Introduction: The objective components of chronic rhinosinusitis (CRS) diagnosis require confirmatory findings from either diagnostic nasal endoscopy (DNE) or a computed tomography (CT) scan. Chronic rhinosinusitis affects a significant population worldwide, imposing a huge toll on the human economy as well as on quality of life. Thus, it is particularly important to define a cost-effective and easily available diagnostic tool for it. Hence, we have conducted this study with the aim of assessing the effectiveness of DNE in comparison with CT for evaluating CRS. Material and Methods: Eighty participants fulfilling the diagnostic symptom criteria of CRS underwent CTs of their noses and paranasal sinuses (PNS) and DNE. Standard Lund–Mackay and Lund–Kennedy scores were awarded to all participants based on the CT and DNE. A comparative analysis was done. Results: DNE in comparison to CT had 92.31% sensitivity, 73.33% specificity, 93.75% positive predictive value, 68.75% negative predictive value, and 88.75% diagnostic accuracy. Conclusion: We suggest that nasal endoscopy be used as an early diagnostic tool in the clinical assessment of suspected CRS patients (based on the diagnostic symptom criteria). DNE helps to decrease the usage of CT, thereby decreasing cost and radiation exposure. Computed tomography may be added for patients having anatomical defects (affecting endoscopic visualization) or refractory disease, and where surgery has been planned.
To demonstrate the surgical technique and outcomes of double posterior based flap technique in primary endoscopic dacryocystorhinostomy (DCR) with and without use of powered instrument. 28 patients of nasolacrimal duct obstruction were included in the study from September 2012 to February 2015. All underwent endoscopic dacryocystorhinostomy with double posterior based nasal and lacrimal flap technique. In patients of group A (14 patients), bone removal was done with the help of Smith-Kerrison punch forceps and in patients of group B (14 patients), powered drill has been used for the same. Patients were visited the endoscopic clinic at 1, 3, 6 months and 1 year after the surgery for post operative evaluation. Of 28 patients, 26(92.85%) were found free of symptoms at the end of 1, 3 and at 6 months. One from each group had recurrence of symptoms. At the end of 12 months of 25 patients, 3(12%) patients were found to have recurrence of symptoms of which 1(8.33%) patients was from group A and 2(15.38%) were from group B and failures were because of granulation tissue and stomal stenosis. Patients assisted with powered drill had more postoperative complications compared to cold instrument. Double posterior based flap technique in primary endoscopic DCR without the assistance of powered drill could be an effective surgical option for the patients of chronic nasolacrimal duct obstruction enabling early epithelisation by preventing peristomal granulation tissue resulting in encouraging surgical outcome with least postoperative complication.
Cerebrospinal fluid Rhinorrhoea is caused by an abnormal open communication between the subarachnoid space and the nasal cavity. The most common anatomic sites of such abnormal communication are found in the anterior skull base, namely, ethmoid roof, olfactory groove, roof of the sphenoid sinus and the posterior wall of the frontal sinus. It can be classified into traumatic or spontaneous. Spontaneous leaks are associated with highest recurrence rates following surgical repair. The repair of CSF Rhinorrhoea has rapidly evolved over the past 30 years. Prior to the advent of the endoscopic approach, craniotomy was used for repairs which carried a variable success rate and morbidity. The purpose of our study was to ascertain the outcome after Transnasal Endoscopic Repair of spontaneous CSF leaks. This was a prospective study conducted at the Department of ENT at Safdarjung Hospital, New Delhi between January 2015 and June 2016. The study comprised of eleven patients who presented with the complaint of watery nasal discharge and were diagnosed to have spontaneous CSF Rhinorrhoea. Proper clinical examination, nasal endoscopy and biochemical and cytological analysis of nasal secretions of the patient was done. High Resolution Computed Tomography and MRI scans of the nose and paranasal sinuses were done to identify precise location of CSF leak and the size of fistula. CT cisternography was done wherever required. Fistula was repaired via Transnasal endoscopic approach in a multi layered underlay fashion. Out of all eleven patients with spontaneous CSF leaks, most common site of leak was from left cribriform area. Four patients (36.36%) were found to have meningoencephalocele. No associated intracranial lesion was found and all patients did not have any benign intracranial hypertension. Our success rate of endoscopic repair on first attempt was 100% with recurrence in 1 patient after 4 months of repair. Endoscopic repair of CSF rhinorrhoea is safe and effective, with a very low complication rate. It has almost completely replaced the older open techniques. Accurate localization of leak site followed by multilayered closure of dural defect appear to be essential for successful endoscopic repair.
