Objective To investigate a synthetical technique combining static and dynamic states for treating facial paralysis. Methods From October 1993 to November 2005, 93 patients (26 males, 67 females; aged 9-69 years; illness course, 6 months to 24 years) with facial paralysis were admitted for treatment, of whom 48 were unknown in their pathological origins, 32 had a history of intracranial or ear operation, 13 had their facial paralysis related to trauma. We applied synthetical techniques for treating facial paralysis, including denerved muscle (extensor hallucis brevis and extensor digitorum brevis) free graft using an operating or chemical technique, temporal muscular flap suspending, treatment of eye closure by uplifting zygomomalar tissues and temporal muscular flap suspending, brow lifting by the Buried Guiding Suture Appliance, Botox injection, and the nerve amputation of normal side for mandibular marginal ramus paralysis. Results After the treatment for 82 patients with the method of the denerved muscle free graft combining femporal muscular flap suspending, 3 patients with the method of uplifting zygomo-malar tissues combining temporalmuscular flap suspending for eye closure, 15 patients with the method of the Buried Giding Suture for eyebrow lifting, 4 patients with the Botox injection and nerve amputation of normal side for the mandibular marginal ramus paralysis,93 patientshad a good therapeutic result. The follow-up for 3 months to 10 years in all the patients revealed that 75 patients were satisfied with their treatment results and 13 patients were almost satisfied according to the criteria for the facialsymmetrical checking and the House-Brackmann grading system. The technique hadadvantages of a complete survival of the related small muscles, a hidden incision, less trauma for the Botox injection, and the denerved muscles for surrounding nerve inserting. Conclusion The synthetical technique combining static and dynamic states for treating facial paralysis is a good therapeutic method and the therapies for facial paralysis should vary with the different conditions of the paralysis. We advocate an individuation treatment for facial paralysis.
Objective To investigate the result of free vascular transplantation of denervated extensor digitorum brevis and extensor hallusis brevisfor the treatment of late facial paralysis. Methods From April 2003 to April 2005, 26 cases of facial paralyces were treated by transplantation of denervated extensor digitorum brevis and extensor hallusis brevis. During operation, the ends of the tendons were fixed at ala nasi, middle point of nasal labial fold,oral commisure and chin; the muscle belly were put around the masseter nerveto correct the nasal and oral deformity, microsurgery was applied to anastomosethe tarsus lateral vessels to the superficial temporalis vessels or the facial vessels. The result of the operation was evaluated by the Standard of Douglas Harrison and the Paresis Assessment scoring system of Stennert. Results The static appearance was satisfactory in 26 cases after operation, the bilateral oral commisure was symmetry and the dynamic appearance was greatly improved 6 months after operation. Among the 23 cases whose disease history was above 2 years，all could smile naturally and show their teeth symmetrically except 1 case whocould only move the oral commissure. Among the 3 cases whose disease history was less than 2 years, one could smile naturally and show his teeth symmetrically, one could smile but could not show his teeth symmetrically, another could move oral commissure but have no motion appearance. The result was evaluated as“” according to Standard of Douglas Harrison, accounting for 88% (23/26). Evaluated according to the Paresis Assessment scoring system of Stenert, the difference before operation and after operation was more than 5, accounting for 86% (22/26). Conclusion The free vascular transplantation of denervated extensor digitorum brevis and extensor halluces brevis can reconstruct the oral appearance for the treatment of late facial paralysis.
OBJECTIVE To explore a new surgical approach to repair facial paralysis in late stage, using regional transposition of pedicled sternocleidomastoid muscle for the dynamic reanimation of the paralyzed face. METHODS Seven cases with facial paralysis in late stage from December 1999 were treated and followed up for 10 months before clinical evaluation. In all of the cases, the sternal and clavicular branches of the sternocleidomastoid muscle were both elevated from their bony attachments, with the mastoid insertion left in situ as the pedicle for blood supply and accessory nerve maintained in it. The muscle strips were transposed and sutured to the orbicularis oris around the mouth corner on the paralyzed side. RESULTS Static asymmetry of nose and oral commissure on the paralyzed side were corrected immediately after operation, and the movement of the oral commissure recovered one week after operation. Symmetric smiling was observed in one month and all of the oral movements recovered in 10 months postoperatively. CONCLUSION The new approach to repair facial paralysis in late stage by regional transposition of pedicled sternocleidomastoid muscle is effective in restoration of both static and dynamic symmetry of nose and mouth, and in recovery of the facial expression and the oral commissure.
Using transplantation of free muscle with microneurovascular anastomosis for 46 cases of late facial paralysis, we selected M. latissimus dorsi as neurovascularized muscle bundle graft in 28 of them. This was not only an operation for facial dynamic reconstruction but also a new method for reinnervation of oral and ocular sphincter. After operation all of them revealed symmetry with voluntary motions. The results were satisfactory. The indications for surgical treatment, the procedure, and the management after the treatment were discussed in details. The importance of reeducation of the regenerating nerve and the necessity of twostaged operation were also discussed.
Objective To evaluate the therapeutic effect and complications of modified surgical treatment for parotid benign tumors. Methods Forty-nine patients with parotid tumors treated between February 2007 and February 2013 were randomly divided improved surgery group (trial group,n=24) and traditional surgery group (control group,n=25). Follow-up lasted from two months to two years after surgery. Postoperative complications (facial paralysis, Fery’s syndrome, local deformity, and salivary fistula) and recurrence were observed and compared between the two groups. Results All the 49 patients were followed up from two months to one year after surgery. Two years after surgery, three patients in the trial group and four in the control group were missing during the follow-up. No recurrence occurred in all the patients. There were no permanent facial paralysis cases in both groups. No temporary facial paralysis occurred in the trial group, while there were five such cases in the control group with an incidence rate of 20.0%. The trial group had one case of Fery’s syndrome with an incidence rate of 4.2%, and the control group had 4 such cases with an incidence rate of 16.0%. After surgery, the 24 patients in the trail group achieved general facial symmetry without any facial depression deformity, while there were 3 cases of mild facial depression and 1 obvious facial depression in the control group with an incidence rate of 16.0%. Five patients in the control group had saliva fistula with an incidence rate of 24.0% while one in the trail group (4.2%). The differences in the total rate of complications occurrence between the two groups were statistically significant (P<0.05). Conclusion The improved surgical treatment can effectively reduce complications after surgery for parotid benign tumors, which is worthy of clinical promotion.
