Preoperative MRI for oral tongue squamous cell carcinoma: timing and correlation to histopathology.

Magnetic resonance imaging (MRI) is an integral part of the evaluation of local and regional disease in tongue squamous cell carcinoma prior to surgery. The aim of this study was to evaluate the accuracy of MRI in assessing tumour dimensions, as well as the impact of the time-lag from diagnostic biopsy on the accuracy of MRI. The medical records of 64 patients with tongue carcinoma were reviewed retrospectively. Tumour maximum diameter and tumour depth of invasion were compared between pathology and MRI (T1- and T2-weighted). MRI-derived maximum tumour diameter and depth of invasion correlated strongly with histopathology: T1-weighted (r = 0.700 and r = 0.813, respectively) and T2-weighted (r = 0.734 and r = 0.834, respectively). A significant correlation was found between measurements on T1 and T2 MRI for both parameters (P = 0.955 and P = 0.984, respectively). The accuracy rate of MRI for T-staging of early tumours was low: 10% for T1 tumours; 39.3% for T2 tumours. A time-lag of less than 2 weeks between the diagnostic biopsy and MRI adversely affected the correlation of tumour dimensions. MRI is a reliable tool for evaluating tongue carcinoma; however, it overestimates early tumours. A 2-week delay after diagnostic biopsy is desired before completing an MRI. Alternatively, if logistics allow, a pre-biopsy MRI is preferred, especially for T1-T2 tumours.

Repair of frontal sinus fractures: clinical and radiological long-term outcomes.

OBJECTIVE: The long-term clinical and radiological outcomes of patients surgically treated for frontal sinus fracture were assessed. METHODS: A retrospective, single-centre analysis was conducted of patients treated for frontal sinus fracture in a tertiary trauma centre between 2000 and 2017. Patients who underwent surgical repair for frontal sinus fracture followed by clinical and radiographical evaluation for at least six months were included. RESULTS: Of 338 patients admitted with frontal sinus fracture, 77 were treated surgically. Thirty patients met the inclusion criteria for long-term follow-up. The average follow-up duration was 37 months (range, 6-132 months). Reconstruction, obliteration and cranialisation of the frontal sinus fracture were performed in 14, 9 and 7 patients, respectively. Two patients with a reconstructed frontal sinus and one with an obliterated frontal sinus developed mucoceles. One patient developed forehead disfigurement following obliteration. CONCLUSION: Long-term complications of frontal sinus repair using the chosen repair techniques are rare, but patients need to be made aware of these potential complications.

[Dental care to the Israeli Defense Forces' fighters].

The combat soldiers of the Israeli Defense Forces (IDF) get comprehensive dental care. The service of a combat soldier in the IDF can be divided into two periods: the period of training that includes basic training and advanced training lasting six to eight months, followed by a period of operational activity within the framework of the battalions. Throughout his service, the combat soldier is exposed to dental disease including dental caries, periodontal disease and dental trauma attributed to his terms of service with low availability to maintain adequate oral hygiene in high intensity training. There is no available data as to the dental status of new recruits. This information is needed in order to determine the level of oral and dental health among combatsoldiers in order to guarantee operational continuity. Every recruit undergoes a full dental examination in order to determine his level of oral and dental health. From this point on, dental treatment is offered and performed according to the level of oral and dental health, in order to treat the most severe levels. The dental treatment is carried out so that throughout his service, the combat soldier is summoned to various dental clinics: the base unit training clinic, clinics serving the Brigades and experts clinics. All the factors mentioned above, are designed to help increase the provision of therapy, and lead to an increase in the number of fighters who receive comprehensive dental care.

[The crucial role of forensic odontology in the IDF].

Israel's recent military engagements have been asymmetric in nature, defining the captivity of a solider as the enemy's' strategic achievement. Casualty care during war, is a delicate mission, requiring the collaboration of 3 distinct corps - the medical corps, chaplaincy corps and the adjutant corps. In this article, we will review the crucial role forensic odontologists play in the identification of casualties. In addition to biometric identification which is carried out through DNA analysis, fingerprint co-matching and forensic odontology, the forensic battalion of the medical corps investigates the cause of death, delivering crucial information to different branches of the military.
