Sixty-three cases of squamous papillomas of the larynx occurring in adults are presented. Twelve cases started as juvenile papillomas and continued into adult life. Twice as many males as females were in the series. The papillomas were always present on the true vocal cords at presentation, although other parts of the larynx were involved to a variable extent. The symptom of hoarseness gave a good indication as to the state of the larynx during treatment. Malignancy did not develop in patients with papillomas which fulfilled the histological criteria. Papillomas are clusters of thin, cylindrical projections of squamous epithelial covered mucosa with second and even third order branching. Biopsies in 5 cases show papillomatosis of respiratory epithelium, a process which is here described in the larynx for the first time. The prognosis as regards recurrence for 20 patients with solitary lesions was good, for 38 patients with multiple lesions reasonable, but for 5 patients with extensive florid lesions was exceptionally poor.

Topical 5FU treatment improves survival of Woodworker's adenocarcinoma of the ethmoid sinuses. This finding may be useful in the treatment of other locally aggressive sinonasal malignancies.

Several risk factors have been postulated to play a part in the progression of acute into chronic otitis externa, including changes towards alkalinity of the skin pH of the external auditory canal. These changes have been previously reported to occur in the acute stage, and their persistence may predispose to a chronic status of this condition. This prospective control study was designed to look at this possible relationship in more depth, by comparing the external auditory canal pH of individuals with chronic otitis externa, but with no current exacerbation, with an age-/sex-matched control group. Analysis of the data revealed a significantly higher external auditory canal pH in the chronic otitis externa group (P < 0.004) when compared with the controls, with no concomitant difference in body skin pH. Within this chronic otitis externa cohort, a statistically significant correlation was found between external auditory canal pH and the severity of the condition, as assessed using a multiparameter scoring system (r = 0.562; P < 0.02). Importantly, the pH was not related to the length of time since the last exacerbation. There was a significant age relationship present within our sample. Younger patients displayed more severe chronic otitis externa(r = -0.813; P < 0.001), with correspondingly higher external auditory canal pH values (r = -0.550; P < 0.02). The results suggest that alkaline ear canal skin is a local risk factor for the progression into chronic otitis externa, occurring, in this study, with greater severity in younger individuals.

Mucous membrane pemphigoid (MMP) is a sub-epithelial blistering disease that primarily involves mucosal surfaces but may also involve the skin. Clinically, it appears as vesiculobullous lesions of the oral cavity and eyes, but other tissues such as the nasopharyngeal and laryngeal mucosa can also be affected. Ultimately, scarring and airway stenosis may occur. The condition should be managed by a multidisciplinary team led by a dermatologist. Immunosuppressive therapy forms the mainstay of treatment, with surgery having both a diagnostic role and a use in the treatment of complications such as airway obstruction. There must be a low threshold of suspicion for laryngeal involvement in this group of patients, so that prompt action can be taken. Once laryngeal stenosis has occurred repeated endoscopic laser excision of scar tissue can be used to maintain an adequate airway. Adjuvant use of mitomycin-C can be used beneficially in the treatment of laryngeal complications of MMP.
