Anatomical variations in the maxillary sinus pneumatisation are limited unlike the ethmoids. We present rare variations of the maxillary sinus along its floor other than septations and includes wide pneumatisation of alveolar and palatal recess with cell formation. An intra-maxillary cell that opens into the maxillary infundibulum well within the sinus is described here and our senior author has coined the new term-alveolar recess cell. Its involvement in the sinus pathologies and additional surgical approaches for the disease clearance is discussed here.

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.

To observe the position and morphology of tubular cell in lateral facial recess by CT scanning and surgical finding, and its clinical significance. Thirty patients(32 ears) with cholesteatoma and/or adhesive otitis media requiring radical mastoidectomy and tympanoplasty were included in this study. To observe the morphology of the tubular cell in the lateral facial recess cavity through temporal bone HRCT and surgery, and to analyze its relationship with the facial nerve.

Those using the mouse for the purposes of electrophysiological research presume that the morphology of the conduction axis is comparable with the human arrangement. As yet, however, to the best of our knowledge, no direct comparison has been made between the species. By comparing our extensive histological findings in the human heart with comparable serially-sectioned datasets prepared from adult murine hearts, we aimed to provide this information.

In this review, we summarise the ongoing debate surrounding the anatomy of the atrioventricular conduction axis and its relevance to pacing. We highlight previous disagreements and emphasise the importance of understanding the anatomical location of the axis. We give credit and support to the initial descriptions by His and Tawara, in particular their attention to the relationship of the atrioventricular conduction axis with the membranous septum.

Background: Crocodiles are semi-aquatic animals well adapted to hear both on land and under water. Currently, there is limited information on how their amphibious hearing is accomplished. Here, we describe, for the first time, the ear anatomy in the living crocodile using photon-counting detector computed tomography (PCD-CT) and 3D rendering.
