Rehabilitation of a patient with a post radiotherapy trismus with an obturator and a maxillary denture using magnet attachments / 대한치과보철학회지

Construction of an obturator for rehabilitation of a patient who underwent a maxillectomy is vital. Routinely a constructed obturator includes denture portion. A patient who may present anatomical limitations due to surgical or radiotherapy complications often challenges the clinician. Purpose: This clinical report describes a patient with severe trismus after surgical resection and radiotherapy treatment of a tumor in the upper left maxilla. Conclusion: This report describes the concepts of using a rotational path insertion for an obturator and a separately constructed maxillary denture. The stability and retention of the obturator were obtained from anatomical features. Where as these were achieved through magnetic attachments and the remaining edentulous ridge to ensure esthetic and function of the prosthesis.

A Case of Nasopharyngeal Teratoma Showing Upper Airway Obstruction

Neoplasms of the nasophrynx are rare in neonates and infants. The most common nasopharyngeal tumor encountered in this age group is teratoma-neoplasm containing multiple heterotopic tissues. Four histologic types of nasopharyngeal teratoma occur-dermoid, teratoid, true teratoma, epignathiof which dermoid is most frequently seen. We have experienced a case of nasopharyngeal teratoma in a female neonate with signs and symptoms of upper airway obstruction. It was diagnosed by cervical. CT and confirmed as ture teratoma by histological examination. Nesopharyngeal teratoma was removed by contact Nd:YAG laser. In addition, we briefly reviewed the literature of neonatal nasopharyngeal teratoma.
