Surgical treatment in non-neoplastic parotid disease: indications and results.

Non-neoplastic disease of the parotid gland is an important entity, requiring differential diagnosis and management. The incidence of non-neoplastic parotid disease (NNPD) is increasing and makes up about 25% of cases for which parotidectomy is indicated. NNPD can be categorized as type I (asymptomatic soft diffuse enlargement or circumscribed firm nodular enlargement) or type II (inflammatory lesions with recurrent pain and swelling, obstructive or nonobstructive). Concern over possible malignancy is highest in type I nodular lesions and least in type II lesions. Operative treatment may be indicated for exclusion of tumour, relief of recurrent pain and swelling and patient anxiety. In 62 patients with NNPD who were operated on, the relevant clinical factors included radiation, diabetes, tuberculosis, Sjögren's syndrome and pulmonary sarcoidosis. Superficial parotidectomy was effective, being associated with low morbidity, and can be recommended as acceptable treatment, providing there is a complete patient history and operation is carried out by a surgeon experienced in parotid surgery.

[Contribution of echotomography to the study of parotid diseases].

Echotomography of the parotids in 88 patients was successful in detecting normal parotid morphology or inflammation of the parenchyma (parotitis) in 100 p. cent of such cases, and detecting the precise localization of tumors (adenopathies or intraparotid tumors) up to 3 mm in diameter in 93 p. cent of cases. Though cystadenomas do not provide a specific image, their appearance is typical. Positive diagnosis was possible in 85 p. cent of mixed tumors of 1 cm diameter or more, and in 5 out of 7 cases of malignant lesions. The diagnostic value of this examination is markedly limiting that of parotid sialography.

[The study of magnetic resonance sialography in diagnosing parotid diseases].

OBJECTIVE: To study the feasibility of diagnosing parotid disease with magnetic resonance sialography (MRS) and to select the optimal scanning sequence. METHODS: Twenty-three patients with parotid gland disease and 5 normal adults received sialography using magnetic resonance imaging technique and several sequences (including IR-FSE, FSE, SS-IR-FSE, SS-FSE) were used. After first scanning, the patients were scanned respectively 3 and 10 minutes after buccal application of vitamin C. And MR images of duct obtained. The images of parotid duct system were analysed and evaluated according to their displaying effects. Qualitative diagnosis was made based on MRI and those diagnosis were compared with pathological diagnosis after operation. RESULTS: Images of MR sialography clearly displayed the main duct and its branches of parotid gland and the pathological changes of duct, such as narrow, expanded, stoppage. Of the scanning sequences, IR-FSE was superior to others in manifesting the parotid gland duct (P < 0.05). The performance of images after being given vitamin C did not significantly improve the displaying effect. The accurate rate of qualitative diagnosis was 95.6%. CONCLUSIONS: MR sialography can clearly display the parotid ducts and their pathological changes. The accurate rate of qualitative diagnosis of parotid disease was higher than that X-ray sialography.

Surgical parotid disease in Nigeria: a review of 100 cases.

100 cases of surgical parotid disease are reviewed. Parotid cyst was the commonest non-neoplastic disease, followed by a parotid fistula. 73% of the cases were neoplastic conditions of which approximately 50% were malignant and the patients were much younger than those reported in other series.

[Determination of serum amylases in parotid diseases].

In 50 patients, the majority of them suffering from parotid diseases, serum isoamylases were determined (salivary S-type and pancreatic P-type). After sialography, there was in most cases a slight increase in isoamylase level. Salivary amylase does not seem to be a suitable marker for parotid neoplasms.

Parotid disease and human immunodeficiency virus infection in Zambia.

Among the salivary glands the parotid is unusual in that it contains lymphoid tissue within its capsule. The focus of infection with human immunodeficiency virus (HIV) is the lymphatic system and this results in a specific HIV-related pathology in the parotid. This 2-year surgical audit of parotid disease in HIV-infected patients in Lusaka shows patients presenting with parotid lymphadenopathy, bilateral diffuse parotid enlargement and parotid lymphoepithelial cysts. Clinical presentation and management are discussed.

Benign parotid diseases of childhood.

A 25-year retrospective study of 63 pediatric surgical cases of benign parotid disease was done. Inflammatory disorders accounted for 34 of the cases. The remaining 29 non-inflammatory conditions included vasoformative, solid, and cystic lesions and were nearly always asymptomatic.

Surgical management of chronic parotid disease.

This is a retrospective review of a single surgeon's experience over a 20-year period, and covers the presentation, investigation, histology, management and complications of the surgical treatment of chronic parotid disease. There were 46 superficial parotidectomies (23 with ductal ligation); 3 required removal of calculi and there was one ductoplasty and one total parotidectomy. There were 28 cases of temporary palsy of the VIIth cranial nerve (55%, mean duration 4 months) and this was predominantly panfacial (79%). There were no cases of permanent palsy. Five patients who initially had a superficial parotidectomy required subsequent total parotidectomy for recurrent disease (11%). We have now adopted a policy of near total parotidectomy for the surgical treatment of chronic parotid disease.

Diagnostic ultrasound imaging of parotid disease--a contemporary clinical perspective.

Diagnostic ultrasound provides fast, simple screening soft tissue information for evaluation of both parotid glands on the same single image display. This information augments the findings on history and physical examination and directs further radiologic studies if indicated. This manuscript attempts to establish the role for diagnostic ultrasound in the evaluation of patients with diffuse and focal parotid disease. It also attempts to establish a more definitive role for diagnostic ultrasound in relation to other diagnostic imaging modalities.

Parotidectomy for benign parotid disease at a university teaching hospital: outcome of 963 operations.

OBJECTIVE/HYPOTHESIS: The objective of this study was to analyze the perioperative and long-term complications after standardized lateral and total parotidectomy for benign parotid tumors and chronic parotitis with special regard on the training skill of the surgeons at a university teaching center. All teaching operations were performed under strict microscopic control and supervision of experienced surgeons. STUDY DESIGN: The authors conducted a retrospective unicentric study in a tertiary university center. METHODS: Medical records of 963 lateral and total parotidectomies treated from 1986 to 2004 were analyzed with regard to perioperative and long-term complications. The surgeons' expertise to perform a parotidectomy was classified as beginner (0-20 parotidectomies performed), advanced (21-50), experienced (51-100), or highly experienced (>100). RESULTS: Eighty-five percent of the cases were primary operations (85%) and 15% revision operations. A lateral parotidectomy was necessary in 61% and total parotidectomy in 39%. The mean operation time was 192 minutes. The incidence of transient facial nerve dysfunction was 25%, and 6% for permanent weakness, respectively. Treatment for Frey's syndrome was performed in 5%. First recurrence for pleomorphic adenoma was observed in 2% and for Warthin's tumor in 3%. Significantly more complications were seen after total parotidectomy and in revision cases. Beginners and advanced surgeons (operated 41% of the cases) needed a longer operation time than experienced and highly experienced surgeon (59% of the cases). The surgeon's expertise had no influence on the incidence of complications. CONCLUSIONS: Standardized education in lateral and total parotidectomy for treatment of benign parotid disease under precise microscopic control is safe, demonstrates good results, and has low perioperative and long-term morbidity.

[Imaging diagnosis of parotid diseases--a comparison of methods].

Thirty-five patients with parotid gland disorders were ultrasonographically examined with a "small parts" scanner, as well as with high-resolution computed tomography, and conventional and digital subtracted sialography. The results were compared with clinical, surgical, and pathomorphological data. In cases of parotid gland masses, the sensitivity of sonography, CT, and sialography was 100%, 81%, and 70% respectively, while in cases of sialadenitis, sensitivity was 38%, 50%, and 75%. The image-quality of digital subtracted sialography was superior to conventional sialography in 94% of cases, the same in 6%, and inferior in none of the cases. It is concluded that in all cases of parotid gland diseases ultrasound should be the first imaging method. If a tumor is confirmed, no further pretherapeutic imaging will be necessary in most cases. If a tumor is not confirmed, digital subtracted sialography should be employed to visualize inflammatory changes.

A comparative analysis of the clinical, sialographic, and pathologic findings in parotid disease.

In review of the clinical and sialographic ability to predict parotid pathology, it was found that the clinical exam was consistently more accurate. Sialographic findings and histopathology were compared in 119 patients who underwent 120 sialograms and subsequent parotidectomies. Sialography alone was able to diagnose a malignant tumor in only 8 per cent (1/13) of the cases. The sialogram proved most helpful for the clinician in the management of patients when the diagnosis was calculus, obstruction, or sialectasia. On the other hand, mass lesions in or adjacent to the parotid, diffuse enlargement of the gland, or conditions such as masseter muscle hypertrophy are probably better evaluated with newer CT techniques in conjunction with sialography or without sialography.

[Parotid diseases in high-resolution real-time-tomography].

Ultrasound examination of the parotid by grey-scale real time is a method which has hardly been used so far. By using a high resolution 5 MHz probe and a water bag, it is possible to obtain detailed information concerning the type, extent, margins and consistency of pathological changes in the parotid. The margins of benign lesions are always clearly defined, whereas malignant processes usually have ill-defined margins. Further differentiation is possible from the type of echo. Normal parotids have a homogeneous structure, similar to the thyroid, with a medium to bright grey-scale value; solid, cystic or inflammatory lesions present irregular or inhomogeneous structures. The sonographic appearances are illustrated by the findings in 43 patients and are compared with their histology.

Periparotid lupus erythematosus panniculitis. Clinicopathologic correlation of two cases presenting as primary parotid disease.

Lupus erythematosus (LE) panniculitis, also called lupus profundus, is an uncommon but well-established manifestation of both chronic cutaneous (discoid) LE and systemic LE. Although LE panniculitis characteristically may involve the face, specific parotid and periparotid involvement has not, to the best of our knowledge, been previously reported. We describe the clinicopathologic correlation of two cases of LE panniculitis that presented as apparent primary parotid parenchymal disease; one as a neoplasm, the other as parotiditis. Failure to recognize LE panniculitis resulted in prolonged periods of inappropriate therapy and significant morbidity, including an unnecessary parotidectomy. Lupus erythematosus panniculitis has well-established histologic criteria that should be considered in the differential diagnosis of an unexplained parotid mass.
