A fracture through the roof of the maxillary sinus might result in sensory loss to the:
ExplanationThe upper incisor and canine teeth receive sensory innervation from the anterior superior alveolar nerve, which runs along the floor of the orbit. As the roof of the maxillary sinus abuts the floor of the orbit, a fracture here might result in a lesion in the anterior superior alveolar nerve.[br][br]The upper molar teeth receive sensory innervation from the posterior superior alveolar nerve, which does not run along the floor of the orbit and would therefore not be affected by a fracture through the roof of the maxillary sinus.
