# Odontogenic Sinusitis Presenting With Infraorbital Numbness and Progressive Maxillary Sinus Atelectasis

## TL;DR

A 55-year-old man with odontogenic sinusitis developed infraorbital numbness and chronic maxillary atelectasis, highlighting a rare clinical progression.

## Contribution

This case report presents a unique clinical progression linking odontogenic sinusitis to infraorbital neuropathy and maxillary atelectasis.

## Key findings

- Odontogenic sinusitis can present with infraorbital nerve neuropathy.
- Chronic maxillary atelectasis may develop as a progressive outcome.
- The case suggests a possible pathophysiological link between sinusitis and infraorbital neuropathy.

## Abstract

Odontogenic sinusitis is the most common cause of isolated maxillary sinusitis. Accurate diagnosis is important to ensure optimal treatment. We discuss the unique presentation of a 55-year-old man with odontogenic sinusitis and associated infraorbital nerve neuropathy. We document his later development of chronic maxillary atelectasis and discuss the possible underlying pathophysiology linking this with his infraorbital neuropathy.
