[ 1 ] - Evaluating the Effect of Endoscopic Sinus Surgery on Laryngeal Mucosa Stroboscopic Features

Introduction: The major presenting symptom of nasal polyps is nasal obstruction. The role of nasal obstruction in the genesis of laryngeal disorders is still unknown.   Materials and Methods: The aim of this study was to evaluate laryngeal videostroboscopic changes after functional endoscopic sinus surgery (FESS) in patients with nasal polyposis. A longitudinal study was carried out from M...

[ 2 ] - Rate of Occult Cervical Lymph Node Involvement in Supraglottic Squamous Cell Carcinoma

Introduction: To assess the rate of cervical lymph node involvement in patients with supraglottic squamous cell carcinoma (SCC) with no lymph node in clinical assessments and radiological studies. Materials and Methods: Fifty-six patients who underwent elective dissection of the cervical lymph node of the second through fourth level were enrolled, and pathologic evaluation of the dissected lymp...

[ 3 ] - DETERMINATION OF THE PREVALENCE OF OCCULT NECK LYMPH NODE INVOLVEMENT IN PATIENTS WITH LARYNGEAL SQUAMOUS CELL CARCINOMA

Background & Aims: Squamous cell carcinoma (SCC) accounts for 85% of laryngeal cancers. In some cases, lymph nodes do not show any specific symptoms despite being involved by cancer. Previous studies showed that patients undergoing selective neck lymph node dissection (SND) had significantly lower recurrence rates. We investigated the prevalence of occult neck lymph node involvement in patients...
