A Case of Auricular Ossification

Abstract

Ectopic ossification refers to the process of new bone formation in sites that normally do not ossify. The auricle is composed of elastic cartilage, and hence is a pliable structure. Auricular ossification is a rare condition that might be caused by injurious processes, including frostbite, physical trauma, and inflammation as well as processes related to metabolic or endocrine disorders. Here, we report a case of unilateral auricular ossification in a 53-year-old Korean man who had previously rubbed his ear repeatedly with his hand.

Endocrine Petrified Ear: Associated Endocrine Conditions in Auricular Calcification/Ossification (A Sample-Focused Analysis)

“…Studies to address the identification of auricular calcifications/ossifications amid CT scans according to our methods [7,15]. Overall, the data coming from our sample-based analysis via isolated case reports (N = 49 subjects) showed that X-ray and/or CT confirmation was done in all cases (no differences were noted in imagery approaching the patients with an endocrine [1,6,18,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] versus non-endocrine [2,4,7,9,12,36,[40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]…”

“…Table 2. Sample-focused analysis on petrified ear in subjects apparently without any endocrine conditions (according to the original reports); the display starts with the most recent publication date [2,4,7,9,12,36,[40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]. Abbreviations: B/U = bilateral or unilateral PE; C1, C2 = case 1 or 2 (patients from case series); CT = computed tomography; F = female; M = male; PE = petrified ear; P1, P2, or P3 = patient 1, 2, or 3 (patients from case series).…”

“…The hormonal assessments were provided in the endocrine cases [1,6,18,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39], but, also, as mentioned, in non-endocrine cases (to some extent) [2,4,7,9,12,36,[40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]. Despite large variations in reporting an endocrine profile, the main evaluation included:…”

“…Further on, we analyzed the endocrine sample-based cohort [1,6,18,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] in addition to this present case and another five cases from the initial non-endocrine cohort [2,4,7,9,12,36,[40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] which we re-classified due to the co-presence of endocrine-metabolic traits that potentially may be part of a pathogenic association (yet, this remains an open issue) as following: vitamin D deficiency and chronic kidney disease that potentially bring a large of calcium and phosphorus anomalies (even transitory or responsive to m...…”

New bone formation over dehiscent semicircular canal with cartilage cap

“…The mechanism of bone formation and if the cartilage itself ossifies or provides a scaffold for new bone growth is unclear. 4,5 Many patients do not have osseous coverage (1 used in our control data set) and symptoms have resolved. Therefore, it is important to remember the absence of bone formation does not imply failure of surgery.…”
