Partial laryngectomy after irradiation failure.

INTRODUCTION: Radiation therapy is often the first method of treating patients with early cancer of the glottis. There is a substantial failure rate among these patients. Total laryngectomy has usually been the means of treating patients with failure after radiation. In recent decades, partial laryngectomy has been used for salvage in such patients. This article will discuss the use of partial laryngectomy for radiation failure both from the oncologic result as well as the morbidity. PATIENTS AND METHODS: Between 1984 and 1995, 27 patients with early-stage laryngeal carcinoma underwent salvage partial laryngectomy after irradiation failure. Vertical laryngectomy was performed in 18 patients (13 with T1 N0 and 5 with T2 N0) and horizontal-supraglottic laryngectomy in 9 patients (3 with T1 N0, 1 with T2 N0, and 5 with T2 N1). The mean follow-up was 4.1 years. RESULTS: Local control was obtained in 77.7% of patients with glottic lesions (T1: 84.6%; T2: 60%, P = NS) and in 55.5% of patients with supraglottic lesions (T1: 66.6%; T2: 50%; P = NS). There was no regional recurrence in the vertical laryngectomy group, whereas the regional control rate in the horizontal-supraglottic laryngectomy group was 77.7%. Distant control was achieved in 94.4% of patients with glottic disease and in 77.7% of patients with supraglottic disease. The overall survival rate for glottic lesions was 88.8% (T1: 92.3%; T2:80%; P = NS) versus 66.6% for supraglottic lesions (T1: 100%; T2: 50%; P = NS). CONCLUSION AND SIGNIFICANCE: Vertical laryngectomy was not associated with an increased complication rate. Morbidity in the horizontal-supraglottic laryngectomy group was higher, but a satisfactory functional outcome was obtained in all cases. Therefore, in early laryngeal cancer (glottic T1-T2, supraglottic T1) partial laryngectomy can be performed with good expectation of cure and satisfactory laryngeal function. In T2 supraglottic lesions, the oncologic results are less satisfactory; further research is required for developing more efficient complimentary or alternative treatments modalities.

Effect of perioperative immuno-enhanced enteral nutrition on inflammatory response, nutritional status, and outcomes in head and neck cancer patients undergoing major surgery.

Administration of imunno-enhanced nutritional support may decrease postoperative morbidity, mortality, and infectious complications in cancer patients. The aim of this study was to verify that perioperative enteral diet, enriched with the nutrients arginine, ribonucleic acid (RNA), and ω-3 fatty acids improves outcomes of head and neck cancer patients undergoing major surgery. Forty patients with squamous cell carcinoma of the head and neck were studied. Group 1 received no preoperative nutritional support, whereas Group 2 received an oral formula with nutrients arginine, RNA, and ω-3 fatty acids. After surgery, Group 1 received a standard enteral formula, whereas Group 2 received an enriched enteral formula. Albumin (g/dl), prealbumin, fibrinogen, CRP, Il-6, and TNFa were measured 5 days before and 8 days after surgery. No statistically significant difference was observed for all the evaluated markers between postoperative and preoperative levels for both groups. The rate of complications was significantly reduced in the total number of patients receiving immunonutrition and in the particular subgroup of well-nourished patients receiving an immuno-enhanced diet. Perioperative enteral immuno-enhanced feeding in head and neck cancer patients undergoing major surgery may influence the postoperative outcomes by reducing the frequency rate of infections and wound complications.

Modified supracricoid partial laryngectomy with cricohyoidopexy: Series report and analysis of results

Aiming to improve voice quality and to facilitate swallowing rehabilitation, we modified the supracricoid partial laryngectomy with cricohyoidopexy by preserving the posterior segment of the true vocal cord on the less involved side of the larynx. Between 1983 and 1994, 13 patients with supraglottic cancer were treated with this modified procedure. The possibility of incomplete tumor excision was eliminated by careful patient selection and intraoperative reconfirmation of tumor extent with frozen sections. Our results have been promising, with a 76.9% 3-year survival rate and a 69.2% laryngeal preservation rate. There were 7 recurrences, 3 local (2 at the superior border of the cricoid and 1 at the cricoarytenoid region) and 4 nodal, in 5 patients. Distant metastases developed in another patient. Three patients, 2 with local and nodal recurrence and 1 with distant metastases, died of disease. Functional outcomes were also good, with all patients achieving normal swallowing by the end of the first year, although 5 patients required temporary gastrostomy for transient swallowing impairment. Early decannulation and satisfactory voice quality were achieved in all cases. We believe that with proper patient selection this modified procedure is effective both for tumor control and for preserving a more functional larynx.

CO2 and KTP-532 laser cordectomy for bilateral vocal fold paralysis.

Laryngeal obstruction due to bilateral vocal fold paralysis has been treated in many different ways. The CO2 laser or KTP-532 laser endoscopic cordectomy described in this report is a slight modification of the posterior partial cordectomy proposed by Dennis and Kashima. This technique was used in 18 patients (14 with the CO2 and four with the KTP-532 laser). Prophylactic tracheostomy was performed pre-operatively. Post-operative results were excellent in nine cases, good in seven cases and poor in two cases who had to remain with a permanent tracheostomy tube with a speaking valve. The main complications noted were the formation of a granuloma (seven cases) and arytenoid oedema (six cases). Revision surgery was performed in the seven cases with granuloma formation and in the two with persistent oedema. The results and the post-operative findings from the use of the two lasers were similar.

Primary localized laryngeal amyloidosis presenting with hoarseness and dysphagia: a case report

IntroductionPrimary localized laryngeal amyloidosis is an extremely rare condition. It usually presents with hoarseness, pain and/or difficulty in breathing.Case presentationWe present the case of a 23-year-old woman with primary localized laryngeal amyloidosis who presented with hoarseness and dysphagia.ConclusionA search of PubMed shows that dysphagia in patients with laryngeal amyloidosis has been reported only once, although this symptom is relatively common in other conditions presenting with laryngeal mass. There were no signs of any systemic disease in our patient and diagnosis was established histopathologically. She was treated surgically by microlaryngoscopy under general anesthesia and the mass was excised using a CO2 laser technology method.

Supraglottic laryngectomy–series report and analysis of results

Between October 1987 and October 1993, 92 patients with squamous cell carcinoma of the supraglottis were treated by supraglottic laryngectomy and neck dissection in our department. There were 33 T1, 46 T2, six T3 and seven T4 cases. All patients with N+ necks and T3 or T4 tumours received post-operative radiotherapy (5,000-6,500 cGy). The patients were followed for a minimum of 36 months or until death. The incidence of local recurrence was 7.6 per cent. Neck recurrence was observed in 13 per cent of patients. Decannulation was achieved in 93.4 per cent of the cases with three patients undergoing gastrostomy because of aspiration. The average hospital stay was 26 days. The overall three-year survival was 83.6 per cent, with eight patients dying of unrelated causes. There was a significant difference in recurrence rate between patients in the N0 and the N+ stage.

Congenital aural atresia reconstruction: a surgical procedure with a long history.

BACKGROUND Pinna deformities, combined with congenital aural atresia, have been a matter of serious debate in the literature as they are associated with major aesthetic and functional problems that are difficult to manage. These problems have been described as early as 2000 BC. The aim of the present article is to approach the whole problem as one (pinna malformation and aural atresia) and present the history as well as the current approaches in reconstruction. METHODS Extensive literature search and medical history books were used as scientific sources. RESULTS For many centuries, the prevalent view was that any surgical attempts to reconstruct the pinna and the ear canal were of little value. In addition, the aesthetic result of these early surgical procedures was mostly unacceptable. Over time, new surgical techniques and synthetic materials were used, leading to satisfactory and lasting aesthetic and functional results in selected patients, improving their quality of life, while reducing the complication rate. However, many cases are still challenging for plastic surgeons and ENT surgeons alike. CONCLUSIONS Despite significant progress in the field, surgery for pinna deformities combined with congenital aural atresia still remains one of the most challenging and risky procedures. Accurate audiological evaluation of newborns as well as assessment of their craniofacial development is necessary and can help the plastic surgeons and otologists choose proper candidates for surgical repair and a suitable and age-appropriate therapeutic plan. History and repeated failures have taught us that close multidisciplinary approach is of paramount importance.

Resection of giant ethmoid osteoma with orbital and skull base extension followed by duraplasty

BackgroundOsteomas of ethmoid sinus are rare, especially when they involve anterior skull base and orbit, and lead to ophthalmologic and neurological symptoms.Case presentationThe present case describes a giant ethmoid osteoma. Patient symptoms and signs were exophthalmos and proptosis of the left eye, with progressive visual acuity impairment and visual fields defects. CT/MRI scanning demonstrated a huge osseous lesion of the left ethmoid sinus (6.5 cm × 5 cm × 2.2 cm), extending laterally in to the orbit and cranially up to the anterior skull base. Bilateral extensive polyposis was also found. Endoscopic and external techniques were combined to remove the lesion. Bilateral endoscopic polypectomy, anterior and posterior ethmoidectomy and middle meatus antrostomy were performed. Finally, the remaining part of the tumor was reached and dissected from the surrounding tissue via a minimally invasive Lynch incision around the left middle canthus. During surgery, CSF rhinorrhea was observed and leakage was grafted with fascia lata and coated with bio-glu. Postoperatively, symptoms disappeared. Eighteen months after surgery, the patient is still free of symptoms.ConclusionBefore management of ethmoid osteomas with intraorbital and skull base extension, a thorough neurological, ophthalmological and imaging evaluation is required, in order to define the bounders of the tumor, carefully survey the severity of symptoms and signs, and precisely plan the optimal treatment. The endoscopic procedure can constitute an important part of surgery undertaken for giant ethmoidal osteomas. In addition, surgeons always have to take into account a possible CSF leak and they have to be prepared to resolve it.

Isolated inverted papilloma of the sphenoid sinus.

Inverted papilloma is a rare benign sinonasal tumour, characterized by a potentially invasive nature. The lateral nasal wall represents the most common site of origin, whereas paranasal sinuses are quite frequently found to be involved by extension. In contrast, primary sinus inverted papillomas have rarely been reported. The present study describes an extremely rare case of inverted papilloma, isolated to the left sphenoid sinus, that was treated by a transnasal endoscopic procedure. The therapeutic approach chosen is discussed and the results of a two-year follow-up are also presented.

Stapedotomy in osteogenesis imperfecta patients.

Osteogenesis imperfecta (OI) is a connective tissue disorder characterized by osseous fragility, blue sclerae and hearing loss. In order to assess the impact of stapedotomy on improving hearing on OI, a retrospective, one-group, pre-test-post-test design was used to compare the pre-operative and post-operative audiograms of nine OI patients, treated with stapedotomy for their mixed hearing loss. Operative findings included fixation or thickening of the stapes footplate with normal superstructure configuration and hypervascularization of the promontory mucosa. Immediate post-operative results showed a significant improvement (p < 0.05) from 250-4000 Hz in air conduction and from 250-2000 Hz in bone conduction. A significant closure of the air-bone gap between 250-2000 Hz was also achieved (p < 0.05). The long-term results remained satisfactory with a mean threshold shift of 8 dB HL and an almost unchanged air-bone gap. These satisfactory results and the lack of complications make stapedotomy an appealing method for the management of OI-associated hearing loss.
