Chondrosarcoma is extremely rare in maxillofacial soft tissue. A case diagnosed as well-differentiated chon- drosarcoma in the left parotid region was reported. The clinic pathological features, diagnosis, treatment, and prognosis were discussed with the literature review.

Agenesis of the parotid gland is a rare disorder, usually discovered after the onset of secondary symptoms such as dry mouth, dental decay, and gingival infections. We describe a case of unilateral agenesis of the parotid gland in a 42-year-old male with non-tender swelling in the contralateral parotid region. For diagnosis,physical examination, USG and CT were performed.

Masses of the Parotid-Masseteric area can be caused by various different conditions, most commonly neoplasms of a benign nature. A rare cause for parotid tumors is the embryologic remnant of first branchial cleft cysts. A first branchial cleft cyst is an unusual clinical condition and is hard to be recognized. It is often misdiagnosed because its clinical feature is similar to what can be seen in other common diseases. So it may result in a diagnostic delay and insufficient and dangerous primary surgery. Definite surgical treatment of first branchial cleft cyst requires complete surgical excision, which usually necessitates identification and protection of the facial nerve and superficial parotidectomy. We report a case of first branchial cleft cyst that arose in parotid. We had a good aesthetic and functional result of surgical extirpation with sparing superficial parotid gland. There was no serious complication except temporary weakness of marginal mandibular branch of facial nerve.

Depression of facial contour after parotidectomy is still challenging to many of surgeons. A 68-year-old man presented with a 4-month history of a painless swelling in both parotid area. The mass was multiple and fixed at the parotid region. We conducted a parotid duct preserving bilateral superficial parotidectomy by one-stage operation to remove the multiple tumors. A lazy S incision was made in both preauricular area and the peripheral branches of the facial nerve were identified using surgical landmark. After dissecting the branches of the facial nerve and parotid duct, main parotid duct was preserved but only small fine ductules from the superficial lobe were ligated. Parotid gland was excised from its anterior aspect with about 1 cm of normal parotid tissue margin. The patient was followed up for 6 years to evaluate postoperative parotid gland function and the computed tomography (CT) was taken. Patient was satisfied with no significant complication such as sunken changes in facial contour, facial nerve function. As far as we know, it is the first study to compare long-term soft tissue contours of soft tissue of duct preserving superficial parotidectomy with duct sacrificing superficial parotidectomy by means of CT findings.

Pneumoparotid is a rare cause of parotid gland swelling, and is caused by retrograde air reflux from the oral cavity, into the parotid gland via Stensen's duct. Most patients complained of painless swelling in the parotid region. Herein, we report a rare case of pneumoparotid, incidentally diagnosed without symptoms on CT, for follow-up of parotid lymph node enlargement.

A sialo-cutaneous fistula is a communication between the skin and a salivary gland or duct discharging saliva. Trauma and iatrogenic complications are the most common causes of this condition. Treatments include aspiration, compression, and the administration of systemic anticholinergics; however, their effects are transient and unsatisfactory in most cases. We had a case of a patient who developed an iatrogenic sialo-cutaneous fistula after wide excision of squamous cell carcinoma in the parotid region that was not treated with conventional management, but instead completely resolved with the injection of botulinum toxin. Based on our experience, we recommend the injection of botulinum toxin into the salivary glands, especially the parotid gland, as a conservative treatment option for sialo-cutaneous fistula.

Kimura disease(KD) is a chronic inflammatory disorder of unknown etiology and results from an abnormal proliferation of lymphoid follicles and vascular endothelium and rarely has been reported in Korea. Clinical findings of Kimura disease include solitary or multiple, firm, subcutaneous nodules, which usually are located on the head or neck but parotid region is the most common site. The clinical course of the disease is chronic, with lesions frequently persisting or recurring despite treatment. The prognosis for KD is good, with no potential for malignant transformation. Our case is a 45-years-old man who had huge mass on left cheek which had slowly grown since about 10 years before. We planned to perform superficial parotidectomy but the mass was poorly demarcated due to extensive fibrosis and adhesion and had easy bleeding tendency. After frozen biopsy, we performed tumor debulking operation followed by cyclosporin therapy by the dose of 2.5 mg/Kg/day. The lesion was almostly cleared successfully after 3 months later. We report important aspects of clinical findings, histologic features, and therapeutic options of the rare case of KD with review of the previous articles.

Congenital absence of the major salivary glands, especially of the parotid gland, is a rare disorder whose etiopathogenesis is poorly understood. Aplasia of the parotid glands may be unilateral or bilateral and may occur alone or in association with the absence of other salivary glands or with other developmental anomalies of the first branchial arch, such as hypoplasia or aplasia of the lacrimal glands, hemifacial microsomia, mandibulofacial dysostoses, and multiple congenital anomalies. Various degree of xerostomia and dental caries with early loss of teeth may occur due to decreased salivary production. The authors experienced a case of unilateral parotid aplasia in a 22-year old female who had painless swelling in the right parotid region. We present this case with review of literature.

Lateral thoracic flap is a free flap for the reconstruction of soft tissue defects and has been previously used in oral and maxillofacial surgeries. We reported a case involving a huge soft tissue defect on the parotid region caused by the resection of parotid epithelial myoepithelial carcinoma. We discussed the anatomy and application of the lateral thoracic flap.

Extracranial meningioma arises from ectopic arachinoidal cells and common sites of these tumors are orbit, scalp, upper respiratory tract, and parotid region. Extracranial meningioma of paranasal sinus is rare. This tumor shows various histological findings and is diagnosed by combination of CT, MRI, angiography, and pathological findings. Treatment of choice is surgical excision. Recently, we experienced a case of meningioma involving ethmoid sinus which was completely excised by endoscopic sinus surgery. So, we report our experience of ectopic meningioma of ethmoid sinus with a brief review of the literature.
