Closure of Tracheoesophageal Puncture after Total Laryngectomy.

Tracheoesophageal puncture with voice prosthesis placement is used to restore vocal function after total laryngectomy. However, closure of the fistula is sometimes needed. At our department, a simple and effective technique for closure was developed. It does not require interposed tissues or materials. Moreover, our procedure allows for a short rehabilitation time for swallowing and a short hospitalization. We describe advantages, pitfalls, and errors to avoid. This technique should not be performed for patients who are irradiated and those with large fistulas.

Playing a brass instrument after total laryngectomy: a case report.

BACKGROUND: A brass instrument is a musical instrument in which the tone is produced by vibration of the lips as the player blows into a tubular resonator. The case of a professional brass player who continued his activity after total laryngectomy, with insertion of a voice prosthesis in a tracheoesophageal shunt, is reported. METHODS: A videoendoscopic and videofluoroscopic study of the patient during brass playing was conducted. RESULTS: A nonvibrating, open neoglottis during brass playing was found on videoendoscopy. Videofluorography revealed an enlarged hypopharynx, a thick neoglottis while playing at lower tone; at higher pitch the tongue base was retracted, the neoglottis was thin and stretched, and the subneoglottic area was extremely enlarged. CONCLUSION: The case reported shows that the insertion of a voice prosthesis in a tracheoesophageal shunt seems to create a regulating airflow system sufficiently advanced to play a brass instrument, further reducing the disability of laryngeal speakers.

Long-term voice and swallowing modifications after supracricoid laryngectomy: objective, subjective, and self-assessment data.

PURPOSE: The supracricoid laryngectomies (SCLs) are conservative surgical techniques for the treatment of selected laryngeal carcinomas. The advantage of SCL is that a permanent tracheostoma is not required, thus, maintaining the principal laryngeal functions. The aim of the study is to report objective, subjective, and self-assessment long-term results of voice and swallowing in a large group of patients who underwent SCL at least 2 years before this study was undertaken. METHODS: Twenty male subjects who underwent SCL with a mean age of 71 years (range, 51-82) were involved in a retrospective study on swallowing and vocal function. Videoendoscopic ratings were taken of neoglottic vibration patterns and bolus transit. The maximum phonation time and the syllable diadochokinesis were measured. Spectrograms were recorded. Voices were perceptually rated using the Grade, Instability, Roughness, Breathiness, Asthenicity, Strain (GIRBAS) scale. All of the subjects completed a self-assessment questionnaire for both voice and swallowing. RESULTS: Videoendoscopic ratings showed moderate to severe impairment of neoglottal vibration, whereas bolus transit appeared only mildly impaired. The mean values of the GIRBAS scale were 2.4, 2.6, 2.4, 0.8, 0.5, and 0.8. The mean maximum phonation time was 7.5 seconds, whereas the mean value of the Yanagihara scale was 3.7 for voice spectrograms. Mean syllable diadochokinesis appeared as 3.3 syllables per second. Voice and swallowing quality of life questionnaires revealed satisfied patients. CONCLUSIONS: Swallowing after SCL was satisfactory; on the contrary, endoscopic, aerodynamic, perceptual, and acoustic data showed a highly dysphonic voice after SCL. However, self-assessment results revealed relatively satisfied speakers on the emotional, physical, and functional levels.

Auditory steady-state responses and clinical applications.

The auditory steady-state responses to single continuous tones modulated in amplitude have been proposed as an alternative to objective frequency-specific audiometry. The aim of this study was to compare thresholds obtained by pure-tone audiometry (PTA) and by auditory steady-state responses in normal hearing or affected by hearing loss in adults and in order to evaluate the applicability of this objective test in no collaborative hearing-impaired subjects. Eleven people, 6 normal hearing and 5 with hearing loss, underwent PTA and multiple frequency auditory steady-state responses; simultaneous carrier tones (0.5, 1, 2 and 4 KHz) modulated in amplitude at different rates (77-105 Hz) were presented monaurally (TDH 49 earphones) at variable intensities (110-20 dB SPL). The mean threshold difference between PTA and multiple frequency auditory steady-state responses was 28 dB (standard deviation=14.2) and R correlation value at 0.5-1-2-4 kHz was 0.71 (P=0.0012) at the Pearson's test. These differences were significantly smaller considering the hearing-impaired separately (11.7 dB, standard deviation=2.9). The results of this study confirm previous reports showing that the multiple auditory steady-state response method is an accurate predictor of the behavioural audiogram in patients with sensory-neural hearing impairments and can be used as a valid support for behavioural evaluations.

Voice quality after carbon dioxide laser and conventional surgery for T1A glottic carcinoma.

The different types of small vocal fold tumor therapy allow the preservation of respiration and deglutition; the quality of phonation is the most important criterion for the patient. The aim of the study is to compare vocal function after treatment of T1a tumors by conventional and laser cordectomy. Fifty-seven male patients were included in the study: 27 underwent conventional cordectomy using an external approach, and 30 underwent an endoscopic microscopic laser cordectomy. Videolaryngoscopy was performed for each subject, and the maximal phonation time was measured. Spectrograms were recorded, and a perturbation analysis was performed if a clear harmonic structure was visible. Voices were perceptually rated by two experienced phoniatricians using the GRBAS scale. Even though a slightly better voice was found after conventional surgery throughout the data, no statistically significant difference was measured in the two groups. The data on voice outcome per se do not indicate the selection of one surgical approach over another.

13-cis retinoic acid in head and neck cancer chemoprevention: results of a randomized trial from the Italian Head and Neck Chemoprevention Study Group.

Patients with squamous cell carcinoma of the head and neck (HNSCC) after being treated radically remain at high risk for both recurrent and second primary tumours. 13-cis retinoic acid (13-cRA) was demonstrated to reverse pre-malignant lesions of the oral cavity and to reduce the incidence of second primary tumours in patients treated radically for HNSCC. Synergism between retinoids and interferon in tumoural cell lines have been demonstrated. Based on these data, the Italian Head and Neck Chemoprevention Study Group started a randomized chemoprevention study in patients radically treated for stage III and IV HNSCC. From February 1992 to January 1996, 267 patients were randomized: 126 were allocated to the control group, 126 were randomized to receive 13-cRA at a dose of 0.5 mg/kg per day per os and 15 patients have been assigned to the group of 13-cRA plus interferon alpha2a (IFN-alpha2a) at a dose of 3,000,000 UI 3 times a week (randomization in this arm interrupted due to administrative financial problems). The mean follow-up was 39 months. The 5-year actuarial survival was 58.9% for patients of the 13-cRA group and 57.2% for those of the control group (P=0.94). Among evaluable patients, disease progression was observed in 45 of 123 patients (36.6%) of the 13-cRA group and in 42 of 124 (33.9%) of the control group. The 5-year actuarial relapse-free survival was 48.9% for the 13-cRA group and 55.6% for the control group (P=0.62). Adverse effects, mostly of grade I were reported in 69.4% of treated patients (haematologic disorders, mucositis, conjunctivitis, cutaneous toxicity, hypertriglyceridemia and hypercholesterolemia). Only 5 patients (4.1%) reported grade III-IV toxicity. Low-dose of 13-cRA given for 1 year is ineffective as chemoprevention in patients with radically treated HNSCC.

Actinomycosis of the masseter muscle: report of a case and review of the literature.

A rare case of cervicofacial actinomycosis arising primarily in the masseter muscle is described. The patient was a healthy 74-year-old woman who was not immunocompromised and had no other primary pathological finding in the oral cavity. The importance of the differential diagnosis for this unusual infection is demonstrated with tumoral pathological findings. Possible predisposing factors as well as diagnostic and therapeutic methods are discussed.

beta-carotene supplementation in patients radically treated for stage I-II head and neck cancer: results of a randomized trial.

This study was aimed at evaluating the efficacy of beta-carotene in improving survival (S) and in disease-free survival (DFS) and reducing the incidence of second primary tumors (SPT) in patients with a radically treated stage I-II squamous head and neck tumors. Eligible patients were randomly allocated to receive beta-carotene (n=104) or no treatment (n=110). beta-carotene was administered at the dose of 75 mg/day for 3-month cycles within one month intercycle intervals for a 3-year period. The 3-year compliance to the beta-carotene was 68.7%. Only eight patients reported drug-related toxicity (7.8%). The median follow-up of all patients was 59 months. The median follow-up was 61 months (range 1-116 months) in the beta-carotene and 58 months (1-123 months) in the control group. The 10-year DFS was 75.7% for the patients in the beta-carotene and 74.3% for those in the control group (P=0.56). The 10-year S was 85.9% in the beta-carotene group and 80.9% in the control group (P=0.20). beta-carotene supplementation had no significant effect on the incidence of second primary tumors (RR=0.99; 95% C.I. 0.28-3.44). A statistically non-significant 40% reduction in the risk of death among subjects assigned to the beta-carotene compared to the controls was observed (RR=0.60; 95% C.I. 0.26-1.38). No increase in the death from cardiovascular diseases was observed among patients treated with beta-carotene. Our results might support the hypothesis that an adequate beta-carotene treatment could be potentially associated with a decreased risk of death in these patients.

Leiomyosarcoma of the larynx.

Leiomyosarcoma involving the larynx is extremely rare and may be difficult to diagnose. Because of the rarity of this tumor, little information exists on its long-term follow-up and optimal management. We present a review of the literature and report on a patient with leiomyosarcoma of the larynx treated with surgery and postoperative irradiation. In addition, the diagnosis and treatment of leiomyosarcoma are discussed. At six months' follow-up the patient showed no signs of local recurrence but had developed metastases to both lungs.
