'Lips and Perioral Region Anatomy' (53)


Jun
2017

The perioral region is unique and important in the face, both from a functional and an aesthetic point of view. There is a strong relationship between the perioral soft tissues, such as the lips and the corners of the mouth, and the underlying dentition and the jaws. Perioral ageing phenomena, such as depressed corners of the mouth, volume loss and wrinkles, can be improved, however, to a limited extent with intraoral treatment.

Furuncular myiasis is a parasitic infection caused by the larvae of Dipteran insects after penetrating healthy skin, causing an erythematous nodule with a central pore. Additionally, the patient may feel a sensation of movement and intermittent pain. Furuncular myiasis affecting the oral and perioral region is rare, usually leading to misdiagnosis.

Although aging changes of the female perioral region and aesthetic procedures for perioral rejuvenation are described in literature, specific data for the male population are lacking. This study aims to evaluate perioral aging process in the male population to compare quality and quantity of the observed changes to the female population.
Magnetic resonance imaging (MRI) scans of 22 male subjects, were recruited into 2 age groups: young (20-35 years) and old (65-80 years) and the following parameters were measured: length of visible upper lip, thickness of upper lip at the level of vermilion border, thickness of upper lip at the level of the mid lip, and cross-section area of upper lip.

The ultrasonographic surface rendered oro-palatal (SROP) view is a 3D reconstructed view of the fetal perioral region, which combines ultrasound insonation in a trans oral, upward directed axial direction and the surface rendered mode. It allows the simultaneous visualization on a single scan of the superior lip, alveolar ridge and secondary palate. It corresponds prenatally to the submental intra oral photography of the palate of neonates.

Understanding the Perioral Anatomy.

Plast Surg Nurs 2016 Jan-Mar;36(1):12-8; quiz E1
Tracey A Hotta
Rejuvenation of the perioral region can be very challenging because of the many factors that affect the appearance of this area, such as repeated muscle movement causing radial lip lines, loss of the maxillary and mandibular bony support, and decrease and descent of the adipose tissue causing the formation of "jowls." Environmental issues must also be addressed, such as smoking, sun damage, and poor dental health. When assessing a client for perioral rejuvenation, it is critical that the provider understands the perioral anatomy so that high-risk areas may be identified and precautions are taken to prevent serious adverse events from occurring.

Throughout literature, there are different parameters defining the ideal shape of the lip and lower third of the face. This study was conducted to clarify what it is that makes lips attractive - and whether there are gender-related differences of an attractive lip and lower third of the face.
Pictures of the lip and chin region of 176 patients were photographed in a standardised way and evaluated by 250 voluntary judges through an internet presentation by means of an analogue Likert scaling system.

Various types of anterior chest flaps can be recruited in the reconstruction of faciocervical region. Most of them were created based on the internal mammary artery and the lateral thoracic artery, and the thoracoacromial artery (TAA) is usually used in pectoralis major musculocutaneous flap. An anterior chest flap with TAA perforator (TAAP) will have no sacrifice of the pectoralis major muscle, but less reports, especially expanded pedicled one, can be reviewed.

Acquired angioedema is a rare but recognized manifestation of lymphoproliferative disorders due to deficiency in C1 esterase inhibitor. Normal level of C1 esterase inhibitor proteins in association with angioedema due to lymphoproliferative disease is a rare and an uncommon finding caused by antibodies produced from the underlying disease. Antibodies cause inactivation of C1 esterase inhibitor, thus resulting in C1 esterase inhibitor dysfunction despite of normal quantity of C1 esterase inhibitor.

Lips and the perioral area are of outstanding importance in youthful appearance, attractiveness, and beauty. In contrast to younger and middle aged females, there is only scant published data on minimally invasive procedures to restore and revitalize lips and perioral soft tissue in elderly females. In this review we report the signs of aging in this particular region and the underlying anatomy.

The hidrocystomas (HCs) are cystic forms of sweat gland resulting from proliferation of the apocrine secretory coil or eccrine duct. Apocrine -HCs are cystic lesions that arise from the apocrine secretory coil, while eccrine -HCs represent retention cysts of the eccrine duct. The commonest site for such lesions is around the eye, and they may also occur on the ears, scalp, chest, shoulders, or feet.

Surgical correction of cleft lip and palate.

Front Oral Biol 2012 25;16:101-10. Epub 2012 Jun 25.
Rahul Jayaram, Christoph Huppa
Surgical cleft repair aims to restore function of the oro-nasal sphincter and oro-nasal soft tissues and re-establish the complex relationship between perioral and perinasal muscle rings without compromising subsequent mid-facial growth and development. Here we review the surgical anatomy of this region, optimal timing for surgical repair and current thinking on the use of surgical adjuncts. In addition, an overview of current surgical techniques available for the repair of cleft lip, cleft palate and velopharyngeal insufficiency is presented.

Closure of perioral surgical defects involving the oral commissures is highly challenging. We describe a 69-year-old male patient with a large basal cell carcinoma of the right perioral region, extending to the right oral commissure. This lesion was radically excised, and the resulting surgical defect was closed using a homolateral double opposing rhomboidal flap.

The perioral region is subject to a myriad of different treatments for rejuvenation, many of which are applied without a clear understanding of the underlying physiological processes of perioral aging. The results of these procedures are therefore sometimes not optimal and do not achieve a natural youthful appearance. The aim of this study was to put the results of three investigations into the perioral aging process into relation to clinical application in aesthetic medicine.

There has been minimal attention paid in the literature to the aesthetics of the perioral area, either in youth or in senescence. Aging around the lips traditionally was thought to result from a combination of thinning skin surrounding the area, ptosis, and loss of volume in the lips. The atrophy of senescence was treated by adding volume to the lips and filling the deep nasolabial creases.

Women tend to develop more and deeper wrinkles in the perioral region than men. Although much is known about the complex mechanisms involved in skin aging, previous studies have described histologic differences between men and women with respect to skin aging only incidentally and have not investigated the perioral region.
The purpose of this study was to investigate gender-specific differences in the perioral skin.

Between the two different kinds of the skin covering the body, the glabrous skin is found only on the palmo-plantar surface because of its rather simple function to protect the underlying living tissue with its remarkably thick stratum corneum (SC) from strong external force and friction. Thus, its barrier function is extremely poor. In contrast, the hair-bearing skin covers almost all over the body surface regardless of the presence of long hair or vellus hair.

Every practitioner has the obligation to offer his or her patients the latest advances in their profession. Dentistry has made a shift over the past 50 years from caries restoration and prosthetic replacement to preventative and esthetic rejuvenation. Related dental specialties have also blossomed with new procedures and an expanded scope of practice.

Although orthodontic treatment improves dentoalveolar problems, the facial profile seldom changes because the perioral muscles do not easily adapt to the new morphological circumstances. We employed proprioceptive neuromuscular facilitation (PNF), which is training with added resisted movement to motions such as lifting the upper lip, lowering the lower lip, and sticking out the tongue, to adapt the perioral muscles to the new morphological circumstances. The subjects were 40 adults with an average age of 29.

The perioral region has certain anatomic characteristics that make it unique and responsive to different types of rejuvenation treatments, including surgery, soft tissue fillers, laser, and chemical peeling. An understanding of the structural anatomy, relationships to other facial units, attractiveness, and analysis of the aging process will help the surgeon select appropriate and long-lasting treatments. This article serves as a basis for facial analysis and preoperative planning, presuming a normal dental-skeletal relationship.

The granule cell layer of the cerebellar hemispheres contains a patchy and noncontinuous map of the body surface, consisting of a complex mosaic of multiple perioral tactile representations. Previous physiological studies have shown that cerebrocerebellar mossy fibre projections, conveyed through the pontine nuclei, are mapped in registration with peripheral tactile projections to the cerebellum. In contrast to the fractured cerebellar map, the primary somatosensory cortex (SI) is somatotopically organized.

Accurate clinical assessment of the infraorbital and mental branch of the trigeminal nerve is aided by an appreciation of the variations in sensitivity that may exist along the surface of the perioral region under examination. The purpose of this investigation was to map the mediolateral spatial and frequency variations in vibrotactile detection capacity to inputs delivered to the upper lip (UL) and lower lip (LL) vermilion. Mechanical vibrotactile inputs at frequencies of 5, 10, 50, and 150 Hz were delivered to three locations on the vermilion of the UL and LL: midsagittally and laterally (left and right) at a point halfway between the midsagittal plane and the oral angle.

The dramatic rise in the number of cosmetic procedures performed during the past 5 years reflects a heightened public awareness of and interest in facial rejuvenation. Concomitant with this rise has been the addition of new injectable fillers, lasers, and minimal incision techniques to the surgeon's armamentarium. Perhaps the greatest applicability of these modalities has been the rejuvenation of the perioral region, neck, and jawline, with reduced "downtime" but visible results.

The use of flaps to reconstruct lip defects requires detailed knowledge of the local vasculature. New flaps for surgery around the mouth can be devised if the surgeon knows the distribution of the perioral arterial branches. Examination of the anatomy of perioral branches of the facial artery (FA) confirmed the consistent presence of septal and alar branches in the upper lip and a labiomental branch in the lower lip.

We sought to define the contribution of the climbing fibers (CF), one of the major inputs to Purkinje neurons, to the increase in cerebellar blood flow (BFcrb) produced by activation of the cerebellar cortex. The neurotoxin 3-acetylpyridine was used to lesion the inferior olive, the site from which the CF originate. Crus II, an area of the cerebellar cortex that receives sensory afferents from the perioral region, was activated by low-intensity stimulation of the upper lip (5-25 V and 4-16 Hz) in sham-lesioned and lesioned mice.

We recorded activity from the granule cell layer (GCL) of cerebellar folium Crus IIa as freely moving rats engaged in a variety of natural behaviors, including grooming, eating, and free tactile exploration. Multiunit responses in the 1000-4500 Hz range were found to be strongly correlated with tactile stimulation of lip and whisker (perioral) regions. These responses occurred regardless of whether the stimulus was externally or self-generated and during both active and passive touch.

Crus II is an area of the cerebellar cortex that receives trigeminal afferents from the perioral region. We investigated the mechanisms of functional hyperemia in cerebellum using activation of crus II by somatosensory stimuli as a model. In particular, we sought to determine whether stimulation of the perioral region increases cerebellar blood flow (BFcrb) in crus II and, if so, whether the response depends on activation of 2-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-kainate receptors and nitric oxide (NO) production.

From 1985 through 1989, 54 patients with wrinkles around the lips and in the chin area were treated by dermabrasion. Significant improvement, lasting longer than three years, was achieved using both types of abrading tool: the wire brush and the diamond fraise. The side effects of dermabrasion were permanent but very slight bleaching in 66% of the patients and formation of milia in less than 20%.

The variable nature of the perioral system as a force generator is due, in large part, to differences in the spatial arrangement and degree of muscle representation in this region. This fact requires careful consideration when attempting to compare select properties of force dynamics among individual subjects in health and disease. The objective of the present study was to determine the relation between an indirect measure of muscle length (interangle span) and in vivo resultant force in the perioral region of normal adult subjects.

Morphometric and retrograde tracing methods were used to determine the location and number of motoneurons innervating individual facial muscles in Macaca fascicularis. Intramuscular injections of the cholera toxin B subunit-horseradish peroxidase conjugate produced discrete labeling patterns in the ipsilateral facial motor nucleus with good definition of somata and their processes. The facial nucleus extended rostrocaudally in the pons for about 2 mm, varying in shape and cross-sectional area along this axis.

The management of difficult perioral malignancies is often facilitated by an organized, multidisciplinary approach that utilizes the skills of a Mohs micrographic surgeon as well as a head and neck surgeon. This article summarizes such an approach with attention to anatomic considerations, tumor classification, prognosis, and a practical approach to such malignancies. Finally, an approach to reconstruction is presented that emphasizes the usefulness of a Karapandzic flap in large reconstructions of this region.
