Summary
Anatomical variations like deviated nasal septum may contribute to acute rhinosinusitis. However, teeth in the maxillary sinus are common and not always linked to sinusitis development.
Area of Science:
- Otolaryngology
- Medical Imaging
- Pathophysiology
Background:
- Sinonasal anatomical variants are implicated in acute rhinosinusitis etiology.
- Teeth intrusion into the maxillary sinus is a recognized condition.
Purpose of the Study:
- To investigate the association between sinonasal anatomical variants and refractory acute rhinosinusitis.
- To evaluate the role of tooth intrusion in maxillary sinusitis.
Main Methods:
- Prospective enrollment of patients with acute rhinosinusitis unresponsive to maximal medical treatment.
- Assessment of sinonasal anatomy, including nasal septum deviation and maxillary sinus contents.
Main Results:
- Nasal septum deviation towards the infected sinus may correlate with the pathogenesis of refractory acute rhinosinusitis.
- Intrusion of teeth into the maxillary sinus is a frequent finding.
- Tooth intrusion alone is not necessarily associated with sinusitis formation.
Conclusions:
- Nasal septum deviation is a potential factor in refractory acute rhinosinusitis.
- Maxillary sinus tooth intrusion is common and often asymptomatic, not requiring intervention for sinusitis.

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
