Maxillary Nerve-Mediated Postseptoplasty Nasal Allodynia: A Case Report.

Endoscopic nasal septoplasty is a commonly performed otolaryngology procedure, not known to cause persistent postsurgical pain or hypersensitivity. Here, we discuss a unique case of persistent nasal pain that developed after a primary endoscopic septoplasty, which then progressed to marked mechanical and thermal allodynia following a revision septoplasty. Pain symptoms were found to be mediated by the maxillary division of the trigeminal nerve and resolved after percutaneous radiofrequency ablation (RFA) of bilateral maxillary nerves. To the best of our knowledge, this is the first report of maxillary nerve-mediated nasal allodynia after septoplasty.
