Sinus culture differences in patients with radiographic evidence of odontogenic disease.

PURPOSE: Odontogenic sinusitis is a well-known entity with a different pathogenesis than chronic rhinosinusitis. Nonspecific symptoms can make diagnosis difficult. This study aims to compare culture results between patients with and without computed tomography findings indicative of possible odontogenic disease. MATERIALS AND METHODS: This was a retrospective cohort study in which patients undergoing endoscopic sinus surgery for chronic sinusitis over a three-year period at a single institution were reviewed. CT imaging was reviewed for evidence of dental disease, specifically periapical lucency, dehiscence of the floor of the maxillary sinus, oroantral fistula, or foreign body. Culture results were then assessed and compared between groups with CT evidence of a possible odontogenic source to those without. RESULTS: Overall, 231 patients were evaluated. 92 patients (39.8 %) were found to have evidence of a likely odontogenic source on CT. Cultures were available for 118 of 231 patients (51.1 %). Patients with CT signs of odontogenic disease were significantly more likely to grow Proteus mirabilis (p = 0.018) and Klebsiella pneumoniae (p = 0.037) on culture. Patients without CT signs of odontogenic sources were significantly more likely to grow Pseudomonas aeruginosa (p = 0.009). Of note, patients with CT findings concerning for an odontogenic source were also more likely to grow fungi other than Aspergillus and Mucor species on culture (p = 0.004). CONCLUSION: Patients with CT findings concerning for an odontogenic source of sinus disease showed differences in culture results that could be important in differentiating pathogenesis of sinus disease.

Routine Contrasted Chest CT Accurately Identifies Anatomic Variations of the Proximal Subscapular System.

OBJECTIVE: The vascular anatomy of the proximal subscapular artery has been previously classified into 2 major types depending on the presence of a common subscapular trunk. The purpose of this study was to determine the utility, reliability, and cost of routine chest imaging to identify these anatomical variations. METHODS: Data were collected retrospectively at a tertiary medical center for patients who were undergoing CT chest for various indications between October 2019 and October 2020. Two independent and blinded readers interpreted CT chest with contrast of 52 patients for a total 104 sides. RESULTS: The proximal branching pattern of the subscapular system was identified to have a common trunk in 99 (95%) sides. The remaining five sides (5%) demonstrated two arterial pedicles; with one patient exhibiting the variant anatomy bilaterally. CONCLUSION: Preoperative CT chest with contrast can accurately identify anatomic variation of the subscapular vascular system. For complex reconstruction requiring a single anastomosis in the vessel depleted neck, preoperative imaging can assure selection of a type I vascular anatomy of the proximal subscapular system. Preoperative imaging with contrasted CT has value in assessing this anatomy when planning for chimeric flaps involving circumflex scapular and thoracodorsal arteries.

Functional Outcomes After the Sacrifice of Mandibular Condyle Using Fibula Free Flap for Immediate Surgical Reconstruction.

Introduction Head and neck cancer with mandibular invasion often necessitates composite resection, leading to defects requiring reconstruction. Microvascular fibula free flap (FFF) surgery is a common approach for this purpose. In this study, we focus on our experience with condyle sacrifice, emphasizing treatment outcomes and functional results. Additionally, we highlight a contemporary perspective by discussing surgical techniques and radiographic outcomes based on a 3D analysis of neo-condyle placement on CT imaging. Methods We studied 23 patients who had undergone segmental mandibulectomy requiring FFF reconstruction between 2009 and 2020. These were all performed by the same surgeon (M.M.) at an academic tertiary care center. Twenty-three reconstructions included condyle sacrifice. Retrospective chart review was performed with a focus on treatment, functional outcomes, and surgical technique. Results A total of 23 patients were included in the study group (13 females and 10 males) with a mean age of 58.1 years. The most common surgical indication was for oncologic purposes (n=9; 39.1%). Twenty (87%) patients required tracheostomy, and all were decannulated. In terms of surgical complications, two (8.7%) patients had a degree of arterial insufficiency and two (8.7%) developed delayed infections. The average inpatient stay was 5.61 days, with a subsequent average clinic follow-up after 16.9 days. CT or MRI imaging was available for 21 (91.3%) patients, showing 14 (66.7%) neo-condyles within the glenoid fossa. Fifteen (71.4%) patients had some element of anterior displacement (average=6.27 mm), and seven (33.3%) patients had a component of lateral displacement (average=2.23 mm). Three (13%) patients died during the follow-up period. Eighteen (90%) of the surviving patients returned to an oral diet within an average of 24.9 days. All patients returned to normal interincisal distance by 12 months. All FFFs, with and without complications, remained viable. Conclusion We achieved favorable oral function outcomes in the majority of our patients. Intriguingly, although radiographic evidence revealed anterior and/or lateral displacement of the neo-condyle, there was no observed correlation with the resumption of oral diet, trismus, or crossbite among these patients.

Morning report decreases length of stay in trauma patients.

BACKGROUND: Modern acute care surgery (ACS) programs depend on consistent patient hand-offs to facilitate care, as most programs have transitioned to shift-based coverage. We sought to determine the impact of implementing a morning report (MR) model on patient outcomes in the trauma service of a tertiary care center. METHODS: The University of Arkansas for Medical Sciences (UAMS) Division of ACS implemented MR in October 2015, which consists of the trauma day team, the emergency general surgery day team, and a combined night float team. This study queried the UAMS Trauma Registry and the Arkansas Clinical Data Repository for all patients meeting the National Trauma Data Bank inclusion criteria from January 1, 2011 to April 30, 2018. Bivariate frequency statistics and generalized linear model were run using STATA V.14.2. RESULTS: A total of 11 253 patients (pre-MR, n=6556; post-MR, n=4697) were analyzed in this study. The generalized linear model indicates that implementation of MR resulted in a significant decrease in length of stay (LOS) in trauma patients. DISCUSSION: This study describes an approach to improving patient outcomes in a trauma surgery service of a tertiary care center. The data show how an MR session can allow for patients to get out of the hospital faster; however, broader implications of these sessions have yet to be studied. Further work is needed to describe the decisions being made that allow for a decreased LOS, what dynamics exist between the attendings and the residents in these sessions, and if these sessions can show some of the same benefits in other surgical services.
