The Leicester radiotherapy bite block: an aid to head and neck radiotherapy.

We describe the construction of a custom-made bite block to be used during external beam radiotherapy to the oral cavity. The bite block is made with standard maxillofacial prosthetic techniques and materials. The design allows accurate and reproducible positioning of the perioral tissues to aid planning of radiotherapy and treatment. The compressibility of this device improves comfort for the patient, while it is in use.

Ameloblastoma--a diagnostic problem.

A 50-year-old female was referred by her dental practitioner. She had a periapical radiolucency associated with the lower right second premolar tooth. The tooth was root treated and subsequently apicected. Tissue curetted at the time of surgery was shown to be a solid ameloblastoma which was managed initially by marginal excision. Histopathological examination of the resection specimen demonstrated tumour at the inferior margin. A segmental resection of the mandible with an immediate reconstruction using a free tissue transfer of the iliac crest was therefore performed. The case shows the need for vigilance in dealing with periapical pathology and underlines the importance of sending all tissue specimens for histopathological analysis.

Delays in the referral and treatment of oral squamous cell carcinoma.

OBJECTIVE: To investigate the delays in referral and treatment of patients with oral cancer. DESIGN: A retrospective study. SETTING: District General Hospital Maxillofacial Unit (MFU). SUBJECTS: 100 consecutive patients with invasive squamous cell carcinoma of the oral cavity referred to Rotherham District General Hospital Maxillofacial Unit (RDGH MFU) between 15th March 1993 and 16th January 1998. METHOD: Information collected at the time of referral and treatment was examined retrospectively. RESULTS: In the patients studied 72% were male, mean age 61.2 years (sd = 11.2, range 37 to 88) and 28% female, mean age 65.6 years (sd = 16.7, range 29 to 90). The majority of referrals were from medical practitioners (56%) and most of the remainder being referred by dental practitioners (36%). The patient delay was found to be the most significant with only 39% presenting within 4 weeks, 29% delayed more than 3 months. There was no statistical correlation between T-stage, alcohol or cigarette use and the patient delay in presentation. Having presented to a medical or dental practitioner 69% were referred within 1 week. There were no significant differences between the T-stages presenting to either medical or dental practitioners or in their delay in referral for each stage. There was no significant difference in age or sex distribution between the populations presenting to general medical or general dental practitioners. General medical practitioners were more likely to refer a patient urgently. Patients referred directly to the MFU were seen quickly but those referred via an indirect route were delayed. 95% of patients were treated within 6 weeks of first consultation. CONCLUSION: The majority of practitioners refer patients with oral cancer within 1 week. The most significant delay is that caused by the patient. Some practitioners referred patients to inappropriate specialties, leading to indirect referrals. This results in additional delay in the referral and treatment pathway. Education of the public and primary health care workers should continue. Opportunistic screening of the oral mucosa should be part of the dental check up, with possible targeting of patients at greatest risk, particularly heavy drinkers and smokers.

Traumatic medial malleolar fracture of a fibula flap donor leg.

A 50-year-old male presented with a T4 N0 squamous cell carcinoma of the floor of the mouth and alveolus. Treatment included a partial mandibulectomy with a free osseocutaneous fibula flap reconstruction. He made a good postoperative recovery and was given adjuvant radiotherapy. No problems were reported with the donor site or ankle. Five months after harvesting the flap the patient sustained a fracture of the medial malleolus having jumped over a ditch playing golf. This was treated successfully with a below knee plaster of Paris cast. The interosseous membrane was not ruptured in the accident indicating that the distal fibula left in situ was adequate to maintain the integrity of the mortice. A degree of ankle instability may be present after fibula flap harvest which is only revealed by athletic activity.
