The stapes is the third of three tiny bones in the middle ear and the one closest to the inner ear. It’s occasionally called the stirrup.

In some cases, the stapes can become stuck and cannot vibrate freely, as it is intended to do in order to transmit sound into the inner ear. A condition called Otosclerosis.

This leads to a form of hearing loss called: a conductive hearing loss. This condition can also reach the inner ear capsule, resulting in another type of hearing loss called sensorineural hearing loss.

Stapedectomy ni utaratibu ambao unakusudia kukata mfupa wa stape na laser na kuibadilisha na bandia.

Lippy et al. (2003), in their article Twenty-Year Review of Revision Stapedectomy, concluded that “more than 70% of revision stapedectomy cases for hearing improvement have had successful closure of their air-bone gap. Since the introduction of the laser 5 years ago, the success rate has increased to 80%. In those specific cases where the laser was required, the success rate increased to 91.4%” (p.560).

These percentages were confirmed by the Sunny Brook Health Sciences Center, who stated that 85% of patients will have a significant hearing improvement.

Utaratibu hufanyika katikati ya sikio kupitia njia ndogo juu ya sikio iitwayo mkato wa endaural. Eardrum imeinuliwa juu na sikio la kati limeingizwa. Ili kuchukua nafasi ya stapes, nusu ya juu ya mfupa huondolewa kwa kutumia laser. Baadaye, ufunguzi mdogo unafanywa kupitia ubao wa miguu wa miamba tena kwa kutumia laser.

SIFLASER vifaa vya upasuaji, haswa SIFLASER-1.1, SIFLASER 3.3 na SIFLASER 3.2 kuwa na anuwai ya urefu wa mawimbi ambayo hutofautiana kati ya 455 nm na 1470 nm na nguvu ya 0.5W - 60W, kulingana na utumiaji wa bidhaa na inayoweza kubadilika kulingana na mahitaji ya otologists au otolaryngologists.

Vipande vifupi vya muda mfupi vina kupenya juu juu, wakati urefu mrefu zaidi una kupenya zaidi kwenye tishu, na kuzifanya zifae sana kwa stapedectomy.
