Familial corneal hypesthesia.

A 4-year-old boy with severe, diffuse, asymptomatic, punctate, epithelial corneal erosions had bilateral sharply decreased corneal sensation with normal skin sensation in the distribution of the trigeminal nerves. Subsequent family studies disclosed five family members with similar corneal changes and decreased corneal sensation and no punctate erosions. None had decreased skin sensation in the distribution of the fifth cranial nerve. No environmental factors or evidence of local or systemic disease accounted for these findings.

Enlargement of mandibular canal without hypesthesia caused by extranodal non-Hodgkin's lymphoma: a case report.

A rare condition of enlargement of the mandibular canal caused by an extra-nodal non-Hodgkin's lymphoma in a 59-year-old Japanese woman was reported. The patient had a swelling of the hard palate and protrusion of both ocular bulbs, which had been present for 10 years. A panoramic radiograph revealed that the right mandibular canal was widely enlarged, extending from the mandibular foramen to the mental foramen, without bone destruction. The continuous dilation of the mandibular canal to an approximate 15-mm width was associated with peripheral bony sclerosis. Computed tomography and magnetic resonance imaging showed a soft tissue tumor inside the mandibular canal. The lesion demonstrated expansive growth in the orbits, extending to the skull base through the superior orbital fissures and cavernous sinus. The lymphoma was suspected to have grown so slowly that the adjacent mandibular canal and ocular bulbs enlarged without destroying the normal bone and nervous tissue.

Infraorbital hypesthesia after maxillary sinus barotrauma.

We report a case of a diver who suffered an episode of maxillary sinus barotrauma that presented with decreased sensation over the cutaneous distribution of the infraorbital nerve after an ascent which produced facial pain and crepitus. This case illustrates a potential confusion between a decompression sickness etiology and a barotraumatic etiology for the observed sensory deficit. The clinical features of this case were most consistent with a barotraumatic etiology for the findings noted. The anatomy of the trigeminal nerve and previous reports of cranial nerve deficits following barotrauma are reviewed.
