Treatment of Postparotidectomy Fistulae with Fibrin Glue

A case report on role of hypertonic saline solution in management of parotid fistula

Introduction

Parotid fistula is an uncommon consequence of surgical or non-surgical trauma to the parotid gland or the area surrounding it. To treat it, a variety of pharmacological medicines and surgical techniques are used, each with their own set of benefits, drawbacks, and patient preferences.

Case Presentation

We present the successful care of a young female with post-traumatic parotid fistula using hypertonic saline injections into the parotid substance, which is a simple yet efficient approach of treating this abnormality.

Discussion

Thermodynamic and physicochemical calculations suggest that hypertonic saline solutions work to close parotid fistula by causing conformational denaturation of the cell membrane proteins in situ and saline can be diluted to a point where there will be no cellular toxicity. It is advised that temperature of the saline should be raised above body temperature to enhance the fibrosing property of physiologic saline.

Conclusion

The use of hypertonic hot saline injections combined with compression dressing is a cost-effective, patient-friendly, and almost complication-free approach of treating parotid fistulas with promising results.

Parotid fistula is an uncommon consequence of surgical or non-surgical trauma to the parotid gland.

The Offprint of an Abnormal Pre-Parotidectomy Electrodiagnostic Finding in a Normally Functioning Facial Nerve: Correlation with Intraoperative Findings, Histology and Postoperative Facial Nerve Function

The aim of this study was to search for associations between an electrodiagnostically abnormal but clinically normal facial nerve before parotidectomy and the intraoperative findings, as well as the postoperative facial nerve function. The records of all patients treated for parotid tumors between 2002 and 2021 with a preoperative House–Brackmann score of grade I but an abnormal electrophysiologic finding were studied retrospectively. A total of 285 patients were included in this study, and 222 patients had a benign lesion (77.9%), whereas 63 cases had a malignant tumor (22.1%). Electroneurographic facial nerve involvement was associated with nerve displacement in 185 cases (64.9%) and infiltration in 17 cases (6%). In 83 cases (29.1%), no tumor–nerve interface could be detected intraoperatively. An electroneurographic signal was absent despite supramaximal stimulation in 6/17 cases with nerve infiltration and in 17/268 cases without nerve infiltration (p < 0.001). The electrophysiologic involvement of a normal facial nerve is not pathognomonic for a malignancy (22%), but it presents a rather rare (~6%) sign of a “true” nerve infiltration and could also appear in tumors without any contact with the facial nerve (~29%). Of our cases, two thirds of those with an anatomic nerve preservation and facial palsy had already directly and postoperatively recovered to a major extent in the midterm.

Congenital Parotid Fistula: Surgical Management in Two Infants and Review of Literature

Congenital salivary gland fistulas are uncommon. They develop as a result of abnormalities of the first and second branchial arches. Operative and nonoperative methods of management have been described. We report two rare cases of congenital parotid fistula presenting to us in infancy that were managed surgically.

Transdermal scopolamine for the prevention of a salivary fistula after parotidectomy

Our aim was to investigate whether perioperative transdermal application of scopolamine could help to prevent fistulas after parotidectomy, and to this end we retrospectively studied the records of all patients (n=645) who had benign parotid tumours treated by partial parotidectomy between 2011 and 2016. We found that scopolamine led to a significant decrease in the incidence of salivary fistulas from 54/371(15%) in the group not given it to 10/274 (4%) in the group given it (p<0.0001). The "number needed to treat" was 9.17. There was a relatively low incidence of all adverse effects after scopolamine. Our results are encouraging. Thorough consideration of the contraindications and a knowledge of the potential adverse effects are crucial for its successful implementation.

Hypertonic saline solution for management of parotid fistula: A case report

The management of parotid fistulae has been unsatisfactory in the past, and numerous methods of treatment with varying success and morbidity have been described. A case of parotid fistula caused by damage to glandular elements during a transparotid approach for a subcondylar fracture reduction is reported. This paper presents a simple but effective and conservative method of treating this complication with the use of hot hypertonic saline.

Use of 2-Octyl-Cyanoacrylate in surgical closing of Postparotidectomy salivary fistulas

A salivary fistula is one of possible postoperative complications in the surgery of parotid gland tumors. We present three cases of postparotidectomy salivary fistulas, successfully treated by surgical access using 2-octyl-cyanoacrylate while closing the skin layer. The previous treatment of these cases by other therapeutic options did not give satisfactory results. In a 5-year follow-up period there were no signs of fistulas relapses. The surgical access with use of 2-octyl cyanoacrylate can be one of therapeutic options for the closing of postparotidectomy salivary fistulas, especially in cases where other therapeutic accesses are not successful.

Use of hypertonic saline in the management of parotid fistulae and sialocele: a report of 2 cases

Parotid fistula is a well known complication of parotidectomy or penetrating injury of the parotid gland. Fistulae may be internal or external, but simple internal fistulae are of no surgical interest. In cases of external fistulae, the principles of management aim at the return of normal parotid function in both acute and chronic parotid injury, but sometimes the alternative is to depress parotid secretions to allow natural healing process to seal the injury.The paper highlights the indications, techniques, advantages and disadvantages of using osmotic sclerosant for the management of parotid fistulae. We used warm hypertonic saline injections within the glandular substance to cause rapid fibrosis of the gland in 2 patients of chronic parotid fistulae.This technique is a simple and effective method of dealing with salivary leak. Its ease of performance, effectiveness; minimal surgical risk and minor cost are the advantages over other available options.
