        The use of precontoured plates for midshaft clavicle fractures is not always the best course of treatment

        Manmohan Patel,Mohtashim Ahmad,Natwar Agrawal,Sumit Tulshidas Patil,John Ashutosh Santoshi,Bertha Rathinam,Kusum Rajendra Gandhi 대한해부학회 2023 Anatomy & Cell Biology Vol.56 No.4

        Plate fixation has become the preferred approach for treating displaced midshaft clavicle fractures. However,plate fixation of the clavicle presents several unique challenges, including its complex bony architecture and its immediatesubcutaneous location. In many cases, we have observed that precontoured implants do not conform to the clavicularanatomy, and many patients complain of postoperative implant-related discomfort. A total of 111 clavicles, both left andright sides, were examined to match two commonly used designs of anatomical pre-contoured superior anterior clavicleplates, with and without lateral extension. The anteroposterior (AP) plane congruence of the plate to the underlying bone, thevertical gap between the bone and plate, and the length of the plate that was off the bone either anteriorly and/or posteriorlyat both ends of the clavicle were measured. The scoring system was used to determine the fit of the implant on the clavicle asanatomic, good, or poor. We found that the maximum superior bow of the clavicle was lateral to the midline by 30.75 mmand 30.5 mm on the right and left sides, respectively. The magnitude of the bow was 4.28 mm and 4.46 mm on the right andleft sides, respectively. We also found that the plate was a poor fit in 75.86% of cases on the left side and 73.5% of cases on theright side. Manipulating the plates during surgery was very difficult in the AP plane.

        Study of frontal and ethmoid sinus of sinonasal complex along with olfactory fossa: anatomical considerations for endoscopic sinus surgery

        Kusum R Gandhi,Sumit Tulshidas Patil,Brijesh Kumar,Manmohan Patel,Prashant Chaware 대한해부학회 2023 Anatomy & Cell Biology Vol.56 No.2

        The Functional endoscopic sinus surgery through transnasal approach is a common modality of treatment fordisorders of the nasal cavity, paranasal air sinuses as well as cranial cavity. The olfactory fossa (OF) is located along the superior aspect of cribriform plate which varies in shape and depth. This variable measurement of the depth of OF is mostly responsible for greater risk of intracranial infiltration during endoscopic procedures in and around the nasal cavity. The morphology of frontal and ethmoid sinus (ES) vary from simple to complex. This cadaveric study is planned to improve the ability of the otolaryngologist, radiologist to understand the possible morphological variations and plan steps of less invasive “precision surgery” to have a safe and complication free procedures. A total of 37 human head regions were included in the study. For classification of OF, Modified Kero’s classification was used. The size, shape and cells of frontal and ES were noted. We found, type II (60.8%) OF was more common followed by type I (29.7%) than type III (9.5%). The shape of frontal sinus was comma shaped (55.4%) followed by oval (18.9%) than irregular (16.2%). Most common two cells type of ES was seen in 50.0% of both anterior and posterior ES. Out of 74 ES, 8.1% of Onodi cells and 14.9% of agger nasi cells were seen.
