Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective is to evaluate the proportion of healing (defined as an area of bone exposure (ABE) < 5 mm) in patients receiving PENTO in osteochimionecrosis at 12 months;Secondary Objective: The secondary objectives are : - to describe the evolution of the modified SOMA score - to describe the nutritional parameters evolution, - to follow the EBA evolution, - to evaluate the treatment tolerance (description of adverse events) at 12 months. ;Primary end point(s): The primary endpoint is healing as defined by an exposure bone area (EBA) less than 5 mm at 12 months. It will be expressed as the percentage of patients who achieved healing (EBA < 5 mm) at 12 months;Timepoint(s) of evaluation of this end point: 12 months after treatment

Secondary

MeasureTime frame
Secondary end point(s): • The evolution of the modified SOMA score (qualitative and quantitative items) over 12 months: 0 -> 26 : Subjective: - Pain (occasional/minimal, intermittent/tolerate, persistent/intense, refractory) - Chewing (difficult with solids, with soft food, gastrostomy) Objective: - Bone exposure (minimal ulceration, 4 cm/fracture) - Trismus (minimal, 1-2 cm mouth opening, 0.5-1 cm, < 0.5cm) Management: - Pain (occasional, regular non-morphine treatment, regular morphine treatment, surgery) - Bone exposure (mouthwash, antibiotic therapy, debridement/HBO) Analytic: - Mandibular radiography (doubts, heterogeneous, sequestration, fracture) • Evolution of nutritional parameters over 12 months: - Patient's weight and BMI - Albuminemia in g/L (nomes 35-50 g/L) - Pre-albuminemia in mg/L (norms 250-350 mg/L) • Dimension and evolution of ABE (clinical) over 12 months: - Quantitative assessment: D dimension = major axis measurement of mucosal loss - Evolution: Relative regression D (= (D at x months - D at inclusion)/D at inclusion) • Collection of adverse events over 12 months, according to their nature, severity, severity (mild, moderate, severe) and causality;Timepoint(s) of evaluation of this end point: 12 months
