Introduction. In Cameroon, little scientific work has been devoted to maxillofacial substance loss (MSL) and maxillofacial prosthetic needs. The aim of our study was to evaluate the need for maxillofacial prosthetic rehabilitation in patients with acquired maxillofacial SDB in the city of Yaoundé. Methodology. We carried out a descriptive cross-sectional study over a period of eight months, from November 2023 to June 2024 in 2 hospitals, namely: Yaoundé University Hospital (CHUY) and Yaoundé Central Hospital (HCY). The patients included were those who had suffered maxillofacial trauma, benign or malignant tumour pathologies with sequelae of substance loss requiring maxillofacial rehabilitation or who had maxillofacial substance loss. Results. We registered 30 patients with a sex ratio of 1.72. The mean age was 34.17 years. The aetiology of maxillofacial PDS was consecutive to an interrupting excision or enucleation of the tumour in 95% of cases. Benign tumours were the most common (89.29%). Loss of substance was more common in the mandible (86.67%). Loss of substance in the mandible was classified by CARIOU as follows: non-interrupting loss of substance, type Aa (11.53%), type Ab (3.85%), type La (19.23%) and type Lb (19.23%). Aesthetic damage was the main reason for rehabilitation in 91.66% of cases. Loss of mandibular interrupting substance was reconstructed using titanium plates in 80% of cases. The need for exoprostheses was observed in 92.30% of cases, all represented by endo-oral prostheses. Conclusion. The need for prosthetic rehabilitation to alleviate maxillofacial SDB arises essentially from benign aetiologies and mainly concerns the mandible.
