Localization and treatment of lingual venous and arteriovenous malformations.

Venous and arteriovenous malformations of the tongue can cause haemorrhage, airway obstruction, difficulties in chewing and swallowing, speech problems as well as orthodontic abnormalities. The purpose of the present study was to evaluate their exact topography, clinical features, morphologic aspects and management. A retrospective review on all patients with venous and arteriovenous malformations of the tongue who presented between 1998 and 2010 was performed.

Visualisation of the Bonebridge by means of CT and CBCT.

Background: With the Bonebridge, a new bone-anchored hearing aid has been available since March 2012. The objective of the study was to analyse the visualisation of the implant itself as well as its impact on the representation of the bony structures of the petrosal bone in CT, MRI and cone beam CT (CBCT).

Methods: The Bonebridge was implanted unilaterally in two completely prepared human heads.

Localization of lymphatic malformations of the neck.

Background: The head and neck region is the most common site for lymphatic malformations. The aim of the present study was to analyze the exact localizations of lymphatic malformations of the neck.

Methods And Results: The patients' charts of 48 patients with lymphatic malformations of the neck were retrospectively analyzed regarding gender, age at diagnosis, age at initial presentation, morphologic type, size, and localization.

Incurable recurrences in patients with oropharyngeal and hypopharyngeal carcinomas.

Background: Carcinomas of the oropharyngeal and hypopharynx are difficult to treat because of their aggressive tendency to metastasize and their high recurrence rate.

Methods: A retrospective review of 79 patients with recurrences of oropharyngeal or hypopharyngeal carcinomas was performed. The courses of disease from recurrence diagnosis to the valuation date or death were analyzed.

Lymphatic malformations of the orbit.

Objectives: Lymphatic malformations of the orbit are rare lesions that constitute approximately 1% to 8% of all orbital masses. They are difficult to treat since they do not remain within anatomic boundaries and tend to penetrate into normal orbital structures. The aim was to analyze clinical courses and therapy options in patients with lymphatic malformations of the orbit.

Interstitial HDR brachytherapy for advanced recurrent squamous cell carcinoma of the head and neck.

Background: Surgical treatment remains the mainstay therapy for recurrence of head and neck cancer after previous radiotherapy. In inoperable cases, interstitial high-dose rate brachytherapy is a treatment option for local dose escalation.

Patients And Methods: A retrospective analysis of all patients who were treated solely with brachytherapy for advanced non-resectable recurrences of squamous cell carcinomas of the head and neck and who previously received radiotherapy was performed.

Risk of lymph node metastases after en bloc cold steel, en bloc laser-, and piecemeal laser surgical resection of auricular VX2 carcinoma.

There is some controversy in the literature if lymph vessels are enduring sealed during piecemeal CO2 laser surgery of squamous cell carcinomas of the head and neck or a propagation of tumor cells into the lymphatics occurs. The aim of the present study was to analyze the incidence of lymph node and distant metastases after different methods of resection of a VX2 carcinoma in an animal model. A solid auricular VX2 carcinoma was induced in 200 rabbits.

Age-dependent differences of the anterior skull base.

Objective: Imaging of the anterior skull base and paranasal sinuses is essential before surgery of the nose and paranasal sinuses. It is important to know individual anatomical variations to define a "dangerous ethmoid" to prevent complications such as considerable bleeding or injury to the brain. This study aimed to analyze the relevant parameters with special regard to age-dependent differences.

Prevalence of level V metastases in node-positive head and neck squamous cell carcinoma.

Background: The dissection of level V neck lymph nodes often results in a decline of postoperative quality of life due to shoulder dysfunction and pain. The necessity of level V dissection is debatable. The aim of the present study was to evaluate the prevalence of level V metastases in patients with node-positive squamous cell carcinomas of the head and neck.

Sclerotherapy of lymphangiomas of the head and neck.

Lymphangiomas are congenital malformations of the lymphatic system that consist of cysts of varying size. Although they are benign, they can undergo progressive growth with compression and infiltration of adjacent structures. Surgical excision has been the cornerstone of treatment, although total excision of the lymphangioma can be a major challenge and may be associated with severe complications.

Microcystic lymphatic malformations of the tongue: diagnosis, classification, and treatment.

Objective: To describe a classification of microcystic lymphatic malformations of the tongue and to investigate different treatment methods.

Design: Retrospective review of patients treated for microcystic lymphatic malformations of the tongue. Lymphatic malformations were classified into the following 4 groups according to their extent: isolated superficial microcystic lymphatic malformations of the tongue (stage I); isolated lymphatic malformations of the tongue with muscle involvement (stage II; stage IIA, involving a part of the tongue; stage IIB, involving the entire tongue); microcystic lymphatic malformations of the tongue and the floor of mouth (stage III); and extensive microcystic lymphatic malformations involving the tongue, floor of mouth, and further cervical structures (stage IV).

Polysomnography outcomes following transoral CO2 laser microsurgery in pediatric patients with laryngomalacia.

Objective: Laryngomalacia is the most common cause of stridor in newborns and infants. The aim of the contribution was to present objectified data of the outcome of transoral CO(2) laser microsurgery in patients with laryngomalacia utilizing polysomnography (PSG).

Patients And Methods: This retrospective study comprised 21 patients who were diagnosed to suffer from laryngomalacia.

Evaluation of children with lymphatic malformations of the head and neck using the Cologne Disease Score.

Objectives: To assess the disease-related impairments of children with lymphatic malformations of the head and neck and their changes after therapy using the Cologne Disease Score (CDS).

Methods: 29 children with lymphatic malformations of the head and neck were evaluated regarding their symptoms before and after therapy using the CDS. The Wilcoxon test for dependent groups was used to compare the CDS at initial visit before treatment and last visit after treatment.
