TL;DR: The results support the use of a clinical technique of sagittally splitting the mandibular ramus, which maximizes attachment of the pterygomasseteric sling and mucoperiosteum.
Abstract: Ten adult rhesus monkeys were used as experimental models to investigate revascularization and bone healing associated with sagittal splitting of the mandibular rami by two different techniques. Microangiographic and histologic studies showed intraosseous ischemia in the margins of the osteotomized segments and areas where the pterygomasseteric sling had been detached. When the mucoperiosteum and pterygomasseteric sling were minimally detached from the proximal segment, intraosseous ischemia and necrosis were significantly reduced. The results support the use of a clinical technique of sagittally splitting the mandibular ramus, which maximizes attachment of the pterygomasseteric sling and mucoperiosteum.
TL;DR: A systematic study of the associated histopathologic changes in the middle ear, bulla and eustachian tube is proposed to provide information as to the manner in which effusions develop and thereby properly orient treatment.
Abstract: After it was demonstrated that effusions could be produced regularly in the experimental animal/ it became possible to make a systematic study of the associated histopathologic changes in the middle ear, bulla and eustachian tube. It is hoped that the knowledge acquired from such a study would provide information as to the manner in which effusions develop and thereby properly orient treatment.
TL;DR: It appears that clinically significant aseptic necrosis following mandibular osteotomies is a more infrequent occurrence than that following maxillary surgery because only two cases were reported in a questionnaire dealing with major vascular complications following orthognathic surgery.
TL;DR: It is postulated that mast cells located in the lamina propria of the tympanic mucoperiosteum are triggered to degranulate and release histamine by anaphylatoxin derived from activation of the complement system.
Abstract: The presence of histamine in 131 middle ear effusions was determined by the fluorometric assay technique. This potent mediator of inflammation was found in significant amounts in most of the samples, suggesting that it may play an important role in the pathogenesis of otitis media with effusion. It is postulated that mast cells located in the lamina propria of the tympanic mucoperiosteum are triggered to degranulate and release histamine by anaphylatoxin derived from activation of the complement system.
TL;DR: How to resurface the nasopharyngeal defects in endoscopic endonasal approaches to avoid persistent postoperative headache has not been reported.
