Outcomes of the modified endoscopic Lothrop procedure.
BACKGROUND
The aim of this study was to examine the long-term outcomes of the modified endoscopic Lothrop procedure for the management of the most severe forms of recalcitrant chronic frontal sinusitis.


METHODS
This case series evaluated 13 consecutive cases of the modified endoscopic Lothrop procedure for chronic frontal sinusitis from April 1996 to December 1999. Patent communication to the frontal sinus was evaluated by postoperative endoscopic exam. Postoperative patient symptomatology and medication requirements were assessed during clinic evaluation and by standardized telephone questionnaire.


RESULTS
At a mean follow-up period of 34.5 months, a 77% patency rate was obtained, with 2 of the 13 patients requiring an osteoplastic flap with obliteration. Telephone questionnaire results indicate improved symptoms and decreased medication requirements in the majority of patients who maintained patency.


CONCLUSIONS
These results show that the modified endoscopic Lothrop procedure provides a good alternative to the osteoplastic flap with obliteration for patients with the most severe forms of chronic frontal sinusitis. Initially, high patency rates decline with longer-term follow-up, and severe forms of chronic rhinosinusitis continue to significantly impact patient-perceived quality of life in some patients. The modified endoscopic Lothrop procedure should be reserved for patients who have failed more conservative endoscopic approaches to the frontal recess.
