Oral Squamous Cell Carcinomas Developing from Oral Lichen Planus: A 5-21 year Retrospective Study.

Background And Aims: There is insufficient data regarding clinical characteristics, relapse rates, as well as lymph node metastasis of squamous cell carcinomas of the oral cavity (OSCC) developing from oral lichen planus (OLP-OSCC). The aim of this retrospective study was to evaluate clinical characteristics, as well as relapse, recurrence and survival rates of OLP-OSCC.

Methods: In a retrospective monocenter analysis, all consecutive patients with an OSCC treated in the time period 1st January 2000-December 31 2016 were reviewed.

The Efficiency of a Learning Software Compared to e-Books in Dental Education.

Objectives:  Due to time-consuming curricular and extracurricular activities, students in dentistry and medicine can profit from efficient learning strategies. One strategy could be the preparation with individually designed educational software that embed different multimedia sources. The aim of this study was to determine the efficiency of such a program compared with an e-book similar to a traditional textbook.

The role of diabetes mellitus on the formation of severe odontogenic abscesses-a retrospective study.

Objectives: To analyze the correlation of diabetes mellitus and hyperglycemia with severe odontogenic abscesses.

Materials And Methods: Records of all patients in the Department of Oral and Maxillofacial Surgery of the Medical Center of the Johannes Gutenberg-University who underwent inpatient treatment for severe odontogenic abscesses between 2010 and 2016 were evaluated retrospectively regarding diabetes anamnesis, maximum and fasting blood sugar count, and duration until discharge. In order to compare the numbers to a general maxillofacial group, all patients who received inpatient treatment in 2013 for any diagnosis other than an abscess of the head and neck region were analyzed as well, and the numbers were correlated.

Factors accelerating recurrences and secondary tumors in cutaneous squamous cell carcinoma.

To investigate factors that affect and also decrease the duration for recurrences and secondary tumors in cSCC. A retrospective study was conducted for all patients who were treated for a cSCC of the head and neck between 2009 and 2016. Anamnestic as well as epidemiological and histological data were noted and correlated with the occurrence of recurrences and secondary cancers.

Sentinel lymph node biopsy in malignant melanoma of the head and neck.

Background: The aim of this retrospective study was to investigate sentinel lymph node biopsy in patients with head and neck melanoma.

Materials And Methods: Patients who underwent SLNB between 2010 and 2016 were comprised. Epidemiological, radiological, and surgical data were collected and compared to histological findings.

Outcome and cervical metastatic spread of squamous cell cancer of the buccal mucosa, a retrospective analysis of the past 25 years.

Objectives: Because of the low proportion of squamous cell carcinomas (SCCs) of the buccal mucosa within the carcinomas of the oral cavity in the Western population, data concerning metastatic pattern are sparse. Therefore, this retrospective study is focusing on the occurrence of cervical metastases (CM) and the overall outcome of this tumor entity.

Materials And Methods: From January 1988 to October 2013, 113 patients were treated in the Department of Oral and Maxillofacial Surgery, Mainz, for an oral SCC of the cheek.

Cervical metastases behavior of T1-2 squamous cell cancer of the oral mucosa.

Objectives: The clinical management of the neck of patients with early-stage oral squamous cell cancer (OSCC) is still controversially discussed in the current literature. This study analyzes histo-clinical factors influencing the occurrence of cervical lymph node metastases (CM).

Materials And Methods: In a retrospective mono-center study, patients with a primary T1-2 OSCC between 2000 and 2014 were analyzed regarding histo-clinical parameters possibly influencing the CM rate and the outcome.

Malignant lymphomas in the head and neck region--a retrospective, single-center study over 41 years.

Objectives: Non-Hodgkin lymphomas are malignant neoplastic proliferations of the immune system that can manifest as nodal or extranodal lymphomas. The aim of this study was to retrospectively investigate the site of occurrence of lymphomas in the head and neck area and to analyze the typical symptoms of patients who presented at an oral and maxillofacial surgical department.

Material And Methods: All patient files from 1971 until 2012 from an Oral and Maxillofacial Surgery of a University were analyzed for the diagnosis non-Hodgkin lymphoma.
