Patients with cleft lip and palate (CLP) must undergo corrective surgeries during infancy and early childhood. Many patients with CLP undergo orthognathic surgery during their childhood for correction of skeletal asymmetries or pharyngoplasty with a pharyngeal flap to improve the quality of speech and velopharyngeal function. During orthognathic surgeries, nasotracheal intubation is performed under general anesthesia. In our case report, the patient had undergone palatoplasty and pharygoplasty previously. During the orthognathic surgery, a flexible fiberoptic bronchoscope-guided nasotracheal tube was inserted through the pharyngeal flap ostium; however, active bleeding occurred in the nasopharynx. Bleeding occurred because the flap was torn. After achieving hemostasis, the surgery was completed successfully. Thus, if a patient may show the potential for velopharyngeal port obstruction, nasotracheal intubation should be performed with utmost care.

The partial A-V canal defect consist of ostium primum type atrial septal defect with a cleft mitral anterior leaflet. The clinical findings depend upon the site and size of the left-to-right shunt, the degree of A-V valvular regurgitation, and the degree of resultant pulmonary artery hypertension. We experienced 3 cases of similar condition. The data were as follow: 1. Chest P-A showed increased pulmonary vascularity and moderate cardiomegaly with left atrial enlargement. 2. E.K.G. showed left axis deviation, left atrial enlargement, and left ventricular hypertrophy. 3. Right heart catheterization showed significant 02 step up of SVC-RA and left-to-right shunt. 4. Left ventriculogram showed mitral regurgitation and filling of both atrium. Operative findings were as follow: 1. Primum type atrial septal defect [2x2 cm]. 2. Cleft in the anterior leaflet of the mitral vave. 3. No evidence of ventricular septal defect and tricuspid anomaly. Through a right atriotomy with moderate hypothermia, the mitral cleft was approximated with interrupted sutures. The interatrial communication was closed by a patch of Dacron/pericardium. The patch was attached to junction of the mitral and tricuspid valves along the crest of the ventricular septum using interrupted sutures and the other site using continuous sutures. Postoperative course was uneventful and discharged in good general condition except postoperative bleeding in case 3.

Mitral valve disease is the most common disease of the acquired heart diseases, and atrial septal defect is also one of common congenital heart diseases. Coexistence of these two lesions is rare, but of great hemodynamic interest. Among 443 cases with mitral valve disease and 90 cases with atrial septal defect experienced in the Department of Thoracic Surgery, Seoul National University Hospital, there were 6 cases with atrial septal defect complicated by mitral valve disease. 1. Of the 6 patients, four were female and two were male. The age was ranged from 18 to 46. 2. Atrial septal defect was ostium secundum type in all cases, and the mitral valvular lesions were regurgitation in four and stenosis in two. Type II ventricular septal defect was also combined in one of the cases. 3. The atrial septal defect was corrected by, primary closure and the mitral valve was replaced with the prosthetic or bioprosthetic valve in all cases. The combined ventricular septal defect was closed using Teflon felt patch. 4. The operative result was good except in one who was expired of bacterial endocarditis 4 months after hospital discharge.

We experienced a female patient with intramural hematoma of the aorta. This patient had a severe anterior chest pain radiating to interscapular area with choking sensation. CT revealed a intramural hematoma of the thoracic aorta and a part of the abdominal aorta but there was no evidence of intimal tearing. We did the eme gency operation under hypothermic circulatory arrest and retrograde cerebral perfusion. Ascending aorta was replaced and coronary artery bypass graft was done because of intimal tearing of the ostium of right coronary artery. She was discharged without any significant complication. We reported this case with consideration about necessity of emergency operation for intramural hematoma of the thoracic aorta.

A 60-year-old man visited the outpatient clinic due to one month of recurrent exertional chest pain. Eleven years earlier he had undergone off-pump coronary artery bypass grafting using bilateral internal thoracic artery (ITA) Y-composite grafts based on the left ITA. Preoperative coronary angiography showed patent distal graft anastomoses and visualized the left ITA retrogradely. The arch aortography revealed near-total occlusion of the left subclavian artery at the level of the ostium. The patient underwent left carotid-to-subclavian artery bypass grafting using a 6 mm vascular conduit. Postoperative computed tomographic angiography revealed a patent bypass conduit between the left common carotid artery and left subclavian artery. The patient was discharged on postoperative day 4 with no symptoms or signs of myocardial ischemia.

Tracheal diverticulum is relatively rare. It results from congenital or acquired weakness of the tracheal wall. Most cases are asymptomatic, but when symptoms are present, they are usually nonspecific. A 54-year-old man complained of sputum lasting for several months. Chest computed tomography showed an air-containing cystic structure in the trachea. Fiberoptic bronchoscopy demonstrated ostium arising from the right posterolateral wall at the trachea. Reported herein is a case of eosinophilic bronchitis associated with tracheal diverticulum.

Supravalvular aortic stenosis is an uncommon, congenital narrowing of the ascending aorta which originates just distal to the level of the ostium of the coronary artery. We conducted a successful surgical treatment in a 39 year- old female patient with a congenital supravalvular aortic stenosis and aortic regurgitation who did not show signs of William's syndrome. After we performed an inverted Y-shaped aortotomy toward the noncoronary sinus and right coronary sinus, pantaloon shaped prosthetic patch(Vascutek, Ino, USA) was used to repair the narrowing sinotubular junction. The aortic valve was replaced concommittently using Sorin Bicarbon 19mm. Her postoperative course was uneventful. The patient discharged at 9th postoperative day in good health.

A mucocele is an epithelium-lined, mucus-filled cavity in the paranasal sinuses. Mucocele may develop due to scarring and obstruction of the sinus ostium caused by midface sinus trauma, such as orbital bone fracture or endoscopic sinus surgery. The authors report two cases of orbital mucocele as complications following midface sinus injury (endoscopic sinus surgery in one case, and orbital fracture repair in the other). In both cases, imaging studies showed a large orbital mucocele accompanied by bony erosion and orbital wall remodeling, compressing the ocular muscle. Using an open approach, the lesion was excised and marsupialized. The symptoms resolved, and the postoperative eyeball position was normal. Orbital mucocele may cause serious complications such as ocular symptoms, orbital cellulitis, osteomyelitis, and the formation of an abscess with the potential to invade the brain. Therefore, surgeons should consider the possibility of mucocele as a late complication of surgery and initiate an immediate work-up and surgical treatment if needed.

Maxillary implants are inserted in the upward direction, meaning that they oppose gravity, and achieving stable support is difficult if the alveolar bone facing the maxillary sinus is thin. Correspondingly, several sinus-lifting procedures conducted with or without bone graft materials have been used to place implants in the posterior area of the maxilla. Even with these procedures available, it has been reported that in about 5% of cases, complications occurred after implantation, including acute and chronic sinusitis, penetration of the sinus by the implant, implant dislocation, oroantral fistula formation, infection, bone graft dislocation, foreign-body reaction, Schneiderian membrane perforation, and ostium plugging by a dislodged bone graft. This review summarizes common maxillary sinus pathologies related to implants and suggests an appropriate management plan for patients requiring dental implantation.

Maxillary sinus hypoplasia (MSH) is an uncommon clinical disease that represents a persistent decrease in sinus volume, which results from centripetal reaction of the maxillary sinus walls. We present a unilateral MSH case of a 46-year-old male patient with a history of nasal obstruction and headache for 3 years. He had a history of Caldwell Luc operation (CLOP) 10 years ago, and no enophthalmos, hypoglobus or facial asymmetry. After confirming the right diagnosis of MSH, filled with bone in the computed tomography scan, hyperplastic bone was removed by the CLOP approach. The uncinate process and infundibular passage were found to be degenerated and ostium was also examined to be obstructed under endoscopic confirmation. MSH can be mistaken for chronic maxillary sinusitis because of the plain x-ray appearance, so the aggravated state of MSH can be the result of surgeon's misjudgment. With additional literature reviews, this rare experience is first introduced in our Korean oral and maxillofacial surgery field.
