Review
BACKGROUND AND PURPOSE
Parotid gland lymphoma (PGL) is a rare and challenging diagnosis. Different lymphomas can develop in the parotid gland, with the most common being the mucosa-associated lymphoid tissue (MALT) lymphoma, which originates directly from the glandular parenchyma. Other histologic subtypes arise from both intraglandular and extraglandular parotid lymph nodes. A consensus on diagnosis and treatment of PGL is still lacking, and published data is scarce and heterogeneous.
METHODS
We performed a systematic review of the literature, including studies published after 2001, when the WHO classification of lymphoid tumours was introduced.
RESULTS
Twenty retrospective studies were included in the analyses, eight of which focused exclusively on MALT lymphomas. Final analysis included 612 cases of PGL, with a 1.68:1 F/M ratio. MALT lymphoma was the most common histology, followed by follicular and diffuse large B-cell lymphoma. Most cases were low stages (IE/IIE acc. Ann Arbour, 76.5%) and only 10% of patients presented with symptoms, most commonly pain (4.8%) and B symptoms (2.2%). A high prevalence of associated autoimmune diseases was found, particularly Sjögren's syndrome, that affected up to 70% of patients with MALT lymphoma. In most cases diagnosis was achieved through parotidectomy (57.5%), or open biopsy (31.2%). Treatment strategies were either surgical, non-surgical or a combination of modalities. Surgery as a single-modality treatment was reported in about 20% of patients, supposing it might be a valuable option for selected patients.
CONCLUSIONS
Our review showed that the diagnosis and treatment of PGLs is far from being standardized and needs further, more homogeneous reports to reach consensus.

OBJECTIVE
Parotid neoplasms are a rare heterogeneous group of tumors with varied clinical presentation and behavior. Here we provide an evidence-based review of the contemporary approach to evaluation and surgical management of parotid tumors.
DATA SOURCE
PubMed and Web of Science Databases.
REVIEW METHODS
Searches of the PubMed and Web of Science databases were performed on subjects related to the diagnosis and surgical management of parotid neoplasms. Particular emphasis was placed on the following areas: evaluation of parotid tumors, including imaging workup and the utility of fine-needle aspiration; extent of surgery of the primary lesion, including the extent of parotidectomy as well as oncologic management of the facial nerve; the extent of surgery of involved and at-risk cervical lymphatics; and parotid bed reconstruction. Articles published from 2014 to the present were prioritized, supplementing with information from prior studies in areas where data are lacking.
CONCLUSION
A summary of the literature in these areas is outlined to provide an evidence-based approach to evaluation and management of parotid neoplasms.
IMPLICATIONS FOR PRACTICE
While data are available to help guide many aspects of workup and management of parotid neoplasms, further research is needed to refine protocols for this heterogeneous group of diseases.

The murine parotid salivary glands develop postnatally, shaping oral mucosal immunity in early and adult life. This protocol details the surgical removal of the parotid glands (parotidectomy) of mice. We also describe a protocol for saliva collection to enable manipulation and measurement of physiological and immunological salivary functions. Our saliva collection approach has been modified from published protocols to enable saliva collection from young mice, which can be challenging. For complete details on the use and execution of this protocol, please refer to Koren et al. (2020).

BACKGROUND
While salivary gland tumors constitute 5-6% of all head and neck tumors, they constitute 2-3% of all trunk tumors. About 3.8 per 100,000 of parotid tumors are diagnosed in the US each year, about 1300 to 1600 cases. The salivary gland cancer rate is 0.9 per 10000. The frequency of salivary gland tumors varies according to localization.
OBJECTIVE
In our study, we aimed to evaluate retrospectively the histopathological results, incidence, surgical treatment modalities and complications of parotid tumors operated in our clinic.
METHODS
We examined the patients who were operated for parotid gland tumor. The files of 136 patients who were admitted to the Otorhinolaryngology department of Dicle University Medical Faculty Hospital between January 2010 and April 2020 due to a parotid mass and underwent parotidectomy and whose pathology results were reported as benign or malignant parotid tumors were retrospectively scanned and included in the study. Patients' age, gender, FNAB cytology result, type of surgery, histopathological results after surgery and complications after surgical treatment were recorded.
RESULTS
A total of 136 patients, 73 (53.7%) male and 63 (46.3%) female, were included in the study. The mean age of the patients was 48.26±17.37 (min=14, max=83) years. Superficial parotidectomy was performed in 108 (79.4%) patients and total parotidectomy was performed in 28 (20.6%) patients. According to the histopathological results after surgery, 108 (79.4%) benign tumors and 28 (20.6%) malignant tumors were diagnosed. Accordingly, pleomorphic adenoma (47.8%) was the second most common with 65 patients, followed by Whartin tumor (25.7%) with 35 patients. The sensitivity (sensitivity) of FNAB was 85.2%, and the specificity (specificity) was 96.2%. The accuracy of FNAB was found to be 94.0%.
CONCLUSION
Good identification of the parotid mass preoperatively, together with both FNAB and radiological imaging methods, gains much more value in differentiating malignant and benign pathologies. While superficial parotidectomy is mostly sufficient in benign tumors, total parotidectomy-radical parotidectomy in malignant tumors and neck dissection should be considered in high-grade tumors even if there is no neck metastasis. Patients should be evaluated for RT and CT according to the tumor type after surgery.

PURPOSE
Sialocele and salivary fistula are recognised complications of parotid surgery and have been reported to be more common with less extensive parotidectomy. We investigated the efficacy of tissue sealant(Cunniffe et al., 2019) as an alternative to surgical drainage in terms of length of hospital stay (LOS), cost, and incidence of wound complications.
METHODS
The study comprised a retrospective review of a prospectively maintained parotidectomy database at a single tertiary Head and Neck referral centre between 2009 and 2020. Cases undergoing concomitant neck dissection or major skin resection were excluded. Patients were divided into Group 1 (without tissue sealant), and Group 2 (with tissue sealant). Patients were also divided based on extent of surgery 1) Extracapsular dissection/Partial superficial parotidectomy 2) Superficial/total parotidectomy.
RESULTS
Of 202 included patients, there were 146 in Group 1 (143 with drain), and 56 in Group 2 (7 with drain). Compared to Group 1, Group 2 had a significantly shorter LOS (mean 1.4 ± 0.98 versus 3.1 ± 1.29 days, p < 0.05) and estimated cost (€1386 versus €2736). There was no significant difference in the complication rates (15.8% Group 1 versus 10.7% Group 2, p = 0.50). Group 1 showed a higher incidence of complications in patients undergoing less extensive parotidectomy (19/70 versus 4/76, p = 0.02), whereas in Group 2, the difference was not significant (5/30 versus 1/26, p = 0.20).
CONCLUSION
The use of tissue sealant as an alternative to surgical drains after parotidectomy facilitates reduced LOS and cost savings without increase in morbidity.

Review
The sternocleidomastoid (SCM) flap has been used for a long time in protective coverage of major vessels, reconstruction of intraoral pharyngeal, closure of pharyngo-cutaneous fistulas, and augmentation of soft tissue defects in the oral and maxillofacial region. However, this flap is not yet commonly used due to doubtful blood supply to the flap. This flap offers favorable esthetic results, combined flap, rich vascularization, and the possibility of shifting the two heads of the muscle. Thus, this flap has been used broadly in the maxillofacial region to reconstruct the defects of the post-parotidectomy, mandible, pharynx, and floor of the mouth defects. Previous studies discussed the use of a SCM flap following parotidectomy. However, few studies explained the use of SCMs in facial reconstruction. This study aims to review published articles discussing the use of SCMs for facial reconstruction.

Surgery is the treatment of choice for tumours in the parotid gland. We evaluated complications following parotid surgery. We conducted a retrospective study on 554 patients undergoing parotid surgery for benign parotid tumours from 2012 to 2021. We analysed complication rates between extracapsular dissection (ECD) and superficial parotidectomy (SP). We found 19 capsular ruptures in patients undergoing ECD (5.34%) and five among those undergoing SP (2.52%) [p < 0,05]; 16 cases of temporary facial paralysis among those undergoing ECD (4.49%) and 35 in patients undergoing SP (17.67%) [p < 0,05]; and eight instances of permanent facial nerve paralysis in patients undergoing ECD (2.25%) [p > 0,05] and 13 in patients undergoing SP (6.56%). Among the mid-term complications described were: 22 salivary fistulas among patients operated with ECD (6.18%) [p > 0,05] and 17 in patients with SP (8.58%) 17 sialoceles in those who underwent ECD (4.77%) and seven with SP (3.53%) [p > 0,05]. Regarding late complications, we found: surgical wound dehiscence, pathological scarring (keloid), Frey's syndrome, and recurrence, which affected 45 patients with ECD (12.64%) and 21 with SP for dehiscence (10.6%) [p < 0,05]; 28 keloids in patients with ECD (7.86%) and 15 in patients with SP (7.57%) [p > 0,05]; 12 cases of Frey's syndrome in patients with ECD (3.37%) and 36 with SP (18.18%) [p < 0,05]; and finally 22 recurrences in patients who underwent ECD (6.18%) and 13 in patients who underwent SP (6.56%) [p > 0,05], including 30 in the 273 patients with pleomorphic adenoma and five in the 214 patients with Warthin's tumour. We can conclude that the onset of the different complications after parotid gland surgery are related to the surgery performed. Our data confirm that there is a tight relationship between type of surgery performed and type of complication.

UNLABELLED
Hydatidosis (Echinococcosis) is a disease caused by infestation of hydatid cysts in any organ of body but mainly liver (70% of cases). Hydatidosis of salivary glands is rare and necessitate computerized tomography for diagnosis while fine needle aspiration remains controversial procedure.
MATERIALS AND METHODS
6 patients diagnosed with hydatid cysts of parotid glands. These cases were admitted and treated at the maxillofacial surgery Clinic of the "AL-Ramadi" Hospital in Iraq. 5 patients were female and 1 male with age group was between 30 -50 years. The patients complained of painless unilateral swelling in parotid region and who were diagnosed hydatid cysts using CT. All cases were treated by superficial parotidectomy with cystectomy and preservation of facial nerve.
RESULTS
All hydatid cysts are CE1- type with no recurrences were reported in any of these cases. The postoperative edema was the most common complication. Other complications were not seen.
CONCLUSION
parotid hydatid cyst should be included in differential diagnosis of persistent parotid swelling especially those with history of hepatic hydatid cysts. Computerized tomography is the gold imaging that aid in diagnosis and classification of hydatid cysts. Most cases are CE1 type and Eosinophilia is a sign of concern in some patients. Surgical treatment remains the "gold standard" in therapy.

BACKGROUND
The goal of this review was to introduce endoscopic/robotic parotidectomy (EP/RP) and compare EP/RP against conventional parotidectomy (CP) regarding the intraoperative and postoperative parameters in the treatment of parotid tumors.
METHODS
A systematic literature search of medical databases (PubMed, Embase, and Cochrane Central Register of Controlled Trials) was performed from inception to November 2020 to generate relevant studies.
RESULTS
A total of 13 eligible studies (572 patients) were included for systematic review, and 7 out of 13 comparable studies for the quantitative synthesis of outcomes. Patients who underwent EP were characterized by less intraoperative bleeding volume, shorter incision length, and higher satisfaction postoperatively (WMD, 95% CI, -42.80; - 58.23 to -27.37; p < 0.01; WMD, 95% CI, -5.64; -7.88 to -3.39; p < 0.01; SMD, 95% CI, 1.88; 1.46 to 2.31; p < 0.01, respectively). However, operative time and risk of facial palsy exhibited no significant differences (WMD, 95% CI, -11.17; -26.71 to 4.34; p = 0.16; OR, 95% CI,0.71; 0.39 to 1.32; p = 0.28, respectively).
CONCLUSIONS
Our findings suggest that the current evidence does not adequately support EP is equally safe and effective as CP. In certain selected cases, endoscopic technology has its unique advantages. For patients with strong cosmetic needs, endoscopic or robotic techniques may be an alternative through adequate preoperative evaluations.
