A key indicator here is the conchoscaphal angle if it surpasses the typical 90-degree limit due to an imperfectly folded antihelix, it can lead to enhanced ear projection. A lack of proper curvature in the antihelix can cause the helical rim to project forward, giving the ear its protruded appearance. When observed from the front, the helix extends about 2 to 5 mm beyond the antihelix. Notably, the conchal bowl is characterized by a depth of about 1.5 cm, encircled by a pronounced outer edge. For the typical adult, the ear spans a height of around 6 cm, with its width being roughly 55% of its height. Additional features encompass the antitragus, intertragal incisures, and Darwin's tubercle. Predominantly, the ear consists of elements like the helix, antihelix, concha, tragus, and lobule. Though there is a spectrum of anatomical variations in ear structure from one individual to another, some standard components delineate its basic framework.

Proficient knowledge of the ear's structure enables surgeons to reduce the risk of auricular protrusion after the postauricular approach and enables them to achieve optimal aesthetic outcomes.

Understanding the details of the auricular anatomy is pivotal for assessing auricular protrusion.

In this review, we aimed to summarize the current evidence regarding the potential implications of the postauricular approach on auricula protrusion. Misalignment or protrusion can result in both functional impairment and significant patient distress, emphasizing the need for precision and expertise in both the surgical technique and postoperative care. A well-positioned auricle not only contributes to the overall aesthetic outcome but also plays a pivotal role in auditory function and patient satisfaction. Among these, the positioning of the auricle after surgery is particularly crucial. Īs with any surgical intervention, the postoperative outcomes, both functional and aesthetic, are of significant importance. The ear's stability is maintained through a combination of skin, connective tissues, soft tissues, and the auricle's external muscles. While the auricular cartilage lies adjacent to the cranium, they are not conjoined directly. However, an underlying concern exists regarding the potential alteration of the auricular shape postsurgery due to this incision. Since its first introduction, this technique has undergone numerous modifications to enhance its efficacy and minimize complications, each iteration informed by decades of surgical experience and anatomical studies. Furthermore, since the incision is placed behind the ear, it offers an aesthetic benefit by concealing the surgical incision. This approach offers unique access to the middle ear, mastoid, and other internal structures while minimizing visible external scarring. Among these, the postauricular method is frequently employed owing to its distinct advantages. Various surgical interventions for the ear, including the transcanal, endaural, and postauricular approaches, are chosen based on the surgeon's discretion. Nonetheless, it is recommended to take all precautionary measures, including appropriate patient selection, engagement of an experienced surgeon, and meticulous postoperative dressing. These findings suggest that surgeons should continue using the postauricular approach without concerns regarding auricular protrusion. In the few reports that do note its occurrence, the protrusion appears transient, resolving over time. Nevertheless, available studies predominantly indicate no association between the postauricular approach and lasting auricular protrusion. While the exact mechanisms underlying this phenomenon remain under debate, it is worth noting that comprehensive literature on this topic is scant. Despite its advantages, concerns have emerged regarding the potential for auricular protrusion following the procedure. The postauricular approach is a widely adopted surgical technique for the ear due to its unique access to the middle ear, mastoid, and other internal structures, while adeptly concealing the surgical incision for aesthetic superiority.
