Objectives: Frontal sinus pneumocele is a rare condition characterized by abnormal expansion of the air-containing sinus beyond the normal margins of the frontal bone. The etiology remains unclear but has been associated with developmental, neoplastic, inflammatory, and post-traumatic causes. Few reports in the literature describe the surgical management of frontal sinus pneumocele. We focus on describing the evaluation, work-up and surgical treatment of this condition. Study Design: A comprehensive review of the literature and retrospective case series of 3 patients with frontal sinus pneumocele. Methods: A case series and literature review on the surgical management of frontal sinus pneumocele. Results: We present a case series of patients who presented with frontal sinus pneumocele in which there was thinning of the overlying anterior table of the frontal bone. Conventional methods that aim to contour the external surface of the frontal bone cannot be applied in this clinical situation. We describe a surgical method in which correction of frontal bossing was performed by the creation of an osteoplastic flap with recession of the anterior table into the sinus and fat obliteration of the remaining cavity. Conclusions: Frontal sinus pneumocele is a rare condition that presents a diagnostic and surgical challenge. Few reports in the literature describe the surgical management of the cosmetic deformity. We describe a novel technique of surgical correction utilizing the osteoplastic flap and recession of the anterior table of the frontal sinus.
