Abstract

Objective:To investigate the healing effects of topical dexpanthenolon acute tympanic membrane (TM) perforations in rats through observations of healing time and histopathological changes. Methods:A total of 20 Sprague-Dawley rats were included in thestudy. Every perforation was formed at the pars tensa of TMs with a size2 mm in diameter. The right TM of each rat was treated with topicaldexpanthenol for 2 days (treatment group); on the other hand, no topical agent was applied on the left TMs of rats (sham group). All TMswere examined under otomicroscopy at the third, fifth, and seventh daysto determine the healing of TM perforations. Moreover, TMs werehistopathologically examined to assess neovascularization, collagenization, fibroblastic activity, inflammatory cell positivity at the lamina propria (LP) layer of TMs. Results: The TM perforations in the treatment group healed significantly earlier (p<0.05). The collagenization at LP was significantlyhigher in the treatment group (p<0.05), while neovascularization andinflammatory cell positivity were significantly higher in the sham group(p<0.05). The fibroblastic activity was higher in the treatment groupalthough no statistically significant difference was determined. Conclusion:The findings of the current study suggest that dexpanthenol may accelerate the healing of acute TM perforation.

Özet

Amaç: Bu çalışmanın amacı, sıçanlarda akut kulak zarı (KZ) perforasyonunda topikal dekspantenol uygulamasının iyileştirici etkilerini iyileşme süresi ve histopatolojik değişikliklerin gözlenmesi ile araştırmaktır. Yöntem:Yirmi adet Sprague-Dawley cinsi sıçanın her iki KZ'ninpars tensa bölgesinde 2 mm genişliğinde perforasyon oluşturuldu. Sıçanların sağ kulaklarındaki perforasyonlar (tedavi grubu) 2 gün boyunca topikal dekspantenol ile tedavi edildi. Sol kulaklara (sham grubu) hiçbir topikal tedavi verilmedi. Kulak zarı perforasyonlarının kapanma durumunu değerlendirmek için sıçanlar üçüncü, beşinci ve yedinci günlerde otomikroskopi ile değerlendirildi. Histopatolojik olarak kulak zarları, lamina propria tabakasındaki neovaskülarizasyonu,fibroblastik aktiviteyi, inflamatuar hücre pozitifliğini ve kollajenizasyonu değerlendirmek için incelendi. Bulgular:Tedavi grubunda KZ perforasyonları istatistiksel olarak anlamlı düzeyde erken iyileşti (p<0.05). Lamina propria kollajenizasyonutedavi grubunda anlamlı derecede yüksek bulunurken (p<0.05), neovaskülarizasyon ve inflamatuar hücre pozitifliği tedavi verilmeyen grupta anlamlı derecede yüksekti (p<0.05). Fibroblastik aktivite tedavi grubundadaha yüksek bulunmasına rağmen fark istatistiksel olarak anlamlı değildi.Sonuç:Bu çalışmanın bulguları, akut kulak zarı perforasyonun iyileşmesini hızlandırmada dekspantenolun etkin olduğunu göstermektedir.
