Comparison of Wide Conjunctival Flap and Conjunctival Autografting Techniques in Pterygium Surgery

Abstract

Pterygium is an abnormal fibrovascular tissue extending on the cornea which is a degenerative and hyperplastic disorder. A stromal overgrowth of fibroblast and blood vessels is accompanied by an inflammatory cell infiltrate and abnormal extracellular matrix accumulation. The surgical excision is the main treatment method of pterygium, but recurrence is the most common postoperative complication. In the present study, we aimed to compare the wide conjunctival flap and the conjunctival autografting techniques in pterygium surgery according to time of operation, safety, and effectiveness. Results showed that the effect of wide conjunctival flap techniques on primary pterygium surgery was found close to the conjunctival autograft techniques. In addition, the flap technique has a shorter surgical time, the surgery does not require extreme experience, feeding of the flap is provided with own vessels since the vascular structure is protected on the upper temporal conjunctival area, reverse placement of the flap is not seen, it needs fewer sutures, so that suture disturbances may reduce, and it is less traumatic than autograft technique during conjunctival transport. Therefore, this technique may be preferred in suitable cases.

Comparison of Conjunctival Rotational Flap and Conjunctival Autograft Techniques in Pterygium Surgery

“…There are many 12 Predominantly, most of the studies comparing recurrence rates of free conjunctival autograft and conjunctival flap techniques have reported that results were similar. [16][17][18][19] Our results are in accordance with most of the literature with 6.1% and 6.6% recurrence rates for conjunctival autograft technique and conjunctival rotational flap technique respectively. No severe complication threatening vision was seen among the groups.…”

Comparison of Conjunctival Autograft and Conjunctival Rotation Flap Techniques in Primary Pterygium Surgery

“…11 Aslan with 45 eyes observes rate of recurrence of pterygium following rotational flap surgery and auto conjunctival graft procedure (P=0.46) was comparable. 9 Kim observed statistically similar recurrence rate for auto and rotational flap 8% and 8.6% respectively. 10 By keeping view for future filtration surgery the harvesting site of transplant tissue might be inferior bulbar conjunctiva.…”

“…7,8 Conjunctival autograft transplantation in the form of free or rotational flap is also an effective surgical procedure that reduces the recurrence of pterygium and no statistical significant between two procedures. 9,10 Recurrence of pterygia usually occurs during the first 6 months. 11 Aslan with 45 eyes observes rate of recurrence of pterygium following rotational flap surgery and auto conjunctival graft procedure (P=0.46) was comparable.…”

The results of conjunctivolimbal autograft transplantation in primary pterygium

“…Ancak %24-89 gibi yüksek nüks oranları nedeniyle alternatif cerrahi yöntemler geliştirilmiştir [14]. Günümüzde çeşit-li modifiye cerrahi yöntemler (amniotik membran transplantasyonu, konjonktival otogreft transplantasyonu, konjonktivalimbal otogreft transplantasyonu) ve adjuvan ajanlar (mitomisin-C, 5-florourasil, thio-tepa ve beta radyasyon) kullanılmaya başlan-mıştır [9,10].…”

“…Uzun yıllar uygulanan çıplak sklera ve primer konjonktiva kapatılma-sında oldukça yüksek nüks oranlarına rastlanmıştır [2]. Nüks oranlarını azaltmaya yönelik çeşitli modifiye cerrahi yöntemler kullanılmaya başlanmıştır [9,10]. Bu yöntemlerden konjonktivalimbal otogreft transplantasyonu, pterjium nüks oranlarının (%2-9) ve komplikasyon oluşumunun azaltılmasında en etkili yöntem olarak bildirilmiştir [11,12].…”
