The infraorbital nerve (ION) supplies the skin and mucous membranes of the middle portion of the face. This nerve is vulnerable to injury during surgical procedures of mid-face. Severe pain and loss of sense are noted in patients whose infraorbital nerve is either entirely or partially lost after these surgeries. We investigated the distribution area and topography of the ION, about which little is currently known, by dissecting 43 hemifaces of Korean cadavers. The ION produced four main… 

Variant Anatomy of the Nasal and Labial Branches of the Infraorbital Nerve

This detailed study reveals additional variations in the emergence and branching pattern of the ION that underlie the lack of response to surgical treatment for trigeminal neuralgia and also the need for a filtration to achieve full anesthesia after ION block.

Anatomical study of the internal nasal branch of the infraorbital nerve

The results of this study are the first to detail the topography of the internal nasal branch of the ION, which runs down the nose and around the ala to be distributed to the nasal septum and vestibule.

Variations in Emergence and Course of the Inferior Palpebral Nerve

Information is provided on the additional variations of the main infraorbital nerve with reference to the inferior palpebral nerve that may account for the difficulties and complications encountered in clinical interventions that will improve clinical management of conditions affecting the region of distribution of the IP nerve.

Previously undescribed palpebral branch from the infraorbital canal: Application to surgery of the eyelid and treatment of orbital floor fractures

This study investigates another, to the authors' knowledge, previously unknown branch of the infraorbital nerve, and suggests it should be named the “posterior IPb” of the ION, which might decrease sensory loss following invasive procedures of the lower orbit.

A Variation of the Infraorbital Nerve: Its Potential Clinical Consequence Especially in the Treatment of Trigeminal Neuralgia Case Report

Although apparently uncommon, derangement of the infraorbital nerve should be kept in mind by surgeons during surgical procedures in the region for treatment of various disorders including trigeminal neuralgia.

A Cadaveric Study of the Communication Patterns Between the Buccal Trunks of the Facial Nerve and the Infraorbital Nerve in the Midface

This study aimed to clarify and classify patterns of proximal communications between the buccal branches of the facial nerve and the infraorbital nerve and found that Communications between the motor and the sensory nerves in the midface may be important to increase nerve endurance and to compensate functional loss from injury.

The Morphology of the Infraorbital Nerve and Foramen in the Presence of an Accessory Infraorbital Foramen

The area of the ION is not affected by an AIOF, suggesting that the field of innervation of this area is not modified by its occurrence, however, the IONS appears to divide more proximally into its component branches when the A IOF is present.

Anatomic Study of Accessory Infraorbital Nerves and Foramina: Application for a Better Understanding of Complications of Le Fort Fractures and Osteotomy.

A Cadaver Study to Assess the Feasibility of a Cross-Nerve Transfer of the Infraorbital Nerve for Patients With Peripheral Infraorbital Nerve Injury

The results imply the feasibility of a cross-nerve transfer of the distal part of the infraorbital nerve, based on a cadaver study.



Cutaneous Distribution of Infraorbital Nerve

The nonoverlapped branch of the infraorbital nerve exhibits a restricted anesthesia, but the overlapped branch sustains sensory perception to some extent when being damaged.

Communication of Infraorbital Nerve and Facial Nerve: Anatomic and Histologic Study

The aim of the study is to elucidate additional detailed anatomy of the infraorbital plexus, consisting of the superior labial branch of the incisive nerve and facial nerve in the cheek, and to keep in mind when performing any procedures related to zygoma, maxilla, or deep cheek injuries.

Infraorbital nerve block in neonates for cleft lip repair: anatomical study and clinical application.

These measurements were used to perform bilateral infraorbital nerve blocks in four neonates undergoing cleft lip surgery under general anaesthesia, thereby providing analgesia with minimal risk of respiratory depression.

Recovery of infraorbital nerve function after zygomaticomaxillary cheek pedicled flap.

Infraorbital nerve recovery after minimally dislocated facial fractures

According to the findings, exploration of the orbital floor or an attempted elevation of a minimally or nondislocated fracture of the ZMC does not enhance the recovery of the infraorbital nerve, and the procedure may itself increase the morbidity and sensory dysfunction.

A study of infraorbital foramen, canal and nerve in adult Egyptians.

The infraorbital foramen, canal and nerve were examined in 30 Egyptian adult skulls and 15 adult human cadavers and the panoramic view showed to be better than either of the lateral or the postero/anterior view.

PURPOSE The aim of this study was to document the variability in the position of the infraorbital foramen with relation to the facial midline, infraorbital rim, supraorbital notch, and maxillary

The results suggested that lesions along the ION pathway may impair the afferent pathway of the blink reflex, and R1 is more effective than R2 in detecting ION defects.

Paraesthesia of the infraorbital nerve following fracture of the zygomatic complex.

Bilateral infraorbital nerve block is superior to peri-incisional infiltration for analgesia after repair of cleft lip.

It is concluded that infraorbital nerve block with 0.125% bupivacaine provides better and more prolonged analgesia than peri-incisional infiltration in cleft lip repair.
