“…In the literature distribution of agger nasi cells are between 78 and 98.5 % of the patients. According to Landsberg and Friedman [13] agger nasi cells were found in 78 % of scans. Bolger et al [14] has found the prevalence in 98.5 % of their cases.…”

“…In our study the superior attachment of the uncinate process to lamina papyraceae was 82 %, to middle turbinate was 4 % and to the skull base was 14 %. According to Landsberg and Friedman [13], the uncinate process main superior attachment onto the surrounding structures was found to have the following distribution; 52 % to the lamina papyraceae, 18.5 % to posteromedial wall of agger nasi cell, 17.5 % to the lamina paparaceae and the junction of the middle turbinate with the cribriform plate, 3.6 % to ethmoid roof and 1.4 % to the middle turbinate. In a study in Taiwanese population, Liu et al [17] had found that single insertion of the uncinate process onto the lamina papyraceae was the most common type (70.4 %) as in our study.…”

A study designed to describe the anatomical features of the frontal recess area in patients suffering from chronic frontal sinusitis. A prospective study done in adult patients admitted in our hospital between July 2009 to June 2011. Tertiary level, private ENT care centre. 50 adult patients of chronic frontal sinusitis who did not have history of previous sinus surgery. The frontal recess anatomy was studied by 2 mm slice CT scans pre-operatively. CT findings were confirmed intra operatively by meticulous dissection in frontal recess area endoscopically with aid of image guided system. A chart prepared for each patient of different anatomical variations present in frontal recess on each nasal side and analyzed. Agger nasi cell was found in 94 % of cases. The superior attachment of the uncinate was to the lamina papyraceae in 82 % of cases. Type 1 frontal recess cells were found in 44 %, type 2 in 8 %, type 3 in 48 % and type 4 in 2 % of the cases. Over all 74 % of cases had frontal recess cells.

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.

“…The frontal sinus patency can be achieved by merely exposing the natural sinus ostium with only a rare need to enlarge it [14]. This procedure usually has the superior attachment of uncinate process and suprainfundibular plates as the most important landmarks [4,15,16]. However, the anatomical structures and landmarks can be compromised by severe polypoid lesions in anterior ethmoid sinus or by previous surgery or by postoperative scarring.…”

To modify the endoscopic frontal sinus surgery and improve the therapeutic effect of recurrent chronic frontal sinusitis (RCFS). Eighty-five patients with RCFS were divided into two groups. Endoscopic frontal sinus surgery through an approach of Frontomaxillary ProcessAgger Nasi, a modified Draf IIb procedure, was carried out in 51 patients (Group A), and conservative medication was applied in 34 patients as control (Group B). The therapeutic effect was prospectively evaluated with statistically validated measures of sinusitis-specific quality of life, sinonasal outcome test-20 questionnaire . Compared with pre-treatment, the average total score of SNOT-20 in RCFS patients was significantly decreased at the time of 6, 12 months after modified endoscopic frontal sinus surgery and medical treatments (p \ 0.05). However, the total score of SNOT20 was significantly lower in group A than group B at the same period of the follow-up after treatments (p \ 0.05). The overall efficacy evaluated by patients' self showed that the rate of ''much improved'' and ''improved'' was respectively 68.6 and 17.6 % in group A, and significantly better than group B (p \ 0.001). Furthermore, the frontal sinus patency rate in group A was 85 %, and significantly higher than group B (p \ 0.001). Endoscopic frontal sinus surgery through an approach of Frontomaxillary Process-Agger Nasi, a modified Draf IIb procedure, is an effective procedure to treat the RCFS.
