Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance, with FSOT being diagnosed mostly by computed tomography or intraoperative dye. Several options are available to surgeons when treating FSOT injury, and they need to be familiar with these options to take the proper treatment measures in order to follow the treatment principle for FSOT, which is a safe sinus, and to reduce complications. This paper aimed to examine the surrounding anatomy, diagnosis, and treatment of FSOT.

Mess removal, electrocoagulation, cryosurgery are conventional methods in the treatment of various oral mucosal diseases. However, there are several problems or complication during or after surgery using conventional tools. Recently, LASER gradually become useful tool in the surgery of oral mucosal diseases. Of the LASER, carbon dioxide-mediated LASER is widely used one. Carbon dioxide LASER has many advantages such as good bleeding control, decreased damage to adjacent tissue, decreased pain and swelling, reduced scar formation, even bacteriocidal effects. In this reports, the author describe pros and cons of LASER, especially focused on carbon dioxide, and shed light on the field of LASER application in treatment of various oral mucosal diseases.

Ranula is a mucocele caused by extravasation of the sublingual gland on the floor of the mouth. The most common presentation is a cystic mass in the floor of the mouth. A portion of the sublingual gland could herniate through the mylohyoid muscle, and its extravasated mucin can spread along this hiatus into submandibular and submental spaces and cause cervical swelling. This phenomenon is called plunging ranula. A variety of treatments for ranula has been suggested and include aspiration of cystic fluid, sclerotherapy, marsupialization, incision and drainage, ranula excision only, and excision of the sublingual gland with or without ranula. Those various treatments have shown diverse results. Most surgeons agree that removal of the sublingual gland is necessary in oral and plunging ranula. Four patients with ranula were investigated retrospectively, and treatment methods based on literature review were attempted.

A 12-year-old spayed female Cocker Spaniel was presented with vomiting, diarrhea, depression, and hyporexia of 3-day duration. Microscopic examination of the abdominal fluid from a dog showed basophilic, amorphous to fibrillar materials without bile pigments or crystals. Total bilirubin concentration of the fluid was 19 times higher than the serum bilirubin concentration and exploratory laparotomy revealed a ruptured gallbladder and mucoceles in the abdominal cavity. Rupture of gallbladder mucoceles may cause atypical bile peritonitis in which mucinous material is observed instead of bile pigment.

A 13-year-old female Poodle presented with gallbladder rupture caused by a mucocele and hypoperfusion. The animal had a thermal burn injury caused by a forced-air warming device used for hypothermia during surgery. This could be attributed to two causes. First, the forced-air warming device was used with direct hosing, without attachment to an air blanket, and the heat was concentrated in a single area. Second, perioperative peripheral hypoperfusion hampered heat dissipation and increased the susceptibility to a burn injury. These findings suggest that an air blanket should be used with a forced-air warming device according to the manufacturer's instructions. Furthermore, patients with peripheral hypoperfusion are at a higher risk of burn injuries and require close monitoring.

Minor salivary gland sialolithiasis (MSGS) is a not uncommon oral mucosal disease. Its clinical appearance may mimic a mucocyst or other benign submucosal overgrowth. Stasis of saliva, which accompanies MSGS, usually results in minor salivary gland inflammation, with a chronic sialadenitis appearance. MSGS typically is a painless lesion but can become painful when the salivary gland parenchyma or excretory duct becomes infected, with or without pus. However, misdiagnosis of this condition is rather common, as the clinical appearance is asymptomatic. The most common location is the upper lip, and MSGS affects males and females, with a slight predilection for males. The sialolith causing MSGS may be obvious during surgical excision, as in the case reported. In other cases, sialolith may be absent or fragmented. Differential diagnosis includes mucocele, swelling due to local irritation like fibroma and diapneusia, chronic abscess of the oral mucosa, and neoplasms either benign (lymphangioma, pleiomorphic adenoma) or malignant. Histopathological examination is needed to establish clinical diagnosis.

점액낭종은 타액선의 분비도관이 외상, 타석, 반흔조직등에 의해 폐쇄되거나 파열되어 점액이 조직내로 유출 및 저류되어 발생하는 가성의 낭종으로, 이 중 하마종은 구강저에서 발생하는 점액낭종에 사용하는 용어이다. 염증에 이환되지 않았다면 대부분이 무통의 양상을 나타내며 심부에 위치할수록 정상색조를 띄게된다. 점액낭종의 치료는 주로 재발을 방지하기 위하여 인접소타액선을 포함한 완전절제를 시행하며, 병소의 크기가 큰 경우 부분절제를 시행하기도 한다. 하마종의 치료는 조대술과 완전절제술이 있으며, 조대술은 찾은 재발을 일으키는 단점이 있으나 치료가 성공적으로 시행되었을 경우, 환자에게 타액선이 제거되는 불편감을 덜 할 수 있다. 본 증례에서는 하순과 구강저에 발생한 점액낭종과 하마종을 완전절제술과 조대술로 치료하고 그 경과를 관찰한 바 술 후 재발이 관찰되지 않았고, 정상기능을 회복하였다 향후 치료부위의 재발여부에 대한 계속적인 관찰이 필요하리라 생각되며, 하마종의 치료시 조대술이 적절히 이용되었을 때 환아의 불필요한 타액선 절제를 피할 수 있다고 사료된다. 또한 점액낭종의 치료시, 병력과 임상적 특징을 바탕으로 한 정확한 감별진단과 적절한 치료법의 선택이 중요하다는 결론을 얻었다.

Fractures of frontal sinus account for 5%-12% of all fractures of facial skeleton. Inadequately treated frontal sinus injuries may result in malposition of sinus structures, as well as subsequent distortion of the overlying soft tissue. Such inappropriate treatment can result in aesthetic complaints (contour deformity) as well as medical complications (recurrent sinusitis, mucocele or mucopyocele, osteomyelitis of the frontal bone, meningitis, encephalitis, brain abscess or thrombosis of the cavernous sinus) with potentially fatal outcomes. Frontal contour deformity warrants surgical intervention. Although deformities should be corrected by the deficiency in tissue type, skin and soft tissue correction is considered better choice than bone surgery because of minimal invasiveness. Development of infection in the postoperative period requires all secondary operations to be delayed, pending the resolution of infectious symptoms. The anterior cranial fossa must be isolated from the nasal cavity to prevent infectious complications. Because most of the complications are related to infection, frontal sinus fractures require extensive surgical debridement and adequate restructuring of the anatomy. The authors suggest surgeons to be familiar with various methods of treatment available in the prevention and management of complications following frontal sinus fractures, which is helpful in making the proper decision for secondary frontal sinus fracture surgery.

Solitary extramedullary plasmacytomas are isolated plasma cell tumors of soft tissue that typically do not metastasize. They are rare and account for 4% of all plasma cell tumors. To our knowledge, only 14 cases of solitary extramedullary plasmacytomas in the sphenoid sinus have been reported. A 32-year-old man presented to our department with complaint of ocular pain in the right eyeball and diplopia. Physical and neurological examinations revealed intact and prompt direct and indirect light reflexes in both pupils and limitation of extraocular muscle movement seen with the lateral gaze of the right eyeball. Magnetic resonance imaging suggested the presence of mucocele or mycetoma, therefore surgical resection was performed with endoscopic endonasal transsphenoidal approach. Histopathology was consistent with plasmacytoma. Systemic work-up did not show any evidence of metastasis and the sphenoid sinus was the sole tumor site, and therefore the diagnosis of solitary extramedullary plasmacytoma was confirmed. We report a rare case of solitary extramedullary plasmacytoma in the sphenoid sinus with successful treatment using the endoscopic endonasal transsphenoidal resection and adjuvant radiotherapy.
