The human ear is a defining feature of the face. Its subtle structures convey signs age and sex that are unmistakable yet not easily defined. With analysis normative cross-sectional data, this study explored anatomic aesthetic differences in between men women, as well changes morphology with age. A total 123 volunteers were randomly selected for study. cohort consisted 89 women ages 19 to 65 years (median age, 42 years) 34 18 61 35 years). average height across entire both left right ears...
A study was undertaken to evaluate the safety of magnetic resonance imaging (MRI) metallic implants used in cranio-orbital reconstruction (stainless steel wire and titanium Vitallium plates) also compare degree artifact created on computed tomographic (CT) scanning MRI by each material. Samples material were tested for deflection (movement) a 1.5-T field temperature change under conditions simulating clinical scan. None materials exhibited any deflection, none significant compared with...
Summary: Many techniques have been described for lower eyelid surgery, and the evolution of these procedures has seen significant advances, from simple skin excision to fat preservation repositioning. Lower lid blepharoplasty can address lid-cheek junction tear-trough deformities, which cause aesthetic concerns patients, giving appearance fatigue sadness. However, there is potential serious functional complications, including dry eyes, scleral show, ectropion. In addition, many surgeons...
Submandibular gland resection for aesthetic reasons has been hotly debated. Detractors maintain that the procedure is dangerous because it puts too many important structures at risk, notably motor nerves. The present study was undertaken to elucidate neurovascular and soft-tissue anatomy of digastric triangle via cadaver dissections so a surgical approach achieve safe submandibular could be performed. Fifteen triangles were performed in fixed fresh specimens. dissection focus understand...
A persistent problem with nasal bone osteotomies is inadequate reduction of the width dorsum. In addition, an algorithm as to which osteotomy use has not been fully explored.Nine cadavers received a medial oblique (15 30 degrees off midline) following humpectomy in six. On one side, was performed on side apex open roof. contralateral it lateral apex. The osteotome then pried posteriorly. resultant hemidorsal widths were compared. Clinically, 53 patients classified into following: type I,...
Precise lateral nasal osteotomies combined with digital greenstick infracture can be a key feature in determining the success of rhinoplasty procedure. This procedure may difficult to perform consistently because surgeon relies on tactile cues transmitted through intact soft tissue. In 17 cadavers known demographics, bone fracture patterns after osteotomy and were studied compared measured pyramid thicknesses. One side each nose served measure wall thicknesses by drilling holes grid pattern...

The traditional surgical management of complex craniofacial injuries is performed in three stages: immediate craniotomy, orbitofacial repair 7 to 10 days, and cranioplasty delayed 6 12 months because the perceived risks infection prolonged anesthesia head-injured patient. Cosmetic considerations have always played a secondary role; however, there are reports that suggest bone fragments grafts can be safely placed even contaminated wounds. In addition, advances neuroanesthetic technique allow...
Forehead rejuvenation procedures can lead to excessive elevation of the medial brow, resulting in "surprised look." Differential treatment and lateral brow allows more precise positioning. The purpose this study was determine whether retaining structures exist forehead that would permit differential elevation.Anatomical dissections were performed foreheads 12 cadavers. Multiplanar at subperiosteal, subgaleal, subcutaneous levels on eight hemiforeheads. Clinical correlation for these findings...
Background: The brow and forehead are essential elements of the facial aesthetic architecture. Although frequently overlooked in youth, signs aging often most noticeable upper third face. Ptosis loss contour brows, along with temporal volume loss, sagging periorbital tissue, rhytides forehead, common presenting complaints for surgery. use nonsurgical procedures (e.g., neuromodulators) has become very practice, knowledge surgical anatomy interventions rejuvenation critical a plastic surgeon....
We describe a minimally invasive endovascular approach to treat an arteriovenous fistula of the scalp. performed direct puncture lesion through patient's scalp for liquid embolic agent injection along with external compression superficial temporal artery perform "manual pressure-cooker technique." The combination these techniques resulted in excellent clinical and radiographic outcome.
Bone-graft reconstruction of large orbital defects has been difficult because a lack marginal support the grafts and unpredictable resorption. A titanium mesh plate developed to provide this for bone grafts. However, problem bone-graft resorption remains. To determine if any effect on graft resorption, study was designed quantitate dimensions composition autografts (1) with without (2) in anterior posterior orbit. Bilateral full-thickness floor were surgically created five monkeys, fixed...
Abstract Adequate exposure of intraoral tumors occupying the posterior oral cavity, base tongue, tonsil, and superior hypopharynx for wide‐field primary surgical resection is critical to precise tumor ablation. The resulting from a mandibular osteotomy has greatly assisted ablation these areas. This procedure also been beneficial in providing anterior skull base, pterygomaxillary, infratemporal space, clivus, nasopharynx. In evaluating various sites methods fixation, we reviewed 26 patients...
Previous maxillofacial trauma research has dealt primarily with facial bone fractures in the general population. Very few studies have specifically addressed elderly. We compared 45 elderly (65 years of age or older) and 201 younger adult (16 to 64 age) patients admitted our hospital fractures. The percentage nasal was much greater population, while mandibular were more common group. Motor vehicle accidents accounted for over half injuries both groups, falls prevalent Management patient may...
Nerve injuries are possible during facial rejuvenation surgery. The great auricular nerve has been studied; however, little is known about the lesser occipital and its relevance in To understand importance of a face lift procedure, specific anatomy was studied laboratory 19 hemifaces, with additional observations operating room. course nerve, branches, relationship surrounding structures were evaluated recorded. also dissected to compare two territories. In majority dissections, supplied...
Background: Premature aging of the perioral soft tissues face is a common complaint patients seeking facial rejuvenation, although its cause unclear. The subcutaneous fat compartments may be differentially affected by aging. Despite efforts to study and rejuvenate periorbit, midface, jowls, effects on mound have been less studied. Methods: To better understand age-associated changes in area, cadaver dissection was performed. Eight fresh fixed cadavers with evidence fullness were used...
Nasal reconstruction may best be carried out with bone grafting in certain cases of loss structural support. In order to optimize both the aesthetic and functional results bone-graft nasal reconstruction, we studied shape thickness normal human bone. Sixty Caucasian skull bones were measured by width throughout their length at three planes depth. Seventeen cadaver examined determine its sagittal planes. The showed that was widest nasofrontal suture (14 mm), narrowest angle (10 then widened...
The use of medial osteotomies as an adjunct in rhinoplasty represents ongoing challenge to the surgeon. Despite previous descriptions, it remains difficult obtain a consistent, aesthetically pleasing result. Nasal skin is thin and unforgiving region osteotomy, thus irregularities may be created. Also, bony collapse possible with overmobilization osteotomy segment. present study was undertaken understand nasal bone thickness fracture tendencies provide consistent results when performing...
The operative management of the bulbous nasal tip is a challenging and unsolved problem. Surgical alteration often leads to disappointing postoperative results. options for soft tissue range from defatting scoring dermis no soft-tissue removal at all. goal this study was determine anatomically histologically exact nature tissue. Forty-two specimens were obtained 23 patients undergoing surgery. These stained with standard hematoxylin eosin stain combined Mallory trichrome elastic examined...
