incision from above 

 and in front of the auricle, backward and downward, 

 and then loosening the periosteum from the entire osse- 



ous auditory canal ; the bony portion between the audi- 

 tory canal and the middle cranial fossa is penetrated 

 with a chisel as far as the bony annulus tympanicus, and 

 the incision is then carried backward toward the mas- 

 toid process, avoiding injury of the facial canal ; there 

 is then inserted a tamponade of iodoform-gauze. j 

 For nephrectomy ; a lateral lumbar incision is made 

 from the upper end of the twelfth rib obliquely toward 

 the junction of the outer and middle thirds of Poupart's 

 ligament. Berlin's: I. For entropion; incision 

 through the entire thickness of the lid, parallel to the 

 ciliary margin, and excision of a portion of the tarsus 

 and conjunctiva. 2. For excision of the lacrymal sac ; 

 the same as Platner's operation, a. v. Berling- 

 hieri's, for entropion and trichiasis ; a horizontal inci- 

 sion is made along the margin of the lid, a vertical 

 incision from each end of this, away from the margin, 

 followed by dissection up of the flap, and extirpation 

 of the hair-bulbs ; the flap is then replaced. Bernays' 

 (A. C.) , for gastrotomy ; removal of the growths bulg- 

 ing into the cavity of the stomach by the curet or othei 

 instrument, after making an incision through the wall 

 of the stomach. Bernheim's, for circumcision ; the 

 operation is performed with the galvano-cautery instead 

 of the knife. Berthold's. See under Myringoplastic. 

 Bigelow's [H. J.), for vesical calculus ; the ordinal] 

 operation of litholapaxy, q. v. Billroth's ( T. ) : I. Foi 

 blepharoplasty ; a modification of Diefen/ach's opera- 

 tion, q. v. 2. For ectopia vesica ; a modification of 

 Thiersch's operation, in which two broad, lateral 

 doubly-pedunculated flaps are dissected up. 3. Foi 

 excision of the tongue ; a curved, submental incision i- 

 carried backward along the lower border of the ja« 

 on both sides ; the bone is then divided in two places, 

 and after excision of the tongue, is replaced. 4. Foi 

 genu valgum ; incomplete linear osteotomy of the 

 tibia. 5. For naso-pharyngeal tumor ; an incision 

 from the root of the nose to the tip is carried into the 

 nostril. An incision from either end of this is carrier 

 horizontally across the cheek. The nose is separatee 

 in the line of the first incision, and the superior max 

 ilia is sawn through in the line of the second and thirt 

 incisions, and the bone pried out of place, hinging] 

 upon the pterygoid process. 6. F'or ovariotomy ; thej 

 pedicle is ligated between two forceps, and therj 

 divided with the thermocautery. 7. For pylorectomy , 

 a parietal incision is made in almost a transverse direc I 

 tion ; the divided walls of the stomach and bowel an{ 

 brought together and united by sutures on the side of: 

 the greater curvature of the stomach. 8. F'or reset j 

 tion of the intestine ; when the segments of the intes j 

 tine are of unequal size, one end is closed by suture; 

 and the other end implanted into a slit made in the 

 long axis of the bowel. Bird's (G.) : 1. 1 

 of the knee ; the patella is sawn through tran 

 to reach the joint, and the two fragments are brough'l 

 together afterward with sutures. 2. F'or jejunostm) 

 an oblique incision is made in the same position as ir 

 pylorectomy ; the transverse colon is drawn upward 

 and the omentum is pushed to the left and the bowel at 

 tached to the margin of the parietal wound, and opene< 

 after adhesions have formed. 3. Osteotomy forextren 

 Jlat-foot ; resection of a wedge of bone (the scaffco 

 alone, or the scaphoid and the head of the astragalus 

 from the inner side of the foot. 4. For the 

 new-growths of the tonsil ' ; a modification ot ( hem 

 operation in which the second incision is made througl j 

 the cheek, from the angle of the mouth to tin 

 lower jaw. BischofFs, for laceration of : 

 perineum ; a denudation is made similar to that BU ; 

 in Frennd's operation, except that the tongue ol v « 

 ginal tissue left in the median line is narrov
