Medical and surgical Material and method: Retrospective study of rhinoscleroma conducted in the ENT and head treatment and neck surgery departments in Côte d’Ivoire from January 1980 to December 2008 including the cases of confirmed rhinoscleroma and the treated cases. Results: Fourteen cases of rhinoscleroma were found in 28 years. The early manifestations were not specific enough so the patients were seen with clinical status with obvious disorders or physical discomfort. Treatment was medical and surgical. Medical therapy was based on streptomycin, thiopenicol or ciprofloxacin administration. Surgery consisted in removing the fibrous adhesions to correct the functional and aesthetic disorders. Conclusion: Rhinoscleroma has become a more and more rare disease because of the sen- sitivity to the new molecules. Diagnosis can be difficult and delayed because of its clinical polymorphism. © 2010 Elsevier Masson SAS. All rights reserved.

The study included nine male and five female patients aged from 16 to 81. Mean age was 33.4. The popula- tion included nine natives of Côte d’Ivoire and five foreigners among whom two natives of Burkina Faso, two Malians and one Guinean. Among the natives of Côte d’Ivoire, five were originally from the north of the country. Patients’ monthly income was below guaranteed minimum income (GMI). The delay in consultation varied between 1 month and 8 years with an average of 2 years. The patients consulted for nasal tumefaction (11 cases), permanent nasal obstruction (seven cases), endobuccal tumefaction (one case), dysphonia (three cases), mouth breathing (three cases). These signs were associated in some patients.
