Background and Objectives: Besides classical stapedotomy, reverse stapedotomy has been used for many years in the management of otosclerosis. Our study aims to investigate whether reversing the surgical steps in stapedotomy impacts vestibular function and hearing improvement. Materials and Methods: A cohort of 123 patients underwent either classic or reverse stapedotomy procedures utilizing a fiber-optic argon laser. Audiological assessments, following the guidelines of the Committee on Hearing and Equilibrium, were conducted, including pure tone average, air-bone (AB) gap, overclosure, and AB gap closure. Vestibular evaluation involved pre- and postoperative comparison of rotatory test parameters, including frequency, amplitude, and slow phase velocity of nystagmus. Results: The study demonstrated an overall median overclosure of 3.3 (3.3, 5.0) dB and a mean AB gap closure of 20.3 ± 8.8 dB. Postoperative median AB gap was 7.5 (7.5, 11.3) dB in the reverse stapedotomy group and 10.0 (10.0, 12.5) dB in the classic stapedotomy group. While overclosure and AB gap closure were marginally superior in the reverse stapedotomy group, these differences did not reach statistical significance. No significant disparities were observed in the frequency, slow phase velocity, or amplitude of nystagmus in the rotational test. Conclusions: Although not always possible, reverse stapedotomy proved to be a safe surgical technique regarding postoperative outcomes. Its adoption may mitigate risks associated with floating footplate, sensorineural hearing loss, and incus luxation/subluxation, while facilitating the learning curve for less experienced ear surgeons.

A stapes gusher is an alarming situation occurring during stapes surgery for mixed hearing loss. It is characterized by the sudden profuse flow of cerebrospinal fluid in the middle ear and external ear canal after opening the vestibule of the inner ear. An adult patient with unilateral stapes gusher is described; he was operated on both ears with a good hearing result on both sides. The stapes on the side with the cerebrospinal fluid leak was malformed, especially in the posterior crus--a finding which may suggest the possibility of a stapes gusher. The small-hole stapedotomy is a safe technique when dealing with a profuse cerebrospinal fluid leak, and it enables the closure of the leak with additional tamponade of the oval niche and the achievement of a good hearing result.
