Maxillofacial rehabilitation of nasal defect with nasal prosthesis using donor method: A case report.

Maxillofacial prosthetics is the branch of prosthodontics which involves rehabilitation of the defects in the maxillofacial region involving the hard and soft tissue with the prosthesis. Facial defects that occur in the midfacial regions are commonly due to trauma and neoplasms like basal cell carcinoma which involves the nose. Reconstruction of the nose is an important esthetic challenge due to its esthetic and retention problems. This article emphasis rehabilitation of the nasal defect of a patient with nasal prosthesis using donor method.

Quality of life after nasal cancer resection - surgical versus prosthetic rehabilitation.

BACKGROUND: Nose reconstruction following resection of nasal carcinomas is controversial. The objective of this study is to investigate the effect of surgical reconstruction versus prosthetic rehabilitation on patient quality of life (QOL). DESIGN: This was a monocentric prospective study of patients diagnosed with nasal carcinoma from 2003 to 2013. QOL was evaluated using two organ-specific questionnaires (Rhinoplasty Outcome Evaluation [ROE] and the Functional Rhinoplasty Outcome Inventory-17 [FROI-17]) and a generic questionnaire, the Short-Form 36 Health Survey (SF-36). MATERIAL AND METHODS: Sixty-four patients were included. Patients completed the ROE, FROI-17, and SF-36 questionnaires after nasal reconstruction. Questionnaires were completed by 62.8% of the 51 alive patients. RESULTS: Recurrence-free survival (RFS) was 89.9%, disease-specific survival was 94.5%, and overall survival was 75.5% after five years according to the Kaplan-Meier method. Considering initial tumor stage, early stage patients had a significantly higher self-confidence score in FROI-17 subgroup analysis. In contrast, advanced stage patients showed a significantly higher score for social functioning in SF-36. Prosthetically fitted patients scored highly on the ROE questionnaire showing a high degree of aesthetic satisfaction. Surgically reconstructed patients showed a high degree of self-confidence on the FROI-17 questionnaire. However, the organ-specific ROE and FROI-17 scores were not significantly different between patients who received surgical reconstruction and prosthetic rehabilitation after oncological resection. When comparing the rehabilitation method as a function of tumor stage, there was significantly better score for physical functioning in early stage surgically reconstructed patients in the SF-36, but no significant differences in organ-specific QOL. CONCLUSION: Surgical reconstruction and prosthetic rehabilitation after nasal cancer resection have the same effect on organ- and non-organ-specific QOL.

Avaliação da modificação da técnica de reconstrução das cartilagens alares de Max Pereira no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre / Evaluation of Max Pereira alar reconstruction technique modification in the total nasal reconstruction protocol of the Hospital of Clinics of Porto Alegre

Introdução: A reconstrução nasal é a mais antiga das cirurgias plásticas. A anatomia nasal é complexa e necessita de uma associação de técnicas para a restauração da função e estética nasal adequada. Pereira et al. descreveram uma técnica que possibilita a reconstrução nasal total da cartilagem alar, com o uso de um enxerto da cartilagem auricular, com mínima deformidade auricular secundária à retirada do enxerto. O objetivo deste trabalho é apresentar uma modificação da técnica acima descrita, que possibilita reconstruir mais uma região anatômica do nariz, sem aumentar a morbidade, realizada por Collares et al., e a sua inserção no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre. Métodos: Foi realizado um estudo retrospectivo. Avaliou-se a inserção da modificação da técnica em 10 pacientes que realizaram reconstrução nasal total. Resultados: Após a análise dos 10 casos, utilizando a modificação da técnica inserida no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre, encontramos uma melhoria da forma do nariz, a válvula nasal interna com preservação da função e sem sequelas secundárias à retirada do enxerto auricular. Conclusão: Nesta série de casos, a modificação da técnica de Max Pereira resultou em tratamento estético funcional adequado quando implementada no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre, sem aumentar a morbidade na área doadora.

Introduction: Nasal reconstruction is the oldest plastic surgery technique. The nasal anatomy is complex and requires an association of techniques for the restoration of function and adequate nasal esthetics. Pereira et al. described a technique that allows total nasal reconstruction of the alar cartilage through the use of an auricular cartilage graft, with minimal deformity secondary to the donor site. The objective of the present study is to present a modification, by Collares et al., of the technique described above, which allows the reconstruction of another anatomical region of the nose without increasing morbidity, and its insertion into the total nasal reconstruction protocol of Hospital de Clínicas of Porto Alegre. Methods: A retrospective study was conducted. We evaluated technique modification in 10 patients who underwent total nasal reconstructions. Results: After examining the 10 patients who were treated with the modified total nasal reconstruction protocol at the Hospital de Clínicas of Porto Alegre, we observed an improvement in the nose shape and internal nasal valve with preservation of function, without sequelae secondary to auricular graft removal. Conclusion: In this case series, the modification of the Max Pereira technique resulted in adequate aestheticfunctional treatment when implemented in the total nasal reconstruction protocol of the Hospital de Clínicas of Porto Alegre, without increasing the morbidity in the donor area.

Virtual Treatment Planning for Implant-Retained Nasal Prosthesis: A Clinical Report.

Osseointegrated craniofacial implants have improved retention and patients' perceptions of implant-retained nasal prostheses; however, the determination of the available bone sites for implant placement post-rhinectomy is difficult. This case report describes the use of cone beam computed tomography scanning and computer-assisted virtual planning in conjunction with digital photographs for rehabilitation of a facial defect with an implant-retained silicon nasal prosthesis. Two implants were planned in the anatomical area with adequate bone volume to achieve favorable cosmetic outcomes and accessibility for hygiene maintenance. The implant-retained nasal prosthesis resulted in a meaningful improvement in the esthetics without the need for plastic surgery. In such cases, the post-rhinectomy reconstruction surgery should be limited to preparation of the surgical defect area for an implant-retained prosthesis. Silicone prostheses are reliable alternatives to surgery and should be considered in selected cases.

Rehabilitación protésica de un paciente con defecto nasal / Prosthetics rehabilitation of a patient with nasal defect

Se describe el caso clínico de un paciente de 84 años de edad, a quien se le realizó exéresis total del órgano nasal desde hacía 5 años aproximadamente en el Hospital Oncológico Conrado Benítez de Santiago de Cuba, a causa de un carcinoma epidermoide del apéndice nasal, por lo cual fue remitido al Centro de Rehabilitación Protésica Bucomaxilofacial de esta provincia para ser rehabilitado. Al examen físico extrabucal se observó ausencia total de la nariz, que simulaba una facies leonina, con bordes cicatrizados y bien definidos. La mayor preocupación del paciente era ocultar su defecto, de manera que se le realizó una prótesis nasal de silicona para mejorar su estética y funcionalidad

The case report of an 84 years patient is described, to whom a total removal of the nasal organ was carried out about 5 years ago-at Conrado Benítez Cancer Hospital in Santiago de Cuba - due to an epidermoid carcinoma of the nasal appendix, reason why he was referred to the Oralmaxillofacial Prosthetics Rehabilitation Center of this province to be rehabilitated. A total absence of the nose was observed in the extraoral physical examination that simulated a leonine facies, with well defined healed borders. The patient's biggest concern was to hide his defect, so a nasal silicone prosthesis was placed to improve his aesthetics and functionality

Orofacial rehabilitation with zygomatic implants: CAD-CAM bar and magnets for patients with nasal cancer after rhinectomy and partial maxillectomy.

Nasal carcinoma extending into the premaxilla requires radical surgical excision including rhinectomy and partial maxillectomy. Rehabilitation is complex and involves the use of removable prostheses. Three patients treated with zygomatic implants and custom-milled bars to retain an obturator and nasal prosthesis are presented.

Implant-supported and magnet-retained oral-nasal combination prosthesis in a patient with a total rhinectomy and partial maxillectomy due to cancer: A clinical report.

This clinical report describes the fabrication of an implant-supported and magnet-retained combination oral-nasal prosthesis for a patient with a midline midfacial defect. The patient had undergone a total rhinectomy and partial maxillectomy as part of his cancer treatment. The nasal prosthesis was retained on the face by a magnet attached to the implant-supported maxillary denture, resulting in improved appearance and the recovery of speech, mastication, and swallowing functions.

Anaplastology in times of facial transplantation: Still a reasonable treatment option?

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.

Single-stage osseointegrated implants for nasal prosthodontic rehabilitation: A clinical report.

Malignant tumors in the nasal region may be treated by means of invasive surgical procedures, with large facial losses. Nasal prostheses, retained by osseointegrated facial implants, instead of plastic surgery, will, in most patients, offer good biomechanical and cosmetic results. This clinical report describes the prosthetic rehabilitation of a patient with nasal cancer who had the entire nasal vestibule removed in a single-stage surgical procedure in order to shorten the rehabilitation time. The nasal prosthesis was built on a 3-magnet bar and was made of platinum silicone with intrinsic pigmentation, thereby restoring the patient's appearance and self-esteem. The authors concluded that single-stage implants may reduce the rehabilitation time to as little as 1 month, and the correct use of materials and techniques may significantly improve the nasal prosthesis.

Rehabilitation of an extraoral and intraoral defect complicated with microstomia. A study case.

A 72-year-old man was referred from the surgery department for rehabilitation following surgical resection of Basaloid carcinoma. The first surgical intervention involved the anterior palatal region and was restored with a simple obturator. Two years later further surgery was undertaken to excise a recurrent tumor in the nose and part of the cheek. This resulted in an exposed nasal cavity and maxillary sinus. In addition, there was a small oral aperture composed of thin tissue that stretched to its maximum due to scar formation. The defect was restored with a full thickness skin flap but it subsequently broke down leaving the midface exposed with limited mouth opening due to tissue contraction and scar formation after the flap operation. The defect was rehabilitated with Co-Cr obturator intraorally and a silicone nose retained to the naso-palatal extension of the obturator by a magnet extraorally. This resulted in practically good retention, placement, and adaptation of the two parts of the prosthesis.

Rhinectomy for the management of nasal malignancies.

BACKGROUND: Tumours of nasal skin or mucosa are common, and can usually be treated with limited surgical excision or radiotherapy. This paper highlights a subset of high risk tumours which require rhinectomy for complete oncological clearance. METHOD: Retrospective case note review of 14 patients undergoing rhinectomy for nasal tumours. Clinical and histological findings, treatment and outcome are reviewed and discussed. RESULTS: Forty-three per cent of patients had recurrent disease and underwent rhinectomy as a salvage procedure following previous surgery or radiotherapy. Most tumours (79 per cent) were basal cell carcinoma or squamous cell carcinoma. After a mean follow up of 30.1 months (range, zero to 96 months), seven patients (50 per cent) were alive and disease-free. Reconstruction was most commonly with a prosthesis. CONCLUSION: Rhinectomy is an oncologically sound procedure for the management of high risk nasal malignancies. Prosthetic rehabilitation can be an excellent alternative to surgery, particularly in those patients unsuitable for major reconstruction.

Missing facial parts computed by a morphable model and transferred directly to a polyamide laser-sintered prosthesis: an innovation study.

Mirroring of missing facial parts and rapid prototyping of templates have become widely used in the manufacture of prostheses. However, mirroring is not applicable for central facial defects, and the manufacture of a template still requires labour-intensive transformation into the final facial prosthesis. We have explored innovative techniques to meet these remaining challenges. We used a morphable model of a face for the reconstruction of missing facial parts that did not have mirror images, and skin-coloured polyamide laser sintering for direct manufacture of the prosthesis. From the knowledge gleaned from a data set of 200 coloured, three-dimensional scans, we generated a missing nose that was statistically compatible with the remaining parts of the patient's face. The planned prosthesis was manufactured directly from biocompatible skin-coloured polyamide powder by selective laser sintering, and the prosthesis planning system produced a normal-looking reconstruction. The polyamide will need adjustable colouring, and we must be able to combine it with a self-curing resin to fulfil the requirements of realistic permanent use.

Functional and aesthetic reconstruction of extensive oral ablative defects using temporalis muscle flap: a case report and a sort review.

PURPOSE: Temporalis muscle flap (TMF) provides a reliable solution in reconstruction of extensive intraoral ablative defects, providing a valuable alternative to more complex and extensive reconstructive procedures, combining excellent functional and aesthetic rehabilitation with minimal complications. In this article is described in detail the TMF surgical technique with attention to specific methods useful for preventing facial nerve injury and donor-site deformity. MATERIALS AND METHODS: It is presented the case of a patient with malignant tumour in the region of the upper jaw, palate and inferior half of the nasal cavity, who underwent extensive surgical excision and the resultant defect was successfully reconstructed with TMF. RESULTS: The reconstructive procedure resulted in excellent immediate and long-term functional (aspiration, feeding and speech) and aesthetic results. During the 5-year follow-up period no complications associated with the flap or the temporal implant, used for donor-site reconstruction were encountered and no local recurrence or tumour metastasis was observed. CONCLUSION: The TMF is a reliable, technically easy and anatomically sound technique, which combines excellent aesthetic and functional results with minimal complications, if performed correctly.

Maxillofacial rehabilitation of a microstomic patient after resection of nose, lip, and maxilla.

Few published reports have addressed the issues related to upper lip reconstruction. The present clinical report describes the maxillofacial rehabilitation of an edentulous patient who had been diagnosed with squamous cell carcinoma of the nasal septum and contiguous structures. The patient underwent total rhinectomy, anterior maxillectomy, and maxillary lip resection. Her maxillary lip was reconstructed with a bilateral cheek advancement flap, which allowed primary closure of the lip and aided in maintaining function of the orbicularis oris muscle. Microstomia was anticipated and was a consequence of this procedure. During primary resection, and before chemoradiotherapy, dental implants were successfully placed in the maxilla. These implants helped to retain a maxillary obturator prosthesis, which, in turn, helped to retain a silicone nasal prosthesis that restored the nasal defect. An intranasal acrylic resin framework with magnets aided in connecting the extraoral prosthesis with the intraoral prosthesis. The surgical and prosthodontic advantages of a cheek advancement flap and the treatment challenges in a microstomic patient are discussed.

Implant-retained nasal prosthesis for reconstruction of large rhinectomy defects: the Salisbury experience.

The authors report their experience with 34 patients who had large full thickness nasal defects reconstructed with an implant-retained prosthesis. Their technique of modifying post-rhinectomy defects is described and factors influencing implant success are evaluated. 111 implants were placed to retain a nasal prosthesis. Age, sex and tumour histology did not affect the outcome. Smoking, extent of rhinectomy, use of radiotherapy (pre- and post-implant), hyperbaric oxygen, length and location of the implant and type of retention (bar/magnets) influenced implant success. The overall success rate was 89% (99/111); 94% in patients who did not receive radiotherapy and 86% in those who did. The prosthesis was in place in all patients (100%) at the time of last follow up. Post-rhinectomy defect modification enables adequate access for safe placement of long implants with good primary stability and helps the maintenance of good hygiene (further enhanced by the use of skin grafts). The authors think implant-retained prosthesis is a reliable option for reconstructing large full thickness rhinectomy defects. They suggest their technique of modifying the defect, use of long implants and magnets for retention is responsible for the high success rate of implants used to retain a nasal prosthesis.

Retrospective analysis of titanium plate-retained prostheses placed after total rhinectomy.

PURPOSE: To report the use of a new platelike system (Titanium Epiplating System, Medicon, Tuttlingen, Germany) for rehabilitation of patients after total rhinectomy. MATERIALS AND METHODS: This retrospective study was conducted on all patients treated between August 2001 and July 2006 with total or subtotal rhinectomy. The clinical outcomes and satisfaction of patients receiving nasal prostheses were evaluated, and the success rate of the subperiosteal implants was determined. Quality of life (QOL) was evaluated with a standardized questionnaire. Patients who had experience with different retention methods responded to a five-point scale evaluating their current satisfaction. RESULTS: Eleven patients (four women and seven men) received nasal prostheses. The mean age was 63 +/- 12 years (range, 43 to 84 years). Nine patients were fitted with subperiosteal microplates and followed for a mean of 35 months. Two patients had subtotal rhinectomy and did not receive implants. In four patients immediate implant placement (concurrent with tumor resection) was performed; the other five patients received implants later. The implant success rate was 82%. There was no early implant loss, although one patient lost his implants after 3 years and another patient lost one implant after 1.5 years. QOL scores demonstrated high acceptance of implant fixed retention in comparison with other retention methods (P = .001). CONCLUSIONS: Implantation of anatomically prefabricated titanium plates has a high success rate in the nasal area, although late implant loss may occur. Patient perceptions of QOL show improvement when prostheses are retained by subperiosteal implants.

A fiber-reinforced composite prosthesis restoring a lateral midfacial defect: a clinical report.

This clinical report describes the use of a glass fiber-reinforced composite (FRC) substructure to reinforce the silicone elastomer of a large facial prosthesis. The FRC substructure was shaped into a framework and embedded into the silicone elastomer to form a reinforced facial prosthesis. The prosthesis is designed to overcome the disadvantages associated with traditionally fabricated prostheses; namely, delamination of the silicone of the acrylic base, poor marginal adaptation over time, and poor simulation of facial expressions.
