          Abstract

          RESUMEN Introducción: Los bifosfonatos constituyen una familia de medicamentos cuya acción principal es la inhibición de la reabsorción ósea, uno de cuyos efectos secundarios es la osteonecrosis maxilar (OMAB). En 2010 comenzaron a publicarse casos de osteonecrosis asociados a un nuevo fármaco, el denosumab. En 2014 se recomendó cambiar el nombre de OMAB por osteonecrosis maxilar asociada a medicamentos (OMAM). El objetivo de este trabajo es revisar una serie de casos de OMAM tratados en nuestro servicio y reflejar la experiencia adquirida con las distintas opciones terapéuticas según la clasificación clínica definida por la American Association of Oral and Maxillofacial Surgeons (AAOMS). Materiales y métodos: Se recogió retrospectivamente un grupo de 19 pacientes con diagnóstico de OMAM, manejados desde 2005 hasta 2015. Su estadio fue determinado según la clasificación de la AAOMS y Ruggiero. Las lesiones fueron tratadas según sus características clínicas y radiológicas. Resultados: Su edad media fue de 75 años. La enfermedad de base era osteoporosis en 11 pacientes (58%), cáncer de próstata en 2 (11%), cáncer de mama en otrod 2 (11%) y mieloma múltiple en 4 pacientes (20%). En 9 pacientes el bifosfonato utilizado era intravenoso (47%); en los 4 restantes se usó la vía oral (alendronato e ibandronato, 21%) y el denosumab se administra por vía subcutánea. Los pacientes en estadio 3 fueron tratados en todos los casos con mandibulectomía segmentaria. Tres de ellos fueron reconstruidos con colgajo microquirúrgico de peroné y uno con barra mandibular más cierre directo. Fueron tratados mediante secuestrectomía 7 pacientes, de los cuales 5 tenían estadio 2 y 2 tenían estadio 1. Con desbridamiento local solo fue tratado un paciente, que presentaba estadio 1. El tratamiento conservador se aplicó al resto de los pacientes estadio 1 (4 pacientes) y a 3 pacientes del estadio 2. Conclusiones: El tratamiento de la OMAM depende del estadio de la enfermedad; la mandibulectomía es un tratamiento efectivo en el estadio 3 y la secuestrectomía en el estadio 2; el estadio 1 suele controlarse con tratamiento conservador.

          ABSTRACT Introduction: Bisphosphonates are a family of drugs used to inhibit bone resorption. One of their secondary effects is osteonecrosis of the jaws (ONJ). In 2010, scientists began to publish cases of osteonecrosis of the jaws associated with a new drug, denosumab. In 2014 it was recommended to change the name of ONJ to medication-related osteonecrosis of the jaws (MONJ). The aim of this article is to review a case series of MONJ treated in our Department, and present our experience in the different treatment options according to the clinical classification defined by the American Association of Oral Maxillofacial Surgeons (AAOMS). Materials and methods: A retrospective review was performed on 19 patients with MONJ, who were managed between 2005 and 2015. The clinical staging was according to the classification of the AAOMS and Ruggiero. The lesions were treated according to their clinical and radiological presentation. Results: The mean age was 75 years. The underlying disease was osteoporosis in 11 patients (58%), prostate cancer in 2 patients (11%), breast cancer in 2 patients (11%), and multiple myeloma in 4 patients (20%). Intravenous bisphosphonates were used in 9 (47%) patients, and oral in the remaining 4 (alendronate and ibandronate, 21%), with denosumab being administered subcutaneously. Stage 3 patients were treated in all cases with segmental mandibulectomy. Three of them were re-constructed with a microsurgical fibula flap, and onw with bar and direct closure. Sequestrectomy was used to treat 7 patients, of which 5 had stage 2, and 2 stage 1. One patient with stage 1 was treated with local debridement. Conservative treatment was applied to the rest (4) of the stage 1 patients, and 3 stage 2 patients. Discussion: Mandibulectomy is an effective treatment for stage 3, sequestrectomy for stage 2, and conservative measures for stage 1. This pathology is also associated with other drugs, such as denosumab, which is why the term had changed to medication-related osteonecrosis of the jaw. Conclusions: MONJ treatment depends on the stage of the disease, with mandibulectomy being an effective treatment in stage 3, sequestrectomy in stage 2 and stage 1 is usually controlled with conservative treatment.

              What is the role of hyperbaric oxygen in the management of bisphosphonate-related osteonecrosis of the jaw: a randomized controlled trial of hyperbaric oxygen as an adjunct to surgery and antibiotics.

              This study tested hyperbaric oxygen (HBO) as an adjunct to surgery and antibiotics in the treatment of bisphosphonate-related osteonecrosis of the jaw (ONJ) and evaluated its effects on gingival healing, pain, and quality of life. The investigators implemented a randomized controlled trial and enrolled a sample composed of patients with ONJ, where the predictor variable was HBO administered at 2 atm twice a day for 40 treatments as an adjunct to conventional therapy of surgery and antibiotics versus conventional therapy alone. Over the next 24 months, oral lesion size and number, pain, and quality of life were assessed. Forty-six patients (mean age, 66 yrs; 57% women) contributed data to the trial. There were no statistically significant differences in the distribution of variables used to assess randomization success between the HBO and standard treatment groups. Seventeen of 25 HBO-treated patients (68%) improved versus 8 of 21 controls (38.1%; P = .043, χ(2) test). Mean time to improvement was 39.7 weeks (95% confidence interval [CI], 22.4 to 57.0 weeks) for HBO-treated patients versus 67.9 weeks (95 CI, 48.4 to 87.5 weeks) for controls (P = .03, log-rank test). However, complete gingival healing occurred in only 14 of 25 HBO-treated patients (52%) versus 7 of 21 controls (33.3%; P = .203, χ(2) test), and time to healing was 59 weeks (95% CI, 42.8% to 75.8%) for HBO-treated patients versus 70 weeks (95 CI, 52.2% to 88.36%) for controls (P = .32, log-rank test). Pain decreased faster for HBO-treated subjects (P < .01, linear regression). Quality-of-life scores for physical health (P = .002) and perceived health (P = .043) decreased at 6 months for control group but for not the HBO group. ONJ is multifactorial and no single treatment modality is likely to reverse it; however, it is treatable and even advanced presentations can improve with intensive multimodal therapy. Clinically, HBO appears to be a useful adjunct to ONJ treatment, particularly for more severe cases, although this study was underpowered to fully support this claim.
