Haller cell

Hal·ler cell

a variant of ethmoidal air cell developing into the floor of the orbit adjacent to the natural ostium of the maxillary sinus. A diseased Haller cell is capable of obstructing that ostium and producing a maxillary sinusitis.

Some patients demonstrate abnormal Haller cell communicating with maxillary sinus as shown in Fig.
Twelve areas were specifically looked at for anatomical variations (Table 1) including; Type of skull base, Anterior ethmoid artery, Agger nasi cells, Haller cells, asymmetry in anterior ethmoidal and onodi cells.
The scans were reviewed for the presence of deviated nasal septum, paradoxical middle turbinate, Haller cell, Onodi cell, and pneumatisation of the middle turbinate and uncinate process.
Each scan was reviewed for the presence of haller cell, onodi cell, paradoxical middle turbinate, deviated nasal septum (DNS), pneumatisation in the nasal septum, superior and middle turbinate, and uncinate process.
The Haller cell was resected and was found to contain a mucocele full of thick, yellow mucus (figure, D).
Albert Van Haller Cell inferior to ethmoid bulla adhering to the roof of the maxillary sinus, in continuity with the proximal infundibulum which formed part of the lateral wall of the infundibulum: Zinreich and Kennedy.
Bolger also suggested that a narrow window setting often fails to delineate Haller cell (22).
Haller cells are located below the bulla ethmoidalis and extend beneath the floor of the orbit (Figs 4 and 5).
Computed tomography (CT) of the sinuses demonstrated prominent Haller cells impinging on the ethmoid infundibulum and the maxillary sinus outflow tracts (figure, A).
The parameters used for correlation were- Deviated Nasal Septum, Inferior Turbinate Hypertrophy, Middle Turbinate abnormalities, Concha Bullosa, Agger Nasi cells, Haller cells, Frontal recess, Infundibulum, Hiatus semilunaris, Uncinate process attachment, Intrasinus mucosal disease of Maxillary, Ethmoids, Frontal and Sphenoid detailed history, clinical examination and routine investigations were done for the patients.
The anatomic variations studied include concha bullosa, paradoxical middle turbinate, retroverted uncinate process, overpneumatized ethmoid bulla, haller cells, agger nasi cells and septal deviation.
