The aim of this work was to determine the effect of extracorporeal shock wave lithotripsy (ESWL) on the hearing of both patients and staff members exposed to such treatment. It used different hearing screening instruments, and compared the sensitivity of these instruments for the detection of the earliest change in hearing induced by this procedure.

The results of this study show that ESWL has a potentially hazardous effect on hearing. This effect is subtle, could only be detected by transient evoked otoacoustic emissions (TEOAE), and is manifested in some of the subjects under study as temporary subjective hearing loss and tinnitus, reflecting a state of temporary biomechanical derangement of the outer hair cells. This effect seems to be related to the frequency of exposure to ESWL.

Graves’ disease may occasionally result in significant proptosis that is either cosmetically unacceptable or causes visual loss. This has traditionally been managed surgically by external decompression of the orbital bony skeleton. Trans-nasal endoscopic orbital decompression is emerging as a new minimally-invasive technique, that avoids the need for cutaneous or gingival incisions. Decompression of the medial orbital wall can be performed up to the anterior wall of the sphenoid sinus. This can be combined with resection of the medial and posterior portion of the orbital floor (preserving the infra-orbital nerve). This technique produces decompression which is comparable to external techniques.

We present a series of 10 endoscopic orbital decompressions with an average improvement of 4.4 mm in orbital proptosis. There was an improvement in visual acuity in all patients with visual impairment. Endoscopic orbital decompression is recommended as an alternative to traditional decompression techniques.

The delivery of nasal drugs specifically to the middle meatus is of critical importance in the medical treatment of rhinosinusitis. In this respect, topical nasal drug administration by drops has generally been perceived to be superior to nasal sprays, although there is a lack of evidence to support this notion. This study aims to compare the intranasal delivery of nasal sprays and drops to the middle meatus in vivo, using a novel quantitative method. A surgical patty was placed in the middle meatus. Radio-labelled topical nasal drops and aqueous sprays were administered in a standardized fashion in normal volunteers (10 nasal cavities). The subsequent absorption of administered radio-labelled saline on the patty was measured using a gamma counter. A randomized prospective crossover design was used for the study. The mean percentage (range) of absorbed administered saline on the swab was 8.7 (0.3–39.5) and 9.7 (0.03–20.4) for the spray and drop administration techniques respectively (p = 0.8). Thus, there is wide variation in the delivery of topical nasal drugs and the perceived superiority of nasal drop administration, in terms of delivery to the middle meatus, may be incorrect.

It is well established that laryngeal secretions, produced in the glandular tissue, contribute to the local defence system of the larynx. In this study, the distribution of glandular tissues in the subglottic and supraglottic larynx was examined in 55 infants, using an image analysing system. The average area of the mucosa or glandular acini at the level of the false vocal fold was almost three times larger than that of the subglottis. At both levels, the area occupied by the glands increased according to the age at death and became more evident according to the total development score (TDS) which was estimated by adding the age at death and the gestational period. The results indicate that the glandular structure of the level of the sub- or supraglottic larynx develops constantly and equally after birth.

In this paper we report our experience of vertical partial laryngectomy using the superficial cervical fascia; we describe the technique and present the functional and oncological results of this method of treatment.

A total of 42 patients with squamous cell carcinoma of the true vocal folds, in stage T1 (n = 28) or T2 (n = 14), were treated in our department using vertical partial laryngectomy during the decade 1987–1997. Nine patients had post-operative radiotherapy. The shortest follow-up time was three years. There were six recurrences in all, four in the larynx and two in the neck. All four of the laryngeal recurrences were treated with total laryngectomy and are doing well. Both the patients with neck metastases, who were treated with neck dissection, died. Permanent tracheotomy was necessary in one patient. There were no problems with aspiration. The recurrence rate was 14 per cent, the three-year survival index was 95.2 per cent and the three-year larynx preservation index was 90 per cent. According to our experience, vertical partial laryngectomy, using the method we describe, has a good functional and oncological result for stage T1 and T2 tumours.

A series of squamous cell carcinomas (SCC) of the hypopharynx treated with combined surgery and radiotherapy is presented to highlight the results of treatment at an early stage of disease. A retrospective mono-institutional analysis was performed on 153 previously untreated patients with SCC of the hypopharynx, seen between 1980 and 1995 at our institution. Univariate and multivariate analyses were performed using the Cox proportional hazard model. The overall five-year specific, and non-specific, disease survival rates were 68 per cent (95 per cent confidence interval, CI: 60–77) and 47 per cent (95 per cent CI: 39–56), respectively. Compared with other series, this study is characterized by treatment at an earlier stage, better prognosis, and a higher number of multiple malignancies. Twenty-two per cent of hypopharyngeal SCCs were diagnosed during the staging procedures for a different head and neck SCC and 14 per cent during the follow-up for a previous tumour. Multivariate survival analysis of clinical and pathological factors confirmed the clinical class of tumour (T) and node (N) and the nodal capsular rupture as prognosticators of disease.

There is considerable controversy surrounding the optimum treatment of advanced hypopharyngeal cancers. Curative radiotherapy with surgical salvage in reserve is an accepted protocol as is also a combined treatment of surgery and radiotherapy. The present study is a retrospective analysis of the survival results of 195 cases treated in a single centre. The combined surgery and radiotherapy group comprised a greater number of pyriform fossa and post-cricoid tumours whereas, the curative radiotherapy group had a higher proportion of posterior pharyngeal wall tumours. Actuarial two-year disease-free survival rates were significantly better with combined treatment when results of stage III and IV lesions (164 patients) of all sites are taken together, as compared to those obtained with curative radiotherapy without salvage (p = 0.000) or radiotherapy with surgical salvage for residual/recurrent tumours (p = 0.0021).

Post-operative pain and delayed oral intake are common reasons for failure of discharge in day-case tonsillectomy. A double blind prospective randomized study was devised to investigate the effectiveness of topical bupivacaine in reducing post-operative pain in paediatric day-case tonsillectomy. Ninety-nine patients aged between three and 16 years were recruited into the study. One group received bupivacaine soaked swabs tightly packed in their tonsillar fossae while the control group received saline-soaked swabs. The bupivacaine group was found to drink (p < 0.001) and eat (p = 0.006) earlier than the control group. The pain scores at one (p < 0.001), three (p < 0.001) and six (p < 0.001) hours post-operatively were also found to be lower in the bupivacaine group than the control group. We conclude that topical bupivacaine has a role in facilitating recovery in day-case tonsillectomy in children.

The application of a reliable adequate pressure dressing to one side of the neck has always proved difficult, because of the risk of occluding the airway and the vasculature. We describe a method of maintaining well-localized pressure to one side of the neck without undue pressure on the vasculature and the airway by using a stiff cervical collar. This method was used successfully in the conservative management of neck haematoma in two patients.

A 53-year-old female presented with a painful swelling within her external auditory meatus. Biopsies revealed this to be a B-cell lymphoma and she underwent surgical treatment followed by chemotherapy. This is the first reported case of non-Hodgkin’s lymphoma of the external auditory meatus in an human immunodeficiency virus (HIV)-negative patient.

Treatment of auricular arteriovenous fistula (AVF) is a challenge with surgery being the preferred option until now. We present three cases of auricular AVFs who underwent pre-operative embolization and its outcome on surgery. Three patients were diagnosed to have auricular AVF by angiography. All three patients underwent pre-operative embolization with n-butyl 2-cyanoacrylate after which they underwent surgical resection of the AVF. Pre-operative embolization resulted in significant devascularization of the AVF thus leading to near bloodless and clean surgery. Pre-operative embolization of auricular AVFs is a good treatment option, leading to significantly reduced blood loss during surgical excision.

Bilateral simultaneous facial nerve palsy is an extremely rare clinical entity with Bell’s palsy responsible for a mere 20 per cent of cases. It is, therefore, important that clinicians are aware of the differential diagnosis when evaluating a case.

A case of a female child of six years of age with a plexiform neurofibroma of the larynx caused by von Recklinghausen’s disease is presented. Laryngeal involvement in neurofibromatosis type 1 (NF1) is rare and only 19 paediatric cases have been reported. The tumour was biopsied and lateral pharyngotomy with supraglottic hemilaryngectomy was performed in order to relieve obstructive symptoms. Problems related to this unusual tumour localization are discussed and a review of the literature is presented.

Most of the malignancies arising from the upper respiratory system are squamous cell carcinomas (SCC). Basaloid squamous cell carcinoma (BSCC) is a rarely seen high grade variant of SCC that carries a poor prognosis. In this article, we present a case of BSCC of the larynx. In addition, we provide a review of the relevant literature along with a discussion of the differential diagnosis.

Amyloidoses are a group of disorders in which deposition of abnormal amounts of protein complexes (amyloid) occurs in a variety of tissues. The upper aerodigestive tract may be affected, particularly the larynx, but hypopharyngeal involvement is rarely reported. We present a unique case of amyloidosis of the post-cricoid region causing dysphagia.

This case report highlights the need for otolaryngologists to consider the possibility of submucosal amyloid deposition, in the absence of mucosal lesions, in patients who present with dysphagia secondary to an obstructive lesion of the post cricoid region.

The advantages of endoscopic transnasal pituitary surgery include a panoramic view of the area and easy reoperation. Based on this, we performed a planned staged operation in two cases of large pituitary adenomas, extending to the suprasellar lesion, using the endoscopic transnasal trans-sphenoidal approach via both nostrils. In the initial operation, a tumour mass was from the intrasellar region, however, that part of it in contact with the tumour capsule was left intact for prevention of peri-operative injury. The residual mass descended into the sellar floor at the second operation, and was easily resected with no complications. A staged operation by the endoscopic transnasal approach, although it requires two operations, is thought to be a safe and efficient procedure for the removal of large pituitary tumours.

Extracorporeal shock wave lithotripsy, a relatively new non-invasive method of treating salivary gland calculi, is rarely used in UK hospitals. We present a case of parotid duct calculus treated successfully by lithotripsy in a United Kingdom (UK) district General Hospital.

Most schwannomas of the hypoglossal nerve originate from the intracranial portion, but they may extend extracranially. Solitary and extracranial schwannomas are extremely rare. We report a case of submandibular hypoglossal schwannoma along with its clinical course and management.

Mandibular osteochondromas, although rare, predominantly involve the condyloid and coronoid processes. An extremely rare case arising from the inner aspect of the gonion is reported here. Only one such case has been reported in the literature so far. Despite being very slow growing and having a benign course, histopathological examination showed reactive changes that may be confused with sarcomatous transformation. We advocate surgical excision using a combined external and internal approach followed by regular post-operative review. The relevant literature has been reviewed but various surgical approaches as advocated in the past have not been found suitable.
