“…Additionally, we analyzed the published data with concern to the petrified ear that was confirmed in subjects without an actual diagnosis of a traditional endocrine ailment amid their medical records/history or during current admission (according to the original references). By applying the same mentioned methods, we further identified 22 single case reports (one subject with petrified ear confirmation per paper) [ 2 , 4 , 7 , 9 , 12 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ], and one patient was reported via a case series of two that also introduced another family member with a concomitant endocrine condition [ 36 ], as well as a case series of three patients [ 44 ] (hence, a total of 23 distinct articles other than those cited at endocrine-based analysis; N = a total of 26 subjects diagnosed with petrified pinna). The timeline analysis showed one case per publication per year (in 2023, 2020, 2015, 2014, 2013, 2012, 2008, and 2005), two papers per year (one subject per paper) published in 2017 and 2009, respectively, and three papers per year (in 2019, 2016, 2011, and 2007; of note, the paper published in 2016 was a three-patient series [ 44 ]).…”
