Orbital exenteration for sinonasal malignancies: indications, rehabilitation and oncologic outcomes.

PURPOSE OF REVIEW: Review the recent literature regarding the management of orbital invasion in sinonasal malignant tumors. RECENT FINDINGS: There is a recent trend in preserving the orbit in cases of minimal invasion of periosteum and limited periorbit involvement, as well as in presence of good response to neoadjuvant chemotherapy, mainly in squamous cell carcinoma and neuroendocrine histologies. SUMMARY: The decision about orbital exenteration in cases of sinonasal malignancies is facilitated if the patient already has clear clinical signs of intraconal invasion such as visual loss, restriction of ocular mobility or infiltration of the eyeglobe. However, in borderline situations, confirmation of orbital involvement should be performed intraoperatively. In selected cases with minimal orbital invasion without functional compromise, orbit sparing surgery can be done with acceptable oncological outcomes.

Prosthetic Rehabilitation of a Complex Maxillofacial Defect as an Alternative to Surgical Reconstruction: A Case History Report.

Free tissue transfers are used to restore maxillofacial resected tissues during tumor ablative surgery. The maxillofacial prosthodontist remains an integral member of the therapeutic team, since conventional retained facial prostheses are in certain cases the most practical, trouble-free, cost-efficient, and successful means of rehabilitation.

Rehabilitation of orbital defect with silicone orbital prosthesis retained by dental implants.

Orbital defects can result from cancer, birth anomalies, or trauma leading to an onslaught of problems in the function and psyche of the patient. These defects are restored by surgical reconstruction and followed by placement of orbital prosthesis for cosmetic makeup. The use of dental implants in retaining orbital prosthesis improves patient acceptance of the prosthesis owing to better retention and stability than conventional adhesive retained prosthesis. This case report describes a custom-made magnetic retentive assembly anchored by a dental implant which offers the orbital prosthesis the simplicity of self-alignment and ease of use.

Closed-eye orbital prosthesis: a clinical report.

One of the most challenging prostheses to fabricate is an acceptable orbital prosthesis. Successful reconstruction of the complex missing tissues, the globe, muscle, skin, and bony elements requires time and high levels of practical skill. A good match to the contralateral nondefect side will help mask the underlying defect and give the patient confidence to return to normal, routine life. The contralateral eye opening will commonly dictate the eye opening of such a prosthesis, but because of the expressive nature of the eye and its high levels of mobility, this can be difficult to achieve. This clinical report presents a patient who had an extended orbital exenteration and right maxillectomy to remove a maxillary squamous cell carcinoma. An alternative approach to constructing an orbital prosthesis was undertaken with the eye closed. Compared to the normal method of fabrication, this process was less complex and quicker, made the prosthesis less "staring," camouflaged the defect, and reduced the detection of the prosthesis because of movements in the remaining eye. The patient engaged in his routine daily life, which reinforced his self-esteem, confidence, and reintegration into the community.

Prosthetic rehabilitation after orbital exenteration: a case series.

Orbital exenteration is executed by the ophthalmic surgeon to treat various neoplasms or non-malignant diseases. But it leads to several functional, esthetic and psychological problems for the patients. Orbital prosthesis is a good alternative for cosmetic and psychological rehabilitation, if reconstructive surgery is not possible or not desired by the patient. In the following article, different materials and retentive aids for fabrication of an orbital prosthesis given in the literature along with few novel methods have been discussed for four patients who underwent orbital exenteration. Factors that an ophthalmic surgeon should consider during surgery, which may later on help the prosthodontist to obtain good cosmetic results, are also discussed briefly. Remarkable results can be obtained if both work as a team for one common goal i.e. improvement of quality of life of the patient after orbital exenteration.

Orbital exenteration and periorbital skin cancers.

PURPOSE: Orbital exenteration is a disfiguring surgical procedure that requires thoughtful reconstruction. PATIENTS AND METHODS: We analyzed all cases of orbital exenteration done in our department since 1998. RESULTS: A total of 26 patients had undergone surgery during our study period, and 27 exenterations have been conducted since 1998. The reconstruction was performed in 20 patients using an ipsilateral temporal muscle flap. One patient underwent reconstruction using a temporalis fascia flap and 6 using free flaps. A total of 11 patients received postoperative radiotherapy. Data collection revealed 6 patients with an ocular prosthesis. The prosthesis had either been glued or mounted onto glasses. CONCLUSIONS: Analyzing our results and the published data, we found that the reconstruction mode influences prosthetic rehabilitation. Thus, we have identified 2 categories. In the first category, postoperative radiotherapy will be required and coverage with a flap will be needed. In the second category, postoperative radiotherapy is not indicated and thus the healing time might be extended in favor of more space for better retention of the prosthetic rehabilitation.

Vacuum form sheet as a guide for fabrication of orbital prosthesis.

Rehabilitation with an orbital prosthesis is done when surgical reconstruction is not possible or affordable in patients with orbital exenteration. Fabrication of orbital prosthesis requires precision in placement of the ocular portion of the prosthesis on the facial moulage. This method describes the use of a vacuum formed sheet for making an orbital template that acts as a guide for achieving optimum orientation of the ocular portion of the prosthesis.

A unique method of retaining orbital prosthesis with attachment systems - a clinical report.

Diminution of the orbital contents post-surgical removal of a malignant tumor can have a severe psychological impact on the patient in terms of function and esthetics. Therefore, esthetic remedy should be planned subsequently, since tumor obliteration precedes cosmetic concern. A convenient option for successful rehabilitation in such patients is a simple, user-friendly, removable orbital prosthesis. Retention of the prosthesis is one of the key factors for the successful rehabilitation. Spectacle frame, conformers, adhesives, osseointegrated implants, magnets or buttons have been used to impart retention to the prosthesis. The use of semi precision attachments in maxillofacial prostheses is limited to the osseointegrated prostheses. This case report describes a conventional spectacle frame technique, to retain the silicone orbital prosthesis using two different types of stud attachments viz., dalla bona and O-ring attachment systems.

A new method for fabricating orbital prosthesis with a CAD/CAM negative mold.

The challenge of fabricating an orbital prosthesis is how to position the iris and pupil properly. Computer simulation can be a more effective and simpler approach to measuring and evaluating these features than the conventional method. However, transferring the optimal position of the iris determined in the virtual design procedure to the real definitive prosthesis can be difficult. The purpose of this article is to demonstrate a method of fabricating an orbital prosthesis with a negative mold designed and produced by a computer-aided design and computer-aided manufacturing technique. With this method, the iris can be designed in the most favorable position, and this position can be transferred to the silicone prosthesis correctly.

Anaplastology: changing appearances/changing lives.

This is a synopsis of the presentation delivered at the Society of Otorhinolaryngology and Head-Neck Nurses' Annual Congress and Nursing Symposium, September 11, 2012 in Washington, DC. We all have imperfections in our faces and bodies that we would like to change. Consider, though, the cancer patient or the trauma victim who must deal with a facial disfigurement that completely changes their appearance, and often, their ability to function normally. Anaplastology, which combines art and science through creativity and functionality, can make monumental improvements in the quality of a person's life by giving acceptable appearance back to the patient. Custom-made appliances and prosthetic creations can bring hope and confidence back to the patient. Individualized adaptations can make the prosthetic a true work of art. Nurses work closely with patients who are benefitting from this creative process. Arriving at a successful and pleasing outcome is extremely satisfying for the entire team, the patient and family.

Use of a stud attachment to retain a silicone orbital prosthesis: a clinical report.

Orbital defects with total loss of eyelids and eyeball cannot be satisfactorily repaired by reconstructive surgery. Prosthetic replacement is the treatment of choice owing to its acceptable lifelike appearance. The use of semiprecision attachments in maxillofacial prostheses is limited to osseointegrated prostheses. Therefore, this article describes a conventional glasses frame technique, to retain the silicone orbital prosthesis using a Dalla Bona stud attachment.

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.

[Orbital exenteration. Algorithm for therapy and rehabilitation]. / Orbitale Exenteration. Therapiealgorithmus und Rehabilitation.

Various procedures are available for orbital exenteration, mostly for neoplastic disorders, as well as for reconstructive surgery. Within the context of postoperative care prosthetic rehabilitation plays an important role. The specific form of planned epithetic replacement must already be considered in the design of the surgical procedure.

A modified technique for retention of orbital prosthesis.

An orbital defect (congenital or acquired) causes severe facial asymmetry and disfigurement, which results in psychological and social disturbances to the patient. It becomes a challenging task for a maxillofacial prosthodontist to fabricate a prosthesis that replicates the healthy side of the face. Success of the prosthesis depends primarily on satisfactory retention of the same. This clinical report illustrates rehabilitation of a patient with an orbital defect by fabricating a hollow orbital prosthesis, utilizing anatomical undercuts for retention using an acrylic resin template relined by a resilient denture liner.
