Background: Flexible laryngoscopy is less operator/patient dependent diagnostic procedure with magnified field and well tolerated diagnostic procedure. Flexible laryngoscopy is tolerable diagnostic procedure with clear and magnified visualization of interior larynx. Aim: To audit the flexible laryngoscope in outpatient department in our local setting. Methods: A retrospective audit survey was carried out in Outpatient ENT Department of Akbar Niazi Teaching Hospital, Islamabad between June 2021 and May 2022. Total 85 patients with age range 10-80 years, with history of laryngopharyngeal symptoms and preoperative evaluation of thyroidectomy patients were selected. After getting detail history of flexible naso-pharyngo-laryngoscopy and findings were documented and analyzed. Under local anesthesia, spray in the nose and throat gargles. The laryngoscope passed through nose and nasopharynx into the laryngopharynx, and assessing all the structures. Data was analyzed through SPSS v 22. Results: The patients mean age was 28.96±9.14 years. Among all the patients 49(57.64%) were female and 36(42.3%) were male. The population highest percentage 26(30.5%) were 21-30 years old. The laryngeal complaint of hoarseness was highest with 38.8% indicated after flexible laryngoscope procedure according to other symptoms. According to diagnosis made on flexible laryngoscopy, the vocal nodules were highest with 15.3% detected. The diagnostic tools in diagnosis of laryngeal pathologies, its availability and cost effectiveness led to limited access of the patients to such sophisticated diagnostic procedure. Conclusion: Flexible laryngoscopy gives detailed visualization of the larynx and don’t leave the examiner inconclusive about laryngeal pathologies.

“…In contrary to this, a retrospective study was conducted by Omokanye et al to determine the diagnostic efficacy of flexible laryngoscope in 360 patients and was compared with DL. The results showed that the diagnostic accuracy was comparable to DL and is more statistically significant when compared to the above mentioned studies [17]. Thus, the usage of flexible laryngoscopy in OPD setting and DL in theater setting with anesthesia is more reasonable.…”

The management of all laryngeal pathologies begin with a simple and traditional examination with laryngeal mirror. Even though the use of mirror is invaluable, the image is often distorted and misleading in seven different ways. Direct laryngoscopy is a sermon on relaxation and does not require any local or general anesthesia in both children and adults. The greatest advantage of direct laryngoscopy is the presence of oblique illumination. This chapter deals with the different angulations of laryngeal mirrors and its seven drawbacks in detail. This also provides a detailed explanation of direct laryngoscopy technique in children and adults with its axioms and clinical application.

Background: Laryngotracheal stenosis is a common benign condition of airway obstruction in both the pediatric and adult age group. This could either be acquired or congenital, in which there is narrowing of either the portions of the larynx or trachea making it difficult to breathe. This condition can be managed by several operative and endoscopic procedures. Flexible fiber optic laryngoscope is an excellent tool in the diagnostic investigation of laryngotracheal stenosis. Methods: This is a retrospective study that was done with data collected from the medical records department of patients diagnosed with laryngotracheal stenosis in a tertiary care hospital in the last 10 years. Results: A total of 22 patients who underwent FFL exam were taken for this retrospective study and the results were analyzed. Conclusions: This study proves that Fiberoptic laryngoscopy is a single modality diagnostic tool, which is useful in diagnosing, and localizing stenotic lesions in the Laryngotracheal region. It is cheap, less invasive and trained Otolaryngologist can perform this as an outpatient procedure. This therefore reduces the exposure to harmful radiation caused by repeated computed tomography scans.
