Autosomal dominant duplication of the renal collecting system, hearing loss, and external ear anomalies: a new syndrome?

We report two families in which propositi had severe bilateral sensorineural hearing loss, a preauricular pit or tag, and duplication of the ureters or bifid renal pelvices. Other relatives had one or more of these anomalies in a pattern suggesting autosomal dominant inheritance with reduced penetrance and variable expressivity. We suggest the term "branchio-oto-ureteral syndrome" to designate this condition.

[Bilateral bone anchored hearing aid management of children with external ear dysplasia and/or ear canal atresia].

BACKGROUND AND OBJECTIVE: The literature gives hardly any information about the benefits for children of using a bilateral bone-anchored hearing aid (BAHA) as opposed to a bilateral conventional bone conducting hearing aid. PATIENTS AND METHODS: Within a period of 12 years, three children were selected for treatment with bilateral BAHA. At the time of surgery, the children were aged between 8 and 10 years. Two of the children suffered from Franceschetti syndrome and one child from Goldenhar's syndrome. The clinical course of these three patients is presented. RESULTS: In all cases, treatment with BAHA was beneficial according to subjective and objective criteria despite localized inflammatory complications in two of the three cases. CONCLUSIONS: The bilateral use of BAHA should be considered more frequently as an alternative to conventional bone conducting hearing aids even for children.

[Surgical therapy of malignant melanoma of the external ear].

METHOD: The data from our patients of the last 10 years were evaluated in relation to survival and recurrence. RESULTS: Very different surgical therapy-in some cases due to refusal of the therapy suggested-was performed in eight patients (including wedge shaped excision as well as ablation of the auricle). The mean survival ranged from 40 months up to the present. One patient died due to a local recurrence and regional and systemic metastases. One patient experienced local recurrence but is still well 16 months after he underwent surgical revision. Two patients died independently of the tumor. DISCUSSION: Comparison of our results with those of other studies confirms that the extent of the applied resection has of minor effect on recurrence and survival for this disease. Tumor thickness is the most important independent prognostic factor.

[Squamous epithelial carcinomas of the external ear].

BACKGROUND AND OBJECTIVE: Squamous cell carcinoma of the pinna seems to be associated with a worse prognosis as compared to other locations. PATIENTS/METHODS: We studied 88 patients treated between 1975 and 1990 for a squamous cell carcinoma of the pinna. RESULTS: Lymph node metastases were present in eight cases (9%) prior to treatment. Treatment was intended to be curative in 83 patients (94%). Tumor therapy was operative in all cases. Radiotherapy was instituted postoperatively in three patients; five patients (5.7%) died due to the tumor. Of 83 curatively treated patients, only 2 died of tumor progression. The survival rate was 98% after 2 years and 95% after 5 years. The recurrence rate was 7% after 1 year, 13% after 2 years, and 18% after 5 years. The outcome with regard to local tumor control and survival was significantly poorer when neck metastases were present. CONCLUSIONS: We recommend tumor excision with wide margins (5-10 mm) as first-line treatment. Neck dissection with parotidectomy is indicated when suspicious lymph nodes are detected by ultrasound sonography, the tumor diameter is > 4 cm, cartilaginous invasion is present, and vertical tumor thickness is > 5 mm.

[External ear injuries--classification and therapeutic concept].

The treatment of traumatic defects of the auricle concerning the exact reconstruction of details and aesthetic aspects is exacting for the surgeon. To face the expectations towards best trauma care, the different locations and extent of auricular injuries should be included in the different therapeutic strategies. The insufficient treatment results in mostly difficult secondary conditions. We present a classification for ear traumas, which considers size and location of defects. Depending on this, different techniques and methods of reconstruction are recommended. Advantages and disadvantages are pointed out and discussed with several examples and with the present literature.

Morphometry of the external ear in our adult population.

This study aimed to determine the mean values of the different morphometric measurements from right and left ears. These measurements were taken from 341 healthy young adults (150 women and 191 men) ages 18 to 25 years using an electronic digital caliper. The results showed the mean values for total ear height, lobular height and width, distances from tragus to antihelix and to helix, and ear projection and width to be, respectively, 59.7 +/- 3 mm, 17.5 +/- 1.4 mm, 18.5 +/- 2.2 mm, 16.6 +/- 1.7 mm, 25.1 +/- 2 mm, 16.6 +/- 2 mm, and 31.3 +/- 2.2 mm for the left ear, and 59.5 +/- 3.1 mm, 17.9 +/- 1.5 mm, 18.9 +/- 2 mm, 16.5 +/- 1.8 mm, 25.2 +/- 1.9 mm, 17 +/- 1.9 mm, and 31.2 +/- 2.2 mm for the right ear in the young women. However, in the young men, these values were, respectively, 63.1 +/- 3.6 mm, 18.3 +/- 1.7 mm, 19.4 +/- 2 mm, 17.2 +/- 1.8 mm, 26.3 +/- 1.9 mm, 17 +/- 2.3 mm, and 33.3 +/- 2.2 mm for the left ear, and 62.9 +/- 3.5 mm, 18.4 +/- 1.7 mm, 19.8 +/- 1.9 mm, 17.2 +/- 1.8 mm, 26.6 +/- 1.9 mm, 17.6 +/- 2.1 mm, and 33.1 +/- 2.1 mm for the right ear.

[New concepts in image assisted surgery: automated patient registration based on the jaw and external ear].

OBJECTIVE: Automatic and marker less patient registration based on natural anatomical interfaces may considerably reduce the radiation load and logistical input prior to computer-assisted surgical interventions, as it is not necessary to place and measure reference markers. The present study was to find out if, apart from the facial skin, also auricles as well as the upper and lower jaw can be used as anatomical interfaces for the intraoperative registration of the patient's position. MATERIAL AND METHOD: Prior to surgical intervention the positions of 20 patients were registered by a high-resolution 3D laser scan and correlated with the preoperative CT data set. Tumors, skeletal malformations, and foreign bodies were indications for surgical intervention. Auricles as well as the upper and lower jaw were used to register the patient's positions. The accuracy of this basically marker less method was clinically evaluated through the additionally placed conventional registration markers. RESULTS AND CONCLUSION: The marker less patient registration based on natural anatomical interfaces was successful in the upper jaw (deviation: 0.8+/-0.3 mm). The tongue and mobile floor of the mouth led to geometric incongruence and inadequate laser registration in the lower jaw. As far as the auricles were concerned, high accuracy could only be achieved as long as the auricles had not been deformed during CT imaging (deviation: 1.9+/-0.9 mm). The usual CT acquisition with a conventional head support, however, led to temporary auricular deformations in more than half of the patients, which made an exact laser scan registration impossible.

Otoplasty: something old, something new. Reconstruction of the external ear using fresh cadaver homograft ear cartilage and a sternomastoid myocutaneous flap.

By combining the very old concept of using fresh cadaver homograft ear cartilage with the more modern idea of a musculo-cutaneous flap, a new ear has been constructed for a patient who was considered unsuitable for standard reconstructive procedures. The early cosmetic result appears satisfactory and the patient's hearing has been significantly improved.
