Haller cells | Radiology Reference Article | Radiopaedia.org
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. They are present in ~20% (range 2-45%) of patients, depending on their exact definition 1-3.
Infraorbital ethmoid (Haller's) cells: a panoramic ...
Haller's cells or infraorbital ethmoid cells refer to the ethmoidal pneumatization of the superior aspect of the maxillary sinus and floor of the orbit. The clinical importance of these entities initiated this study with an aim to determine the ...
Role of Haller's cell in headache and sinus disease: a case ...
Haller's cells may cause recurrent or chronic sinusitis and persistent sinugenic headache, without significant findings on physical examination including nasal endoscopy. The presence of Haller's cells on coronal CT in a patient with corresponding symptoms deserves consideration as the potential cause of the symptoms.
Prevalence of Haller's Cells: A Panoramic Study - PMC
Haller's cells or infraorbital ethmoid cells refer to the ethmoidal pneumatization of the superior aspect of the maxillary sinus, and floor of the orbit can be seen on panoramic radiographs. They appear as well-defined, round-, oval-, or teardrop-shaped radiolucencies with smooth corticated or noncorticated borders. Aims and Objective:
The anatomic relevance of the Haller cell in sinusitis
Haller cells, an extension of ethmoid pneumatization along the maxillary antrum roof, have also been suggested as a causative factor in sinusitis because of their ability to cause narrowing of the infundibulum.
Cone beam CT analysis of Haller cells: prevalence and ...
2013年9月3日 · We suggest that the role of Haller cells in sinus disease should be evaluated on an individual basis depending on the size of Haller cells and clinical evidence of sinus inflammation. Our study showed a significant association between …
Cone Beam CT Analysis of Haller Cells: Prevalence and ...
2023年1月31日 · The overall prevalence of Haller cells was 56.7%, of which 44 (64.7%) were unilateral and 24 were bilateral (35.3%). The majority of the cells (70.7%) were seen in medium (2–4 mm) sized. There was a significant association between Haller cells and orbital floor dehiscence ( p ≤ 0.001).
A Study on the Assessment of Haller Cells in Panoramic ...
The present study assessed the prevalence of Haller cells as 22.8%, and this was done in a cost-effective way using panoramic radiographs. This would aid in determining Haller cells as an etiological factor for the chronic orofacial pain with undiagnosed etiology.
Anatomy and Variations of Onodi Cells and Haller Cells: A ...
2021年8月28日 · The Onodi cell is defined as the posterior-most ethmoid cell. Haller cells are defined as infraorbital ethmoid cells. HRCT scanning provides excellent bone detail and accurate soft tissue mapping. The aim of this study is to know the prevalence of Haller cells and Onodi cells and to find variations in them on HRCT.

Haller’s cells are air cells located below the ethmoid bulla along the roof of the maxillary sinus. They have been often implicated in several sinonasal diseases.
