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. KEYWORDS: frontal rhinosinusitis, anatomy variation, nasofrontal complex, frontal sinus drainage

Sinus Drainage

Background The indication for frontal sinus drainage is uncertain when managing pediatric acute sinusitis with intracranial complications. Objective The primary objective was to determine if addressing the frontal sinus reduced need for subsequent surgical procedures in children presenting with acute sinusitis complicated by intracranial abscess. Methods A case series with chart review was performed at a tertiary children’s hospital between 2007 and 2019. Children under 18 years of age requiring surgery for complicated acute sinusitis that included the frontal sinus with noncontiguous intracranial abscess were included. Outcomes were compared among children for whom the frontal sinus was drained endoscopically, opened intracranially, or left undrained. Results Thirty-five children with a mean age of 11.1 years (95% CI: 9.9-12.3) met inclusion. Most presented with epidural abscess (37%). Hospitalizations lasted 12.9 days (95% CI: 10.2-15.5), 46% required a second surgery, 11% required three or more surgeries, and 31% were readmitted within 60 days. Initial surgery for 29% included endoscopic frontal sinusotomy, 34% had a frontal sinus cranialization and 37% did not have any initial drainage of the frontal sinus. Groups were similar with respect to demographics, severity of infection, need for repeat surgery, length of stay, and readmissions (p > .05). Further, persistence of cranial neuropathies, seizures, or major neurological sequelae after discharge were no different among groups (p > .05). Conclusion Drainage of the frontal sinus, when technically feasible, was not associated with reduced surgical procedures or increased complications and there is unclear benefit on measured clinical outcomes.

Sinus Drainage

Background To date, there are numerous studies documenting the prevalence of frontal recess cells, but only 1 study using the newly developed International Frontal Sinus Anatomical Classification (IFAC) system. The identification of the frontal cells and their influence on the frontal drainage pathway plays an important role in endoscopic frontal sinus surgery. Objective The aim of this study is to document the radiological prevalence of various types of frontal cells, as classified by IFAC and the most common frontal sinus drainage pathways based on its anatomic relationships with these cells. Methods Using a novel preoperative virtual planning software (Scopis Building Blocks), consecutive computerized tomography scans of the sinuses of patients were analyzed for the prevalence of frontal cells, as classified by the by IFAC, and the frontal sinus drainage pathways at the Ear Nose Throat Hospital of Ho Chi Minh City, Vietnam. Results In this study, 208 computed tomography scans of consecutively selected frontal sinuses of 114 patients were included for analysis. The agger nasi cell was present in 95.7% of reviewed scans. The frontal cells prevalence was as follows: supra agger cell (SAC): 16.3%, supra agger frontal cell (SAFC): 13%, supra bulla cell (SBC): 46.2%, supra bulla frontal cell (SBFC): 4.3%, supra orbital ethmoid cell: 17.3%, and frontal septal cell: 10.6%. The most common frontal sinus pathway type in relation to frontal cells was medial to SAC (70.6%), medial to SAFC (81.5%), anterior to SBC (88.5%), and anterior to SBFC (100%). In cases that had 2 frontal cells group, the drainage pathway was medial to SAC/SAFC and anterior to SBC/SBFC in most cases. Conclusion This study documents the prevalence of frontal cells (classified by IFAC) using a novel preoperative virtual planning software in the Vietnamese population. It demonstrates predominantly medial anteromedial frontal drainage pathways as related to these frontal cells.
