Specifications about the sizes of normal salivary glands are not available. We used ultrasonography to determine the sizes of the submandibular and parotid glands in 50 subjects, who were not suffering from diseases of the salivary glands. Volunteers were distributed equally concerning sex and age. Body weight did not differ more than 20% from ideal weight. Dimensions of the submandibular glands were: anterior-posterior length, 35 +/- 5.7 mm; paramandibular extension to gland depth, 14.3 +/- 5.7 mm; extension in frontal scanning, 33.7 +/- 5.4 mm. The parotid glands measured 46.3 +/- 7.7 mm in the axis parallel to the mandibular ramus and 37.4 +/- 5.6 mm in a transverse axis. The extensions of the parotid parenchyma were 7.4 +/- 1.7 mm lateral to the mandible and 22.8 +/- 3.6 mm dorsal to the mandible.

A case of nasal turbinate dislocation secondary to nasotracheal intubation is presented. Although mild epistaxis had occurred in the days following extubation, the complication was not recognized until after the patient presented with headache and impairment of nasal breathing 6 months later. Endoscopy revealed the dislocation of the middle turbinate into the nasopharynx. Treatment by resection of the dislodged turbinate resulted in relief of symptoms. Physicians should be aware of the possibility of severe nasal damage following even apparently uncomplicated intubation and obtain consultation by an otorhinolaryngologist after epistaxis or obstructed nasal breathing.

Total reconstruction of the auricle requires a skilful surgical technique and an appropriate material for the shape-supporting frame. Up to now, there is no such material apart from autologous rib cartilage. The combination of chronic microtraumatisation of adjacent tissue caused by the mobility of an implant bed such as the auricle and the foreign-body reaction to currently available artificial polymers frequently results in extrusion. In our animal model (rats), polymers of different elasticity were implanted in a moving implant bed to analyse differences in foreign-body reaction related to implant elasticity. The results were significantly better for a rather stiff control material (porous polyethylene). A contributing factor may be better fixation of the implant material by tissue ingrowth into its micropores.
