After removal of nasal packing following epistaxis, routine nasoendoscopy is not necessarily indicated. [3] However, widely accepted indications for nasoendoscopy include: [ 4 ] abnormal speech characteristics: hypernasal resonance, excessive nasal airflow including nasal air escape and nasal turbulence (also called nasal rustle), and absence ...
The endoscopic approach to FESS is a less invasive method than open sinus surgery, which allows patients to be more comfortable during and after the procedure. Entering the surgical field via the nose, rather than through an incision in the mouth as in the previous Caldwell-Luc method, decreases risk of damaging nerves which innervate the teeth ...
Some polyps may be seen with anterior rhinoscopy (looking in the nose with a nasal speculum and a light), but frequently, they are farther back in the nose and must be seen by nasal endoscopy. [12] Nasal endoscopy involves passing a small, rigid camera with a light source into the nose. An image is projected onto a screen in the office so the ...
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.
Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.
A turbinectomy or turbinoplasty (preserving the mucosal layer) is a surgical procedure, that removes tissue, and sometimes bone, of the turbinates in the nasal passage, particularly the inferior nasal concha. The procedure is usually performed to relieve nasal obstructions. [1]
On a CT scan, acute sinus secretions have a radiodensity of 10 to 25 Hounsfield units (HU), but in a more chronic state they become more viscous, with a radiodensity of 30 to 60 HU. [67] Nasal endoscopy and clinical symptoms are also used to make a positive diagnosis. [28] A tissue sample for histology and cultures can also be collected and ...
The sinus will fill with fluid or blood unless the pressure differential is neutralized. [6] If the outlet is blocked during ascent, the situation is reversed and "reverse squeeze" appears. [7] Pressure inside the sinus increases, affecting the walls of the sinus and producing pain or epistaxis.
