Paranasal sinus mucoceles, therapeutic solution through external surgical approach

Mucoceles are benign, expansive, cystic tumors, affecting especially the adult, with development in the paranasal sinuses. Clinical symptoms are not specific. These are rare conditions that originate within the sinusal mucosa, favoured by the obstruction of the sinus ostium. Due to the inflammation and the expansive character of the tumor, with the erosion of the bony walls, combined forms can develop, with the involvement of two or more sinuses, most frequently with fronto-ethmoidal localization. The authors carry out a clinical retrospective study on 25 cases of mucoceles of the paranasal sinuses, diagnosed and treated in the ENT Clinic of the “Sfantul Spiridon” Emergency Clinical Hospital Iasi, during 2015-2019. The authors insist on aspects related to clinical and radiological diagnosis (CT scanner), as well as surgical treatment by external approach. The postoperative evolution is generally simple, with full recovery, without complications or recurrences. The diagnosis of the mucoceles of the paranasal sinuses consists in radiologic techniques by preoperative CT scan examination, intraoperative macroscopic aspect and histopathological result. Surgical approach with complete excision of the tumor and creating a new sinusal drainage path prevents the occurrence of recurrences.
