This overview assesses some distinguishing features of the cetacean (whale, dolphin, porpoise) air sac system that may relate to the anatomy and function of the paranasal sinuses in terrestrial mammals. The cetacean respiratory tract has been modified through evolution to accommodate living in water. Lack of paranasal sinuses in modern cetaceans may be a diving adaptation. Bone-enclosed air cha...

The lymphatic sinuses in human lymph nodes (LNs) are crucial to LN function yet their structure remains poorly defined. Much of our current knowledge of lymphatic sinuses derives from rodent models, however human LNs differ substantially in their sinus structure, most notably due to the presence of trabeculae and trabecular lymphatic sinuses that rodent LNs lack. Lymphatic sinuses are bounded a...

The author had reported two princiles in construction and reaction of the lumen organ (middle ear, paranasal sinuses, lung and salivary grand) in the foregoing reports. In this paper an atempted was made to find these principles in the paranasal sinuses. The first principle is as follows; The lumen organ consists of two forms, namely cell form and antrum form. And the organ in which the cell fo...

The aims of this study are to determine the intra-observer and inter-observer agreement between the two radiologists when reporting the Waters view and 3 views series of the paranasal sinus radiographs. To also determine whether a single Waters view is adequate for diagnostic purpose of sinusitis. 90 sets of paranasal sinuses radiographs were reported by two radiologists independently. The resu...

The origin of the polymorphonuclear leucocytes found in the intermediary and subcapsular sinuses of the popliteal lymph node during acute bacterial lymphadenitis, and the effect of this leucocyte infiltration on the passage of bacteria through the lymph node have been investigated. It has been demonstrated that: 1. The polymorphonuclear leucocytes in the nodal sinuses originate both from blood ...

We reported simple partial root remodeling using a graft trimmed twin "U" shape for extensive dissection into the right/non-coronary sinuses with acute type A aortic dissection with cardiac tamponade, acute myocardial infarction on the right coronary artery and aortic regurgitation. After total arch replacement with frozen elephant trunk technique for distal dissection, partial root remodeling ...

BACKGROUND AND PURPOSE Three-dimensional (3D) constructive interference in steady state (CISS) MR imaging is useful for demonstrating cranial nerves (CNs) in the cistern. The purpose of this study was to evaluate normal CNs III, IV, V1, V2, and VI in the cavernous sinuses by using contrast-enhanced, three-dimensional (3D), Fourier transformation CISS MR imaging. METHODS In 76 normal cavernous...

Nasopharyngeal carcinoma (NPC) may spread to the paranasal sinuses. This retrospective study describes the features of paranasal sinus involvement in NPC on computed tomography (CT) and magnetic resonance imaging (MRI). One hundred and fourteen patients with histologically proven NPC underwent staging with both CT and MRI. Maxillary sinus infiltration was demonstrated on MRI in 10 patients; sph...

Introduction: The close relationship between diseases of the paranasal sinuses system and the orbit is based on their anatomical relationship. About 60% to 80% of the osseous eye socket is made up by sinus walls. Objective: To describe evaluation of orbital complications in patient with paranasal sinuses diseases at Dr. M. Djamil Hospital Padang for 2005-2014. Method: Descriptive study we obtai...
