Therefore, the surgery’s meticulous planning is essential to avoid such complications. This case report describes a 63-year-old male patient diagnosed with an impacted lower third molar (tooth #38) with concurrent basal cell carcinoma of the right ear and squamous cell carcinoma of the right vocal cord treated with radiotherapy. Taking into account the patient’s health status, a minimally invasive osteotomy and a corono-radicular separation procedure were performed. This procedure allowed us to reduce the risk of mandibular ORN. Three years later, the healing was complete, and the situation was stable.</p> Radiotherapy Chemotherapy Third molar extraction Dewey 617.6 Dewey 617 57 Département de chirurgie 222 214 Enseignement de chirurgie orale et implantologie 24R false 555 Groupe Scolozzi Paolo (chirurgie maxillo-faciale et buccale) 896 238 Groupe Lombardi Tommaso (médecine dentaire) 313 Discussion of clinical cases 9 2 3eb5eae8-740e-4eb1-9012-981e27b91a2c Article (Published version) Public Article-scientifique-from-unpaywall.pdf 1026309 application/pdf OA OTHER openAccess Faculté de médecine / Section de médecine clinique / Département de chirurgie Faculté de médecine / Section de médecine dentaire / Enseignement de chirurgie orale et implantologie
