For the correction of partial ectropion a V-shaped incision is made on the lid with the base of the triangle, including the maximum eversion, as in Fig. 89, _a_. [Illustration: FIG. 90_a_.—CORRECTION OF PARTIAL ECTROPION. (Author’s case.)] The incisions are made downward from the tarsal border, just below the lashes, and converge to a point. The flap included therein is carefully dissected up, dividing all the scar adhesions, and is pushed upward until the tarsal border at the seat of the defect is overcorrected in this position. The incisions are united with No. 1 twisted-silk structures to form the letter Y, as shown in Fig. 89, _b_. As the lid has usually become elongated from prolonged eversion, a small, triangular piece of skin may be excised at the outer end of the lid, with its base turned upward. In bringing the two sides together in linear form, horizontal traction is made along the tarsal line, which aids much in bringing about the desired result. In the case shown in Fig. 90_a_ the ectropion was the result of the application of nitric acid or caustic potash for the removal of a nevus. It was corrected by the method just described, the result being shown in Fig. 90_b_. [Illustration: FIG. 90_b_.—CORRECTION OF PARTIAL ECTROPION. (Author’s case.)] COMPLETE ECTROPION =Dieffenbach Method.=—In complete ectropion the entire lid between the canthi is included in the V-shaped incision just mentioned (Fig. 91) and the flap is sutured as shown in Fig. 92. In crowding up the detached flap the palpebral border must be overcorrected, since the contractions following union will reduce the effect even to the extent of necessitating later minor operations. [Illustration: FIG. 91. FIG. 92. COMPLETE ECTROPION, DIEFFENBACH METHOD.] To prevent this contraction the palpebral fissure may be united after the correction is made by fine sutures, which are removed in several weeks (Plessing). This is rather uncomfortable for the patient, but there is no question as to the efficacy of the method. A shield can be worn over the eye operated upon after the incisions have united until the lids are separated. This relieves the discomfort of the patient to some extent, while the constant conscious strain to open the eye is greatly overcome by the mere knowledge of the presence of the shield. If the position, or the extent of the deformity, does not permit of the Dieffenbach method, the following may be employed: =Wolfe Method.=—An incision is made parallel to the tarsal border just below the lashes. The scar tissue is then excised. The palpebral fissure is closed by several sutures, as already described, thus drawing up the everted portion and bringing the lids together and causing a large, open wound (Fig. 93).
