OBJECTIVE: To describe a previously unreported case of repair of a lateral frontal sinus cerebrospinal fluid leak, using the endoscopic modified Lothrop procedure. METHOD: Case report of new technique, with reference to the world literature. RESULTS: An effective endoscopic, transnasal repair of a lateral frontal sinus cerebrospinal fluid leak was achieved in a 60-year-old man. The defect was closed with fat, fascia lata and free mucosal grafts. The left nasal cavity was packed and a lumbar drain left in situ post-operatively. The drain and packs were removed one week later and the patient discharged with no complications, and no recurrence at 12 months' follow up. CONCLUSION: Such cerebrospinal fluid leaks have traditionally been repaired using an external approach with osteoplastic flaps and obliteration of the sinus. We highlight the endoscopic modified Lothrop technique as an effective alternative approach to repair of cerebrospinal fluid leaks in poorly accessible areas of the frontal sinus.
