Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

4.5K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

838
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Epistaxis01:30

Epistaxis

683
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Pneumothorax-II01:27

Pneumothorax-II

1.3K
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Summary

Sinonasal cancer surveillance needs tailored follow-up, not just general head and neck cancer guidelines. Current methods like endoscopy and imaging have limitations in detecting recurrence post-treatment.

Area of Science:

  • Otolaryngology
  • Oncology
  • Radiology

Background:

  • Sinonasal neoplasms frequently recur after treatment.
  • Current surveillance follows general head and neck cancer guidelines.
  • A tailored approach to sinonasal cancer follow-up may be necessary.

Purpose of the Study:

  • To review current surveillance techniques for sinonasal neoplasms.
  • To evaluate the efficacy and limitations of various surveillance modalities.
  • To discuss the need for modified follow-up protocols.

Main Methods:

  • Review of current literature on sinonasal neoplasm surveillance.
  • Analysis of the performance of endoscopy and imaging techniques (CT, MRI, PET/CT).
  • Consideration of factors influencing surveillance effectiveness, such as post-treatment inflammation.

Main Results:

  • Endoscopy has low sensitivity for asymptomatic recurrence but can detect superficial recurrences.
  • Imaging techniques are useful for ruling out disease but are prone to false positives due to post-treatment inflammation.
  • PET/CT shows lower specificity and positive predictive value in sinonasal malignancy compared to overall head and neck malignancy.

Conclusions:

  • Sinonasal malignancy surveillance may require modifications to existing head and neck cancer protocols.
  • Greater diversity of sinonasal disorders and prolonged post-treatment inflammation necessitate adjusted follow-up.
  • Clinicians must understand surveillance technique performance to optimize patient follow-up regimens.
