After the injection of a local anesthetic agent, an incision was made on the patient’s right side at the site of the medical canthal tendon. After careful dissection, the lacrimal sac was identified and removed. _____________________________________

Using the punch biopsy method, a specimen was taken from the right external auditory canal. ___________________________________
A patient presented with a fistula of the left salivary gland. This area was incised to expose the fistula, and the operating microscope was used to get better view of the fistula for the purpose of closure. ____________________________________

The scenarios describe medical procedures on the lacrimal sac related to the nasolacrimal duct, a punch biopsy of the external auditory canal, and fistula repair in the salivary gland, all of which are related to human anatomy and surgical practice.

The provided scenarios describe various medical procedures involving structures related to the eye and ear, which pertain to the field of medicine, more specifically to anatomy and surgical techniques. In the first scenario, an incision near the medial canthus to access the lacrimal sac, which is part of the lacrimal apparatus, is described. The lacrimal sac is a tear reservoir that drains into the nasolacrimal duct leading to the nasal cavity. This structure is crucial for tear drainage, maintaining a moist surface of the eye. The second scenario refers to a punch biopsy taken from the right external auditory canal, which is a procedure to extract a tissue sample for diagnostic purposes. Lastly, the incision of a fistula in the left salivary gland indicates a surgical approach to treat an abnormal connection that requires closure, often using a specialized operating microscope for enhanced visualization.
