AB -  To the Editor: With great interest we have read the article “A New Wide-Diameter Bone-Anchored Hearing Implant: Prospective 1-Year Data on Complications, Implant Stability, and Survival” by Foghsgaard and Caye-Thomasen ( 1 ). We would like to congratulate the authors on a well-written article reporting on a well-designed study. However, we would also like to address a few points concerning the study design related to resonance frequency analysis (RFA) and the implant stability quotient (ISQ). This technique is relatively new in the field of percutaneous osseointegrated titanium implants for bone conduction devices (i.e., Cochlear’s Baha system and Oticon’s Ponto system), yet swiftly gaining attention because of studies on new implants and abutments supporting this technique. However, RFA has been used in dental research for about 20 years already. Briefly, RFA depends on three main factors: first, the design of the transducer (i.e., SmartPeg); second, the stiffness of the implant fixture and its interface with the tissues and surrounding bone; and third, the total effective length above the marginal bone level ( 2 ). As RFA is increasingly used in research concerning implants for bone conduction devices, the technique should be used in a consistent manner and ISQ values
