Area of Science:

  • Otolaryngology
  • Endoscopic Sinus Surgery

Background:

  • The traditional Lothrop procedure, while effective, can lead to complications like soft tissue collapse and stenosis.
  • An external approach for frontal sinus surgery carries risks of medial collapse and nasofrontal communication stenosis.

Purpose of the Study:

  • To describe a modified transnasal endoscopic Lothrop procedure using drills.
  • To evaluate the safety, reliability, and efficacy of this modified approach in creating a wide frontonasal opening.

Main Methods:

  • A modified transnasal endoscopic Lothrop procedure was performed using drills.
  • The technique preserves lateral bony walls and mucosa of the posterior nasofrontal duct.
  • A single common frontal opening is created, avoiding medial collapse.

Main Results:

  • Fourteen patients underwent the modified procedure without complications.
  • All patients achieved resolution or improvement of symptoms.
  • Wide patency of the frontonasal opening was maintained.

Conclusions:

  • The modified transnasal endoscopic Lothrop procedure is a safe and reliable surgical option.
  • This technique effectively addresses frontal sinus obstruction while preventing complications associated with the external approach.
