Partial vs. total footplate removal in stapedectomy: a comparative study
The Laryngoscope
|July 1, 1984
Summary
Partial footplate removal (PFR) in stapedectomy offers slightly better hearing gain, especially at higher frequencies, compared to total footplate removal (TFR). Both methods show similar results in lower frequencies and for speech understanding.
Area of Science:
- Otolaryngology
- Audiology
- Surgical Outcomes
Background:
- Stapedectomy is a surgical procedure to restore hearing in patients with otosclerosis.
- The extent of footplate removal (partial vs. total) is a key surgical decision with potential impacts on outcomes.
Purpose of the Study:
- To compare the postoperative results of partial footplate removal (PFR) versus total footplate removal (TFR) in stapedectomy.
- To evaluate hearing gain, air-bone gap closure, speech function, and complication rates between the two surgical techniques.
Main Methods:
- A retrospective comparative study involving 264 ears with PFR and 106 ears with TFR.
- Analysis of audiological data including decibel gain across frequency ranges (250-1000 Hz and 2000-8000 Hz), air-bone gap closure, and speech discrimination scores.
- Assessment of the incidence of postoperative complications and the permanency of speech discrimination.
Main Results:
- PFR demonstrated a consistently greater decibel gain in the high-frequency range (2000-8000 Hz) compared to TFR.
- Decibel gain in the lower frequency range (250-1000 Hz) was comparable between PFR and TFR.
- PFR cases showed slightly better average results for air-bone gap closure and speech outcomes.
Conclusions:
- Partial footplate removal in stapedectomy may offer superior high-frequency hearing improvement compared to total footplate removal.
- Both techniques provide comparable low-frequency hearing gain and similar speech results, with PFR showing a slight advantage.
- Further examination of the long-term stability of speech discrimination is warranted.
