What is bilateral Haller air cells?

Haller cells, also known as infraorbital ethmoidal air cells, are ethmoid air cells located lateral to the maxillo-ethmoidal suture along the inferomedial orbital floor. It may narrow the ipsilateral ostiomeatal complex (OMC) if large, thereby predisposing the ipsilateral maxillary antrum to obstruction.

What is a Haller cell?

Haller’s cells are defined as air cells situated beneath the ethmoid bulla along the roof of the maxillary sinus and the most inferior portion of the lamina papyracea, including air cells located within the ethmoid infundibulum. Haller’s cells are thought to arise in individuals with pneumatization of the lateral crus.

How do you treat Haller cells?

The presence of Haller’s cells on coronal CT in a patient with corresponding symptoms deserves consideration as the potential cause of the symptoms. When medical therapy is ineffective, such cases respond well to surgical therapy through the functional endoscopic approach.

Are Haller cells Bad?

Conclusion: Haller cells can interfere with the normal drainage of the maxillary sinus and result in sinusitis. In contrast, diameter of the sinus ostium and deviation of the uncinate process do not influence the inflammatory status of the maxillary sinus significantly.

Where are the Haller cells located in the orbit?

Highlights: 1 Definition: Ethmoidal air cells that extend along the medial floor of the orbit. 2 Haller cells lay posterosuperior to the natural maxillary os. 3 They may act to narrow the ethmoidal infundibulum. 4 Named after Albrecht von Haller, a Swiss anatomist. More

Where are Haller cells located in the inferomedial?

Haller cells , also known as infraorbital ethmoidal air cells, are ethmoid air cells located lateral to the maxillo-ethmoidal suture along the inferomedial orbital floor. It may narrow the ipsilateral ostiomeatal complex (OMC) if large, thereby predisposing the ipsilateral maxillary antrum to obstruction. Haller cells lead to inattentive entry

How often are Haller cells found in patients?

They are present in ~20% (range 2-45%) of patients, depending on their exact definition 1-3. In most instances they are asymptomatic and (although some controversy exists 4,5) they are generally not thought to be associated with increased rates of sinusitis 3. They may become clinically significant in a number of situations:

Is the presence of Haller cells related to sinusitis?

The incidence of Haller cells has been reported to vary from 2–45%, and although some reports have found a statistically significant relationship between maxillary sinusitis and medium or large Haller cells (1), it is generally believed that the presence of a Haller cell is not related to sinusitis (2, 3).
