    1. Aero-digestive Endoscopy Dr. Vishal Sharma

    2. History

    3. Bozzini (1806): angled speculum with mirror using wax candle, first examined larynx • Manuel Garcia (1854): Using dental mirror, hand mirror & sunlight visualized his own vocal cords • Adolph Kussmaul (1868): 1st rigid esophagoscopy • Gustav Killian (1897): 1st rigid bronchoscopy • Chevalier Jackson (early 1900s): father of modern rigid endoscopy • Oscar Kleinsasser (1960): suspension micro-laryngoscope • Shigeto Ikeda (1966): first fiberoptic bronchoscopy & oesophagoscopy • H.H. Hopkins: rigid fiberoptic telescopes

    4. Adolph Kussmaul

    5. Gustav Killian

    7. Shigeto Ikeda

    8. Direct Laryngoscopy

    9. Chevalier Jackson’s Direct Laryngoscope

    10. Anterior commissure Direct Laryngoscope

    11. Boyce’s Endoscopy position Supine position with head elevated by 10 cm

    12. Tongue Base visualized

    13. Epiglottis visualized

    14. Vocal cords visualized

    15. Micro-laryngoscopy

    16. Kleinsasser Microlaryngoscope

    17. Chest Piece

    18. Laryngoscope fixed

    19. Microscope focused

    20. Indications for Laryngoscopy

    21. Diagnostic Therapeutic  Biopsy of suspected malignancy  Foreign body in larynx & pyriform fossa removal (larynx & pyriform fossa)  Examination of hidden areas:  Excision biopsy anterior commissure, laryngeal of benign ventricle, subglottis, infrahyoid laryngeal lesion epiglottis, pyriform fossa apex  Dilatation of laryngeal stricture  Unsuccessful indirect laryngoscopy

    22. Rigid Bronchoscopy

    23. Rigid Bronchoscope

    24. Close-up of proximal end

    25. Bronchoscope introduced

    26. At laryngeal inlet

    27. Epiglottis identified

    28. Vocal cords identified

    29. Scope passed through glottis after 900 rotation

    30. Scope rotated back

    31. Tracheal rings identified

    32. Carina identified

    33. Bronchopulmonary segments

    34. Endoscopy position

    35. Scope in Right bronchus

    37. Scope in Right bronchus

    38. Scope in Left bronchus

    39. Scope in Left bronchus

    40. Scope in Left bronchus

    41. Flexible Bronchoscope

    42. Indications for Bronchoscopy • Broncho-alveolar lavage for C/S, AFB, cytology • Biopsy of tracheo-bronchial tumours • Investigation of chronic cough, hemoptysis, Lt vocal cord palsy, atelectasis, obstructive emphysema, mediastinal growths • Removal tracheo-bronchial of foreign bodies • Removal of retained respiratory secretions

    43. Rigid Oesophagoscopy

    44. Rigid Oesophagoscope

    45. Epiglottis visualized

    46. Right pyriform fossa

    47. Cricopharyngeal sphincter
