A novel method for the determination of exostosis severity in the external auditory canal.

Magnification error may be considered a potential limitation in our recommended analysis; however, the procedure assesses relative areas (external auditory canal and exostosis) as opposed to quantifying absolute 3D measurements of the exostosis. RESULTS AND ANALYSIS The analysis initiated with the assumption that rounding to a 10th of a millimetre SP 2 sp was sufficient for the purpose of estimating exostosis percentage ((exostosis area mm SP 2 sp /auditory canal area mm SP 2 sp )*100).
