Objective: Noma, or cancrum oris, is rare in developed countries. Surgeons are likely to encounter this disease only in the context of a medical mission. While it is tempting to approach noma sequelae as an oncologic resection, an understanding of the disease process will reveal that the challenge is quite different.

Background: Frontal sinus obliteration is indicated in trauma and frontal sinus disease. We present our experience with a modified technique of frontal sinus obliteration.

Methods: We reviewed the records of 17 patients who underwent frontal sinus obliteration with a combination of Tisseel fibrin glue (Baxter Healthcare Corporation, Deerfield, IL) and calvarial bone and describe our technique.

Purpose: Purpose one was to characterize the consistency of intra-limb hip/knee (H/K) coordination according to a measure of average coefficient of correspondence (ACC) across strides. Purpose two was to investigate H/K ACC validity and ability to discriminate pre-/post-treatment change in stroke survivors.

Methods: Five healthy controls and 32 chronic (>12 mos) stroke survivors were enrolled, and H/K ACC was calculated for both groups.

Background: The two-flap palatoplasty was described more than 30 years ago, but there are few reports of long-term results using this technique. There are also very few long-term series of a single method of palatoplasty from a single surgeon.

Methods: The authors reviewed the technique of the two-flap palatoplasty, with emphasis on the senior author's (K.

The results of craniofacial and orthognathic surgery have traditionally been monitored using lateral cephalometry. In the age of computed tomography (CT) and magnetic resonance imaging (MRI), newer methods of measuring surgical outcome have arisen. This has been further enhanced by the use of computer software to render CT images in a three-dimensional format.

We studied the effects of change of head position in the pitch plane on the ability to hold horizontal eccentric gaze in five patients with cerebellar disorders. All patient showed a change in the time constant of horizontal centripetal drift when the head was pitched forward or back. This result suggests that otolithic inputs can influence the neural integrator for horizontal eye movements and indicates the value of testing horizontal gaze holding in different head positions.
