The prevalence of head and neck cancers increases worldwide, the therapeutic arsenal of its management mainly includes surgery, radiotherapy (RTH), and the combination of these two therapies. Chemotherapy is also used as an adjuvant treatment. Brachytherapy (BT) is indicated for localized head and neck cancers of the tumors of the lips and the nasal pyramid, the oral cavity, and the oropharynx. Lead protection and positioning splints are generally used when BT is provided. They help protect uninvolved tissues as the dose that will be delivered is important. They are made before BT and positioned during irradiation. This case report presents a clinical case of a patient with lip cancer for treatment with BT and for which a lead protection splint for maxillary arch protection and mandibular positioning splint was given.
