Transparent Display of the Internal Pulmonary Interlobar Surfaces

Description

Transparent rendering isolates the facies interlobares of the lungs, with the fissural planes separating the lobar units and outlining their boundaries in profile. The oblique fissure is read as a long, inferoanteriorly directed cleft between superior and inferior lobes, while the horizontal fissure on the right lung lies more superiorly and runs anteroposteriorly to divide the upper and middle lobes. Visceral pleura coats each lobar surface, so adjacent interlobar faces sit in apposition with only a potential space between them. Clean fissures. Clear margins. Fissural anatomy is where lobar localization becomes practical, and a transparent treatment makes that spatial logic easier to teach and to plan around. Incomplete fissures, accessory fissures, and pleural adhesions can limit lobar mobility and complicate thoracoscopic lobectomy or segmentectomy by blurring the intended dissection plane and increasing the risk of prolonged postoperative air leak. Radiologists also lean on these planes when assigning a pneumonia, atelectasis, or a peripheral nodule to a specific lobe on chest CT, since disease respects lobar boundaries more often than it respects external surface landmarks. Use this artwork in gross anatomy and respiratory system courses to anchor the terminology of fissural (interlobar) surfaces, and in surgical education materials discussing VATS port placement and fissure-based versus fissureless approaches to lobectomy. It also suits radiology atlases and pulmonary teaching files where correlating CT fissures with lobar distribution matters. Anatomical accuracy verified by SciePro's Medical Advisory Board.
