Watching Food Videos Leads to Postparotidectomy Salivary Fistula.

Salivary fistula is a common postparotidectomy complication, and eating sour or spicy food ranks among the leading causes. Here we report a rare postparotidectomy salivary fistula case, a 31-year-old female patient who affirmed that she did not eat any irritating foods but admitted that she had been watching food videos for up to 4 hours every day since she left hospital. This case offers a cautionary tale about postparotidectomy precautions.

Iodoform Gauze Packing is an Alternative Therapy for Postoperative Parotid Fistula.

Surgery-related salivary fistula is the result of intraoperative or postoperative parotid gland damage and extravasation of fluid secreted by acinar into the interstitial space. Most are treated conservatively. Local injection of botulinum toxin is an effective method, but it is relatively expensive and not available in some hospitals. In clinical practice, the authors observed that packing iodoform gauze from the fistula toward the parotid gland can quickly stop postoperative salivary fistula in several patients. This method is simple and easy to implement, and the effect is quick. The disappearance of the salivary fistula was observed on the next day after packing the iodoform gauze. Iodoform gauze packing is an alternative therapy for postoperative parotid fistula. It can be used in areas where botulinum toxin is not available.

Management of a salivary fistula following removal of mandibular distractors in a neonate.

There are multiple management options for treatment of iatrogenic salivary fistulas including reduced oral intake, pressure dressings, total parotidectomy, tympanic neurectomy, surgical repair, radiation therapy, and pharmacotherapy. However, the optimal management of salivary fistulas is unclear due to uncertain efficacy and adverse outcomes. We present a case of a neonate that developed a submandibular fistula following removal of mandibular distractors and was ultimately successfully managed using intralesional botulinum toxin injection. The purpose of this communication is to summarize the management of this complication in the context of the current literature.

Superficial Parotidectomy: Impact of Postoperative Drainage.

BACKGROUND: Use of suction drain after superficial parotidectomy (SP) is based on national consensus considered best practice, but there is no evidence on the effect of the treatment. The aim of the present study is to evaluate the effectiveness of drainage after SP by evaluating the rate of complications after SP in relation to the (ie, duration) of drainage and tumor size. METHODS: Retrospective analysis was performed involving data from all consecutive patients undergoing SP at the Ear, Nose, and Throat department, Regional Hospital West Jutland, Denmark, between January 1, 2011, and December 31, 2017. Demographics including comorbidity, medication, tumor size, postoperative secretion through the drainage, as well as complications (hematoma, seroma, infection, fistulas, Frey syndrome, facial nerve palsy) were registered. Patients with secretion below 25 mL were compared to patients with secretion above 25 mL, that is, drainage less than 24 hours versus longer than 24 hours. Results: Two hundred five consecutive patients undergoing SP were enrolled. The overall risk of postoperative infection was 16.2%. Ten of 33 patients with infection were also diagnosed with an hematoma or seroma. The risk of infection increased with secretion above 25 mL (27.2%) compared to patients with less than 25 mL (13.1%; P = .0318). The same accounts for the risk of seromas/hematomas (P = .0055). We found no evidence that demographics or comorbidity correlated to the secretion in the drainage, but there is a tendency toward male gender having a higher risk off secretion above 25 mL (odds ratio 1.39). CONCLUSION: Overall, the risk of complications after SP increased with secretion beyond 25 mL (ie, drainage for more than 24 hours). This applied in particular to infections and seromas/hematomas demanding treatment. The use of routine drainage after SP is questionable, and a randomized trial is warranted to unravel the necessity of postoperative drainage.

[Injection of incobotulinum toxin A for the prevention of postoperative salivary fistula and sialocele]. / Primenenie botulotoksina tipa A v profilaktike posleoperatsionnykh slyunnykh svishchei i sialotsele.

The aim of the clinical study was to improve prevention of postoperative sialocele and fistulas of parotid glands. MATERIALS AND METHODS: The study included 100 patients with tumors of parotid glands treated by superficial parotidecthomy. Fifty patients received incobotulinum toxin A preoperatively, while control group consisted of 50 patients without preoperative injections. RESULTS: Salivary fistulas formed in 17% of cases in control group. Discharging of saliva through the postoperative wound for 6 days after surgical treatment were noticed in the control group in 30% of cases. There were no complications such as forming of salivary fistula and sialocele and no saliva flow from the postoperative wound on the 4th day after surgical treatment in the main group. Conclusion. The use of botulinum toxin type A proved an efficient and effective way for prevention of postoperative salivary fistulas and sialocele.

Management of postreconstructive head and neck salivary fistulae: A review of current practices.

BACKGROUND: Salivary fistulas are common complications after reconstructive head and neck surgery with significant morbidity. Yet, there are no established guidelines for their management. METHOD: A comprehensive search of PubMed was performed from 01/01/2000 to 06/31/2019 to evaluate all treatment options in postreconstructive head and neck fistulas. RESULTS: Nineteen articles with 132 patients were included. Thirty-nine of 132(30%) patients were treated with conventional wound care. All fistulas closed after 51.6±54.0 days with no refistulations. Thirty-eight of 132(29%) patients were treated with negative pressure wound therapy (NPWT). Thirty-eight of 40(95%) fistula closed after 14.7±12.0 days with no refistulations. The reduced healing time was statistically significant as compared to patients on conventional wound care (p < 0.001). Fifty-three of 132(40%) patients received surgical management. Forty-four of 53(83%) patients had complete fistula closure without postoperative complications. A pedicled flap was used in 60% of cases (n = 32). CONCLUSION: Most salivary fistulas close with conservative management. NPWT potentially shortens fistula healing time while it achieves similar closure rates as conventional wound care. In the absence of contraindications, NPWT should be trialed on all salivary fistulas. Surgical management should be reserved for large, chronic, high-risk fistulas or those not responding to a trial of conservative treatment. Secondary reconstruction should be kept as simple as possible.

Minor Parotidectomy Complications: A Systematic Review.

OBJECTIVES: To report descriptive statistics for minor parotidectomy complications. METHODS: A systematic review was performed, selecting 235 studies for analysis. The incidence of complications was tabulated, and descriptive statistics calculated. Outlier studies, 1 standard deviation above the mean, were reexamined to determine potential causal factors for each complication. All studies were examined for statistically significant differences for any potential causal factor. RESULTS: The pooled incidence of minor complications reported were hematoma 2.9% (95% confidence interval [CI]: 2.4-3.5), wound infection 2.3% (95% CI: 1.8-2.9), sialocele 4.5% (95% CI: 3.5-5.7), salivary fistula 3.1% (95% CI: 2.6-3.7), flap necrosis 1.7% (95% CI: 1.1-2.5), scar issues 3.6% (95% CI: 2.4-5.4), numbness 33.9% (95% CI: 25.6-43.4), and deformity 11.8 (95% CI: 6.9-19.5). Implants result in more wound complications, such as hematoma, sialocele, or salivary fistula. Sialocele and salivary fistula appear more frequently after less extensive parotid surgery, whereas hematoma, wound infections, flap necrosis, and aesthetic considerations are worse with more extensive resections. CONCLUSIONS: Minor parotidectomy complications are more frequent than generally assumed and related to certain factors that should be investigated. Laryngoscope, 131:571-579, 2021.

Outpatient Parotidectomy: A Retrospective Series.

OBJECTIVES: Recent literature suggests that outpatient head and neck surgery is safe and may decrease costs. This study assesses whether outpatient parotidectomy differs in complication type and rate from inpatient surgery. METHODS: Patients who underwent parotidectomy at our institution from 2011 to 2019 were retrospectively reviewed and divided by inpatient or outpatient status. Complications including infection, seroma, salivary fistula, hematoma, and flap necrosis, as well as readmission rates were tabulated. Drain placement, related to tumor size, was also analyzed using a receiver operating curve. RESULTS: 144 patients had available data for analysis. Nine of the 144 patients had complications. Seven of 98 outpatients and two of 46 inpatients had complications. There was no statistically significant difference in complication rate between the two groups (P = .518). Tumor size ≥4.62 cm3 was associated with drain placement (P = .044). CONCLUSION: Outpatient parotidectomy is a safe and viable alternative for carefully selected patients.

Drain fluid amylase as a predictor of postoperative salivary fistula in cases with benign parotid tumours.

BACKGROUND: Late diagnosis of a salivary fistula increases the risk of wound infection and scarring. The purpose of the present study was to identify a quantitative predictor of postoperative salivary fistula for cases treated with surgery. METHODS: Demographic, intraoperative and postoperative parameters for 57 cases that received surgery for benign parotid tumours were recorded from June 2017 to June 2018, of which 18 cases developed salivary fistulas. These data were analysed using univariate and binary logistic regression analyses as well as receiver operating curve analysis. RESULTS: Drain fluid amylase concentration was positively correlated with salivary fistula development (p <  0.001), with an odds ratio of 1.14 for a 1 KU/L increase in concentration and an optimal receiver operating curve cut-off value of 51,100 U/L for predicting salivary fistula development. Cases wherein the parotid-masseteric fascia remained intact were associated with a lower risk of salivary fistula development (p = 0.006). CONCLUSION: Drain fluid amylase concentration may be a valuable predictor of postoperative salivary fistula in cases with benign parotid tumours.

2-Octyl cyanoacrylate to prevent salivary fistula formation following oral cavity microvascular reconstruction: A prospective trial.

BACKGROUND: Salivary fistulas remain a significant problem in patients undergoing major head and neck reconstructive surgery. Surgical sealants have become increasingly used in cutaneous and non-cutaneous wound closure, providing a barrier to fluids/gases and promoting healing. The purpose of this study was to determine the efficacy of a common surgical sealant, 2-Octyl Cyanoacrylate (2-OCA, Dermabond®), in the prevention of salivary fistulas following free flap reconstruction of the oral cavity. METHODS: In this non-randomized, single arm prospective trial, patients undergoing free flap reconstruction of gravity-dependent oral cavity defects were recruited. Application of 2-OCA was performed along flap inset suture lines at the time of surgery. Prospectively collected trial data were propensity score matched to a control cohort to compare outcomes. Data collected include demographics, medical co-morbidities, previous treatments, primary tumor site, and subsites reconstructed. The primary outcome measure was rate of salivary fistula formation. Secondary outcomes were time to development of leak and percentage of patients tolerating oral feeding at one month post-operatively. RESULTS: In the 46 propensity score matched pairs, eight (17.4%) out of 46 patients in the 2-OCA prospective cohort and seven (15.2%) out of 46 patients in the control cohort developed postoperative salivary fistulas within the one-month study interval (p = 1.00). The average time to postoperative leak in the 2-OCA group was 12.5 days versus 7.1 days in the control cohort (p = 0.10). In the 2-OCA group, 30 (65.2%) patients were tolerating regular diet at one month post-operatively compared to 33 (71.7%) in the control cohort (p = 0.65). CONCLUSION: Salivary fistula rates after application of a 2-OCA surgical sealant were not improved compared to a control cohort in this single institutional trial. There are several surgical sealants available, each with varying elasticity and adhesiveness. Future studies are needed to identify surgical sealants that are able to provide sufficient strength and adhesion to seal closures and combat corrosive saliva, but elastic enough to handle motion related tension during swallowing and post-operative movements in the head and neck.

Sialendoscopy-Assisted Treatment of Stensen's Duct Injury: A Case Series.

PURPOSE: To evaluate the clinical value of sialendoscopy in the treatment of Stensen's duct injury. PATIENTS AND METHODS: A total of 5 patients with Stensen's duct injuries who had been treated from December 2017 to April 2019 were included in the present study. The operations were performed with the help of a sialendoscope. All patients were followed for 6 months. RESULTS: The distal end of the ductal system was found precisely with the use of the sialendoscope, and the proximal end was identified by the location of the distal end. The end-to-end anastomosis was performed successfully. None of the patients complained of salivary gland fistula at the 6-month follow-up examination. CONCLUSIONS: The stumps of the ductal system could be precisely and effectively located with the help of a sialendoscope.

Botulinum toxin for ductal stenosis and fistulas of the main salivary glands.

This study was performed to present the authors' experience with botulinum toxin therapy for salivary stenosis and salivary fistula in terms of the procedure, dosage, effectiveness, and complications. A retrospective study of all patients treated in the maxillofacial surgery department for salivary stenosis or fistula from January 2014 to September 2018 was performed. Intraglandular injections of incobotulinumtoxinA (Xeomin) were utilized. The frequency of relapse and the pain recorded before injection and at 3 months after each injection or fistula resolution were assessed. Swallowing dysfunction or any diffusion of toxin into the facial muscles was recorded. This study included 22 patients (mean age 53 years). Botulinum therapy was indicated for parotid duct stenosis in 14 patients, submandibular duct stenosis in four patients, and parotid fistula in four patients. The frequency of relapse (P = 0.0001) and pain level (P = 0.0001) decreased after botulinum therapy. The average duration of the botulinum effect was 4.50±2.00 months after the first injection. No complication was observed. Botulinum therapy with 100 IU of Xeomin proved effective at resolving salivary fistula. Botulinum therapy is an effective treatment for symptoms of salivary duct stenosis in patients for whom minimally invasive procedures have failed. Botulinum therapy can also be used for the treatment of salivary fistulas.

A Functional Approach to Posttraumatic Salivary Fistula Treatment: The Use of Botulinum Toxin.

This manuscript highlights key aspects regarding the practical use of botulinum toxin for the conservative nonsurgical treatment of a rarely encountered, but significant posttraumatic complication-the parotid salivary fistula. It adds information to the scarce existing literature on the subject. The authors outline the main differences between postoperative and trauma-related parotid injury regarding salivary fistula treatment. A total of 6 patients with trauma-related salivary fistulas have been treated by Abobotulinum toxin A injections over the course of 5 years. The technique is detailed, describing the doses used in the presence of parenchyma and duct injuries, the location and number of injection points in relation to the wound pattern. The results were favorable, leading to the healing of the salivary fistulas in all patients, with 1 injection session, without additional conservative treatment. In our experience, the use of botulinum toxin is of great benefit for treating salivary fistulas in a traumatic context.

Management and Follow-up Results of Salivary Fistulas Treated With Botulinum Toxin.

OBJECTIVES/HYPOTHESIS: Salivary fistulas are a common minor complication of parotid surgery. botulinum toxin has repeatedly been reported to be an adequate treatment of this entity. To date, there is little scientific evidence for clinical decision making after appearance of a salivary fistula. STUDY DESIGN: Retrospective chart analysis of 16 patients who had been treated with botulinum toxin for salivary fistula. METHODS: All patients who had been treated for salivary fistula at a tertiary referral hospital from 2010 to 2016 were included. Patient files were used to obtain characteristics of patients, treatment, and follow-up. RESULTS: Sixteen patients with salivary fistula received 27 injections of botulinum toxin. Nine patients required one injection for the fistula to heal, five patients needed two injections, and one patient needed three and four injections, respectively. No patient underwent additional surgery or radiotherapy. We observed no adverse effects in any patient treated with botulinum toxin. CONCLUSIONS: In most cases of salivary fistula, injections of botulinum toxin are a valid treatment. If the initial injection is not successful, injections may be repeated once. Otherwise, revision surgery should be considered. In general, treatment with botulinum toxin should be commenced in an earlier stage and with higher dosages.

Orocutaneous fistulas of odontogenic origin presenting as a recurrent pyogenic granuloma

Orocutaneous fistulas, or cutaneous sinuses of odontogenic origin, are uncommon but often misdiagnosed as skin lesions unrelated to dental origin by physicians. Accurate diagnosis and use of correct investigative modalities are important because orocutaneous fistulas are easily confused for skin or bone tumors, osteomyelitis, infected cysts, salivary gland fistulas, and other pathologies. The aim of this study is to present our experience with a patient with orocutaneous fistulas of odontogenic origin presenting as recurrent pyogenic granuloma of the cheek, and to discuss their successful treatment.
