While most cases of paresthesia present immediately following trauma or intervention, delayed onset paresthesia represents a rare and poorly understood phenomenon that challenges both diagnosis and management.
The article “Delayed paresthesia of inferior alveolar nerve after dental surgery: case report and related pathophysiology” provides a compelling clinical case that highlights this unusual presentation, in which neurosensory disturbance developed days after a routine dental procedure.
This delayed manifestation contrasts with the typical immediate onset of nerve injury symptoms, emphasizing the need for clinicians to remain vigilant even in the absence of early postoperative complications.
From a pathophysiological perspective, the report explores potential mechanisms underlying delayed nerve dysfunction, including postoperative inflammation, edema-induced compression, hematoma formation, and secondary ischemic changes affecting neural conduction.
These processes may gradually impair nerve function, leading to sensory alterations such as numbness, tingling, or burning sensations in the lower lip and chin—areas innervated by the IAN.
Importantly, this case underscores the multifactorial etiology of IAN injuries in dentistry, which may arise not only from direct mechanical trauma but also from indirect biological responses following surgery.
The variability in onset and recovery patterns further complicates prognosis, although many cases of nerve injury demonstrate spontaneous improvement over time.
For dental professionals and students, this article serves as a valuable reminder of the complexity of neurosensory complications in oral surgery.
It reinforces the importance of thorough preoperative planning, careful surgical technique, and detailed postoperative monitoring, as well as clear patient communication regarding potential risks—even those that may present in a delayed manner.
👉 We invite dentists and healthcare professionals worldwide to read the full article in PDF to better understand the clinical presentation, diagnostic considerations, and biological mechanisms behind delayed IAN paresthesia—and to enhance patient safety in daily practice.
