Voice prostheses: long-term follow-up retrospective study (three- to sixteen-year follow-up of 22 patients).

BACKGROUND: Thirty-five patients using tracheoesophageal voice with a 3- to 16-year follow-up were investigated. We analyzed functional voice outcome, voice prosthesis (VP) lifespan, and VP-related complications. METHODS: Between 1987 and 2001, 81 patients underwent total laryngectomy (TL). The 35 currently surviving patients (31 men, 4 women) were studied for VP lifespan and VP-related complications encountered up to 16 years after surgery. For voice rehabilitation, the 35 laryngectomies of our study required 178 prostheses. Short- and long-term voice results of 22 patients were compared by objective voice examination: maximum phonation time (MPT), intensity range (Int.), fundamental frequency (F0), frequency analysis (FA), and voice handicap index (VHI). RESULTS: Long-term results are: F0=131 (range: 30-250); Int=22.5 dB (range: 17-35 dB); MPT=4 sec (range: 2-12 sec); FA=3 (range: 1-4); VHI=38/120 (range: 8-73). Short- vs long-term outcome comparison shows the following values: F0: 93 vs 135 Hz; Int: 25 vs 24 dB; FA: 1 vs 3; and MPT: 21 vs 4 sec. The mean VP lifespan is 165.5 days for Provox (range: 2 days-30 months); 143.5 days for Blom-Singer (range: 10 days-24 months); and 195 days for VoiceMaster (6-7 months). Postoperative complications involved 12 cases of periprosthetic leakage (6.74%); 31 granulomas (17.4%); 3 partial stenoses of the tracheoesophageal tract (1.6%); and 1 temporarily removed VP (0.5%). CONCLUSIONS: Complications are generally resolved during standard office-setting examination. The commercially available VPs are complementary, used according to the diverse characteristics of each VP

Medialization framework surgery for voice improvement after endoscopic cordectomy.

Seven dysphonic patients who had previously undergone total or extended cordectomy underwent laryngeal framework medialization. A minimum 6-month period between cordectomy and framework surgery was enforced to allow the vocal cord to scar and form a fibrous "neocord", to evaluate the voice recovery achieved by speech therapy alone and avoid the risk of operating on a patient with undiagnosed early recurrence. The operation is performed with fiberscopic control under general anesthesia. These operating conditions are required because undermining the fibrous tissue at the inner side of the thyroid ala is a lengthy and laborious procedure. This step is necessary to ensure easy placement of the implant. Caution must be taken to avoid tearing the fibrous tissue, with consequent risk of prosthesis extrusion. The cartilage window is left intact. Whereas cartilage implants remain indicated for minor gaps, we advocate Friedrich's implant for wider gaps. The vocal outcome revealed an increased median maximum phonation time from 5 s (range 2-12 s) to 7.5 s (range 3-23 s); a reduced phonation quotient from 516.5 ml/s (range 235-1000 ml/s) to 222 ml/s (range 146-595 ml/s); a slightly increased modal intensity from 61.5 dB (range 57-75 dB) to 67 dB (range 46-68 dB); an improved intensity range from 24.5 dB (range 16-36 dB) to 30 dB (range 16-62 dB); a steady fundamental frequency from 150 Hz (range 132-290) to 152 Hz (range 125-200); and an increased median spectral analysis class from 2 (range 1-3) to 3 (range 2-4). Subjectively, the patients noted that, throughout the day, phonation required less effort and induced less vocal fatigue

Transcanalicular diode laser assisted dacryocystorhinostomy.

AIM OF THE STUDY: To assess the validity of transcanalicular diode laser assisted dacryocystorhinostomy (TLADCR) in the treatment of distal obstruction of the lachrymal pathways. MATERIAL AND METHOD: Between June 1999 and February 2000, 29 TLADCR were performed in the ENT department on 26 patients. Surgical indications included chronic dacryocystitis in 19 cases and dacryostenosis in 10 cases. In all cases but one, the surgery was carried out under a standard general anesthetic. The diode laser was used with a power setting of 10 watts. RESULTS: Seventeen out of 29 TLADCR were regarded as having successful outcomes. 2 out of 29 TLADCR had a little persisting tearing regarded as non debilitating and much less than which was present preoperatively. In 10 out of 29 TLADCR, the procedure was deemed a failure. These failures included 4 out of the 10 primary dacryostenosis and 6 out of the 19 chronic dacryocystitis. Two patients refused further treatment. In the other 8, surgical revision was undertaken via the traditional endonasal approach. In 7 of these cases, the lachrymal system was full of purulent secretions. COMPLICATIONS: Two patients developed a partial stenosis of one canaliculus that was diagnosed during the surgical revision. Another patient had a small fistula between the canalicular system and the skin of the corner of the eye that disappeared after the revision surgery. In one other case, the superior canaliculus was cauterised by the denudated portion of a resculpted laser fibre. Two bicanalicular nasal stent required reinsertion. Three patients developed a granuloma around the stent. Four patients developed an episode of infection whilst the stent was still in situ. CONCLUSION: Transcanalicular diode laser assisted dacryocystorhinostomy (TLADCR) performed with a 600-micron contact fibre is a relatively simple, elegant and effective procedure when used in conjunction with nasal endoscopy, to treat distal obstruction of the lachrymal pathways. But, the cost, the high prevalence of minor complications and the currently higher reported failure rate would favour external or endonasal approaches over this approach

Transnasal endoscopic orbital decompression and Graves' ophtalmopathy.

AIM OF THE STUDY: To assess the validity and the limits of endoscopic endonasal orbital decompression for Graves' ophtalmopathy resistant to the medical theapy. MATERIAL AND PATIENTS: Between September 1994 and May 1998, 16 patients with Graves' ophtalmopathy resistant to the medical treatment underwent an orbital decompression transnasally. 27 orbits were decompressed. The surgery was bilateral in 11 patients. In the 5 remaining cases, the surgery was unilateral. It was carried out on the left side in 2 cases and on the right side in 3 cases. RESULTS: Preoperatively, the average visual acuity was 8/10. Postoperatively, the visual acuity was 9.5/10. The average preoperative exophtalmometry measurement was 25.04 mm and the average postoperative measurement was 21.83 mm. The average retrodisplacement was 3.17 mm (range: 2-8). Preoperatively, 3 patients had mild diplopia whereas 5 others had moderate to severe extraocular muscle dysfunction. Postoperatively, 6 patients had mild diplopia whereas 10 patients required squint surgery for moderate to severe extraocular muscle dysfunction. CONCLUSION: Endoscopic orbital decompression improve all the symptoms of Graves' ophtalmopathy but one: the extraocular muscle dysfunction. Its cardinal indication is the treatment of compressive optic neuropathy whereas this surgical approach provides an excellent control of the medial wall of the orbit and the orbital apex. But the average reduction of proptosis of 3.17 mm is not high enough to propose this approach alone for the treatment of disfiguring proptosis. In such cases, a 2 or 3 wall orbital decompression should be performed to get marked cosmetic and functional improvement. In all cases, the patient should be informed about the risk of postoperative diplopia

Conservation surgery for laryngeal and hypopharyngeal cancer

The charts of 173 patients treated by conservation laryngectomy and pharyngolaryngectomy were retrospectively reviewed. The patients treated by endoscopic laser resection were excluded of this study. Glottic carcinoma was diagnosed in 101 patients, supraglottic carcinoma in 44 patients, hypopharyngeal carcinoma in 24 patients and oropharyngeal carcinoma in 4 patients. The median follow-up period was 44 months, 84/101 glottic cancer, 34/44 supraglottic cancer, 23/24 hypopharyngeal cancer and 2/4 oropharyngeal cancer were staged as T1 and T2. A voice-sparing external approach was carried on in 20 patients with locally advanced tumor (T3-T4). At time of the last follow-up, 132 patients (77%) were alive when 41 patients (23%) died. Overall survival rates for patients treated for T1-T2 glottic cancer at 3, 5 and 10 years were 90, 90 and 78% respectively. Overall survival rates for patients treated for T1-T2 supralottic cancer at 3, 5 and 10 years were 73, 68 and 48% respectively. Overall survival rates for patients treated for T1-T2 hypopharyngeal cancer at 3 and 5 years were 74 and 37% respectively. The site of the primary tumor (glottic versus supraglottic or hypopharynx) showed significant impact on survival (P = 0.0025)). Regarding survival, T stage and N stage were not found statistically significant

Skull base cerebrospinal fluid fistula: a novel detection method based on two-dimensional electrophoresis

The detection of the presence of cerebrospinal fluid (CSF) in nasal secretions contaminated with blood and mucus remains a challenging clinical problem

Comparison between the Percutwist and the Ciaglia percutaneous tracheotomy techniques.

A prospective study was designed to compare two single-dilator percutaneous tracheotomy techniques, the Ciaglia BlueRhino and the Percutwist technique. One hundred and ninety adult patients were included, 166 with the BlueRhino, a conical shaped, flexible rubber dilator, and 24 with the Percutwist, a screw like dilating device. The procedure was performed under fiberscopy in the intensive care unit (ICU). Age, body mass index (BMI), indication for tracheotomy, surgical landmarks, duration of the procedure and surgical complications were recorded. Median age and indications were similar for the two groups. Dilation was successful in all patients. The mean time for surgery was shorter with the Ciaglia technique: 8 +/- 3 versus 12 +/- 5 min with the Percutwist technique (P = 0.004). There was no significant difference related to weight, BMI, duration of tracheotomy and complications between both groups. One posterior tracheal wall puncture was observed with the Ciaglia technique and four with the Percutwist technique. No serious complications were noted with either technique. The Percutwist technique represents an alternative to the more established Ciaglia BlueRhino technique. The Ciaglia technique is a safe and more rapid procedure for bedside tracheotomy
