Abstract

---

Recent advances in optics have provided greater evolution with the concept of minimally invasive surgical procedures, and endoscopic approach allows higher magnification, permitting correct identification of the diseases. Endoscopic surgeries have provided the field of Otology with many endoscopes with varying diameters and acceptable resolution. This technique is suitable for chronic otitis media, malformation of ossicles, traumatic damage, cholesteatoma, otosclerosis, and others. Endoscopic stapes surgery can be attempted in all suspected cases of ossicular malformation, whereas permits a better identification of middle ear structures, facial nerve and stapes area, since traditional techniques may not always be sufficient for diagnostic and surgical management. Additionally, preliminary studies showed a decreased postoperative pain in endoscopic approach when compared with traditional technique. Tympanic membrane tears, temporary facial nerve palsy, perilymphatic gusher, altered taste, dysgeusia and accidental complete cut of the chorda tympani nerve are the possible intraoperative complications. In conclusion, the few available studies have demonstrated that endoscopic stapes surgery is safe and provides similar audio logical results when compared to the microscopic procedures.
