Osteoplastic flap versus modified endoscopic Lothrop procedure in patientswith frontal sinus disease

The aim of the present study was to review the clinical results of osteopla stic flap procedure with abdominal fat obliteration and modified endoscopic Lothrop procedure. Charts of patients with frontal sinus disease who under went osteoplastic flap procedure with abdominal fat obliteration or modifie d endoscopic Lothrop procedure were retrospectively reviewed Forty-three pa tients with frontal sinus disease underwent osteoplastic flap procedure wit h abdominal fat obliteration. Frontal sinus disease was chronic sinusitis i n 21, mucocele in 18, and papilloma ir? four: None of the patients had recu rrence within 3 to 12 years follow-up period. Six patients had decreased fo rehead sensation, one had a CSF leak, and one had loss of the fat graft. Fi fteen patients with chronic frontal sinusitis underwent monified endoscopic Lothrop procedure. The follow-up period ranged from 0.5 to 2.5 years. Two patients had recurrence of disease 2 and 6 months after surgery and require d osteoplastic flap. In patients with chronic frontal sinusitis, both proce dures achieved good relief of symptoms; however, follow-up time of modified endoscopic Lothrop procedure Ir,as smaller than that of osteoplastic flap procedure. In conclusion, osteoplastic flap procedure with abdominal fat ob literation provides successful treatment in patients with frontal chronic s inusitis, mucocele, or papilloma. Modified endoscopic Lothrop procedure ach ieves the relief of symptoms in patients with chronic frontal sinusitis. Wi th the future availability of long term follow-up results, modified endosco pic Lothrop procedure may reduce the number of osteoplastic flap procedure in patients with chronic frontal sinusitis.
