Saliva is actively produced in high volumes relative to the mass of the salivary glands and is almost completely controlled extrinsically by both parasympathetic and sympathetic divisions of the autonomic nervous system. Some researchers used bilateral tympanic neurectomy for patients with ptyalism (drooling) with good initial results. Others advocated bilateral parotid duct rerouting ± bilateral submandibular gland excision for long-term treatment of drooling. Intra-glandular Botulinum toxin may also have good results for patients with hyper-sialorrhea. Most resting salivary gland flow arises from the submandibular glands and surgery should focus on this gland to control uncontrolled sialorrhea.","PeriodicalId":242362,"journal":{"name":"Diagnostic Techniques and Therapeutic Strategies for Parotid Gland Disorders","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133022433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Causes of inflammatory disorders of the parotid gland include viral infections; bacterial infections; recurrent parotitis of childhood; papillary obstructive parotitis; granulomatous sialadenitis; autoimmune sialadenitis including Mickulicz disease, Sjogren's syndrome; and other autoimmune sialadenitis such as Wegener's granulomatosis, Kimura's disease, and chronic sclerosing sialadenitis. Sialadenosis is a chronic, diffuse, non-inflammatory, non-neoplastic disorder causing diffuse enlargement of salivary glands, usually the parotid glands. Grossly, there is only diffuse enlargement of the affected gland, and histologically, the condition is characterized by acinar hypertrophy and fatty infiltration. Patients present with painless, soft, and diffuse enlargement of both parotid glands. Treatment in the form of controlling the underlying disorder or withdrawing the incriminated drug helps sialosis to resolve.","PeriodicalId":242362,"journal":{"name":"Diagnostic Techniques and Therapeutic Strategies for Parotid Gland Disorders","volume":"77 13","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120824900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include different types of parotidectomy (superficial or lateral parotidectomy, radical parotidectomy, and extended total parotidectomy), limited procedures (partial superficial parotidectomy and extra-capsular dissection), and enucleation (extra-capsular and intracapsular). Indications include neoplasms, inflammatory lesions, salivary duct stones, and sialorrhea. Post-operative complications are discussed. These are either early complications (facial nerve palsy, bleeding/hematoma, surgical site infection, skin flap necrosis, salivary fistula/sialocele, seroma, external otitis, and trismus) or late complications (Frey's syndrome, hypertrophic scar/keloid, unsightly scar, soft tissue defect, and recurrence).","PeriodicalId":242362,"journal":{"name":"Diagnostic Techniques and Therapeutic Strategies for Parotid Gland Disorders","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121127482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It either occurs “de-novo” or “on top of pleomorphic adenoma.” There is no sex predilection, and the age of developing this cancer is usually above 50 years. Malignant tumors are as varied as their benign counterparts. Certain tumors are “low-grade” (polymorphous low-grade adenocarcinoma, acinic cell carcinoma, epithelial-myoepithelial carcinoma), while others are “high-grade” (salivary duct carcinoma, large cell carcinoma, and small cell carcinoma). The first echelon lymph node (LN) of metastases is the intra- and peri-glandular nodes. The next echelon is level II LNs. Hematogenous spread occurs very late and is mainly to the lungs and bones. However, adenoid cystic carcinoma tends to grow through peri-neural lymphatics with increased risk of nerve involvement, intra-cranial extension, and increased rate of recurrence. In this chapter, characteristic features and management of the individual types of malignant parotid tumors will be discussed.","PeriodicalId":242362,"journal":{"name":"Diagnostic Techniques and Therapeutic Strategies for Parotid Gland Disorders","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116021405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
