The effect of tracheostomy on swallowing function in open partial horizontal laryngectomies: preliminary experience.

OBJECTIVE: Tracheostomy is required to ensure a safe airway in open partial horizontal laryngectomies. The presence of the tracheostomy tube can contribute to post-operative dysphagia. This study aimed to evaluate the effects of a circumferential tracheostomy technique on swallowing. METHODS: A retrospective study was conducted of patients who underwent open partial horizontal laryngectomies between April 2018 and June 2019. Patients were divided into two groups based on the tracheostomy technique: group 1 had two stitches from the inferior tracheal ring to the skin; group 2 had circumferential fixation of the trachea to the skin. Demographic information, surgical data, post-operative rehabilitation course and complication details were collected and analysed. RESULTS: Twenty-four patients were enrolled. Patients in group 2 had significant improvement in the initial phases of swallowing rehabilitation. CONCLUSION: Tracheostomy with anchorage of the trachea to the skin by circumferential stitches could allow early removal of the tracheal tube, with a better swallowing outcome.

Results of Early Versus Intermediate or Delayed Voice Therapy in Patients With Unilateral Vocal Fold Paralysis: Our Experience in 171 Patients.

OBJECTIVES: Vocal fold paralysis can have an important impact on a patient's quality of life. The goal of this study was to compare, in terms of vocal improvement and motility recovery, the post-vocal treatment results of our patients with unilateral vocal fold paralysis (UVFP) when treatment was started early (within 4 weeks from injury) versus intermediate (from 4 to 8 weeks) or delayed (at least 8 weeks after injury) treatment. STUDY DESIGN: An 11-year retrospective study of patients with UVFP who underwent multidimensional diagnostic-therapeutic assessment. METHODS: In total, 171 patients with UVFP were included in our study, divided into three groups who underwent early (first group), intermediate (second group), or delayed (third group) voice treatment. All patients underwent voice therapy based on forcible exercises supplemented by manipulations and maneuvers. RESULTS: Of the 171 patients with UVFP, 106 (62%) recovered vocal fold motility. Of these 106 patients, 51/78 (65%) were in the first group, 30/49 (61%) in the second group, and 25/44 (56%) in the third group. A significant (P < 0.0001) reduction in fundamental frequency (Fo) was present in the first group with a manifest improvement in the mean values of Jitter (Jitt%; P = 0.001), Shimmer (Shim%; P < 0.0001), and noise-to-harmonic ratio (NHR; P < 0.0001). A significant (P < 0.0001) reduction in Fo was found in the second group with a manifest improvement in Jitt% (P < 0.001), Shim% (P < 0.0001), and NHR (P < 0.0001). For the third group, no values were statistically significant apart from the improvement in NHR (P < 0.001). CONCLUSIONS: This study confirms the importance of early rehabilitation underlining the non-functional vocal recovery in patients who started treatment later than 8 weeks after injury.

Therapy of unilateral vocal fold paralysis with polydimethylsiloxane injection laryngoplasty: our experience.

The objective of this study was to document functional results and to compare objective and subjective voice measures after endoscopic laryngoplasty with injection of polydimethylsiloxane (PDMS) for the treatment of unilateral vocal fold paralysis, and to verify PDMS biocompatibility in vocal fold. The design used was a longitudinal prospective study. Fifteen patients with unilateral vocal fold paralysis underwent endoscopic injection of PDMS in general anesthesia. Accurate voice evaluation protocol (acoustic and aerodynamics analyses, GIRBAS [Grade, Instability, Roughness, Breathiness, Asthenia, and Strain] scale, videostrobolaryngoscopy, and Voice Handicap Index test) before, after surgery, and at follow-up time was performed. The median follow-up was 21.7 months (range, 6-35). Data obtained were statistically significant. All acoustic, aerodynamics, perceptive, and subjective evaluations showed a significant improvement. No complications due to PDMS were reported. Functional results were found comparable to framework surgery. Endoscopic injection laryngoplasty with PDMS is a safe and long-term option for treatment of unilateral vocal fold paralysis.

[Reconstructive subtotal laryngectomy in the treatment of laryngeal cancer]. / Le laringectomie sub-totali ricostruttive nel trattamento del cancro della laringe.

Surgical techniques of sub-total reconstructive laryngectomies can often prevent the serious impairment of total laryngectomy without having to relinquish oncological radicality. The aim of the present work has been to report on the experience in this field accrued in the ENT Department of the University of Modena from 1987 to 1992. During this period 54 subtotal laryngectomies were performed. Of these, 13 were crico-hyoido-epiglotto-pexies (C.H.E.P.) and the remaining 41 were crico-hyoido-pexies (C.H.P.). The criteria suggested in the literature was adopted for tumor evaluation, surgical indications and contraindications. All the patients had a follow-up of at least 2 years and 31 of them have had at least 5 years of follow-up. There were 9 deaths: 3 due to intervening illnesses, 2 from second primary tumors and 4 from tumor and/or node recurrences. The overall survival was 83.3% at 2 years and 77.6% at 5 years. Determinate survival (ruling out those who had died because of intervening illnesses) were 88.2% and 80%, respectively. There were 11 neoplastic repetitions of which 2 were of the primary tumor, 2 of the primary tumor plus cervical metastases, and 7 of cervical metastases alone. Recovery surgery was performed in 9 patients, 5 of whom are still alive and disease free. Functional recovery (respiration, deglutition) took place slightly earlier in C.H.E.P. than in C.H.P. but in both cases this could be shortened, particularly by introducing a rehabilitative protocol during the immediate post-operative period. In no case did it prove necessary to perform a total laryngectomy to avoid "ab ingestis" problems and only one patient has a permanent tracheostomy.

[Logopedic rehabilitation of laryngeal granulomas]. / La rieducazione logopedica dei granulomi laringei.

Posterior laryngeal granuloma is an infrequent pathology of multidisciplinary interest. Actually, its real prevalence is difficult to quantify because in some cases it is asymptomatic and in other instances it may either be reabsorbed or eliminated spontaneously. It is located at the vocal apophysis of the arytenoid or, less frequently, above it or on the laryngeal side of the arytenoid. The many etiologic factors (laryngeal intubation, gastro-esophageal refluxes, blunt trauma of the larynx, vocal dysfunction), sometimes concomitant and with the possible addition of enhancing circumstances (upper aerodigestive tract inflammation, naso-gastric tube, smoking and alcohol abuse), converge to a single pathogenetic mechanism: an ulceration of the mucosa and the pericondrium, sometimes complicated by an infection, which does not heal but instead produces a typical granulation tissue with capillaries oriented radially from the center of the lesion. Post intubation granulomas, extremely rare in children, are more frequent in females. It appears that there is no correlation with duration of intubation in that granulomas, can also occur after short general anesthesia. Idiopathic or contact granulomas are more frequent in the males. They are the result of vocal laryngeal hyperfunction, habitual throat clearing or cough-like throat clearing. Gastro-esophageal reflux of gastric juice, coughing or throat clearing may injure the mucosa. A blunt trauma of the larynx may cause a granuloma if the cartilage of the vocal process is exposed. Symptoms, when present, are dysphonia, tiredness during or after voicing, bolus, laryngeal unilateral pain, sensation of something in the throat which is mobile during breathing and swallowing, traces of blood in the expectoration. Therapeutic options are surgical, medical or logopedic. Surgery, although followed by frequent recurrences, is mandatory when the granuloma causes dispnea or if a pathologic essay is needed. Medical treatment aims at solving gastroesophageal reflux and/or inflammations of the district. Logopedic rehabilitation is the most successful therapy. Since January 1992 the Authors have been adopting the rehabilitation protocol planned by the French phoniatrician Brigitte Arnoux-Sindt for post-intubation granulomas, which, moreover, is utilyzed for all type of granulomas, including those arising during the early postoperative period after cordectomy. This protocol is analytically presented and discussed. In the cases of contact granulomas, and when there is concomitant vocal dysfunction, logopedic treatment is prolonged after granuloma dissapearance with some sessions aiming at restoring correct vocal behaviour. In all the ten patients rehabilitated up to now, granulomas disappeared after a mean of 16.3 sessions held twice a week. After several months of follow-up we had no recurrences. This clinical experience, while limited in number, seems to confirm the good results already reported in French Literature.

[The experience of early rehabilitation]. / Esperienze di riabilitazione precoce.

Functional laryngectomies permit a more or less ideal preservation of laryngeal functions whose recovery, especially in les conservative operations, occurs very slowly and depends on several conditions: post operative course, sensitivity and motility of the hypopharynx, patient's ability to restore swallowing mechanisms. The Authors relate their experience concerning use of a rehabilitative program partially based on the experiences of some French logopedic schools and partially original. They illustrate the steps and goals of this program which starts on the fifth post-operative day with respiration exercises immediately followed by eight days of exercises to re-establish arytenoid mobilization and swallowing movements. If deglutition is not completely recovered and important inhalation problems persist, the logopedic approach is integrated with surgical rehabilitation consisting of one or more injection of gax-collagen. It is possible to use the same surgical technique later, after hospital discharge, if a slight dysphagia is still present in spite of continuous logopedic rehabilitation. Voice restoration exercises are introduced in the last days of the hospital stay when the patient is tube-free and continues at the office or outpatient clinic for two or three times every week. Concerning removal priority (tracheotomy tube followed by nasogastric tube or vice versa), we propose a diversified strategy for each patient, depending on the anatomicofunctional postoperative situation. Up to now 25 patients have taken part in this rehabilitation program (14 cricohyoidopexy, 6 Cricohyoidoepiglottopexy, 5 supraglottic laryngectomies). The results with regard to the amount of time that nasogastric feeding as well as tracheal tube are kept and the length of the hospital stay, were compared to those ones of a similar number of consecutive cases operated at our institution (ENT Department of Modena University) before February 1990 but not rehabilitated. In the early rehabilitated group, we observe a quicker functional recovery with a shorter hospital stay (about a week).
