Conocemos poco sobre el Noma o Enfermedad Cancrum Oris. Esta entidad afecta a niños con malnutrición crónica, poca higiene oral, poco desarrollo sanitario y enfermedades concurrentes debilitantes. Existe un consenso general sobre que el Noma empieza como una gingivitis; en su fase aguda, puede haber respuesta al tratamiento antibiótico, no obstante, las secuelas tras su curación incluyen daños estéticos y funcionales variables, que pueden requerir cirugía reconstructiva. Presentamos 3 casos de anquilosis mandibular que en el examen preoperatorio presentaron dimorfismo mandibular, fusión de hueso maxilar y mandibular y anquilosis de la articulación témporomandibular. La ortopantografía y la Tomografía Axial Computerizada (TAC) fueron muy útiles en la planificación de la cirugía. El tratamiento quirúrgico consistió en todos los casos en la resección del hueso anquilótico y la reconstrucción con injerto condrocostal en uno de los casos. En el postoperatorio se siguió fisioterapia intensiva. Clínicamente todos los pacientes mostraron una gran mejoría en la masticación, la alimentación y el habla, obviamente debido a una buena oclusión. El problema más común fue la baja colaboración en la rehabilitación mandibular por parte de los pacientes.Little is known about Noma or Cancrum Oris Disease. This entity affects to children with chronic malnutrition, poor oral hygiene, poor environmental sanitation and debilitating concurrent illness. There is general consensus that noma starts as gingivitis. The acute stage responds readily to antibiotic treatment. The sequelae after healing include variable functional and aesthetic impairments, which require reconstructive surgery. We report 3 cases of mandibular ankylosis. Preoperative examination revealed mandibular dismorphism, fusion of maxilla and mandible and ankylosis of the temporomandibular joint. Orthopantography and Computed Thomography scan (TCS) were very useful in planning surgery. The surgical treatment performed consisted in ankylotic bone resection in all cases, accompanied with condrocostal graft reconstruction in one case. All patients continued postoperatively with an intensive physiotherapy. Clinically all patients showed an improvement in eating, chewing and speaking, obviously due to good occlusion. Low collaboration with the mandibular rehabilitation was the most common problem.

Investigation of cranial and spinal deformities in Atlantic salmon smolts from Chile immediately after sea transfer, over two successive crops, demonstrated ankylosis of the mandibular articulation, spinal foreshortening, fracture of vertebrae and rarefaction of osseous and cartilaginous tissues including the operculum. As a result the mouth was permanently agape and opercula could be folded back on themselves. All affected fish had been transferred to sea water at 20 °C plus and fed on particular commercial diets. Fish in cooler areas, or on diets high in vitamin C and phosphorus in the high temperature zone, were clinically normal. The condition has not recurred following dietary adjustment.
