Peripheral nerve regeneration and intraneural revascularization. Neovius E, Fransson M, Persson C, Clarliden S, Farnebo F, Lundgren TK. 2. Patients undergoing repair should have the vision checked in the recovery room to ensure there is no intraoperative loss of vision, and then can be seen one week postoperatively, 3 weeks postoperatively, and 2-3 months postoperatively. Maxillofacial fractures account for 13.2% of all the fractures, only next to the lower limb (46.3%) and upper limb (24.7%) fractures. Recovery pattern of the infraorbital nerve sensory dermatome. [2], ORIF is the treatment of choice for mild to moderately displaced ZMC fractures, due to the desired functional and cosmetic outcomes achieved, as well as allowing early return to work after the surgery. official website and that any information you provide is encrypted The site is secure. The infraorbital nerve originates from the maxillary nerve, a branch of the trigeminal nerve, that runs along the inferior orbital fissure to reach the orbital cavity, and then passes through the infraorbital canal to come out of the infraorbital foramen and reaches the face [1]. Wolters Kluwer Health HHS Vulnerability Disclosure, Help Orbital floor fracture, also known as blowout fracture of the orbit. Feriani G, Hatanaka E, Torloni MR, da Silva EM. Patients willing to participate in the study. Depending on the cause of your pain, your pain specialist will decide whether or not to embark on physical treatment. Symptoms of nerve injury may be varied from paresthesia, numbness at the site of the nose, upper lip. Orbital tissue herniating into the sinus through the resulting defect in the orbital floor may become entrapped, causing diplopia and possible oculocardiac reflex; if the displacement of the bony fragment is large enough, enophthalmos may develop. may email you for journal alerts and information, but is committed HHS Vulnerability Disclosure, Help Factors that influence peripheral nerve regeneration: an electrophysiological study of the monkey median nerve. Thirteen patients diagnosed with unilateral ZMC fractures, having neurosensory deficits over the distribution of the infraorbital nerve were included. This case report observed a patient for 18 months and confirmed nerve function recovery following peripheral nerve regeneration in a patient with avulsion injury to the infraorbital nerve. 3/2/March-2019/PG-Thesis-HRD (5D)]. infraorbital nerve. This is usually temporary but can last up to 6 months or longer. Search for Similar Articles In the acute setting of midfacial trauma, a complete ophthalmologic examination is vital; in the event of a ruptured globe, retinal detachment, intraocular bleed, or other sight threatening complication, all orbital intervention should be postponed until the eye is stabilized. Robert H. Whitaker, Neil R. Borley. Epub 2021 Jun 25. Inclusion in an NLM database does not imply endorsement of, or agreement with, Frequency of infra-orbital nerve injury after a zygomaticomaxillary complex fracture and its functional recovery after open reduction and internal fixation. Arch Craniofac Surg. [2] Evaluation of neurosensory changes in the. ; Noor et al. The improvement at 3-month and 6-month postoperative follow-up was statistically significant at each site (P = 0.000), with 38.46% (n = 5) and 76.92% (n = 10) patients showing complete recovery, respectively [Figure 4]. The eye may be proptotic or enophthalmic, depending on the amount of edema (causing proptosis) and the size of the fracture (larger fractures leading to enophthalmos). The incidence of long-term deficits has been variably reported as from 10% to 50%. Further, multiple studies have shown that delaying surgery beyond two weeks is equally effective as earlier surgery, as long as all adhesions to the bony edges and to the sinus mucosa are lysed, the bony defect is completely exposed, and the implant is properly placed. One technique that may be useful in implant fixation is to use a few drops of a cyanoacrylate derivative (a superglue such as Histoacryl) just beneath the leading edge of the implant to cause adherence of the implant to the (dry) bone beneath it. Such treatment may help periorbital and extraocular muscle edema to subside more quickly to determine if the patients dysmotility is transient or if surgery is necessary. The anteroposterior view (A) and the worms-eye view (B) of the preoperative photographs. Blunt dissection can be performed in the eyelid atraumatically in the plane between the orbital septum and orbicularis muscle with a cotton tipped applicator down to the orbital rim, while the anterior lamella is simultaneously retracted with a DeMarres retractor. Prior to surgery, patients should also be reassured that recovery of extraocular muscle function will not be immediate, and that several weeks (and even a few months) may be required for full recovery to occur. Usually, by 3-4 weeks after the injury, a decision regarding surgery can be made with respect to disabling diplopia. All patients were assessed presurgically for neurosensory deficits of the infraorbital nerve using the various neurosensory tests, followed by open reduction with two-point fixation under general anaesthesia. Westermark A, Jensen J, Sindet-Pedersen S. Cho SE, Shin HS, Tak MS, Kang SG, Lee YS, Kim HS, Kim CH. Due to this nerve injury, patients complain of numbness and pain in the entire cheek, the ala of nose, and upper lip. The upper gingival mucosa receives sensory fibers from the trunk of the maxillary nerve as it runs towards the infraorbital canal. If you have nerve pain starting lyrica or neurontin or the like would be acceptable. The infraorbital nerve exits the infraorbital foramen, located immediately below the inferior border of the infraorbital ridge, and, via several branches, innervates the ipsilateral midface, lower lid, side of the nose, and upper lip. After analysing the results obtained from our study, it is observed that complete recovery of tactile sensation, pain sensation and spatial mechanoception was observed in the majority of the patients, and patients led an excellent QoL six months postoperatively, however, in some cases, a longer period of recovery may be required. Many patients with radiologic evidence of inferior rectus herniation do not have clinical entrapment, while many patients in whom orbital fat herniates into the defect, but where the inferior rectus muscle remains in the orbit, have severe dysmotility. Enophthalmos of the affected side may be present initially, but more commonly develops days to weeks after the injury as orbital swelling subsides. Rarely, if ever, is performing a forced duction test necessary or informative in making the diagnosis of extraocular muscle restriction in an awake patient with an orbital blowout fracture. Annals of Maxillofacial Surgery12(2):128-132, Jul-Dec 2022. and Tabrizi et al. With a peripheral nerve injury, you may experience symptoms that range from mild to seriously limiting your daily activities. Arch Craniofac Surg. There are also options for patient-specific implants that are custom made for each patient's fracture based on the defect seen on radiographic imaging[1]. Here, we present a case in which microsurgery was not performed in a patient with Sunderland grade V avulsion injury of the infraorbital nerve due to a facial bone fracture. Complaints such as scar tissue pain, herniated discs or neuropathic pain are discussed.

The complaints often resemble those caused by inflammation of the maxillary sinus. American Society of Anaesthesiologists (ASA) I and ASA II patients. [2,3] Infraorbital nerve damage can produce neurosensory disturbances such as hyperaesthesia, hypoaesthesia, paraesthesia, or anaesthesia of the structures innervated by the nerve including lower eyelid, cheek, the skin of lateral wall of the nose, upper lip and intraorally, the mucous membrane of the upper lip, cheek, and anterior as well as posterior teeth of the affected side. The avulsion injury of inferior orbital nerve was confirmed from the intraoperative finding. In the great majority of floor fractures, a fracture can be localized above, or just medial to, the course of the infraorbital nerve. At 3-month postoperative follow-up, improvement in QoL was noted, with 46.15% (n = 6) having satisfactory QoL; 23.08% (n = 3) having good QoL; and 30.77% (n = 4) having excellent QoL. Kumar P, Godhi S, Lall AB, Ram CS. The pain is sometimes triggered by shaving and is of the neuropathic type. This site needs JavaScript to work properly. Neural Regen Res. The improvement in the tactile sensation scores at 1-month postoperative follow-up was not statistically significant, with only 15.38% (n = 2) patients showing complete recovery, indicating the neurosensory deficits of the infraorbital nerve did not improve significantly. Unable to process the form. Prevention of an orbital floor fracture is only possible by preventing blunt trauma to the midface. However, some patients may continue to experience some long-term residual deficits, which can affect the patients QoL. Following the placement of the implant, a forced duction test can be performed to insure that no tissue is trapped beneath the implant.

This increase in bony pressure causes the weakest point in the orbit to buckle and crack, with the bone fragment thus created to be pushed inferiorly. The various neurosensory tests used were: two-point discrimination test [Figure 1]; tactile test [Figure 2] and pin prick test [Figure 3]. The anteroposterior view (A) and the worms-eye view (B) of the preoperative photographs. Immediately after an orbital floor fracture, the affected eye may have impaired motility, resulting in double vision. A 63-year-old man slipped and fell in a construction site and presented to the hospital with bilateral cheek swelling, left cheek numbness, and laceration wounds (Fig. Med J Armed Forces India 2014;70:325. 4.
