The frontal sinus surgery is difficult to perform but the ethmoid bulla is a relative, constant landmark in the middle turbinate that can improve the surgery. The purpose of this study was to evaluate the validity, security, and predominance of approaches to the frontal sinus via the route anterior to the ethmoid bulla. The data from 370 endoscopic frontal sinus surgery cases from our center were integrated and retrospectively analyzed. Three hundred twenty-nine patients underwent frontal sinus surgery via the route anterior to the ethmoid bulla. An additional 27 patients underwent frontal sinus surgery with mini-trephination, 13 patients with the Draf II procedure, and 1 patient had applied MELP (modified endoscopic Lothrop procedure). No serious complications occurred; however, there were 3 cases of eyelid ecchymosis and 1 case of anterior ethmoid artery bleeding. In all, 319 patients (86.2%) were cured, an improvement was noted in 36 of the patients (9.7%), and there was no improvement in 15 patients (4.1%). Frontal sinus surgery via the route anterior to the ethmoid bulla is valid, relatively safe, and can be applied in most cases involving frontal disease.

“…It might be single or multiple and might open into the lateral aspect of the frontal recess 2. On coronal CT images, SOECs are found lateral to the frontal sinus, whereas the FBCs are medial to it 8. In a study of SOECs in 57 Korean and 41 white subjects, Cho et al7 found that SOECs were more frequent in the white population (64.6%) than in the Korean population (2.6%).…”

“…Computed tomography (CT) is an invaluable adjunct to diagnostic nasal endoscopy in identifying various causes of frontal recess obstruction. Many studies of frontal recess pneumatization patterns assessed by CT have been published, but only a few of them have focused on Asian adult populations 7–9. Anatomically, SBCs and FBCs occur posteriorly in the frontal recess along the skull base, and ANCs and FCs occur anteriorly in the frontal recess 2.…”

Computed tomographic analysis of frontal recess anatomy and its effect on the development of frontal sinusitis

et al. 2010

The frequency of frontal recess cells analyzed in Taiwanese adult patients was similar to that analyzed in other Asian adult populations (Chinese and Korean). The frontoethmoid cells posterior and posterolateral to the frontal recess (suprabullar cells, frontal bullar cells, and supraorbital ethmoid cells) might reveal a more significant association with the development of frontal sinusitis than those anterior to the frontal recess (agger nasi cells, frontal cell types 1-3). The presence of supraorbital ethmoid cells on computed tomographic images might indicate the highest odds of frontal sinusitis, followed by the presence of suprabullar cells, frontal bullar cells, and recessus terminalis.

Paranasal Sinuses

View full text Add to dashboard Cite

Paranasal sinuses located in the bones surrounding the nasal cavity are called maxillary, ethmoid, frontal and sphenoid sinuses. In relation with their location, these sinuses contribute to the development of the facial structures, jaws and upper airway. During the developmental process of the paranasal sinuses, anatomic variations can occur in consequence of intra and extramural migration of the ethmoid air cells, overpneumatization or hypoplasia of the sinuses and bulging of the neurovascular structures to the sinuses. Some of these anatomic variations may affect the drainage pathways, pave the way for chronic infections and cause difficulties when performing paranasal sinuses surgery.Therefore, the aim of this chapter was to examine the paranasal sinus anatomic variations with cone beam computed tomography (CBCT).
