Rehabilitation of pediatric retinoblastoma patients with ocular prostheses and their subsequent modifications: A 15-year retrospective study.

PURPOSE: Enucleation is a common treatment modality performed for pediatric retinoblastoma patients, and the resultant defects are reconstructed using an ocular prosthesis. The prostheses are modified or replaced periodically, as the child develops due to orbital growth and patient-error. The purpose of this report is to evaluate the replacement frequency of prostheses in the pediatric oncologic population. METHODS: A retrospective review was completed by the two senior research investigators, of patients that had ocular prostheses fabricated following enucleation of their retinoblastoma from 2005 to 2019 (n = 90). Data collected from the medical records of the patient included the pathology, date of surgery, date of prosthesis delivery, and the replacement schedule of the ocular prosthesis. RESULTS: During the 15-year study period, 78 enucleated observations (ocular prosthesis fabricated) were included for analysis. The median age of the patients at the time of delivery of their first ocular prosthesis was calculated to be 2.6 years (range 0.3-18 years). The median time to the first modification of the prosthesis was calculated to be 6 months. The time to modification of the ocular prosthesis was further stratified by age. CONCLUSION: Pediatric patients require modification of their ocular prostheses throughout their growth and development period. Ocular prostheses are reliable prostheses with predictable outcomes. This data is helpful to set an expectation among the patient, parent, and provider.

Custom-made ocular prosthesis: solitary method to improve facial aesthetics (a case report).

Loss of facial structures has a physical, social and psychological impact on affected individuals. Ocular trauma caused by assaults, falls, road traffic accidents, and household or work-related accidents may necessitate eye enucleation. Enucleation is also performed to treat severe infections of the eye, intraocular tumours and painful blind eyes. This procedure can result in post-enucleation socket syndrome with facial disfigurement and severely compromising facial aesthetics. Our patient complained of facial disfigurement because of a defect associated with the right eye. History and clinical features were suggestive of post-enucleation socket syndrome. The defect was rehabilitated with an ocular prosthesis. The rehabilitation procedure provided satisfactory results and a happy patient with good aesthetics. Maxillofacial prosthesis can restore and rehabilitate lost facial structures with artificial substitutes and helps in regaining patient´s natural appearance, the health of adjoining structures and subsequently, provide physical, social and psychological well-being.

Prostetic Rehabilitation of an Eye Globe: Case Report.

INTRODUCTION: The lack of an eye has an immediate and long-term impact on a patient's life. AIM: The aim of this study is to show a case of prosthetic rehabilitation of an eyeball. CASE REPORT: Male patient, 60 years old, sought care at the Oral Oncology Center of the São Paulo State University "Júlio de Mesquita Filho", for the rehabilitation of the orbital cavity with an acrylic eye prosthesis. This prosthesis was made with thermopolymerizable acrylic resin and hand painted iris with oil paint on cardboard. The prosthesis was installed after finishing and polishing and the hygiene and general care instructions were explained. CONCLUSION: In the present case, the patient was satisfied with the aesthetics and comfort of the prosthesis, which demonstrates the success of the treatment.

Prosthodontic management of maxillofacial cases: a case series.

Maxillofacial prosthetics is an important and recognized sub-discipline of prosthodontics that forms a key component of postgraduate training programmes. General dentists have a role to play in the management of maxillofacial defect patients even though treatment usually requires a multidisciplinary approach in an institutional environment. Maxillofacial prosthetic cases frequently present with complex histories but simple patient goals. The conservatively managed implant-retained auricular prosthesis, speech aid prosthesis and orbital prosthesis cases described in this report were completed in a postgraduate clinical residency program and highlight the intrinsic complexities, challenges and ultimately satisfaction related to cases of this nature.

Integrated versus non-integrated orbital implants for treating anophthalmic sockets.

BACKGROUND: Anophthalmia is the absence of one or both eyes, and it can be congenital (i.e. a birth defect) or acquired later in life. There are two main types of orbital implant: integrated, whereby the implant receives a blood supply from the body that allows for the integration of the prosthesis within the tissue; and non-integrated, where the implant remains separate. Despite the remarkable progress in anophthalmic socket reconstruction and in the development of various types of implants, there are still uncertainties about the real roles of integrated (hydroxyapatite (HA), porous polyethylene (PP), composites) and non-integrated (polymethylmethacrylate (PMMA)/acrylic and silicone) orbital implants in anophthalmic socket treatment. OBJECTIVES: To assess the effects of integrated versus non-integrated orbital implants for treating anophthalmic sockets. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 7), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to August 2016), Embase (January 1980 to August 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to August 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 8 August 2016. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs of integrated and non-integrated orbital implants for treating anophthalmic sockets. DATA COLLECTION AND ANALYSIS: Two authors independently selected relevant trials, assessed methodological quality and extracted data. MAIN RESULTS: We included three studies with a total of 284 participants (250 included in analysis). The studies were conducted in India, Iran and the Netherlands. The three studies were clinically heterogenous, comparing different materials and using different surgical techniques. None of the included studies used a peg (i.e. a fixing pin used to connect the implant to the prosthesis). In general the trials were poorly reported, and we judged them to be at unclear risk of bias.One trial compared HA using traditional enucleation versus alloplastic implantation using evisceration (N = 100). This trial was probably not masked. The second trial compared PP with scleral cap enucleation versus PMMA with either myoconjunctival or traditional enucleation (N = 150). Although participants were not masked, outcome assessors were. The last trial compared HA and acrylic using the enucleation technique (N = 34) but did not report comparative effectiveness data.In the trial comparing HA versus alloplastic implantation, there was no evidence of any difference between the two groups with respect to the proportion of successful procedures at one year (risk ratio (RR) 1.02, 95% confidence interval (CI) 0.95 to 1.09, N = 100, low-certainty evidence). People receiving HA had slightly worse horizontal implant mobility compared to the alloplastic group (mean difference (MD) -3.35 mm, 95% CI -4.08 to -2.62, very low-certainty evidence) and slightly worse vertical implant motility (MD -2.76 mm, 95% CI -3.45 to -2.07, very low-certainty evidence). As different techniques were used - enucleation versus evisceration - it is not clear whether these differences in implant motility can be attributed solely to the type of material. Investigators did not report adverse events.In the trial comparing PP versus PMMA, there was no evidence of any difference between the two groups with respect to the proportion of successful procedures at one year (RR 0.92, 95% CI 0.84 to 1.01, N = 150, low-certainty evidence). There was very low-certainty evidence of a difference in horizontal implant motility depending on whether PP was compared to PMMA with traditional enucleation (MD 1.96 mm, 95% CI 1.01 to 2.91) or PMMA with myoconjunctival enucleation (-0.57 mm, 95% CI -1.63 to 0.49). Similarly, for vertical implant motility, there was very low-certainty evidence of a difference in the comparison of PP to PMMA traditional (MD 3.12 mm 95% CI 2.36 to 3.88) but no evidence of a difference when comparing PP to PMMA myoconjunctival (MD -0.20 mm 95% CI -1.28 to 0.88). Four people in the PP group (total N = 50) experienced adverse events (i.e. exposures) compared to 6/100 in the PMMA groups (RR 17.82, 95% CI 0.98 to 324.67, N = 150, very low-certainty evidence).None of the studies reported socket sphere size, cosmetic effect or quality of life measures. AUTHORS' CONCLUSIONS: Current very low-certainty evidence from three small published randomised controlled trials did not provide sufficient evidence to assess the effect of integrated and non-integrated material orbital implants for treating anophthalmic sockets. This review underlines the need to conduct further well-designed trials in this field.

[Ocular prosthetics. Fitting, daily use and complications]. / Augenprothetische Versorgung. Anpassung, Handhabung und Komplikationen.

BACKGROUND: Ocular prosthetics make a decisive contribution to the functional, esthetic and psychosomatic rehabilitation of patients after ocular extirpation. OBJECTIVES: This article provides an overview of the fitting, daily care and complications of ocular prosthetics. METHODS: The study comprised a PubMed literature review and own clinical results. RESULTS: Ocular prosthetics made from cryolite glass or perspex can be manufactured and fitted 5-8 weeks after removal of the eye. During this period a conformer is placed within the conjunctival sac in order to prevent scar formation and shrinking of the socket. Artificial eyes can be worn continuously, only interrupted by a short but regular cleaning procedure. Artificial tears and lid hygiene improve the comfort of wearing. Glass prostheses have to be renewed every 1-2 years, while perspex prostheses need to be polished once a year. Complications, such as giant papillary conjunctivitis or blepharoconjunctivitis sicca are facilitated by poor fit, increased age and inappropriate care of the prosthetic device. In the case of socket shrinkage or anophthalmic socket syndrome, surgical interventions are needed to re-enable the use of an artificial eye. CONCLUSION: Adequate fitting, daily care of ocular prosthetics and therapeutic management of associated complications are mandatory for a durable functional, esthetic and psychosomatic rehabilitation after ocular extirpation.

Vision-Related Quality of Life and Appearance Concerns Are Associated with Anxiety and Depression after Eye Enucleation: A Cross-Sectional Study.

AIMS: To investigate the association of demographic, clinical and psychosocial variables with levels of anxiety and depression in participants wearing an ocular prosthesis after eye enucleation. METHODS: This cross-sectional study included 195 participants with an enucleated eye who were attending an ophthalmic clinic for prosthetic rehabilitation between July and November 2014. Demographic and clinical data, and self-reported feelings of shame, sadness and anger were collected. Participants also completed the National Eye Institute Visual Function Questionnaire, the Facial Appearance subscale of the Negative Physical Self Scale, and the Hospital Anxiety and Depression Scale. Regression models were used to identify the factors associated with anxiety and depression. RESULTS: The proportion of participants with clinical anxiety was 11.8% and clinical depression 13.8%. More anxiety and depression were associated with poorer vision-related quality of life and greater levels of appearance concerns. Younger age was related to greater levels of anxiety. Less educated participants and those feeling more angry about losing an eye are more prone to experience depression. Clinical variables were unrelated to anxiety or depression. CONCLUSIONS: Anxiety and depression are more prevalent in eye-enucleated patients than the general population, which brings up the issues of psychiatric support in these patients. Psychosocial rather than clinical characteristics were associated with anxiety and depression. Longitudinal studies need to be conducted to further elucidate the direction of causality before interventions to improve mood states are developed.

Digital capture, design, and manufacturing of a facial prosthesis: Clinical report on a pediatric patient.

A digitally captured, designed, and fabricated facial prosthesis is presented as an alternative to customary maxillofacial prosthodontics fabrication techniques, where a facial moulage and patient cooperation may be difficult.

Ocular rehabilitation following socket reconstruction with amniotic membrane transplantation with failed primary hydroxyapatite implant post enucleation.

There are several clinical situations that require enucleation in children, with retinoblastoma being the most common. Intra-orbital implants are routinely placed in children at the time of initial surgery to provide motility and cosmesis in addition to adequate orbital volume. Current practice employs intra-orbital implants made of nonporous silicone, hydroxyapatite, or porous polyethylene. Complications are usually minimal with these implants but they do occur. The purpose of this clinical report is to describe the rehabilitation of a pediatric patient with failed primary intra-orbital coralline hydroxyapatite implant post enucleation, who was successfully fitted with custom ocular prosthesis following secondary socket reconstruction with amniotic membrane transplantation after removal of infected implant.

Changing ocular prostheses in growing children: a 5-year follow-up clinical report.

Eye loss in children can be caused by trauma, glaucoma, or cancer, and may result in anxiety and depression. Recovery after eye loss involves a replacement with a custom-made eye prosthesis, but, as the patient ages, changes in the size and shape of the eye socket can result in a sunken appearance of the child's prosthetic eye. This article describes the fabrication of a custom-made eye and the necessity of changing ocular prostheses for a growing child, with a 5-year follow-up.

Prosthetic management with a scleral prosthesis: an 'eye on an eye'.

Eyes are an essential organ not only in terms of vision but also being an important component of facial expression. The loss of an eye has a crippling effect on the psychology of the patient. A natural eye is surgically removed by enucleation, evisceration or exenteration because of trauma, pathology or tumor. Treatment of such rehabilitation cases includes implant-retained and acrylic eye prostheses by a maxillofacial prosthodontist to restore the patient's quality of life. For economic reasons, a removable acrylic prosthesis is preferred over an implant-retained prosthesis. Here, we describe a case of a customized acrylic scleral shell prosthesis which showed excellent retention and esthetics.

Results of complex ultrasonic examination in different time after socket reconstruction using biomaterial "Alloplant" are presented. Modified technique of primary socket reconstruction showed good cosmetic result.

A multidisciplinary approach for management of postenucleation socket syndrome with dermis-fat graft and ocular prosthesis: a clinical report.

A contracted eye socket is a cosmetic blemish to the patient. It not only renders patients unable to wear an eye prosthesis, but also becomes a source of chronic discharge and irritation. Orbital implants allow for cosmesis and volume replacement of an enucleated or eviscerated eye. Alloplastic orbital implants are associated with potential complications, including exposure and extrusion. A dermis-fat graft offers the advantages of relative availability and an autologous nature. This article reports on a patient suffering from severe postenucleation socket syndrome after enucleation of the bulbus with postoperative irradiation of the orbit due to retinoblastoma and its subsequent management by a dermal-fat graft and ocular prosthesis. The purpose of this article is to emphasize the usefulness of dermal-fat grafting as a safe and stable orbital volume replacement following enucleation.

[Historical aspects of eye prosthetics].

The article is devoted to the problems of eye prosthetics that develops since ancient times till today. Indications for eye prosthesis and its role in rehabilitation of anophthalmic patients are determined. The process of glass prostheses production is described in details, technology is discussed and illustrated. This article is of great interest for opthalmologists and prosthetic technicians as it is proved that glass prostheses are more physiologic and have a number of advantages compared to plasticones.

Prosthetic rehabilitation of a patient with enucleated eye - a case report.

BACKGROUND: The loss of an eye has a crippling effect on the psychology of the patient, making rehabilitation process challenging for both doctor and patient. OBJECTIVE: To report a case of anophthalmic socket with prosthetic rehabilitation in a cost effective manner. CASE: A 32-year-old female presented with anophthalmic socket for prosthetic rehabilitation. A custom made ocular prosthesis was implanted successfully. CONCLUSION: The custom made ocular prosthesis is simple, affordable and can be carried out in a small clinical set-up and provides a superior natural appearance.

Rehabilitation after surgical treatment for retinoblastoma: ocular prosthesis for a 6-month-old child.

Maxillofacial prosthetic (MFP) rehabilitation can be especially challenging in a young, precooperative, or behaviorally compromised child presenting with an enucleated eye. Retinoblastoma is the most common intraocular malignancy in childhood and is one of the most common pediatric cancers. Treatment consists of enucleation (or removal of the entire globe) followed by placement of orbital implants. Unrestored anopthalmic sockets exhibit growth retardation and can lead to facial disfigurement. This report describes the challenges faced during rehabilitation of a 6-month-old girl with an anophthalmic socket due to enucleation for retinoblastoma. The objective of the MFP team was to provide a custom-built, acrylic ocular prosthesis in as comfortable and atraumatic manner as possible. The case was a success and underscores the value of a multidisciplinary dental approach for the treatment of children with very special needs.

[Profile of patients with anophthalmic cavity: study at Faculdade de Medicina de Botucatu - UNESP]. / Perfil dos portadores de cavidade anoftálmica: estudo na Faculdade de Medicina de Botucatu - UNESP.

PURPOSE: To evaluate the profile of anophthalmic cavity carriers and patients' evolution with the employed treatments. METHODS: Retrospective study carried out at Faculdade de Medicina de Botucatu, to evaluate the profile and the evolution of patients with anophthalmic cavity treated in our service. Data were evaluated according to the frequency of occurrence and analysis of association. RESULTS: Anophthalmic cavity was more frequently observed in young males, workers in activities carried on with their hands. Trauma and phthisis bulbi were the most frequent causes, with differences according to age and gender. The complications were high (57.1% of cases), the majority occurred belatedly. CONCLUSIONS: Trauma is still an important cause of loss of the eye. The complications during the follow-up of the patient are frequent, occurring in general, very late, which reinforces the need for periodic and prolonged monitoring of patients with anophthalmic cavity.

Enxerto dermoadiposo em cavidades anoftálmicas secundárias: estudo retrospectivo e revisão da literatura / Dermofat graft in secondary anophthalmic socket: a retrospective study and literature review

OBJETIVO: Avaliar o uso do enxerto dermoadiposo no tratamento da cavidade anoftálmica. MÉTODOS: Estudo retrospectivo, do qual participaram 28 portadores de cavidade anoftálmica secundária, tratados com enxerto dermoadiposo. Os dados avaliados foram: idade, sexo, motivo da primeira cirurgia, tipo de cavidade, razão da opção pelo enxerto dermoadiposo, resultados e complicações. Os dados foram analisados segundo a frequência de ocorrência. RESULTADOS: dos 28 pacientes analisados, 19 (67,8 por cento) eram do sexo masculino, 46,4 por cento deles apresentando de 40 a 60 anos de idade. A principal causa da perda do olho foi o trauma (7 casos - 25,0 por cento). A cavidade onde mais se empregou o enxerto dermoadiposo foi a do tipo III (32,1 por cento). Como primeira cirurgia, a evisceração havia sido realizada em 13 casos, a enucleação em 11 e o enxerto de pele em dois pacientes e em outros dois, não havia informação sobre a primeira cirurgia a que haviam sido submetidos. A opção pelo enxerto dermoadiposo foi feita com a finalidade de repor volume na cavidade e, ao mesmo tempo, conseguir maior superfície anterior da cavidade, já que a maioria possuía cavidades contraídas. A maioria dos pacientes (53,6 por cento) não apresentou complicações, tendo sido a necrose do enxerto a complicação mais observada (32,1 por cento). O resultado final da cirurgia foi considerado bom em 71,4 por cento dos pacientes e ruim em 7,1 por cento. CONCLUSÃO: O enxerto dermoadiposo é uma técnica cirúrgica simples e de bons resultados para reposição de volume em cavidades anoftálmicas. Os autores estimulam o ensino da mesma nos serviços de treinamento de jovens cirurgiões.

PURPOSE: To evaluate the dermofat graft in the anophthalmic socket treatment. METHODS: A retrospective study including 28 anophthalmic cavity carriers treated with dermofat graft was carried out. The patients were analyzed according to age, sex, socket contraction degree, first surgery performed, reason for graft choice, procedure´s results and complications. The data were analyzed according to the frequency of occurrence. RESULTS: Nineteen (67.8 percent) of the 28 analyzed patients were male. According to age the majority of patients were between 40 to 60 years old (13 patients - 46.4 percent) and the most common cause of eyeball loss was trauma (seven cases - 25 percent). Anophthalmic socket type III was the most frequently observed (32.1 percent). The evisceration was the first procedure in 13 cases, enucleation in 11 and skin graft was done in two patients. Two patients came to the service after evisceration and did not provide any information about the first surgery. The choice to use the dermofat graft was to replace volume at the socket of 12 patients (42.8 percent). Most of the patients (53.6 percent) had no complications and graft necrosis was the problem most frequently observed (32.1 percent). The surgery was considered good in 71.4 percent and not good in only 7.1 percent. CONCLUSION: the dermofat graft is an efficient and easy technique to reconstruct the anophthalmic cavity. The authors suggest this procedure must be introduced in the medical training services since it provide good results.
