  • Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity.

  • Sarcomatoid carcinoma is a rare and occurs mainly in the upper aerodigestive tract such as the oral cavity, esophagus and vocal cords. It is a unique variant of squamous cell carcinoma. We report the case of a patient with spindle cell squamous cell carcinoma involving the mandible. At initial examination, overlying mucosa of that lesion was normal appearance. One week later, that lesion showed ulcerative and bloody change and rapid growth in size. This case showed unpredictable rapid growth although rapid growth in size was suspected of undergoing malignancy.

  • Vinyl acetate has been widely used for the manufacture of polyvinyl alcohol emulsion, which is primary ingredient of adhesive, paints, textile, paperboard coatings, etc. Since these products are plentiful and frequently used around us, workers and consumers are at health risk. International Agency for Research on Cancer(IARC) classified vinyl acetate as group 2B(possibly carcinogenic to humans). Among the organs targeted, the oral cavity is the most vulnerable organ affected by the carcinogenic effects of vinyl acetate. Since the origin of most of oral cancer is derived from the epithelial cells, it is important to understand the carcinogenic potential of vinyl acetate in human epithelial cells. Thus, the present study has attempted to utilize the immortalized human epithelial cell model to assess the carcinogenic potency of this chemical and to understand the underlying mechanisms.

  • The salivary duct cyst is a rare disease and usually found in the parotid gland. A 55-years-old man presented swelling in the left buccal area and pathological diagnosis was a salivary duct cyst. Though its recurrence has been reported rare, the presented case showed recurrent swelling after enucleation. The recurrent lesion was successfully treated by incision and drain insertion.

  • Pilomatricoma, calcifying epithelioma of Malherbe, is a benign skin neoplasm of hair matrix origin that is typically occurred in the head and neck region. It usually presents as a superficial, firm, solitary, slow-growing, and painless mass of less than 3 cm in diameter and most often occurs in young age under 20 years. The tumor does not express an aggressive behavior and surgical excision is the treatment of choice. The purpose of this article is to present a case of pilomatricoma of the preauricular region and to review the literature regarding pilomatricomas of the head and neck region.

  • Last week, after our receiving online journal regarding Journal of the Korean Association of Oral and Maxillofacial Surgeons, we found a recently published original article by Alawode et al., entitled "A comparative study of immediate wound healing complications following cleft lip repair using either absorbable or non-absorbable skin sutures". Although this clinical article was well written and provided a great deal of information regarding the suture materials in the cleft lip repair, I would like to add a few additional comments based on the importance of skin suture during cheiloplasties in the primary cleft lip or secondary revision patients with representative figures.

  • Objectives: This study investigated the types and antibiotic sensitivity of bacteria in odontogenic abscesses. Materials and Methods: Pus specimens from 1,772 patients were collected from affected areas during incision and drainage, and bacterial cultures and antibiotic sensitivity tests were performed. The number of antibiotic-resistant bacteria was analyzed relative to the total number of bacteria that were tested for antibiotic susceptibility. Results: Bacterial cultures from 1,772 patients showed a total of 2,489 bacterial species, 2,101 gram-positive and 388 gram-negative. For penicillin G susceptibility tests, 2 out of 31 Staphylococcus aureus strains tested showed sensitivity and 29 showed resistance. For ampicillin susceptibility tests, all 11 S. aureus strains tested showed resistance. In ampicillin susceptibility tests, 46 out of 50 Klebsiella pneumoniae subsp. pneumoniae strains tested showed resistance. Conclusion: When treating odontogenic maxillofacial abscesses, it is appropriate to use antibiotics other than penicillin G and ampicillin as the first-line treatment.

  • Maxillary sinus floor augmentation (MSFA) is an essential procedure for implant installation in the posterior maxillary area with vertical alveolar bone deficiency. For the past several decades, MSFA has been refined in terms of surgical methods along with technical progress, accumulation of clinical studies, and development of graft materials and surgical instruments. Although some complications in MSFA are inevitable in clinical situations, management of those complications in MSFA has been well established thanks to many clinicians and researchers. Nevertheless, some rare complications may arise and can result in fatal results. Therefore, clinicians should be well aware of such rare situations and complications associated with MSFA. In this review, the authors present several rare complications regarding MSFA, along with corresponding management strategies through a thorough review of the literature.

  • 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.
