Precise Needle and Cannula Placement in the Forehead During Aesthetic Procedures: Can Device and Angulation Influence Accuracy? A Fresh Frozen Specimen Study.

INTRODUCTION: Myomodulation is a technique aimed at enhancing the dynamics of muscle contraction and relaxation through methods like hyaluronic acid (HA) injection. Achieving optimal outcomes depends on the precise placement of the injected product within the targeted anatomical plane. This is particularly important in the forehead, an area with elevated vascular risk. The selected treatment techniques must ensure both efficacy and safety. This study aims to assess the anatomical precision of HA injections in the forehead using different techniques and devices. METHODS: Four fresh frozen specimens were injected with HA by five experienced board-certified plastic surgeons using three different techniques/devices: (1) a 50 mm, 22G microcannula; (2) a 13 mm, 27G needle with the bevel down at a 45-degree angle; and (3) the same needle positioned at a 90-degree angle. Ultrasound analysis was used to evaluate the precision of each approach. RESULTS: Both the cannula technique and the needle technique with the bevel down at a 45-degree angle consistently delivered the filler to the supraperiosteal layer in 100% of cases without spreading. However, the 90-degree needle technique, despite correct placement on the periosteum, resulted in filler dispersion across multiple layers. CONCLUSION: The accuracy of filler placement in the forehead is influenced by the choice of device and its angulation. It is recommended to use a cannula with the entry point at the frontalis crest or a needle angled at 45 degrees to the skin. The use of a needle at a 90-degree angle should be avoided to ensure precise placement and avoid filler migration.

Supraperiosteal technique protocol for forehead filling with a mixture of calcium hydroxyapatite and hyaluronic acid: Double-blind, randomized controlled clinical trial.

OBJECTIVE: The current study aims to investigate the safety and efficacy of using calcium hydroxyapatite (CaHA) versus CaHA associated with hyaluronic acid (HA) for forehead volume replacement and contour restoration without forehead irregularities. METHODS: This interventional study involved 132 participants in a two-arm, parallel, double-blind trial for forehead treatment using the supraperiosteal technique. Group A received CaHA, and Group B received a combination of CaHA and HA as filler materials. Follow-up assessments occurred at 30 and 180 days, incorporating the 5-point Global Aesthetic Improvement Scale (GAIS) and photographic analysis for forehead volume replacement, contour restoration, and without forehead irregularities. Safety assessments included monitoring adverse events, particularly nodules. RESULTS: The study included all 132 enrolled patients who completed the trial. Applying CaHA in combination with HA resulted in a statistically significant improvement in both GAIS scale scores and the reduction of forehead irregularities. The total incidence of nodules was 3.7%. Group A had four times more occurrences of nodules than Group B. Furthermore, Group B exhibited lower rates of forehead irregularities following the treatment compared to Group A. CONCLUSION: The supraperiosteal application of CaHA and HA for forehead treatment demonstrates superior efficacy in addressing signs of aging compared to the isolated use of CaHA.

Best Practices for the Use of High-Frequency Ultrasound to Guide Aesthetic Filler Injections-Part 1: Upper Third of the Face.

Filler injections in the upper face pose significant challenges due to its complex anatomy and proximity to vascular structures. High-frequency Doppler ultrasound offers real-time visualization of facial anatomy, improving both safety and aesthetic outcomes. This paper presents a detailed overview of the ultrasonographic anatomy of the temples, forehead, and glabella, along with reproducible, ultrasound-guided filler injection techniques for these areas. We use two scanning techniques previously described: "scan before injecting" and "scan while injecting", applicable to subdermal, interfascial, and supraperiosteal planes in the temporal region, as well as the glabella, forehead, and supraorbital region. Ultrasound guidance for filler injections in the upper face can enhance procedural efficacy and safety. By integrating real-time imaging, practitioners can navigate the intricate vascular anatomy more effectively, thereby minimizing the risk of complications. This study highlights the need for ongoing research and continuous education to further refine these techniques and improve patient outcomes.

Increasing precision during neuromodulator injections for frontal rhytids-Using ultrasound imaging to identify the line of convergence.

BACKGROUND: Recent research introduced the concept of the "line of convergence" as a guide for injectors to enhance precision and avoid complications when treating the frontalis muscle with toxins. However, currently, no pre-injection ultrasound scanning is employed to increase precision and reduce adverse events when searching for the line of convergence. OBJECTIVE: To explore the feasibility and practicality of implementing pre-injection ultrasound scanning into aesthetic neuromodulator treatments of the forehead. METHODS: The sample of this study consisted of n = 55 volunteers (42 females and 13 males), with a mean age of 42.24 (10.3) years and a mean BMI of 25.07 (4.0) kg/m2. High-frequency ultrasound imaging was utilized to measure the thickness, length, and contractility of the frontal soft tissue and to determine the precise location of the line of convergence during maximal frontalis muscle contraction. RESULTS: The results revealed that the line of convergence was located at 58.43% (8.7) of the total forehead height above the superior border of the eyebrow cilia without a statistically significant difference between sex, age, or BMI. With frontalis muscle contraction, the forehead shortens in males by 25.90% (6.5), whereas in females it shortens only by 21.74% (5.1), with p < 0.001 for sex differences. CONCLUSION: This study demonstrated the feasibility and practicality of pre-injection ultrasound scanning for facial aesthetic neuromodulator treatments. Knowing the location of the line of convergence, injectors can determine precisely and on an individual basis where to administer the neuromodulator deep or superficial or when the injection location is at risk to cause eyebrow ptosis.

Sagittal Position of the Upper Incisor in Relation to the Forehead in Peruvian Individuals with Different Skeletal Relationships.

AIM: The aim of this study was to determine the sagittal position of the upper incisor considering Andrews' analysis based on the position of the forehead in Peruvian individuals with different skeletal relationships. MATERIALS AND METHODS: This retrospective, cross-sectional study included 212 lateral head radiographs of Peruvian individuals (males: 85, mean age 21.38 ± 6.88, and females: 127, mean age 21.18 ± 6.95), with different skeletal relationships (Class I group = 96, Class II group = 57, Class III group = 59). The values of the ANB, SNA, SNB angles as well as the forehead anterior limit line (FALL) and goal anterior limit line (GALL) points were identified in the radiographs, and then a vertical line was drawn in each point to determine if the upper incisor was positioned forward (protruded), backward (retruded) or within (adequate) these lines. Two trained and calibrated investigators performed all the measurements. The Chi-square test was used to evaluate associations. A p-value < 0.05 was considered statistically significant. RESULTS: Overall, the sagittal position of the upper incisor showed a significant association with the sagittal skeletal relationship (p = 0.001). The upper incisors showed an adequate position (41.7%), protruded position (56.10%), and retruded position (42.40%), for Class I, II, and III skeletal relationships, respectively, as highest percentages in each Class. Statistical significance was found for females only (p = 0.005). CONCLUSION: Skeletal Class I mainly showed an adequate position of the upper central incisor, whereas for Class II a protruded position was most frequently found, and Class III presented a retruded position. CLINICAL SIGNIFICANCE: Andrews' analysis based on the position of the forehead in Peruvian individuals is a valuable tool for orthodontic diagnosis.

Case Report: Pott's Edematous Tumor: Complicated Frontal Sinusitis - An Unremembered Diagnosis.

Pott's Puffy tumor, also called Pott's edematous tumor (PET), is a subperiosteal abscess of the frontal bone, associated with osteomyelitis of the frontal bone. In this paper, we report the case of a 16-year-old patient who presented with headache associated with progressive forehead swelling and fever. Clinical and imaging exams pointed to the hypothesis of PET associated with brain abscess. Patient was submitted to surgical excision of the abscess and treatment of osteomyelitis, with intraoperative findings corroborating the condition. There was a good clinical-radiological recovery associated with prolonged antibiotic therapy and satisfactory follow-up after hospital. PET, which often results from an underdiagnosed or partially treated frontal sinusitis, is a condition that must be promptly recognized and directed to an adequate therapeutic approach due to the risk of serious complications that it entails.

Applied anatomy of the layers and soft tissues of the forehead during minimally-invasive aesthetic procedures.

BACKGROUND: An increasing demand of minimally-invasive aesthetic procedures of the forehead concomitantly leads to higher numbers of adverse events. Adequate application of anatomical knowledge is required to increase safety and efficacy of different minimally-invasive aesthetic procedures in this anatomical region. OBJECTIVE: To describe the layered anatomy of the forehead soft tissues with respect to their thicknesses and how they relate to different minimally-invasive aesthetic treatments. METHODS: A total of n = 85 healthy study participants (69 females and 16 males) with a mean age of 40.84 ± 10.9 years and a mean body mass index of 22.65 ± 2.6 kg/m2 were investigated with ultrasound-based imaging to measure the thickness of different forehead soft tissues. RESULTS: The mean overall soft tissue thickness of the forehead was measured to be 4.18 ± 0.7 mm for the entire study population. Increasing BMI values correlated statistically significantly with increasing thickness of all measured forehead soft tissues with exception of the frontalis muscle. On a statistically significant level, males showed thicker forehead soft tissues than females, with exception of the retrofrontalis fat and the frontalis muscle. CONCLUSION: On basis of the findings obtained in this study, basic treatment principles can be derived and improved for the injection of neuromodulators, hyaluronic acid as well as the application of polydiaxonane (PDO) threads and micro-focused ultrasound. Precise knowledge and thorough understanding of the layers and soft tissues of the forehead is required to guarantee safe and effective procedures in this aesthetically important facial region.

Hemorrhage due to attempted excision of a frontal exophytic lesion: A cautionary tale.

BACKGROUND: Despite mainly benign, exophytic subcutaneous cranial masses present with a myriad of differential diagnosis possibilities, ranging from simple, superficial lesions to complex lesions involving the central nervous system. Although the gold standard imaging modality for the diagnosis of these lesions is magnetic resonance imaging, Doppler Ultrasonography can be a useful, inexpensive, and available tool for evaluation of lesions that could potentially be safely treated in the primary care setting, and lesions that would demand advanced neurosurgical care. CASE DESCRIPTION: This patient presented with a complex exophytic plasmocytoma that was first diagnosed and erroneously approached as a subcutaneous lipoma with surgical resection in an outpatient surgical setting. This interpretive approach resulted in the failure of the procedure due to significant hemorrhage. The patient was immediately referred to neurosurgical care and transferred to our center. Admission doppler ultrasound imaging revealed absence of the frontal bone, the enriched and profuse vascularization, allowing further and proper diagnostic approach and treatment. CONCLUSION: Ultrasound could be a reliable, fast, and simple imaging method aiding practitioners to perform a better workup for patients with exophytic subcutaneous cranial masses.

Histological and Clinical Appraisal of Distribution and Long Acting New Hyaluronic Acid into the Subcutaneous Fat of the Forehead to Improve Horizontal Lines.

BACKGROUND: A new hyaluronic acid (HA) was appraised to improve forehead horizontal lines (FHL). Histological analysis correlated the gel distribution with clinical findings and also with wrinkle depth, 48 h and 12 months after HA application. METHODS: The new filler composed by 24 mg/ml of HA cross-linked with BDDE 2.0 ppm was injected into the subcutaneous fat, just beneath the dermis, through a retrograde backflow injection technique applied in sequence. Biopsies were taken with a 3.0-mm-diameter skin punch before HA application, 48 h and 12 months after HA application for histological evaluation. RESULTS: Subcutaneous application created a compact cylindrical filament as pattern of gel distribution, which acted as strut raising the FHL to the level of the surrounding tissues. Diameter average of the filament 48 h after HA application was 1.18 mm and at month twelve 0.34 mm. The residual amount of the gel at month twelve ensured the long acting of the HA into the subcutaneous fat. FHL depth of 251.83 µm before HA application and 190.20 µm after 12 months indicated that the residual amount of gel at month twelve still projected FHL. CONCLUSION: High cohesivity of HA and low density of forehead subcutaneous fat caused the gel to take the form of a compact cylindrical filament. The small amount of gel still presenting into the subcutaneous fat 12 months after application validated the long acting of the HA. Evidence-based analysis showed that this new filler might be considered a safe alternative for improvement in the FHL.

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)

Giant forehead plasmacytoma as a growing lump in a patient with multiple myeloma.

Extramedullary plasmacytoma represents less than 5% of plasma cell malignancies, 85% corresponding to head and neck masses. Symptoms are related to compressive effects according to location, aesthetics issues and can be misleading associated with soft tissue disorders. In this case report, we discuss a 70-year-old woman who presented with a 3-month history of a growing painless forehead lump and confusion, for which she had an emergent simple head computed tomography scan. The images revealed a well-defined mass eroding the frontal bone with multiple lytic lesions that were also found along with long bones radiography. The mass biopsy showed a monomorphic plasmatic cell infiltrate, bone marrow studies confirmed the diagnosis of a light chain secreting multiple myeloma. Extramedullary plasmacytoma is a very unusual first presentation form of multiple myeloma and represents a clinical and radiological challenge. A systematic approach of lytic bone lesions along with the differential diagnosis of head masses are skills the clinician should develop to promptly recognize this condition considering further complications of delayed treatment. In this case, the histopathological confirmation allowed the patient to avoid neurosurgery and the early start of systemic chemotherapeutic treatment.

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.

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.

Ácido hialurônico no rejuvenescimento do terço superior da face: revisão e atualização - Parte 1 / Hyaluronic acid in the rejuvenation of the upper third of the face: review and update - Part 1

Nos últimos anos houve grande avanço nas técnicas não invasivas de rejuvenescimento facial. O maior entendimento das alterações anatômicas envolvidas no processo do envelhecimento foi acompanhado por rápida evolução na forma de abordar essas alterações e pela expansão de substâncias e tecnologias usadas nessa abordagem. Com relação ao arsenal de substâncias usadas para rejuvenescimento, o terço superior da face, era antes território quase exclusivo dos neuromoduladores. Atualmente, os preenchedores vêm ocupando lugar de destaque, especialmente aqueles à base de acido hialurônico (AH), porque são seguros e produzem resultados imediatos e duradouros, porém reversíveis. O objetivo deste primeiro artigo é oferecer breve revisão da literatura e atualização sobre o uso de preenchedores de AH no rejuvenescimento do terço superior da face, enfocando as regiões da fronte e da glabela.

In recent years there has been a breakthrough in non-invasive techniques of facial rejuvenation. The greater understanding of the anatomical changes involved in the aging process was accompanied by rapid evolution in how to address these changes and the expansion of substances and technologies used in this approach. Of the arsenal of substances used for rejuvenation, the upper third of the face was before an almost exclusive territory of neuromodulators. Currently, fillers have stood out, especially those based onhyaluronic acid (HA), because they are safe and produce immediate and lasting ­ but reversible ­ results. The objective of this first article is to provide a brief literature review and update on the use of HA fillers in the rejuvenation of the upper third of the face, focusing on the forehead and glabella areas.

Forehead reduction in patients with precapillary incision: 10 years of experience / Redução frontal em pacientes submetidos à incisão pré-capilar: 10 anos de experiência

Introduction: The long forehead gives a less harmonious appearance, seems disproportionate and characterizes the aging face. Surgical procedures for frontal reduction with precapillary incision present insightful information and provide harmonious and pleasant restoration of the frontal region. This study evaluated results obtained in patients who underwent frontal reduction using precapillary incision at Daher Hospital plastic surgery service within the last ten years. Methods: This was a retrospective longitudinal study. The surgical technique entailed a careful dissection of the bilateral supraorbital ridge. The scalp was dissected in the parietoccipital region in order to easily move forward the flap. The vigorous hemostasis and resection of excessive flap were performed. In the end, synthesis of plans were performed. Results: The age of patients ranged from 48 to 76 years, the mean age was 58 years. Mean surgical time was 3 hours and 38 minutes. No complications were seen such as hematoma, flap necrosis, supratrochlear nerve injury, alopecia, infections, deep vein thrombosis, pulmonary embolism and/or dehiscence. Four patients (7%) had seroma that was drained. The symmetric of eyebrows and scars positioning was considered satisfactory in both assessment by patients and the technical evaluator. Conclusion: The aesthetic results in patients who underwent frontal reduction by precapillary incision were satisfactory. The choice of the ideal patient was crucial for success of the surgery.

Por fim, realiza-se a síntese por planos. Resultados: A faixa etária das pacientes variou de 48 a 76 anos, com média de 58 anos. O tempo médio operatório foi de 3 horas e 38 minutos. Não foram observadas complicações como hematoma, necrose do retalho, lesão do nervo supratroclear, alopécia, infecções, trombose venosa profunda, embolia pulmonar e/ou deiscências. Quatro pacientes (7%) apresentaram seroma, os quais foram todos drenados. A simetrização das sobrancelhas e a posição das cicatrizes foram consideradas satisfatórias tanto pela avaliação feita pelos pacientes quanto pela avaliação técnica. Conclusão: Os resultados estéticos obtidos em pacientes submetidos à redução frontal pela incisão pré-capilar foram satisfatórios. A escolha do paciente ideal foi fundamental para o bom sucesso operatório.

Complex nasal reconstruction after paracoccidioidomycosis infection - Case report

Paracoccidioidomycosis is an infectious disease whose etiological agent belongs to the Paracoccidioides genus. Although it affects primarily the lungs, it can spread to other tissues, including the skin and mucous membranes. Despite the clinical treatment for this disease, scarring can produce sequelae, manifesting as anatomical and functional deformities of the face. We present a case of extensive, nasal unaesthetic and functional sequelae resulting from paracoccidioidomycosis, reconstructed using the paramedian forehead flap in three stages, through the regional unit principles.

Introduction: The nasal reconstruction may require the use of flaps from the forehead, especially when other simpler repair techniques can’t be performed. This study shows the usefulness of this technique. MATERIALS AND METHODS: An observational study, retrospective, transversal, of consecutive case series, which includes adult patients who underwent nasal reconstruction with paramedian forehead flap over a period of two years. RESULTS: Eight patients were treated by this technique with age range between 53 and 76 years. The nasal reconstructions were performed in two or three times with success. No postoperative complications were noted. CONCLUSION: The paramedian forehead flap has a place in the treatment armamentarium for nasal reconstruction.
