Sinonasal mucous cyst : a rare complication of septorhinoplasty

الملخص EN

Introduction : Septorhinoplasty is a common performed surgery.

Late complications of septorhinoplasty are uncommon but may be serious and difficult to manage.

Nasal septal mucous cyst is a rare post-operative complication.

Objectives : We aim for discussing the etiological theories and suggesting strategies to prevent this complication.

Case report : We report a case of septal nasal cyst developed 15 years after a closed septorhinoplasty procedure.

It was a 68-year old man presenting with a chronic progressive headache with intermittent rhinorrhea.

Rhinologic examination revealed a prominent bulge in the posterosuperior wall of bilateral nasal fossa.

CT scan and MRI helped make the diagnosis of a sinonasal mucous cyst.

Complete removal of this formation was performed using an intranasal endoscopic surgery.

Conclusion : It seems that the proliferation of entrapped fragments of epithelial tissue is the cause of this phenomenon.

To avoid such a complication, procedures of septorhinoplasty should be performed appropriately and mucosal lining should be kept intact.
