Microsurgical replantation after forehead avulsion - success or failure? A case report.

In this article we would like to present, to our best knowledge, the very first published replantation of a forehead/part of a forehead as a single unit. The patient is a 57-year-old male smoker who sustained an avulsion forehead injury after a dog bite. Replantation was performed using microanastomosis of the supratrochlear vessels with restoration of good blood circulation after the procedure. Unfortunately, 5 days after the surgery, ischemia of the flap occurred followed by successful acute revision surgery. Nevertheless, the day after the ischemia reoccurred due to the time that passed, circumstances and unfavorable conditions affecting the sutured vessels, no further revision surgery was indicated. Observation continued and eventual wound necrosis after demarcation was left to be treated with skin grafting or per secundam intentionem. Only partial necrosis of the flap occurred, approximately 50%, which was subsequently treated with a full-thickness skin graft with very good results leading to the satisfaction of the patient.

Melanotic neuroectodermal tumor of infancy: a case report.

BACKGROUND: Melanotic neuroectodermal tumor of infancy (MNTI) is a rare clinically benign, pigmented, tumor of neural crest origin which commonly occurs in the maxilla. It is a rare tumor that may pose difficulty in differentiating from other malignant round cell tumors. CASE PRESENTATION: A 5-month-old Ethiopian infant presented with a mass on his forehead. A wide excision of the lesion was done and subjected to histopathologic evaluation. The histologic and immunohistochemistry for synaptophysin studies confirmed that the infant was having MNTI. The patient was followed and there was no sign of recurrence at the 6th and 9th months of follow-up. CONCLUSION: MNTI should be considered as a differential diagnosis for tumors occurring in the head region in infants and prolonged follow-up may be needed to check for possible recurrence of the tumor.

A 16-Year-Old Girl with Sinonasal Cutaneous Fistula Following Excision and Radiotherapy for Rhabdomyosarcoma Requiring Reconstructive Surgery Using an Expanded Forehead Flap.

BACKGROUND Sinonasal rhabdomyosarcoma (RMS) is a rare malignancy in children and adolescents. It is aggressive and locally invasive, and can require local postoperative radiotherapy. This report presents the case of a 16-year-old girl with a sinonasal-cutaneous fistula following excision and radiotherapy for rhabdomyosarcoma, which required reconstructive surgery using an expanded forehead flap. CASE REPORT We report the case of a16-year-old girl who was referred to our clinic with sinonasal-cutaneous fistula. Prior to presentation at our department, she presented with bilateral intermittent nasal congestion 3 years ago. At a local hospital, orbital computed tomography and nasal endoscopic biopsy revealed an embryonal rhabdomyosarcoma (ERMS). One month later, skull base tumor resection, nasal cavity and sinus tumor resection, and low-temperature plasma ablation were performed at a local hospital. Two weeks after the operation, the patient received intensity-modulated radiation therapy for a total of 50 Gy. Chemotherapy started 15 days after radiotherapy, using a vincristine, dactinomycin, and cyclophosphamide (VAC) regimen. Approximately 1 month later, an ulcer appeared at the nasal root and the lesion gradually expanded. The patient was referred to our hospital due to the defect. Firstly, a tissue expander was implanted at the forehead for 7 months. Then, the skin around the defect was trimmed and forehead flap was separated to repair the lining and external skin. The flap survived well 1-year after the operation. CONCLUSIONS This report highlights the challenges of post-radiation reconstructive surgery and describes how an expanded forehead flap can achieve an acceptable cosmetic outcome in a patient with a sinonasal-cutaneous fistula.

The Two-Stage Folded Paramedian Forehead Flap Without Cartilage Grafts for Full Thickness Distal Nasal Defects: A Review of 35 Patients.

BACKGROUND: Full thickness defects of the ala, soft triangle, and nasal tip involving the nasal lining have traditionally been repaired with the three-stage folded paramedian forehead flap (FPFF), with a cartilage graft for support. For similar defects, the authors utilize the two-stage FPFF without cartilaginous support which provides reproducible functional and aesthetic results.  Objective: To describe the authors’ experience with the two-stage FPFF, including outcomes, complications, and design modifications to enhance functional and aesthetic success.  Methods: An IRB-approved retrospective database review of FPFF was performed at two sites. Using postoperative photographs, outcomes were assessed by blinded non-investigator dermatologist raters using a modified observer scar assessment scale. RESULTS: Thirty-five patients were reconstructed using the two-stage FPFF without cartilage grafts. Subjective assessment of scar vascularity, pigment, relief, and thickness by 3 independent reviewers yielded an overall cosmesis score of 8.4±1.9 (out of 40). CONCLUSION: The two-stage FPFF without cartilage grafts is a reliable, cosmetically elegant repair that can provide optimal functional and aesthetic results for complex unilateral distal nose defects.J Drugs Dermatol. 2024;23(4): doi:10.36849/JDD.7358.

Decision Making in Nasal Reconstruction: When to Use the Forehead Flap?

In this review, the paramedian forehead flap indications and uses are reviewed, specifically examining clinical situations where patient selection is important. In these settings, a preoperative discussion with a patient regarding surgical expectations and goals in the setting of their defect is paramount. The authors review the literature regarding the psychosocial aspects of major nasal reconstruction and review preoperative discussion points that are key to a well-informed patient and improved patient satisfaction through the nasal reconstructive process.

Nasal Reconstruction of Large Defects Without a Forehead Flap.

Defects over 2.0 to 2.5 cm may often require repair with a multistaged forehead flap. However, in some such defects, other options may be available. In this article, the author will review some of these options.

Nasal Lining Reconstruction with Prelaminated Forehead Flap.

A successful nasal reconstruction relies heavily on a stable internal lining. Larger defects pose unique challenges for internal lining reconstruction as obtaining tissue of adequate size while maintaining airway patency is difficult. The prelamination technique uses a staged skin graft to the paramedian forehead flap prior to transfer. As such, a composite flap can be later transferred to reconstruct internal and external nasal defects concomitantly. This article reviews the current background, techniques, and clinical considerations in the use of the prelaminated forehead flap for nasal lining reconstruction in partial to total nasal defects.

Total Nasal Reconstruction: Advances in Free Tissue Transfer for Internal Lining and Structural Support.

Total nasal reconstruction is a complex challenge due to the need to establish new internal lining, internal structural support, and external skin covering that is both functional and esthetic. The medial femoral condyle corticoperiosteal free flap represents an innovative option for restoration internal structure and internal nasal lining. When used in conjunction with a paramedian forehead flap, acceptable results in both function and esthetics can be achieved.

Nuances in Forehead Flap Reconstruction for Large Nasal Defects.

The forehead flap is a time-tested and robust resurfacing flap used for nasal reconstruction. Owing to its excellent color and texture match, acceptable donor site morbidity, and robust and independent blood supply that can support both structural and internal lining grafts, this flap remains the workhorse flap for resurfacing large nasal defects. Various nuances of this technique relating to defect and template preparation, flap design, flap elevation, flap inset, donor site closure, and pedicle division are discussed in this article. These nuances are the guiding principles for improved outcomes using a forehead flap for the reconstruction of large nasal defects.

Reconstruction of Large Composite Defects Extending Beyond the Nose.

Nasal reconstruction remains one of the most challenging surgeries for facial plastic and reconstructive surgeons. The addition of defects extending beyond the nose adds a layer of complexity to an already technically demanding surgery. This article will focus on the management of composite defects extending beyond the boundaries of the nose. Surgeons need to have a variety of techniques at their disposal. These complex defects often require multiple local flaps, multiple stages, and, in select cases, free tissue transfer.

Revision Nasal Reconstruction After Previous Forehead Flap.

Reconstructing the nose poses considerable challenges, even for the most skilled surgeons. Significant nasal reconstructions often require later revisions to address persistent issues in both form and function, and it is crucial to discuss this possibility with the patient before embarking on the reconstructive process. Minor revisions can often be managed by making direct incisions between nasal subunits, coupled with soft tissue sculpting or the use of structural grafts for augmentation. When minor adjustments prove insufficient, the initial reconstruction may need to be entirely revised with a second forehead flap.

Nerve Block Guided by Anatomic Landmarks Only Reduces Pain in Botulinum Toxin Type A Treatment for Glabellar and Forehead Wrinkles.

BACKGROUND: Botulinum toxin type A is widely used to treat glabellar and forehead wrinkles, but the pain caused by multiple injections often deters patients from receiving long-term treatment. Despite several methods used to alleviate this pain, consistency and effectiveness remain a challenge. Therefore, this study aimed to evaluate the effectiveness and safety of nerve block guided by anatomic landmarks only in reducing pain associated with botulinum toxin type A injections. PATIENTS AND METHODS: Between 2018 and 2022, the study enrolled 90 patients divided into 3 groups: the nerve block group (n = 30), the lidocaine cream group (n = 30), and the control group (n = 30). In the nerve block group, a landmarks-based technique was used to perform the nerve block. The study collected general information and comorbidities, and recorded pain at each point and time spent on preparation and treatment for each patient's forehead and glabellar area on each side. Patient-reported outcomes and complications were followed up at 2, 4, and 12 weeks after the injections. RESULTS: The nerve block group had significantly lower total pain scores in all regions compared to the lidocaine cream and control groups (P < 0.01). There were no significant differences in patient-reported outcomes between the groups at any follow-up point. Additionally, the complication rates related to injection were low and comparable among the 3 groups. CONCLUSIONS: Nerve block guided by anatomic landmarks only is a safe, effective, and consistent approach to reduce pain during botulinum toxin type A treatment for glabellar and forehead lines. This technique may offer advantages over other methods used to alleviate the pain associated with these injections.

A Phase III Clinical Study of the Efficacy and Safety of Botulinum Toxin Type A (MASPORT) with DYSPORT for the Treatment of Glabellar Lines.

BACKGROUND: Botulinum toxin type A is a widely used treatment of facial wrinkles. The objective of this study was to compare the efficacy and safety of a new botulinum toxin type A (Masport [abobotulinum toxin A], MasoonDarou Co) with DYSPORT® for the treatment of glabellar lines. METHODS: 262 subjects with moderate-to-severe glabellar lines received either a fixed dose of 50 units of MASPORT® or DYSPORT® (Ipsen Company, England). Subjects were followed up at 14, 30, 60, 90 and 120 days after injection. Efficacy was assessed by investigator at maximum frown and rest and also by Subject Global Assessment of Change (SGA). The responders were defined as persons with +2 grade improvement from baseline for both investigator and patient assessment. The occurrence and duration of adverse effects were recorded up throughout the study. RESULTS: According to the investigator evaluations, the responder rate at maximum frown were 94.5% for MASPORT and 95.6% for DYSPORT group on day 30 and at rest were 85.45% and 85.68% for MASPORT and DYSPORT group, respectively. According to the subject self-assessment, the proportion of responders in MASPORT group at day 30 was 95.28% versus 97.04% for DYSPORT group. No serious drug related adverse effect was recorded in either study groups, and the rates of adverse effects were similar for both groups. CONCLUSION: Abobotulinum toxin A [MASPORT] is equally safe and effective as commercial product [DYSPORT] for the treatment of glabellar lines with the dose of 50 units, up to 120 days.

Single-Step Full-Face Surgical Treatment of the Facial Profile.

The present study was performed to describe how much affordable, feasible, and straightforward is the approach the authors called "single-stage full-face surgical profileplasty," tailored to greatly improve the surgery of the facial profiling setting and achieve complete profile correction at the same time. From January 2010 to May 2019, 113 patients (95 females and 18 males; aged 19 - 63 years) were surgically treated for full-face profile amelioration. Profile correction was performed by using a combination of five procedures out of other various previously experienced: forehead fat grafting, rhinoplasty, lip fat grafting, genioplasty, and submental liposuction. All patients were assessed at 1, 3, 6, and 12 months following surgery for assessing the surgical profile treatment (SPT) outcome and any possible side effects of the combined treatment. Facial profile stability at 1 year was taken as the completion point of this treatment. Arnett et al's "Soft Tissue Cephalometric Analysis" (1999) was used to clinically evaluate the soft tissues before and after the SPT. Patients' satisfaction was measured with the Client Satisfaction Questionnaire-8" at 3 and 12 months after surgery. Statistics were used for Arnett et al's evaluation. Almost all the values were consistent and reached the normal ranges indicated by Arnett et al (p < 0.001), confirming that the desired results of the surgical profileplasty have been achieved. Single-stage full-face surgical profile treatment helps in correcting faults of the global facial deformity, in every single treated area, providing an overall improvement in facial aesthetics and harmony. Obtaining the simultaneous correction in the whole face has also the advantage of avoiding multiple surgical procedures, reducing postoperative discomfort, and the overall risks for the patient due to multiple surgical and anesthetic procedures.

Temporoparietal Fasciocutaneous Island Flap for Forehead and Anterior Scalp Reconstruction.

Background: Forehead and anterior scalp large defect reconstruction is challenging and often requires skin grafting. Objective: To measure the advancing distance and the survival of the temporoparietal fascia (TPF) island flap in forehead and anterior scalp reconstruction. Methods: The study design was a retrospective case series. Participants included all patients who had undergone TPF island flap for forehead and anterior scalp defects of 3 cm and greater from 2009 to 2021. Flap advancing distance and vascular compromise were analyzed. Results: Patient's average age at time of surgery was 73 (standard deviation [SD] 14) years with more males (n = 24, 67%) than females (n = 12, 33%). Of 36 patients, 24 had forehead and 12 had anterior scalp defects, 26 cases had a full TPF island flap, and 10 cases underwent the partial island modification. Flap edge ischemia occurred in two cases (6%) and complete ischemia occurred in one case (3%). The median flap advancing distance was 3.7 cm (SD 1.2). Conclusions: In this 12-year review, we found that the TPF island flap is able to advance up to 7.5 cm and thus is an effective reconstruction for medium to large forehead and anterior scalp defects.

Anatomical Proposal for Botulinum Neurotoxin Injection for Horizontal Forehead Lines.

SUMMARY: The frontalis muscle is situated across the forehead and is a representative target muscle for botulinum neurotoxin (BoNT) injections aimed at treating horizontal wrinkles in this region. However, a lack of anatomical information regarding the shape and thickness of the frontalis may lead to unexpected adverse effects, such as ptosis and samurai eyebrows, caused by the lack of detail on anatomical variation. Achieving the maximum effect using the minimal amount of BoNT requires a precise injection into the frontalis muscle. The anatomical factors associated with BoNT injection into the frontalis muscle have been reviewed in the current study. Up-to-date understanding of the localization of the BoNT injection point according to an updated understanding of the anatomy leads to more accurate localization of the injection point into the frontalis muscle. Optimal injection sites have been provided for the frontalis muscle, and the injection method has been recommended. The authors suggest optimal injection sites according to the external anatomical landmarks of the forehead. Furthermore, these proposals could aid in a more precise procedure that avoids the deleterious effects of BoNT.

The Dynamic Changes in Skin Thickness of Forehead during Tissue Expansion.

In addition to providing extra flap size, the tissue expansion process also brings changes in flap thickness. This study aims to identify the changes in the forehead flap thickness during the tissue expansion period. Patients undergoing forehead expander embedment from September 2021 to September 2022 were included. The thickness of the forehead skin and subcutaneous tissue were measured with ultrasound before and 1, 2, 3, and 4 months after expansion. Twelve patients were included. The average expansion period was 4.6 months, and the mean expansion volume was 657.1 mL. The thickness of skin and subcutaneous tissue in the central forehead changed from 1.09 ± 0.06 to 0.63 ± 0.05 mm and from 2.53 ± 0.25 to 0.71 ± 0.09 mm, respectively. In the left frontotemporal region, skin and subcutaneous tissue thickness changed from 1.03 ± 0.05 to 0.52 ± 0.05 mm and 2.02 ± 0.21 to 0.62 ± 0.08 mm. On the right side, skin and subcutaneous tissue thickness changed from 1.01 ± 0.05 to 0.50 ± 0.04 mm and 2.06 ± 0.21 to 0.50 ± 0.05 mm. This study measured the dynamic changes in the thickness of the forehead flap during expansion. The thickness of the forehead flap decreased the fastest in the first 2 months of expansion, and the changes in skin and subcutaneous thickness slowed down in the third and fourth months and tended to a minimum value. Additionally, the thickness of subcutaneous tissue decreased greater in magnitude than the dermal tissue.

Estimating the Change in Facial Subunits During Positive and Negative Facial Expression Using Three-Dimensional Stereophotogrammetry Facial Analysis.

Background: A more refined and clinically related facial expression analysis is required for patients who wish to be perceived more emotionally positive. Objective: To measure the change in skin vector and volume in facial subunits when expressing positive expression (happiness) compared with negative expressions (sadness, fear, disgust, and anger), using three-dimensional (3D) stereophotogrammetry analysis. Methods: This study took 3D photographs of 20 volunteers' face at rest and during positive and negative expression. The directions of skin vector and volume changes in each facial subregion were recorded and calculated. Results: In the positive expression, 78.3% (95% confidence interval [CI] 66.8-89.9) of the medial midfacial subregions presented superolateral vector and volume increase, whereas volume decrease in 82.5% (95% CI 78.5-86.5) of the lip subregions could be observed. In the negative expression, the vector changes were predominantly inferomedial in 26.0% (95% CI 15.4-36.5) of the forehead and 36.8% (95% CI 33.2-40.3) of the upper eyelid subregions, whereas volume increases in 34.0% (95% CI 30.4-37.7) of the upper eyelid subregions were observed. Conclusions: This 3D stereophotogrammetry analysis presents the morphological difference between the positive and negative expression.

Choosing Upper Blepharoplasty, Infra-brow Lift, and Forehead Lift in Asians: An Algorithmic Approach from Personal Experience.

BACKGROUND: Eyelid surgery is a cosmetic procedure performed worldwide in the field of plastic surgery. However, achieving optimal outcomes for the upper eyelids presents a challenge, necessitating careful patient selection and appropriate surgical choices. OBJECTIVES: This article aims to provide recommendations for selecting the most suitable surgical procedure among three commonly performed treatments for aged upper eyelids. METHODS: A retrospective cohort study was conducted from October 2020 to May 2022, involving 518 patients. Pre- and postoperative photographs were analyzed to evaluate changes in the distance between the eyelids and brows. Notably, patients who habitually use the frontalis muscle to manage upper eyelid redundancy showed significant variations in the lid-brow distance after eyelid surgery. RESULTS: The study confirmed that addressing skin laxity through upper blepharoplasty or infra-brow excision reduced the stimulus for frontalis activity, resulting in true brow ptosis. However, the degree of compensatory frontalis movement differed among individuals, and changes in the lid-brow distance observed before and after the photos were influenced by various factors. As a result, obtaining clear numerical data regarding the changes in the lid-brow distance following eyelid surgery proved challenging. Nevertheless, after analyzing 518 cases, the author has classified the patients into three groups, which can contribute to more predictable and satisfying outcomes. CONCLUSION: Based on the analysis of pre- and postoperative results from 518 patients, this study recommends specific strategies to enhance patient satisfaction. The proposed treatment algorithm may assist beginner surgeons in avoiding angry or tired-looking eyes after periorbital rejuvenation.
