Clinical experience with Gore-Tex for vocal fold medialization.

OBJECTIVES/HYPOTHESIS: Present clinical experience with vocal fold medialization under local anesthesia using a Gore-Tex implant. The procedure consists of placing the implant into a pocket formed by dissection of the inner perichondrium of the thyroid cartilage through a small window made in the thyroid ala. STUDY DESIGN: During 2 years, we used this technique preferentially in 13 of the 16 cases of vocal fold medialization (three patients underwent Teflon injection because of a contraindication to local anesthesia). Follow-up was longer than 3 months in 11 cases (mean, 13 mo). METHODS: Vocal result was analyzed by the means of perceptual analysis and by the measurement of jitter factor. Glottal leakage was evaluated perceptually using videolaryngoscopy, and oral airflow was measured during the production of a vowel. In cases with preoperative aspiration, videofluoroscopy was performed. RESULTS: Implantation was successful in all but one patient in whom extrusion of the implant material occurred. In the latter case, the implant was removed and the patient recuperated his preoperative voice without any other complication. In the 10 other cases, voice improvement assessed by perceptual and objective evaluation was satisfactory. CONCLUSIONS: Results compare favorably with those of endoscopic techniques using Teflon or collagen and laryngeal frame surgery techniques using silicone or cartilage. We conclude that Gore-Tex implantation is a simple, reproducible, and minimally invasive procedure for management of selected cases of vocal fold unilateral paralysis in the abductory position.

Idiopathic temporal encephalocele: report of two cases.

BACKGROUND: Idiopathic brain herniation into the middle ear is a rare condition that represents diagnostic and therapeutic challenges. OBJECTIVE: The authors present here two new cases of idiopathic brain herniation with special clinical presentation and emphasis on radiographic studies, particularly computed tomographic scan and magnetic resonance imaging, which allowed the authors to detect the malformation. RESULTS: The two patients underwent surgical treatment with infratemporal approach and recovered perfectly.

[Extensive rhinectomy. Apropos of 7 cases].

We report our experience in reconstructive surgery after total rhinectomy. Reconstructive surgery is performed after large excision and negative marginal biopsy results. The three layers of the nose (mucosal, osteocartilagineous and cutaneous) are restored by mucosal and cutaneous flaps and osteocartilaginous grafts. Carcinologic and cosmetic results are satisfactory but functional results may yet be improved.

[Fixed mallear head syndrome].

Fixed head malleus syndrome is a rare anatomoclinical entity first described by Goodhill in 1966. We present a series of 9 patients who underwent surgery between 1991 and 1997 and discuss the technical procedures used and functional outcome. Ossicular mobility can be re-established with two surgical methods. The more simple method consists in a classical incus transposition with malleus neck section. The more physiological method consists in drilling the synostosis fixing the malleus without disrupting the ossicular chain; stapedotomy is associated in certain cases (Type III).

[Medialization of paralysed vocal cord by expansive polytetrafluoroethylene implant (Gore-Tex)].

We report a technique for medialization of a paralyzed vocal cord using a Gore-Tex (expanded polytetrafluoroethylene) implant inserted under local anesthesia via a cervical incision. Gore-Tex is an expanded form of Teflon. It is used in vascular surgery (vessel repair) and esthetic surgery (particularly to increase lip volume). In esthetic surgery, the development of inflammatory processes difficult to control have been observed with teflon and appear to be less frequent with Gore-Tex due to the absence of free particles in the expanded form. The minimally invasive technique is simple and reproducible and can be performed under local anesthesia. We report a series of 9 cases operated from October 1995 to October 1997. During this period, this technique predominated (two other patients had Teflon injections). Excepting one case of extrusion of the implant material, vocal results were very satisfactory, based on both subjective and objective analysis of vocal parameters. The contribution of this technique in comparison with the reference endoscopic techniques (Teflon, collagen) and surgical techniques (silicone, cartilage) is discussed. Early results would suggest that Gore-Tex implantation can be used in the more severe forms due to vocal cord paralysis in the lateral position.

[Laryngeal cancer in a young adult].

BACKGROUND: Carcinoma of the larynx is uncommon in young adults. Persistent dysphonia despite medical treatment is generally the primary manifestation. CASE REPORT: A 21-year-old woman with no known risk factors developed squamous cell carcinoma of the left vocal cord. Clinical cure was considered to be achieved 40 months after external radiotherapy. DISCUSSION: Clinicians should be aware of the possibility of carcinoma of the larnyx in young patients with no risk factors. Treatment should take into consideration not only the aggressive nature of these tumors but also the long-term side effects and the major functional and psychological sequelae.
