Purpose:
The aim of this study was to review clinical and radiological presentation, surgery, and results of treatment in patients with chronic odontogenic maxillary sinusitis (OMS) treated with a single surgical procedure, including endoscopic sinus surgery (ESS) and oral surgical approaches to treat the odontogenic source of infection.
Materials And Methods:
A retrospective case series analysis of 98 patients was performed. All the patients received ESS. 88 patients required oral surgical approaches.
Results:
Nasal symptoms were present in 58 patients (59.2%). Nasal endoscopy was positive in 65 patients (66.3%). A positive nasal endoscopy was significantly associated with nasal symptoms (p < 0.05). 60 patients (61.2%) had OMS of iatrogenic origin. Total opacification of the maxillary sinus was the most common radiological presentation (74.5%) and was significantly associated with nasal symptoms (p < 0.05). 91 patients (92.9%) had complete clinical and radiological resolution of the OMS.
Conclusions:
Iatrogenic origin, sinonasal symptoms and positive clinical endoscopy are common in patients with OMS. Nasal symptoms were significantly associated with total maxillary sinus opacification and positive endoscopic clinical examination. Combining treatment of the odontogenic source of infection via an oral surgical approach and of the sinus inflammation by ESS appears to be sufficient for successfully treating patients with OMS.

Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...

Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying.
