The purpose of this experimental study was to investigate the disseminating routes of viruses, bacteria, tumor cells and various substances along the trigeminal nerve sheaths. Thirty-four rabbits weighing approximately 3 kg were used for this study. After an intraperitoneal injection of sodium pentobarbital, the left infraorbital foramen was exposed surgically. Then, various amounts of Indian i...

Standard single-unit recording and stimulation techniques were used to assess the topographic organization, receptive field properties, and projections of cells (n = 297) in the ophthalmic-maxillary part of the trigeminal ganglion in 6 normal adult rats and 15 adults with unilateral infraorbital nerve section at birth (cells recorded ipsilateral to lesion: n = 641; cells recorded on the intact ...

Dry eye syndrome is caused by a reduction in the volume or quality of tears. Here, we show that pituitary adenylate cyclase-activating polypeptide (PACAP)-null mice develop dry eye-like symptoms such as corneal keratinization and tear reduction. PACAP immunoreactivity is co-localized with a neuronal marker, and PACAP receptor (PAC1-R) immunoreactivity is observed in mouse infraorbital lacrimal ...

BACKGROUND The aim of the study was to precisely describe and classify the infraorbital canal/groove (IOC/G) complex in dry human skulls and to evaluate the presence of asymmetry in the IOC/G complex. MATERIALS AND METHODS Seventy orbits of 35 human skulls were investigated.The following distances were measured: the distance between the posterior and anterior margin of the infraorbital groove...

BACKGROUND AND PURPOSE Although orbital fractures are common, orbital cellulitis rarely develops following orbital fracture. We hypothesized that compromise of the blood supply to the intraorbital fat during orbital floor fracture is responsible for this condition. The purpose of this study was to determine whether or not the lower intraorbital fat is supplied by a branch of the infraorbital ar...

BACKGROUND The aim of the study was to determine the localisation of the infraorbital foramen in relation to chosen anthropometric landmarks as novel reference points: nasion, rhinion, and frontomalare orbitale, and to verify their symmetry. MATERIAL AND METHODS Sixty-four sides of thirty-two human skulls were investigated. The distances between the infraorbital foramina and nasion, rhinion, ...

INTRODUCTION The reconstruction of soft tissue detects in mid facial region are highly demanding. Most challenging region are nasal alla. For full thickness nasal alla defects most authors use nasolabial flap based on facial/angular arcade, but for recidivans tumors the infraorbital perforator flap is a good solution. AIM The aim of our research was to analyze the number and the course of the...

Infraorbital nerve block in neonates is not well described although it has been suggested that bilateral infraorbital nerve block is the local analgesic technique of choice for early repair of cleft lip. The purpose of this study was to determine the location of the infraorbital nerve in neonatal cadavers and to identify clinically useful landmarks. Thirty infraorbital nerves were identified in...

Two patients, a woman aged 34 and a man aged 56, were included in the study. They reported the existence of pain in the areas of the infraorbital nerve, which, over the last four to five years, aggravated by the stimuli of eating, laughing, and being touched. 2 ml of 0.5% lidocaine was administered to these patients six times percutaneously. It was observed that the ease of pain lasted until th...

Cross sectional observational study was carried out to estimate the prevalence of accessory infraorbital foramen on both sides in a collection of 200 skulls available in the Department of Anatomy, St John’s Medical College, and other medical colleges of Bangalore. India. The data of the present study will be of considerably use to cliniciansanaesthetist following failure of infiltration of anae...
