Epistaxis01:30

Epistaxis

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...
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

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.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Head and Neck Surgery

Background:

  • The nasoseptal flap is integral to endoscopic endonasal cranial base surgery.
  • Its vascular supply originates from the sphenopalatine artery via the posterior septal artery.
  • It serves as an effective barrier against cerebrospinal fluid (CSF) leaks.

Purpose of the Study:

  • To provide a comprehensive review of the nasoseptal flap in endoscopic endonasal surgery.
  • To detail the harvesting, reconstruction, and modification techniques.
  • To discuss potential complications associated with the flap.

Main Methods:

  • Review of surgical techniques for nasoseptal flap harvesting and reconstruction.
  • Analysis of flap versatility and coverage of cranial base defects.
  • Discussion of vascular pedicle and healing properties.

Main Results:

  • The nasoseptal flap significantly reduces postoperative CSF leak risk to under 5% for large defects.
  • Its reliable vascular supply ensures rapid healing.
  • The flap offers a wide arc of rotation, enabling coverage from the frontal sinus to the lower clivus.

Conclusions:

  • The nasoseptal flap is a versatile and reliable option for skull base reconstruction.
  • It plays a vital role in minimizing CSF leak complications in endoscopic endonasal surgery.
  • Understanding its techniques and potential complications is essential for optimal patient outcomes.
