Objectives : There are many reports on attempts to minimize complications and recurrences of tumor by several techniques for benign parotid tumor resection. The purpose of our study is to find out meaning of procedure without identifying main trunk of facial nerve compared to conventional parotidectomy. Material and Methods : We classified 121 patients into two groups. Patients who were underwent superficial parotidectomy or partial superficial parotidectomy were included in idenitification group(IF group), and patients who were treated with conservative partial parotidectomy or extracapsular dissection without identification of main trunk of facial nerve were included in the non-identification group(NF group). We analyzed the location of tumor, operation time, mean drainage duration, complication, recurrence and cosmetic satisfaction in two groups. Results : NF group has shorter operation time and mean drainage duration than IF group, however there is no significant difference in complication and recurrence between two surgical techniques. The Cosmetic satisfaction was similar between two groups. Conclusion : Limited parotidectomy without finding main trunk of facial nerve may be reliable option for benign parotid tumors because it has advantages such as less operation time and mean drainage duration without increasing in recurrence or complication rate.

A metastasizing pleomorphic adenoma originating from the parotid gland is a rare form of neoplasm. The neoplasm is a histologically benign, but clinically controversial entity. Herein, a case report of a pleuro-pneumonectomy of a metastasizing pleomorphic adenoma in the right lung is described. A 57-year-old man, who underwent resection of parotid gland due to a pleomorphic adenoma, presented with multiple metastases on the right lung, mediastinum, pericardium and intercostal muscle. The metastatic lesions were composed of a benign pleomorphic structure.

This is a case report on the lipoma of the parotid gland. Lipomas are common soft tissue neoplasms found only rarely in the region of the parotid gland, and therefore often not considered in the initial differential diagnosis of a mass presenting in this region. Clinically they can be confused with other being lesions and there was no reliable methods to make a preoperative diagnosis of the lipoma until 1980's; however, CT allows a specific diagnosis to be made in virtually all case. We experienced that CT imaging permit the preoperative diagnosis of the lipoma, so could remove it preserving the parotid gland.

Introduction : No drain technique during parotidectomy had been introduced to reduce postoperative morbidity and to minimize hospital stay in a few previous publications. Since the authors have applied this technique in select patients for several years, we wanted to evaluate the feasibility and usefulness of no drain parotidectomy. Material & Methods : We retrospectively reviewed the medical records of 96 patients who underwent superficial or total parotidectomy by one surgeon from May 2005 to July 2012. The decision on drain insertion was made by the operator at the end of the surgery. The patients were categorized as drain insertion group and no drain group. Results : The patients who have smaller tumors and benign lesions were more frequently chosen into no drain group. Hospital stay was shorter in no drain group than in drain insertion group. Although no drain group showed increased number of acute complications such as seroma and hematoma, the complications were mild and could be controlled easily at the outpatient clinic. Conclusion : No drain technique during parotidectomy could be done relatively safely in select patients and it could reduce hospital stay.

Pleomorphic adenoma of the parotid gland typically presents as painless, mobile mass of long duration, and originate in the superficial lobe but, more rarely these tumors may involve the deep lobe of the parotid gland. The average size of a parotid neoplasm is 2 to 4 cm. The effective treatment of parotid pleomorphic adenoma is surgical excision. The simple excision or enucleation resulted in recurrence rate of 45% in benign tumor. Therefore, the superficial parotidectomy with identification and preservation of the facial nerve is now the most widely accepted surgery. We report a case of the huge pleomorphic adenoma of the left parotid gland in a 67-year-old man who complained the large mass, measured about $10\times7\times5$cm-sized, in front of the left ear and on the mandibular ascending ramus. The diagnosis was confirmed by the clinical examination, computed tomographic scan, fine needle aspiration, and incisional biopsy. Superficial parotidectomy including the tumor and preservation of the facial nerve using the modified Blair approach was performed. And satisfactory results have been obtained cosmetically and functionally.

Background/Objectives: Extracapsular dissection has the advantage of reducing complications by minimizing tissue loss of the parotid without intentionally exposing the facial nerve in patients with benign parotid tumor. However, there has been controversy over the surgical results. Thus, the surgical outcomes of extracapsular dissection for benign parotid tumor was compared to those of superficial parotidectomy. Materials & Methods: A retrospective chart review was conducted with 132 patients who received surgery for benign parotid tumor in our center from January 2014 to December 2018 retrospectively. Results: A total of 132 people were enrolled, with 62 people receiving extracapsular dissection, 38 people receiving partial superficial parotidectomy and 32 people receiving superficial parotidectomy. No significant difference was found between the three groups regarding complications such as facial nerve palsy, Frey's syndrome, or first bite syndrome. Operation time and hospital stay was significantly short in extracapsular dissection group. Conclusion: For well-selected cases, extracapsular dissection can be considered as an option for surgery of benign parotid tumor.

Introduction: A routine superficial parotidectomy with facial nerve dissection in parotid tumor surgery often results in facial dysfunction, Frey syndrome and defect in operation site. Formal facial nerve dissection has been a recommended procedure, because pleomorphic adenoma is a commonly recurrent tumor in case of inadequate surgical management, however it can not be always reasonable in aspect of postoperative sequelae. Patients and Methods: Through retrospective review of 245 cases parotidectomies and follow up for more than three years, clinicophathologic factors influencing to the selection of surgical procedure were considered to be age, sex, and preoperative pathology confirmed by preoperative MRI and FNA. Results: Five categories were established as follow for surgical decision in parotid tumor surgery. Category 1. Superficial lobe adenoma -- Superficial parotidectomy -- 124 Category 2. Deep lobe adenoma -- Deep parotidectomy -- 39 Category 3. Non pleomorphic adenoma -- Tumorectomy 1.5cm adenoma in young female -- Tumorectomy -- 25 Category 4. Recurrent multicentric tumor -- Parotidectomy+RT -- 9 Category 5. Parotid cancer; Parotidectomy + UND (RND) + RT -- 48 ; CORE (Composite Regional Ear Resection) -- 2 Conclusion: Surgical morbidity and recurrence rate could be minimized by individualizing the surgical procedure according to the category principle based on the clincopathologic features.

The lipoma is the neoplasm of mesenchymal origin. Although most lipomas occur on the trunk and the proximal portion of the extremities, lipomas of the oral and maxillofacial regions are relatively rare, approximately 13% of all cases. Lipomas have been found in all age, but usually found between 40 and 60 years of age. Clinically the lipoma is a painless, slowly growing, nearly always benign soft mass. The treatment of choice is a surgical excision, and the recurrence is rare. But the infiltrating lipoma originated from muscle has high recurrence rate. It has ill-defined border and little or no evidence of encapsulation. Histologically there is a consistent infiltration with dissociation of the surrounding muscle fiber. The infiltrating lipoma should be excised with surrounding normal muscle and tissue to prevent the recurrence. This case was a 57-year-old female with a painless swelling of the right cervical and parotid areas which was diagnosed as large infiltrating lipoma by clinical examination and radiographic findings. The patient was treated by surgical excision and showed good functional and esthetic results. Histologically the tumor was diagnosed as infiltrating lipoma with no evidence of malignancy.
