Management of dental complications in a child with rhabdomyosarcoma.

Radiotherapy treatment options can cause adverse dental sequelae, including xerostomia, dental radiation caries, abnormal tooth development, and osteoradionecrosis (ORN). Hyperbaric oxygen (HBO) therapy can be used prophylactically or therapeutically to treat or reduce the risk of ORN. The purpose of this paper was to describe a case involving a 5-year-old male with rhabdomyosarcoma of the left temporal fossa and a history of radiation therapy who presented with gross radiation caries and xerostomia. Full-mouth extractions of all primary teeth were performed under general anesthesia, with the patient receiving HBO therapy before and after the surgery. The child was monitored postoperatively, and healing occurred with minimal post-operative complications. Based on his results, it can be concluded that hyperbaric oxygen therapy is an effective supplement to consider when treating children who have undergone radiation therapy and require dental care.

Maxillary removal and reinsertion: a favorable approach for extensive anterior cranial base tumors.

OBJECTIVE: To analyze the long-term results and the complications related to an expanded series of maxillary removal and reinsertion (MRRI) with 18-year surgical experience. STUDY DESIGN: Case series with chart review of the MRRI patients in the last 18 years. SETTING: The Ohio State University Comprehensive Cancer Center, James Cancer Hospital and Solove Research Institute. SUBJECTS AND METHODS: Seventy-eight patients who underwent MRRI from February 1990 through February 2007. The median age was 51 years (range 11-77 yrs). Sixty-two (80%) patients had malignant lesions. RESULTS: MRRI has been successfully completed in all 78 patients, with no intraoperative mortality. The most commonly encountered malignant neoplasm was squamous cell cancer (40.3%), followed by esthesioneuroblastoma (24.1%), adenoid cystic cancer (8%), and other neoplasms (27.4%). The most commonly encountered postoperative complication was diplopia, which has persisted in five (6.4%) patients in the short-term and in three (4%) patients in the long-term follow-up. Nasal asymmetry was the most common long-term complication (17.9%), followed by plate-associated problems (10.2%) and midface asymmetry (10.2%). Overall five-year survival for the patients with squamous cell carcinoma was 62 percent. CONCLUSION: MRRI is a favorable surgical technique for the treatment of anterior cranial base (ACB) tumors in adults and even in children. It improves operative morbidity by preserving both function and form of the maxillary region and gives excellent exposure to ACB.
