The current accepted treatment for chronic frontal sinus disease unresponsive to medical management and endoscopic surgery is an external approach to either obliterate the sinus or restore communication to the nasal cavity. Here reported is an endoscopic approach for resection of the intranasal frontal sinus floor, a modification of a procedure first described by Lothrop in 1899. Eleven patients underwent this operation from April 1993 to December 1993. One complication, a cerebrospinal fluid leak treated successfully endoscopically, has occurred. Of the 7 patients followed up 3 months or longer after surgery, only 1 has developed symptoms of recurrent frontal sinusitis. On the basis of this limited preliminary experience, the endoscopic Lothrop procedure shows promise as an effective operation designed to establish a physiologic communication between the frontal sinus and the nasal cavity in selected patients who would otherwise be candidates for an external approach.
