This procedure allows the doctor to examine the nasal passages and sinuses closely. Using a small instrument called an endoscope, inserted gently through the nose, the doctor can look for signs of infection, nasal polyps, tumors, or structural abnormalities. It is especially helpful for people with chronic sinus problems or unexplained nasal blockage.

The procedure is usually done while you are awake. A numbing spray may be used in the nose to reduce discomfort. Patients can go back to normal activities right away. There is no effect on speech or breathing after this procedure. Occasionally, mild nosebleeds or irritation can occur, but these are rare. The procedure helps guide further treatment, such as surgery, medication, or allergy care.

Diagnostic esophagoscopy is a procedure used to look inside the esophagus, which carries food from the mouth to the stomach. It is used to diagnose the causes of swallowing difficulty, pain, or suspected tumors or strictures in the esophagus. The doctor uses a long, flexible tube with a light and camera to inspect the esophagus.

Depending on the patient's condition, the procedure may be done with mild sedation or general anesthesia. Sometimes, it can be done in the office setting. It is generally safe and does not affect speech. After the procedure, your throat might feel sore, and you may need to avoid eating or drinking for a short period. Any findings may require a biopsy, and depending on the results, follow-up may include dietary changes, medications, or additional treatments.

This procedure combines two techniques—dilation to widen narrowed airways and excision to remove abnormal tissue. It is often performed in patients with airway stenosis, tumors, or inflammatory lesions that are blocking normal airflow. This approach helps restore breathing and can reduce coughing, wheezing, or noisy breathing.

Diagnostic Bronchoscopy can sometimes be done in the office with local anesthesia.

Bronchoscopy is performed under general anesthesia. A bronchoscope is used to access the airway. A balloon or rigid dilator is inflated to widen the narrowed section, and surgical instruments or a laser may be used to remove excess tissue. Afterward, patients are monitored for breathing and airway swelling. Voice is usually unaffected unless the lesion is near the vocal cords. Multiple treatments may be necessary in chronic cases, and follow-up often includes imaging or repeat scoping to ensure long-term airway patency.
