Which otoplasty (and conchal reduction) method should I choose? All suggested Mustarde sutures to pin the ear back. Pros/Cons?

The technique I recommend is partial conchal bone resection.  This technique is easy to perform and produces symmetrical, predictable permanent results.Best Wishes,Gary Horndeski, M.D.

All the techniques you mention are acceptable and work well.  I often combine these techniques when needed to get the desired results.  It is true that many surgeons differ in their approach and experience in otoplasty since it is not done as frequently as some of the other aesthetic procedures.

A full set of pictures of the ears are required to make a determination about the best technique to perform an otoplasty.  When patients have a lack of the antihelical fold, sutures are placed in the back of the ear to re-create that fold.  That enables the top of the ear to be pinned back.  When patients have a prominent conchal bowl, additional sutures are used to hold that area of the ear back to the mastoid fascia on the head.  For more information and many before and after  examples, please see the link below

There are a number of ways to perform otoplasty. I would look less at the method of achieving the result than the result itself. You have to be comfortable with the confidence of your surgeon and the results he/she is able to achieve on previous patients.

Good results are possible with various techniques. An experienced surgeon will usually get  the best results using the technique/s with which they are most familiar or use regularly. I advise you check with your surgeon about their experience with otoplasty and see a suitably qualified and experienced plastic surgeon. Ask them about their revision rates. Here is an explanation of techniques for surgical otoplasty that I use or have used.Mustard suturesThese are used to make or  increase the folding of the anti-helical fold. A flat or under folded anti-helical fold is one of the most common reasons for prominent ears. This is often combined with something to weaken the cartilage to resist it springing back. This could be by thinning, making cuts in it or my preference is to bipolar diathermy (electrocauterise) the back of the cartilage which tends to make it fold and then stay folded (this can be called a thermo-chondro-plasty which I learn't from the late Don McNeil at Odstock, Salisbury, UK many years ago).Conchal cartilage excisionAn alternative technique or complimentary approach addresses the problem of an enlarged conchal cartilage. This may be the cause of prominent ears on its own or in combination with a flat anti-helical fold. If the cause is only a large conchal cartilage then removing a crescent of cartilage from the conchal bowl can be an excellent technique on its own for correcting a prominent ear.Anterior scorring technique (Chong Chet method)This is also an excellent method which I used extensively in the past. I never had a serious problem with it but I consider it to be a riskier method due to the potential for bleeding under the skin resulting in a hematoma which if infected can result in a very badly deformed ear. In view of this risk and in the face of alternatives (above) I elected to stop using it routinely. It is however, a technique with which I produced many happy patients in the past. It was only after speaking with an ear reconstruction specialist (David Gault, London) about his experiences with complications of this technique that  I decided there were safer ways of producing equivalent results.In practice I most often use Mustard sutures and not infrequently with a conchal excision. Least often I will just do a conchal excision.I hope my perspective does not simply add a 4th 'opinion'! but perhaps helps you to understand some of the different approaches to otoplasty.Best wishes

There are many different ways to perform an otoplasty.  All of the techniques offered by the surgeons you consulted with are certainly effective.  The truth is that there is no gold standard method for addressing the conchal cartilage during an otoplasty.  Some surgeons use techniques that resect a portion of the cartilage and others use cartilage sparing techniques.  A good result could be obtained with a number of different techniques.  I would recommend that you choose the surgeon with whom you felt the most comfortable and established a good rapport.  You will likely have a good result with any of the previously mentioned techniques so it may be more beneficial to choose the surgeon or the practice based on your comfort.  I hope this helps, good luck!!
