Platelet-rich plasma following endoscopic sinus surgery in patients with chronic sinusitis: A systematic review and meta-analysis of randomised controlled trials.

Introduction: To comprehensively evaluate the reported clinical effectiveness of platelet-rich plasma (PRP) in patients with chronic sinusitis undergoing endoscopic sinus surgery (ESS).

Methods: We performed a systematic review and meta-analysis of randomised controlled trials (RCTs). Five digital online databases (PubMed, Scopus, Web of Science, Google Scholar and Cochrane CENTRAL) were searched from inception up to 1st May 2023.

Efficacy of perioperative lidocaine infusion on surgical field quality during functional endoscopic sinus surgery: a systematic review and meta-analysis with trial sequential analysis.

Purpose: To perform a systematic review and meta-analysis of randomized controlled trials (RCTs) that assessed the efficacy of perioperative intravenous lidocaine versus placebo in improving the quality of surgical field during functional endoscopic sinus surgery (FESS).

Methods: PubMed, Scopus, Web of Science, and CENTRAL were thoroughly searched from inception until June 2023. The included RCTs were evaluated via RoB-2 tool.

Surgical Instructions in Revision Endoscopic Sinus Surgery: Pearls and Pitfalls.

Functional endoscopic sinus surgery (FESS) has become one of the most common surgical techniques performed by otolaryngologists with significant data demonstrating its efficacy in managing patients with chronic rhinosinusitis (CRS). However, despite this initial success, patients may continue to present with recurrent symptoms and approximately 10-15% of them will require revision surgery. Failure of FESS may have many different causes which include inappropriate patient selection and preparation, comorbidities like cystic fibrosis and Samter's triad, insufficient surgical skills or anatomical variations that have not been addressed adequately.

Maxillary Odontogenic Keratocyst.

The Odontogenic Keratocyst (OKC) is one of the most aggressive odontogenic cysts. OKCs of the maxilla are particularly rare with less than 1% of cases reported in the literature. A 29-year-old female patient presented with pain and loose upper molars.

Nasal-type extranodal NK/T-cell lymphoma presenting as recurrent periorbital cellulitis.

Nasal-type extranodal natural killer/T-cell lymphoma (ENKTCL) is a rare disease with a poor prognosis. It has features similar to other granulomatous and infectious diseases of the nose and paranasal sinuses, which can make diagnosis challenging and delayed. We present a case of 38-year-old man who was admitted to the hospital on three occasions over a 3-month period for right periorbital erythema, nasal congestion and discharge.

Use of the pedicled nasoseptal flap in the endoscopic management of cholesterol granulomas of the petrous apex.

Background: Nowadays the endoscopic approach represents a useful alternative to traditional surgical approaches in the treatment of cholesterol granulomas (CGs) of the petrous apex (PA). Recently the nasoseptal flap (NSF) has been employed to permit long-term patency of drainage site. The purpose of this study is to report our experience with the NSF in the endoscopic management of CG and to analyze the advantages, limitations, and outcomes of the technique.

Newly designed double-vascularized nasoseptal flap to prevent restenosis after endoscopic modified Lothrop procedure (Draf III): laboratory investigation.

Despite advances in endoscopic approaches, instrumentations and imaging guidance systems, the management of frontal sinus is still challenging. Failure of the endoscopic procedure and restenosis of the newly formed ostium have been demonstrated even with large frontal sinusotomy. We describe a newly designed double nasoseptal flap to cover the bare bone after endoscopic modified Lothrop procedure (EMLP).
