After otoplasty (ear surgery), it is normal to have some visible stitches during the initial stages of healing. However, at four months post-surgery, it is expected that the majority of the stitches would have dissolved or been removed by your surgeon. The presence of visible stitches at this stage may warrant further examination by your surgeon to ensure proper healing. Regarding the bumps on the cartilage and asymmetry of your ears, these are concerns that your surgeon should evaluate during your appointment. Post-operative swelling and tissue changes can contribute to temporary asymmetry, but if you are still experiencing significant differences between your ears, it's important to discuss this with your surgeon. During your consultation, you can express your concerns and ask your surgeon to explain the healing process, address the visibility of stitches, and provide an assessment of the overall outcome. They will be able to evaluate your situation and advise you on any necessary steps, potential revision procedures, or further treatments, if required. Remember to communicate openly with your surgeon and ask any questions you may have. It's essential to have a thorough understanding of your situation and the options available to address your concerns. I hope this helps, best of luck !
