RESUMEN
PURPOSE: The selection of perioperative antibiotics for prevention of surgical site infection (SSI) is often limited by the presence of a reported penicillin allergy. The purpose of this study was to determine if oral and maxillofacial surgery patients who report allergy to penicillin are at an increased risk of developing SSI. METHODS: A retrospective cohort study was performed of patients who underwent oral and maxillofacial surgical procedures in the operating room setting at a single institution between 2011 and 2018. The following categories of procedures were investigated: dentoalveolar, orthognathic, orthognathic with third molar extraction, pathology and reconstruction, and temporomandibular joint. The primary predictor and outcome variables were reported penicillin allergy and surgical site infection, respectively. Bivariate and multiple logistic regression analysis were performed. P < .05 was considered to be significant. RESULTS: The cohort was composed of 2,058 patients of which 318 (15.5%) reported allergy to penicillin. Beta-lactam antibiotics were administered less frequently to penicillin allergic patients perioperatively compared with those without penicillin allergy (7.9 vs 97.1%, P < .001), while clindamycin was more commonly administered (76.4 vs 2.5%, P < .001). Clindamycin was associated with a higher SSI rate compared with beta-lactam antibiotics (5.6 vs 1.4%, P < .001). Penicillin allergy was significantly associated with SSI at an adjusted odds ratio of 2.61 (95% CI 1.51 to 4.49, P = .001). After holding perioperative antibiotic usage equal between the 2 groups, penicillin allergy per se was no longer associated with SSI (P = .901), suggesting that the outcome was mediated by antibiotic selection. CONCLUSIONS: Penicillin allergy was associated with development of SSI due to receipt of non-beta-lactam antibiotics as perioperative prophylaxis. Formal allergy evaluation should be considered for patients with putative penicillin allergy.

PURPOSE: Heterotopic ossification (HO) is defined as bone where it does not belong and as the abnormal presence of calcifications within soft tissues or joints. The purpose of this study was to answer the following clinical question: Are there identifiable risk factors associated with HO in and around the temporomandibular joint (TMJ)? METHODS: We designed a retrospective review of patients seen at the Department of Oral and Maxillofacial Surgery, Massachusetts General Hospital, between January 1985 and December 2019 and diagnosed with HO involving the TMJ. Variables studied included demographic factors, medical history including hereditary conditions, and specific TMJ history including past interventions. The primary outcome variable was the diagnosis of HO based on radiographic findings using the classification system described by Turlington and Durr. Inclusion criterion was clinical or radiographic evidence of TMJ HO. RESULTS: A total of 67 patients met the inclusion criteria. There were 48 females and 19 males (2.5:1) with an average age of 44.1 ± 16.7 years (range, 5-76 years). Risk factors associated with TMJ HO included musculoskeletal disease, psychiatric illness, history of trauma or previous TMJ surgeries, and congenital conditions. Of these, a history of nonsurgical TMJ therapy (odds ratio [OR], 3.5; P < .00) was most closely associated with HO. This was followed by male sex (OR, 3.1; P = .001), other craniofacial or musculoskeletal surgeries (OR, 2.4; P = .004), TMJ surgeries (OR, 1.9; P = .012), and neurogenic injury (OR, 1.8; P = .018). The results also demonstrated that patients diagnosed with TMJ HO were medically complex, with 86.6% presenting with other systemic conditions. CONCLUSION: This study identifies several risk factors which differ from those reported in the orthopedic literature. The Turlington and Durr classification is only partially helpful in clinical decision-making and needs to include HO associated with TMJ alloplasts and autogenous bone grafts (eg, costochondral grafts).

PURPOSE: To review the demographic data, presenting symptoms, location, radiographic findings, treatment, and prognosis of pediatric jaw lesions in children treated at a single academic institution. PATIENTS AND METHODS: A retrospective medical record review was undertaken of patients younger than 18 years who presented to the Massachusetts General Hospital for Children between 2006 and 2018 with a primary jaw lesion. RESULTS: About 164 patients were identified. The most common lesions were giant cell tumors (n = 25), odontogenic keratocysts (n = 24), simple bone cysts (n = 19), odontomas (n = 17), fibrous dysplasia (n = 11), and dentigerous cysts (n = 11). Fifty-one patients (30.7%) were asymptomatic. About 94% were referred by their dentist, outside oral and maxillofacial surgeon or orthodontist. Most common presenting symptoms were swelling (66.9%), pain (32.5%), tooth mobility (17.5%), and neurosensory change (6.6%). Mandibular location was most common (72.3%). Radiographically, most were well-circumscribed radiolucencies with mean size of 2.9 cm (range, 0.7 to 15.6). Treatment varied from excisional biopsy to wide composite resection. Mean follow-up time was 38 months (range, 1 to 204). Recurrence was found in 21%. CONCLUSIONS: Pediatric jaw lesions are often asymptomatic and discovered incidentally by dental practitioners on routine examination. Clinical features (age, gender, location, and radiographic appearance) can help narrow the differential and expedite treatment. It is important that clinicians involved in the care of children be familiar with the wide differential diagnosis and management considerations of primary jaw lesions.

ABSTRACT: The purpose of this study is to estimate the incidence of fixation-related complications following ultrasound-activated biodegradable osteosynthesis (UBO) in the treatment of craniosynostosis. The authors searched MEDLINE, PubMed, Embase, Google Scholar, and Cochrane Library from January 2005 to January 2020 for clinical studies reporting the use of UBO for fixation in the treatment of craniosynostosis. The primary outcome was the incidence of fixation-related complications, including unstable fixation; swelling, plate visibility, or palpability; infection; inflammation, sinus formation, and discharge; implant exposure; reoperation or implant removal. The pooled incidence rates were estimated using random-effects models. Of 155 studies identified, 10 were included, representing 371 patients. Forty-six (12.4%) patients presented fixation-related complications. The incidence rates of swelling/visibility/palpability, infection, and reoperation/implant removal were pooled based on the available data. The pooled incidence rate of chronic swelling/visibility/palpability was 0.21 (95% confidence interval [CI], 0.05-0.43). Sensitivity analysis by omitting the outlier study demonstrates that the incidence of swelling/visibility/palpability was 0.07 (95% CI, 0.04-0.11). The pooled incidence rate of infection and reoperation/implant removal was 0.07 (95% CI, 0.01-0.16) and 0.04 (95% CI, 0.01-0.09), respectively. Results show that although UBO can provide stable fixation, chronic swelling/visibility/palpability, infection, and reoperation for removal are not uncommon. Based on the literature, the authors recommend judicious use of UBO in patients with large frontorbital advancement and in the area of the coronal suture or other sites with thin overlying skin/subcutaneous tissue. The high possibility of chronic swelling/palpability/visibility during degradation, needs to be discussed preoperatively.

PURPOSE: Although osteoporosis is associated with increased risks of complications of fracture fixation in the orthopedic literature, the association between local bone quality (LBQ) and complications of facial fracture fixation is unknown. The authors aim to identify that if decreased LBQ is an independent risk factor for complications following facial fracture fixation? METHODS: The authors conducted a prospective cohort study on patients over age of 50 years who underwent open reduction and rigid internal fixation for facial fractures. The primary predictor was LBQ (low or normal), decided by a combination of 3 panoramic indices. Other predictors included age, gender, body mass index (BMI), comorbidities, trauma-related characteristics, etc. The outcome variable was the presence of hardware-related, fracture-healing, wound, or neurosensory complications during 2-year follow-up. Univariate and multivariate regressions were performed to identify any significant association between predictor and outcome variables. RESULTS: The sample was composed of 69 patients (27 females) with an average age of 58.6â±â8.6 years and BMI of 25â±â3.8. Low-LBQ patients were significantly older, more females, had lower BMI, mainly injured from falls, had more complications compared to their normal-LBQ counterparts. However, multivariable logistic regressions demonstrated that only age (adjusted OR: 1.12, Pâ=â0.031, 95% CI: 1.01, 1.23) and diabetes (adjusted OR: 12.63, Pâ=â0.029, 95% CI: 1.3, 122.53) were significantly associated with overall complications after confounding adjustment. CONCLUSIONS: The results of the present study indicate that reduced LBQ is not an independent risk factor for complications following facial fracture fixation. The increased risk of complications in low-LBQ patients is more likely to be attributed to other age-related comorbidities such as diabetes. Therefore, the authors recommend detailed workup and good control of comorbidities in elderly trauma patient.

ABSTRACT: This meta-analysis aimed to provide an up-to-date comparison of donor site morbidity (DSM) between patients who underwent head and neck reconstruction with Anterolateral thigh (ALT) and radial forearm free (RFF) flaps. We searched the PubMed, Web of Science, EMBASE, and Cochrane Library databases to identify studies that compared DSM between ALT and RFF patients. Study quality was assessed using the Newcastle-Ottawa Scale. The pooled odds ratio (OR) of each DSM between ALT and RFF patients was estimated using a random- or fixed-effect model depending on the degree of interstudy heterogeneity. Sensitivity and subgroup analyses were performed if substantial heterogeneity was detected. Eighteen cohort studies with 1,018 patients (535 ALT and 483 RFF patients) were included. Compared with RFF, ALT were associated with lower risks of wound dehiscence (ORâ=â0.2, 95%CI: 0.10-0.42, Pâ<â0.01), strength impairment (ORâ=â0.18, 95%CI: 0.07-0.47, Pâ<â0.01), and movement impairment (ORâ=â0.19, 95%CI:0.07-0.49, Pâ<â0.01). A subgroup analysis showed that ALT were associated with a lower risk of donor site numbness among patients undergoing tongue reconstruction (ORâ=â0.05, 95%CI: 0.01-0.25, Pâ<â0.01), but not among all patients undergoing head and neck reconstruction. The pooled ORs of other DSMs demonstrated no significant difference between ALT and RFF patients. ALT are superior to RFF for head and neck reconstruction in terms of donor site wound dehiscence, strength impairment, movement impairment, and for tongue reconstruction specifically in terms of donor site numbness. No significant differences in the incidence of donor site hematoma/seroma, infection, or dissatisfaction with donor site appearance were identified between ALT and RFF patients.

BACKGROUND: Facial thread-lifting (FTL) has gained more popularity, but the incidences of complications following FTL remain controversial. We aimed to perform a meta-analysis and systematic review to estimate the incidences of complications and to compare the short- and long-term satisfaction rates following FTL. METHODS: We searched PubMed, Web of Science, Embase and Cochrane library for eligible studies. The primary outcome was the incidences of complications following FTL. The secondary outcome was the satisfaction rate immediately and 6-month after FTL. The pooled incidences of complications and 95% confidence intervals were estimated using random-effects models. RESULTS: A total of 26 studies were included in this meta-analysis. Swelling was the most commonly reported complication with a pooled incidence of 35%, followed by skin dimpling (10%), paresthesia (6%), thread visibility/palpability (4%), infection (2%), and thread extrusion (2%). Absorbable threads were associated with a significantly lower risk of paresthesia (3.1% vs. 11.7%) and thread extrusion (1.6% vs. 7.6%) than non-absorbable threads. Patients older than 50 years had a significantly higher risk of dimpling (16% vs. 5.6%) and infection (5.9% vs. 0.7%) than their younger counterparts. In addition, the pooled long-term satisfaction rate was significantly decreased compared to it immediately after FTL (88% vs. 98%). CONCLUSION: Non-absorbable threads and older age of patients are associated with higher risks of complications. Therefore, we recommend a judicious use of non-absorbable threads and FLT in older patients. Furthermore, it should be discussed with patients preoperatively that the rejuvenation effect of FTL may not maintain in the long-term.

PURPOSE: Sublingual gland tumors are rare. We sought to define the general features of sublingual gland tumors for clinical reference. In addition, we evaluated whether it would be safe to speculate that â¼90% sublingual gland tumors will be malignant and that â¼90% of those malignant tumors will be adenoid cystic carcinoma. MATERIALS AND METHODS: In the present study, we have reported data from a pleomorphic adenoma case of the sublingual gland and a case series of sublingual gland tumors. Global data of sublingual gland tumors were retrieved. The cases pathologically identified as either benign or malignant tumors of the sublingual gland were included. The demographic, pathologic, and treatment features were analyzed. RESULTS: Data from 1 recent case of pleomorphic adenoma of the sublingual gland and a 21-case series of sublingual gland tumors were retrieved. A total of 839 cases of sublingual gland tumors were analyzed in the present study. The most commonly encountered age group was 40 to 59 years (47.6%). Of the 367 patients with gender specified, 178 were men (48.5%) and 189 were women (51.5%). Malignant tumors predominated (n = 722 cases; 86.1% of 839). Most malignant tumors were adenoid cystic carcinoma (n = 376), just greater than one half (52.1%) of all malignant tumors. Surgery was the only reported treatment method for the benign tumors. The most common treatment methods for the 164 explicit malignant tumors were surgery plus radiotherapy for 82 patients (50%), followed by surgery alone for 70 patients (42.7%). CONCLUSIONS: To date and to the best of our knowledge, the present study is the most comprehensive study on the demographic, pathologic, and treatment features of global sublingual gland tumors. These findings have shown that â¼90% of sublingual gland tumors will be malignant. However, the assumption that â¼90% malignant sublingual gland tumors will be adenoid cystic carcinoma is incorrect, which could be a new critical clinical reference.

PURPOSE: To the best of our knowledge, no study has reported pediatric jaw lesions according to the latest World Health Organization (WHO) classification of head and neck tumors. We reviewed the spectrum of benign pediatric jaw lesions treated at the Massachusetts General Hospital during a 13-year period according to the 2017 WHO classification. PATIENTS AND METHODS: We implemented a retrospective cohort study of patients younger than 18 years old with benign bony lesions. The primary predictor variable was the histopathologic diagnosis, grouped into odontogenic tumors (OTs), non-OTs, and odontogenic cysts. The primary outcome variables were the incidence of recurrence and the interval to recurrence. Other outcome variables included symptoms, radiographic findings, and treatment modalities. Descriptive statistics were computed. Kaplan-Meier analyses and Cox regressions were performed. RESULTS: The sample included 131 patients (58 males and 73 females; mean age, 12.6 ± 3.7 years) with 14 pathologic diagnoses. These were grouped as follows: non-OTs (n = 67), OTs (n = 36), and odontogenic cysts (n = 28). Odontogenic cysts were predominantly radiolucent, unilocular, and well-circumscribed cysts compared with the OTs and non-OTs (P < .05). Enucleation was the most commonly performed surgical procedure (72.5%). Adjuvant nonoperative procedures included cryotherapy for 10 patients, interferon therapy for 9 patients, and chemotherapy with denosumab for 3 patients to treat aggressive tumors. The overall incidence of recurrence was 0.77/100 person-years. The Cox hazard ratio of non-OTs/OTs was 3.1 (P = .13) and cysts/OTs was 4.3 (P = .075). Neither the incidence of recurrence nor the interval to recurrence among the 3 groups showed significant differences. A high incidence of recurrence was noted for aggressive central giant cell tumors (39.1%) and odontogenic keratocysts (40%) during a median follow-up of 3 years. CONCLUSIONS: Although pediatric jaw lesions are uncommon, symptoms such as swelling could indicate potential pathologic findings and require panoramic examination. Management of pediatric jaw lesions should consider the biologic behavior of the lesion, maxillofacial development, and growth. Enucleation combined with pharmacologic therapy is a promising strategy for the management of aggressive central giant cell tumors in children.

PURPOSE: This study sought to answer the following question: Do patients with different mandibular plane angles (MPAs) have a different time to relapse after mandibular advancement with bilateral sagittal split osteotomy? MATERIALS AND METHODS: We performed a retrospective cohort study of patients who underwent bilateral sagittal split osteotomy advancement at Massachusetts General Hospital between 2005 and 2017. The primary predictor variable was MPA, categorized as low (<25°), medium (between 25° and 35°), or high (>35°). The outcome variable was time to relapse (≥2-mm posterior change at the B point). Other covariates included gender, age, temporomandibular joint symptoms, bimaxillary surgery, direction of mandibular rotation, magnitude of advancement, genioplasty, and fixation method. Time to relapse was estimated using the Kaplan-Meier method. Cox and parametric regressions for interval-censored data were performed. P < .05 was considered statistically significant. RESULTS: The sample was composed of 58 patients (40 female patients), with a mean age of 26.1 ± 4.9 years, grouped as follows: low MPA, n = 15; medium MPA, n = 26; and high MPA, n = 17. Clinically significant relapse was found in 18 patients (31%). Age, temporomandibular joint symptoms, counterclockwise rotation, and magnitude of advancement were statistically significantly different among the 3 groups. When we assessed time to relapse, the Kaplan-Meier method showed that high-MPA patients had a longer mean time at risk and higher estimated probabilities of relapse at different time points compared with low- and medium-MPA patients (P < .05). However, this association was not significant in Cox and parametric regressions. CONCLUSIONS: Our results suggest that clinically significant relapse was found during the first postoperative year in low-MPA patients and from 2 to 5 years postoperatively in high-MPA patients. Multivariate regression analyses did not show a significant association between MPA and time to relapse, suggesting that other covariates may play a role in the observed time to relapse.

PURPOSE: Although the minor salivary gland biopsy (MSGB) is a major criterion for the diagnosis of Sjögren syndrome (SS), multiple studies have outlined difficulties in standardization. The purpose of this study was to answer the following question: in all patients referred for MSGB, did strict application of focus scoring criteria alter the sensitivity of and predictive value of the MSGB in the diagnosis of SS compared with the initial interpretation? MATERIALS AND METHODS: The authors designed a cross-sectional study of patients referred to the Massachusetts General Hospital Department of Oral and Maxillofacial Surgery (Boston, MA) over a 5-year period for MSGB. The primary predictor variable was the MSGB focus score. The primary outcome variable was the SS diagnosis. The newly established SS diagnosis status results were compared with the initial SS diagnoses. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated. Other relevant variables of interest, such as size of glandular tissue harvested and associated signs and symptoms, also were documented. The primary predictor variable was the MSGB focus score and the primary outcome variable was the SS diagnosis (positive or negative). RESULTS: Seventy-three patients met the inclusion criteria. The mean age was 48.5 years (range, 19 to 71 yr) and 64 were women (87.6%). The authors' previous study using initial pathology reports yielded 80.0% sensitivity, 87.5% specificity, 57.1% PPV, and 95.5% NPV. The present review of the MSGB using strict focus scoring guidelines yielded 95.4% sensitivity, 76.4% specificity, 63.6% PPV, and 97.5% NPV. CONCLUSIONS: The MSGB is an important major criterion in establishing a diagnosis of SS. Application of strict focus scoring guidelines when reviewing the MSGB yielded a sensitivity far greater than initially reported in this group. Difficulties with interpretation are discussed. Future studies will focus on improvement of interpretation and immunohistochemical aids in diagnosis.

PURPOSE: This study investigated whether patients with documented obstructive sleep apnea (OSA) who have a decrease in apnea-hypopnea index (AHI) score and self-reported symptoms after maxillomandibular advancement (MMA) with genial tubercle advancement (GTA) also have a change in their medical comorbidity profile a minimum of 2 years postoperatively. Changes in the quantity of medical diagnoses, quantity of prescription medications, and average weight and body mass index (BMI) were assessed. PATIENTS AND METHODS: This is a retrospective cohort study of patients with a diagnosis of OSA (AHI score >5 on polysomnogram [PSG]) treated at the Massachusetts General Hospital (Boston, MA) with MMA and GTA from 2001 through 2015. Patients were identified through the oral and maxillofacial surgery patient data registry. Inclusion criteria were the availability of complete clinical records and requisite follow-up time. The primary predictor variable was operative status (preoperative or postoperative). The primary outcome variables were comorbidities reported to be associated with OSA and identified in the authors' previous study (J Oral Maxillofac Surg 76:1999.e1, 2018). Two-tailed paired t tests were used for continuous variables and χ2 or Fisher exact tests were used for categorical variables. RESULTS: Forty-six patients (39 men, 7 women) met the inclusion criteria. Average weight (206.7 ± 42.4 lb preoperatively; 213.8 ± 41.7 lb postoperatively; P = .014) and average BMI (30.0 ± 5.7 kg/m2 preoperatively; 30.9 ± 5.3 kg/m2 postoperatively; P = .041) significantly increased in patients postoperatively. No meaningful changes in the number of medical diagnoses or number of prescription medications were noted. Stratification of patients by BMI showed significant increases in weight (188.6 ± 21.5 lb preoperatively; 200.1 ± 27.9 lb postoperatively; P = .0085) and BMI (27.1 ± 1.44 kg/m2 preoperatively; 28.9 ± 3.52 kg/m2 postoperatively; P = .013) only in "overweight" patients. No other parameters were found to be relevant. CONCLUSIONS: Subjective improvement in OSA symptoms was reported by all patients and objective PSG improvement was reported for 71% of those evaluated. However, no relevant changes in comorbidity profile were found, suggesting that the medical conditions commonly observed with OSA are likely of multifocal etiology.

PURPOSE: We sought to compare cricothyroid membrane puncture-guided tracheostomy (CMPGT) with surgical cricothyroidotomy (SC) and percutaneous tracheostomy with Griggs' guidewire dilating forceps (GWDF) for establishing an emergency airway in a porcine model. We hypothesized that CMPGT would be associated with a shorter time to ventilation and more rapid restoration of oxygenation. MATERIALS AND METHODS: We implemented a small pilot animal study. Eighteen miniature pigs were randomly assigned to undergo CMPGT, SC, or GWDF. The predictor variable was the technique used. The primary outcome variable was time to ventilation. Other outcome variables were efficiency of oxygenation restoration, procedure duration, and procedure-related complications. The data were assessed using 1-way analysis of variance and Bonferroni correction. The oxygen saturation (SpO2) changes over time were graphed using a time-series line plot. Statistical significance was set at P < .05. RESULTS: Airways were successfully established in all 18 pigs. SC (68 ± 4 seconds) showed the shortest procedure duration compared with GWDF (95 ± 3 seconds) and CMPGT (96 ± 4 seconds); however, the time to ventilation using CMPGT (21 ± 2 seconds) was significantly shorter than that with SC (68 ± 4 seconds) and GWDF (95 ± 3 seconds) (P < .01). Spo2 in each group increased postoperatively, reaching 95% at 120 seconds, 131 seconds, and 144 seconds in the CMPGT, SC, and GWDF groups, respectively. The slope of the ascending phase of the Spo2 curve was 0.38 for CMPGT, 0.42 for SC, and 0.53 for GWDF (P < .05). Two pigs in each group had minor intraoperative bleeding, and 1 pig in the SC group had moderate bleeding. CONCLUSIONS: The results of this animal study suggest that CMPGT is a time-efficient and safe technique for emergency airway access that allows for a more rapid return of ventilation and obviates conversion to definitive tracheostomy. Further cadaveric study is ongoing.

PURPOSE: To review cases of suppurative osteomyelitis of the jaws treated at the Massachusetts General Hospital (Boston, MA) over a 10-year period, evaluate specifics of disease presentation, and answer the clinical question: are there identifiable variables associated with treatment outcome? MATERIALS AND METHODS: A retrospective cohort study was completed using patients treated for suppurative osteomyelitis of the jaws at the Massachusetts General Hospital from April 2006 to October 2016. Inclusion criteria were a diagnosis of suppurative osteomyelitis of the jaw, age older than 18 years, and complete medical records. Patients with nonsuppurative disease, radiation history, or antiresorptive exposure were excluded. Candidate variables included demographic information, medical and dental history, presenting signs and symptoms, and radiologic and laboratory findings. The outcome variable was successful treatment, defined as resolution of symptoms and radiographic evidence of healing after initial treatment. Appropriate statistical analyses were performed with significance set a P value less than .05. RESULTS: Forty-two patients met the inclusion criteria. Mean age was 53 years (range, 20 to 80 yr) and 26 were women (62%). Common comorbidities included cardiovascular disease (52%), tobacco use (45%), and psychiatric disorders (45%). Pain (90%), swelling (86%), and neurosensory change (50%) were the most common findings. Common microbacterial isolates included Streptococcus milleri (74%) and coagulase-negative Staphylococcus species (43%), which showed marked antibiotic resistance. Surgical debridement was the most common intervention (93%). Successful treatment was found in 86%. Of 6 persistent cases, 4 resolved with a second debridement and continued antibiotics and 2 required resection. Increased white blood cell (WBC) count at presentation (P = .005) and associated psychiatric diagnoses (P = .037) were statistically associated with unsuccessful initial treatment. CONCLUSION: The results of this study indicate that antibiotic resistance is commonly encountered in this patient population, although it was not associated with unsuccessful outcome. Patients presenting with increased WBC count and concurrent psychiatric comorbidities required protracted treatment.

PURPOSE: Obstructive sleep apnea (OSA) patients with retrognathia and measurable anatomic airway determinants may represent a subset of OSA patients and have distinct comorbidity profiles. Our aim was to compare the medical comorbidities of OSA patients managed surgically with maxillomandibular advancement with those of nonsurgical patients. PATIENTS AND METHODS: In this cross-sectional retrospective study, patients for both cohorts were identified through the Massachusetts General Hospital oral and maxillofacial surgery data registry and the Massachusetts General Hospital Research Patient Data Registry. The inclusion criteria consisted of clinical records documenting body mass index (BMI), apnea-hypopnea index, respiratory disturbance index, and/or oxygen nadir. The primary predictor variable was the treatment modality chosen: surgical (maxillomandibular advancement) or nonsurgical. Demographic information and OSA parameters were evaluated. The primary outcome variable was the number of documented comorbidities in each group. Two-sample t tests were used for continuous variables, whereas χ2 or Fisher exact tests were used for categorical variables. RESULTS: The nonsurgical cohort consisted of 71 patients (67.6% men), and the surgical cohort consisted of 51 patients (84.3% men). Comparison of descriptive characteristics showed that the nonsurgical cohort had a higher average age (49 ± 9.4 years) than the surgical cohort (41 ± 10.7 years, P < .001). In addition, a higher average BMI was present in the nonsurgical group (42.3 ± 11.9 in nonsurgical group vs 29.7 ± 5.5 in surgical group, P < .001). Polysomnogram parameters were comparable with the exception of a higher Epworth Sleepiness Scale score in the surgical cohort (15.5 ± 5.30 in surgical group vs 9.90 ± 6.80 in nonsurgical group, P = .005). The nonsurgical cohort had a higher total number of comorbidities (7 ± 4 in nonsurgical group vs 4 ± 3 in surgical group, P < .001). Hypertension, cardiovascular disease, hyperlipidemia, pulmonary hypertension, obstructive pulmonary disease, and type 2 diabetes mellitus had higher prevalences within the nonsurgical group. CONCLUSIONS: The results of this study suggest that nonsurgically managed OSA patients tend to have more complex medical comorbidity profiles than those managed surgically. Obesity (BMI >30) was more prevalent in the nonsurgical cohort, which may be contributory. The additive contribution of OSA needs to be further elucidated.

PURPOSE: This study assessed the antibiotic resistance profile in patients with severe orofacial infections treated at a single institution from 2009 through 2014. Factors contributing to resistance were studied. The resistance profile was compared with that of a cohort of similar patients treated a decade previously to identify changes in antibiotic resistance. In addition, the effect of antibiotic resistance on in-hospital course was studied. MATERIALS AND METHODS: This was a 5-year retrospective cohort study. Patients were identified through the oral and maxillofacial surgery data registry. Inclusion criteria were patients treated for orofacial infection requiring hospital admission, surgical drainage, and availability of complete medical, surgical, and microbiological data. Patients with incomplete data or treated as outpatients or nonsurgically were excluded. Sixty patient charts were identified for review. Demographic data; medical, dental, and surgical histories; and hospital course and treatment specifics were obtained for each patient. Linear regression and logistic analyses were used to analyze the data. RESULTS: Men composed 60% of the cohort (mean age, 45 yr). Average hospital stay was 5.5 days. Penicillin resistance was found in 32.5% of aerobic isolates and clindamycin resistance was found in 29.3%. Streptococcus viridans and Staphylococcus species showed increased resistance to clindamycin and erythromycin compared with historic controls. Younger patient age, surgical history, and number of cultured aerobes showed a relevant correlation to antibiotic resistance. The need for changes in antibiotics, repeat surgical drainage, and increased serum urea nitrogen levels correlated with longer hospital stay. CONCLUSION: A serious increase in clindamycin and erythromycin resistance was found for S viridans and Staphylococcus species. Age, surgical history, and number of cultured aerobes showed a statistically meaningful correlation to antibiotic resistance. Presence of antibiotic resistance failed to show statistically relevant correlations to prolongation of hospital stay. Rather, the need for change in antibiotic regimen, the need for re-drainage, and increased serum urea nitrogen level were associated with longer hospital stay.

PURPOSE: Sjögren syndrome (SS), although commonly associated with xerostomia and xerophthalmia, can present with extraglandular manifestations that make definitive diagnosis difficult. The 2 leading diagnostic classification systems include a positive minor salivary gland biopsy (MSGB) result as a major inclusion criterion. The purpose of this study was to better define the role of the MSGB in establishing a diagnosis of SS in a cohort of referred patients. MATERIALS AND METHODS: This is a retrospective cohort study of patients referred to the Massachusetts General Hospital Department of Oral and Maxillofacial Surgery (Boston, MA) over a 5-year period to establish a diagnosis of SS. Inclusion criteria were complete information regarding presenting symptoms, reason for referral, and findings at MSGB. Incomplete records and referral for reasons other than presumptive SS resulted in exclusion. The MSGB and its role in definitive diagnosis based on accepted classification systems were evaluated for sensitivity, specificity, and positive and negative predictive values. Other variables of interest (demographics, pattern of referral, and symptomology) are described for the cohort. RESULTS: Eighty-seven patients met the inclusion criteria. The mean age was 48.3 years (range, 19 to 74 yr) and 75 were women (86.2%). Fifteen MSGB results (17.2%) were positive based on the focus score histologic criteria. In 12 of 15 cases, the positive MSGB result allowed for a definitive diagnosis (80%). In 3 cases, other criteria allowed diagnosis without the contribution of the MSGB (sensitivity of MSGB, 80.0%; specificity, 87.5%; positive predictive value, 57.1%; negative predictive value, 95.5%). CONCLUSION: The MSGB is an important contributor to a diagnosis of SS. When serology was negative, the MSGB often was the criterion that allowed the diagnosis to be established. It is the most frequently positive of the major criteria used by the 2 classification systems in current use.

Oral cavity metastasis of malignant tumors is extremely rare and accounts for only 1% of all malignant oral tumors. Renal cell carcinoma (RCC) can metastasize to any part of the body, with a 15% risk of metastasis to the head and neck region when the disease is disseminated and a 1% risk when it is not. RCC also is the third most common infraclavicular neoplasm that metastasizes to the oral cavity, after lung carcinoma in men and breast carcinoma in women. In the maxillofacial region, the nasal cavity and paranasal sinuses are the most commonly affected sites, followed by the oral cavity. This report describes the case of a 51-year-old man with a history of clear RCC presenting with 3 synchronous atypical metastases of this tumor to the maxillary gingiva, scalp, and distal phalanx of the fifth digit. Clinical findings, diagnosis, pathology, and treatment of these lesions are discussed. Metastasis of RCC should always be included in the differential diagnosis when a new oral and maxillofacial lesion appears in a patient with a history of RCC because the metastatic lesions can often present in a broad spectrum of forms. The rapid growth of these lesions should alert clinicians to avoid any delays in biopsy examination and subsequent treatment, which is usually palliative, because prognosis is usually poor.

Traumatic injuries to the lip are common, but injuries that require revascularization of the lower lip are infrequent and pose a major challenge to the reconstructive surgeon. This report describes the case of a 53-year-old woman who sustained a lower lip avulsion injury, a comminuted mandibular parasymphyseal fracture, and a hyoid bone fracture secondary to a bicycle accident. Trauma workup included computed tomographic angiography of the head and neck, which did not show vascular injury. Despite successful revascularization of the lower lip, on postoperative day 11 the patient developed a large internal carotid artery dissection and middle cerebral artery stroke. This case highlights the importance of careful postoperative monitoring after high-energy facial trauma, particularly in the setting of vascular and bony injuries.

PURPOSE: To determine the accuracy of incisional biopsy examination to diagnose oral lesions. MATERIALS AND METHODS: This retrospective cohort study was performed to determine the concordance rate between incisional biopsy examination and definitive resection diagnosis for different oral lesions. The study sample was derived from the population of patients who presented to the Department of Oral and Maxillofacial Surgery, Massachusetts General Hospital (Boston, MA) from January 2005 through December 2012. Inclusion criteria were the diagnosis of an oral lesion from an incisional biopsy examination, subsequent diagnosis from the definitive resection of the same lesion, and complete clinical and pathologic patient records. The predictor variables were the origin and size of the lesion. The primary outcome variable was concordance between the provisional incisional biopsy diagnosis and definitive pathologic resection diagnosis. The secondary outcome variable was type of biopsy error for the discordant cases. Incisional biopsy errors were assessed and grouped into 5 categories: 1) sampling error; 2) insufficient tissue for diagnosis; 3) presence of inflammation making diagnosis difficult; 4) artifact; and 5) pathologist discordance. RESULTS: A total of 272 patients met the inclusion criteria. The study sample had a mean age of 47.4 years and 55.7% were women. Of these cases, 242 (88.9%) were concordant when comparing the biopsy and final resection pathology reports. At histologic evaluation, 60.0% of discordant findings were attributed to sampling error, 23.3% to pathologist discrepancy, 13.3% to insufficient tissue provided in the biopsy specimen, and 3.4% to inflammation obscuring diagnosis. Overall, concordant cases had a larger average biopsy volume (1.53 cm(3)) than discordant cases (0.42 cm(3)). CONCLUSION: The data collected indicate an 88.9% diagnostic concordance with final pathologic results for incisional oral biopsy diagnoses. Sixty percent of discordance was attributed to sampling error when sampled tissue was not representative of the lesion in toto. Multiple-site biopsy specimens and larger-volume samples allowed for a more accurate diagnosis.
