The\u00a0parameters were similar at the seventh and eighth months of gestation; therefore, there was no variation from the seventh month. Linear function\u00a0was calculated as y = 1.328 + 0.281 x weeks (P &lt; .001) for the TRH, y = 1.284 + 0.258 x weeks (P &lt; .001) for the TRW, y = 3.367 + 0.876 x weeks\u00a0(P &lt; .001) for the TRP, and y = \u22120.603 + 0.188 x weeks (P &lt; .001) for the TNW.\n\nCONCLUSION: The parameters (TRH, TRW, TRP, and TNW) did not alter from the seventh month in utero. The linear functions (which represent\u00a0the growth pattern of the parameters) of the tympanic ring may be useful for ear professionals to guess the annulus diameters, and to diagnose\u00a0growth retardation and probable congenital anomalies in utero during sonographic imaging.\n\nCite this article as: Beger O, Vayiso\u011flu Y, Bobu\u015f \u00d6rs A, et al.
