RESUMEN
Botulinum toxin (BTX) injection is a common treatment for bruxism, but there is no literature on potential salivary gland complications. This paper presents a case of acute parotitis in a 60-year-old female following BTX injections to the masseter muscle. This case highlights the possible salivary gland complications after injection of BTX into the masticatory muscles. An electronic search of PubMed and Embase databases was conducted to create a literature review in order to delve into the etiology behind the presented case and suggest potential preventive measures to avoid salivary gland complications. Thirty-one articles are reviewed and discussed. Currently, there is no consensus on the causes of the mentioned complication. However, various factors have been proposed, encompassing anatomical, physiological, biological, and physical aspects. Several methods have been recommended for the safe injection of BTX, which, along with better medical training and knowledge, are warranted to achieve predictable results.

BACKGROUND: Facial feminization surgical procedures are involving several surgical disciplines in multiple surgical sites and therefore may carry the risk of developing infections. Data on the development of postsurgical infection (PSI) and contributing factors in male-to-female transgender people (transwomen) undergoing facial feminization surgery are scarce. The aim of this study was to investigate the contributing factors to develop PSIs in facial feminization surgical procedures. METHODS: Data from the medical records of 40 transwomen who underwent facial feminization surgeries in our institution between 2019 and 2021 were analyzed. The independent variables included demographic parameters (weight, body mass index, medical comorbidities and age), details of the surgical procedure (type, duration and whether another procedure had been performed concomitantly), type, dosage and route of administration of postoperative antibiotics and steroids, length of hospitalization and follow-up duration. Postsurgical infection was designated a dependent variable. RESULTS: Five out of 40 patients (12.5%) developed PSI. The surgery of those with PSIs involved more sites, and the duration of nasal tamponade was more than four times longer than for patients who did not develop a PSI. CONCLUSIONS: The current study revealed higher postsurgical infections rates after lengthy surgeries or when it involves several surgical facial feminization procedures. Multicenter clinical trial on a big cohort may enable better evidence-based results. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Background and objectives: This retrospective cohort study aimed to compare three postoperative antibiotic protocols of different durations on surgical-site-infection (SSI) rates following orthognathic surgery for the correction of jaw deformities. Materials and methods: An analysis on data collected from the medical files of 209 patients who underwent orthognathic surgery between 2010 and 2019 was conducted. The patients were divided into three groups according to the postoperative antibiotic protocol-Group 1 (24 h), Group 2 (2-3 days), and Group 3 (>3 days). Dependent and independent variables were collected, analyzed, and compared between the three groups. Results: Group 1 included 30 patients (14.3%), Group 2 included 123 patients (58.9%), and Group 3 included 56 patients (26.8%). The vast majority of the postoperative antibiotics were amoxicillinand clavulanic acid (87.1%). The duration of the surgery and the use of a feeding tube were significantly different between Groups 1 and 3 (p < 0.001 and p = 0.005, respectively). There was no significant difference in SSI rates between the three groups (p = 0.642). The use of antibiotics beyond the immediate postoperative period provides no increased benefit regarding infection prevention. Conclusions: In young and healthy patients undergoing orthognathic surgery, a 24hregimen of postoperative antibiotics may be sufficient.

Background and Objective: Hyposalivation and xerostomia can result from a variety of conditions. Diagnosis is based on a combination of medical history, clinical and serological parameters, imaging, and minor salivary gland biopsy when indicated. The Objective was to characterize microscopic changes in minor salivary gland biopsies taken in patients with xerostomia. Materials and Methods: 10-year retrospective analysis of minor salivary gland biopsies, 2007-2017. Histomorphometric analysis included gland architecture, fibrosis, fat replacement, inflammation and stains for IgG/IgG4, when relevant. Results: 64 consecutive biopsies, of which 54 had sufficient tissue for diagnosis of Sjogren's Syndrome (SS) were included (18 males, 46 females, average age 56 (±12.5) years). Only 12 (22.2%) were microscopically consistent with SS, none stained for IgG4. Medical conditions were recorded in 40 (63%), most frequently hypertension and hyperlipidemia (28% each). Medications were used by 45 (70%), of which in 50% more than one. Xerostomia in non-SS cases was supported by abnormal gland morphology, including acinar atrophy, fibrosis and fatty replacement. All morphological abnormalities are correlated with age, while fatty replacement correlated with abnormal lipid metabolism. Multiple medications correlated with microscopic features which did not correspond with SS. Conclusions: SS was confirmed in a minority of cases, while in the majority fatty replacement, fibrosis and multiple medications can explain xerostomia, and are related to aging and medical conditions. Medical history and auxiliary tests could lead to correct diagnosis in non-SS patients, avoiding biopsy. The necessity of a diagnostic biopsy should be given serious consideration only after all other diagnostic modalities have been employed.

Background and Objectives: Peri-implantitis is a common finding among patients with dental implants. There is no consensus regarding the treatment of this disease, but in many cases, surgical treatment is common practice. A histopathological analysis is not an integral part of suggested protocols. The present study investigated the clinical and histopathological parameters of lesions mimicking peri-implantitis and correlated them with the outcome and follow-up data. Materials and Methods: The study included 65 consecutive biopsies taken from peri-implantitis patients between 2008-2019. Results: The three common diagnoses were fibro-epithelial hyperplasia 20 (30.7%), pyogenic granuloma 16 (24.6%), and peripheral giant cell granuloma 15 (23%). There were 18 cases of recurrent lesions in the study group (27.7%). The recurrence rate was the highest in peripheral giant cell granuloma (8, 12.3%), versus 6% in pyogenic granuloma and fibro-epithelial hyperplasia. These differences in the recurrence rate were statistically significant (p = 0.014). Conclusions: This study emphasizes the necessity of submitting tissue of peri-implantitis cases for histopathological analysis since the more locally aggressive lesions (peripheral giant cell granuloma and pyogenic granuloma), which comprise nearly half of the cases in this study, do not differ in clinical or radiographic characteristics from other peri-implant lesions.

PURPOSE: Odontogenic sinusitis (OS) can be caused by infectious conditions of the posterior maxillary teeth. The maxillary sinus has been most often involved because of its proximity to the posterior maxillary teeth. Often the anterior ethmoids and frontal sinuses will be involved by the infective process. The underlying odontogenic condition must be addressed before or during sinus surgery. The role of frontal sinusotomy in the treatment of these patients has been poorly described. Our objective was to present the surgical outcomes of patients with OS involving the frontal sinus who had undergone middle meatal antrostomy alone. PATIENTS AND METHODS: A prospective analysis of all patients who had undergone surgery at a single tertiary center to treat OS involving the frontal sinus from November 2015 to December 2018 was performed. Their preoperative assessment findings, surgical findings, and postoperative outcomes were analyzed. RESULTS: A total of 45 patients (23 men and 22 women), with a median age of 57 years (range, 20 to 83 years), were enrolled in the present study. All anterior sinuses (frontal, anterior ethmoids, and maxillary sinuses) were clinically and radiographically involved in all the patients. Each patient underwent endoscopic wide maxillary middle meatal antrostomy concurrent with dental intervention. The average follow-up was 7 months. No signs of active frontal disease were detected by postoperative endoscopy in any patient, and no patient required revision surgery. CONCLUSIONS: The results from the present study have shown that no justification exists for frontal sinusotomy for the treatment of OS involving the frontal sinus. Frontal sinusitis is a secondary infectious and inflammatory process that will resolve once the underlying odontogenic condition has healed and wide middle meatal antrostomy has been performed.

PURPOSE: We sought to study the spectrum of oral pathologies presenting clinically with papillary-verrucous features. MATERIALS AND METHODS: A 10-year (2007 to 2016) retrospective study of oral papillary lesions was undertaken. All biopsy reports that included a clinical description of papillary or verrucous architecture were retrieved. The data collected included clinical features, size, color, location, histopathologic diagnosis, age, and gender. RESULTS: The study included 137 patients, with a total of 150 lesions. The ages ranged from 10 weeks to 84 years (mean, 49 years). Histopathologically, 60% of cases were human papillomavirus (HPV) related, 19% showed hyperplasia, 11% had hyperplastic candidiasis, 7% were dysplastic or malignant, and 3% were benign of unknown etiology. Among the 7% of lesions diagnosed with dysplasia or malignancy, only 60% were suspected to have malignancy at the time of biopsy. HPV-related lesions and hyperplasia were most frequently found on the tongue (38% and 41%, respectively) and soft palate (21% and 14%, respectively). Hyperplastic candidiasis was most frequently found on the buccal mucosa and tongue (35% and 24%, respectively). Squamous cell carcinoma was found in 1.3% of total lesions and verrucous carcinoma in 1.3%. Of the verrucous or papillary malignant lesions, 50% were found on the gingiva. Most malignant lesions occurred in the 40- to 60-year age group. CONCLUSIONS: The results of this study suggest that, because of the wide spectrum of entities presenting clinically with a papillary-verrucous architecture, biopsy is necessary for diagnosis. The clinical presentation allowed for overall accurate diagnosis in only 47% of cases and 60% accuracy in dysplastic or malignant cases. It is of considerable importance to correctly identify those lesions that are HPV related but at the same time to rule out those lesions that are unrelated to HPV to help alleviate a patient's anxiety. Most important, biopsy is mandatory for the recognition of malignant lesions with a papillary-verrucous architecture, which may mimic other benign entities in the group of papillary-verrucous lesions.

OBJECTIVE/HYPOTHESIS: Inflammatory conditions of the posterior maxillary teeth may cause odontogenic sinusitis (OS), which most commonly involves the maxillary sinus due to its proximity to those teeth. The infective process frequently spreads outside the maxillary sinus, involving the anterior ethmoid and the frontal sinuses. The underlying odontogenic condition must be addressed before or during the surgical procedure. The role of frontal sinusotomy in this setting has not been studied. The aim of this study is to present the surgical outcome of patients who presented with OS involving the frontal sinus and were managed by middle meatal antrostomy alone. STUDY DESIGN: Prospective cohort study. METHODS: All patients operated in our department due to OS involving the frontal sinus from November 2015 to December 2017 were recruited. Their demographics, complaints, imaging and endoscopic findings, surgical features and outcome were analyzed. RESULTS: Twenty-five patients (male-to-female ratio 9:16) with a median age of 49 years (IQR = 43-53) were enrolled. The maxillary, frontal and anterior ethmoid sinuses were involved in each case, and each patient underwent maxillary middle meatal antrostomy alone. The median follow-up was 10 months, and no signs of active frontal disease were detected by postoperative endoscopy in any patient. CONCLUSION: Frontal sinusotomy is apparently not necessary to resolve OS involving the frontal sinus. The frontal sinusitis may reflect a reactive process that regresses spontaneously once the underlying odontogenic condition is addressed and a middle meatal antrostomy had been performed. LEVEL OF EVIDENCE: 2B.

There are numerous surgical approaches for oro-antral-fistula (OAF) closure. Secondary sinus disease is still considered by many experts a relative contra indication for primary closure. To describe a single-stage combined endoscopic sinus surgery and per-oral buccal fat pad (BFP) flap approach for large OAF causing chronic maxillary sinusitis. The records of all the patients with OAF and chronic manifestations of secondary rhinosinusitis that were treated between 2010 and 2013 in our tertiary care medical center were reviewed. The exclusion criteria were: OAF ≤ 5 mm, resolved sino-nasal disease, OAF secondary to malignancy, recurrent fistula, medical history that included radiotherapy to the maxillary bone and age <18 years. Each procedure was performed by a team consisting of a rhinologist and a maxillofacial surgeon. The surgical approach included an endoscopic middle antrostomy with maxillary sinus drainage, and a per-oral BFP regional flap for OAF closure. Total OAF closure, complications and need for revision surgeries. Forty-five patients that underwent OAF closure together with sinus surgery using a combined endoscopic sinus surgery (ESS) and BFP flap approach met the inclusion criteria. There were 28 males and 17 females with a mean ± SD age of 53.5 ± 14.9 years (range 22-80 years). The presenting signs and symptoms included purulent rhinorrhea (n = 22, 48.9 %), foreign body in sinus (n = 10, 22.2 %) nasal congestion (n = 7, 15.5 %), halitosis (n = 6, 13.3 %) and pain (n = 5, 12.2 %). Surgical complications included local pain (n = 2, 4.4 %), persistent rhinitis (n = 2, 4.4 %) and synechia (n = 1, 2.2 %). One patient required revision surgery due to an unresolved OAF. The OAF of all the other 44 patients (97.8 %) was closed after the first procedure and the paranasal sinuses on the treated side were completely recovered. The mean follow-up time for the group was 7.6 ± 4.3 months (7-21 months), and no untoward sequelae or recurrence were reported. Combined, one step, endoscopic Maxillary sinus drainage together with per-oral BFP flap approach is an efficacious surgical approach for safe closure of OAFs that are complicated with secondary chronic maxillary sinusitis.

OBJECTIVES: To report our experience with combined one-stage double-team maxillary sinus floor elevation (SFE) and endonasal endoscopic sinus surgery (ESS) procedure for concomitant inflammatory sinonasal pathologies. MATERIAL AND METHODS: Clinical records of all patients that underwent maxillary SFE in conjunction with endonasal ESS for the treatment of inflammatory sinonasal pathologies between 2011 and 2013 were retrospectively reviewed. All included patients had a sinonasal-related pathology that was first suggested by the referring physician and was later confirmed clinically and radiographically by our combined team comprised of otorhinolaryngologist and maxillofacial surgeons. RESULTS: Fifteen combined SFE+ESS surgeries were performed using either xenograft-allograft mixture or autograft-xenograft-allograft mixture. The study group included seven males and eight females, whose median age was 55 years (range, 45-78 years). Seven patients underwent a unilateral SFE, and eight patients underwent bilateral SFEs. During the same session, four patients also underwent septoplasty for deviated nasal septum, five patients underwent bilateral maxillary antrostomy, 10 patients underwent unilateral maxillary antrostomy, and six patients underwent maxillary sinus cyst resection. Seven combined procedures were performed under active infection. There were no intra-operative complications, and all SFE+ESS combined procedures were successful. Three patients required extended postoperative antibiotic treatment for persistent sinusitis. One patient reported infraorbital hypoesthesia. CONCLUSIONS: We first report the promising outcomes of the double-team one-stage SFE+ESS procedure performed by a combined team of otorhinolaryngologist and maxillofacial surgeons, including on patients presenting with an infection of the sinuses at the time of surgery.

PURPOSE: The challenge of oromandibular reconstruction (OMR) after oncologic resections has been repeatedly addressed in the literature. Although final oncologic margins can be decided only during surgery, various attempts have been made to create an ideal and accurate platform for OMR. The purpose of this article is to present the V-stand, a versatile surgical platform for OMR using a 3-dimensional (3D) virtual modeling system. MATERIALS AND METHODS: Seventeen patients requiring an OMR were included in the study. A presurgical computed tomogram was obtained and virtual resection and reconstruction with a free fibular flap were planned using 3D virtual surgery software. The mandible was reconstructed intraoperatively using the V-stand, which served as a template for the lower border of the mandible and the lateral aspects of the stand were fixed to the proximal mandibular segments using 2-mm titanium screws. RESULTS: Patients' average age was 53 years (5 to 72 yr). Median follow-up was 19 months (2 to 35 months). All reconstructed mandibles resulted in good function and esthetics. CONCLUSIONS: The V-stand offers a safe and time-efficient method for OMR. It provides an excellent means for accurate spatial positioning of a fibular free flap. The V-stand preserves the original dimensions of the reconstructed mandible and can overcome surgical ablation modifications because it is not dependent on the precision of the resection, but rather provides a mold for the entire mandible.

BACKGROUND: Feminization laryngochondroplasty (FLC) methods have evolved from using a midcervical incision to a submental, less visible incision. The scar may be unacceptable to the patient because it signals gender reassignment surgery. An endoscopic transoral approach to FLC inspired by transoral endoscopic thyroidectomy was recently suggested to avoid the neck scar; however, it requires special equipment and has a long learning curve. A vestibular incision is used to approach the chin in lower-third facial feminization surgery. The authors propose that this incision may be extended to the thyroid cartilage in performing direct FLCs. The authors describe their experience with a novel, minimally invasive, direct transvestibular use of the chin-reshaping incision. METHODS: The medical records of all patients who underwent direct transvestibular FLC (DTV-FLC) from December of 2019 to September of 2021 were retrieved and reviewed for this retrospective cohort study. Data on the operative, postoperative, and follow-up courses, complications, and functional and cosmetic results were retrieved. RESULTS: Nine transgender women were included. Seven DTV-FLCs were performed during lower-third facial feminization surgery, and two were isolated DTV-FLCs. One was a revision DTV-FLC. Transient minor complications were encountered and resolved by the postoperative visit at 1 to 2 months. Vocal fold function and voice quality remained intact. Eight available patients were satisfied with the surgical results. A blinded assessment by eight plastic surgeons determined that seven procedures were successful. CONCLUSION: The novel DTV-FTLC approach either in isolation or as part of lower-third facial feminization surgery facilitated scar-free FLC with satisfactory cosmetic and functional results. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

PURPOSE: Cancer is the second leading cause of death globally. However, by implementing evidence-based prevention strategies, 30%-50% of cancers can be detected early with improved outcomes. At the integrated cancer prevention center (ICPC), we aimed to increase early detection by screening for multiple cancers during one visit. METHODS: Self-referred asymptomatic individuals, age 20-80 years, were included prospectively. Clinical, laboratory, and epidemiological data were obtained by multiple specialists, and further testing was obtained based on symptoms, family history, individual risk factors, and abnormalities identified during the visit. Follow-up recommendations and diagnoses were given as appropriate. RESULTS: Between January 1, 2006, and December 31, 2019, 8,618 men and 8,486 women, average age 47.11 ± 11.71 years, were screened. Of 259 cancers detected through the ICPC, 49 (19.8%) were stage 0, 113 (45.6%) stage I, 30 (12.1%) stage II, 25 (10.1%) stage III, and 31(12.5%) stage IV. Seventeen cancers were missed, six of which were within the scope of the ICPC. Compared with the Israeli registry, at the ICPC, less cancers were diagnosed at a metastatic stage for breast (none v 3.7%), lung (6.7% v 11.4%), colon (20.0% v 46.2%), prostate (5.6% v 10.5%), and cervical/uterine (none v 8.5%) cancers. When compared with the average stage of detection in the United States, detection was earlier for breast, lung, prostate, and female reproductive cancers. Patient satisfaction rate was 8.35 ± 1.85 (scale 1-10). CONCLUSION: We present a proof of concept study for a one-stop-shop approach to cancer screening in a multidisciplinary outpatient clinic. We successfully detected cancers at an early stage, which has the potential to reduce morbidity and mortality as well as offer substantial cost savings.[Media: see text].

Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory condition of unknown etiology. Although the salivary glands are currently considered among the most commonly affected among them, oral and maxillofacial surgeons are generally not familiar with the condition. Enlargement of the major salivary glands may be the first identifiable sign of IgG4-RD. A salivary gland biopsy along with IgG4 serum level assessment may help differentiate IgG4-related sialadenitis (IgG4-RS) from malignancies, infectious diseases, and obstructive conditions. Greater knowledge and higher levels of awareness of IgG4-RS may contribute to the expansion of differential diagnostic and treatment approaches. This case report describes a patient with bilateral submandibular salivary gland swelling who was diagnosed as having IgG4-RS on the basis of the histopathologic findings of a submandibular salivary gland biopsy and subsequent IgG4 levels.

The purpose of this study is to evaluate mandibular osteotomy procedures during orthognathic surgery, with an emphasis on the complications of the two leading procedures: intraoral vertical ramus osteotomy (IVRO) and sagittal split osteotomy (SSO). We conducted a retrospective cohort study by extracting the records of patients who underwent either IVRO or SSO procedures during orthognathic surgery in a single center between January 2010 and December 2019. A total of 144 patients were included (median age of 20.5 years, 52 males). The IVRO:SSO ratio was 118:26 procedures. When referring to all surgeries performed, IVRO procedures were associated with shorter hospitalization than the SSO procedures, while the overall durations of surgery and follow-up periods were comparable. In contrast, when referring only to bimaxillary procedures, the duration of the IVRO bimaxillary procedures was significantly shorter than the SSO bimaxillary procedures. There were 53 complications altogether. Postoperative complications consisting of skeletal relapse, temporomandibular joint dysfunction, sensory impairment, and surgical-site infection were significantly fewer in the IVRO group. Both types of osteotomies have acceptable rates of complications. IVRO appears to be a safer, simpler, though less acceptable procedure in terms of patient compliance.

OBJECTIVES: The purpose of our study is to retrospectively analyze and compare the patterns of maxillofacial-related injuries among rides of electric-powered bikes (E-bikes) and electric-powered scooters (E-scooters), the associated risk factors, and the required treatment. MATERIALS AND METHODS: The medical files of all riders presenting to the emergency department at the Tel Aviv Sourasky Medical Center between 2019 and 2020 with oral- and maxillofacial-related injuries due to E-bike and E-scooter accidents were reviewed. RESULTS: A total of 320 riders sustained oral- and maxillofacial-related injuries due to trauma involving E-bikes and E-scooters during the study period. E-scooter riders were involved in 238 accidents (74.5%) while E-bike riders accounted for the remaining 82 accidents (27.5%). Eighty-four out of 320 riders (26.25%) were hospitalized and required surgical interventions. Most of the 232 riders (72.5%) who reported not wearing a protective helmet during the index accident were E-scooter riders. In addition, 39 riders (18.66%) were riding either of these electric-powered vehicles under the influence of alcohol. CONCLUSIONS: E-bike riders are more likely to sustain a maxillofacial fracture than E-scooter riders. Not wearing a protective helmet and riding under the influence of alcohol are major risk factors for maxillofacial injuries.

OBJECTIVE: Submandibular gland (SMG) malignancies are exceedingly rare. Lymph node metastasis is one of the most important determinants of outcome in SMG malignancies. The aim of this study was to investigate the overall rate of occult neck nodal metastasis in SMG malignancies. STUDY DESIGN: The study design is a meta-analysis of all studies on patients with a primary SMG malignancy, without evidence of neck nodal metastasis, who underwent an elective neck dissection (END). The search strategy identified 158 papers that appeared in print from January 1980 to July 2020. All eligible patients from the Tel-Aviv Medical Center were analyzed and consolidated into a case series. A total of 12 retrospective studies that included 306 suitable patients met inclusion criteria. RESULTS: The risk for occult metastasis in primary SMG malignancies was 0.0% to 50.0%, with a fixed effect model of 19.52% (95% CI, 14.9%-24.5%). The analyzed studies included a wide range of pathologies. The most common malignancies were adenoid cystic carcinoma and mucoepidermoid carcinoma. CONCLUSIONS: The overall rate of occult neck metastasis in SMG malignancies is relatively high, and an END should be the default intervention in these cases. An END is unwarranted in tumors judged clinically to be low stage and low grade.

The retrospective cohort study aimed to assess the incidence and characteristics of these complications in patients who underwent orthognathic procedures. Data on the intraoperative and the postoperative complications were extracted from the patients' medical files. Procedures were further subdivided into single-jaw procedures and bimaxillary procedures. A total of 209 orthognathic procedures were carried out in 190 patients. 184 (88%) were performed to treat angle class III malocclusion, while 25 (12%) aimed to treat class II malocclusion. A total of 94 complication events were observed (44.9% of 209 procedures). 22 of them occurred in single-jaw procedures (28.2% of 78 single jaw operations), and 72 occurred in bimaxillary procedures (55% of 131 bimaxillary operations). When compared regarding the type of complication, complication rates were comparable between the study groups with the exception of late-stage malocclusion. A significant difference (p-value = 0.028) in malocclusion incidences between the bimaxillary and single-jaw groups were observed (9 events, 4.3% and zero events, 0%, respectively). The majority of the complications during and following orthognathic surgical procedures are temporary or minor and require little or no treatment at all.

OBJECTIVES: Zygomatic complex (ZMC) fractures comprise up to 40% of all facial fractures. Misaligned bone fragments and misplaced fixation hardware traditionally detected postoperatively on plain radiographs of the skull might require re-operation. The intraoperative O-Arm (Medtronic, USA) is a three-dimensional (3D) computed tomographic imaging system. MATERIALS AND METHODS: This retrospective single-center study evaluated the utility of O-Arm scanning during corrective surgeries for ZMC and zygomatic arch (ZA) fractures from 2018 to 2020. Three females and 16 males (mean age, 31.52 years; range, 22-48 years) were included. Fracture instability (n=6) and facial deformity (n=15) were the most frequent indications for intraoperative 3D O-Arm scan. RESULTS: The images demonstrated that all fracture lines were properly reduced and fixed. Another scan performed at the end of the fixation or reduction stage, however, revealed suboptimal results in five of the 19 cases, and further reduction and fixation of the fracture lines were required. CONCLUSION: Implementation of an intraoperative O-Arm system in ZMC and ZA fracture surgeries assists in obtaining predictable and accurate results and obviates the need for revision surgeries. The device should be considered for precise operations such as ZMC fracture repairs.
RESUMEN
PURPOSE: The purpose of this randomized controlled trial was to compare the surgical site infection rate with short (24 hours) vs extended (7 days) antibiotic prophylaxis for maxillary sinus floor augmentation surgery. MATERIALS AND METHODS: Eighty-five patients who were candidates for unilateral or bilateral maxillary sinus floor augmentation surgery were randomly assigned to short or extended antibiotic prophylaxis. Patients were evaluated on days 7, 14, 30, 60, and 180 after surgery for symptoms and signs of infection. The primary study endpoint was the development of surgical site infection up to day 180 postoperatively. RESULTS: Patients underwent a total of 117 maxillary sinus floor augmentation surgeries, 62 in the short prophylaxis arm and 55 in the extended prophylaxis arm. Fifty-three patients (62%) had unilateral surgery, and 32 (38%) had bilateral surgery. Three patients developed a surgical site infection by 180 days postsurgery (overall rate, 2.6%): one patient (1.6%) in the 24-hour arm and two (3.6%) in the extended prophylaxis arm. All three patients received antibiotic treatment, and the infections resolved entirely. CONCLUSION: A low rate of surgical site infection was observed after maxillary sinus floor augmentation, and there was no apparent advantage to extended (7 days) vs short (24 hours) duration of antibiotic prophylaxis. The findings do not support the use of extended postprocedural chemoprophylaxis for patients undergoing maxillary sinus floor augmentation.
