using P45 plastination concorded well with Mitz’s original drawing. We suggest that the results of the present study may be helpful for practicing surgeons to apply in subcutaneous dissection or sub-SMAS dissection in facelift procedures.

Isolated zygomatic arch fractures are common fractures in maxillofacial trauma. These fractures can trigger a functional alteration in the mouth opening and closing. Until now, there is no published classification of an isolated zygomatic arch fracture that contains the presence or not of coronoid impingement. So we propose a new classification that is easy to handle and has the largest number of scenarios that can occur in this type of fracture. The isolated zygomatic arch fracture is classified as Type I Nondisplaced fractures, Type II Greenstick fracture with or without coronoid impingement, Type III Single displaced fracture with or without coronoid impingement, Type IV Multiple displaced fracture with or without coronoid impingement, Type V Comminuted fracture with or without coronoid impingement. We consider it to be a comprehensive classification, with general concepts of bone fractures, that can be incorporated into professional daily practice.

The aim of this study was to compare the lateral tooth volume and morphology differences between buccally and palatally localized unilateral impacted maxillary canine (IMC) patients with volumetric and linear measurements on cone-beam computed tomography (CBCT) records. CBCT records of 48 individuals with 24-buccally and 24-palatally localized unilateral IMCs were included to the study. The patients comprised 34 females, 14 males, with a mean age of 17.71 (±SD 6.63 years). This split-mouth, retrospective case-control, study consisted of buccally and palatally IMC group, and each group was categorized into 2 sub-groups as impacted and erupted side. Lateral tooth volume, tooth length, mesiodistal-buccolingual crown widths, mesiodistal- buccolingual root widths at cemento-enamel junction (CEJ), at 4 mm apical to CEJ, at 8 mm apical to CEJ, mesiodistal crown-root angle, arch perimeter measurements were performed on CBCT images. The data were analyzed by factorial design repeated measures ANOVA. Bonferroni test d crown-root angle of the lateral were narrower on impacted side than erupted side. The volume and crown widths of lateral incisor are effective in sagittal localization of IMC. The shorter length, narrower apical root morphology and mesially inclined crown-root angle of lateral incisor are noteworthy on impacted sides, regardless of sagittal position of IMC.

The aim of this study was to evaluate the normal dimensions and shape of the sella turcica (ST) in the Turkish population using multidetector computed tomography.

This single-center, retrospective study included 188 patients who met the study criteria and had paranasal multidetector computed tomography taken between January 2019 and December 2019. The patients included in the study comprised 77 females and 111 males. The whole patient group was separated into 3 age groups of 18 to 25 years (group 1), 25 to 40 years (group 2), and 40 years and over (group 3). They were also separated according to gender.

The mean length of the ST was determined as 8.52 ± 1.42 mm (min-max 4.61-12.73 mm), mean height as 7.00 ± 1.31 mm (min-max 3.00-10.51 mm), mean aperture as 6.50 ± 2.00 mm (min-max 2.24-12.51 mm), and mean width as 11.01 ± 1.50 mm (min-max 7.78-14.94 mm). No statistically significant difference was determined between the length, height, width, and aperture size values of the ST according to gender and age groups.

The results of this study demonstrated no significant difference in ST dimensions according to gender or age groups. It can be considered that the shape and dimensions of the ST can be more accurately evaluated with computed tomography and classification can be more robustly applied.

Although costal cartilage has many uses and is a reliable source of cartilage for rhinoplasty procedures, donor-site complications may arise with conventional harvesting techniques. The present report reports a novel technique of harvesting costal cartilage using a specially designed scalpel and studies the use of the harvested cartilage in the reconstruction of secondary nasal deformities in patients with cleft lips.

Ten patients (7 females and 3 males) with nasal deformities secondary to cleft lip underwent rhinoplasty using this new technique at the Department of Oral and Maxillofacial Surgery, Second Hospital of Hebei Medical University, China, between May 2011 and December 2013. Clinical outcomes were evaluated with a follow-up period of 6 to 30 months.

The new technique successfully corrected primary nasal deformities, including flat nasal tip, short columella, flaring alae, and asymmetrical nostrils. Selleckchem SB415286 Surgeons and patients assessed the outcome to be either good or satisfactory. Patients experienced transient discomfort at the wound site but there were no major complications (such as wound infection, dehiscence, exposure, graft extrusion, and pulmonary involvement).
