Prosthetic supply of facial defects: long-term experience and retrospective analysis on 99 patients.

INTRODUCTION: Defects in the head region may be caused by tumour treatments, injuries, as well as congenital malformations. The restoration of these defects that can be performed through reconstructive plastic surgery and/or prosthetic surgery occupies a high priority in the physical and psychological rehabilitation of the patient. The present study reports on long-term experience in supply of facial prosthesis. MATERIALS AND METHODS: The medical records of 99 patients, who had been supplied with custom-made facial prostheses between 2001 and 2011, were evaluated retrospectively. RESULTS: There were 59 male (60%) and 40 (40%) female patients. The reason for prosthetic supplement was a tumour disease in 50 patients, congenital malformation in 39 patients, and trauma in 10 patients. Fifty-three patients were treated with ear prosthesis, twenty-seven patients were treated with eye prosthesis, and nineteen patients with nasal prosthesis. 82.8% of prosthetic supplies were designed as magnetic support prostheses. The most common complication was skin redness around the implants. 10% of patients suffered the loss of the osseointegrated implants. CONCLUSION: The osseointegrated titanium implants with magnet support provide a reliable attachment for prosthesis and constitute a promising alternative to surgical reconstruction of complex facial defects.

Epithetic nasal reconstruction for nasal carcinoma: retrospective analysis on 22 patients.

Advanced nasal cancers usually demand partial or total rhinectomy followed by radiotherapy. Reconstruction of the resulting defects can be achieved by means of reconstructive plastic surgery and/or epithetic surgery. The data of 22 patients who had been treated after nasal ablation by means of custom-made silicone nasal epithesis fixed by bone-anchored magnets between 2003 and 2014 were evaluated retrospectively. There were 15 male (68.2 %) and 7 (31.8 %) female patients. The most common etiology that led to epithetic rehabilitation was a squamous cell carcinoma in 16 patients. An operative revision was necessary in two patients due to screw loss. Twenty patients were still alive with no evidence of disease after minimum follow-up of 2 years (90.9 %). Epithetic rehabilitation after nasal ablation to treat nasal malignancies is an interesting alternative to plastic and reconstructive surgery. Bone-anchored fixation using magnets can achieve a stable epithetic fixation after nasal ablation necessitating, in numerous cases, additional adjuvant therapy like radiation.

Cancer of unknown primary (CUP) of the head and neck: retrospective analysis of 81 patients.

The treatment of patients with cervical lymph node metastases without detectable primary tumor remains an important challenge, until today, no standard therapy is available. The present study investigated the multimodal treatment of patients with head and neck CUP syndrome (HNCUP) and their follow-up retrospectively. 81 patients with cervical lymph node metastases without a primary tumor were treated at the Departments of Otorhinolaryngology as well as Radiotherapy and Radiation Oncology at the University of Saarland in Homburg, Germany in the period between 1991 and 2013. All patients received routine work-up consisting of CUP panendoscopy and imaging. Neck dissection was then performed in 77% of the patients. The most common histology was squamous cell carcinoma (80%). Ten percent of the patients had distant metastases. All patients underwent primary or adjuvant radiation therapy, or simultaneous radiochemotherapy. After a median follow-up of 3.5 years, the 5-year survival rate was 30%. There was a local recurrence that was known in 20/63 patients (31%) and distant metastases were documented in 19/61 M0 patients (31%). Higher grade late toxicity (grade 3-4) was observed in 12% of patients. Neck dissection and radiation therapy remains an integral part of HNCUP therapy, while the use of chemotherapy could be considered in selected cases. Prospective multicenter randomized trials would be necessary to identify the best target volume and to clarify the role of chemotherapy.

Laser surgery for Zenker's diverticulum: European combined study.

Surgical intervention is the gold standard of treatment for Zenker's diverticulum. The aim of this study was to examine the role of laser surgery in a large number of patients with this pathological entity. The data of 91 consecutive patients treated due to Zenker's diverticulum with the aid of CO2 laser in three institutions (Homburg/Saar and Marburg, Germany/Athens, Greece) during the last 10 years were retrospectively analyzed. Parameters examined were sex, age, preoperative symptoms, length of operation and complications, revision surgery necessity and degree of patient satisfaction. All patients had a minimum follow-up of one year. Dysphagia was the most common preoperative symptom (78 %). The most common minor complication was dental injury (6.6 %), but a serious complication in form of emphysema was observed in only two patients (2.2 %). A surgical revision was necessary in 8 (8.8 %) of the treated patients. The majority of treated patients was free of symptoms (86.8 %), or presented mild symptoms (9.9 %) one year after intervention, and only three patients (3.3 %) were dissatisfied. Our study shows that laser treatment of Zenker's diverticulum is an efficient operative technique associated with low complications rates and significant improvement of patients' symptoms in most of the examined cases.

Nd:YAG Laser Treatment for Extranasal Telangiectasias: A Retrospective Analysis of 38 Patients with Hereditary Hemorrhagic Telangiectasia and Review of the Literature.

BACKGROUND/AIMS: Extranasal telangiectasias are common amongst hereditary hemorrhagic telangiectasia (HHT) patients. Telangiectasias can be found at sites like the external nose, lips, oral cavity and fingers. Although not life threatening, they can be annoying for patients and lead to bleeding in some cases, necessitating treatment. METHODS: The data of 38 HHT patients treated for extranasal telangiectasias during a period of 10 years by means of Nd:YAG laser were retrospectively analyzed. RESULTS: The telangiectasias treated affected predominantly the tongue, facial skin and lips. During a minimum follow-up of 3 years, only 7 patients required a revision of surgery. CONCLUSION: This study shows that Nd:YAG laser constitutes a fast, safe and efficient therapeutic modality for the treatment of extranasal telangiectasias.

Retrospective analysis of laser vs other therapeutic modalities for laryngeal papillomatosis: European multicenter study.

PURPOSE: Laryngeal papillomatosis can be an aggressive and potentially life-threatening disease, affecting both children and adults. Local excision is the gold standard of treatment, but recurrences are frequently inevitable. The purpose of this study was to present the experience of three institutions with different therapeutic modalities and discuss them in relation with the relevant literature. METHODS: Sixty patients underwent papilloma resection during the last decade in three institutions (Homburg/Saar and Marburg, Germany and Athens,Greece). Patient data were retrospectively analyzed for therapeutic modalities applied, rate of complications and synechia formation, necessary operations and need for tracheostomy. RESULTS: Carbon dioxide laser therapy was the most common modality applied alone or combined with other treatment modalities. No major complication was observed, while glottic synechia was the most common minor complication in 5 (8.3%) patients. Of the patient cohort 55.6% required reoperation, while no patient required tracheostomy. CONCLUSIONS: Surgical debulking with or without adjuvant treatment remains the mainstay of treatment, which mainly aims to reduce the number and frequency of recurrences since no definitive curative therapy is known so far.

Transcervical extirpation of the submandibular gland: the University of Marburg experience.

Surgical excision of the submandibular gland is the treatment of choice for lesions affecting this gland. The data of 87 patients, who underwent a transcervical extirpation of the submandibular gland as a single operation over the past 10 years at a single institution in Germany, were available for analysis. Sialolithiasis (73.5%) was the most common reason leading to excision, followed by benign (18.5%) and malignant tumors (8%). Complications included temporary palsies of the marginal mandibular branch of the facial nerve (5.7%), the lingual nerve (5.7%), and the hypoglossal nerve (1.1%), and wound infections in the form of hematoma (3.4%) and seroma (1.1%).

Extracervical approaches to endoscopic thyroid surgery.

There is increasing demand for surgical procedures which avoid visible scars while maintaining optimal functional and ideal cosmetic results, without compromising the safety or effectiveness of the procedure. Endoscopic techniques have been adapted to abdominal and pelvic surgery and increasingly employed over the past three decades. Although hampered by the absence of a natural cavity, endoscopic techniques have been adapted to surgery in the neck for the past 15 years, particularly for the thyroid gland. While earlier attempts at endoscopic thyroid surgery were performed through incisions in or near the midline of the neck, recent techniques have been developed to place the incisions and endoscopic ports extracervically, or at least away from the midline region of the neck, rendering the cosmetic result more acceptable. Most of these approaches are through the axilla, breast, chest wall or a combination of approaches. Visualization of the thyroid and rate of complications with these approaches are equal to those attained with older endoscopic approaches. Careful patient selection is important for endoscopic surgery. Complications unique to the endoscopic approach are mostly related to insufflation of cervical tissues with pressurized CO(2).

Auricular reconstruction with polyethylene implants or silicone prosthesis: A single institution experience.

Auricular reconstruction is usually necessary in patients with congenital malformations, after traumatic ear amputations or in cases of neoplastic ear disease. Thirty-nine patients who underwent an auricular reconstruction with either silicon prosthesis (21 patients) or porous polyethylene (18 patients) between 2002 and 2013 were retrospectively analyzed at a tertiary academic institution. A total of 25 male und 14 female patients were included in the study. In all, 43 implants were installed in 39 patients. An implant failure was not observed in any of the examined groups. An operative revision was necessary in 5 patients in the silicon prosthesis group (N = 21) and in 4 patients in the porous polyethylene group (N = 18). The most common side effect in the porous polyethylene group was the formation of retroauricular adhesions in 11.1 % by postoperative scaring, while in the silicone prosthesis group 71.4 % of the patients presented with skin reactions around the titanium implants. Our study shows that both techniques are valuable and should be offered to patients in cases of auricular reconstruction due to the low rate of severe complications and the good functional results of both techniques.

Laser CO2 tonsillotomy versus argon plasma coagulation (APC) tonsillotomy: A retrospective study with 10-year follow-up.

INTRODUCTION: Tonsillotomy is increasingly gaining acceptance as the treatment for tonsillar hyperplasia resulting in obstructive symptoms. The aim of this study was to compare the long-term results of CO2 laser tonsillotomy with those of argon plasma coagulation (APC) tonsillotomy. METHODS: The data of 64 children, aged 2-10 years (mean 4.7 years), treated in the Department of Otolaryngology, Head and Neck Surgery, in Homburg, Germany with APC (36 patients) or CO2 laser (28 patients) for tonsillar hyperplasia between June 2004 and December 2004 were available for analysis. RESULTS: Forty-five (APC: 26 patients, CO2: 19 patients) of the 64 patients (70.3%) could be contacted and were available for follow-up in a telephone survey conducted 10 years after surgery. The mean operation time was 17 min (range 10-25 min) in the APC group and 23 min (range 13-32 min) in the CO2 group (p = 0.0003). No case of intra- or postoperative bleeding was documented. One minor intraoperative complication in the form of a superficial lip burn was documented in the APC group. During the minimum 10 years of follow-up, 1 patient treated with APC underwent a surgical revision because of tonsillar regrowth, whereas in the group of patients treated with CO2, no surgical revision was needed. Regarding the parents' assessment of their children's symptoms, 89.4% of the parents of the CO2 laser group and 84.6% of the parents of the APC group reported that the overall long-term operation results of their children to be "very satisfying." Regarding complications, the need for secondary tonsillectomy, and parents' satisfaction, no statistically significant differences were found. CONCLUSIONS: Both CO2 laser tonsillotomy and APC tonsillotomy are safe procedures leading to very satisfying results with respect to intra- and postoperative complications.

Combined therapy for epistaxis by hereditary hemorrhagic teleangiectasia: A 3-year follow up study on 45 patients.

Hereditary hemorrhagic telangiectasia (HHT) is a mutilating disease associated with the majority of patients with recurrent epistaxis episodes. The aim of this study was to present a single institution experience with patients treated for nasal epistaxis using a combination of Nd:YAG laser and argon plasma coagulation (APC) vs Nd:YAG laser alone, with a minimum follow-up of 3 years. 45 patients (21 men, 24 women) aged from 15 to 84 years with the diagnosis of HHT were treated in the Department of Otolaryngology, Head and Neck Surgery in Homburg/Saar between 10/2002 and 10/2012 because of epistaxis, using a combination of Nd:YAG laser and APC or Nd:YAG laser alone. The observation period ranged from 36 to 120 months. 15 patients were treated with Nd:YAG laser alone and 30 patients with combined Nd:YAG laser and APC. A revision was necessary in three patients (20%) in the Nd:YAG laser group and in nine (33.3%) patients in the combined group. The difference between revision rates after the two therapy forms was not statistically significant (p = 0.492). Bipolar coagulation was additionally applied in 33 patients. There was no statistically significant difference (p = 1.00) in revision rates between patients who were additionally treated with bipolar coagulation and those who did not receive bipolar coagulation as part of their treatment. No case of postoperative septal perforation was observed. Nd:YAG laser therapy remains an established option for treating treat epistaxis in HHT patients.

Pharmacotherapy for squamous-cell carcinoma of the head and neck.

INTRODUCTION: squamous-cell carcinoma of the head and neck (HNSCC) is one of the most common malignancies, the treatment of which constitutes a therapeutic challenge. AREAS COVERED: the purpose of this review is to provide an update on the pharmacotherapy for the treatment of HNSCC focusing mainly on molecular-targeted therapies. An overview of the different novel therapeutic agents that can selectively inhibit signaling pathways and receptors that are involved in the development and progression of cancer especially in HNSCC is presented. EXPERT OPINION: the treatment of HNSCC is traditionally based on surgery and radiotherapy for early-stage HNSCC; however, chemotherapy is no longer used only for palliation, and individualized patient treatment assisted by molecular-targeted therapies represents a future therapeutic challenge.

Chemotherapy and targeted therapy in adenoid cystic carcinoma of the head and neck: a review.

Adenoid cystic carcinoma (ACC) is an uncommon tumor usually arising in the head and neck region, mainly in the salivary glands. It demonstrates an indolent prolonged course and is characterized by perineural invasion. Primary treatment of local and locoregional disease consists mainly of surgery and/or irradiation. During follow-up these patients frequently develop local recurrences and distant metastases, especially in the lung, although long-term survival is possible. The role of chemotherapy in ACC is limited, and studies with only a limited number of patients are performed. In this article we review the literature on chemotherapy regimens, including monotherapy and combination chemotherapy schedules, as well as the new targeted therapies.

Relevance of oropharyngeal cancer lymph node metastases in the submandibular triangle and the posterior triangle apex.

BACKGROUND: Neck dissection of levels I and IIB is time consuming and can cause several comorbidities. The aim was to analyze whether levels I and IIB need to be dissected in patients with oropharyngeal cancer and clinical N0 or N+ neck. PATIENTS AND METHODS: A retrospective analysis of 77 patients with oropharyngeal cancer was carried out with evaluation of the incidence of neck node metastasis in levels I and IIB. RESULTS: None of the patients with cN0 neck had metastases in level I or IIB; 12.8% of the patients with cN+ neck had metastases in level I, 35.1% in level IIA and 25.6% had metastases in level IIB. CONCLUSION: Levels I and IIB should be dissected in cN+ neck in order to achieve maximal oncological safety. The preservation of levels I and IIB in cN0 neck seems to be justified in terms of improving functional results and concomitant reduction of operation time.
