Sodium hyaluronate gel (HG) stapedotomy is safe and effective, reducing early dizziness and nystagmus. Hearing results were similar to standard stapedotomy, suggesting quicker recovery for otosclerosis surgery patients.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Audiology

Background:

  • Stapedotomy is a common surgical procedure for otosclerosis.
  • Postoperative dizziness and nystagmus can occur after stapedotomy.
  • Sodium hyaluronate gel (HG) is a biomaterial with potential applications in otologic surgery.

Purpose of the Study:

  • To evaluate the impact of applying sodium hyaluronate gel (HG) to the oval window niche during stapedotomy.
  • To compare hearing outcomes and the incidence of postoperative dizziness and nystagmus between stapedotomy with and without HG.

Main Methods:

  • A case-control study was conducted comparing 27 stapedotomies with HG and 32 stapedotomies without HG.
  • Preoperative and postoperative audiometric data were collected.

  • Postoperative dizziness (vertigo or dysequilibrium) and nystagmus were assessed as outcome measures.

    • Main Results:

    • No statistically significant difference in postoperative hearing results was observed between the two groups.
    • No cases of sensorineural hearing loss exceeding 10 dB occurred postoperatively.
    • The HG group showed a statistically significant reduction in early postoperative dizziness (P=0.043) and nystagmus (P=0.024).

    Conclusions:

    • Stapedotomy with HG application is a safe and effective technique.
    • HG stapedotomy leads to reduced early postoperative dizziness and nystagmus compared to standard stapedotomy.
    • HG may facilitate quicker recovery in outpatient otosclerosis surgery by preventing blood or perilymph leakage.
