For decades, Caenorhabditis elegans roundworms have been used to study the sense of touch, and this work has been facilitated by a simple behavioral assay for touch sensation. To perform this classical assay, an experimenter uses an eyebrow hair to gently touch a moving worm and observes whether or not the worm reverses direction. We used two experimental approaches to determine the manner and moment of contact between the eyebrow hair tool and freely moving animals and the forces delivered by the classical assay...

Unilateral peripheral facial paralysis (UPFP) is a form of facial nerve paralysis and clinically classified according to conditions of facial symmetry. Prompt and precise assessment is crucial to neural rehabilitation of UPFP. The prevalent House-Brackmann (HB) grading system relies on subjective judgments with significant inter-observation variation. Therefore to explore an objective method for UPFP assessment, clinical image sequences are captured using a web camera setup while 5 healthy and 27 UPFP subjects performing a group of pre-defined actions, including keeping expressionless, raising brows, closing eyes, bulging cheek and showing teeth in turn...

Typical absence seizures are observed in various epilepsy syndromes, however, few series have focused on early-onset absence epilepsy (EOAE). We aimed to evaluate the occurrence of this seizure type in children under 4 years of age in order to evaluate their electroclinical characteristics and outcome. We retrospectively studied (2006-2014) the electroclinical features of children with normal development and typical absence seizures starting before the age of 4 (with available pre-treatment video-EEG). Nine patients were included...

PURPOSE OF REVIEW: To review the recent literature in regards to complications after reconstruction of Mohs defects, outline common pitfalls and to discuss the literature on avoiding complications as outlined per aesthetic subunit. RECENT FINDINGS: Complications in facial Mohs reconstruction commonly consist of infection, wound necrosis and dehiscence, hematoma and suboptimal scarring. However, site-specific complications such as hairline or eyebrow distortion, eyelid retraction or ectropion, nasal contour abnormality, alar retraction, nasal valve compromise, significant facial asymmetry or even oral incompetence must also be considered...

OBJECTIVE: Ventriculostomy from Paine's point is an effective technique to obtain a slack brain for aneurysm surgery. This study aimed to use Paine's point for other neurosurgical procedures (except for those that require pterional approach) by delineation of surface landmarks for identification of Paine's point on the cranium and scalp. METHODS: Based on the anatomical knowledge and examination of 3D CT images of skull, we determined novel surface landmarks to identify Paine's point on cranium and scalp...

Polarizable calcium oxalate (CaOx) crystals have been well documented in breast biopsies, generally associated with benign apocrine metaplasia. In contrast, polarizable crystals are only rarely reported in skin adnexal neoplasms. We report three different cases of sweat gland tumors with polarizable crystals morphologically suggestive of CaOx: 1 apocrine hidrocystoma and 2 tubular apocrine adenomas. The histologic features were examined in 3 cases. Clinical presentation summary included 2 males and 1 female, ages 53 to 74, with lesions located on the left cheek, inferior vertex scalp and the left eyebrow...

BACKGROUND: Tricho-rhino-phalangeal syndrome (TRPS) is an autosomal dominant disorder characterized by craniofacial and skeletal malformations including short stature, thin scalp hair, sparse lateral eyebrows, pear-shaped nose and cone shaped epiphyses. This condition is caused by haploinsufficiency of the TRPS1 gene. Previous genotype-phenotype studies have correlated exon 6 missense mutations with TRPS type III, a severe form of type I with pronounced, facial characteristics, short stature and brachydactyly and differing from type II by the absence of exostoses and mental retardation...

Of all the craniofacial abnormalities, facial clefts are the most disfiguring. Facial clefts are classified according to the affected anatomical area as described by Tessier. Through this classification, the location and extent of the cleft can be designated numerically.A 2-month-old male infant was referred to authors' craniofacial unit, from a hospital in a rural province of South Africa, with a problem of a supranasal encephalocoele. Bilateral raised eyebrows were noted as was a right-sided upper lid central third coloboma...

Isolated 7p22.3p22.2 deletions are rarely described with only two reports in the literature. Most other reported cases either involve a much larger region of the 7p arm or have an additional copy number variation. Here, we report five patients with overlapping microdeletions at 7p22.3p22.2. The patients presented with variable developmental delays, exhibiting relative weaknesses in expressive language skills and relative strengths in gross, and fine motor skills. The most consistent facial features seen in these patients included a broad nasal root, a prominent forehead a prominent glabella and arched eyebrows...

BACKGROUND: There is little information about how hair diameter differences within the safe donor area. Thicker or thinner hair may be needed depending on the recipient area, hairline design, and surgical purpose. METHODS: Thirty-eight non-alopecic subjects (19 males and 19 females) were evaluated. The safe donor area was defined as the area contained within 28 cm from the horizontal plane of the upper border of the hair rim to the vertical line of the bilateral external acoustic meatus...

BACKGROUND: As opposed to upper and lower extremity amputations representing a considerable volume of admissions, the prowess of microsurgeons is seldom solicited in complex cases of head and neck replantation. Our aim was to determine the rate of successful replantation of craniofacial parts in a systematic review of the literature. METHODS: We performed a systematic review of English literature using PubMed/MEDLINE for every replantation of a head and neck parts...

BACKGROUND: Frontal fibrosing alopecia (FFA) is a chronic scarring alopecia with an unpredictable evolution. There are no current classifications of this disease that may predict its prognosis. OBJECTIVE: To analyze the differences in clinical presentation and evolution of FFA patients and to create a clinical and prognostic classification METHODS: We conducted a retrospective analytical study of FFA patients. Clinical characteristics of frontal hairline recession were used as the sorting variable between patterns of presentation...

Rhinoplasty results are evaluated both objectively and subjectively following any procedure by plastic surgeons and nonplastic surgeons at meetings, in publications, and online. We aim to evaluate whether subjective aesthetics of non-nasal features, such as the eyes and lips, would influence the overall evaluation of rhinoplasty results. We matched pairs of photographs of patients who had undergone aesthetic rhinoplasty by sex, age, and skin tone. We transferred the eyes/eyebrows and lips from the photographs of the donor patient onto the photographs of the original patient to create composite photographs...

INTRODUCTION: In selected cases, microsurgical clipping remains a valuable treatment alternative to endovascular occlusion of anterior communicating artery (AComA) aneurysms. Their clipping is challenging and carries a risk of postsurgical cognitive impairment. We evaluate the microsurgical anatomy of a new, minimally invasive combined interhemispheric-subfrontal approach to the AComA complex via a medial supraorbital craniotomy. METHODS: In this descriptive anatomic study, four alcohol-embedded, silicon-injected human cadaver heads were used...

PURPOSE: Loss of volume in the sub-brow fat pad with associated descent of the eyebrow is a common anatomical finding resulting in both functional and aesthetic consequences. A variety of techniques have been described to address brow position at the time of blepharoplasty. To our knowledge, none of these techniques treat the sub-brow fat pad as an isolated unit. Doing so enables the surgeon to stabilize and volumize the brow without resultant tension on the blepharoplasty wound. The authors describe a technique for addressing volume loss in the eyebrow with associated brow descent that treats the sub-brow fat pad as an isolated unit...
