Quantitative analysis of facial palsy using a three-dimensional facial motion measurement system.
The prognosis for facial nerve palsy (FNP) depends on its severity. Currently, many clinicians use the Yanagihara, House-Brackmann, and/or Sunnybrook grading systems to assess FNP. Although these assessments are performed by experts, inter- and intra-observer disagreements have been demonstrated. The quantitative and objective analyses of the degree of FNP would be preferred to monitor functional changes and to plan and evaluate therapeutic interventions in patients with FNP. Numerous two-dimensional (2-D) assessments have been proposed, however, the limitations of 2-D assessment have been reported. The purpose of this study was to introduce a three-dimensional (3-D) image generation system for the analysis of facial nerve palsy (FNP) and to show the correlation between the severity of FNP assessed by this method and two conventional systems. ⋯ This objective method can produce consistent results that align with two conventional systems. Therefore, this method is ideally suited for use in a routine clinical setting.

Comparative StudyComparison of facial synkinesis at 6 and 12 months after the onset of peripheral facial nerve palsy.
To investigate the time course of synkinesis as a sequela of facial nerve palsy so that we are able to determine an appropriate time for deciding the outcome of recovery in patients with facial nerve palsy. ⋯ From our results, synkinesis deteriorated after the 6th month from the onset of palsy. Therefore, we should follow up the degree of synkinesis until at least the 12th month, and the outcome of recovery in patients with facial synkinesis should be evaluated at least 12 months after the onset.

Metastasis to submandibular glands in oral cavity cancers: Can we preserve the gland safely?
To analyze submandibular gland (SMG) involvement in cases of oral cavity cancers and decide whether to remove submandibular glands while performing neck dissections for oral cavity cancers to decrease the incidence of xerostomia, a common issue post-operatively. ⋯ Metastatic involvement of submandibular gland is extremely rare. Submandibular gland preservation, in the absence of evidence of gross contiguous involvement, does not affect survival. Hence, SMG can be safely spared during neck dissections for oral cavity squamous cell cancers except in certain situations such as close proximity of the primary lesion to gland, presence of intra-capsular lymph nodes in radiology, gross intraoperative evidence of invasion of the SMG and in salvage surgeries performed in post-irradiated and recurrent cases.
