It is common in practicing orthognathic surgery to evaluate faces with retruded or protruded chins (dysgnathic faces) using photographs. Because motion may alter how the face is perceived, we investigated the perception of faces presented via photographs and videos. Two hundred naïve raters (lay persons, without maxillo facial surgery background) evaluated 12 subjects with varying chin anatomy [so-called skeletal Class I (normal chin), Class II (retruded chin), and Class III (protruded chin)]. Starting from eight traits, with Factor analysis we found a two-Factor solution, i...

INTRODUCTION: Various aspects of the round window anatomy and anatomy of posterior tympanum have relevant implications for designing cochlear implant electrodes and visualizing the round window through facial recess. Preoperative information about possible anatomical variations of the round window and its relationships to the adjacent neurovascular structures can help reduce complications in cochlear implant surgery. OBJECTIVE: The present study was undertaken to assess the common variations in round window anatomy and the relationships to structures of the tympanum that may be relevant for cochlear implant surgery...

The lips are an essential component of the symmetry and aesthetics of the face. Cosmetic surgery to modify the lips has recently gained in popularity, but the results are in some cases disasterous. In this review, we describe the features of the ideal lips for an individual's face. The features of the ideal lips with respect to facial anatomy, important anatomical landmarks of the face, the facial proportions of the lips and ethnic and sexual differences are described. The projection and relative sizes of the upper and lower lips are as significant to lip aesthetics as the proportion of the lips to the rest of the facial structure...

BACKGROUND: The superficial (subcutaneous) facial fat compartments contribute to the signs of facial aging, but a comprehensive anatomic description of their location and their functional behavior during the application of soft tissue fillers still remains elusive. METHODS: We investigated 30 fresh frozen cephalic specimens from 13 male and 17 female Caucasian body donors (age: 78.3 ± 14.2 years, body mass index: 23.1 ± 5.3 kg/m). Upright positioned contrast enhanced CT scans and additional MR imaging was performed...

Cutaneous insertion of the facial mimic muscles concerns, at different levels, the superficial fascia of that region. A superficial musculoaponeurotic system is described at face level that facilitates skin insertion of the facial expression muscles through the superficial fascia that acquires particular functional aspects in each region of the face. The existence of a musculofascial system is seen controversial among anatomists, which is why the purpose of this study is to establish its existence at the oral region...

Congenital muscle diseases, such as myopathies or dystrophies, occur relatively frequently, with estimated incidences of up to 4.7 per 100 000 newborns. To diagnose congenital diseases in the early stages of pregnancy, and to interpret the results of increasingly advanced in utero imaging techniques, a profound knowledge of normal human morphological development of the locomotor system and the nervous system is necessary. Muscular development, however, is an often neglected topic or is only described in a general way in embryology textbooks and papers...

Background: A detailed understanding of facial anatomy, specifically the vascular framework, is crucial for delivering safe nonsurgical aesthetic procedures. To date, there is no core document based on consensus for the teaching of facial anatomy to aesthetic physicians exists. The aim of this study was to ascertain the most critical anatomical structures for avoiding disastrous complications during nonsurgical aesthetic procedures. Methods: After a detailed literature review, Delphi questionnaire was developed listing 154 anatomical structures of the face and neck for consensus review...

Forensic facial comparison (FFC) is a scientific technique used to link suspects to a crime scene based on the analysis of photos or video recordings from that scene. While basic guidelines on practice and training are provided by the Facial Identification Scientific Working Group, details of how these are applied across the world are scarce. FFC is frequently used in South Africa, with more than 700 comparisons conducted in the last two years alone. In this paper the standards of practice are outlined, with new proposed levels of agreement/conclusions...

The human face is a complex anatomic structure with an equally complex embryologic development. Derangement of the developmental process can result in various structural anomalies, which range from a mainly cosmetic deformity, such as cleft lip, to potentially life-threatening conditions such as arhinia. These anomalies (a) can occur as isolated anomalies; (b) can be associated with intracranial, spinal, or dental anomalies; or (c) can be a part of various syndromes, thus serving as diagnostic clues in such cases...

OBJECTIVES: During the physiological ageing process atrophy of the alveolar bone appears in vertical direction. This bone resorption causes pushing the limits of the maxillary sinus at the expense of a degraded bone. The sinus volume increases due to the facial development in children and adolescents or during the ageing process due to the loss of teeth and bone mass. The main aim of this study is to determine the sinus shape and sinus floor morphology related to age. MATERIALS AND METHODS: Human adult male and female cadaveric heads (aged 37 to 83 years) with different dental status were used...

The lower eyelid, which has a unique anatomy and esthetic importance, is a common site of basal cell carcinoma. The reconstruction of the defect after the wide excision of the tumour is a special concern of many plastic surgeons. How to achieve the most satisfying effect through minimal invasive is important for patients. We successfully applied the lateral orbital propeller flap for one-stage reconstruction of a large lower eyelid defect after tumour resection. We consider that this flap can achieve better tissue mobilisation as it provides effective coverage of soft tissue defects and thus is especially useful for repairing facial defects...

OBJECTIVE: Concha bullosa is generally regarded as pneumatisation of the middle turbinate in the nose. However, pneumatisation may also be seen in the superior and inferior turbinate. Computed tomography (CT) of paranasal sinuses is extremely helpful for the examination of this inaccessible area. Coronal CT sections of paranasal sinuses are particularly useful for surgical anatomy, as these images show nearly the same regions as the endoscopic examinations. The aim of this retrospective study was to evaluate the presence, incidence and unilaterality-bilaterality of superior turbinate pneumatisation and concomitant nasal pathologies...

The oral and maxillofacial region has a complex regional anatomy including hard and soft tissues. Trauma in this region may affect the airway, cause potentially life threatening bleeding and head injuries. The senses of olfaction, sight and hearing can also be disrupted as well as a profound psychological impact following disfigurement. This oral and maxillofacial trauma update provides information on demographics, incidence, pathophysiology, diagnosis, fracture patterns and management of facial trauma. It also discusses the role of new advancements in the management of facial trauma...

Children have differences in their physiology, anatomy and they are continuing to grow and develop. The management of pathology, trauma, deformity and upper airway obstruction in the young growing patient has to take into account these factors in the treatment planning for these conditions. It is important for Oral & Maxillofacial Surgeons to understand the potential impact of disease or injury on the developing facial skeleton and dentition. This chapter will provide an overview of the some of the major components of paediatric maxillofacial surgery and their management...

INTRODUCTION: Combined mid-face and nasal apparatus trauma injuries pose a significant challenge to airway patency (AW), in the immediate postoperative setting following fracture reduction. As such, the authors describe a modified technique with the goal of maintaining a patent nasal AW, while at the same time, minimizing nasopharyngeal bleeding and nasal AW edema-which can complicate patients requiring intermaxillary fixation (IMF) in the setting of pan-facial trauma. METHODS: A modified technique was devised to assist the reconstruction surgeon in avoiding the risks associated with tracheostomy placement...

BACKGROUND AND IMPORTANCE: Persistent trigeminal artery (PTA) is a rare but important anatomic variant that contributes to trigeminal neuralgia (TN). Microvascular decompression (MVD) of the responsible vessel(s) away from the trigeminal nerve provides the most complete and durable relief from TN. The role and technique of MVD for TN associated with a PTA has not been fully defined in the literature. Furthermore, assessment of PTA anatomy intraoperatively with a microscope is challenging...

Hearing research has long been facilitated by rodent models, although in some diseases, human symptoms cannot be recapitulated. The common marmoset (Callithrix jacchus) is a small, easy-to-handle New World monkey which has a similar anatomy of the temporal bone, including the middle ear ossicular chains and inner ear to humans, than in comparison with that of rodents. Here, we report a reproducible, safe, and rational surgical approach to the cochlear round window niche for the drug delivery to the inner ear of the common marmoset...

Background: The eyebrow region presents challenges for filling: the skin is thick, the three-dimensional anatomy is complex and there is a predisposition towards fat atrophy and skeletonization with aging. Hyaluronic acid gel fillers are well known for their use in the periorbital region. We report our long-term experience with eyebrow filling over a period of five years. Methods: Twenty cases of periorbital eyebrow filling with hyaluronic acid gel fillers were followed up over a period of five years. The eyebrow filling was customized based on the patient's anatomical features in a three-dimensional plane...
