    ABSTRACT: The inferiorly based buccinator myomucosal island flap is a useful reconstructive option for medium-sized intraoral mucosal defects. The pedicle length of this flap has not yet been determined. Thirteen fresh cadavers (26 sides) with intact faces were studied. An inferiorly based buccinator myomucosal island flap was elevated. Various measurements were taken, including pedicle length, paddle area, and pedicle length after dissection of the facial artery through the submandibular salivary gland; the presence of the facial artery or vein in the pedicle and the number of perforators were also evaluated. The mean pedicle lengths in the right and left sides were 4.8±0.6cm and 4.9±0.6cm, respectively. The mean pedicle lengths after dissection of the facial artery through the submandibular salivary gland were 7.8±0.7cm (right side) and 7.7±0.6cm (left side). The pedicle contained only the facial artery in six sides. There were two to three perforator branches from the facial artery to the mucosal paddle. Paddle sizes of the flap were in the range of 2.2×2.1cm to 3.5×3cm. This flap is suitable for the reconstruction of the floor of the mouth and tongue. Pedicle length can be increased significantly by dissecting the facial artery through the submandibular salivary gland.

    ABSTRACT: The aim of the present study was to compare two methods used in inferior alveolar nerve (IAN) repositioning to evaluate their effect on the vitality of intact teeth anterior to the mental foramen. Nerve lateralization (NL) is defined as the lateral reflection of the IAN without incisive nerve transection; nerve transposition (NT) involves sacrifice of the incisive nerve. Twenty-one patients were included in this study. Vitality tests for the teeth anterior to the mental foramen, including pulse oximetry and electric pulp testing, were evaluated at 1 week prior to surgery and at 1 week, 1, 3, 6, and 12 months after surgery. Lower lip and chin neurosensory changes were also recorded at the same time intervals by static light touch test with a cotton-tipped applicator and two-point discrimination test with sharp callipers. Vitality tests were negative after the operation in the NT group, while all had normal values at 1 week prior to the operation. In the NL group, only two patients (20%) had negative test results at 1 week after surgery. Lip and chin neurosensory changes in the total transpositions (28 operations) were seen in 7.1% at 1 year after the operation. It appears that NL is a more physiological procedure than NT.

    ABSTRACT: Vermilion lower lip cross flap is indicated for reconstruction of upper lip in residual deformities following trauma or cleft lip. Flap survival depends on incorporation of inferior labial artery in pedicle. This article reports measurement of vertical distance between inferior labial artery and vermilion surface under light microscope in midline sagittal cross-sectional specimens harvested from 22 fresh male cadavers, to design cross lip vermilion flap more accurately and reduce morbidity of donor site. This study is designed to measure vertical distance between uppermost parts of inferior labial artery to vermilion surface in 22 fresh male cadavers. Tissue specimens were taken from lower lip midline in sagittal plane. Histological sections stained with Hematoxylin-eosin were reviewed by Pathologist. Measurements were done by staged micrometer which was calibrated in 10 μm subdivisions under light microscope. Vertical distance was measured in millimeter and artery location was defined as submucosal, in superficial muscle and deep muscular layer. Descriptive study. Analysis of data shows that mean distance was 2.42 ± 1.67 mm. In 77.27% of cases, the artery was in submucosal layer and in 13.64% of cases this artery was located in superficial muscular layer. As a result 4-mm depth incision of lower lip vermilion that incorporate superficial layer of orbicularis oris muscle will ensure blood supply of lower lip vermilion cross flap.

    ABSTRACT: In oral cavity, the tongue is the most common site prone to development of squamous cell carcinoma (SCC). Considering malignant transformation as a cellular stress, the expression of heat shock proteins (HSPs) may be affected in this process. In this study we assessed the expression of HSP105 and HSP27 as two of the most interested stress proteins and investigated their relationship with grade and stage of the tongue SCC. Fifty-six specimens including 31 early and 25 advanced tongue SCC were gathered. All specimens were graded histologically from I to III. Sixteen sections of normal oral mucosa were used as control group. The cellularity and intensity of HSP105 and HSP27 expression were studied immunohistochemically in both case and control groups. Results were expressed by histochemical score (HSCORE). Significant differences were observed between expression of HSPs and stage of the disease. From early to advanced stage, the expression of HSP105 and HSP27 increased and decreased, respectively. There was no relationship between histological grade of lesion and HSCORE of HSP105 expression (P=0.5), although, HSP27 expression had reverse relationship with the SCC histological grade. HSP27 and HSP105 may be indicated for prognostic purposes in evaluation of tongue SCC. HSP 27 may be used for more accurate microscopic grading of tongue SCC. Increased expression of HSP105 in advanced stage may lead to using this protein for immunotherapy of tongue SCC.

    ABSTRACT: Schwannoma(neurilemmoma) is a benign tumor originates from Schwann cells. Ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. Head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. The mandible is the most common site of occurrence for this lesion. We report a rare case of intraosseous ancient schwannoma of the mandible in a 27-year-old woman patient. The tumor located in the ramus and angle region.
