The technique and application of individualized tympanic membrane flap in the repair of tympanic membrane under endoscopy ear surgery
Objective:To investigate the technique of personalized flap making under otoscopy and its clinical application.Methods:The clinical data of patients who underwent 301 Military Hospital myringoplasty in the De-partment of otoendoscopic surgery,Department of Otorhinolaryngology,head and neck surgery,Department of Otorhinolaryngology,from October 2022 to 2023 August were analyzed retrospectively,all enrolled patients were performed independently by the same skilled otoendoscopic surgeon.The patients'general condition,medical his-tory,tympanic membrane perforation scope,perforation size,need for tympanic cavity exploration,thickness of skin flap,tympanic cavity lesion scope,skin flap making method and postoperative rehabilitation were collected.Results:Many factors such as the location of tympanic membrane perforation,the thickness of the skin flap,the degree of curvature or stricture of the ear canal and the extent of the lesion in the tympanic cavity should be consid-ered in the manufacture of the individualized tympanic membrane skin flap,the way of skin flap making does not affect the long-term postoperative rehabilitation,but it can effectively avoid unnecessary ear canal skin flap injury and improve the operation efficiency.Conclusion:Scientific flap fabrication is important for improving surgical ef-ficiency and enhancing surgical confidence.
