According to an algorithm proposed by the authors (p. 1939), it is recommended that patients with advanced otosclerosis receive a cochlear implant (as opposed to stapedotomy) if:<p></p><ul> <li>maximum speech discrimination is below 30%;</li> <li>maximum speech discrimination is between 30% and 70% and CT scan Rotteveel grade is 2C or 3; or</li> <li>maximum speech discrimination is between 30% and 50%, CT scan Rotteveel grade is not 2C or 3, and air-bone gap is no greater than 30 dB.</li></ul>
Patients should receive a hearing aid and follow-up if:<div><ul> <li>maximum speech discrimination is between 50% and 70%;</li> <li>CT scan Rotteveel grade is not 2C or 3; and</li> <li>air-bone gap is no greater than 30 dB.</li></ul></div>
