Abstract
Introduction: Functional endoscopic sinus surgery (FESS) is the most commonly used surgical technique to treat medically unresponsive chronic sinusitis and other serious conditions of the nasal sinuses that result in impaired sinus drainage. FESS utilizes small fiberoptic tools to approach the nasal sinuses through the anterior nasal nares to remove diseased tissues and bones, resulting in opened sinus passageways, improved mucus drainage and promotion of healthy tissue growth.
Aim of the Work: In this study we aim at evaluating the effect of lidocaine-soaked nasal packing on postoperative pain for patients undergoing ESS for refractory chronic rhinosinusitis.
Methodology: The study is a prospective, randomized, single blinded trial of seventy adult patients who underwent elective functional endoscopic sinus surgery(FESS) for chronic sinusitis without nasal polyposis or chronic sinusitis with nasal polyposis refractory to appropriate medical treatment at Ain-shams university hospitals from January 2017 to May 2017.
Results: group A: (35 patients) included patients with anterior nasal packs (merocel) following FESS. Packs are soaked with 2 cm lidocaine (2%) which is repeatedly applied by using a syringe every 12 hours for two days. group B: (35 patients) included patients with anterior nasal packs (merocel) following FESS. Packs are soaked with 2 cm saline which is repeatedly applied by using a syringe every 12 hours for two days.
Conclusion: Therefore, we conclude that the application of lidocaine on nasal packs after FESS might be safe and it has a role in pain relief postoperatively especially at pack removal and it should be considered to use.
Recommendations: To achieve maximal clinical benefit without major side effects further investigation of lidocaine plasma concentrations to be measured to evaluate the systemic absorption of topical lidocaine will be needed to reach the maximal benefits.
