Abstract
Nasal dermoid sinus cyst (NDSC) is a rare congenital lesion, typically presenting at birth or in early infancy. Treatment of NDSC includes complete resection of the mass and the sinus tract, which may extend intracranially. Incomplete resection of the track is associated with high recurrence. We were looking for methods to delineate the NDSC track, without increasing the financial burden to the patient.
Highlights
Nasal dermoid sinus cysts (NDSC) are uncommon, occurring in 1 in 20000 to 40000 live births [1]
We advocate the use of methylene blue (MB) for precise and complete excision of NDSC
There was no evidence of bony erosion along anterior cranial fossa and crista galli appeared to be normal for the age (Figure 4)
Summary
Nasal dermoid sinus cysts (NDSC) are uncommon, occurring in 1 in 20000 to 40000 live births [1]. We demonstrate an effective surgical approach involving intraoperative visualization of the sinus track with methylene blue (MB) dye to facilitate complete resection and reduce the incidence of recurrence.
