Abstract:
Lesions of the frontal sinus (FS) are always
a surgical challenge. Conventional endonasal endoscopic
techniques do not provide complete access inside the FS. This
is especially true with laterally placed lesions like mucocele or
post-traumatic cerebrospinal fluid (CSF) leak from FS. Standard
procedures like osteoplastic flap and endoscopic modified
Lothrop are not feasible for these smaller unilateral lesions with
normally functioning contralateral sinus.
Study design: Retrospective case study of laterally placed
posterior table CSF leak and frontal mucocele were evaluated
for their clinical presentation, radiological, operative findings
and follow-up.
Conclusion: Complete external approaches to the lateral
lesion of FS are associated with high morbidity. Ability of the
endoscopes to visualize lateral and posterior extents of the
FS directly through the brow incision helps in complete repair/
excision of these lesions without any difficulty.
