A laryngocoele is an abnormal dilatation of Morgagni's ventricle in direct communication with the laryngeal lumen. Surgical excision through a cervical approach is traditionally considered the treatment of choice for large (external and mixed) laryngocoeles. This paper describes the first reported case of a large mixed laryngocoele treated with transoral robotic surgery without cervical incisions.

A 69-year-old female underwent transoral robotic surgery for the excision of a large mixed left laryngocoele. The surgery was performed using the da Vinci S surgical robotic system (Intuitive Surgical, Sunnyvale, California, USA).

No complications were observed and the patient was discharged 2 days post-operation.

Transoral robotic surgery enabled accurate dissection with complete removal of the large mixed laryngocoele via a minimally invasive approach. The advantages of transoral robotic surgery over other techniques for laryngocoele excision are discussed.

We report three cases of lateral outfracture of the inferior turbinate, which demonstrate a range of changes in the size, position and shape of the inferior turbinate.

During a study of the validity of computer modelling of nasal airflow, computed tomography scans of the noses of patients who had undergone lateral outfracture of the inferior turbinate were collected. The pre-operative scan was compared with the post-operative scan six weeks later.

In one patient, there was only a small lateral displacement of the inferior turbinate. In the other two cases, appreciable reduction in the volume of one inferior turbinate was noted, in addition to minor changes in the shape.

Lateral outfracture of the inferior turbinate produces varied and inconsistent changes in morphology which may affect the shape, size and position of the turbinate.

Small cell carcinoma of the head and neck is rare and has unique histopathological characteristics that make it difficult to diagnose and treat. In this report, the Japanese Lung Cancer Treatment Guidelines were adapted to treat three patients with small cell carcinoma of the head and neck, and outcomes evaluated.

There was one case each of stage I small cell carcinoma of the nasal cavity, stage IV-B small cell carcinoma of the ethmoid sinus, and stage IV-A small cell carcinoma of the submandibular gland. All patients underwent chemoradiotherapy and achieved a partial response.

Only case one underwent surgery after chemoradiotherapy; 31 months after treatment, this patient had suffered no recurrence. Case two died three months after treatment due to bone marrow metastasis. Case three had experienced no progression after 12 months of follow up.

In this small patient series, short-term results were equivalent to or better than usual treatment outcomes for small cell carcinoma of the lung.

To discuss the histopathogenesis and treatment choices for synchronous tumours of the larynx.

We present two cases of synchronous laryngeal leiomyosarcoma and squamous cell carcinoma. The first case was an early-stage tumour and the second an advanced-stage tumour of the larynx. Selection of adequate treatment for synchronous tumours is difficult because of different spreading rates and metastatic patterns. Treatment choices for both the primary tumour site and the neck should be related to the stage of the squamous component of the tumour.

In such cases, the tumour location, tumour stage and lymphatic metastases must be carefully evaluated in order to make the optimum treatment choice. Treatment evaluation of the neck should be related to the stage of the squamous component of these synchronous tumours. Partial laryngectomy techniques may be preferred if the extent of the disease permits.

Cervical spine metastases account for 10 per cent of all spinal metastases. We report three cases of cervical spine metastases whose unusual primary presentation was with ENT-related symptoms.

The three patients reported herein did not have a confirmed diagnosis of malignancy at presentation. The first patient presented with stridor, the second presented with dysphagia and the third presented with dysphonia. All patients complained of significant neck pain that preceded and was concomitant to the other symptoms. Clinical suspicion of cervical spine involvement led to radiological investigation with computed tomography, which showed metastatic lesions in the craniovertebral junction and cervical spine region. Histological confirmation of malignancy was obtained for two of the three patients. The condition proved uniformly fatal in the weeks following diagnosis. A review of the literature on this condition was conducted using PubMed and Medline databases.

Cervical spine pathology may present initially to the ENT surgeon. A high degree of suspicion of cervical spine involvement should be maintained in elderly patients with persistent or progressive neck pain, with or without other ENT symptoms. Adequate radiological imaging will usually confirm the diagnosis.

To describe the management of a 15-year-old girl with repeated life-threatening complications of her tracheostomy secondary to muscle dystonia and thoracolumbocervical lordosis.

This paper reports a retrospective case review.

Regular microlaryngoscopy and bronchoscopy, treatment with systemic steroids and a soft tracheostomy tube, in addition to better control of the dystonia, resulted in control of the patient's airway. This minimised tracheal inflammation and granulation tissue formation.

The need for a tracheostomy in patients with thoracolumbocervical lordosis and severe dystonia should be considered only after all other options of airway management have been explored. Every attempt should be made to minimise tracheal trauma caused by excessive movement of a tracheostomy tube.

To report two cases of laryngeal plasmablastic lymphoma, a rare and relatively recently described form of non-Hodgkin's lymphoma. It has not previously been described in the larynx, nor associated with upper airway obstruction.

We describe the clinicopathological features of two such cases in human immunodeficiency virus positive patients, and we discuss their unusual presentations and diagnostic features.

When evaluating a laryngeal tumour, plasmablastic lymphoma and other non-Hodgkin's lymphomata should be considered as differential diagnoses, particularly in the setting of a high prevalence of human immunodeficiency virus infection. Biopsy with detailed histopathological and immunohistochemical evaluation is recommended to ensure correct diagnosis and optimal management.

It is rare for isolated sphenoid sinusitis to cause orbital cellulitis. We present a rare case of posterior orbital cellulitis, so caused, together with a review of the relevant literature.

A 29-year-old woman presented with a 6-week history of progressive, unilateral, retro-orbital and periorbital right eye pain. On examination, the only finding was reduced visual acuity in the right eye. A computed tomography scan demonstrated right frontal and sphenoid sinus opacification. Sphenoidotomy and frontal sinus trephination were subsequently performed, following failure to respond to intravenous antibiotics. After surgery, the patient's vision returned to normal.

Isolated sphenoid sinusitis is rare but can cause significant visual disturbance and permanent loss of vision. Vague symptoms unsupported by clinical signs at presentation are a feature of posterior orbital cellulitis. The presented case highlights the problem, and the need for a high index of clinical suspicion even in the absence of firm clinical signs, in order to prevent permanent visual loss.
