목적: 군날개와 결막이완증이 동반된 환자에서 군날개 수술 시 군날개의 머리뿐 아니라 몸통 부분까지 절제한 후 공막 노출 부위에 결막소판술을 시행하는 경우와 이완결막을 이용한 회전피판술을 시행한 경우 군날개 재발률 및 미용적 측면에 대해 알아보았다. 대상과 방법: 군날개와 결막이완증이 동반된 환자 중 군날개 수술 시 결막소판술을 시행한 환자 27명과 이완된 결막을 이용한 회전피판술을 시행한 21명을 대상으로 후향적으로 연구를 진행하였다. 수술 후 재발은 각막 윤부를 넘어선 경우로 정의하였고, 술 후 미용적인 평가로 수술 부위의 충혈 정도를 Image J 프로그램을 이용하여 빨간색, 녹색, 파란색을 분석한 후, 이 중에서 빨간색의 비율을 계산하여 평가하였다. 결과: 결막소판술 환자군의 평균 연령은 66세이며, 재발률은 5.1%이고 평균 경과관찰 기간은 12개월이었으며, 평균 술 후 5개월에 재발하였다. 회전피판술 환자군의 평균 연령은 62세이며, 재발률은 5.9%이고, 평균 경과관찰 기간은 20개월이었으며, 평균 술 후 5개월에 재발하였다. 결막소판술 환자군에서는 술 전과 비교하여 술 후 빨간색의 비율이 평균 5.3% 감소하였으며, 회전피판술 환자군의 경우 술 후 빨간색의 비율이 평균 6.1% 감소하였다. 두 환자군 사이의 재발률과 수술 전후의 충혈 정도는 유의한 차이는 없었다. 결론: 군날개 환자 중 결막이완증이 병발한 경우 이완된 결막을 이용한 결막 회전피판술(rotational conjunctival flap)은 재발률 및 미용적인 측면에서 유용한 수술 방법으로 생각된다.
Abstract
Purpose: To investigate the differences between the recurrence and cosmesis of the miniflap technique and rotational conjunctival flap technique using redundant conjunctiva tissue in pterygium patients accompanied by conjunctivochalasis. Methods: This retrospective clinical study included 48 patients diagnosed with pterygium and conjunctivochalsis: 27 pterygium patients who underwent surgery using the miniflap technique and 21 pterygium patients who underwent surgery using the rotational conjunctival flap technique with redundant conjunctiva tissue. The recurrence of each operation, defined as fibrovascular invasion of the cornea, was analyzed. Redness was compared using Image J software to resolve the red color ratios with respect to the red, green, and blue colors of the pterygium excision site. The difference in the red color ratio before and after surgery was analyzed with each surgery. Results: For patients who underwent the miniflap technique, the mean age was 66 years, the recurrence rate was 5.1%, the mean follow-up period was 12 months, and the average recurrence was 5 months after surgery. For patients who underwent the rotational conjunctival flap technique using redundant conjunctiva tissue, the mean age was 62 years, the recurrence rate was 5.9%, the mean follow-up period was 20 months, and the average recurrence was 5 months after surgery. The ratio of the red color after surgery decreased 5.3% in the miniflap technique group and 6.1% in the rotational conjunctival flap technique group. Between the two groups, there was no significant difference in the recurrence or redness after surgery. Conclusions: The rotational conjunctival flap technique using redundant conjunctiva in patients with pterygium and conjunctivochalasis was useful for reducing recurrence and cosmesis.
