Abstract:
:The authors have previously described a classification system for earlobe ptosis and have established a criterion for earlobe pseudoptosis. Earlobe heights were characterized based on anatomic landmarks, including the intertragal notch, the otobasion inferius (the most caudal anterior attachment of the earlobe to the cheek skin), and the subaurale (the most caudal extension of the earlobe free margin). The classification system was derived from earlobe height preferences as determined by a survey of North American Caucasians, and it identified the ideal free caudal lobule height range to measure 1 to 5 mm from otobasion inferius to subaurale (grade I ptosis). Also, earlobe pseudoptosis was defined by the attached cephalic lobule height measuring an intertragal notch to otobasion inferius distance greater than 15 mm. In this study, the preoperative earlobe height measurements of 44 patients seeking facial rejuvenation were evaluated. The average attached cephalic segment (intertragal notch to otobasion inferius distance) of patient earlobes measured 11.10 +/- 0.46 mm, and the average free caudal segment (otobasion inferius to subaurale distance) of patient earlobes measured 7.15 +/- 0.49 mm. Assessment of patient groups based on single-decade age differences demonstrated an increase in the free caudal segment (otobasion inferius to subaurale distance) with increasing age (p = 0.003). Assessment of patient groups based on single-decade age differences demonstrated no increase in the attached cephalic segment (intertragal notch to otobasion inferius distances) with increasing age (p = 0.281). When evaluating for the ideal otobasion inferius to subaurale distance, only 22.2 percent of earlobes demonstrated an ideal free caudal earlobe height (grade I ptosis). Moreover, pseudoptosis was detected in 12.3 percent of earlobes. Finally, a majority of earlobes demonstrated intrapatient variability, with only 16.2 percent of patients demonstrating identical attached cephalic segment (intertragal notch to otobasion inferius distances) and 37.8 percent demonstrating identical free caudal segment (otobasion inferius to subaurale distances) when compared with their contralateral ear. Plastic surgeons should be aware that a significant number of patients (77.8 percent of earlobes) may not possess an ideal free caudal segment and that 12.3 percent of earlobes may present with pseudoptosis. Therefore, earlobe height assessment should be an essential aspect of evaluation in patients desiring facial rejuvenation surgery. Evaluation of both ears should be performed independently due to intrapatient earlobe height variations. Finally, patients should be counseled with regard to the ideal earlobe parameters and aging patterns (stable attached cephalic segment versus increasing free caudal segment). With the natural progression of both facial rhytides and caudal segment earlobe ptosis (increasing free lobule segment) with increasing age, independent and accurate assessment of earlobe height is indicated so that the aging ear may be addressed concurrently with the aging face.
