BACKGROUND: Endoscopic Modified Lothrop Procedure (EMLP) has become a fundamental practice in rhinology. Improvements in symptom burden, ostial patency, morbidity, and costs have surpassed that of an open approach to the frontal sinus. Long-term efficacy has not been well established.
OBJECTIVE: This study details the long-term outcomes of EMLP and risk factors for subsequent surgical revision at a single institution.
METHODS: This study utilized a retrospective review of patients who underwent EMLP from September 2006 to February 2017 by a single surgeon at an academic tertiary referral center. Patient demographics, indications, symptom burden, and endoscopic assessment of frontal ostium patency were analyzed for their effect on surgical outcome. Risk factors for failures were identified.
RESULTS: Seventy-six consecutive patients with an average age of 58.1 years met the inclusion and exclusion criteria and underwent EMLP for chronic rhinosinusitis (CRS, 59%), neoplasm (26%), and mucoceles (15%). The average number of standard endoscopic sinus surgeries prior to EMLP was 2.9. The mean follow-up of the cohort was 34.8 months, at the end of which, EMLP was successful in 78% of all patients, requiring no further surgery. Ninety percent of patients reported significant clinical improvement at the most recent follow-up. Subgroup analysis of CRS patients revealed an equally high success rate but a higher likelihood of ostial closure. Recurrent disease necessitated revision endoscopic surgery in 17 patients, the majority of whom suffered CRS. Only tissue eosinophilia was identified to significantly increase the risk of revision surgery.
CONCLUSIONS: The majority of the patients who undergo EMLP achieve sustained patency of the frontal sinus outflow tract and adequate symptom improvement. Prominent tissue eosinophilia identifies patients at risk of requiring additional frontal sinus surgery.
LEVEL OF EVIDENCE: 4.
