Xia Y, Feng ZC, Li C, Wu H, Tang C, Wang L, Li H. Application of additive manufacturing in customized titanium mandibular implants for patients with oral tumors. Oncol Lett 2020; 20:51. [PMID: 32788938 PMCID: PMC7416405 DOI: 10.3892/ol.2020.11912] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Accepted: 06/18/2020] [Indexed: 01/03/2023] Open
Abstract
The application of additive manufacturing (AM) technology has been widely used in various medical fields, including craniomaxillofacial surgery. The aim of the present study was to examine the surgical efficiency and post-operative outcomes of patient-specific titanium mandibular reconstruction using AM. Major steps in directly designing and manufacturing 3D customized titanium implants are discussed. Furthermore, pre-operative preparations, surgical procedures and post-operative treatment outcomes were compared among patients who received mandibular reconstruction using a customized 3D titanium implant, titanium reconstruction plates or vascularized autologous fibular grafting. Use of a customized titanium implant significantly improved surgical efficiency and precision. When compared with mandibular reconstruction using the two conventional approaches, patients who received the customized implant were significantly more satisfied with their facial appearance, and exhibited minimal post-operative complications in the 12-month follow-up period. Patients who underwent mandibular reconstruction using a customized titanium implant displayed improved mandibular contour symmetry, restored occlusal function, normal range of mouth opening and no temporomandibular joint related pain; all complications frequently experienced by patients who undergo conventional approaches of mandibular reconstruction.

Oba MK, Innocentini LMAR, Viani G, Ricz HMA, de Carvalho Reis T, Ferrari TC, de Macedo LD. Evaluation of the correlation between side effects to oral mucosa, salivary glands, and general health status with quality of life during intensity-modulated radiotherapy for head and neck cancer. Support Care Cancer 2020; 29:127-134. [PMID: 32318870 DOI: 10.1007/s00520-020-05454-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 04/01/2020] [Indexed: 12/19/2022]
Abstract
PURPOSE The aim of this study was to evaluate the distribution of acute clinical complications that involve the oral cavity (oral mucositis and salivary flow), general health status (Karnofsky performance status scale (KPS) and weight), and quality of life using the worst performance throughout radiotherapy treatment by intensity-modulated radiation therapy (IMRT) in the head and neck region and to evaluate the correlation between these variables. METHODS This prospective, longitudinal study evaluated 32 patients who were undergoing IMRT for head and neck tumors. The measures were collected weekly through standardized protocols and a quality of life questionnaire (UW-QOL version 4). RESULTS The worst performance for all variables was concentrated in treatment weeks 2 and 5. Regarding quality of life, the emotional dimensions were the most affected (pain 62.86; activity 55; recreation 43.57; mood 49.97; shoulder 57.06; anxiety 42.91). There were a higher number of moderate mucositis correlations with quality of life (mucositis × KPS 0.002; mucositis × weight loss 0.03; mucositis × pain 0.001; mucositis × activity 0.002; mucositis × recreation 0.001; mucositis × swallowing 0.002; mucositis × saliva 0.006; mucositis × mood 0.007; mucositis × anxiety 0.002). CONCLUSIONS IMRT treatment severely deteriorated the patients' quality of life. There were important correlations between the clinical variables and quality of life, especially mucositis.
