Objective: Rotational panoramic radiography is routinely used in dental practice. It has not been clarified, however, whether an accessory mental foramen can be demonstrated using this technique. The visibility of accessory mental foramina on rotational panoramic radiographs was compared with ...
This concludes a series of descriptive statistical reports on discrete cranial traits in 81 human populations from around the world. Four variants classified as vessel and nerve related characters were investigated: patent condylar canal, supraorbital foramen; accessory infraorbital foramen; and accessory ...

The presence of accessory foramina and canals in the mandible is frequently overlooked in clinical procedures. It is important to note that these anatomical variations may only be pre-surgically detected on imaging exams, and such detection may directly influence therapeutic success. We describe a previously unreported case of accessory ...
The modal or most common position of the mental foramen in the human mandible with respect to teeth appears to be below the second premolar regardless of race or age. The position of this structure was investigated in a sample of Asian Indians of unknown age or sex. In this study, 75.36% of 138 mandibular sides exhibited the position of the ...
In this retrospective study with limited cone-beam computed tomography (limited CBCT), we investigated the anatomic characteristics of the accessory mental foramina and accessory branches of the mandibular canal. The CBCT records of approximately 150 patients were evaluated, and 17 accessory ...
The retromolar foramen (RMF) was found to occur in eighteen of 234 adult human mandibles studied (7.7%). No statistically significant difference was found between left and right sides or between sexes. A statistical correlation was made between the occurrence of the RMF and accessory mandibular foramina, accessory ...
Correct identification of the causes of dental anesthetic failure is essential in order to adopt the required measures for successful anesthesia. A review is made of the factors implicated in locoregional anesthesia failure, such as a bifid inferior alveolar nerve, retromolar foramen associated to accessory innervation, double or ...
Analysis of retromolar foramen (RMF) in a large series of mandibles (N 2500) was undertaken to provide descriptive statistics for this variant. RMF of diameter 0.5 mm or greater were scored. Consistent with other data on accessory canals in the facial skeleton, RMF was found to occur more commonly in native populations of North America than in other ...
The position of the mental foramen was studied in 58 adult Turkish skulls which were divided into two groups according to age. A previously published method was used to determine the position of the mental foramen. The most common position of the mental foramen lies in line ...

OBJECTIVE: To evaluate the horizontal migration of the human mental foramen before and after birth. METHODS: 54 formalin-fixed fetuses between 17 and 32 weeks of gestation, and 94 panoramic radiographs of children aged between 4 and 12 years were investigated. The distances between the mental foramen and ...

Transverse foramens of 250 cervical vertebras were examined. There were accessory foramina and variations in shape and number in 10 out of 250 cervical vertebras. Since such a variation of foramens, through which the vertebral artery passes, has not been detected in the literature, these ten cases are to be considered. PMID:11534413

Information concerning the anatomy of the physiological foramen is limited. The aim of this study was to investigate the distance between the physiological and anatomical apex, accessory foramina frequency, and the shape and diameter of the physiological foramen in maxillary and mandibular molars. The apical anatomy of 523 maxillary ...
In view of the relevance of the mylohyoid nerve to clinical difficulties in achieving deep analgesia of the lower incisors, a dissection study was undertaken. Dissection from twenty-six adult cadavers of both sexes were studied with the aid of a dissecting microscope. The following observations were made: (1) A supplementary branch of the mylohyoid nerve entered the mandible through ...
PURPOSE:: To examine the positional relationship between the ethmoidal foramina and the frontoethmoidal suture. METHODS:: Eighty-four orbits of 42 Japanese cadavers (24 male and 18 female cadavers; average age at death, 81.0 years; range, 61-101 years), fixed in 10% buffered formalin, were used for investigation. The most anterior or posterior ethmoidal foramen was defined as ...

An unusual bony depression with accessory osseous passages in the right side of middle cranial fossa was observed in a dry adult human skull. It was located below the superior orbital fissure and optic canal. The bony depression was divided into two parts ,medial and lateral fossa, by an incomplete oblique bony septum. The foramen rotundum and an ...
We report a patient with herpes zoster oticus who presented with acute jugular foramen syndrome, and we present the review of 9 similar cases reported previously. Jugular foramen syndrome associated with varicella-zoster virus (VZV) infection is characterized by acute-onset dysphagia and dysphonia, usually accompanied or preceded by cranial, cervical, or ...
The location of the mental foramen on the mandibular corpus has figured prominently in debates concerning the taxonomy of fossil hominins and Gorilla gorilla. In this study we quantify the antero/posterior (A/P) position of the mental foramen across great apes, modern humans and Australopithecus. Contrary to most ...
A skeletal variant assay system (SVAS) consisting of a group of 88 spontaneously occurring qualitative variations of the adult mouse skeleton was applied to CD-1 animals that had been exposed in utero to 0, 200, or 1,000 mg/kg/day of the sodium salt of acetazolamide dissolved in distilled water, presented by SC injection of the dam during day 8 or days 9-11 of gestation. Two separate series of ...
A model of the acoustic field of interfering reflections from steel cylinders was developed. Analysis of the model showed the availability of great potential resources for a decrease of the influence of unwanted echoes and hence for increasing the signal-to-clatter ratio. The conformity of the available models of the echolocation hearing of the dolphin to the acoustic field of the clatter was ...

Even though the doubled foramen rotundum (FR) can be identified once within the literature, there are no details of the contents at that level. We present here an anatomical case demonstrating the maxillary nerve (MN) duplication at the level of an unilateral doubled FR: the accessory nervous trunk of the MN separately left the trigeminal ganglion on the ...
The location and course of the mandibular canal and multiple mental foramina are important in dental implant insertion and any surgical procedures involving the mandible. The purpose of the present investigation was to assess buccal foramen presence in the mandible using cone-beam computed tomography (CBCT) images. A total of 84 patients were enrolled in ...
IntroductionForeign bodies' entrapments in the mandibular and submandibular regions are quite common.Case presentationWe report an unusual case of foreign body (amalgam filling) entrapment over the mental foramen causing dysaesthesia in the distribution of the mental nerve. An interesting sign was blue discoloration of the overlaying ...
A previously undescribed anatomical variant is reported here, that of vermian arteries (vAs) branched from the vertebral arteries (VAs) and replacing the medial branches of the posterior inferior cerebellar arteries (PICAs) that, in turn, were leaving the basilar artery. Both vAs left the VAs in the foramen magnum. The left vA initially looped in front of the spinal root of ...
The lumbosacral spines of two fetal and twelve adult cadavers have been studied by dissection. Evidence shows that the fifth lumbar intervertebral foramen is crossed on its external aspect by a strong, cord-like corporotransverse ligament passing obliquely downwards, forwards and medially from the inferior aspect of the accessory process of the fifth ...
The work reports morphometric analysis of the skulls of the Sahel breed of goat. The calculated metric data (mean +/- SD) included the condylobasal length, 16.94 +/- 1.39 cm, while the orbital circumference was 11.30 +/- 0.48 cm. The foramen magnum height and width were 1.82 +/- 0.11 cm and 1.85 +/- 0.15 cm respectively while the foramen magnum index was ...

The mental foramen (MF) is an important anatomic landmark of the mandible, through which the mental nerve and blood vessels emerge. The importance of MF in dental practice is especially related to dental implants placement and other surgical procedures in the region. It is fundamental to be careful in order to avoid nerve and vessels ...
