Background: Laryngoscopy is a visual examination of the larynx and its related structures. It is an effective procedure for ascertaining the causes of laryngeal disorders, pain in the throat and difficulty in swallowing.
Aim and Objective: This study establishes the use of laryngoscopy in otolaryngology clinics in PH. It will also bring to limelight its use. Finally, it will analyze the indications and the role it played in the management.
Patients and Methods: This was a 2 years (January 2013 to December 2014) prospective study of 202 laryngoscopy procedures done in the Ear, Nose and Throat (ENT) surgery clinics of University of Port Harcourt Teaching Hospital (UPTH) Port Harcourt and Kinx Medical Consultants clinic in Port Harcourt. All laryngoscopies done were documented by the researchers in a profoma prepared for the study. The data collected were bio-data (age and sex), presenting symptoms/indications for the procedure, types of laryngoscopy, findings at laryngoscopy/biopsy results. The data were entered into an SPSS version 14 computer software and analyzed descriptively.
Results: There were 60 males and 142 females with a M: F ratio of 1:2.4. age range was 18-83 years with a mean of (54.5 ± 5.64). Age group 40-50 years had the highest number of procedures. The commonest type done was indirect laryngoscopy. The commonest indication was pre-operative evaluation for thyroidectomy. The commonest positive finding was hyperaemia and indurations in 25 cases.
Conclusion: Laryngoscopy remains a very useful cost effective diagnostic and therapeutic procedure especially when carried out in the clinic as outpatient procedure.
