ABSTRACT
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.

ABSTRACT
Squamous cell carcinoma of the buccal mucosa has an aggressive nature, as it grows rapidly and penetrates well with a high recurrence rate. If cancers originating from the buccal mucosa invade adjacent anatomical structures, surgical tumor resection becomes more challenging, thus raising specific considerations for reconstruction relative to the extent of resection. The present case describes the surgical management of a 58-year-old man who presented with persistent ulceration of the mucosal membrane and a mouth-opening limitation of 11 mm. Diagnostic imaging revealed a buccal mucosa tumor that had invaded the retroantral space upward with involvement of the anterior border of the masseter muscle by the lateral part of the tumor. In this report, we present the surgical approach we used to access the masticator space behind the maxillary sinus and discuss how to manage possible damage to Stensen's duct during resection of buccal mucosa tumors.

BACKGROUND: When using the anterior approach for performing superficial parotidectomy, the first thing to do is to find the buccal branch of the facial nerve and the parotid duct. The buccal branch usually runs transversely with the parotid duct from the anterior border of the parotid gland. We wanted to check the relationship between the two structures during the operation and to get clinically helpful information. METHODS: Twelve patients with parotid mass were treated with superficial parotidectomy between May 2012 and August 2012. The outline of superficial and deep lobes of the parotid gland, parotid duct, and the buccal branch of the facial nerve were drawn on the transparent film by tracing the structures intraoperatively. RESULTS: In 7 (58.3%) of 12 cases, the buccal branch of the facial nerve was located more caudally than the parotid duct at the anterior border of the superficial lobe of the parotid gland. In 3 cases (25%), the buccal branch was located more cephalically than the parotid duct. The mean distance between two structures were 2.54+/-1.48 mm. In 11 cases, the parotid duct was located deeper than the buccal branch. CONCLUSION: The buccal branch of the facial nerve tends to be located more caudally than parotid duct and runs more superficially than parotid duct in all cases. We identified the relationship between the parotid duct and the buccal branch of the facial nerve during the operations on living subjects, not from the cadavers, so it would be a clinically helpful study which supplied more accurate anatomical information.

In this report, we introduce a case of surgical treatment for Stensen's duct stone with ultrasonography. A 49-year-old female patient presented with postprandial swelling in the right infraauricular lesion. Upon confirming the swelling as the Stensen's duct stone on the computed tomography scan, the sialolith was surgically removed using the transcutaneous procedure. Using ultrasonography, we found the exact location of the stone and removed it without any facial nerve injury. The case clearly demonstrated that the Stensen's duct stone canbe removed more easily and safely with ultrasonography.

It is important to both recognize parotid duct injuries and immediately repair them to prevent complications that accompany these injuries. Although there have been some reports of successful conservative treatments of the parotid duct injury, many authors recommend early surgical repair of the parotid duct and, when possible, primary anastomosis as the best treatment. Sialography is very useful for the diagnosis of parotid duct injury and can also support the information of parotid duct system. We present three cases of successful treatment of parotid duct injury with surgical repair. Also, we discuss about the effectiveness of surgical repair of parotid duct injury and how to assess it preoperatively.

The parotid is the largest salivary gland in humans producing an essentially serous secretion, which normally reaches the oral cavity through a sole duct (the parotid duct) after the latter making its way through the buccinator muscle to reach the mucosa lining the mouth at the level of the cheek. The present study reports on a rare case of double parotid duct found during the dissection the right side of the face of a cadaver of a 46-year-old male individual. The superior (Dl) and inferior (D2) ducts were 26.49 mm and 37.25 mm long, respectively. Based on the diameter of both ducts (Dl and D2) taken in the posterior (3.05 mm and 2.84 mm, respectively) and mid (2.84 mm and 2.68 mm, respectively) thirds, as well as on the histological findings, both ducts were considered to be main parotid ducts. These two ducts merged at the level of the anterior third forming one sole opening into the oral cavity. The data hereby reported are relevant to the various clinical and surgical procedures involving the parotid gland.
La parótida es la glándula salival más grande presente en el hombre y su producto de secreción, básicamente seroso, es normalmente dirigido hasta la cavidad oral, a través de un único canal parotídeo que, luego de perforar el músculo buccinador, desemboca en la mucosa de la mejilla. Este trabajo muestra un caso raro de doble canal parotídeo hallado durante la diseccción de un cadáver de sexo masculino, de 46 años de edad, en el lado derecho del rostro. Los canales superior (DI) e inferior (D2), presentaron una longitud de 26,49 mm y 37,25 mm, respectivamente. En base a los diámetros presentados por los canales en los tercios posterior (DI 3,05mm; D2 2,84 mm) y medio (DI 2,84mm; D2 2,68 mm) y de acuerdo con los hallazgos histológicos, ambos fueron considerados principales. En el tercio más anterior los canales se fusionaron, presentando una única apertura en la cavidad oral. Las informaciones presentadas en este documento son relevantes para diferentes procedimientos clínicos y quirúrgicos que tengan relación con la glándula parótida.

Sialectasis of Stensen's duct is a rare disease that is characterized by abnormal dilatation of the duct. The underlying pathology in this condition is obscure, but ductal dilation most commonly occurs as a consequence of ductal stenosis or narrowing. In this report, a rare case of sialectasis of Stensen's duct confirmed by radiologic study is presented with a review of the literature.

Stensen's duct is located at the anterior border of the parotid gland below the zygomatic arch. It crosses the area between the masseter muscle and buccal fat pad, opening opposite to the second upper molar teeth. Because of such anatomical association by the Stensen's duct, we should search for any injuries on the Stensen's duct when there is deep facial laceration. This paper reports on a case of parotid sialocele which was caused by laceration of Stensen's duct. For treamtemnt, we made an internal fistula to the oral cavity in order to drain the sialocele
