Active clinical trials for "Parotid Neoplasms"

This clinical trial studies the effect of customized 3 dimensional (3D) printed oral tents on patients with head and neck cancer who are receiving radiotherapy. Oral stents are made from the impression of patients' mouth and cover patients' teeth and gums during radiation therapy. A customized, 3D-printed oral stent may help to reduce mouth blisters and/or sores that may develop in patients while receiving head and neck radiation therapy.

Comparison between Ultrasound-Guided Ethanol Sclerotherapy (UGES) & surgical excision in management of warthin tumor of parotid gland.

Parotid neoplasm consists of a wide range of benign and malignant lesions, and parotidectomy has been the mainstay for management of these neoplasms. Within the parotid gland there are branches of the intra-parotid facial nerves, which are tiny in calibre and are prone to injury to injury during operation. It has been reported in recent retrospective view that the incidence of temporary and permanent facial nerve injury were 9.2% and 5.2% respectively, the risk of which increased with old age, malignant tumour and revision surgery. Traditional the incidental of facial nerve injury is reduced by intra-operative facial nerve monitoring and surgical magnification, while imaging has limited role in aiding this purpose. However with advancement in MRI technique high resolution three-dimensional sequences (i.e. neurogram sequences) are available for better visualization of branches of facial nerves. The investigators would therefore aim to demonstrate additional efficacy of these techniques and also to compare with conventional 3D post-contrast anatomical imaging studies in the localization and visualization of the facial nerve branches in patients with tumour. With better pre-operative imaging, the investigators hope to reduce the chance of facial nerve injury in these patients.

usefulness of the methylene blue staining for identification of facial nerve in parotid gland surgery

in these study we analyze pattern of parotid gland neoplasms according to histopathological types, most common type clinical presentation and type of surgical treatment(superficial parotidectomy or total parotidectomy radical parotidectomy

st visit: Inclusion, 3Tesla injected parotid MRI performed as part of routine care for characterization, to which two specific high resolution sequences will be added. Evaluation of the exact position of the parotid tumor relative to the trunk of the facial nerve and its first branches, classification into two categories: on contact (≤ 5 mm) or at a distance (> 5 mm). nd visit: Surgical intervention of the parotid tumor. The surgeon will specify the same data as that collected by the radiologists after the MRI. rd visit: Post-operative consultation in the week following the intervention. The surgeon will look for the occurrence of post-operative facial paralysis.

The goal of this observational study is to describe the prevalence of typical and atypical signs and symptoms of Frey's syndrome, the affected areas and the severity of each symptom/sign. Participants will be asked will asked about Presence or the absence of: a. gustatory sweating; b. gustatory flushing; c. gustatory itching; d. paresthesia; e. pain Grade of severity: a. absence; b. mild; c. moderate; d. almost severe; e. severe Affected area: a. preauricular; b. retroauricolar; c. temporal; d. retrangulomandibular; e. cheek

The parotid has a close relationship with the extra temporal course of the facial nerve. The study aimed to evaluate the accuracy and safety of trident landmark during superficial parotidectomy in the identification of the facial nerve trunk.

This is a protocol to govern the prospective trial of facial nerve monitoring in patients undergoing parotidectomy with an eye towards interpreting if the facial nerve monitor provides useful information to operating surgeons and if the information provided by the facial nerve monitor can predict degrees of postoperative facial nerve paresis. Additionally, the study will determine if performing daily facial rehabilitation exercises provides a benefit in reducing time to recovery of temporary post-parotidectomy paresis.
