    The Incidences of Chondritis and Perichondritis Associated With the Surgical Manipulation of Auricular Cartilage

    DERMATOLOGIC SURGERY, Issue 1 2004
    Andrew L. Kaplan MD
    Background. The cartilage and soft tissues of the ear are frequently employed as donor sites for tissue used in the repair of defects of the nose and external ear after Mohs surgery. Enthusiasm for using these auricular donor sites is occasionally tempered by surgeons' concerns for the development of Pseudomonal suppurative chondritis, a complication that has been described to follow cartilage manipulation. Objective. To quantify the incidence of postoperative perichondritis and chondritis after Mohs reconstructions involving auricular cartilage manipulations. Methods. We retrospectively reviewed 341 Mohs reconstructions that involved cartilage and soft-tissue donor sites located on the ear. Procedures included full-thickness skin grafts (295) harvested from the conchal bowl and flap repairs (46) incorporating cartilage batten grafts from conchal or anthelix donor sites. When the perichondrium was compromised, patients were routinely prescribed perioperative prophylactic antibiotics with Pseudomonal coverage. Postoperative examinations were performed at 1 week and 4 to 12 weeks. Patients not seen in clinic were interviewed by telephone regarding complications. Results. Complete follow-up information was obtained in 337 of 341 (98.8%) cases. Inflammatory perichondritis was observed in 19 (5.6%) patients. There were no cases of suppurative chondritis. Conclusion. The incidence of inflammatory perichondritis is low after Mohs reconstructions involving auricular cartilage manipulation. When prophylactic antibiotics and appropriate operative technique are used, the historic concern for suppurative chondritis associated with these procedures is unwarranted. [source]

    Toothache referred from auriculotemporal neuralgia: case report

    INTERNATIONAL ENDODONTIC JOURNAL, Issue 9 2009
    R. A. Murayama
    Abstract Aim, To present a 52-year-old male patient who complained of intense pain of short duration in the region of the left external ear and in the ipsilateral maxillary second molar that was relieved by blockade of the auriculotemporal nerve in the infratemporal fossa. Summary, Extra- and intraoral physical examination revealed a trigger point that reproduced the symptoms upon finger pressure in the ipsilateral auriculotemporal nerve and in the outer auricular pavilion. The patient's medical history was unremarkable. The maxillary left second molar tooth was not responsive to pulp sensitivity testing and there was no pain upon percussion or palpation of the buccal sulcus. Periapical radiographs revealed a satisfactory root filling in the maxillary left second molar. On the basis of the clinical signs and symptoms, the auriculotemporal was blocked with 0.5 mL 2% lidocaine and 0.5 mL of a suspension containing dexamethasone acetate (8 mg mL,1) and dexamethasone disodium sulfate (2 mg mL,1), with full remission of pain 6 months later. The diagnosis was auriculotemporal neuralgia. Key learning point ,,Auriculotemporal neuralgia should be considered as a possible cause of nonodontogenic toothache and thus included in the differential diagnoses. ,,The blockade of the auriculotemporal nerve in the infratemporal fossa is diagnostic and therapeutic. It can be achieved with a solution of lidocaine and dexamethasone. [source]

    Hereditary benign telangiectasia: first case in Iran

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 7 2006

    A 14-year-old boy was referred to the Dermatology Clinic of the Medical University of Mashhad, Iran, with numerous cutaneous telangiectasias on the face, ears, lips, and back of the hands, with lesions in the temporal region being the first to appear (Figs 1,3). His mother stated that the lesions had been present for 10 years with an increase in the past 6 months. He had no history of bleeding from the nose, mouth, gastrointestinal tract, and other mucosal surfaces, and there was no sign of organ involvement. On inspection, no lesions were detected on the nasal mucosa, external ear, over the tympanic membrane, or mouth. Figure 1. Numerous telangiectasias affecting the cheeks, nose, and perioral areas Figure 2. Lateral view of Fig. 1 Figure 3. Telangiectasias affecting the dorsal aspect of the hands The patient is one member of a family of six. His mother is healthy, but similar lesions were seen in his father, sister and one of his brothers with similar distributions. Lesions were also seen in his aunt and paternal grandmother, showing disease distribution in six members of this family from three generations. The oldest brother is 20 years of age and mentioned the onset of disease from the age of 10 years. The sister is 18 years of age and lesions started to appear 7 years ago; she claims that the lesions regress during her menstrual period. The youngest brother is 4 years of age and shows no sign of cutaneous lesions as yet. The parents are not consanguineous. Generalized telangiectasia with a predominant distribution on light-exposed skin, an autosomal dominant inheritance, and no sign of systemic or mucosal involvement and bleeding disorders indicates a diagnosis of hereditary benign telangiectasia. Our patient did not consent to biopsy. [source]

    The Preauricular Sinus: A Review of its Clinical Presentation, Treatment, and Associations

    PEDIATRIC DERMATOLOGY, Issue 3 2004

    Usually asymptomatic, they manifest as small dells adjacent to the external ear near the anterior margin of the ascending limb of the helix, most frequently on the right side. Preauricular sinuses can be either inherited or sporadic. When inherited, they show an incomplete autosomal dominant pattern with reduced penetrance and variable expression. They may be bilateral, increasing the likelihood of being inherited, in 25,50% of cases. Preauricular sinuses are features of other conditions or syndromes in 3,10% of cases, primarily in association with deafness and branchio-oto-renal (BOR) syndrome. When other congenital anomalies coexist with these sinuses, auditory testing and renal ultrasound should be considered. Sinuses may become infected, most commonly with gram-positive bacteria, in which case their exudates should be cultured and appropriate antibiotics administered. Recurrent infection is a clear indication for complete excision and provides the only definitive cure. Recurrence rates after surgery range from 9% to 42%. Meticulous excision by an experienced head and neck surgeon minimizes the risk of recurrence. [source]

    A population-based study of skin cancer incidence and prevalence in renal transplant recipients

    BRITISH JOURNAL OF DERMATOLOGY, Issue 3 2006
    F.J. Moloney
    Summary Background, Cancers occurring following solid organ transplantation are a rapidly growing public health concern. Defining the extent of the problem has been limited by surveillance systems with incomplete registration of cases and the paucity of reliable national incidence data. Objectives, To determine the incidence of all cancers following renal transplantation and to make a detailed examination of trends and patterns associated with postrenal transplant skin cancers. Methods, Integration of data from the national renal transplant database and the national cancer registry in Ireland enabled accurate determination of the number of renal transplant recipients (RTRs) with skin cancers and other malignancies in the time period 1 January 1994 to 31 December 2001. Results, We demonstrated a biphasic increase in skin cancer incidence following renal transplantation, determined by the age at transplantation. There was a steady increase in risk for older RTRs (age 50+ years) from year 2 post-transplant, whereas the increased risk in younger RTRs (age <,50 years) occurred later but much more significantly, reaching 200 times the risk for an age-matched nontransplanted population by year 6 post-transplant. The number of nonmelanoma skin cancers (NMSCs) registered in RTRs accounted for 1% of all NMSCs registered nationally over the study period. The standardized incidence rates for invasive NMSC (33-fold increase) and in situ carcinoma of the skin (65-fold increase) were significantly increased (P < 0·05). The risk for invasive squamous cell carcinoma (SCC) was increased 82-fold compared with the nontransplanted population. Male RTRs were at particular risk of invasive SCC at sun-exposed sites such as the scalp and the external ear. Risk of malignant melanoma and Kaposi sarcoma were also increased relative to the nontransplanted population. Conclusions, This comprehensive national study illustrates how rates of skin cancer in Irish RTRs have influenced the national incidence of skin cancer. The high incidence of SCC, basal cell carcinoma and Bowen's disease in the early post-transplant period for older patients and the cumulative risk in younger patients with increased duration of transplantation highlight the importance of implementing early and continued cancer surveillance regimens post-transplant.
