Eye observation and corneal protection during endonasal surgery.

Traumatic orbital complications of endonasal surgery, although rare, are a cause of significant morbidity. Although a variety of methods of monitoring eye function during surgery have been described, the best method remains direct perioperative observation of the eye. However, the eye must also be protected during surgery otherwise corneal drying will occur and corneal abrasion may result. This article describes and illustrates the use of Geliperm, a sterile, transparent, pliant hydrogel dressing, as a corneal protector allowing continuous observation of the eye during endonasal surgery.

The treatment of acute dacryocystitis using laser assisted endonasal dacryocystorhinostomy.

AIMS: To determine whether acute dacryocystitis complicated by abscess formation can be successfully treated using laser assisted endonasal dacryocystorhinostomy. METHODS: A protocol was adopted for the management of acute dacryocystitis presenting to an ophthalmology department. All patients were assessed jointly by an ophthalmologist and otolaryngologist for their suitability for primary internal drainage via a nasal endoscopic approach. All suitable patients during the study period August 1999 to November 2000 were managed by intravenous antibiotics and holmium:YAG laser dacryocystorhinostomy. RESULTS: Nine patients were studied (mean age 72 years (range 38-82 years), three men, six women). A history of chronic epiphora was found in 78% of patients, and recurrent nasolacrimal infections in the same 78%. Resolution of symptoms and signs of acute dacryocystitis occurred in all nine patients. No recurrence of acute dacryocystitis occurred during the median follow up period of 11 months (range 6-31 months). Ostium patency defined as the absence of epiphora and the observation of irrigated lacrimal fluorescein at the ostium was achieved in 67% of patients. Epiphora recurred in 33% of cases. CONCLUSION: Laser assisted endonasal dacryocystorhinostomy is an effective primary treatment in cases of acute dacryocystitis complicated by abscess formation. In addition, pre-existing symptoms of epiphora and recurrent nasolacrimal infections are relieved in the majority of patients.

Detection of extrinsic bronchial compression during foreign body removal by pulse oximetry.

A case of stridor is described which was due to the presence of a foreign body in the larynx of an infant. Following partial removal, compression of the right main bronchus was detected because of continuing low arterial oxygen saturation. The use of pulse oximetry allowed this complication to be identified, and the advantages of this method of monitoring are discussed.

Aural polyps and cholesteatoma.

A retrospective review of 200 cases of aural polypectomy performed in Glasgow and London was assessed in previously unoperated ears and in those with mastoid cavities. In those with mastoid cavities 72% of the ears became dry whilst only 33% were dry in the previously unoperated group. Cholesteatoma was found in 33% of previously unoperated ears and in 71% with an attic or posterior marginal defect. It can be concluded from these results that aural polypectomy in the presence of a mastoid cavity is a satisfactory procedure but in a previously unoperated ear a more radical procedure should be considered because of its frequent association with underlying cholesteatoma.
