RESUMEN
Introdução: A ressecção cirúrgica de tumores em região de cabeça e pescoço é um tratamento eficaz, mas que implica em significativa desfiguração facial dependendo da localização da lesão. Aqueles pacientes considerados curados precisam ser reabilitados estética e funcionalmente para que possam ser reintegrados às funções sociais. A prótese maxilofacial é um artefato de baixo custo, que pode resolver essa necessidade. Relato de caso: Esse artigo relata o caso de uma paciente de 19 anos submetida à exenteração de órbita para tratamento de Tumor Fibroso Solitário Retrorbitário que, após a cirurgia e radioterapia adjuvante, foi reabilitada por meio de prótese óculopalpebral em silicone. Conclusão: O caso foi considerado um sucesso e ressalta a importância do cirurgião dentista na equipe oncológica e o positivo impacto psicológico e social da reabilitação(AU)
Introduction: Surgical resection of head and neck tumors is an effective treatment, but it implies significant facial disfigurement depending on the location of the lesion. Those patients considered cured need to be rehabilitated aesthetically and functionally so that they can be reintegrated into social functions. The maxillofacial prosthesis is an artifact of low cost, which can solve thisneed. Case Report: This article reports the case of a 19-year-old patient who underwent orbit exanteration for the treatment of Solitary Retrorbital Fibrous Tumor, which, after surgery and adjuvant radiotherapy, was rehabilitated using an oculopebral prosthesis made of silicone. Conclusion: The case was considered a success and highlights the importance of the dental surgeon in the oncology team and the positive psychological and social impact of rehabilitation(AU)

OBJECTIVE: To assess the effectiveness of physical activity interventions in improving objective and patient-reported outcomes in HNC survivors. INTRODUCTION: Multiple guidelines recommend that head and neck cancer (HNC) survivors participate in regular physical activity. Physical activity is associated with improved outcomes and mortality in healthy individuals as well as in certain cancer populations. However, the effectiveness of physical activity interventions in HNC survivors is inadequately understood. METHODS AND RESULTS: Our literature search through December 2018 identified 2,392 articles. After de-duplication, title and abstract review, full-text review and bibliographic search, 20 studies met all inclusion criteria. Inclusion criteria included any full-body physical activity intervention in HNC survivors that did not target discrete organ sites or functions (e.g. swallowing). Study cohorts included 749 predominantly male participants with a mean age range of 48-63 years. At their conclusion, physical activity interventions were associated with at least one significant improvement in an objective or patient-reported outcome in 75% of studies. Aerobic capacity and fatigue were the most commonly improved outcomes. None of the included studies evaluated associations with survival or recurrence. Although traditional aerobic and resistance interventions were more common, a greater proportion of alternative physical activity (yoga and Tai Chi) interventions demonstrated improved objective and patient-reported outcomes. CONCLUSION: Physical activity interventions in HNC survivors often conferred some improvement in objective and patient-reported outcomes. Additional highly-powered, randomized controlled studies are needed to establish the optimal type, intensity, and timing of physical activity interventions as well as their impact on oncologic outcomes.

Introduction: Head and neck cancer patients often suffer from physical and cognitive impairments after cancer treatment. During rehabilitation, exercise therapy can improve physical function and quality of life (QoL). Surveys demonstrated patients' preference for home training with low- to moderate-intensity. This study was conducted in order to develope a suitable home-based training program. Therefore, the feasibility and effects of a low- to moderate-intensity exercise intervention on physical functions and QoL were evaluated. Methods: Training was conducted as supervised group training and consisted of mobilization, coordination, resistance, stretching, and relaxation exercises. The intervention lasted 12 weeks with 2 training sessions per week. Feasibility, attendance rate, physical function (eg, range of motion, 6-minute walk test [6MWT]), and QoL (eg, EORTC QLQ-30) were analyzed. Results: Ten out of 12 participants completed the intervention (83%) with an average attendance rate of 83%. Participants showed significant improvements in selected physical functions. For example, head rotation increased by 11.2° (P = .042), walking distance in the 6MWT increased by an average of 43.3 m (P = .010), and the global QoL scale improved by 8.2 points (P = .059). Additionally, there were positive changes in the physical function scale (P = .008), cognitive function scale (P = .015), and social function scale (P = .031) of the EORTC QLQ-30. Conclusion: Data indicate that the exercise program was feasible and had positive effects on physical function and QoL. Future research will analyze the effects of a home-based exercise program on physical function and QoL in a large-scale study.

Cancer affects millions of individuals, and approximately half will develop functional impairments. Cancers that commonly, either from direct effects or from its treatments, result in functional impairments include breast, head and neck, brain, and spinal cord tumors. There is a plethora of potential impairments including pain, spasticity, dystonia, weakness, and neurogenic bowel or bladder. This article reviews the functional impairments frequently encountered in breast, head and neck, brain, and spinal cord tumors. The authors also discuss management and treatment options incorporated in comprehensive cancer rehabilitation to address these impairments to maximize and maintain function and quality of life.

Objective: This study aims to investigate the responsiveness of the Danish treatment pathway for head-and-neck-cancer (HNC) patients receiving oral rehabilitation.Material and Methods: Eighteen HNC-patients who had received oral rehabilitation as well as five medical and four oral health care professionals involved in the treatment of HNC-patients filled in a questionnaire on responsiveness. The responsiveness was further described in individual interviews in the HNC-patients and focus group interviews in the health care professionals. All interviews were semi-structured and analysed using the grounded theory.Results: Patients and health care professionals overall reported good responsiveness of the pathway. Prompt attention was in both groups considered the most important aspect, although the patients found it difficult to cope mentally with the fast-track and the health care professionals reported insufficiencies giving prompt attention. The patients in general described a good relationship with their health care professionals, but along with the health care professionals also reported some problems regarding communication. Further, the health care professionals reported a gap between medical treatment and oral rehabilitation.Conclusions: The Danish treatment pathway for HNC-patients was, in general, evaluated positively. Communication and relationship between patient and health care professional can affect the responsiveness of the pathway.

BACKGROUND: Swallowing dysfunction after radiotherapy (RT) for head and neck cancer can be devastating. A randomized control trial compared swallow exercises versus exercise plus neuromuscular electrical stimulation therapy and found no overall difference in outcomes. METHODS: Quality of life (QOL), diet, and swallowing variables collected at discrete intervals on 117 patients were reanalyzed to test the hypothesis that shorter time between the completion of radiotherapy and beginning of the swallowing therapy program yielded improved outcomes. RESULTS: At baseline, subjects < 1 year post radiation had significantly better function than subjects >2 years post RT in several measures. Over the therapy program, the early group showed significant improvement in diet and QOL. Swallowing physiologic variables showed no difference between groups. CONCLUSION: Beginning a swallowing therapy program within 1 year of completion of radiotherapy demonstrates more consistent improvement in QOL and diet performance compared to later periods.

Purpose: The objectives of this scoping review were to summarize, understand, and disseminate findings from a broad body of literature on rehabilitation interventions used with survivors of head and neck cancer. Method: Searches were conducted in six databases. Inclusion criteria were studies of adult head and neck cancer survivors with a predefined primary rehabilitation outcome as a result of an intervention. Excluded were studies not written in English, opinion papers, or studies where the intervention was not carried out by a rehabilitation healthcare service. A second level, full-text review of the studies was conducted. A thematic analysis was used to examine and combine study findings. Results: A total of 3804 results were retrieved from all sources resulting in 39 papers that were analyzed. The thematic analysis of the included papers represented interventions focusing on swallowing and nutrition, speech, physical therapy, assistive devices, complementary and alternative modalities, comprehensive interdisciplinary programs, and preventive rehabilitation programs. Conclusion: This review has provided an overview of the scope of rehabilitation interventions available for survivors of head and neck cancer and preliminary information about their efficacy. This is foundational information for the development and refinement of rehabilitation interventions and programs for head and neck cancer survivors. Implications for Rehabilitation The existing evidence suggests that survivors of head and neck cancer can benefit from early screening of potential rehabilitation needs and being involved in preventive rehabilitation programs pre-surgery when possible. Rehabilitation programs should consider swallowing interventions for patients as evidence reports improved swallowing function, decreased pain and discomfort, and reduced duration of feeding tube use. Rehabilitation programs should consider nutritional interventions after radiotherapy: Patients benefited from stabilized weights, improved nutritional status, and an improved quality of life. Physical exercise interventions demonstrated improvements in physical function, muscular endurance, range of motion, overall quality of life, and showed reductions in pain, and fatigue.

Introduction Following (chemo)radiotherapy (C/RT) for head and neck cancer (HNC), patients return to hospital for regular outpatient reviews with speech pathology (SP) and nutrition and dietetics (ND) for acute symptom monitoring, nutritional management, and swallowing and communication rehabilitation. The aim of the current study was to determine the feasibility of a home-based telehealth model for delivering SP and ND reviews, to provide patients with more convenient access to these appointments. Methods Service outcomes, costs, and consumer satisfaction were examined across 30 matched participants: 15 supported via the standard model of care (SMOC), and 15 via the home-based telehealth model of care (TMOC). Results All patients were successfully managed via telehealth. The TMOC was more efficient, with a reduced number ( p < 0.003) and duration ( p < 0.01) of appointments required until discharge. Significant patient cost savings ( p = 0.002) were reported for the TMOC due to decreased travel requirements. While staff costs were reduced, additional telehealth equipment levies resulted in a lower but non-significant overall cost difference to the health service when using the TMOC. High satisfaction was reported by all participants attending the TMOC. Discussion The findings support the feasibility of a home-based telehealth model for conducting SP and ND reviews post C/RT for HNC.

INTRODUCTION: The incidence of head and neck cancer (HNC) in the UK is rising, with an average of 31 people diagnosed daily. Patients affected by HNC suffer significant short-term and long-term post-treatment morbidity as a result of dysphagia, which affects daily functioning and quality of life (QOL). Pretreatment swallowing exercises may provide additional benefit over standard rehabilitation in managing dysphagia after primary HNC treatments, but uncertainty about their effectiveness persists. This study was preceded by an intervention development phase to produce an optimised swallowing intervention package (SIP). The aim of the current study is to assess the feasibility of this new intervention and research processes within a National Health Service (NHS) setting. METHOD AND ANALYSIS: A two-arm non-blinded randomised controlled feasibility study will be carried out at one tertiary referral NHS centre providing specialist services in HNC. Patients newly diagnosed with stage III and IV disease undergoing planned surgery and/or chemoradiation treatments will be eligible. The SIP will be delivered pre treatment, and a range of swallowing-related and QOL measures will be collected at baseline, 1, 3 and 6â months post-treatment. Outcomes will test the feasibility of a future randomised controlled trial (RCT), detailing rate of recruitment and patient acceptance to participation and randomisation. Salient information relating to protocol implementation will be collated and study material such as the case report form will be tested. A range of candidate outcome measures will be examined for suitability in a larger RCT. ETHICS AND DISSEMINATION: Ethical approval was obtained from an NHS Research Ethics Committee. Findings will be published open access in a peer-reviewed journal, and presented at relevant conferences and research meetings. TRIAL REGISTRATION NUMBER: ISRCTN40215425; Pre-results.

Patterns of follow-up and survivorship care are changing in response to growing numbers of cancer survivors and an increasing recognition that traditional models are unsustainable and result in unmet needs. Clinicians have shown reluctance in changing conventional follow-up practices for patients with head and neck cancer. This study aimed to explore nurses' and allied health professionals' views and practices in relation to follow-up, holistic needs assessment and survivorship care in this patient group. An online survey of members of the British Association of Head and Neck Oncology Nurses was undertaken. The response rate was 43% (74 of 174). Findings revealed a range of existing models of follow-up, rehabilitation and support for people with head and neck cancer across the UK. Specialist staff were open to new models of care and to more responsibility, with adequate training and supervision. There were some gaps in the provision of comprehensive survivorship care and some specific areas of practice in which nurses lacked confidence, knowledge and skills, such as managing medications and complex symptoms. Further research is needed to develop and evaluate effective models of follow-up and support for a growing population of head and neck cancer survivors who have diverse and complex needs.

The aim of this study was to analyze retrospectively effects of exercise therapy on trismus related to head and neck cancer or as a consequence of its treatment, and to compare these effects with trismus not related to head and neck cancer. Medical records of patients referred to the department of physical therapy with the diagnosis trismus were retrieved and analyzed. Data of 27 patients with trismus related to head and neck cancer and data of eight patients with trismus not related to cancer were found. The number and type of exercises were registered from the records, as was the extent of mouth opening before and after exercise therapy. The median (IQR) number of exercise treatments was 4 (3-9.3). Exercises included active range of motion exercises, hold relax techniques, manual stretching and joint distraction. The increase in mouth opening was significantly (pAsunto(s)

RESUMEN
Surgical treatment of malignancies in the oral cavity and subsequent radiotherapy often result in an anatomic and physiological oral condition unfavorable for prosthodontic rehabilitation. The objective of this prospective study was to assess the effect of hyperbaric oxygen therapy on treatment outcome (condition of peri-implant tissues, implant survival, oral functioning and quality of life) of prosthodontic rehabilitation with implant-retained lower dentures in radiated head and neck cancer patients 6 weeks and 1 year after placing the new dentures. The treatment outcome was assessed in a group of 26 head neck cancer patients who were subjected to radiotherapy after tumour surgery. Standardized questionnaires were completed and clinical and radiographic assessments were performed. After randomization, endosseous Brånemark implants were placed in the anterior part of the mandible either under antibiotic prophylaxis (13 patients) or under antibiotic prophylaxis combined with pre and postsurgery hyperbaric oxygen (HBO) treatment (13 patients). In the HBO and non-HBO group eight implants (implant survival 85.2%) and three implants (implant survival 93.9%) were lost, respectively. Peri-implant tissues had a healthy appearance in both groups. Osteoradionecrosis developed in one patient in the HBO group. All patients functioned well with their implant-retained lower denture. The quality of life related to oral functioning and denture satisfaction were improved to a comparable extent in the HBO and non-HBO group. Implant-retained lower dentures can improve the quality of life related to oral functioning and denture satisfaction in head and neck cancer patients. Adjuvant hyperbaric oxygen therapy could not be shown to enhance implant survival in radiated mandibular jaw bone.

BACKGROUND: Advances in the management of oral malignancy have resulted in significant improvements in survival and functional outcome. Ablation of oral tissues and radiotherapy render many patients unable to wear conventional prostheses, and these patients are, thus, candidates for oral rehabilitation with osseointegrated implants. We aim to present outcomes and complications of such treatment over a 14-year period in a single unit. METHODS: Data were collected for 81 consecutive patients, most of whom had received microvascular free flap reconstruction after surgical ablation of oral squamous cell carcinoma. Three hundred eighty-six implants were placed after a delay of 12 months after surgery. Sixty-five percent of implants were placed in the anterior mandible. Radiotherapy was used in 47% of the patients, and hyperbaric oxygen treatment was routinely used in irradiated subjects during the latter half of the series. Retrospective analysis of implants and prostheses was made by use of case notes, radiographs, and a computerized database. RESULTS: Data are presented for 364 of the 386 implants in 77 of the 81 patients after a median follow-up of 4 years. Two hundred sixty-five (73%) of the implants were in function supporting prostheses, 56 (15%) had been lost, and 43 (12%) were present but not loaded (ie, "sleepers"). Implant loss seemed patient specific and was also correlated with host bone type. Thirteen percent of patients in whom implants were placed in the mandible lost at least one implant, and the equivalent values for the maxilla was 40%. Thirty-six percent of patients in whom implants were placed in bone graft or flap lost at least one implant. The effects of implant manufacture, dimensions, radiotherapy, and hyperbaric oxygen did not reach statistical significance in this series. Cases of a second primary malignancy were noteworthy; however, the impact of recurrence was minimized by the delay between resection and rehabilitation. Of the 42 fixed and 29 removable prostheses fitted, 12 (17%) failed. CONCLUSIONS: Implants placed in mandible were reliable, but failure rates in vascularized bone graft and maxilla were higher. Radiotherapy did not seem to prejudice implant survival, and hyperbaric oxygen had no demonstrable benefit in this series. Despite some persistent soft tissue problems and implant loss, most patients reached a successful prosthetic and functional outcome.

This paper discusses the use of extra-oral endosseous craniofacial implant (EOECI) therapy in irradiated bone. The survival rate of EOECIs in irradiated bone is reviewed and the controversy over the optimal time prior to place implants is described. The advantages and disadvantages of pre- and post-implant radiotherapy are addressed. The EOECI rehabilitation and osteoradionecrosis and the evidence of the potential role of hyperbaric oxygen are reviewed. Strategies for improving the clinical outcome of EOECIs are suggested.

Implant therapy is no longer considered impossible for patients who have received radiation treatment. However, the risk of osteoradionecrosis and failed osseointegration are barriers to implant therapy for this population. This paper reviews the published literature on the effects of radiation on tissue, such as osteoradionecrosis, hyperbaric oxygen therapy, and evaluates implant therapy in patients who have received radiation treatment, focusing on treatment of the mandible. Recommendations for dentists planning implant therapy for patients who have had radiation treatments are presented.

Plastic surgery represents a small but critical component of the comprehensive care of cancer patients. Its primary role in the treatment of cancer patients is to extend the ability of other surgeons and specialists to more radically treat cancer, offering patients the best opportunity for cure. Although the most convincing data for improved psychosocial well-being through plastic surgery is in the setting of breast cancer reconstruction after mastectomy, it is reasonable to assume that all patients who undergo major reconstruction to minimize deformity due to cancer therapy feel some improvement in quality of life. This article will provide an overview of the role of plastic surgery in cancer treatment.

PURPOSE: The current investigation was undertaken to study whether osseointegration of implants in irradiated tissues is subject to a higher failure rate than in nonirradiated tissues. It further aimed to study whether hyperbaric oxygen treatment (HBO) can be used to reduce implant failure. PATIENTS AND METHODS: Seventy-eight cancer patients who were rehabilitated using osseointegrated implants between 1981 and 1997 were investigated. Three groups of patients were compared: irradiated (A), nonirradiated (B), and irradiated and HBO-treated (C). In addition, 10 irradiated patients who had lost most of their implants received new ones after HBO treatment. These were compared as a case-control group. RESULTS: Implant failures were highest in group A (53.7%). Implant failure was 13.5% in group B and 8.1% in group C. The difference between group A and the other two groups was statistically significant (P = .001 to .0023, Mantell's test). HBO significantly improved implant survival in the case-control group from 34 of 43 implants lost to 5 of 42 lost (P = .0078). CONCLUSIONS: Implant insertion in irradiated bone is associated with a higher failure rate. Adjuvant HBO treatment can reduce the failures.
