ABSTRACT Haller cell was first described by 18th century Swiss anatomist Albrecht von Haller. Haller cells make up the posterior and superior wall of the ethmoid infundibulum. They can cause obstruction of ethmoidal infundibulum after enlargement. Isolated infection of the Haller cell is usually very rare and should be suspected in patients with visual complaints or facial pain. Diagnosis can be made on radiology. Here, we report a patient with complaints of left-sided eye pain for the last 4 months which was finally diagnosed as Haller cell mucocele and successfully managed via endoscopic mar

Abstract:

In current theories of sinusitis, obstruction at the ostiomeatal complex leads to localized inflammation and infection. 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. Coronal CT scans were reviewed in 154 patients to evaluate the role of Haller cells in sinusitis. Haller cells were present in 34% of patients. The cells were graded as small, medium, or large, and correlated with radiologic evidence of sinusitis (e.g., mucosal thicken

Introduction Agger nasi and haller cells are few of the common anatomical variants of Paranasal Sinuses (PNS) . They can cause obstruction of osteomeatal complex and frontal recess and can cause refractive sinusitis. Also these variants can lead to complications during procedures like Functional Endoscopic Sinus Surgery (FESS). Hence, complete knowledge about these variants and imaging features help in early diagnosis and also helps in avoiding complications during surgery.

Abstract:

Haller’s cells are infraorbital ethmoidal cells located along the inferior wall of the orbit. They were first described by Albrecht von Haller in 1743 and were subsequently named after him. The reported prevalence of these cells varies significantly from 2.7% to 45.1%. They are a variant of the normal anatomical structure of the paranasal sinuses. These cells are often incidental findings on computed tomography (CT) of the nasal cavity and paranasal sinuses. Haller’s cells may predispose patients to maxillary sinusitis and may complicate maxillary sinus surgery. In addition, isolated inflammat

In a long-term transformation, that begins in Antiquity but takes a crucial turn in the Renaissance anatomies, the “fibre” becomes from around 1750 the operative building block and at the same time the first unifying principle of function-structure-complexes of organic bodies. It occupies the role that the cell takes up in the cell œconomies of the second third of the nineteenth century. In this paper, I will first discuss some key notions, technical analogies, and images that are related to “fibre”-concepts from Andreas Vesalius to Albrecht von Haller and then focus on Charles Bonnet’s and De

Abstract:

L2 cells, a cloned pneumocyte-derived cell line, express voltage-dependent L-type Ca2+ channels, causing transient depolarizing spikes of the membrane potential (Vm) [P. Dietl, T. Haller, B. Wirleitner, H. Volkl, F. Friedrich, and J. Striessing. Am. J. Physiol. 269 (Lung Cell. Mol. Physiol. 13): L873-L883, 1995]. In this study, we examined the effect of nitric oxide (NO)- and guanosine 3',5'-cyclic monophosphate (cGMP)-dependent cell signaling on the activity of L-type Ca2+ channels. Using conventional microelectrodes, spontaneous depolarizations (SD) of Vm by activation of these channels are

Abstract:

Background/Aim: Anatomical variations of paranasal sinuses are common and play an role in disrupting the drainage of the sinuses, which often causes chronic sinusitis. In this article, anatomical variations of the paranasal sinuses and its relationship with mucosal changes were evaluated retrospectively by cone beam computed tomography (CBCT) which is also known as dental volumetric tomography. Material and Methods: CBCT data of 500 patients who applied to Cukurova University Faculties of Dentistry for any reason were retrospectively evaluated by maxillofacial radiologist.

Abstract:

Pulmonary surfactant is secreted via exocytosis of lamellar bodies (LBs) by alveolar type II cells. Here we analyzed the dependence of LB exocytosis on intracellular Ca2+concentration ([Ca2+]i). In fura 2-loaded cells, [Ca2+]iwas selectively elevated by flash photolysis of a cell-permeant caged Ca2+ compound ( o-nitrophenyl EGTA-AM) or by gradually enhancing cellular Ca2+influx. Simultaneously, surfactant secretion by single cells was analyzed with the fluorescent dye FM 1-43, enabling detection of exocytotic events with a high temporal resolution (T. Haller, J. Ortmayr, F.

Aim: Computed tomography (CT) provides an accurate assessment of sinonasal anatomy and osseocartilaginous pathologies in patients complaining of sinonasal symptoms. Although it is not a routine practice, CT is frequently used in preoperative screening of patients planned for septoplasty and septorhinoplasty. In this study, anatomical variations and ethmoid lateral lamella depths in preoperative CT images of septoplasty and septorhinoplasty operations performed in our clinic were analyzed retrospectively and discussed with current literature. Material and Method: Septorhinoplasty and sept

Background and Objectives: Sinonasal fungal balls (FBs) most commonly occur in the maxillary sinus, followed by the sphenoid sinus (SS). Relatively little is known about the predisposing factors and pathogenesis of unilateral sphenoid sinus fungal balls (SSFBs) compared to maxillary sinus FBs. We investigated whether anatomical variations have clinical implications for the location of unilateral SSFBs.Methods: This study included 33 patients who underwent endoscopic sinus surgery for unilateral SSFBs between 2010 and 2021.

Evaluation of sphenoid sinus pneumatization, lamina papyracea, onodi cell, cribriform plate, types of optic canal and supraorbital pneumatisation are useful for evaluation of the surgical anatomy of paranasal sinuses for the radiologist which guides the surgeon to take a correct approach for surgery without major complications of crucial structures.
