Final answer:
The patient underwent unilateral nasal endoscopy, partial ethmoidectomy, and maxillary antrostomy in the surgical unit.
Step-by-step explanation:
In the surgical unit, the patient underwent several procedures:
- Unilateral nasal endoscopy: This involves inserting a thin, flexible tube with a light and camera into one nostril to examine the nasal passages and sinuses.
- Partial ethmoidectomy: This is a surgical procedure to remove a portion of the ethmoid bone, which is located in the central skull and forms part of the nasal cavity.
- Maxillary antrostomy: This is a procedure to create an opening in the maxillary sinus, which is located below the orbit, to improve drainage and reduce sinus inflammation.
Therefore, the correct answer is 4) All of the above.
