Meta-Analysis
PURPOSE
At present, perineural invasion is used as a histologic indicator of aggressive salivary gland disease. In other head and neck malignancies, perineural invasion impacts staging of cancer lesions and therefore affects treatment options.
OBJECTIVE
To compare survival outcomes in primary parotid malignancies with and without perineural invasion.A systematic review pooled data from the scientific literature in patients with any primary parotid malignancy to investigate the prognosis of those with perineural invasion.
DATA SOURCES
PubMed (Medline), Scopus and Cochrane databases were queried from inception to July 2020 without any initial search constraints. Additional publications were included from review of pertinent articles.
STUDY SELECTION
Our inclusion criteria included primary parotid cancers with reported perineural invasion on survival outcomes. Exclusion criteria were non-English language text, non-human studies, reviews, textbooks, abstracts, case reports and case series. Two authors independently reviewed articles for inclusion. Of the initial 465 records, 83 articles were reviewed in full to yield a final collection of 14 studies.
DATA EXTRACTION AND SYNTHESIS
PRISMA-p guidelines were used in the reporting of our studies. A MOOSE Checklist was also used. MINORS criteria were applied to assess risk of bias. Random-effects models were used to estimate pooled effect sizes. No institutional review board review was needed for our study.
MAIN OUTCOMES AND MEASURES
Primary study outcomes were set prior to data collection and included overall survival (OS), disease-free survival (DFS), disease-specific survival (DSS) and distant-metastasis-free survival (DMFS) in patients with and without perineural invasion.
RESULTS
Fourteen studies contributed to this meta-analysis. Compared to patients without perineural invasion, the pooled rate of mortality (HR = 3.64), time to recurrence (HR = 3.56), disease-specific mortality (HR = 2.77) and distant metastasis (HR = 3.84) was significantly higher for patients with PNI (all p <.001). Controlling for perineural invasion status, no moderator was associated with these survival outcomes (all p >.05). Given the clinical severity of perineural invasion, few studies were null as shown in a panel of publication bias plots.
CONCLUSION
Perineural invasion portends a poor survival outcome in patients with parotid malignancies.

Meta-Analysis Review
It is important to define the accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis of Warthin tumor (WT). This systematic review and meta-analysis evaluated the accuracy of FNAC in the diagnosis of WT in the parotid gland and WT growth rate. For determination of FNAC accuracy, 17 studies, encompassing 1710 cases, were included. Pulled random model estimates of sensitivity, specificity, PPV, and NPV were 93.7% (95%CI: 92.1, 95.3), 97.9% (95%CI: 97, 98.9), 93.3% (95%CI: 91.5, 95.1), and 97.4% (95%CI: 96.4, 98.4), respectively. FNAC is highly reliable for the diagnosis of WT of the parotid. The high PPV value suggests that patients with a cytological diagnosis of WT of the parotid may be assigned to active surveillance.

OBJECTIVE
Various prognostic factors are associated with the survival of patients with parotid mucoepidermoid carcinoma (MEC). The aim of this systematic review is to summarize the clinical and pathologic prognostic factors on survival outcomes in patients with parotid MEC.
DATA SOURCES
Articles published from database inception to July 2020 on OVID Medline, OVID Embase, Cochrane Central, and Scopus.
REVIEW METHODS
Studies were included that reported clinical or pathologic prognostic factors on survival outcomes for adult patients with parotid MEC. Data extraction, risk of bias, and quality assessment were conducted by 2 independent reviewers.
RESULTS
A total of 4290 titles were reviewed, 396 retrieved for full-text screening, and 18 included in the review. The average risk of bias was high, and quality assessment for the prognostic factors ranged from very low to moderate. Prognostic factors that were consistently associated with negative survival outcomes on multivariate analysis included histologic grade (hazard ratio [HR], 5.66), nodal status (HR, 2.86), distant metastasis (HR, 3.10-5.80), intraparotid metastasis (HR, 13.52), and age (HR, 1.02-6.86). Prognostic factors that inconsistently reported associations with survival outcomes were TNM stage, T classification, and N classification.
CONCLUSION
Histologic grade, nodal status, distant metastasis, intraparotid metastasis, and age were associated with worse survival outcomes. These prognostic factors should be considered when determining the most appropriate treatment and follow-up plan for patients with parotid MEC.

Review
Different therapeutic methods for chronic drooling in paediatric patients with neurological problems have been described in the scientific literature. However, there is no consensus on the ideal strategy of treatment. The aim of this study was to compare botulinum toxin injection therapy and surgical modalities to control drooling in paediatric patients with neurological disorders. A systematic literature search was conducted on nine electronic databases for publications until April 2020. Six articles were included with a total sample of 209 patients, 67.4% (n = 141) of whom had cerebral palsy. All studies used injections of botulinum toxin type A with application to the submandibular and/or parotid salivary glands. The surgical treatments were duct ligation in the parotid and/or submandibular salivary glands, duct relocation in the submandibular salivary glands, and glandular excision of the submandibular and sublingual salivary glands. There were complications in only 16.1% (n = 27) of the sample (11 cases due to botulinum toxin application and 16 due to surgery). Drooling control was assessed by objective and subjective measures. Although surgical procedures presented a higher risk of adverse effects than botulinum toxin type A in all the studies and measurements performed, they presented larger and longer-lasting positive effects on drooling. We suggest bilateral submandibular duct relocation with bilateral sublingual gland excision or isolated bilateral submandibular duct ligation, which were the surgical techniques with the largest samples in this review. Nevertheless, further studies are necessary to compare samples with botulinum toxin type A and surgical treatment.

Review
OBJECTIVE
Botulinum toxin A is known to be effective and safe in managing sialorrhea in pediatric patients; however, there is no consensus on a protocol for optimal injection sites and appropriate dosing for injection.
METHODS
This review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol. PubMed, EMBASE, and other databases were queried to identify articles that evaluated botulinum toxin type A for the treatment of sialorrhea in the pediatric population. A total of 405 studies were identified. After applying inclusion and exclusion criteria, 31 articles were included for review.
RESULTS
A total of 14 studies evaluated 2-gland injections, and 17 studies evaluated 4-gland injections. Of the 31 studies included, one study assessed incobotulinumtoxinA (Xeomin) the remaining all used onabotulinumtoxinA (Botox). For 2-gland injection studies, a combined total of 899 participants were reviewed, where 602 participants received 50 units into their submandibular glands, while 262 participants received 30 to 50 units. Among 4-gland injection studies, there was a combined total of 388 participants, with the most prevalent dosage utilized being 60 to 100 units in 230 participants, followed by 100 units total in 77 participants. The most common adverse event was dysphagia which resolved in nearly all cases. Three studies aimed to examine 2-gland versus 4-gland injections, with 2 of the studies concluding 4-gland injection was superior.
CONCLUSIONS
The strength of evidence suggests that the dosing of 50 units total of onabotulinumtoxinA to the submandibular glands is safe and effective in the pediatric population. For 4-gland injections, bilateral submandibular and parotid gland injections of 60 to 100 units total is the safe and effective dosage. There is no substantial evidence comparing 4-gland injections to 2-gland injections, but research thus far suggests 4-gland injections to be superior. Future study is needed to evaluate incobotulinumtoxinA and abobotulinumtoxinA dosages in the pediatric population.

Review
OBJECTIVES
To evaluate surgical approaches and outcomes of pleomorphic adenoma of parotid gland in pediatric population.
METHODS
A systematic search of PubMed and EMBASE was performed to identify articles reporting surgical treatment of pleomorphic adenoma of the parotid gland in children. A qualitative analysis on results was conducted.
RESULTS
Our search included 23 retrospective studies. The number of children with pleomorphic adenoma underwent surgical treatment were 330. Superficial parotidectomy is the most reported type of surgery, total parotidectomy is performed when the tumor occurs in the deep lobe or in revision surgery and limited excisions in selected case of small lesions mainly in the tail of parotid gland. The rate of recurrences after surgery ranged from 0% to 44.4%. Revision surgery was performed in all cases of recurrences. Considering major complications, transient facial paralysis was observed from 0% to 50% of cases after primary and/or revision surgery; Frey's syndrome from 0% to 14.3% of cases regardless of the type of surgeries.
CONCLUSION
Surgical treatment of pleomorphic adenoma of parotid gland in children requires a tailored approach based on the location and extent of the tumor with the main aim of complete excision of the neoplasm. Appropriate surgical approach results in a decrease of recurrence rate and morbidity. Surgical skill is needed to reduce complication rates especially in children.

Meta-Analysis Review
Mammary analogue secretory carcinomas (MASCs) of the parotid gland are considered as low-grade malignancies with good clinical outcome but lacking data regarding prognostic factors. We performed meta-analysis assessing prognostic factors for disease-free survival (DFS) and overall survival (OS) in 256 patients with MASCs of the parotid gland. A total of 73 studies have met the inclusion criteria and 76.3% of patients were seen with T1 and T2 tumors and negative neck nodes. Lymph node metastasis (57.4%) and distant recurrences (46.2%) were particularly found in T4 tumors (p < 0.001). DFS at 5 and 10 years was 77.9% and 47.2% compared to 88.1% and 77.2% for OS at the same time points. Male sex, T3-T4 tumors, and recurrent disease represented independent worse prognosticators for survival outcome. Altogether, parotid gland MASCs show good long-term outcome, but T4 tumors behave significantly more aggressive and require extended treatment strategies along with close follow-ups.
