Abstract

Objective: The objective of this study is to investigate the healing effects of topical dexpanthenol on traumatic tympanic membrane perforation in rats through observations of microscopy examination and histological changes. Material and Methods: 24 male Spraque-Dawley rats divided into 4 groups. Group 1; without treatment, only the tympanic membrane examined. The other three groups tympanic membrane were perforated with a 0.8 mm perforator, Group 2; no topical agent was applied, only perforated, Group 3; treated with saline solution (sham group) and Group 4; treated with topical 500 mg dexpanthenol in liquid form. Saline solution and dexpanthenol applied at after perforation, 24, 48, 72, and 120 hours after the myringotomy. Otomicroscopic examination under anesthesia was performed on the fifteenth day to check the status of the myringotomy patency on each side. The healing, calcification and of tympanic membrane perforations was evaluated. Results: In Group 4, all the membranes were closed without calcification. Histological examination is thickening in the membrane connective tissues compared to normal was observed in all groups. Degenerative fibroblasts and irregularities in collagen fiber distribution were detected in the decspanthenol group according to other groups. Conclusion: In the direction of these findings, traumatic membrane perforation in the rat model is thought to be an effective treatment modality in the development of topical dexpanthenol perforation closure and myringosclerosis.

Özet

Amaç: Sıçanlarda travmatik kulak zarı perforasyonu oluşturarak, topikal dekspantenolün iyileşme üzerine etkisinin mikroskobik ve histolojik olarak incelenmesidir. Gereç ve Yöntemler: Yirmidört erişkin, erkek, Spraeque-Dawley ırkı rat, eşit şekilde dört gruba ayrılmıştır. Grup 1; işlem yapılmamış, sadece kulak zarı incelenmiştir. Diğer üç grubun kulak zarında 0,8 mm perforasyon oluşturulmuştur. Grup 2; sadece perforasyon işlemi uygulanmış, Grup 3; serum fizyolojik damlatılmış (shamgrubu), ve Grup 4’e; topikal 500 mg dekspantenol sıvı formu, perforasyondan hemen sonra, 24, 48, 72ve 120. saatlerde uygulanmıştır. On beşinci günde anestezi altında, otomikroskobik inceleme yapılarak her iki zarda kapanma, kalsifikasyon oluşumu ve histolojik değişiklikler değerlendirilmiştir. Bulgular: Grup 4’te diğer gruplara göre kalsifikasyon ve perforasyon gözlenmemiş ve diğer gruplarlakarşılaştırıldığında istatistiksel olarak anlamlı sonuçlar elde edilmiştir. Histolojik bulgularda, tümgruplarda zar bağ dokularında normal zara göre kalınlaşma, dekspantenol grubunda diğer gruplaragöre dejeneratif özellik gösteren fibroblastlar, kollajen lif dağılımında düzensizlikler saptanmıştır.Sonuç: Bu bulgular doğrultusunda, topikal dekspantenolün travmatik zar perforasyon kapanması vemiringosklerozun önlenmesinde etkili bir tedavi yöntemi olabileceği düşünülmektedir.
