악안면 부위의 선천적 결손이나 외상성 손실, 종양의 외과적 절제 등에 의한 악골의 결손은 환자에게 저작 장애, 연하 장애 등의 기능적 문제와 발음장애 및 심미적 장애를 초래하게 된다. 이러한 장애를 줄여주고 손상된 조직과 기능을 회복시켜주기 위해 많은 경우 보철적인 수복을 필요로 하게 된다. 상악골에 결손부가 생긴 경우 음식물과 액체가 비강으로 새어나가고 이 결손부로 공기가 누출되어 과비음이 발생한다. 이런 경우에 구개 폐쇄 장치가 사용되는데, 이 장치는 상악의 결손부를 채우고 구강과 상악동 또는 비강과의 개통부를 차단하여 심미성을 증진시키고 기능을 회복시킨다. 본 증례의 환자는 우측 상악동에 편평상피세포 암종이 발생하여 상악골 부분 절제술을 시행한 환자로 구개 폐쇄 장치를 제작하여 장착한 후, 발음과 연하 등의 기본적 기능이 회복되었고 안모의 심미성이 증가하였다.
Abstract
Congenital or traumatic loss on the oral and maxillary area or the loss of jaws due to the surgical excision of a tumor causes functional problems, such as masticatory and swallowing disorders, phonetic problems and psychological disorders in patients. In most cases, a prosthetic restoration is needed to resolve these problems and restore the damaged tissue and function. When loss occurs on the maxilla, foods and liquids leak into the nasal cavity, and a nasal sound can be heard due to air leakage into the removed area. In these cases, the palatal obturator can be used to improve the esthetic and functional aspects because it restores the removed area of the maxilla and closes the opened route between the oral cavity and maxillary sinus or nasal cavity. In this case report, a palatal obturator was applied to patients who had a hemimaxillectomy due to the occurrence of squamous cell carcinoma on the right maxillary area. Therefore, fundamental functions, such as phonetic and swallowing functions were restored, and the esthetic aspects of the facial profile were improved
