In the present study the sphenoethmoid
suture showed early signs of fusion (grade 2) at a mean age of 4 years in 176 cases (88%), and reached complete fusion at a mean age of 12 years.
The pedicle of the polyp was traced to the left sphenoid ostium in the sphenoethmoid
The PCR assay, however, was positive for H pylori at both the sphenoethmoid
recess and the intrasinus sites (table).
Swab specimens of the middle meatus and the sphenoethmoid
recess were collected under endoscopic vision without touching the nasal vestibule and mucosa.
The sphenoid sinus ostium is usually located in the sphenoethmoid
recess between the superior turbinate and the nasal septum.
Awareness of the presence of an Onodi cell or multiple Onodi cells is important prior to dissection in the sphenoethmoid
area (7) The sphenoid sinus is normally situated behind the posterior end of the posterior ethmoid sinus.
On the medial side of the inferior insertion of the supreme turbinate, a slit-like ostium of the sphenoid sinus in the right sphenoethmoid
recess was seen.
Our aims were to determine the prevalence of an Onodi cell in adult Thai cadavers, to ascertain the prevalence of an overriding ethmoid cell, and to measure the length of an overriding sphenoethmoid
cell's superior and posterior extensions in relation to the anterior sphenoid wall.
Cadaveric studies have shown a highly variable anatomy in the relationship of the optic nerve to the posterior sphenoethmoid
Polyps arise in various parts of the nasal cavity, including the uncinate process, the ethmoid infundibulum, the ethmoid bulla, the frontal recess, the sphenoethmoid
recess, the superior meatus, the middle turbinate, and the superior meatus.
