[Cervical branchiomeric paraganglioma. Report of 21 cases].

Over the last 24 years the authors operated 21 branchiomeric paragangliomas in 18 patients. They emphasize the difficulty of making the diagnosis and the importance of completing a thorough work-up before deciding surgery. Adequate imaging is particularly important (neck sonography, computed tomography, arteriography) to avoid making the diagnosis by exploratory neck dissection and to assess the vascular risk. Biological studies have regained importance, especially in the context of complex neuro-cristopathy. Treatment is essentially surgical and must be considered with prudence in patients with bilateral lesions. The surgical removal of branchiomeric paragangliomas necessitates preparation of a small saphenous vein bypass in case it is not possible to avoid sacrificing the internal carotid artery.

[Malignant cervical epithelial adenopathy from unknown primary source. Apropos of a series of 54 cases].

Fifty four patients with cervical lymph node metastasis from an unknown primary tumor underwent treatment from 1969 to 1988. Fourty five underwent radical neck dissection. 69% had node capsular effraction and 36% perinodal vascular embolism. Thirty four patients underwent postoperative radiotherapy including rhinopharynx, cervical oesophagus and all the bilateral cervical nodes. The primary tumor appeared after treatment in 7 cases. Total survival rate is 36% 5 years after treatment. Vascular embolism aggravates the prognosis. Radiosurgical association allow effective control of loco-regional cancer but does not improve survival rate. Prognosis is aggravated by metastases arising (18%).

[Selective laryngeal re-innervations in the dog by nervous microsutures of branches of the recurrent laryngeal nerve].

INTRODUCTION: This work has been carried out to investigate in an animal model, the possibility of surgical selective reinnervation of the larynx following destruction of the laryngeal branch of the vagus nerve. MATERIAL AND METHODS: In ten dogs, on the right side of the neck only, the recurrent laryngeal nerve was identified, cut and section of the nerve removed. Following this the hemi-larynx on the operated side was reinnervated in the following manner. Using a microsurgical suture (described in the text) the motor nerves from extra-laryngeal muscles were anastomosed onto the nerves supplying the intrinsic abductors and adductors of the larynx. The nerve to sterno-thyroid was anastomosed onto the nerve supplying the posterior crico-arytenoid muscle (vocal cord abductor). Similarly the nerve supplying thyrohyoid was anastomosed onto the cut distal end of the adductor division of the recurrent laryngeal nerve. Clinical, electromyographical and histological evaluations have been used to prove the reinnervation. RESULTS: In the nine surviving animals successful re-innervations, as defined by the return of normal function, has been achieved for posterior crico-arytenoid and 7 adductor muscles. CONCLUSION: This study has demonstrated the feasibility of laryngeal reinnervation after surgical section of the recurrent laryngeal nerve, and give some cause for optimism for its ultimate application in man.

[Retrospective study of the treatment of piriform sinus cancers. Apropos of 97 cases].

Results of a retrospective analysis of case-reports of 97 patients treated for piriform sinus cancer showed a high frequency of large tumors and adenopathies providing an explanation for the very poor prognosis of these cancers. Therapy of choice for T1-T2 tumors is still radiotherapy. However, recently obtained results and data from the literature demonstrate the increased benefits of partial surgery with monoblock curettage followed by radiotherapy in cases with an ulcerous tumor, a mobile larynx and adenopathy of 3 cm or more. For T3-T4 cases the best treatment is by total pharyngolaryngectomy and postoperative radiotherapy.

[Value of the pectoralis major musculocutaneous flap in the repair of the posterior wall of the pharynx and the lateral wall of the hypopharynx].

Two further indications for the use of a musculocutaneous flap from pectoralis major are reported: mucosal reconstruction after posterior pharyngectomy and vertical hemi-laryngopharyngectomy. This method was used in 7 cases, after previous surgery in 6 of these patients. Caution is necessary when interpreting carcinologic results because of the lack of long-term follow up results, but postoperative course was uncomplicated and tube removal and subnormal feeding was possible within 3 to 6 weeks.
