Rhino-orbital and rhino-orbito-cerebral mucormycosis

BACKGROUND: Rhino-orbito-cerebral mucormycosis (ROCM) is a devastating infection of immunocompromised hosts. We present our experience with 19 ROCM cases and attempt to define preferred diagnostic and treatment protocols. METHODS: All had tissue biopsies obtained studied by direct smear, histologic studies, and cultures. Imaging was obtained in 14 cases. RESULTS: Sixteen patients presented between August and November. Six had mixed fungal infections. Seven patients had end-stage underlying disease or infection and did not undergo surgery and 4 had an indolent form of disease. Patients were treated by surgery and by amphotericin B. The overall survival was 47%. CONCLUSIONS: ROCM may have seasonal incidence peaking in the fall and early winter. The therapeutic approach should be unchanged in cases of mixed fungal infections. Amphotericin B with aggressive debridement remains the mainstay of treatment. Early recognition and treatment are essential. A presentation and survival-dependent classification of ROCM are offered.

Patterns of metastases to the upper jugular lymph nodes (the “submuscular recess”)†

Cervical lymphadenectomy to remove metastatic disease in level II encompasses lymph nodes associated with the upper third of the internal jugular vein and the adjacent spinal accessory nerve (SAN). Conservative neck dissection (ND) preserves these structures but requires manipulation of the SAN to remove tissue located in the posterosuperior aspect of level II. Limiting the dissection to the nodal group anterior to the SAN may reduce operating time and limit injury to it without compromising the removal of lymph nodes at risk for involvement with cancer.

Quality of life of nasopharyngeal carcinoma patients

Quality of life (QOL) issues in patients with head and neck carcinoma are of importance beyond the incidence of these tumors because of the impact of the disease and its treatment on external appearance and function of the upper aerodigestive tract. Nasopharyngeal carcinoma (NPC) patients comprise a unique subgroup in whom, to our knowledge, QOL has not been studied directly.

Exclusive endoscopic ear surgery for acquired cholesteatoma: preliminary results.

Objective: To present preliminary results in transmeatal exclusive endoscopic ear surgery. Study Design: Retrospective. Intervention: Rigid endoscopes were used for all procedures. A wide posterior tympanomeatal flap was elevated transmeatally, and the scutum was removed with a bone curette or was drilled until visualization of cholesteatoma extension and the mastoid antrum. The malleus and incus were removed when they were involved in the cholesteatoma or restricted access to it. When present, the stapes was left intact. Endoscopic accessibility was defined by no extension of the cholesteatoma beyond the level of the lateral semicircular canal. Scutumplasty was by with tragal cartilage, and tympanic membrane defects were reconstructed with the palisade technique and perichondrium. Results: Thirty patients, aged 9 to 75 years, underwent the exclusive endoscopic transmeatal cholesteatoma eradication between July 2008 and May 2010. There were no incidents of iatrogenic injuries to the facial nerve or ossicles. Closure of the tympanic membrane and good hygienic status (water tolerance and absence of inflammation) were achieved in all operated ears. Two patients had significant postoperative worsening of their sensorineural hearing loss: the cholesteatoma of one of them involved all 3 ossicles and oval window and the other patient experienced postoperative labyrinthitis. There was no residual disease in 18 patients who were followed for more than 1 year, and the non-echo-planar base diffusion-weighted sequence magnetic resonance imaging was negative in 3 patients. Conclusion: Our preliminary results indicate that the minimally invasive endoscopic ear surgery allowed complete eradication of cholesteatoma from the middle ear and its extensions, with minimal morbidity and good functional results.

Pain in the Neck after Neck Dissection

BACKGROUND: Reports of disability after neck dissection have been directed toward shoulder dysfunction and pain. We could find no report addressing the issue of pain localized to the actual operative site. We have conducted a combined prospective and retrospective study of pain in patients undergoing neck dissection. METHODS: Eighty-eight disease-free patients were evaluated in 3 groups for neck pain. One group was followed up prospectively for 1 to 8 months after surgery, and 2 retrospective groups were followed up for more than 2 years or for 6 months to 2 years. Pain was assessed by a body map and visual analog scale. RESULTS: None of 31 patients followed up for more than 2 years reported neck pain. Four of 27 patients followed up for 6 to 24 months had pain, with a mean visual analog scale score of 3.7. Seventy percent of the prospective group of 30 patients had pain during the first postoperative week, and only 1 patient had pain persisting for more than 2 months. Shoulder pain and disability after radical neck dissection were encountered in all groups, comparable with the incidence reported in the literature. No postoperative neuromas were found. CONCLUSIONS: Chronic pain localized to the operative site is an uncommon occurrence even after radical neck dissection. Chronic pain in the shoulder region may follow radical neck dissection, whereas modified neck dissection is usually a painless procedure.

25-year experience of using a linear stapler in laryngectomy†

Stapler application for pharyngeal closure after total laryngectomy allows for rapid watertight closure without field contamination and for potentially reduced fistula rate.

Auricular reconstruction with a postauricular myocutaneous island flap: flip-flop flap.

&NA; Surgical defects of the concha‐helix part of the ear larger than 2 cm may pose a reconstructive challenge. Split‐ or full‐thickness skin grafts or local flaps may be used, and a number of these have been described. Yet cosmetic results are often unsatisfactory. Our experience with a postauricular myocutaneous island flap is described. Eleven patients (12 ears), aged 48 to 89 years, underwent the procedure under local anesthesia following excision of conchal bowl malignant tumors that included the cartilage underlying the skin. The surgical technique is described in detail. Few complications were encountered, and cosmetic results were excellent. In four ears, resection margins extended into the ear canal, and that portion was allowed to heal satisfactorily by secondary intention. We recommend the use of this flap for practical, safe, and early good cosmetic results.

Intracochlear schwannoma and cochlear implantation.

A case of intracochlear schwannoma in a 58-year-old candidate for cochlear implantation is described. The tumor was located in the basal turn of the cochlea and was discovered only during surgery. Computed tomography and magnetic resonance imaging obtained prior to surgery failed to detect the tumor. Intralabyrinthine schwannomas are rare tumors that grow either in the vestibule, as intravestibular schwannomas, or in the cochlea, as intracochlear schwannomas. Complete removal of this tumor was achieved through a posterior tympanotomy approach. Cochlear implantation, which resulted in good hearing, was successfully performed 3 years later.

Migration of Fishbone Following Penetration of the Cervical Esophagus Presenting as a Thyroid Mass

Fishbones are among the commonest foreign bodies lodged in the cervical esophagus. A small percentage of them will penetrate the esophageal wall and will be found either intra- or extraluminally. Migration of esophageal foreign bodies to the thyroid gland, and presentation as a mass, is extremely rare. We present such a case and review the relevant literature.

Distant metastases in terminal head and neck cancer patients

With improved control of cancer above the clavicles, distant metastases (DM) are frequently more seen and are becoming a more common cause of morbidity and mortality. The present study defined the incidence of distant metastases in a cohort of terminal head and neck cancer patients (HNCP) and compared it to current reported data. The incidence of distant metastases in relation to the primary tumour was evaluated and their impact on survival was assessed. A retrospective survey of patient charts was made, based on the hospice database and original referring hospital charts. Data of 59 patients admitted to the hospice were evaluated. The incidence and location of locoregional and distant disease were studied and effects on survival analyzed. The overall survival from diagnosis to demise was 42.7 months. Thyroid cancer was seen in 20.3 per cent of cases and squamous cell cancer was seen in 59.3 per cent. Distant metastases were found in 83 per cent and 48.6 per cent of patients respectively. Laryngeal cancer patients had a 54.5 per cent incidence of distant metastases. Locoregional disease was seen in 47 per cent of cases and 35.7 per cent of them had distant metastases while a 64.3 per cent incidence of distant metastases was found in cases without locoregional disease. Mean survival was 47.3 months with distant metastases vs 36.5 months without metastases. The difference was not statistically significant. The incidence of distant metastases in squamous cell cancer in terminal HNCP was 48.6 per cent. This is the highest reported incidence of metastases in a clinical series. Patients without locoregional disease had almost a two-fold incidence of metastases. Survival was not affected by metastases in this series.
