Study on the ideal sagittal position of the lower third of the face in high-angle patients with different forehead forms / 口腔疾病防治

Objective@#To explore the ideal sagittal position of the lower third of the face in high-angle patients with different forehead forms and to provide a reference for clinical treatment. @*Methods@#Informed consent and portrait authorization were obtained from all patients, and the study passed the ethical review of the unit. We categorized forehead forms into four types: straight, rounded, type I angular (angled at the middle third of the forehead) and type II angular (angled at the upper third of the forehead). Profiles of high-angle patients with different forehead forms were collected. The initial position was when the facial axis point (FA point) was positioned at the goal anterior-limit line (GALL). After being silhouetted, the lower third of the face was moved forward and backward by 1 mm, 2 mm, 3 mm, and 4 mm each, plus the initial silhouetted picture, to obtain 9 images for each patient. A survey was created with these lateral profile silhouettes, and the silhouette images were ranked by 30 orthodontists and 30 laypersons. @*Results@# There were significant differences in profile scores at different movement distances of the lower third of the face among high-angle patients with different forehead shapes (P<0.05). Overall, high-angle patients with straight or type II angular foreheads had higher scores when the lower third of the face did not move. For high-angle patients with a rounded forehead, orthodontists and laypersons gave the highest scores when the lower third of the face was moved backward by 2 mm and 4 mm, respectively. For high-angle patients with a type I angular forehead, orthodontists thought the scores of backward movement of 4 mm were the highest, and laypersons thought the scores of backward movement of 3 mm were the highest. No significant difference was found in scores between orthodontists and laypersons (P>0.05). @*Conclusion @#The forehead forms and the sagittal position of the lower third of the face will affect the face’s profile aesthetics. Patients with straight and type Ⅱ angular foreheads has the best profile when the FA point is located on the GALL line. For patients with rounded and type Ⅰ angular foreheads, a posterior location of the lower third of the face is more desirable than the initial position.

Percepción estética de la posición anteroposterior de los incisivos superiores en relación con la frente / Esthetic perception of the anteroposterior position of upper incisors in relation to the forehead

RESUMEN Introducción: El tratamiento ortodóntico tiene como objetivos fundamentales el logro de relaciones oclusales estables y la mejora en la expresión de la sonrisa. Particularmente, la posición de los incisivos centrales superiores presenta un rol importante en esta expresión y se ha sugerido el uso de referencias extracraneales para su correcta posición tridimensional. Conocer las preferencias de los distintos actores sociales respecto a este factor puede ayudar a las decisiones en la planificación de los tratamientos. Objetivo: Evaluar la percepción estética que ortodoncistas, cirujanos dentistas y personas no expertas tienen de la sonrisa con el incisivo central superior en posición anteroposterior respecto a la frente y en norma lateral. Métodos: Se empleó una fotografía en norma lateral en sonrisa de una mujer peruana con perfil normal y posición anteroposterior del incisivo central superior ideal según el elemento II de la armonía orofacial de Andrews. La fotografía fue modificada digitalmente de tal forma que se obtuvieron imágenes con los incisivos retruídos (- 4 mm) y protruidos (+ 4 mm). Las fotografías fueron evaluadas por un panel conformado por ortodoncistas, cirujanos dentistas y personas no expertas. La evaluación se realizó a través de una escala visual análoga. Resultados: La fotografía con la posición normal del incisivo central superior con respecto a la línea GALL fue mejor valorada por los ortodoncistas (67,658 ± 22,094) y por los no expertos (54,038 ± 20,524). Los cirujanos dentistas consideraron más agradable la posición protruida (60,804 ± 3,626). Se encontraron diferencias significativas entre los grupos de evaluadores y las fotografías (p < 0,05). Conclusiones: Los ortodoncistas mostraron una valoración de la estética más cercana a la norma para la posición anteroposterior de los incisivos. La posición anteroposterior de los incisivos juega un rol importante en la percepción de la estética de la sonrisa en norma lateral(AU)

ABSTRACT Introduction: Orthodontic treatment is mainly aimed at achieving stable occlusal relationships and enhancing the smile expression. The position of the upper central incisors plays a particularly important role in such an expression, and extracranial references have been suggested for its proper three-dimensional position. Awareness of the preferences of the various social actors involved may be useful to make appropriate decisions when planning the treatments. Objective: Evaluate the esthetic perception that orthodontists, dental surgeons and laypeople have of the smile with the upper central incisor in anteroposterior position with respect to the forehead and in lateral norm. Methods: A lateral norm photograph was used of a Peruvian woman with a normal profile and ideal anteroposterior position of the upper central incisor according to element II of Andrews' orofacial harmony. The photograph was digitally modified to obtain images with retruding (- 4 mm) and protruding (+ 4 mm) incisors. The photographs were evaluated by a panel composed of orthodontists, dental surgeons and laypeople. The evaluation was based on a visual analog scale. Results: The photograph with normal position of the upper central incisor with respect to the GALL line was ranked higher by orthodontists (67.658 ± 22.094) and laypeople (54.038 ± 20.524). To dental surgeons the protruded position was nicer (60.804 ± 3.626). Significant differences were found between the groups of evaluators and the photographs (p < 0.05). Conclusions: The esthetic appraisal of orthodontists was closer to the norm for anteroposterior position of incisors. The anteroposterior position of incisors plays an important role in the esthetic perception of the smile in the lateral norm(AU)

Lifting frontal reverso: alternativa para o tratamento da paquidermoperiostose / Reverse frontal lifting: alternative for the treatment of pachydermoperiostosis

Introdução: Paciente com diagnóstico de paquidermoperiostose, apresentando forte manifestação cutânea, impossibilitando a correção do defeito pelas técnicas usuais de lifting facial. O lifting frontal reverso foi a técnica idealizada para o caso. É uma técnica inovadora, não havendo publicação prévia na literatura. Relato de caso: Paciente italiano, sexo masculino, 56 anos, apresentando síndrome de manifestação cutânea, em especial na região frontal da face, com pele inelástica de aspecto coriáceo, que gerava desconforto estético, ensejando um estigma sindrômico. Métodos: A técnica elaborada para este caso envolve incisão, que se inicia na raiz da hélice (ponto A), contorna o supercílio em linha sinuosa distando meio centímetro da implantação dos pelos da sobrancelha, indo até a região da glabela, curvando para a raiz do nariz e indo se encontrar com dimensões idênticas do outro lado. Do ponto A, também ascende uma linha curva inclinando-se para o sentido medial, com uma distância de 2cm. A intenção é diminuir a distância entre a área a ser tracionada e a área de incisão, a fim de obter maior tração, possibilitando assim a correção do aspecto da face em foco. Resultados: A tração caudal do retalho por incisão supraciliar possibilitou a correção do defeito em região frontal sem que houvesse alteração da linha de implantação capilar ou ascensão excessiva das sobrancelhas. Conclusão: A técnica de lifting frontal reverso foi criada para um caso específico de síndrome de paquidermoperiostose. Quando bem indicada esta técnica pode ser utilizada atingindo bons resultados.

Introduction: Patient diagnosed with pachydermoperiostosis, presenting a strong cutaneous manifestation, making it impossible to correct the defect by the usual facial lifting techniques. The reverse frontal facelift was the idealized technique for this case. It is an innovative technique, there being no previous publication in the literature. Case report: Italian male patient, 56 years old, with cutaneous manifestation syndrome, especially in the frontal region of the face, with leathery inelastic skin, which generated aesthetic discomfort, predisposing for a syndromic stigma. Methods: The technique developed for this case involves an incision, which starts at the root of the helix (point A), bypasses the eyebrow in a sinuous line distant half a centimeter from the implantation of the eyebrow hair, going to the glabella, curving towards the nasal root and going to meet identical dimensions on the other side. From point A, a curved line also leans towards the medial direction, at a distance of 2 cm. The intention is to reduce the distance between the area to be pulled and the incision area, in order to obtain more traction, thus enabling the correction of the aspect of the face in focus. Results: Caudal traction of the flap by a supraciliary incision made it possible to correct the defect in the frontal region without altering the capillary implantation line or causing excessive eyebrow rise. Conclusion: The reverse frontal lifting technique was created for a specific case of pachydermoperiostosis syndrome. When correctly indicated, this technique can be used to achieve good results.

Versatility of Forehead Flap in Maxillofacial/Nasal and Intraoral Defects: A Retrospective Analysis

Introduction: Difficulties to find the ideal donor site with perfect matching tissues have always made the reconstruction of facial complex defect a tough problem for surgeons. The main aim of reconstruction is to restore facial contour (esthetics) and function (mastication, deglutition, and speech). Aim: The aim of the study was to analyze the versatility of forehead flap in maxillofacial/nasal and intraoral defects. Materials and Methods: This retrospective study was conducted to analyze the versatility of forehead flap in maxillofacial/nasal and intraoral defects. A total of 25 consecutive patients, of either sex, who required soft tissue reconstruction of the maxillofacial region, including oral cavity and nasal defects due to tumor ablative surgery. Follow-up was done for up to 4 months – 1 year and on every follow-up visit, patients were questioned about the degree of satisfaction, with mouth opening, swallowing, and donor site esthetics. Cosmetic deformity judged subjectively. Results: Of 25 patients, 17 patients were males, 12 patients were above 60 years. Maximum number of site of tumor involvement was noted in cheek 9 patients (36%) and in lower lip 5 patients (20%). About 44% patient had stage 2 tumors and 28% had stage 3 tumors. About 18 patient had adjuvant radiation, 1 patients had chemo RT, and 6 patients had no adjuvant treatment. About 16% of patients had a complication of altered forehead sensation. Conclusion: Forehead flap is a reliable technique for the reconstruction of maxillofacial region defects. It is easy to rise and can provide coverage for wide defects as far as the para mandibular and submandibular regions. Moreover, it does not require patient repositioning.

Effects of transcutaneous electrical acupoint stimulation on pain of patients in expansion process of skin soft tissue dilator on forehead by water injection / 中华烧伤杂志

Objective@#To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on pain of patients in expansion process of skin soft tissue dilator on forehead by water injection.@*Methods@#From June 2016 to June 2017, 100 patients in expansion process of skin soft tissue dilator on forehead by water injection meeting the inclusion criteria were admitted to Outpatient Department of Orthopedic Surgery of Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine. There were 43 men and 57 women among the patients, aged 27 to 55 years, and the prospective randomized controlled study was performed on them. The patients were divided into TEAS nursing group and routine nursing group according to the random number table, with 50 patients in each group. Patients in routine nursing group were performed with routine nursing in every water injection in outpatient department and 2 days later. On the basis of routine nursing, patients in TEAS nursing group were performed with TEAS treatment by responsible nurses in each water injection in outpatient department. The Shangxing, Diwei, and Hegu points were positioned accurately, and electrical stimulation was performed on the 3 points simultaneously by pulse acupuncture treatment instrument, with 30 minutes each time. Two days after every water injection of outpatient department, TEAS nursing was performed at home by patients and their family members under remote guidance of the responsible nurses, with 2 times each day and 30 minutes each time. Besides, follow-up was done by phone by the responsible nurses everyday. The nursing of patients in the 2 groups lasted the whole expansion process. After the expansion process, the overall pain degree and the most severe pain degree of patients during expansion process were scored by numerical rating scale, and the overall comfort degree and its dimensions of patients during expansion process were scored by the responsible nurses every day by simplified Comfort Status Scale. Data were processed with independent sample t test and chi-square test.@*Results@#During expansion process, the overall pain score degree and the most severe pain degree score of patients in TEAS nursing group were (5.4±1.2) and (6.5±1.0) points, which were significantly lower than (6.1±1.3) and (7.5±1.4) points of patients in routine nursing group (t=-2.62, -4.00, P<0.05 or P<0.01). During expansion process, the physiological dimension, sociocultural dimension, psychological spirit dimension, environmental dimension, and total score of the overall comfort degree of patients in TEAS nursing group were (9.6±2.9), (20.1±2.8), (29.1±1.9), (22±3), and (80±6) points, significantly higher than (5.7±2.1), (16.8±2.8), (26.0±2.8), (21±4), and (69±8) points of patients in routine nursing group (t=8.03, 6.35, 7.60, 2.11, 10.64, P<0.05 or P<0.01).@*Conclusions@#TEAS with appropriate intensity, frequency, and duration can alleviate the pain of patients during expansion process of skin soft tissue dilator on forehead by water injection and improve their comfort degree.

Peripheral osteoma on the medial eyebrow successfully extracted while preserving supratrochlear nerve

Osteomas are benign, slow-growing osteogenic lesions frequently found in the craniomaxillofacial region. They can be classified as peripheral, central, or extraskeletal. Reactive mechanisms to trauma or infection, as well as muscle traction, are thought to play a major role in the development of peripheral osteomas. In the present report, a 41-year-old woman presented with a slow-growing, painless mass on her left eyebrow. She had suffered trauma 15 years prior. In the computed tomography scan, a 2.5 × 2 × 0.7-cm radio-opaque tumor was detected just medial to the left supraorbital foramen, and a peripheral osteoma was clinically diagnosed. An elective operation under general anesthesia was planned. Following a suprabrow incision, subcutaneous and intramuscular dissection was performed. In the surgical plane deep to the corrugator muscles and superficial to periosteum, a branch of the supratrochlear nerve was encountered and preserved using a vessel loop. The osteoma beneath the periosteum was extracted in multiple fragments using a chisel and mallet to minimize trauma to the nerve. Contour and facial symmetry were corrected. To use a suprabrow incision, the surgeon must understand neighboring anatomical structures, including the course of the supratrochlear and supraorbital neurovascular bundles. When these structures are located adjacent to tumor lesions, careful surgical maneuvers should be performed to preserve them.

The slant of the forehead as a craniofacial feature of impulsiveness

Objective: Impulsiveness has been the subject of much research, but little is known about the possible relationship between craniofacial anatomy and impulsiveness. The present study was designed to investigate the relationship between one aspect of craniofacial structure (the angle of inclination of the forehead) and impulsiveness. Method: Photographs in profile were obtained from 131 volunteers who had been fined for driving at high speed and were undergoing a court-mandated driving license point-recovery course. They completed the Barratt Impulsiveness Scale (BIS-11), the Impulsive Behavior Scale (UPPS-P), and Zuckerman's Sensation Seeking Scale (V). The angle of the slant of the forehead was measured with a photographic support and a protractor. Results: High positive concordance was found between forehead inclination and 14 out of the 15 impulsiveness factors studied. Conclusions: The angle of inclination of the forehead was significantly associated with self-reported impulsiveness in this sample of traffic violators.

Intradermal Injection of Botulinum Toxin: A Safer Treatment Modality for Forehead Wrinkles

Intramuscular injection of botulinum toxin A (BTXA) is commonly used for the treatment of forehead wrinkles. In practice, physicians often use an intradermal injection for this purpose, as they feel that there is a lower risk of adverse effects compared with intramuscular injection. However, there are no direct comparative studies between those two injection modalities. We conducted a 24-week long, double-blinded, split-face, pilot study of three participants to compare the efficacy and safety of intradermal or intramuscular injection of BTXA for the treatment of forehead wrinkles. Maximum improvement of wrinkles and the time to achieve maximum effect were similar for both methods. The brow level was lower on the intramuscular injection side throughout the follow-up period for all participants. Subjective satisfaction with wrinkles was similar on both sides, but patients felt more heaviness of the eyebrow on the intramuscular side. No serious side effects were noted. In conclusion, the anti-wrinkle effect of BTXA was not significantly different between intramuscular and intradermal injections. However, side effects such as eyebrow ptosis, and heaviness were more prominent after intramuscular injection.

Evaluation of the donor site after the median forehead flap

BACKGROUND: Forehead flaps are useful for facial reconstruction. Studies of these flaps have mostly focused on the results of the reconstruction. However, due to the scarring and changes on the forehead caused by the median forehead flap (MFF), surgeons may be reluctant to perform this flap. Research into the donor site is needed for practical purposes. METHODS: We examined 42 patients who underwent an MFF at Pusan National University Hospital from 1996 to 2016. Based on a retrospective chart review, we examined the occurrence of complications. We also evaluated scars on the forehead using the Vancouver Scar Scale (VSS) and assessed changes in the eyebrow position of 22 patients. RESULTS: No complications occurred in the 42 patients. The mean VSS score of the 22 patients was 2.8±0.79. The ratio of the height of the eyebrow on each side to the distance between the medial canthi increased postoperatively, meaning that both the left and right brows were elevated slightly (P=0.026 and P=0.014). However, the symmetry between the left and right sides did not change (P=0.979). The ratio of the interbrow distance to the distance between the medial canthi decreased slightly, meaning that the interbrow distance narrowed mildly (P < 0.001). Moreover, there were no noticeable changes in the brow position as seen in a photo overlay. CONCLUSIONS: There were no notable complications in the forehead. Forehead scarring was acceptable. No change in brow symmetry was observed via photographic measurements and a photo overlay. Therefore, we propose that the MFF is a useful choice for minimizing scarring or deformation of the donor site.

Primary extracranial meningioma presenting as a forehead mass

Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis. We report a case of primary extracranial meningioma located in the forehead skin of a 51-year-old male.

Forehead reconstruction using modified double-opposing rotation-advancement flaps for severe skin necrosis after filler injection

Varying degrees of complications can occur after hyaluronic acid filler injections. Tissue necrosis due to interruption of the vascular supply is an early complication that can be severe. If the site of tissue necrosis due to the filler injection is the forehead, successfully reconstructing the region without distorting the key landmarks is challenging. We describe the case of a 50-year-old man who experienced widespread forehead skin necrosis after hyaluronic acid filler injection in the glabellar area. We successfully covered the forehead area with a 3×4-cm² midline necrotic tissue using the modified double-opposing rotation-advancement flap method. Although modified double-opposing rotation-advancement flap closure has the disadvantage of leaving a longer scar compared to conventional double-opposing rotation-advancement flap closure, the additional incision line made along the superior border of the eyebrow aids in camouflaging the scar and decreases eyebrow distortion. Therefore, it is believed that the modified double-opposing rotation-advancement flap technique is an excellent tool for providing adequate soft tissue coverage and minimal free margin distortion when reconstructing widespread skin necrosis in the central mid-lower forehead that can occur after filler injection in the glabellar area.

Rare experience of keloidal dermatofibroma of forehead

Dermatofibromas most commonly occur on limbs and rarely occur on the face. Dermatofibroma occurring on the face is associated with unusual clinicopathologic features and a more aggressive clinical course in comparison to typical cases. Additionally, the most common subtype found in previous studies was benign fibrous histiocytoma, with the keloid type being very rare (about 1% of reported cases). The aim of this study was to present our experience with a keloidal dermatofibroma of the face, which is usually missed clinically, and to discuss the treatment of a keloidal dermatofibroma in this location.

Reduction of Closed Frontal Sinus Fractures through Suprabrow Approach

BACKGROUND: The traditional approach for reduction of frontal sinus fractures is coronal incision. Inherent complications of the coronal approach include long scar, hair loss, and long operation time. We describe a simple approach for the reduction of frontal sinus anterior wall fractures using a suprabrow incision that is commonly used for brow lift. METHODS: From March 2007 to October 2016, the authors identified patients with anterior wall frontal sinus fractures treated by open reduction through a suprabrow incision. Only cases with photographic/radiographic documentation and a minimum follow-up of 6 months were included. The incision line was designed to be at the upper margin of the eyebrow. Medical records and radiographic data were retrospectively reviewed. Surgical outcomes, cosmetic results, and complication were assessed. The patient scale of the patient and observer scar assessment scale was used to assess patient satisfaction for incisional scar at the 6-month follow-up. RESULTS: Thirty-one patients underwent fracture reduction through a suprabrow approach during the study period, with a mean follow-up of 41 months. No patients showed any recurrent displacement, eyebrow asymmetry, or infection during follow-up. Thirteen patients reported their forehead paresthesia postoperatively, and 12 of them had preoperative symptom. One patient complained of incisional scar and underwent scar revision. All patients were satisfied with their eyebrow and forehead contour. CONCLUSION: The suprabrow approach allowed for an accurate reduction of the fractures in the anterior wall frontal sinus by providing direct visualization of the fracture. This transcutaneous approach can effectively restore forehead contour with acceptable postoperative complications and patient satisfaction.
