ABSTRACT
Purpose: To study the endoscopic ostium characteristics and outcome of 8 × 8 mm osteotomy in external dacryocystorhinostomy (DCR) using the microdrill system. Methods: This prospective interventional pilot study was performed on 40 eyes of 40 patients with primary acquired nasolacrimal duct obstruction (NLDO) from June 2021 to September 2021 in patients undergoing external DCR. An 8 × 8 mm osteotomy was performed using round, cutting burr attached to a microdrill system. Success was defined as patent ostium on lacrimal syringing (anatomical) and a Munk score <3 (functional) at 12 months. Postoperative endoscopic ostium evaluation was done using a modified DCR ostium (DOS) scoring system at 12 months. Results: The mean age of the study participants was 42.41 ± 11.77 years and the male?to?female ratio was 1:4. The mean duration of surgery was 34.15 ± 1.66 minutes and that for osteotomy creation was 2.5 ± 0.69 minutes. The mean intraoperative blood loss was 83.37 ± 11.89 ml. Anatomical and functional success rates were 95% and 85%, respectively. The mean modified DOS score was “excellent” in 34 patients (85%), “good” in 1 patient (2.5%), “fair” in 4 patients (10%), and “poor” in 1 patient (2.5%). Complications included nasal mucosal injury in 10% (4/40) of patients, complete cicatricial closure of ostium in 2.5% (1/40), incomplete cicatricial closure in 10% (4/40), nasal synechiae in 5% (2/40), and canalicular stenosis in 2.5% (1/40). Conclusion: An 8 × 8 mm–sized osteotomy created by powered drill and covered by lacrimal sac–nasal mucosal flap anastomosis in external DCR is an effective technique that has minimal complications and shorter surgical time
ABSTRACT
Abstract Introduction The role of endoscopes in the ear, nose, and throat (ENT) field has been described since the 1980s; It started with endoscopic nasal surgeries, followed by otological and laryngological procedures, and, since then, it has experienced a rapid evolution. Endoscopes help otologists understand how to approach difficult areas of middle ear, as well as the physiology of middle ear cleft. Objectives Despite the introduction of endoscopes in the field of otology, microscopes are still widely used in clinics and in operation theaters either alone or with endoscopes. The present study, which was conducted amongst otologists in India, is on their experience with and knowledge of the use of the endoscope compared to microscopes. Methods A Google form-based questionnaire comprising 18 questions was developed and sent online to otologist all over the country. The final dataset included responses from 354 active otologists. Results Out of 354 participants, only 3% had more than 5 years of experience in endoscopic ear surgery (EES), and 16.1% had never worked with an endoscope. Endoscopes were used in clinics and in operation theaters by 74.9% of the participants. Conclusion There has been a rise in the acceptance and use of endoscopes among Indian otologists and otology surgeons in last few decades.
ABSTRACT
OBJETIVO: Comparar uma técnica composta de dacriocistorrinotomia (DCR) endoscópica à técnica convencional. MÉTODO: Foi realizado um estudo prospectivo no Departamento de Otorrinolaringologia da Faculdade de Medicina Maulana Azad. Trinta pacientes selecionados para DCR endoscópica foram divididos em dois grupos, um submetido à DCR endoscópica convencional e outro tratado com uma técnica mais nova com o uso de cautere, instrumentação fria e laser em diferentes etapas da DCR endoscópica. Os pacientes foram seguidos por nove meses. RESULTADOS/CONCLUSÃO: Com o uso do cautere, instrumentação fria e laser em diferentes etapas da DCR endoscópica, fomos capazes de obter taxa de sucesso de cerca de 94% com a técnica composta em comparação a 83,3% da DCR endoscópica convencional.
AIM: To compare a composite technique of Endoscopic Dacrocystorhinostomy with the conventional technique. METHODS: A randomised prospective study was carried in the department of Otolaryngology Maulana Azad Medical College. Thirty patient selected for Endoscopic DCR were divided into two groups, one of which underwent conventional Endoscopic DCR and the other group were treated with a newer technique using cautery, cold instrumentation and laser at different steps of Endoscopic DCR. The patients were followed up for Nine months. RESULTS/CONCLUSION: By using cautery, cold instrumentation and laser at different steps of Endoscopic DCR we were able to achieve a success rate of around 94% with this composite technique as compared to 83.3% in conventional Endoscopic DCR surgery.
