bookPart Ferimentos específicos na face(2015) FRIEDHOFER, Henri; JúNIOR, Jonas Eraldo de Lima; MUNHOZ, Alexandre Mendonça- Xantogranuloma juvenil gigante: acometimento palpebral difuso e simultâneo(2019) FRIEDHOFER, HENRI; VASSILIADIS, ANETA HIONIA; LOBATO, RODOLFO COSTA; MOHR-BELL, VANESSA ANNE; JESUS, MATEUS NEVES DA SILVA DE; SCAPOLAN, MAIRA BENITO; GEMPERLI, ROLFABSTRACT Juvenile xanthogranuloma (JXG) is the most common benign tumor of the group of non-Langerhans histiocytic proliferative diseases. Lesions; 2 cm are considered giant JXG, with reports of lesions of up to 18 cm. Oculopalpebral lesions may require surgical treatment to control symptoms. This study reports a case of an 8-year-old boy who had four eyelids and the middle third of the face affected by giant JXG. He underwent three resections, one of which was of great depth that required a full-thickness skin graft directly on the levator palpebrae superioris aponeurosis. Subsequently, three fat-grafting procedures were performed and adequate functional and aesthetic results were achieved without lesion recurrence.
- Reconstrução após ressecção bipalpebral com preservação do globo ocular: desafio estético e funcional(2021) FRIEDHOFER, HENRI; LOBATO, RODOLFO COSTA; VASSILIADIS, ANETA HIONIA; SCAPOLAN, MAIRA BENITO; JESUS, MATEUS NEVES DA SILVA DE; RODRIGUEZ, JUAN FELIPPE GUIMARÃES URCIOLI MOSQUERA DE; TARIKI, JOSÉ YOSHIKAZU; GEMPERLI, ROLFABSTRACT Introduction: Eyelid reconstruction can be performed by primary closure, a graft of different lamellae, and local and/or regional flaps, single or combined. This reconstruction becomes more complex when the upper and lower eyelids are resected to total thickness, and the eyeball is preserved. The objective is to report the techniques used for periorbital reconstruction in bipalpebral resection cases (upper and lower) with preservation of the eyeball by the Group of Orthopalpebral Surgery of the Division of Plastic Surgery and Burns of HCFMUSP. Methods: All cases that met the inclusion criteria from 2000 to 2019 were reviewed, and epidemiological, surgical, and postoperative follow-up data were described. Results: Only two cases were submitted to total exeresis of the periorbital tissue and remained susceptible to eyeball preservation. Both were reconstructed with frontal flaps with complete occlusion of the eyeball at the first moment, followed by the release in stages, keeping the globe viable after reconstruction completion. Discussion: Similar reports are scarce in the literature, and, in these cases, surgical results were functionally acceptable but with significant aesthetic limitations. Conclusion: We suggest a new option for total reconstruction of the upper and lower eyelid (with a single pedicular flap, devoid of connective graft and in multiple stages) that protects and conserves the eyeball during the various stages of surgery. The results were functionally favorable, considering the severity of the cases.
- Alternative Surgical Treatment of Paralytic Lagophthalmos Using Autogenic Cartilage Grafts and Canthopexy(2013) FRIEDHOFER, Henri; COLTRO, Pedro Soler; VASSILIADIS, Aneta Hionia; NIGRO, Marcelus Vinicius; SAITO, Fabio Lopes; MOURA, Tatiana; FARIA, Jose Carlos; FERREIRA, Marcus CastroPurpose: This study aims to analyze the use of autogenic auricular cartilage grafts as weight for the upper eyelid in conjunction with lateral canthopexy for patients with mild paralytic lagophthalmos. This procedure was also accompanied by elevation of the lower eyelid using the cartilage graft for moderate cases. Methods: We conducted a retrospective study including case series of 30 patients with paralytic lagophthalmos from 1997 to 2010. For mild cases, cartilage from the auricular scapha was placed in pretarsal space of the upper eyelid and cartilage from the concha was inserted in preaponeurotic space and then sutured to the levator aponeurosis in conjunction with lateral canthopexy. For moderate cases, lower eyelid was also elevated by suturing cartilage graft to tarsum and resting it by the inferior orbital rim. Results: All patients had some degree of keratopathy before the intervention. After treatment, they presented with evident clinical improvement, reduction of eye symptoms, and resolution of keratopathy. During the mean postoperative follow-up of 37.3 months, none of the patients presented with cartilage graft exposition, reabsorption, visibility, infection, or warping. Complete eye closure was achieved in 24 (80%) patients, whereas the remaining 6 (20%) patients had residual asymptomatic lagophthalmos. Conclusions: The intervention using autogenic auricular cartilage grafts explained in this study was only effective for the treatment of mild and moderate cases of paralytic lagophthalmos. This outpatient surgery is associated with low morbidity and achievement of functional and aesthetic improvement.
- Tricoadenoma palpebral: tratamento cirúrgico associado à blefaroplastia estética(2012) FRIEDHOFER, Henri; SÁ, Álvaro Júlio de Andrade; MESQUITA, Maria Cristina de Paula; LANDMAN, Gilles; MESQUITA, Arthur de Paula AmorimTrichoadenoma is a benign cutaneous tumor that is asymptomatic, rare, and slow growing. There are few cases reported in the literature, and we could only identify one description of trichoadenoma occurring in the eyelid area. We describe the case of a patient with trichoadenoma in the outer corner of the lower eyelid that we treated with surgical excision associated with blepharoplasty.

- Correction of Severe Ptosis with a Silicone Implant Suspensor: 22 Years of Experience(2012) FRIEDHOFER, Henri; NIGRO, Marcelus V. A. S.; STURTZ, Gustavo; FERREIRA, Marcus C.Background: Patients with severe ptosis caused by poor or absent function of the levator muscle but with good frontalis muscle excursion usually benefit from a frontalis sling procedure. This is currently carried out using organic or inorganic material to connect the upper eyelid to the frontalis muscle. Methods: The aim of this study was to evaluate retrospectively 112 patients who underwent frontalis sling procedures between 1989 and 2011 using a preformed silicone implant suspensor to correct severe ptosis. Results: The results obtained using this technique were good or fair in 95.54 percent of the cases and poor in 4.46 percent of the cases. The authors discuss the results of the study and the cases in which the procedure should be indicated and highlight the advantages of the method. Conclusion: The availability of this low-cost sterile device, together with the fact that it is ready to use, requires less invasive surgery, saves time, and is sufficiently versatile to allow adjustments to be made at any time, makes the silicone eyelid sling an attractive choice for correcting ptosis.
