A Short Term Subjective and Objective Analysis of Modified Endoscopic Lothrop's Procedure and Its Functional Outcome: Our Experience.

Abstract

To study the short-term functional outcomes of the endoscopic modified Lothrop procedure with well defined subjective and objective criteria. It's a retrospective cohort study with chart review carried out at a tertiary referral center. 31 patients with chronic frontal sinusitis who underwent endoscopic modified Lothrop's procedure with uncinate preservation during the period Jan 2011-2014 were followed up for a period of minimum 6months. Assessment was done post-operatively based on subjective severity score and Kennedy's 5 point endoscopic criteria. Subjective improvement was seen in all symptoms whereas statistically significant improvement was found for the three parameters headache (p<0.025), nose block (p<0.03) and rhinorrhea (p<0.05). Post operative nasal endoscopy revealed crusting and polypoidal mucosa in few patients which were managed conservatively. Asymptomatic narrowing of ostium seen in two patients. No complications were identified. The study illustrates the benefit obtained from endoscopic modified Lothrop's surgery in chronic frontal sinusitis refractory to medical treatment and standard endoscopic sinus surgery.
