Tracheoplasty 625 



When a fissure occurs in the cervix at time of parturition, 

 the injury commonly passes unseen until faulty healing has 

 occurred with a troublesome cicatrix. Sometimes the seri- 

 ousness of the cervicitis is caused by the imprudent use of 

 the scalpel to overcome dystocia falsely diagnosed as being 

 due to atresia or stricture when in fact the cervix is normal 

 and fails to dilate because the uterus is atonic owing to the 

 presence of infection. In such instances there is often a 

 false impression of recovery, the cervix healing with a bad 

 cicatrix which invites serious cervical infection. 



Numerous cases of severe cervicitis without a history of 

 fissure or incision, which will not yield to the application of 

 disinfectants, demand for satisfactory handling surgical in- 

 terference. 



Tracheoplasty 



Tracheoplasty is indicated in refractory cervicitis and 

 when there are structural changes which cause sterility, 

 either directly or by reason of such lesions as cause the cer- 

 vix to be more prone to disease. Tracheoplasty in itself 

 plays little part in cervical surgery of the cow, but certain 

 plastic procedures, intrinsically involved in all cervical sur- 

 gery, play a very important role in the attaining of satis- 

 factory results. Tracheoplasty is intended to restore the 

 cervix as nearly as possible to its normal morphology and 

 tissue condition. Since most of the cases of cervicitis 

 result directly from injury or from the succeeding inflam- 

 mation, the subject is largely covered under succeeding 

 heads. Where there is an inflammatory process of the mu- 

 cosa and muscular walls, it has been my experience that a 

 simple tracheoplastic operation does not give satisfactory 

 results and in its stead a partial trachelectomy should be 

 performed. 



A marked hypertrophy or elongation of one cervical lip 

 may call for amputation of this portion. In this case a cir- 

 cular incision is made through the mucosa around the base 

 of the elongated lip, and at either side of the base an in- 

 cision is directed at such an angle into the fibromuscular 

 tissue that they converge to excise a wedge-shaped piece of
