The anatomical basis for auricular flaps used in multiple aesthetic and reconstructive procedures is currently based on a random distribution of the underlying arterial network. However, recent findings reveal a systematic pattern as opposed to the present concepts. Therefore, we designed this study to assess the arterial vascular pattern of the auricle in order to provide reliable data about the vascular map required for surgical interventions. Sixteen human auricles from eight body donors (five females/three males, 84...

Myringoplasty is one of the basic procedures in otologic surgery, and is important to achieve good hearing outcome. The temporal fascia is most widely used and considered to be a stable graft in this procedure, although 10-20% of patients develop reperforation after surgery, which is often hard to repair, even by revision surgery. We herein conducted revision myringoplasty using a cartilage graft to repair postoperative reperforation in 7 patients (8 ears) with chronic otitis media. The patients were 3 males and 4 females, aged 13-80 years with an average of 53...

INTRODUCTION: The ear is a key facial feature and yet few studies have previously assessed ear aesthetics. This study aimed to assess the anatomical components of the ear that have the greatest impact on the perception of ear aesthetics. MATERIALS AND METHODS: Three photographs of a male adult ear (close-up, lateral, posterior) were digitally manipulated such that in each, 1 anatomical element of the ear was either enlarged or reduced. A complete set of 16 photographs including a repeat of the original ear as a control were randomized and entered into an online survey that required respondents to rate the attractiveness of each ear on a scale of 1 (least attractive) to 10 (most attractive)...

I encountered an ovoid mass that blocked the opening of a patient's right ear, and initially thought that it was an accessory tragus. Unusually, the cyst had developed on the tragus of the ear and was pedunculated with a linear stalk from the tragal cartilage. To the best of my knowledge, this is the first report of a dermoid cyst that involved the tragal cartilage, and was completely excised.

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months...

BACKGROUND: Mandibular distraction osteogenesis is the process of generating new bone in a gap between 2 bone segments in response to the application of graduated tensile stress across the bone gap. These distraction forces applied to bone also create tension in the surrounding soft tissues resulting in simultaneous expansion of the functional soft tissue matrix. AIM: To investigate and evaluate the changes in facial soft tissue following mandibular distraction osteogenesis and their relationship with the changes in bone movements...

BACKGROUND: Facial paralysis has a profound impact on the brow, and currently static procedures are the mainstay of treatment. The deep temporal branches of the trigeminal nerve, given their proximity to the brow, may serve as possible donor nerves for both potential innervation of a free muscle transfer in patients with prolonged facial palsy or nerve transfers in acute or subacute palsy. As such, the authors present the detailed surgical anatomy of the deep temporal nerve, assessing feasibility for both functional muscle and nerve transfers, including a proposed surgical technique...

Chloridoideae (chloridoid grasses) are a subfamily of ca. 1700 species with high diversity in arid habitats. Until now, their evolutionary relationships have primarily been studied with DNA sequences from the chloroplast, a maternally inherited organelle. Next-generation sequencing is able to efficiently recover large numbers of nuclear loci that can then be used to estimate the species phylogeny based upon bi-parentally inherited data. We sought to test our chloroplast-based hypotheses of relationships among chloridoid species with 122 nuclear loci generated through targeted-enrichment next-generation sequencing, sometimes referred to as hyb-seq...

Currently, autologous cartilage provides the gold standard for auricular reconstruction. However, synthetic biomaterials offer a number of advantages for ear reconstruction including decreased donor site morbidity and earlier surgery. Critical to implant success is the material's mechanical properties as this affects biocompatibility and extrusion. The aim of this study was to determine the biomechanical properties of human auricular cartilage. Auricular cartilage from fifteen cadavers was indented with displacement of 1 mm/s and load of 300 g to obtain a Young's modulus in compression...

Certain malformations may occur during the embryonic development of the ear. Accessory auricle has a wide range from a small elevation of skin to a large size to resemble an additional auricle, where the latter is called polyotia. This condition is defined as an accessory auricle that is large enough to closely resemble an additional pinna rather than a skin remnant and cartilage. Polyotia, also known as mirror ear or accessory ear, is a type of ear anomaly in the tragus area, but this term refers to substantial anomalies which resemble an accessory ear, unlike a pre-auricular tag...
