Background : Noma can be a lethal disease and causes disfigurement in young children in low-resource countries, particularly in Africa. In these settings, 80% of the population mainly consult traditional healers for healthcare problems. Our study aimed to describe the sociodemographic characteristics of traditional healers and to assess their knowledge of noma. Methods : We conducted a survey among traditional healers in three Malian regions from May 2015 to January 2016 and collected data on sociodemographic characteristics, professional activity, knowledge, and experience of noma and collaboration with modern medicine. Results : Among 770 traditional healers invited to participate, 732 responded (95%) (mean age, 54.5 years). Most were illiterate (66.3%), which was associated with older age ( p < 0.001). Although they treated all types of disease, only 10.5% had some knowledge of noma, with regional differences ( p < 0.001). Conclusion : Noma is poorly known among traditional healers, especially in remote areas. Our findings suggest a lack of interest among young people for traditional medicine, implying an imminent decrease of healers, and thus the need for national health systems to strengthen and promote access to modern health care. Training programmes to improve the early diagnosis referral of noma patients should include all types of primary health workers.

Extraarticular ankylosis occurs frequently in children suffering from noma sequelae. Over 20years of operating on these patients, we observed high recurrence of mouth opening limitation. We therefore progressively changed our surgical strategy. This retrospective study compares the impact of different parameters (types of surgery, noma type, physiotherapy compliance, age and sex) on immediate and long-term mouth opening. It includes a series of 121 patients with extraarticular ankylosis operated on between 1990 and 2015. Soft tissue reconstruction evolved from local and pedicled flaps to large free flaps. Mouth opening was performed by bone-bridge excision, sometimes associated to contralateral coronoidectomy. Mouth opening technique including bilateral coronoidectomy with free flap reconstruction was the only independent factor for significantly better immediate mouth opening with a mean increase of 8.7mm [95% confidence interval (CI) 4.3-13.1, P<0.001) and this effect was maintained in the 3years of follow-up. Another positive factor related to long-term results was excellent physiotherapy, while noma type 4 was a negative factor. Recurrence remains problematic in the management of noma sequelae. If physiotherapy and long-term follow-up cannot be offered, patients should not be operated on, because if limitation of mouth opening recurs, oral feeding may become impossible when a facial defect has been reconstructed., (Copyright © 2018 International Association of Oral and Maxillofacial Surgeons.
