“…The intraoral stent is an individualized mouth-opening device, which may be used during HNC RT with the intention of preventing unnecessary irradiation in normal adjacent tissue [57,58]. Several benefits have been described for the use of this device: It increases the distance between the mandible and the maxilla, focusing the radiation dose more precisely on the target volume, and immobilize the mandible (Fig.…”

“…Besides, its production is safe, easy to fabricate and comfortable to wear [58][59][60]. Recent studies have investigated the use of this device with the intention of minimizing the adverse effects of radiation, including osteoradionecrosis, oral mucositis and xerostomia [57][58][59][60][61].…”

“…In 2013, our group at AC Camargo Cancer Center was the first to conduct a dosimetric study [57] in a patient with squamous cell carcinoma of the tongue who underwent IMRT, comparing the tomography computer preirradiation planning with and without the use of the intraoral stent. This study showed that the area of the maxillary teeth, hard palate, both parotid glands and the left submandibular gland were more preserved from the radiation dose with the use of the device than without it, with no effect on the target structure.…”

Xerostomia or dry mouth is one of the most common and disturbing adverse effects following radiotherapy for head and neck cancer (HNC). This complication strongly increases the risk for dental caries, difficulties with chewing, swallowing and sleep disorders with significant impact on patients' quality of life. Current treatment approaches of xerostomia are often difficult and bring in many cases no substantial relief for the patient. This paper discusses the clinical features and current knowledge of xerostomia prevention in order to evaluate the real possibilities of reducing the incidence and severity of this complication in HNC patients. Salivary gland cytoprotectants (amifostine), muscarinic agonist stimulation (pilocarpine and bethanechol), salivary gland-sparing radiation technique (intensity-modulated radiotherapy-IMRT), surgical relocation of the submandibular gland, intraoral stent and stem cell transplantation are promising techniques that are discussed in this study.

“…Sinaran terkena pada lantai mulut atau lipatan sublingual kerana mobiliti struktur yang terlibat akan memberi kesan kepada maksila dan meningkatkan risiko osteoradionekrosis. Penggunaan peranti ini dapat meningkatkan jarak antara mandibel dan maksila seterusnya melindungi maksila daripada bahaya sinaran (Verrone et al 2013).…”

Kejituan persediaan rawatan dengan teknik yang kesamabentukannya tinggi seperti terapi isi padu arka termodulat (VMAT) berupaya mengurangkan dedahan dos sinaran yang berlebihan di bahagian mukosa oral. Oleh itu, satu kajian telah dijalankan untuk meningkatkan kejituan persediaan rawatan antara-pecahan rawatan dengan mengenal pasti penggunaan peranti cegah gerak yang sesuai. Seramai dua belas pesakit kanser mulut terlibat dalam kajian ini. Mereka dikategorikan kepada tiga kumpulan yang menggunakan peranti cegah gerak yang berbeza; HFW: headFIX ® mouthpiece dibentuk dengan lilin, SYR: 10 cc / ml picagari dan TDW: lilin dibentuk pada kayu penekan lidah. Sebelum rawatan diberikan, pesakit menjalani radioterapi berpandukan imej (IGRT) bagi pengukuran ralat persediaan rawatan posisi. Sejumlah 292 set imej tomografi berkomputer bim-kon (CBCT) diperolehi. Perbezaan pada translasi (lateral, longitudinal, vertikal) dan rotasi (pic, guling, rewang) dalam setiap imej CBCT ditentukan. Ralat posisi pesakit dianalisis untuk aliran masa sepanjang radioterapi. Pengiraan ralat sistematik (Σ) dan rawak (σ) dilakukan dan margin CTV-PTV ditentukan. Min ± SD bagi ralat persediaan rawatan mutlak untuk HFW adalah paling rendah (p < 0.001) untuk semua ralat translasi

Benefits of intraoral stents in patients with head and neck cancer undergoing radiotherapy: Systematic review

et al. 2021

View full text Add to dashboard Cite

Intraoral stents aim to reduce the oral complications associated with head and neck cancers radiotherapy. The aim of this study is to determine the benefits associated with these devices. A systematic review was conducted in PubMed, Web of Science, and Scopus databases selecting full articles published in English, Portuguese, or Spanish until June 6, 2020 (PROSPERO registration: CRD42020185065). The studies were evaluated by Hadorn and Somerfield criteria and guidelines were established. Nineteen studies were identified suggesting the use of intraoral stent for radiotherapy for patients with cancer on/near the mandible to reduce oral mucositis, trismus, xerostomia (LoE III), and dose in healthy structures (LoE IV) and for cancer on/near the maxilla to reduce oral mucositis and dose in healthy structures (LoE IV). Despite the limited scientific evidence, several benefits associated with the use of intraoral stent for radiotherapy of the head and neck neoplasia have been reported.

Impact of intraoral stent on the side effects of radiotherapy for oral cancer

Abstract: This article shows that intraoral stents seem to be useful in decreasing the radiation dose to healthy structures, especially in bone structures and salivary glands during radiotherapy, and emphasizes the importance of a multidisciplinary team during oncological therapy.
