Sialolithiasis is relatively common disease of the salivary gland in the field of Oral & Maxillofacial surgery. Obstruction of salivary secretion by a sialolith can result in swelling and pain, as well as infection of the gland. The swelling is usually correlated to meals, when salivary secretion is enhanced. Sialolithiasis occurs mainly in the submandibular gland(92%) and to a lesser degree in the parotid gland(6%). The sublingual gland and the minor salivary gland are rarely affected(2%). This is a report of rare case, the authors have experienced, within the left sublingual gland and the minor salivary glands. It is multiple sialolithiasis(about 22 silaoliths) in the sublingual and the minor salivary glands which has very low incidence of sialolithiasis. The pathosis were removed using transoral sialolithotomy with sublingual sialadenectomy.

Background Median cleft lip is a rare anomaly consisting of a midline vertical cleft through the upper lip. It can also involve the premaxillary bone, the nasal septum, and the central nervous system. In our current report, we present the clinical features of 6 patients with a median cleft lip and their surgical management according to the accompanying anomalies. Methods From December 2010 to January 2014, 6 patients with a median cleft lip were reviewed. Five of these cases underwent surgical correction; alveolar bone grafting was performed in a patient with a median alveolar cleft. The surgical technique included inverted-U excision of the upper lip and repair of the orbicularis oris muscle. The mean follow-up period was 20.4 months (range, 7.4-44.0 months). Results The study patients presented various anomalous features. Five patients received surgical correction, 4 with repair of the median cleft lip, and one with iliac bone grafting for median alveolar cleft. A patient with basal sphenoethmoidal meningocele was managed with transoral endoscopic surgery for repair of the meningocele. Successful surgical repair was achieved in all cases with no postoperative complications. Conclusions Relatively mild forms of median cleft lip can be corrected with inverted-U excision with good aesthetic outcomes. In addition, there is a broad spectrum of clinical features and various anomalies, such as nasal deformity, alveolar cleft, and short upper frenulum, which require close evaluation. The timing of the operation should be decided considering the presence of other anomalies that can threaten patient survival.

Neurofibroma is characterized as a benign, slow growing neoplasm, originating from Schwann cells or fibroblast in peripheral nerve sheaths. It may appear as a solitary tumor or have multiple localizations in von Recklinghausen disease. They are commonly found in the gastrointestinal tract and laryngeal neurofibromas are extremely rare, accounting for only 0.03 to 0.1% of benign tumors of the larynx. The aryepiglottic fold and arytenoid are the common site of occurrence for laryngeal neurofibroma, because the branch of the superior laryngeal nerve is involved. We present a case of solitary plexiform neurofibroma arising from the laryngeal surface of epiglottis in a 55-year old female who found the lesion incidentally. We removed the tumor completely by transoral laser surgery and no recurrence was found after 7 months. The case of solitary neurofibroma arising from laryngeal surface of epiglottis has not been reported in Korea. We report this case regarding the diagnosis and treatment with review of literatures.

Intermaxillary fixation is routine procedure to oral and maxillofacial area in jaw bone fracture, surgical correction of jaw deformity, osseus reconstruction of jaw. After transoral surgery, accompanied by intermaxillary fixation, dysphagia or airway obstruction may be followed due to blood clot, vomitus, or laryngeal spasm resulting from irritation by blood or secretions. Lingual or pharyngeal edema is other contributing factors of airway obstruction. In addition, intermaxillary fixation itself may cause obstruction of airway. In this study, pulmonary function test and arterial blood gas analysis were evaluated before and after intermaxillary fixation in 30 patients suffered from mandibular fractures. Comparative analysis was performed by estimated values. The results were as followed. 1. The spirometric values of FEV1, FEV1/FVC and FEF25-75% without intermaxillary fixation were reduced from 97.57%, 85.1%, 98.3,% to 71.7%, 66.5%, 61.2% with intermaxillary fixation, indicating the presence of obstructive pulmonary impairment. 2. Spirometric value of MVV, as the most influencing value of sensitive to extrapulmonary factors, was changed from 84.5% to 46.48%. 3. After intermaxillary fixation, the spirometric value of FVC, as indicator of restrictive pattern of pulmonary function, was not reduced significantly as measured from 94.47% to 89.97%. 4. $O_2$ saturation of arterial blood gas analysis without intermaxillary fixation was 97.86%. While intermaxillary fixation, $O_2$ saturation was 97.47%. The results indicate that careful airway management is mandatory undergoing intermaxillary fixation of various oral and maxillofacial surgery.

Styloid process is a slender pointed bone of variable length, which project downward, forward, and slightly medialward from the posteroinferior portion of the tympanic part of the temporal bone. Embryologically, the styloid process is derived from Reichert's cartilage, a structure of second branchial arch origin. Most patients with elongated styloid process remain asymptomatic, but some patients complain pain and sensation of foreign body in the throat, dysphagia, dysphonia, referred otalgia. Recently, we have experienced a case of elongated styloid process in a fifty-nine year old man. He had been suffered from Rt. side sore throat, headache and pharyngeal discomfort during head movement. Through various X-ray examination, Xeroradiography, and palpation of tonsillar fossa, elongated styloid process on Rt. side was confirmed. Under the general anesthesia, it was successfully removed out via transoral approach technique, described by Eagle. The resected styloid process was 2.5cm in it's length and he was freed from the symptoms without further complication.

The development of office-based, unsedated transnasal esophagoscopy (TNE) has proven to be a major technological advance and with time and experience the application of this technology is becoming more widespread. TNE has allowed otolaryngologists to perform a variety of diagnostic and therapeutic procedures in the office setting. Studies consistently demonstrate that the image quality and diagnostic capability of TNE is equivalent to conventional esophagoscopy. The modern TNE endoscopes offer high quality optics, air-insufflation, and irrigation capability through a 2-mm working channel, and the ability to perform biopsies and select procedures. In general, the role of TNE in the head and neck patient is three-fold : to screen for synchronous and metachronous esophageal squamous cell carcinoma (ESCC) ; to differentiate post-treatment changes/symptoms from malignancy ; and to perform certain office-based procedures. TNE offers many specific advantages to the head and neck patient that are not afforded by conventional esophagoscopy. Because of surgical and postirradiation changes, many HNSCC patients have trismus or neck stiffness preventing completion of conventional transoral esophagoscopy. Perhaps most importantly, TNE provides enhanced patient safety, increased tolerability, better practice efficiency, and cost savings. For these reasons, TNE has become a particularly useful tool in the otolaryngologist's armamentarium.

Purpose: Fibrillar collagens like type I collagen, are the major constituent of the extracellular matrix and structural protein of bone. Also, it can be a scaffold for osteoblast migration. The purpose of this study is to estimate the effects of absorbable atelo-collagen sponge (Teruplug$^{(R)}$, Terumo biomaterials Co., Tokyo, Japan) insertion in tooth extraction sites on periodontal healing of the second molar, healing of the fractured mandibular bone and new bone formation of third molar socket after the extraction of the impacted third molar with mandibular angle fracture. Methods: In our study of six cases of mandibular angle fractures, all of them underwent the extraction of the third molar tooth & absorbable atelo-collagen sponge insertion in tooth extraction site. Three of them had a intraoral infection & oral opening to fracture site, two of the six had dental caries, and only one had reduction problem due to third molar position. Six consecutive patients with noncomminuted fractures of the mandibular angle were treated by open reduction and internal fixation using one noncompression miniplates and screws placed through a transoral incision. Results: All of the patients have showed good postoperative functions and have not experienced complications requiring second surgical intervention. There was well healing of the mandibular bone and the most new bone formation of third molar socket after the extraction of the impacted third molar with mandibular angle fracture. Conclusion: The results of this study suggest that absorbable atelo-collagen sponge is relatively favorable bone void filler with prevention of tissue collapse, food packing, and enhance periodontal healing. Thus, the use of atelo-collagen sponge and one noncompression miniplate seems to be relatively easy, safe, and effective for the treatment of fractures of the mandibular angle and third molar extraction.
