“…that most of the frontal sinus drained to the middle meatus (medial to the superior attachment of the uncinate process, 66%) rather than draining to the ethmoid infundibulum (lateral to the superior attachment of the uncinate process, 34%). Although the junction of the superior portion of the uncinate process and the superior portion of the ethmoid bulla (termed suprainfundibular plates) was also used to locate the frontal sinus outflow tract, the distribution of the 2 types of frontal sinus drainage was still similar (59 vs. 40%) [9] . Our results are consistent with the above studies; we found that in Chinese subjects most of the uncinate processes had 1 superior attachment (65.3%) and more than half of the frontal sinus drainage pathways were medial to the superior attachment of the uncinate process (53.1%, fig.…”

“…Two anatomical factors are important for the understanding of the anatomy of the frontal recess, namely the uncinate process [9][10][11][12] and the agger nasi cell [7,8] . While the superior attachment of the uncinate process was thought to play a key role in determining the frontal sinus drainage pathway [9][10][11][12] , the classification and variations of the frontal recess cell, especially the agger nasi cell and its related cells, have been regarded as landmarks for unlocking our understanding of the frontal recess [7,8] .…”

The purposes of this study were to determine the prevalence of frontal-ethmoidal cells and to evaluate variation in the superior attachment of the uncinate process in Chinese subjects. 202 normal Chinese subjects (404 sides) underwent spiral computed tomography and multiplanar reconstruction images were evaluated. Agger nasi cells showed a prevalence of 94.1%. Of all the frontal cells identified in 159 sides (39.6%) of frontal recesses, the prevalence of type I, type II and type III cells was 24.4, 7.0 and 8.2%, respectively. Suprabullar, frontal bullar and interfrontal septal cells were identified in 148 sides (36.6%), 36 sides (9.0%) and 25 subjects (12.4%), respectively. 244 uncinate processes (60.4%) had 1 superior attachment and the remainder (39.6%) had 2 superior attachments. The prevalence of terminal recesses was 89.1%. Our results characterized normal frontal recess pneumatization patterns in Chinese subjects. That, together with variation in the superior attachment of the uncinate process, emphasized the role of agger nasi cells and the uncinate process in endoscopic frontal sinus surgery.

“…There have been many reports describing the anatomy of the lateral nasal wall (Sato et al, 2000;Yoon et al, 2000;Kim et al, 2001a;Kim et al, 2001b). However, there are few reports describing the middle turbinate, which is believed to be a very important landmark when performing ESS.…”

Clinicians have encountered many variations of the middle turbinate. Previous descriptions of the middle turbinate were only focused on its size and shape and lacked surgical implications associated with endoscopic sinus surgery. Therefore, the aim of this study was to examine the surgical anatomy of the middle turbinate in hemisected cadaveric heads. The middle turbinates from 101 hemisections of adult Korean cadaveric heads were measured using digital calipers and a protractor. The middle turbinates were then classified according to their shape. The mean distance between the anterior attachment of the middle turbinate and the anterior attachment of the superior turbinate was 18.5 mm. The posterior end of the middle turbinate extended more posteriorly than that of the inferior turbinate in 40% of the cases, while in 26.3% of the cases, the posterior end of the inferior turbinate extended more posteriorly than that of the middle turbinate. The middle turbinate was classified into three types according to the shape of its anterior border. In type 1, the anterior border of the middle turbinate ran directly posteroinferiorly from its attachment to the conchal plate, and was observed in 45.3% of the cases. In type 2, the anterior border of the middle turbinate initially coursed inferiorly from the conchal plate and then turned in a posteroinferior direction. This type was observed in 44.2% of the cases. Type 3 involved 10.5% of the cases where the anterior border bulged anteriorly before it coursed posteroinferiorly. The information provided in this report should assist surgeons when performing partial middle turbinectomies.

“…In frontal sinus drainage from the lateral side, UP acts as a anatomic barrier, valve between the meatus medius and frontal recess, which can result in system flow frontal sinus opens into the ethmoid infundibulum. (1,8,11) This physiological process may play a role in the pathogenesis of frontal sinusitis in individuals who have a flow system to the medial of frontal sinus (group 1) should lack a anatomical barrier to prevent rising irritant or allergen and rhinogenic infection.…”

BACKGROUND: This research was conducted to find out the relation of anatomy variation of nasofrontal complex on the frontal sinus drainage system with frontal rhinosinusitis incident. METHODS: This research was using cross-sectional design involving 75 patients with chronic rhinosinusitis. Coronal paranasal sinus CT scan with sagittal plane reformat was carried out to examine. The CT scan figures were analyzed from every side and there were 150 samples found as the result. Data was analyzed using chi square test. RESULTS: The research indicates that there is no significant relation between frontal cell types, agger nasi cell, chonca media bullosa with incident of frontal rhinosinusitis (p>0.05). Prevalence of superior attachment of uncinate process (UP), type 1 (UP superior attachment on lamina papiracea) was found on 43 sides (28.6%), type 6 (UP superior attachment to medial turbinate) was found in 29 sides (19.3%). Prevalence of frontal rhinosinusitis was found in 42 (28%) from 150 sides. Group 1 drainage (medial side drainage; drainage to meatus medius [type 1-3]) was found in 32 sides (76.2%) and group 2 drainage (lateral side drainage; drainage to infundibulum ethmoid [type 4-6]) was found in 10 sides (23.8%). CONCLUSION: There is significant relation between frontal rhinosinusitis incident with variation of frontal sinus drainage (p<0.05) and drainage on group 1 has significant existence statistically on frontal rhinosinusitis incident.

Surgical Anatomy of the Nasofrontal Duct: Anatomical and Computed Tomographic Analysis

Abstract: To widen the nasofrontal communication, removing the upper portion of the ground lamella of the ethmoid bulla, which is the posterior boundary of the nasofrontal duct, with cutting forceps seems to be a safe and easy method.
