Intraoperative and Postoperative Advantages of two Absorbable Materials for Supporting Graft in Endoscopic Tympanoplasty: Oxidized Regenerated Cellulose (Surgicel(®)) Over Gelatin Sponge (Spongostan(®)).

内容摘要

To compare the intraoperative and postoperative outcomes of using oxidized regenerated cellulose (Surgicel&#xae;) versus absorbable gelatin sponge (Spongostan&#xae;) for supporting graft material in endoscopic tympanoplasty. We retrospectively analyzed 92 patients who underwent endoscopic type 1 tympanoplasty between 2020 and 2024. Patients were divided into 2 groups based on the supporting graft material used: 47 received Surgicel&#xae; and 45 received Spongostan&#xae;. Primary outcome measures included intraoperative hemostasis quality, duration of graft placement, postoperative graft success, graft lateralization, and hearing outcomes at 6 and 12&#x2009;months. Hemostasis during graft placement was better in the Surgicel&#xae; group (P&#x2009;=&#x2009;.017), and shorter graft placement duration was observed (P&#x2009;=&#x2009;.047). At&#x2009;&#x2265;&#x2009;6&#x2009;months, graft success rates were comparable between the groups (89.4% for Surgicel&#xae; vs 82.2% for Spongostan&#xae;; P&#x2009;=&#x2009;.380). However, graft lateralization was significantly less frequent in the Surgicel&#xae; group (2.1%) compared to the Spongostan&#xae; group (15.6%; P&#x2009;=&#x2009;.029). While the Spongostan&#xae; group showed significantly better hearing results at 6&#x2009;months (mean ABG 16.9&#x2009;dB vs 28.6&#x2009;dB; P&#x2009;<&#x2009;.001), hearing outcomes were similar by 12&#x2009;months. Both Spongostan&#xae; and Surgicel&#xae; are effective supporting graft materials in endoscopic tympanoplasty. However, Surgicel&#xae; was associated with certain intraoperative advantages, including superior hemostasis and shorter operative time, along with a significantly lower risk of postoperative graft lateralization. These benefits suggest Surgicel&#xae; may be a preferable option for enhancing surgical efficiency and optimizing outcomes in endoscopic ear surgery.
