[PMID: 39208868 DOI: 10.1016/j.joms.2024.08.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 07/26/2024] [Accepted: 08/05/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Osteoradionecrosis of the jaw (ORN) is a late complication of radiation therapy. Radiation-induced fibrosis is the most likely mechanism for developing ORN, and statins are effective against radiation-induced fibrosis. However, no reports have indicated the direct effectiveness of statins in treating ORN. PURPOSE This study aimed to measure the association between statin exposure and ORN disease resolution. STUDY DESIGN, SETTING, SAMPLE This retrospective cohort study included patients with ORN diagnosed between January 2008 and December 2020 at the Hospital's Department of Oral and Maxillofacial Surgery. Patients who were immunocompromised or followed up for < 6 months were excluded. PREDICTOR VARIABLE The predictor variable was statin exposure, which was defined as the use of statins for dyslipidemia. MAIN OUTCOME VARIABLE The main outcome variable was ORN disease progression status (good prognosis). Patients who showed full recovery and improvement were included in the good prognosis group, and those who showed invariance and deterioration were included in the poor prognosis group. COVARIATES We analyzed the clinicodemographic including the age of onset, sex, history of smoking, alcohol consumption, history of chemotherapy, tumor site, association with dental treatment, location (maxilla or mandible), the time to ORN onset from radiation therapy, and stage of ORN, and treatment characteristics including hyperbaric oxygen therapy, long-term macrolide administration, and sequestrectomy. ANALYSES We analyzed the association between statin exposure or covariates and time to ORN improvement using bivariate and multivariate Cox regression. The significance level was set at P = .05. RESULTS We analyzed 102 patients, and the improvement rate was 32.4%. The favorable prognostic factors were statin exposure (adjusted hazard ratio [HR], 3.71; 95% confidence interval [CI], 1.62 to 8.50; P = .002), onset in the maxilla (HR, 2.15; 95% CI, 1.02 to 4.55; P = .045), and stage 1 of ORN (HR, 2.65; 95% CI, 1.20 to 5.83; P = .016). CONCLUSION AND RELEVANCE In this study, statin exposure, onset in the maxilla, and stage 1 of Lyons's classification were favorable prognostic factors for ORN. Although this study's findings were insufficient to recommend statin use for ORN, statins may be a novel and effective treatment for ORN.

Abstract
PURPOSE Osteoradionecrosis (ORN) is a severe late complication of head and neck radiation therapy shown to have profound negative effect on the quality of life of cancer survivors. Over the past few decades, improvements in radiation delivery techniques have resulted in a decrease in the incidence of ORN. However, even with modern radiation therapy techniques, ORN remains an important clinical concern. In recent literature, there is a wide range of reported ORN rates from 0% to as high as 20%. With such a high level of variability in the reported incidence of ORN, oncologists often encounter difficulties estimating the risk of this serious radiation therapy toxicity. METHODS AND MATERIALS In this review, the authors present a summary of the factors that contribute to the high level of variability in the reported incidence of ORN. RESULTS Variable definition, variable grading, and heterogeneity of both study inclusion criteria and treatment parameters can each significantly influence the reporting of ORN rates. CONCLUSIONS Given numerous factors can affect the reported incidence of ORN, a thorough understanding of the clinical context behind the reported ORN rates is needed to comprehend the true risk of this important radiation therapy toxicity.

Abstract
AIMS Osteoradionecrosis (ORN) is a serious toxicity of head and neck radiotherapy. It predominantly affects the mandible. Extra-mandibular ORN is rare. The aim of this study was to report the incidence and outcomes of extra-mandibular ORNs from a large institutional database. MATERIALS AND METHODS In total, 2303 head and neck cancer patients were treated with radical or adjuvant radiotherapy. Of these, extra-mandibular ORN developed in 13 patients (0.5%). RESULTS Maxillary ORNs (n = 8) were a consequence of the treatment of various primaries (oropharynx = 3, sinonasal = 2, maxilla = 2, parotid = 1). The median interval from the end of radiotherapy to the development of ORN was 7.5 months (range 3-42 months). The median radiotherapy dose in the centre of the ORN was 48.5 Gy (range 22-66.5 Gy). Four patients (50%) healed in 7, 14, 20 and 41 months. All temporal bone ORNs (n = 5) developed after treatment to the parotid gland (of a total of 115 patients who received radiotherapy for parotid gland malignancy). The median interval from the end of radiotherapy to the development of ORN was 41 months (range 20-68 months). The median total dose in the centre of the ORN was 63.5 Gy (range 60.2-65.3 Gy). ORN healed in only one patient after 32 months of treatment with repeated debridement and topical betamethasone cream. CONCLUSION Extra-mandibular ORN is a rare late toxicity and this current study provides useful information on its incidence and outcome. The risk of temporal bone ORN should be considered in the treatment of parotid malignancies and patients should be counselled. More research is required to determine the optimal management of extra-mandibular ORN, particularly on the role of the PENTOCLO regimen.

Abstract
BACKGROUND Osteoradionecrosis (ORN) of the maxilla is a rare disease. In contrast with a mandibular predominance, maxillary ORN has not been widely reported. OBJECTIVE To review clinical features, surgical treatments, and results of maxillary ORN and offer recommendations for surgical decision-making. MATERIAL AND METHODS We retrospectively reviewed medical records of maxillary ORN at our hospital between 2002 and 2017. Clinical data were collected, including age, sex, primary tumor characteristics, radiotherapy dose, clinical findings of maxillary ORN, and treatment outcomes. Descriptive statistics and multiple factors were analyzed. RESULTS Twenty-four patients were included for analysis. The primary symptoms of maxillary ORN were pain, trismus, pus, bone exposure, and skin fistula. Twenty (83.3%) patients were completely cured after single-operation. Thirteen patients underwent sequestrectomy, and the cure rate was 76.9% (10/13). Eleven patients received segmental osteotomy and flap reconstruction, with the cure rate of 90.9% (10/11). There was no significant statistical difference in the cure rate between these two groups (p = .596). CONCLUSIONS AND SIGNIFICANCE Compared with mandibular ORN, the surgical effect of maxillary lesions is better and the choice of operation methods can be relatively conservative. Both sequestrectomy and segmental osteotomy with flap reconstruction can achieve good results in appropriate conditions.

Abstract
The implementation of radiotherapy in the multimodal treatment of advanced head and neck cancer has greatly improved survival rates. In some patients, however, this benefit comes at the potential expense of the tissue surrounding the primary site of malignancy. Osteoradionecrosis (ORN) of the facial bones, in particular the maxilla, is a debilitating complication of radiation therapy. Exposure to ionizing radiation results in devitalization of underlying bone with necrosis of adjacent soft tissue. Controversy surrounding appropriate early intervention in ORN persists and no consensus for clinical treatment has been established. In the present article, we review the pathophysiology of maxillary ORN and discuss the role of both conservative medical therapy and reconstruction.

Abstract
The authors reported a case of extensive maxillary osteoradionecrosis. The maxilla was resected and reconstructed with fibula musculocutaneous flap. It was the first reported that the osteoradionecrotic maxilla was reconstructed with free vascularized bone. The musculocutaneous flap might be a better choice of maxillary osteoradionecrosis reconstruction instead of the simple soft-tissue flap.

Abstract
Osteoradionecrosis occurs in 4.74% to 37.5% of patients following radiation therapy for head and neck cancer. Osteoradionecrosis mostly happens in the mandible but seldom occurs in other maxillofacial bones. Here, the authors reported a rare case of zygomatic osteoradionecrosis which occurred after maxillectomy and then radiotherapy because of maxillary myoepithelial carcinoma. After resection of zygoma sequestrum, the defect was repaired with forehead flap and healed uneventfully.

Abstract
BACKGROUND Osteoradionecrosis of the jaw (ORNJ) is a well-recognized complication of radiotherapy. The purpose of this study was to assess predictive factors for the development of ORNJ. METHODS A retrospective study of 325 patients with head and neck squamous cell carcinoma (HNSCC) treated at one institution between January 1, 1999, and December 31, 2008, was conducted. Outcome measure was the presence/absence of ORNJ. Time to event was recorded and Cox proportional hazard regression analysis was used to determine statistically significant predictive factors. RESULTS Fifty-nine patients had ORNJ. Statistical analysis using Cox regression analysis identified several statistically significant variables: dentoalveolar surgery; peri-resective surgery of the jaw; continued tobacco usage after radiotherapy, diabetes mellitus type 2 (DM2); and total radiation dose. CONCLUSION Patients at greater risk of developing ORNJ can be identified and measures can be instituted to reduce its incidence and expedite management when it does occur.

Abstract
BACKGROUND Although hyperbaric oxygen therapy (HBOT) is used to treat chronic radiation tissue injury, clinical evidence supporting its use in maxillary bone osteoradionecrosis (ORN) is lacking. Therefore, the purpose of this study was to report our results of collected patient outcomes from a single center's large experience using HBOT to treat maxillary bone ORN. METHODS From 1999 to 2015, 21 patients received treatment for maxillary bone ORN at our center. The medical records were retrospectively reviewed for the following variables: age, sex, comorbidities, tumor stage and site, previous surgery, previous radiotherapy or chemoradiation therapy, HBOT data, response to treatment and further management. RESULTS A positive clinical outcome from HBOT occurred in 85.7% of patients with ORN and was proven radiologically in 14 of 15 patients (93.3%). In 5 patients, reconstructive surgery was required thereafter. CONCLUSION Controversy exists regarding the management of ORN of the maxillofacial skeleton. Our large, single-center experience probably supports the efficacy of HBOT for maxillary bone ORN. © 2016 Wiley Periodicals, Inc. Head Neck 39: 275-278, 2017.

Abstract
PURPOSE Osteoradionecrosis is a complication of head and neck radiotherapy, with a difficult resolution and no well-established treatment. The disease progression can cause important loss on patient's quality of life after cancer treatment. The options for treatment are limited and include clinical monitoring, prescription, or surgical procedures. As an alternative for bone necrosis treatment, a combination of drugs, pentoxifylline and tocopherol, can be used. Studies have shown that this combination significantly reduces chronic radiotherapy damage. The article reports successful treatment with this prescription protocol. METHODS We report three cases of patients referred to the Service of Oral and Maxillofacial Surgery at Erasto Gaertner Hospital, in Curitiba, Brazil. They were submitted to radiotherapy for the treatment of malignant head and neck tumors and later developed osteoradionecrosis. They were treated with the combination pentoxifylline and tocopherol. RESULTS All patients achieved complete remission in less than 1 year, with complete healing of bone exposure and without clinical symptoms. CONCLUSIONS This results show that this combination of drugs is beneficial in cases of bone necrosis induced by radiation, avoiding more aggressive treatments and reducing morbidity.

Abstract
BACKGROUND Mandibular osteoradionecrosis (ORN) is a well-known complication of head and neck radiotherapy; however, ORN of the cervical spine is rarely reported. METHODS Herein, we present a patient with a history of tonsillar carcinoma treated with chemoradiation who developed acute, severe progressive neck pain due to cervical spine collapse as a result of ORN. We also discuss diagnosis and treatment of cervical ORN based on a review of the literature. RESULTS The patient was successfully treated with antibiotics and surgical debridement and fixation. CONCLUSION Delayed diagnosis of cervical ORN can result in marked disability and pain due to spinal cord compression, as well as serious deformity and instability requiring surgical intervention, and even death. It is important for otolaryngologists who treat head and neck malignancies to be aware of this potential complication so that patients may be diagnosed as early as possible and treated with conservative measures.

Abstract
Describing dose constraints for organs at risk in external beam radiotherapy is a key-point in order to maximise the therapeutic ratio. In head and neck irradiation, mandible is frequently exposed to ionising radiation-related complications. Those complications will be exposed after a short description of anatomical and physiopathological aspects. A literature search was performed using the Pubmed-Medline database, with following keywords "Osteoradionecrosis, Radiotherapy, Mandible, Toxicity, Organ at risk, Trismus". Incidence and dose constraints will be reported. The incidence of osteoradionecrosis decreased since the 1990s, but it remains a dreaded late complication of head and neck cancer radiotherapy. It essentially occurs with cumulative doses of 66 Gy on the mandible (standard fractionation) applied to a significant volume. Respecting oral care is crucial to avoid this kind of complication. The respect of the dose-constraint described should not lead to undertreat tumor bed in a curative intent. Trismus related to ionising radiation is poorly described. Literature data cannot lead to describe precise dose constraints.

Abstract
PURPOSE To critically analyze controversial osteoradionecrosis (ORN) prevention techniques, including preradiation extractions of healthy or restorable teeth and the use of prophylactic antibiotics or hyperbaric oxygen (HBO) treatments for preradiation and postradiation extractions. METHODS The author reviewed ORN studies found on PubMed and in other article references, including studies on overall ORN incidence and pre- and postradiation incidence, with and without prophylactic HBO or antibiotics. RESULTS Owing in part to more efficient radiation techniques, the incidence of ORN has been declining in radiation patients over the last 2 decades, but the prevention of ORN remains controversial. A review of the available literature does not support the preradiation extraction of restorable or healthy teeth. There is also insufficient evidence to support the use of prophylactic HBO treatments or prophylactic antibiotics before extractions or other oral surgical procedures in radiation patients. CONCLUSIONS To prevent ORN, irradiated dental patients should maintain a high level of oral health. A preradiation referral for a dental evaluation and close collaboration by a multidisciplinary team can be invaluable for radiation patients. As with most other dental patients, restorable and healthy teeth should be retained in irradiated patients. The use of prophylactic HBO or antibiotics should be reconsidered for preradiation and postradiation extractions.
