This process is a method to detect the frontal sinus outflow tract. In some cases after endoscopic sinus surgery, frontal sinus trephining is indicated in order to prevent stenosis of frontal sinus infundibulum by passing down a catheter into the frontal recess. Following endoscopic frontal sinus surgery, frontal sinus trephination can be used ...
Endoscopic endonasal surgery is a minimally invasive technique used mainly in neurosurgery and otolaryngology.A neurosurgeon or an otolaryngologist, using an endoscope that is entered through the nose, fixes or removes brain defects or tumors in the anterior skull base.

Since 2015, two developments have enhanced our understanding of the anatomy of the eustachian tube: Valsalva computerized tomography and endoscopic ear surgery. [ 11 ] Given the greater access to the ear anatomy using endoscopic methods, it has been suggested that the bony part of the eustachian tube is really the anterior extension of the ...
At birth, only the maxillary sinus and the ethmoid sinus are developed but not yet pneumatized; only by the age of seven are they fully aerated. The sphenoid sinus appears at the age of three, and the frontal sinuses first appear at the age of six, and fully develop during adulthood. [5]
Persons with dry eye conditions can be fitted with punctal plugs that seal the ducts to limit the amount of fluid drainage and retain moisture. During an ear infection, excess mucus may drain through the nasolacrimal duct in the opposite way tears drain. [citation needed] In humans, the tear ducts in males tend to be larger than the ones in ...
