“…As the damage of the greater palatal and nasopalatine nerve and blood supply was excluded, the palatal mucosa necrosis that appeared after implant extraction could be explained by the contraction of smooth muscle within the arterial wall during the neurovascular bundle constriction that leads to transient ischemia of structures and tissue necrosis [28]. However, the definite terms of the necrosis manifestation are still unclear.…”

Dental implant failure in the anterior maxilla can be caused by the range of the features. One of them is neighboring neurovascular structure damage, such as the canalis sinuosus (CS), that carries the superior anterior alveolar nerve. The aim of the report is to demonstrate clinical symptomatology and radiographic signs of CS damage in a 45-year-old female patient who underwent upper left lateral incisor extraction and immediate implant placement and implant removal in 16 days secondary to pain and paresthesia in the maxillary left region.

Rationale: In dentistry, the most common procedure to be applied is administration of a local anaesthetic agent. It is impossible to practice dentistry without local anaesthesia. In the oral cavity, the palatal mucosa is tightly adherent to the palatal bone and there is little space for anaesthetic solution to be deposited. If local anaesthetic is forcefully injected by the syringe, it creates pressure on blood vessels and causes palatal necrosis. Patient Concern: Here, we present a case report of a 25-year-old male patient who reported to us with chief complaint of an ulcer on the palate. Diagnosis: Patient was diagnosed with postanaesthetic aseptic palatal necrosis. Intervention: The patient was managed conservatively using copious irrigation and a palatal acrylic splint. Outcome: On the 6 th month follow-up, the lesion was completely replaced by healthy mucosa. Take-away Lessons: We should avoid forceful injection of local anaesthetic agent to prevent further postoperative complications.

“…The contraction of smooth muscle within the arterial wall during vasoconstriction may lead to transient ischemia of structures distally to the injection site leading to tissue necrosis. [ 7 ] Furthermore, vasoconstrictors in local anesthetics reduce the oxygen supply to the injected tissue and promote the buildup of acidic by-products of metabolism. In addition, local anesthetic solutions with vasoconstrictors are adjusted to a lower pH to preserve the vasoconstrictors which however accentuate tissue acidity.…”

Palatal perforation: A rare complication of postanesthetic necrosis

et al. 2017

The everyday practice of dentistry relies heavily on achieving adequate local anesthesia. Even though the safety record of local anesthetic agents is high, complications do occur. Palate is a favorable site for soft-tissue lesions. Various factors such as direct effects of the drug, blanching of the tissues during injection, relatively poor blood supply, and reactivation of the latent forms of herpes can all promote to tissue ischemia and a lesion in the palate. Among various complications, anesthetic necrotic ulcer is a rare and uncommon condition occurring mostly in the hard palate possibly after a local anesthetic infiltration. The ulceration is often deep and shows spontaneous but delayed healing. If proper treatment is not instituted on time, the necrosis can reach deep into the bone causing sequestrum formation and ultimately leading to palatal perforation. Here, we report a case of palatal perforation in a male patient followed by surgical interventions and follow-up.
