  • Pleomorphic adenoma (PA) is a benign tumor which usually originates from major and minor salivary glands. This tumor arising outside submandibular gland (SMG) is extremely rare. To author's knowledge, only four cases have been reported so far in English literature. Its pathogenesis is still unclear, but it can be explained by embryologic theory of major salivary gland. A 68-year-old man with an incidental mass on left upper lateral neck visited to our clinic. The radiologic findings showed well-margined round mass outside left SMG. The excisional biopsy revealed a pleomorphic adenoma. We report the rare and unique case with a brief literature review.

  • The submandibular gland is the second largest major salivary gland, which secretes 40% of the total daily saliva. Owing to its anatomic characteristics as well as the high viscosity and basicity of the saliva, sialolithiasis is found most commonly in the submandibular gland. Sialolithiasis that cannot be treated by conservative treatment is conventionally removed by an excision of the submandibular gland. Generally, an excision of the submandibular gland is performed via an extra-oral approach but the disadvantages of this treatment include a risk of injuring the facial nerve and scar formation. Case reports have revealed an even less invasive intraoral surgical technique for the removal of sialolith that does not affect the submandibular gland function. The functional recovery of the gland, complications and recurrence rates after surgery with this conservative intraoral procedure were all successful. We report 5 patients from the department of Oral and Maxillofacial Surgery at Dental Hospital, Yonsei University, who had undergone a resection of the sialolith though the intraoral approach with successful results.

  • 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. As increasing their size, the sign and symptom are pain and sudden enlargement of 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 and the extraoral sialoadenectomy for three patients of sialolithiasis and all of them showed no complication after operation.

  • 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.

  • 치과 방사선검사에 있어 두부 내의 흡수선량에 관한 평가를 하고자 인체모형팬텀 내부의 뇌하수체와 안구, 상악동, 악하선, 갑상선, 식도에 유리형광소자를 삽입하고 X-선을 조사하였다. 사용된 장치로는 Kodak 2200, Kodak 8000C dental radiographic systems과 computed tomography(Lightspeed VCT)이고 촬영조건은 임상에서 사용하는 인자와 동일하게 설정하였다. 이때 구내 X-선 검사의 경우 흡수선량은 0.02~2.47cGy로 가장 높게 측정된 곳은 상악 대구치 촬영 시 2.47cGy인 갑상선이었고 가장 낮은 곳은 하악 전치부 촬영에서 0.02cGy인 악하선이었다. 그리고 구외 X-선 검사의 경우 흡수선량은 세파로에서 0.36~3.44cGy, 파노라마에서 0.14~12.82cGy, 전산화단층촬영에서 8.17~253.63cGy 가장 높게 측정된 곳은 상악 CT 촬영 시 253.63cGy인 악하선이었고 가장 낮은 곳은 파노라마 촬영에서 0.14cGy인 안구이었다. 구외 X-선 검사가 구내 X-선 검사 보다 많은 흡수선량이 측정되었다. 특히 CT를 이용한 검사에서는 구내 촬영보다 100배 이상 높게 측정되었다. 따라서 구외 X-선 검사에 있어서 가이드라인을 제시하여야 하며 방사선에 의한 흡수선량을 줄이기 위한 노력이 요구된다.
