Microbiology Alloplastic Total Joint Infections: A 20-Year Retrospective Study.

Purpose: Prosthetic joint infection (PJI) is a rare complication of temporomandibular joint replacement (TJR). This study evaluated TJR PJIs at the authors' institution over a 20-year period, including micro-organisms cultured, antibiotic resistance patterns, and intraoperative protocols of TJR.

Patients And Methods: Patients were identified using Current Procedural Terminology and International Classification of Diseases, Ninth Revision codes and surgical logs from January 1995 through 2015.

Is There a Difference in Cost Between Standard and Virtual Surgical Planning for Orthognathic Surgery?

Purpose: Virtual surgical planning (VSP) and 3-dimensional printing of surgical splints are becoming the standard of care for orthognathic surgery, but costs have not been thoroughly evaluated. The purpose of this study was to compare the cost of VSP and 3-dimensional printing of splints ("VSP") versus that of 2-dimensional cephalometric evaluation, model surgery, and manual splint fabrication ("standard planning").

Materials And Methods: This is a retrospective cohort study including patients planned for bimaxillary surgery from January 2014 to January 2015 at Massachusetts General Hospital.

Anesthesia Complications of Diazepam Use for Adolescents Receiving Extraction of Third Molars.

Purpose: To evaluate the safety of midazolam and diazepam for adolescents during third molar extraction and whether any differences in perioperative complications exist when using the 2 benzodiazepines alone or in combination.

Materials And Methods: A prospective study was performed in adolescents (<21 yr old) who underwent at least 1 third molar extraction by an oral and maxillofacial surgeon in the ambulatory setting from January 2001 through December 2010 using the Oral and Maxillofacial Surgery Outcomes System. The primary predictor variable was type of benzodiazepine used, divided into the total number of patients who received diazepam with or without midazolam.

Health Insurance Affects Head and Neck Cancer Treatment Patterns and Outcomes.

Purpose: The purpose of this study is to examine the effect of insurance coverage on stage of presentation, treatment, and survival of head and neck cancer (HNC).

Materials And Methods: A retrospective study was conducted using the Surveillance, Epidemiology, and End Results (SEER) program to identify patients diagnosed with HNC. The primary variable of interest was insurance analyzed as a dichotomous variable: Patients were considered uninsured if they were classified as "uninsured" by SEER, whereas patients were considered insured if they were defined by SEER as "any Medicaid," "insured," or "insured/no specifics.

Components of Patient Satisfaction After Orthognathic Surgery.

The purpose of this study was to compare overall patient satisfaction after orthognathic surgery with the following specific categories: appearance, functional ability, general health, sociability, and patient-clinician communication. A 16-question survey was developed and administered to include patients at either 6 or 12 months after orthognathic surgery between June 2013 and June 2014 at the University of Pennsylvania and Massachusetts General Hospital. The predictor variables included age, sex, type of procedure, medical comorbidities, intra- or postoperative complications, and presence of paresthesia.

Upper Airway Length is Predictive of Obstructive Sleep Apnea in Syndromic Craniosynostosis.

Purpose: Midfacial hypoplasia is a characteristic feature of the syndromic craniosynostoses and predisposes these patients to developing obstructive sleep apnea (OSA). The purpose of this study was to identify anatomic factors associated with airway obstruction in patients with syndromic craniosynostoses.

Materials And Methods: This was a retrospective cohort study.

Complications of Moderate Sedation Versus Deep Sedation/General Anesthesia for Adolescent Patients Undergoing Third Molar Extraction.

Purpose: To examine the complications resulting from moderate sedation versus deep sedation/general anesthesia for adolescent patients undergoing third molar extraction and determine whether any differences in complication risks exist between the 2 levels of sedation.

Materials And Methods: We performed a prospective study of the Oral and Maxillofacial Surgery Outcomes System from January 2001 to December 2010. The primary predictor variable was the level of sedation, divided into 2 groups: moderate sedation versus deep sedation/general anesthesia.

Oral and Maxillofacial Surgery Foundation Research and Fellowship Awards: A 26-Year Review at Massachusetts General Hospital and Harvard School of Dental Medicine.

Purpose: The purpose of this study was to review outcomes of the Oral and Maxillofacial Surgery (OMS) Foundation's funding awards to members of the OMS department at Massachusetts General Hospital (MGH) in terms of projects completed, abstracts presented, peer-reviewed publications, and career trajectories of recipients.

Materials And Methods: Data were collected from MGH and OMS Foundation records and interviews with award recipients. Primary outcome variables included 1) number of awards and award types, 2) funding amount, 3) project completion, 4) number of presented abstracts, 5) conversion from abstracts to publications, 6) number of peer-reviewed publications, 7) career trajectories of awardees, and 8) additional extramural funding.

Marital status and head and neck cancer outcomes.

Background: The objective of this study was to examine the effects of marital status on stage at presentation, receipt of treatment, and survival in patients with head and neck cancer (HNC).

Methods: The Surveillance, Epidemiology, and End Results database was used to analyze 51,272 patients who were diagnosed with HNC from 2007 to 2010. The impact of marital status on cancer stage at presentation, receipt of definitive treatment, and HNC-specific mortality (HNCSM) was determined using multivariable logistic and Fine and Gray competing-risks regression models, as appropriate.

Impact of African-American race on presentation, treatment, and survival of head and neck cancer.

Objectives: To determine the associations between African American race and stage at diagnosis, receipt of definitive therapy, and cancer-specific mortality among patients with head and neck cancer.

Materials And Methods: The Surveillance, Epidemiology and End Results (SEER) database was used to conduct a retrospective study on 34,437 patients diagnosed with head and neck cancer from 2007 to 2010. Multivariable logistic regression analyses were applied to determine the impact of race on cancer stage at presentation (metastatic vs.

Increasing value in plagiocephaly care: a time-driven activity-based costing pilot study.

Background: Process management within a health care setting is poorly understood and often leads to an incomplete understanding of the true costs of patient care. Using time-driven activity-based costing methods, we evaluated the high-volume, low-complexity diagnosis of plagiocephaly to increase value within our clinic.

Methods: A total of 59 plagiocephaly patients were evaluated in phase 1 (n = 31) and phase 2 (n = 28) of this study.

The value of postoperative visits for third molar removal.

Purpose: The clinical follow-up visit after third molar extraction has been cited as time consuming and of little benefit to patients. Although telephone follow-up has the potential to add value to the surgical management of third molars, sparse information exists on the financial context of this alternative. The purpose of this study was to show the change in value of third molar extraction with telephone follow-up through 1) measurement of the postoperative complication rate and 2) costs of telephone versus clinical follow-up.

The role of phenotyping in chronic prostatitis/chronic pelvic pain syndrome.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a chronic pain syndrome identified by the presence of noninfectious pelvic or perineal pain lasting longer than 3 months. Current diagnoses and treatments for the syndrome solely depend on and target symptoms, respectively. Thus far, the mechanistic disturbances responsible for the pathogenesis of CP/CPPS have remained largely elusive and treatments, and therefore, continue to be ineffective.
