Persistent inner ear injury after diving.

Objective: The purpose of this multiple case report was to discuss the occurrence and cause of sudden sensorineural hearing loss after diving.

Study Design: The study design was a retrospective case review.

Setting: The study was conducted at an academic tertiary referral center.

Healing of composite chondrocutaneous auricular grafts covered by skin flaps in nasal reconstructive surgery.

Objective/hypothesis: Healing of composite chondrocutaneous auricular grafts combined with overlying skin flaps for reconstruction of the internal lining in partial nasal defects should be evaluated.

Study Design: A retrospective chart review and prospective clinical follow-up of 15 patients with partial nasal defects.

Methods: Fifteen patients with partial defects of the middle and lower third of the nose were reviewed.

Can eustachian tube ventilatory function impairment after oxygen diving be influenced by application of free radical scavenger vitamins C and E?

Objectives/hypothesis: To evaluate the influence of free radical scavenger vitamins C and E on eustachian tube ventilatory function changes related to oxygen dives.

Study Design: Prospective, randomized, double-blind, placebo-controlled study of middle ear impedance changes of oxygen divers being orally treated with free radical scavenger vitamins C and E.

Methods: Fifteen divers were allocated to two groups.

Underwater application of nasal decongestants: method for special operations.

A simple method of emergency underwater application of a nasal decongestant in divers to prevent diving-related accidents or even fatalities attributable to sequelae of middle-ear and sinus barotrauma of ascent was evaluated. Eleven military divers had to inject 1 mL of 0.02% methylene blue into a central venous catheter after having inserted the tip between their upper lip and the mask at 1 m depth in a pool.

[Epidural empyema and orbital phlegmon. Computerized tomographic diagnosis of rare complications of sinusitis].

Among 4019 computed tomograms of the head performed in 2 years we found 2 epidural empyemas combined with an ipsilateral orbital phlegmon and one periorbital abscess with an incipient orbital phlegmon. In all 3 patients they turned out to be intracranial or orbital complications of an adjacent paranasal sinusitis. The CT diagnosis was a guideline for further therapy and was verified by immediate surgery.

[POR 8 (ornipressin). Local vasoconstrictive effect and hemodynamic activity during surgery in ENT clinics].

POR 8 (ornipressin) at a concentration of 5 IU in 10 ml of 1% lidocaine was used as a local vasoconstrictor in 262 ENT operations. Anaesthesia was carried out with either halothane or enflurane, or with diazepam and fentanyl. The doses of POR 8 lay between 2.

[Experiences with high-frequency jet ventilation in operations of the larynx and trachea].

60 ENT patients were ventilated with the high frequency jet ventilation method, using endotracheal catheters during 50 cases of laryngeal and 10 cases of tracheal surgery. Ventilation was carried out with equipment of type MK 800 (Acutronic Ltd.) using the following parameters; rate: 150/min, insufflation time: 30-40%, pressure: 0.

Ornipressin as vasoconstrictor in rhinosurgery.

The haemostatic effect of a high concentration of ornipressin 5 IU/10 mls lidocaine was studied in 127 patients undergoing rhinosurgery under two types of general anaesthesia. Under halothane/enflurane anaesthesia blood pressure and heart rate remained nearly constant up to 15 minutes following local injection of ornipressin into the nasal tissues. Good haemostasis was achieved in 86.
