“…He noted that the wavelength of the argon laser allowed passage through the labyrinth and postulated that this could be protective to the labyrinth as opposed to the CO 2 laser, which was predicted to risk boiling perilymph on exposure to an open vestibule. Wilpizeski 85 disagreed with these concepts and believed the CO 2 could be useful and safe in otological surgery.…”

Objective: To improve the techniques required to perform a stapedotomy without prosthesis (stapedioplasty). Study Design: New infrared lasers were evaluated for potential use in otological surgery in guinea pigs. A prospective human trial of 34 primary stapes operations using the Argon ion laser was performed, with 11 stapedioplasties and 23 conventional stapedotomies as controls. Methods: Laser-tissue interactions were evaluated for temporal bone and live guinea pig tissues, measuring crater histology and labyrinthine temperature elevations. Patients undergoing stapedioplasty had Argon ion laser cuts with endoscopic assistance made in the anterior crus and footplate to mobilize the posterior segment of the stapes while the anterior portion remained fixed. Results: Diode laser (808-nm) vaporization craters and temperature elevations in the vestibule were suitable for clinical use. Overall, stapedioplasty patients' hearing was improved with air-bone gap closure to a mean of 8.3 dB (SD ؎ 9.8 dB). Conclusions: Patients with anterior footplate otosclerosis are candidates for stapedioplasty preserving the annular ring and stapes tendon and eliminating prosthesis complications. High-resolution small endoscopes, coupled with Argon ion or diode lasers promise to improve stapes visualization, enhancing the ability to perform minimally invasive surgery on the stapes footplate.
