Prosthetic voice rehabilitation after laryngoesophagectomy: surgical and functional outcomes.

PURPOSE: Quality of Life (QoL) after extensive head and neck resections is of paramount importance, especially after pharyngolaryngectomy or pharyngolaryngoesophagectomy where complex digestive tract reconstruction is required (with gastric pull-up or colon transposition). Tracheodigestive puncture (TDP) is the only vocal restoration option in this group of patients. The aim of this study is to evaluate postoperative complications, vocal outcomes, voice-related and swallowing-related QoL after secondary TDP in this cohort of patients. METHODS: A retrospective study was conducted in the tertiary referral center of Verona Hospital between June 2014 and June 2020. Patient demographics, clinical and surgical data were assessed. Speech objective and subjective evaluation was performed. QoL was assessed with Voice Handicap Index-10 (VHI-10) and M.D. Anderson Dysphagia Inventory (MDADI) questionnaires. RESULTS: Seven patients met the inclusion criteria, but two had died before questionnaires were administered. No intraoperative complications were noted after TDP surgery. There were delayed complications in four cases (57.1%) and all were treated with restoration. Intelligible voice was restored in all patients. Maximum phonation time and maximal voice intensity recorded were 5.42 ± 3.27 s and 65.20 ± 5.45 dB, respectively. Acceptable average VHI-10 and MDADI scores were obtained in all patients. CONCLUSIONS: Secondary TDP performed after gastric pull-up or colon transposition reconstructions are feasible and effective procedures. An intelligible voice was restored in all patients, with satisfactory patient-perceived voice-related and dysphagia-related quality-of-life outcomes.

Secondary tracheoesophageal puncture with the blind technique: 10 years' experience.

PROPOSE: The aim of the present article is to propose an alternative technique to the traditional secondary tracheoesophageal puncture (TEP) for voice rehabilitation after total laryngectomy, describing the procedure step-by-step, analyzing the complications and long-term results. METHODS: A retrospective study was conducted on patients who underwent secondary TEP with the blind technique using a rigid hysterometer. The main steps in this technique are described and illustrated. Patient demographics and surgical outcomes were assessed. RESULTS: Thirty-two patients were enrolled in this study. In all but one case, risk factors that could hinder rigid esophagoscopy were identified (37.5% neopharyngeal/esophageal post-surgical issues, 81.3% prior radiotherapy, 21.9% cervical arthrosis, and 12.5% prior coloplasty or gastric transposition). No intra- or postoperative surgical complications were noted. CONCLUSION: The blind technique offers an alternative method to perform a secondary TEP safely and efficiently in patients with unfavorable anatomical or clinical conditions, lowering the risk of procedure-related complications.

Botulinum toxin type A: an effective treatment to restore phonation in laryngectomized patients unable to voice.

We evaluated the efficacy of Botulinum toxin type A (BTXA) as an alternative to surgical intervention to facilitate phonation in 34 laryngectomized patients (31 males and 3 women) who were unable to produce tracheoesophageal voice because of spasm of the middle and inferior pharyngeal constrictor muscles (PCM). EMG was recorded to confirm activity in these muscles during attempted vocalization. Parapharyngeal nerve block (Carbocaine 2%, 5 cc) was used to demonstrate short-term fluent voice after relaxation of the pharyngeal constrictor muscle. At a later occasion, 100 U of Botox (Allergan) in ten patients and 50 U in two patients were injected unilaterally at one location in the PCM percutaneously under EMG guidance. All patients then underwent a voice therapy program. In 11 out of 12 patients an improvement of phonation was evident after 24-48 h and it was long lasting. This result was also seen in a patient previously myotomized without improvement. Only one patient needed to be reinjected every 3 months. At a follow-up after 3 months the EMG recorded in four patients showed a low-amplitude or complete absence of activity in the treated muscle. No side effects developed. BTX therapy, especially when associated with the speech therapy, is efficacious in restoring voice to laryngectomees who are unable to voice because of spasm of the PCMs. Our results confirm previous reports. This method is our approach of choice in managing PCM spasm because it is non-invasive, not painful, has few or no side effects, and is frequently long-lasting.

Secondary tracheoesophageal puncture: blind technique with a rigid hysterometer.

OBJECTIVES/HYPOTHESIS: The use of a rigid esophagoscope during tracheoesophageal puncture for speaking valve insertion in laryngectomized patients may be hindered by stenosis of the esophagus, or arthritic deformation of the spine, limiting extension of the neck. To prevent complications we currently perform a blind technique in these patients with the use of a rigid hysterometer instead of the esophagoscope. METHODS: Ten patients underwent secondary tracheoesophageal puncture using a rigid hysterometer. This was inserted through the mouth and gently advanced along the cervical esophagus to the level of the tracheostomy. A transverse incision was made on the posterior membranaceous wall of the trachea to enable the hysterometer to enter the tracheal lumen. The curved cannula of a Provox trocar was retrogradely inserted into the fistula following the hysterometer as a guide. After withdrawing the hysterometer, a Provox flexible guidewire was introduced into the cannula and advanced up to the oral cavity to anchor a Blom-Singer prosthesis. Withdrawal of the guidewire enabled the prosthesis to be housed in the fistula. RESULTS: All patients had a successful surgical outcome without any intra- or postoperative complications. The resulting fistula was adequate and enabled patients to wear their prostheses without trouble and to quickly acquire an intelligible voice. CONCLUSIONS: The limited thickness allows easy advance of the hysterometer beyond esophageal stenotic tracts, and its particular curved conformation permits progression toward the level of the tracheostomy in patients who cannot assume a relaxed, extended supine position on the operating table.
