Osseous expansion of the cranial vault by craniotasis.

A study of cranial vault lengthening using a custom expandable fixation-distraction (craniotatic) appliance was performed in the young-adult rabbit model. Ten 24-week-old rabbits underwent circumferential suturectomy plus expansion (expanded group), 10 underwent circumferential suturectomy without expansion (sham control group), and 10 served as normal controls. The appliance was lengthened at a rate of 2.5 mm per week for 5 weeks. Serial lateral cephalometry, comparative dry-skull anthropometric measurements, and histologic examinations were performed. The expanded group demonstrated a significantly longer skull, cranial vault, anterior cranial base, posterior face, and orbit as compared with the control groups (p less than 0.05). Callus bone filled the distracted suturectomy and united the frontofacial complex to the posterior cranium. In conclusion, skull lengthening by distraction osteogenesis is possible in the rabbit model and offers a new technique for future investigation in the treatment of coronal synostosis.

The crocodile tear syndrome.

Gusto-lacrimation, or "crocodile tear syndrome," is a rare complication, with 95 cases reported in the literature. Two patients are presented here, one after a facial fracture which apparently extended into the temporal bone proximal to the optic ganglion, and one after a Bell's palsy. The mechanism appears to be a misdirection of regenerating gustatory fibers destined for the salivary glands, so that they become secretory fibers to the lacrimal gland and cause homolateral tearing while the patient is eating. A simple procedure, involving subtotal resection of the palpebral lobe of the involved lacrimal gland, proved to be an effective corrective measure in these cases. Although it was not done in these cases, it would perhaps be advisable to do a Schirmer's test to assist in determining the amount of gland to be removed.

Ferris Smith.

Important events and renowned persons are seen and remembered differently by those who live the happening or know the person. In As I Remember Ferris Smith, four of his trainees provide a kaleidoscopic view of the doyen.
