ABSTRACT
Objective:
To evaluate the preliminary value of the cross-sectional area and morphological changes of the external ear canal opening after the two-flap auriculoplasty through the I shaped posterior incision.Methods:
One hundred and thirty-seven patientsï¼a total of 155 earsï¼ who received open radical mastoidectomy in the department of otolaryngology in the First Affiliated Hospital of Kunming Medical University were treated with I shaped incision and two-flap auriculoplasty. Vertical diameterï¼D1ï¼ and horizontal diameterï¼D2ï¼ of the external ear canal were measured at the completion of surgery, 1 month and 6 months post-operation, respectively. The cross-sectional areaï¼S=1/4πD1×D2ï¼ of the external ear canal was calculated according to the two diameters. The dry ear time and intraoperative lumen epithelialization time were observed after operation. At 6 months after operation, the morphology of the external ear canal opening was analyzed.Results:
The postoperative dry ear duration was 18-61 daysï¼27.32±7.52ï¼ days. The time to complete epithelialization of the operative cavity was 24-70 daysï¼32.18±10.36ï¼ days. Six months after the operation, the morphological classification of 155 outer ear meatal openings was as follows 117 earsï¼ 75.48%ï¼ were roundï¼the difference between vertical diameter and horizontal diameter was within 2 mmï¼; Ovalï¼oval appearance, difference between vertical diameter and horizontal diameter greater than 2 mmï¼ 35 earsï¼22.58%ï¼, triangle 3 earsï¼1.94%ï¼; Irregular ear canal orifice was not observed in all cases. During the operation, and at 1 month and 6 months after the operation, the cross-sectional area of the external ear canal wasï¼2.51±0.48ï¼ cm², ï¼2.45±0.35ï¼ cm², ï¼2.41±0.43ï¼ cm², respectively. And no significant differences were observed. ï¼P>0.05ï¼.Conclusion:
The I shaped posterior auricular incision and two-flap auricular lumenoplasty is not compex and easy to perform. The morphology of the external ear opening is regular after the operation, which can effectively match the ventilation of the operative cavity.Palabras clave
