Clinical observation on horizontal traction in the treatment of severe degenerative lower eyelid ectropion

Abstract

Objective To observe the clinical effect of horizontal stretch of external canthus in the treatment of severe degenerative lower eyelid ectropion. Methods A retrospective clinical case study; 46 cases (68 eyes) of degenerative eyelid were randomly divided into treatment group and control group according to admission order, each for 23 cases (34 eyes). The treatment group underwent lateral canthal level pull operation, the control group underwent resection under the eyelid level, lower eyelid surgery according to the position of shortened lateral canthal ligament length. The location of the lower lacrimal gland, the location of the lower eyelid, the overflow of tears, foreign body sensation and conjunctival congestion after surgery were observed. Results The treatment group of 23 cases (34 eyes) of lower eyelid ectropion correction in 21 days, 2 cases (2 eyes) on the seventh day after surgery for lacrimal punctum ectropion underwent medial fusiform conjunctival resection, postoperative lower eyelid function improved, foreign body sensation, epiphora symptoms subsided. The control group of 23 cases (34 eyes) of lower eyelid ectropion in 21 days was corrected in 14 cases (21 eyes), 5 cases (7 eyes) of lower eyelid function improved, palpebral margin irregular, corneal irritation and affect the appearance of 4 cases (6 eyes) to open and close the lower eyelid could not close to the ocular surface. There was no significant difference between the two groups (P >0.05). There was no significant difference in the lower lacrimal spot and eyelid position between the two groups after surgery: P >0.05. There were significant differences in lacrimal overflow, foreign body sensation and conjunctival congestion P <0.05. Conclusions Adopting the horizontal stretch of external canthus in the treatment of degenerative ectropion would be aimed more pertinently at the primary problem of anatomy, with the advantage of less trauma and quick wound healing, without causing the eyelid defects and improving facial appearance.
