Epidermal cyst in the floor of mouth is relatively rare disease. Patients usually present soft and non-tender mass at the midline of mouth floor. Careful history taking and imaging study are needed for the diagnosis and surgical excision is the choice of treatment. We report a case of huge epidermal cyst located in the floor of mouth mimicking plunging ranula, which was successfully removed by transoral surgical excision without any complication. It was diagnosed as an epidermal cyst by pathologic examination.

The sialolithiasis is one of the most common disease that is found in the submandibular gland and they can be usually observed in the extra glandular area. As the lumen of Wharton's duct is larger and more expandable than that of Stensen's duct, the symptom of them is initially painless. Obstruction of salivary secretion by a sialolith can result in sudden swelling and pain, as well as infection of the gland. It can be observed with clinical exam and the scintigraphy. After removal of sialoliths, the majority of them can get the recovery of function. Our department performed the transoral sialolithotomy. One of three cases was recurred sialolithiasis with sialadenitis and was performed by the re-sialolithotomy and extraoral sialoadenectomy.

The cure rates for early stage laryngeal cancer are similar between laser cordectomy and radiation therapy. As well as the survival outcome, one of the main measures of success in treatment of early laryngeal cancer is voice outcome. Many studies have demonstrated that laser cordectomy and radiation therapy to be equivalent with regard to vocal outcome, whereas others favor radiation. Although such as somewhat disadvantages of voice outcome, laser cordectomy still remains a valid option. Since the patients who treated with laser may benefit from additional phonosurgery to improve postoperative vocal outcome. In this article, we reviewed the techniques of phonosurgery which can be used for laryngeal reconstruction after laser cordectomy. The indications for using each technique are discussed, with particular attention paid to functional outcomes following these reconstructive efforts.

Neurilemmoma is a relatively rare benign tumor which may be derived from nerve sheath of the peripheral, sympathetic and cranial nerve except the optic nerve and olfactory nerve. And it is a characteristically solitary and well-encapsulated mass. About 25% of neurilemmoma occurs in the head and neck region and the acoustic nerve is most frequently involved, but neurilemmoma of the larynx is rare. Recently, we experienced a case of neurilemmoma occurred in the right aryepiglottic fold of the larynx. The tumor was successfully removed by transoral approach under direct laryngoscope. So we report this case with literature review.

The zygoma is protruded on both sides of the midface and plays an important part in determining the impression of face. There are much different esthetic consideration of zygomatic prominence between the oriental and western. Because slight prominent zygoma is thought to be esthetic in the western, there has been done many augmentation therapy. But, in the oriental, prominent zygoma, especially in the female, is thought to be aggresive and manlike image, there has been done many zygoma reduction therapy. There are two methods to reduce the prominent zygoma, one is shaving method and the other is zygoma repositioning with ostectomy. The approach to zygoma and zygomatic arch without surgical morbidity is very difficult, so this problem has been difficult subject to oral & maxillofacial surgeon in a long period. We report the treatment case of facial asymmetry with the unilateral zygoma reduction & genioplasty using only intraoral approach with the retrospective study.

This is a report of two rare cases, that authors have experienced, one being four sialoliths within a wharton's duct, which is a relatively frequent site of sialolith, and the other a multiple occurrance of 16 sialoliths at the orifice of stensen's duct, which has very low frequency of sialolith occurance. Both pathosis were removed using transoral sialolithotomy.

Craniovertebral junction (CVJ) tuberculosis is a rare disease, and potentially fatal due to the risk of atlantoaxial dislocation. The disease usually accompanies a retropharyngeal cold abscess, which can cause subsequential otolaryngologic symptoms such asdysphagia, odynophagia, or airway obstruction. Such a patient must be handled with great care to avoid a disaster. The disease is diagnosed with microbiological or other laboratory tests on the pus collected through puncture and aspiration, which will need otolaryngologic skills. For treatment, otolaryngologists play an important role by doing incision and drainage of the retropharyngeal abscess, or by attending the transoral vertebra surgery as partners with spine surgeons who will manage the CVJ lesions and ensure the craniocervical stability.

A-50-year-old male patient presented with complaint of tenderness on the left malar area after traffic accident. Our first impression on him was zygomatic fracture, we did radiologic work-up and physical examination on him. But, on the computed tomography scan, there was no fracture or discontinuity on his facial bone. The computed tomography scan was revealed a 4-cm long foreign body in left maxillary sinus with a large amount of fluid collection. After thorough history taking from him, we reveal the patient had a history of trauma 30 years back on the left zygomatic area with a chopstick. The foreign body was removed via transoral approach with the endoscopic assist. There was no complication after operation.

We report five patients treated for esophageal fibrovascular polyps using a minimally invasive technique. Esophageal fibrovascular polyps are benign pedunculated submucosal tumors of considerable size. The treated polyps size ranged from 1.5 to 13 cm. The polyps were removed by relocation to the oral cavity under endoscopic control. No perioperative complications occurred after the treatment. The follow-up of patients after surgery was 9-89 months, with no evidence of polyp recurrence. Thus, the described treatment is safe but requires experience with endoscopy as well as esophageal 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.
