ABSTRACT
Total laryngectomy remains as an important treatment option in selected patients with laryngopharyngeal cancers, which inevitably sacrifices naturally produced voice. Much effort has been devoted to voice restoration for these laryngectomized patients. Several ways of voice rehabilitation after total laryngectomy have been developed and utilized thus far, including tracheoesophageal shunt speech, esophageal speech, pneumatic speech aid, and electrolarynx. Of these, tracheoesophageal shunt speech appears to be the most effective voice restoration method, while other trials might also be useful in special situations. Nevertheless, each method has its own unique mechanisms of voice production, thus has its advantages and drawbacks in clinical setting. In this review, we discuss the currently available management options for the rehabilitation of laryngectomized voice.

Objective:To study the characteristics of condylar path in the patients with severe dental attrition.Methods:Using D5A De nar fully adjustable articulator and the Pantronic recording system, the kinemat ic character of condylar paths of 15 patients with severe occlusal attrition was investigated. In addition, the effects of posterior condylar determinants on oc clusal rehabilitation were studied in 5 cases. Results: The mean intercondylar distance of the patients was (60.72?4.40) mm, and the immediate side shift (ISS) was 1.35 mm(right)and 1.24 mm(left),the progressive si de shift (PSS) were 14.65 degrees (right) and 17.11 degrees (left),respectively. The Pantronic protrusive condylar guidance (PRO) were 23.45 degrees (right) and 26.85 degrees (left); The Pantronic nonworking path (ORB) was 26.50 degrees and the Fisher angle was present between protrusive path and nonworking path. In th e 5 cases of occlusal rehabilitation ISS, PSS and Panotronic reproducibility ind ex (PRI) were decreased.Conclusion: Occlusal rehabilitation main ly affect ISS, PSS and PRI.
ABSTRACT
We analyzed early postoperative astigmatic changes, visual rehabilitation and complications with silicone intraocular lenses implanted through 3.2mm scleral pocket incision (group I. 68 eyes) and PMMA intraocular lenses implanted through 5.5mm scleral pocket incision(group 2. 103 eyes). Surgically induced astigmatism in group 1 was -0.17D at two days, -0.12D at one week, and -0.51D at two months. In group 2, it was -0.36D at two days, -0.46D at one week, and -0.72D at two months. There was a statistically significant difference between the two groups at 2 days and 1 week (p0.05). 0.5 or better uncorrected visual acuity in group I was 74% at 2 weeks, 87% at 2 months while in group 2, it was 69% at 2 weeks, and 77% at 2 months. Postoperative complication in group I were two cases of IOL decentration(2.9%), two cases of anterior capsule contraction (2.9%), three cases of anterior chamber inflammation (4.4%), and two cases of posterior capsule opacity (2.9%). In group two, it were one case of hyphema (1%), one case of wound dehiscence (1%) , one case of anterior chamber inflammation (1%), and seven cases of posterior capsule opacity (6.8%). Our results indicate the 3.2mm scleral tunnel incision (group 1) was associated with a lower surgically induce astigmatism at 2 days and 1 week, and 8 faster visual rehabilitation than 5.5mm scleral tunnel incision (group 2), but anterior chamber inflainmation, anterior capsule contraction and IOL decentrations were more frequently developed in group 1.
