Atrophic rhinitis is a chronic, debilitating and recalcitrant disease of the nasal cavities that is prevalent in several parts of the world. It has unique epidemiological features and clinical characteristics. Clinicians and researchers for decades have tried to postulate theories for the aetiology of the primary form of the disease. Management of the disease has seen several medical therapeutic regimens including alternative forms of medicine. Surgical options for the condition are also not completely satisfactory with a number of failures and recurrences. The authors provide here a comprehensive review of the existing literature as regards the aetiology and management of this refractory condition.

New-onset epilepsy has several social and financial repercussions. Development of seizures after middle-fossa surgery is uncommon. We present two subjects who developed epilepsy following middle-fossa surgery, requiring treatment with anticonvulsants, and discuss the implications.

Objective: To determine whether Henle’s spine could be used as a reliable and multipurpose landmark for the other important structures of the skull base.

Materials and methods: Ninety-two specimens from 46 cadaveric adult dry skulls were studied. Two imaginary lines and a triangle were defined: a spinopterygoidal line extending from Henle’s spine to the root of the medial pterygoid plate, a bispinal line extending from one Henle’s spine to the contralateral one, and a parapetrosal triangle lying between the spinopterygoidal line, the bispinal line and the sagittal midline. The parapetrosal triangle encompasses nearly all the main structures of the skull base, including the petrosal internal carotid artery.

Results: Along the spinopterygoidal line the distance from Henle’s spine to the spine of the sphenoid was found to be about 3 cm, to the foramen spinosum 3.5 cm, to the posterior and anterior margins of the foramen ovale 4 and 4.5 cm, to the root of the lateral pterygoid plate 5 cm, to the root of the medial pterygoid plate 5.5 cm, and to the vomer 6.5–7 cm. Along the bispinal line, the distance from Henle’s spine to the stylomastoid foramen was found to be about 1.5 cm, to the lateral and medial margins of the jugular foramen 2.5 and 3.5 cm, to the external orifice of the hypoglossal canal 4 cm, and to the foramen magnum 5 cm.

Conclusion: Henle’s spine with its superficial and central position can be used to localize important anatomical structures during skull-base surgery.

Objective: To further understand the roles of bacteria and antibiotics in the development of otitis media with effusion (OME).

Methods: Samples of middle-ear effusion (MEE) were collected during the placement of ventilation tubes to treat chronic OME. Children with acute otitis media within the past three months were excluded from this study. We used polymerase chain reaction (PCR) to detect pathogens and to test the susceptibility of Streptococcus pneumoniae to penicillin.

Results: Among MEE samples from 52 children, PCR detected bacterial DNA in 32 per cent (24/75) of them. S. pneumoniae was detected more frequently in middle ears that required ventilation tube insertion at least twice compared with those requiring ventilation tube insertion only once (5/15 versus 4/60; p = 0.013). Higher levels of S. pneumoniae were detected in MEE from children with, than without, a long history of antibiotic administration (7/10 versus 2/14; p = 0.0187). The pbp genes of all isolated S. pneumoniae contained mutations.

Conclusions: Long exposure to antibiotics might significantly influence the bacterial genome in MEE.

The purpose of this retrospective study is to determine the pattern of cerebrospinal fluid (CSF) rhinorrhoea presenting to our tertiary referral centre in Kuala Lumpur and to assess the clinical outcomes of endonasal endoscopic surgery for repair of anterior skull base fistulas. Sixteen patients were treated between 1998 and 2004. The aetiology of the condition was spontaneous in seven and acquired in nine patients. In the acquired category, three patients had accidental trauma and this was iatrogenic in six patients (five post pituitary surgery), with one post endoscopic sinus surgery (ESS). Imaging included computed tomography (CT) scan and magnetic resonance imaging (MRI). Endoscopic repair is less suited for defects in the frontal sinuses with prominent lateral extension and defects greater than 1.5 cm in diameter involving the skull base. Fascia lata, middle turbinate mucosa, nasal perichondrium and ear fat (’bath plug’) were the preferred repair materials in the anterior skull base, whereas fascia lata, cartilage and abdominal fat obliteration was preferentially used in the sphenoid leak repair. Intrathecal sodium flourescein helped to confirm the site of CSF fistula in 81.3 per cent of the patients. Ninety per cent of the patients who underwent ’bath plug’ repair were successful. The overall success rate for a primary endoscopic procedure was 87.5 per cent, although in two cases a second endoscopic procedure was required for closure. In the majority of cases endoscopic repair was successful, and this avoids many of the complications associated with craniotomy, particularly in a young population. Therefore it is our preferred option, but an alternative procedure should be utilized should this prove necessary.

Aim: To evaluate the criteria for diagnosing allergic fungal sinusitis and to maintain permanent drainage and ventilation, while preserving the integrity of mucosa. Methods: This is a prospective study of 251 patients with chronic rhinosinusitis with or without polyposis, of whom 199 were treated surgically. Mucus sample collection, nasal secretion culture, surgical specimen handling and histological evaluation of surgical specimens are described. The management included wide local endoscopic sinus debridement, adequate sinus aeration, post-operative use of steroids and antifungal therapy. Results: Fungal cultures of nasal secretions were positive in 201 (80.01 per cent) of 251 patients. Of the 199 surgical cases, fungal elements were found in 156 histological specimens (62.1 per cent). Allergic mucin was found in 182 patients (91.45 per cent). Nasal obstruction and proptosis were the commonest presentations. All pre-operative versus post-operative changes in AFS-associated complaints reached statistical significance of p < 0.001. The ethmoid sinus was commonly involved with adjacent lamina papyracea exhibiting demineralization in 26.6 per cent of cases. Intracranial extension was seen in 15 cases. Recurrence was noted in 11 cases. Conclusion: Comprehensive treatment with endoscopic sinus surgery, steroids and antifungal therapy is needed. AFS is readily recurrent. Long-term follow up is important.

The aim of this study was to compare the effectiveness of technetium-99m methoxyisobutylisonitrile (99mTc-MIBI) single-photon emission computed tomography (SPECT) and computed tomography (CT) in evaluating cervical lymph node metastasis of head and neck cancer. Histopathologic results of 166 cervical lymph node levels in 31 neck-dissected patients were compared with pre-operative CT and 99mTc-MIBI SPECT findings about cervical lymph node metastasis, retrospectively. Sensitivity, specificity and predictability of CT and 99mTc-MIBI SPECT were 68.2, 93.1 and 89.8 per cent and 59.1, 87.5 and 83.7 per cent, respectively. When analysing CT and99mTc-MIBI SPECT together, sensitivity and specificity were 86.4 and 99.3 per cent, respectively. The combined use of 99mTc-MIBI SPECT and CT could increase the accuracy of cervical lymph node metastases detection, compared with separate use of either 99mTc-MIBI SPECT or CT.

Objective and hypothesis: Obstructive sleep apnea (OSA) is a relatively common and serious problem with many medical and social consequences. Laser and radiofrequency are two recent techniques used to treat OSA and they can be carried out under local anaesthesia, but they need multiple sessions to achieve satisfactory outcome and are associated with better short-term than long-term outcomes. In this work we compare the two modalities as regards the optimal number of treatment sessions needed to achieve a favourable outcome in the short and long term. Study design: A total of 150 patients with apnoea hypopnoea index (AHI) between 5 and 30 events per hour, no morbid obesity and retropalatal site of obstruction were included in this prospective study. Methods: Patients were randomly and equally divided into two groups, each comprising 75 patients. The first group was treated with bipolar radiofrequency volumetric tissue reduction of the palate (BRVTR) and the second group was treated with laser-assisted uvulopalatoplasty (LAUP). Each group was further subdivided into five subgroups each consisting of 15 patients. The first group received one treatment session, the second received two sessions, the third received three sessions, the fourth received four sessions and the fifth group received five treatment sessions. Evaluation of efficiency of both techniques in treating OSA was assessed objectively by polysomnography. Results: In those treated with BRVTR; at least three sessions were needed to achieve a favourable outcome in OSA in the short and long term. In those treated with LAUP, a single treatment session was enough to achieve a favourable outcome on OSA in the short term, while two sessions were needed to achieve the same long-term outcome. Discussion: In OSA, fewer treatment sessions are needed with LAUP (one session) than with BRVTR (three sessions) to achieve a favourable outcome. In LAUP more treatment sessions (two) are needed to maintain a longer-term favourable outcome than those needed to achieve short-term favourable outcome (one session), which is not the case with BRVTR (three sessions are needed to achieve both short- and long-term favourable results).

The aim of this study was to determine whether certain weather variables influence the secondary post-tonsillectomy haemorrhage rate and to examine the influence of a change in these variables on secondary haemorrhage. This was a prospective study carried out in a tertiary referral institution. All patients undergoing bilateral tonsillectomy over a one-year period were included. Local weather data, including daily temperature (max/min), relative humidity and water vapour pressure, were acquired. All patients readmitted to our department with secondary post-tonsillectomy haemorrhage were recorded. Of 346 patients undergoing tonsillectomy, 32 developed secondary haemorrhage (9.2 per cent). A significant negative correlation was found between secondary haemorrhage rate and the average monthly temperature (max/min) and water vapour pressure (Pearson’s correlation = −0.8) (p ≤ 0.002). These results suggest that performing tonsillectomy in warmer weather when the water vapour pressure is higher may reduce the secondary haemorrhage rate.

Objectives: Lesions in the anterior segment of the vocal fold are sometimes difficult to access by means of conventional suspension microlaryngoscopy under general anaesthesia because of anatomical factors such as short, stout and inflexible necks, reduced jaw protrusion, and long incisors. Various techniques have recently been proposed for the management of inaccessible glottic lesions, most of which are performed under general anaesthesia. The use of flexible videoendoscopic surgery under topical anaesthesia in two cases of anterior glottic lesions that could not be treated by means of conventional suspension laryngoscopy is described.

Study design: Case report.

Methods: A flexible videobronchoscope with an instrument channel was inserted transnasally on an out-patient basis. While the examiner carried out the endoscopy, an assistant manoeuvred the biopsy forceps through the instrument channel, and removed the lesion.

Results: Both patients underwent successful removal of an anterior glottic polyp, and the one-year follow-up evaluation revealed normal anatomy of the vocal folds and normal vocal function.

Conclusions: Flexible videoendoscopic surgery under topical anaesthesia is a safe, simple and minimally invasive procedure that can be considered as an alternative to traditional endoscopic surgery for inaccessible anterior glottic lesions.

Since the first reliable mediastinal tracheostomy described by Grillo et al. in 1966, many new techniques have been described in order to reduce the number of complications. We here report the case of a 55-year-old man who was referred for surgery with post-radiochemotherapy recurrence of a double neoplasm of the pharyngolarynx extending to the proximal trachea and the medial part of the oesophagus. Through a median sternotomy, a pharyngolaryngoesophagectomy was performed with an extended tracheal resection. The reconstruction of the upper digestive tract was performed with a gastric pull-up. The mediastinal tracheostomy was performed with a pectoralis major muscular flap through a right unilateral resection of the manubrium, the right clavicular head and the right first and second costal cartilages. Historically, the mediastinal tracheostomy was performed through a large bilateral resection of the anterior chest wall, in order to prevent the tension on the tracheocutaneous sutures. Nowadays, with the possibility of various pedicled flaps, bilateral resection no longer seems to be necessary. This unilateral resection leads to a reduction in post-operative sequelae.

Iatrogenic injury to the spinal accessory nerve (SAN) during neck dissection may result in significant and avoidable morbidity in the form of ’shoulder syndrome’. The authors describe a simple method, based on the anatomy of the sternocleidomastoid muscle (SCM), which allows consistent and rapid identification of the SAN in the upper neck during dissection, thereby facilitating its preservation.

Parapharyngeal abscess as a complication of cholesteatoma is an uncommon entity. Endopharyngeal common carotid artery rupture due to parapharyngeal abscess is also uncommon, and these cases usually end fatally. We present a 17-year-old male with parapharyngeal abscess due to cholesteatoma who developed an endopharyngeal common carotid blow out and survived after common carotid ligation without any neurological sequalae.

Anterior cervical spine fusion and stabilization is a well-recognized procedure for a number of cervical spine disorders. Unfortunately, the complex anatomy of the cervical spine means that these procedures are not without complications. Pharyngo-oesophageal perforation is a rare but potentially life-threatening complication of cervical spine surgery and may present intra-operatively, in the immediate post-operative period or many years later. We present the case of a gentleman with ankylosing spondylitis who presented with a pharyngeal perforation and fistula five years after cervical spine surgery.

Aims: to determine correlations between relative quantities of telomerase catalytic subunit m-ribonucleic acid (hTERT mRNA) and conventional clinicopathological parameters (such as site, size and grade of tumour, the presence of regional lymph node metastases, and, in particular, survival) in patients with laryngeal and hypopharyngeal squamous cell carcinomas (SCCs).

Material and methods: The relative quantity of hTERT mRNA was analysed by a commercially available LightCycler Telo TAGGG hTERT Quantification Kit in 56 cases of SCC (40 laryngeal and 16 hypopharyngeal). The association with cancer-specific survival was evaluated by univariate and multivariate analysis.

Results: Location of the tumour in the hypopharynx was the only significant negative predictive factor for survival, as determined by univariate analysis (p = 0.028). Although a tendency towards a better overall survival was observed for female patients younger than 50 years, for lower tumour grades and sizes, and for the absence of regional lymph node metastases, the prognostic significance of these factors could not be confirmed. No differences existed in hTERT mRNA expression between laryngeal and hypopharyngeal SCCs. Furthermore, no correlation was found between the relative quantities of hTERT mRNA and the tumour size, regional lymph node metastases or survival of patients with laryngeal or hypopharyngeal SCCs.

Conclusions: The results of the present study suggest that genetic abnormalities other than telomerase reactivation are responsible for progression of laryngeal and hypopharyngeal SCCs.

Laryngeal necrosis is a serious complication that usually occurs within the first year following completion of radiotherapy, although it is reported that cases can develop after a long period of latency. Factors such as dosage and irradiation technique employed, tumour invasion into the laryngeal cartilage, infection, continued smoking, trauma and general vascular condition of the patient have been considered to increase the rate and degree of development of radionecrosis. We report an unusual case of laryngeal radionecrosis in a patient with hypertension, hyperlipidaemia, diabetes and a history of cigarette smoking, which developed 25 years after radiotherapy for laryngeal carcinoma. His systemic illnesses and continued smoking were speculated to have contributed to the progress of the radionecrosis, suggesting that cessation of smoking and control of arteriosclerotic diseases should be considered to decrease its incidence.

We present the case of Munchausen’s syndrome by proxy (MSBP) in which the mother spat and placed blood in her child’s ear, and videoed the result, in order to gain the attentions of the medical profession. This is the first case report of this kind and may represent a disturbing trend in the use of digital photography and video to support factitious illnesses.

The authors describe a patient who presented with a left sublingual swelling. Ultrasonic and sialographic investigation showed no salivary tissue in the expected left submandibular region, but a large salivary gland in the left floor of the mouth deep to the mylohyoid muscle. This is likely to represent an ectopically positioned submandibular gland.
