Brief Summary:
In this study, The investigatirs will compare surgical and anatomical outcomes of endoscopic and microscopic tympanoplasty type 1(myringoplasty) using tragal perichondrum and cartilage, and conduct a post-treatment survey regarding:
1. Graft uptake, hearing outcome, postoperative pain, and healing time.
2. Assess the operation time.
1. Graft uptake, hearing outcome, postoperative pain, and healing time.
2. Assess the operation time.
Detailed Description:
Tympanic membrane perforation repair or tympanoplasty is a successful technique and has been validated in numerous studies since Wullstein and Zollner first proposed it in 1952. Previously, the technique was performed with illumination and magnification under a microscope. It typically requires an extensive postauricular incision to get through the narrow and curved external auditory canal, especially in child, complex perforations. The exclusive transcanal endoscopic tympanoplasty technique emerged in the 1990s; it provides more direct and wider surgical viewing angle, and it largely reduces the necessity for a traumatic postauricular incision in difficult cases. It has been gaining ground rapidly in recent years. Although closure rates tympanoplasty surgery can reach 90% or more, higher failure rates are seen in children, larger perforations, chronic Eustachian tube dysfunction, and in bilateral cases. Postoperative improvement in hearing is closely related to the postoperative change in the tympanogram. Postoperative hearing results and tympanograms are mainly influenced by the mucosal condition of the Eustachian tube (ET) orifice. Relatively greater improvement in hearing is observed in the long-term follow- up. Different graft materials have been proposed over the years to improve surgical outcomes, the search for an ideal graft is a subject of continued discussion, as transcanal endoscopic approaches have been proposed for larger and more complex perforations once reserved for postauricular techniques. The temporalis fascia (TF) has been the most preferred graft material for conventional microscopic tympanoplasty via postauricular or endaural approaches; it has theadvantages of having a readily available and plentiful source, and though its durability has been challenged in recent years, it is still widely used. However, with the increasing popularity of transcanal endoscopic ear surgery (TEES), an increasing number of otologists have adopted this technique and switched to using the nearby tragal perichondrium/cartilage graft when the surgical route is changed. The tragus has a pivotal function in reconstruction in ear surgery, and it is limited in source; hence, harvest on an ad hoc basis may lead to donor insufficiency at ensuing surgeries. Moreover, the tragus constitutes the anterior cartilaginous skeleton of the EAM and plays a role in sound transmission; maintaining its integrity would benefit future hearing device applications.
