RESUMO

A comprehensive questionnaire with 43 questions was designed to evaluate quality of life, based on rehabilitation with a facial prosthesis. Each patient's psychological situation was assessed using the validated questionnaire and associated scales. Different patient groups were compared with each other in terms of questionnaire scores and general data. In total, 76 patients with a prosthesis of the orbit, nose, or ear, or a combination thereof, were included. There was a highly significant difference in overall satisfaction with defect reconstruction via a prosthesis of the ear compared with the orbit and nose (F(3) = 6.511, p = 0.001). Patients with congenital defects showed a significantly higher level of general satisfaction compared with patients with acquired defects (F(2) = 5.795, p = 0.001). Patients who returned to work were significantly more satisfied with their quality of life (T(57) = 2.626, p = 0.011). With regard to improvements to the state-of-the-art prostheses, the majority of patients suggested better retention, more durable colors, make-up possibilities, less noticeable margins, softer materials, and a movable orbital prosthesis. Within the limitations of the study it seems that facial epitheses improved mental wellbeing and increased quality of life among patients with facial defects. Multiple factors, such as type of facial defect, location of residence, and education can have a potential influence on the quality of life of affected patients. However, further studies are needed, since the psychological and social challenges remain.

RESUMO

Purpose: To compare different assessment methods for peri-implant inflammation to evaluate potential risk factors and to generate a comprehensive algorithm for clinical staging, treatment, and evaluation of success in periorbital implants. Materials and Methods: In this hospital-based cross-sectional study, 111 periorbital implants in 40 patients with orbital defects after exenteration were clinically analyzed. Skin reaction according to Holgers (SRH), probing depth (PD) , and sulcus fluid flow rate (SFFR), as well as patient-specific data, such as age, sex, smoking and irradiation status, cleaning agent and frequency, defect etiology, implant system, implant location, time span since implantation, and type of retention, were assessed and statistically analyzed via mixed-model calculations. Success was defined as the absence of necessary invasive or antibiotic treatment. Results: A total of 62 implants (55.9%) had been placed in male patients and 49 implants (44.1%) in female patients. There were 18 patients (52 implants, 46.8%) who had received radiotherapy. Mean inflammation levels were low. PD and SFFR were highly correlated, whereby PD increased significantly with time after implantation. SRH ≥ 2 was correlated significantly with higher PD and SFFR values. While 80% of the implants did not require invasive or antibiotic treatment, 45% of the patients presented at least one affected implant. The data gathered allowed for the definition of a staging and treatment algorithm for peri-implantitis in periorbital implants. No patient-specific factors showed a significant impact on peri-implant inflammation. Conclusion: Periorbital implant restorations with magnetic abutments are a safe treatment option for orbital defects. PD and SRH were proven to be valuable quick assessment tools and should be complemented by SFFR, if inconclusive. The established parameters for the staging of peri-implant tissue health and clinical success can serve as a viable tool for reliable and comparable assessment in clinical and scientific settings. Further studies are necessary to assess the suggested treatment algorithm.

RESUMO

PURPOSE: Reliable application of endosseous implants for prosthetic facial reconstruction depends on the bone volume available at the defect site. Regarding the orbit, sufficient bone presentation in the medial superior orbital rim is limited due to the frontal sinus. The aim of this article is to report for the first time on the augmentation of the frontal sinus for gaining bone volume for supraorbital implant placement. MATERIALS AND METHODS: Between 2007 and 2014, five patients with orbital exenteration were treated by frontal sinus augmentation using autogenous cancellous bone graft from the ilium. Extraoral implants for prosthetic orbit reconstruction were placed 4-7 months later. In advance, cadaver surgery was performed to prove the feasibility of the method. Surgical technique is described, and intraoperative images are provided. RESULTS: The frontal sinus was successfully augmented in all five patients. No major complications related to the procedure were observed. A total of nine orbital implants were inserted in the augmented bone, thereof one sleeping implant. Six implants were restored prosthetically, two implants were lost at exposure. The observation period ranged from 6 to 97 months (mean: 52.8 months). Mean time for patient rehabilitation was 13 months. High patient satisfaction was achieved with the implant-retained orbital prosthesis. CONCLUSION: The augmentation of the frontal sinus allows implant placement by providing sufficient bone volume in the medial supraorbital rim. Considering the surgical success of this method and patient satisfaction, this new approach is concluded to be a viable option in a unique subset of patients.

RESUMO

BACKGROUND: Application of endosseous implants in prosthetic craniofacial reconstruction represents a secure and reliable method and is a well-established surgical procedure. In areas of low bone presentation, standardized plate-like titanium implants are available. For allowing a congruent fitting to the recipient site, these contemporary implants have to be manually adapted--implicating drawbacks in terms of time consumption, technical complexity, and insufficient functional outcome. Owing to these limitations, a custom-made patient-specific implant is introduced based on Digital Imaging and Communications in Medicine (DICOM) data and designed for optimal prosthetic reconstruction. METHODS: For the first time, the application of a prefabricated patient-specific implant for retaining a craniofacial prosthesis is described. In a 64-year-old man with partial nasal defect standardized plate-like implants failed because of compromised bone quality due to Osler disease. To realize an implant-retained prosthetic reconstruction, a patient-specific implant was fabricated based on computer-aided design and computer-aided manufacturing (CAD/CAM) technology. This technique allows for considering the implant's ideal geometry as well as its correct placement of the required magnetic abutments. Furthermore, the surface of the implant can be designed for optimal hygienic conditions. RESULTS: The patient-specific implant was successfully inserted in a time effective operating procedure. Follow-up at 6 months showed an excellent functional and aesthetic outcome. CONCLUSIONS: Application of prefabricated patient-specific implants offers prospectively an ideal tool for retaining craniofacial prostheses and should be considered a viable option in standard cases, but obligatory in anatomically demanding defects.

RESUMO

Optimum functional and aesthetic facial reconstruction is still a challenge in patients who suffer from inborn or acquired facial deformity. It is known that functional and aesthetic impairment can result in significant psychosocial strain, leading to the social isolation of patients who are affected by major facial deformities. Microvascular techniques and increasing experience in facial transplantation certainly contribute to better restorative outcomes. However, these technologies also have some drawbacks, limitations and unsolved problems. Extensive facial defects which include several aesthetic units and dentition can be restored by combining dental prostheses and anaplastology, thus providing an adequate functional and aesthetic outcome in selected patients without the drawbacks of major surgical procedures. Referring to some representative patient cases, it is shown how extreme facial disfigurement after oncological surgery can be palliated by combining intraoral dentures with extraoral facial prostheses using individualized treatment and without the need for major reconstructive surgery.
