OBJECTIVES: Some patients complain of apparent auricle protrusion after chronic otitis media (COM) surgery with the postauricular approach. This study investigates whether auricular protrusion could be restored to the preoperative state after COM surgery; if so, the time needed after surgery and whether the degree of auricular of protrusion differed according to the surgical procedure.

MATERIALS and METHODS: Forty-seven patients who underwent tympanoplasty and canal wall up and canal wall down mastoidectomy between July 2016 and July 2017 were prospectively studied. To examine the degree of auricular protrusion, the longest distance from the head to the helical rim and the distance from the mastoid process to the helical rim in the plane along the level of the upper margin of the tragus were measured 1 day before surgery and 1 day; 2 weeks; and 1, 2, 4, and 6 months, postoperatively.

RESULTS: The superior aspect of the auricle returned to the preoperative state within 2 months of surgery, irrespective of the surgical procedure. The middle aspect was restored to the preoperative state within 4 months of tympanoplasty or canal wall up mastoidectomy, and within 2 months of canal wall down mastoidectomy.

CONCLUSION: Postoperative auricular protrusion is a transient phenomenon.
