Abstract
A number of persons in other surgical disciplines express a blatant disregard for the potential dangers of frontal sinus mucosal entrapment. Although bone removal is universally recommended by the otolaryngologic proponents of ablative procedures in the frontal sinus, no comprehensive explanation has been proffered to justify this dictum.
