• Bisphosphonate-Related Osteonecrosis of the Jaw in Patients With Oral Bisphosphonate Exposure: Clinical Course and Outcomes.

  Authors: Felice S O'Ryan, Joan C Lo

  Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons.

  PURPOSE: To characterize the spectrum and outcomes of bisphosphonate-related osteonecrosis of the jaw (BRONJ) occurring with oral bisphosphonate therapy. MATERIALS AND METHODS: We assembled aPURPOSE: To characterize the spectrum and outcomes of bisphosphonate-related osteonecrosis of the jaw (BRONJ) occurring with oral bisphosphonate therapy. MATERIALS AND METHODS: We assembled a retrospective cohort of patients who had developed oral BRONJ according to the 2009 American Association of Oral and Maxillofacial Surgeons criteria and received care within Kaiser Permanente, Northern California, during 2004 to 2011. Patients with intravenous bisphosphonate exposure were excluded. The demographic factors, comorbidities, pharmacologic exposure, maxillofacial findings, and outcomes were ascertained from the clinical and radiologic records. RESULTS: We identified 30 cases of oral BRONJ (median age 77 years, 87% women). All had received oral bisphosphonate for osteoporosis/osteopenia (median duration 4.4 years, interquartile range 1.9 to 6.6). More than one half (57%) had comorbidities or relevant drug exposure, including rheumatoid arthritis, diabetes, glucocorticoid therapy, and disease-modifying antirheumatic medications. Extractions preceded BRONJ in 17 patients and trauma in 3; 10 developed BRONJ spontaneously. Overall, 83% had healed within 3 to 52 months, although the relative rate of healing varied by antecedent factor and/or the presence of comorbid conditions/exposures. Nearly all patients with trauma-related and spontaneous BRONJ healed within 1 year (median 7.0 and 7.5 months, respectively) compared with those developing BRONJ after extraction, in whom the median time to healing was 18 months (P < .0001). Patients with relevant comorbidities had a lower probability of healing (P = .0002) and a longer median time to healing (20 months) than patients without comorbidities (7.5 months). CONCLUSIONS: We found that postextraction patients and those with comorbid conditions/exposures showed refractory BRONJ with prolonged healing times. Practitioners should be aware that the BRONJ clinical course and outcome varies depending on the antecedent factor and comorbidity status.

MATERIALS AND METHODS: Twelve rabbits were randomly assigned to the sham control, radiotherapy control, nontransfected mesenchymal stem cells (MSCs), and MSCs transfected with BMP-2/7 groups. All rabbits, except those in the sham control group, received preoperative radiation of 9 Gy for 5 fractions. One month after radiotherapy, all rabbits underwent unilateral mandibular distraction at a rate of 0.9 mm/d for 11 days. At the end of active distraction, MSCs combined with bovine collagen were injected into the distraction zone. After 4 weeks of consolidation, the mandibular samples were collected and subjected to radiographic, microcomputed tomographic, and histologic examinations. RESULTS: By radiographic examination, animals injected with nontransfected MSCs or MSCs encoding BMP-2/7 exhibited more bone formation than the control groups. Histologic examination showed that the group with MSCs encoding BMP-2/7 had a more mature medullary cavity than the nontransfected MSCs group. CONCLUSIONS: MSCs encoding BMP-2/7 can increase bone healing in irradiated mandibular bone.

  To assess the success and marginal bone loss, after 1 year of loading, of implants placed in anatomic buttresses of atrophic maxillae to rehabilitate patients with combination syndrome. A case seriesTo assess the success and marginal bone loss, after 1 year of loading, of implants placed in anatomic buttresses of atrophic maxillae to rehabilitate patients with combination syndrome. A case series retrospective study of 22 patients with combination syndrome who were treated with implants in anatomic buttresses in the atrophic maxilla was performed. The inclusion criteria were Classes IV and V Cawood and Howell maxillary atrophy, rehabilitation with implants placed in anatomic buttresses, the presence of anterior remnant teeth in the mandible, and a minimum follow-up of 12 months after implant loading. The criteria of Buser et al were used to evaluate implant success, and marginal bone loss was measured on periapical radiographs. Statistical analysis was performed to relate implant success and marginal bone loss to gender, degree of maxillary atrophy, implant technique, and prosthesis type. A total of 18 patients fulfilled the inclusion criteria. A total of 117 implants were placed; 32 were placed with the conventional technique in the alveolar ridges with enough height and width, 35 were positioned palatally, 30 were tilted in the frontomaxillary buttress, 10 were placed in the pterygomaxillary area, 6 were placed in the nasopalatine canal, and 4 were zygomatic implants. The follow-up ranged from 1 to 7 years after implant loading. Of the 117 implants, 7 failed, for an implant success rate of 94%. The mean marginal bone loss was 0.63 mm. A statistically significant relation was found between bone loss and implant placement technique and the level of maxillary atrophy, being greater in tilted implants and in Class V Cawood and Howell maxillary atrophy. Implants in anatomic buttresses allow rehabilitation of atrophic maxillae in patients with combination syndrome. The implant success rate was high, and a mean marginal bone loss of 0.63 mm was recorded.

• Microvascular reconstruction of the mouth, jaws, and face: experience of an Australian oral and maxillofacial surgery unit.

  Microvascular reconstruction of oncologic surgical and traumatic defects has been globally practiced by plastic and orthopedic surgical disciplines since the early 1970s. During the past 20 years,Microvascular reconstruction of oncologic surgical and traumatic defects has been globally practiced by plastic and orthopedic surgical disciplines since the early 1970s. During the past 20 years, reconstructive techniques have been progressively incorporated into the purview of oral and maxillofacial and otolaryngology-head and neck surgeons, particularly those practicing in Europe, the United Kingdom, and China. There has also been a steady increase in the adoption of these techniques in North America, South America, and Japan. We reviewed our experience (during a 5-year period) with microvascular reconstruction of postablative defects in the oral and maxillofacial region. To our knowledge, resection and neck dissection (or neck exploration in benign free tissue transfer); undertaken by an oral and maxillofacial surgeon), and free tissue transfer reconstruction (undertaken by otolaryngology head and neck and oral and maxillofacial surgeons) of ablative defects of the mouth, jaws, and face (managed within an Australian head and neck cancer multidisciplinary care team) have not been previously reported. The study cohort comprised 107 patients who underwent 109 microvascularly anastomosed free tissue transfers. Of the 107 patients, 79 were males and 38 were females. The median age was 62 years (range 15 to 87). The clinicodemographic analyses and the range of complications observed in this patient cohort are reported. The overall flap success rate in our study was 97%. The surgical outcomes of our study compare favorably with those previously reported.

  The aim of this study was to compare the presurgical and postsurgical electromyographic (EMG) activities of the lips in patients with skeletal Class III treated with combined orthognathic surgery andThe aim of this study was to compare the presurgical and postsurgical electromyographic (EMG) activities of the lips in patients with skeletal Class III treated with combined orthognathic surgery and contrast these data with those obtained from a control group with skeletal Class I. Ten patients with skeletal Class III underwent the registration of EMG activity before an orthognathic surgical procedure and 4 months after surgery. The results were compared with a control group of 11 healthy patients with skeletal Class I and clinical and EMG lip competence. EMG activity was recorded from the upper orbicularis oris and mentalis muscles during swallowing, lips in contact (LC), and lips apart (LA) using bipolar surface electrodes. The competence condition was assessed by determining the difference in the EMG activity of the mentalis muscle (LC-LA ≤0 for lip competence). Patients with skeletal Class III showed greater EMG activity than the control group before and after surgery. Patients with skeletal Class III showed a significantly greater difference in LC-LA than the control group before surgery for the 2 muscles (P < .05). No significant difference was found between the skeletal Class III group after surgery and the control group for the mentalis muscle (P > .05). Four months after treatment with orthognathic surgery, patients with skeletal Class III and an initial muscle activity pattern of lip incompetence different from the control group (P < .05) showed EMG values compatible with lip competence. These values were similar to the control group.

  Mucoceles are benign, slow-growing lesions defined as mucus-filled pseudocystic formations. Paranasal mucoceles predominantly affect the frontal sinus (60% to 65%), followed in frequency by theMucoceles are benign, slow-growing lesions defined as mucus-filled pseudocystic formations. Paranasal mucoceles predominantly affect the frontal sinus (60% to 65%), followed in frequency by the ethmoidal (20% to 30%), maxillary (10%), and sphenoid (2% to 3%) sinuses. Mucoceles usually arise because of sinus ostium obstruction, preceded by infection, fibrosis, inflammation, trauma, surgery or tumors such as osteomas. Mucoceles arising from the frontal sinus present with a variety of clinical signs, including decreased visual acuity, visual field abnormalities, proptosis, ptosis, periorbital swelling, displacement of the globe, restricted ocular movements, and choroidal folds. We describe a case of orbital involvement from a mucocele of the frontal sinus 30 years after the initial trauma, with a review of the published data concerning the etiology, diagnosis, and treatment planning.

When these assessments are based on the judgment of the treating doctor, there is often an inherent positive bias. As a result, there has been increased interest in using patient-based assessments. The purpose of this study was to compare doctor's and patient's assessments of the outcomes of treatment in a series of patients with various temporomandibular disorders (TMDs). MATERIALS AND METHODS: Fifty-two consecutive TMD patients were initially given a questionnaire designed to evaluate their pain, problems eating and sleeping, the occurrence of headache and earache, the presence of temporomandibular joint pain and/or jaw stiffness in the morning, and interference with daily activity. The patients then filled out the same questionnaire at each post-treatment visit, and the findings were compared with the baseline information. At each visit, the treating doctor also recorded a global evaluation of the patient's progress as excellent, good, fair, or poor. RESULTS: Comparison of the doctor's global evaluation with the patient's evaluation based on the questionnaire showed a discrepancy in 44% of the cases. When there was a discrepancy, the doctor scored the improvement better than the patient 54.5% of the time and worse than the patient 45.5% of the time. CONCLUSIONS: The results of this study confirm the unreliability of using a global opinion by the treating doctor for outcome assessment in patients with various TMDs.

• Does a Pulsed Mode Offer Advantages Over a Continuous Wave Mode for Excisional Biopsies Performed Using a Carbon Dioxide Laser?

  Authors: Valerie G A Suter, Hans Jörg Altermatt, Thomas Dietrich, Peter A Reichart, Michael M Bornstein

  Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons.

  PURPOSE: Animal studies of excisional biopsies have shown less thermal damage when a carbon dioxide (CO(2)) laser (10.6 μm) is used in a char-free (CF) mode than in a continuous-wave (CW) mode. ThePURPOSE: Animal studies of excisional biopsies have shown less thermal damage when a carbon dioxide (CO(2)) laser (10.6 μm) is used in a char-free (CF) mode than in a continuous-wave (CW) mode. The authors' aim was to evaluate and compare clinical and histopathologic findings of excisional biopsies performed with CW and CF CO(2) laser (10.6 μm) modes. MATERIALS AND METHODS: This prospective randomized controlled clinical trial included 60 patients with similar fibrous hyperplasias of the buccal plane willing to undergo excisional CO(2) laser biopsy. Patients were randomly allocated to the CW (5 W) or CF (140 Hz, 400 μs, 33 mJ) group. Duration of surgery, intra- and postoperative complications, and the width (micrometers) of the histopathologic collateral thermal damage zone were registered as primary outcome variables. Secondary outcome variables were pain (patients filled in a visual analog scale [VAS]) and analgesic intake (recorded by patients). RESULTS: The study group consisted of 36 women and 24 men with a median age of 50.5 years. Median durations of surgery were 74.5 seconds in the CW group and 83.5 seconds in the CF group. Intraoperative venous bleeding occurred in 16.7% of patients in the CW group and in 13.3% of patients in the CF group. Median areas of histopathologic collateral damage zones were similar in the CW group (166.5 μm) and the CF group (162.5 μm). There was no statistically significant difference between the VAS values of the 2 groups. Analgesic intake was recorded by 16.7% of patients in the CW group and by 6.7% of patients in the CF group (P = .23, not significant). No statistically significant correlation was found between areas of thermal damage zones and postoperative VAS scores. CONCLUSIONS: In contrast to previous animal studies, no significant difference was found in the widths of thermal damage zones between the CW and CF groups. The VAS values and analgesic intake were low in the 2 groups. The 2 CO(2) laser modes are appropriate for the excision of intraoral mucosal lesions. A safety border of at least 1 mm is recommended regardless of the laser mode used.

MATERIALS AND METHODS: The labial surfaces of 195 bovinePURPOSE: To evaluate the best method for decontaminating tooth enamel contaminated by contact with blood before bonding orthodontic buttons. MATERIALS AND METHODS: The labial surfaces of 195 bovine incisors initially received prophylaxis, followed by 37% phosphoric acid etching, adhesive application, and light polymerization. After this, the labial surfaces of all teeth were contaminated with blood. The teeth were then randomly divided into 13 groups (n = 15), comprising the control group (treated according to the manufacturer's recommendations) and 12 experimental groups treated by the following decontamination methods: group 1, no decontamination; group 2, washing with distilled water; group 3, washing with physiologic solution; group 4, jets of air; group 5, gauze; group 6, cotton wool; group 7, distilled water plus jets of air; group 8, distilled water plus gauze; group 9, distilled water plus cotton wool; group 10, physiologic solution plus jets of air; group 11, physiologic solution plus gauze; and group 12, physiologic solution plus cotton wool. RESULTS: No statistical differences were shown between the control group and groups 4, 7, 10, and 11 (P > .05). The lowest bond strength values were shown in group 1, in which no decontamination was performed, and groups 6 and 12, which were decontaminated with cotton wool and physiologic solution plus cotton wool, respectively. CONCLUSIONS: The best method of decontaminating enamel contaminated with blood is washing with physiologic solution, followed by drying with jets of air and gauze or drying with jets of air only.

MATERIALS AND METHODS: The present study was undertaken in 70 patients with symptomatic stones in the hilum of submandibular glands who underwent endoscopy-assisted sialolithectomy from December 2005 through March 2011 in the Peking University School and Hospital of Stomatology. The operative data were analyzed retrospectively. All patients were followed periodically postoperatively. Submandibular gland function was investigated by postoperative symptoms, clinical examinations, sialography, and scintigraphy. RESULTS: Submandibular stones were successfully removed in 65 patients, with a success rate of 92.9%. Temporary lingual nerve injury occurred in 1 patient. Two patients developed ranulae and underwent an uneventful sublingual gland excision. During a mean follow-up of 23 months (range, 6 to 55 mo), 52 of 65 patients were symptom free, whereas 11 patients complained of occasional swelling of the affected gland at mealtimes and 2 patients developed a recurrent stone. Thirty patients underwent postoperative sialography. The sialographic appearances included 4 types: 1) approximately normal; 2) the main duct was significantly dilated at the hilum, but no persistent contrast was seen on the functional film; 3) the main duct was significantly dilated in the hilar region, and persistent contrast was seen at the dilated hilum of the functional film; 4) the main duct was dilated or strictured, and persistent contrast was seen on the functional film. Three of the 4 patients who underwent scintigraphy exhibited good function. CONCLUSIONS: Sialoendoscopy-assisted sialolithectomy is a safe and effective gland-preservation technique for patients with hilar stones of the Wharton's duct.

  PURPOSE: To investigate the periapical tissue response of 4 different retrograde root-filling materials, ie, intermediate restorative material, thermoplasticized gutta-percha, reinforced zinc oxidePURPOSE: To investigate the periapical tissue response of 4 different retrograde root-filling materials, ie, intermediate restorative material, thermoplasticized gutta-percha, reinforced zinc oxide cement (Super-EBA), and mineral trioxide aggregate (MTA), in conjunction with an ultrasonic root-end preparation technique in an animal model. MATERIALS AND METHODS: Vital roots of the third and fourth right mandibular premolars in 6 healthy mongrel dogs were apicectomized and sealed with 1 of the materials using a standardized surgical procedure. After 120 days, the animals were sacrificed and the specimens were analyzed radiologically, histologically, and scanning electron microscopically. The Fisher exact test was performed on the 2 outcome values. RESULTS: Twenty-three sections were analyzed histologically. Evaluation showed better re-establishment of the periapical tissues and generally lower inflammatory infiltration in the sections from teeth treated with the intermediate restorative material and the MTA. New root cement on the resected dentin surfaces was seen on all sections regardless of the used material. New hard tissue formation, directly on the surface of the material, was seen only in the MTA sections. There was no statistical difference in outcome among the tested materials. CONCLUSIONS: The results from this dog model favor the intermediate restorative material and MTA as retrograde fillings when evaluating the bone defect regeneration. MTA has the most favorable periapical tissue response when comparing the biocompatibility of the materials tested.

  Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons.

  PURPOSE: The present study aimed to measure postsurgical swallowing function in patients 5 years after the surgical treatment of tongue carcinoma. PATIENTS AND METHODS: Using a retrospective cohortPURPOSE: The present study aimed to measure postsurgical swallowing function in patients 5 years after the surgical treatment of tongue carcinoma. PATIENTS AND METHODS: Using a retrospective cohort study design, the investigators enrolled postsurgical patients treated for tongue carcinomas in Hokkaido University Hospital. The primary outcome variable was oropharyngeal swallow efficiency (OPSE) determined by videofluoroscopic evaluation, and OPSE at follow-up was compared with that at discharge. Other variables included current nutritional status (body mass index, serum albumin), dietary intake, self-rating of current swallowing function, and occurrence of pneumonia. Statistical analysis used the paired t test and the Spearman rank correlation. RESULTS: Swallowing function was assessed in 20 patients (11 men and 9 women) who underwent the surgical treatment of tongue carcinomas; the median age was 70 years (range, 56 to 90 yrs). The mean OPSE values for liquid and paste at follow-up were 26.6 ± 21.2 and 21.9 ± 22.5, respectively. The mean values for the body mass index and serum albumin at presentation were 22.2 ± 3.4 kg/m(2) and 4.5 ± 0.3 g/dL, respectively. All patients had a full oral intake of foods, with a mean self-rated value of 6.4 ± 2.5, a value acceptable to the patients. Pneumonia requiring hospitalization did not occur in these patients. CONCLUSIONS: The long-term follow-up of patients after the surgical treatment of tongue carcinomas showed acceptable levels of oral function and nutritional status despite objective measurements of poor swallowing efficiency assessed using videofluoroscopy.
