Background: To examine the feasibility and efficacy of weekly docetaxel with concurrent radiation as postoperative treatment in a multimodality approach to oral and oropharyngeal cancer.

Patients And Methods: 94 patients (Table 1) with primary resectable squamous cell carcinoma of the oral cavity and oropharynx (UICC stage I 14%, II 15%, III 18%, IV 53%; Table 2) were treated with a multimodality therapy program consisting of neoadjuvant intra-arterial high-dose chemotherapy (cisplatin 150 mg/m(2) with parallel systemic sodium thiosulfate 9 g/m(2) for neutralization), followed by surgery of the primary and neck, and postoperative concurrent radiation and chemotherapy with weekly docetaxel (20-30 mg/m(2); Table 3). Chronic toxicities were followed over a period of 5 years.

Purpose: To assess the impact of a diagnostic ladder including [(18)F]fluorodeoxyglucose positron emission tomography (PET) and lymphoscintigraphy guided sentinel node biopsy (LS/SNB) on neck treatment in patients with oral and oropharyngeal squamous cell carcinoma (OOSCC).

Patients And Methods: Prospectively, 62 patients with resectable T1-3 OOSCC underwent computed tomography (CT) and PET. Patients without neck uptake in PET were defined as cN0 and were accrued for LS/SNB.

Background: Speech and language acquisition are major, important criteria in the treatment outcomes of cleft lip and palate patients. A generally accepted and definitive treatment protocol regarding surgical techniques and the time schedule does not yet exist. In the world literature, there are reports of velo-pharyngeal insufficiency rates between 7 and 30%.

We describe a male patient with lobar holoprosencephaly, ectrodactyly, and cleft lip/palate, a syndrome which has been seen previously in only six patients. In addition, our patient developed hypernatraemia, which has been described in three patients before.

Background And Objective: The analysis of lateral cephalograms is based on many vague landmarks that vary intra- and inter-individually. Exposure to radiation and high-quality equipment are essential, while identical object positioning is almost impossible. Anthropometry as presented in the literature is time consuming and cannot reproduce cranial three-dimensionality.

The last part of this series outlines closure of the hard palate with various modifications depending on the remaining width of the cleft. Additionally the necessity and parameters of follow-up documentation are emphasized and detailed. For the two patients shown in Parts 1 and 2, the corresponding data are given.

Lip repair and synchronous columella lengthening in bilateral clefts of the lip, alveolus and palate following lip adhesion according to the method outlined in Part 1 is described in this part of the paper. Together with lip and nose repair the gingivo-periosteoplasty can also be performed when the alveolar process is perfectly aligned and the greater and lesser segments abutt onto each other.

The protruding premaxilla represents the most severe problem in the surgical closure of a bilateral cleft lip, alveolus and palate (BCLP). In principle there are two methods to overcome this obstacle: (1) preliminary lip adhesion and (2) presurgical repositioning with intraoral devices. According to the various degrees of premaxillary protrusion, sometimes adhesion alone is sufficient, if the surgical technique is unlikely to break down.
