Acellular Dermal Matrix, Osseoplastic Flap, and Transnasal Endoscopic Approach for Frontal Mucocele.

Abstract

The primary objective of this study is to suggest the use of acellular dermal matrix through an osteoplastic flap and transnasal endoscopic treatment for the management of frontal mucoceles. The secondary objective is to propose the characteristics to choose this approach. A retrospective cohort study was carried out on patients with frontal mucoceles of different etiologies where an osteoplastic flap was made to address the sinus and subsequently obliterated with acellular dermal matrix. A cohort of 11 patients were included in the study, 6 (67%) were female and 5 (56%) were male, with a mean age of 56 years (range 35-71). The majority of patients (73%) with a history of trauma and all the patients were treated with frontal osteoplastic flap and obliteration with acellular dermal matrix. No evidence of recurrence in a follow-up period with a mean of 18 months and a low rate of complications. The frontal osteoplastic flap and obliteration with acellular dermal matrix is a simple and safe technique to perform with low morbidity. Also, an orbital reconstruction can be performed simultaneously.
