Frequency of the odontogenic maxillary sinusitis extended to the anterior ethmoid sinus and response to surgical treatment

Abstract

Objectives: Odontogenic sinusitis usually affects the maxillary sinus but may extend to the anterior ethmoid sinuses. The purpose of this study is to determine the percentage of odontogenic maxillary sinusitis extended to the anterior ethmoid sinuses and determine also the surgical resolution differences between odontogenic maxillary sinusitis and odontogenic maxillary associated to anterior ethmoidal sinusitis. Study Design: This is a retrospective cohort study performed on 55 patients diagnosed of odontogenic sinusitis and treated surgically by functional endoscopic sinus surgery. Results: This study showed that 52.7% of odontogenic maxillary sinusitis spreads to anterior ethmoid, causing added anterior ethmoid sinusitis. We found that 92.3% of the odontogenic maxillary sinusitis (who underwent middle meatal antrostomy) and 96.5% of the odontogenic maxillary sinusitis extended to the anterior ethmoid (treated with middle meatal antrostomy and anterior ethmoidectomy) were cured. Conclusions: Ethmoid involvement is frequent in maxillary odontogenic sinusitis. The ethmoid involvement does not worsen the results of “functional endoscopic sinus surgery” applied to the odontogenic sinusitis. Key words:Odontogenic maxillary sinusitis, ethmoiditis, functional endoscopic sinus surgery.

Aktueller Stand der endonasalen Nasennebenhöhlenchirurgie

“…Parallel erfolgt eine zahnärztliche Therapie. Bei Persistenz von Beschwerden (meist purulente Sekretion, putrider Geruch, Schmerzen) und pathologischem Befund (purulente Sekretion, Obstruktion der ostiomeatalen Einheit) ist eine Nebenhöhlenchirurgie erforderlich [695,696]. Im Falle einer Fremdkörperimpaktion besteht die Indikation zur Entfernung immer.…”

Is dental evaluation considered in unilateral maxillary sinusitis? A retrospective case series

“…The inclusion and exclusion criteria are shown in Table 1. To summarize, adult patients (18 years of age) with a unilateral maxillary sinus opacification on CT that could extend to the anterior ethmoidal sinuses and the frontal sinus on the same side and sino-nasal symptoms were included [2,19].…”

Distinguishing the dominant species of pathogen in ethmoidal sinusitis by sequencing DNA dataset analysis

“…Ethmoidal sinusitis occurs in the unilateral sinus, and can be identified via the thickening of the ethmoid sinus mucosa, bone destruction at the top of the sieve, polyps obstruction in the meatus nasi medius, olfactory cleft and purulent secretion in the middle meatus in the meatus nasi medius (17,18). Ethmoidal sinusitis is usually classified as acute ethmoidal sinusitis and chronic ethmoidal sinusitis (3,7).…”

“…Chronic sinusitis is often associated with chronic maxillary sinusitis (14). Pathogenic microorganisms penetrate the mucosal barrier to invade blood vessels or bone, which can cause vasculitis, vascular embolization, bone destruction and tissue necrosis (17). Severe infections of the ethmoid sinus often lead to fungal meningitis, encephalitis and brain necrosis, which, altogether, have a mortality rate between 50 and 100% (20).…”
