    Background : Post-operative complications of various degrees of severity are commonly observed in third molar impaction surgery. For this reason, a surgical procedure that decreases the trauma of bone and soft tissues should be a priority for surgeons. In the present study, we compare the efficacy and the post-operative complications of patients to whom two different surgical techniques were applied for impacted lower third molar extraction. Material and Methods : Patients of the first group underwent the classical bur technique, while patients of the second group underwent another technique, in which an elevator was placed on the buccal surface of the impacted molar in order to luxate the alveolar socket more easily. Results: Comparing the two techniques, we observed a statistically significant decrease in the duration of the procedure and in the need for tooth sectioning when applying the second surgical technique, while the post-operative complications were similar in the two groups. We also found a statistically significant lower incidence of lingual nerve lesions and only a slightly higher frequency of sharp mandibular bone irregularities in the second group, which however was not statistically significant. Conclusions: The results of our study indicate that the surgical technique using an elevator on the buccal surface of the tooth seems to be a reliable method to extract impacted third molars safely, easily, quickly and with the minimum trauma to the surrounding tissues

    THE STIMULUS FOR THE STUDY OF ESTROGENS' INFLUENCE ON THE HEALING PROCESS OF FRACTURES WAS THEIR KNOWN CONTRIBUTION TO THE RESTRAINT OF THE OSTEOLYTIC PROCESSWHICH OCCURS IN OSTEOPOROSIS. FRACTURES WERE EXPERIMENTALLY CAUSED TO THE ANGLE OF THE MANDIBLE OF 63 FEMALE WISTAR RATS. TWENTY ONE OF THE ANIMALS COMPOSED THE CONTROL GROUP. BENZOIC ESTRADIOL WAS ADMINISTERED INTRAMUSCULARY TO ANOTHERGROUP CONSISTED OF 21 ANIMALS AND OVARIECTOMY WAS PERFORMED TO ALL 21 ANIMALS OF THE THIRD GROUP, FOUR WEEKS BEFORE THE FRACTURES' DAY. THE STUDY METHOD USEDCOMPRISED: 1) RADIOLOGICAL EVALUATION OF THE HISTOLOGICALLY FIXED FRACTURED AREA OF THE MANDIBLE, 2) HISTOLOGICAL EXAMINATION OF THE SAME AREA, 3) BLOOD ESTRADIOL MEASUREMENT USING RIA METHODS 4) BODY WEIGHT MEASUREMENT IN VARIOUS STAGES OF THE EXPERIMENT. THE RATS WERE SACRIFICED ON THE 7TH, 14TH AND 21ST POST-FRACTURE DAY CONSEQUENTLY. WE CONCLUDE THAT: 1) BENZOIC ESTRADIOL WHEN ADMINISTERED BY THE METHOD WHICH WAS USED IN THE PRESENT STUDY IS POSITIVELY INFLUENCES THE HEALING PROCESS OF MANDIBULAR FRACTURES IN YOUNG FEMALE WISTAR RATS. HEALINGIS ALSO INFLUENCED BY THE EXACT SITE TO THE FRACTURE LINE AS FAR AS ITS LINE OF DIRECTION IS CONCERNED; THEY ARE NOT HOWEVER INFLUENCED BY THE TEETH POSITION, 3)OVARIECTOMY INCREASES BODY WEIGHT WHEREAS ESTROGENS ADMINISTRATION RESULTS IN ITS LOSS.Η ΘΕΤΙΚΗ ΣΥΜΒΟΛΗ ΤΩΝ ΟΙΣΤΡΟΓΟΝΩΝ ΣΤΗΝ ΚΑΘΥΣΤΕΡΗΣΗ ΤΗΣ ΟΣΤΕΟΛΥΤΙΚΗΣ ΔΙΕΡΓΑΣΙΑΣ ΠΟΥ ΣΥΜΒΑΙΝΕΙ ΣΤΗΝ ΟΣΤΕΟΠΟΡΩΣΗ ΑΠΟΤΕΛΕΣΕ ΤΟ ΕΝΑΥΣΜΑ ΓΙΑ ΤΗ ΜΕΛΕΤΗ ΤΗΣ ΕΠΙΔΡΑΣΗΣ ΤΩΝ ΟΙΣΤΡΟΓΟΝΩΝ ΣΤΗ ΔΙΕΡΓΑΣΙΑ ΤΗΣ ΠΟΡΩΣΗΣ ΚΑΤΑΓΜΑΤΩΝ ΠΟΥ ΕΓΙΝΑΝ ΣΤΗ ΓΩΝΙΑ ΤΗΣ ΚΑΤΩ ΓΝΑΘΟΥ ΣΕ 63, ΘΗΛΥΚΟΥ ΓΕΝΟΥΣ, ΕΠΙΜΥΕΣ ΤΗΣ ΦΥΛΗΣ WISTAR.

    Synchronous Ganglioneuroma and Schwannoma Mistaken for Carotid Body Tumor

    No full text
    Ganglioneuromas are a very rare benign neural tumor, commonly derived from the ganglia of the sympathetic system, and are composed of mature Schwann cells, ganglion cells, and nerve fibres. They may arise anywhere from the base of the skull to the pelvis along the paravertebral sympathetic plexus. We report a rare case of synchronous ganglioneuroma and schwannoma, mistaken for carotid body tumor. The coexistence of these two entities in head and neck region is very rare

    Chondroid Syringoma of the Medial Canthus

    Chondroid syringoma, or pleomorphic adenoma of the skin, is a rare, benign skin adnexal tumor. It is usually exhibited as a slowly growing intradermal or subcutaneous nodule, typically located in the head and neck region. Because of the unremarkable clinical symptomatology of this rare tumor, the diagnosis is exclusively made retrospectively based on histological confirmation of the surgically excised tumor. We present a rare case of a chondroid syringoma located in the left medial canthus of a 58-year-old man. The patient had no symptoms and decided to excise it for cosmetic reasons only. Local excision with a macroscopic wide cuff of normal tissue was done, without destroying the aesthetic and functional structures, since the defect was restored by a finger flap. One year postoperatively, the patient has remained disease-free. Chondroid syringoma usually appears in the face but the location in the medial canthus is not mentioned in the literature for the last twenty years

    Anterolateral thigh harvesting for head and neck reconstruction without Doppler: Risky or not?

    No full text
    Background: Anterolateral thigh flap (ALT) is used as a workhorse flap for head and neck reconstruction. The most used method to map the perforators nowadays is hand-held Doppler although several more sophisticated techniques have been described. This paper is to investigate whether harvesting the ALT flap without preoperative mapping is safe. Materials and methods: Twenty consecutive patients were randomly assigned to one of two groups: A or B. Patients of A group (n = 10) were marked before the operation with the use of a Doppler probe whilst patients of group B (n = 10) were not marked preoperatively using Doppler to detect the perforators. Complications and time of ALT dissection were documented. Results: There was no statistical difference of complications between the two groups. Mean time of flap harvesting (skin incision up to main pedicle) was approximately 140 min in group A and 165 min in group B (statistically significantly less in group A p = 0.008). Conclusions: This paper is an indication that harvesting the ALT flap without preoperative mapping, even with hand-held Doppler, does not compromise safety of the procedure although operative time is prolonged
