AbstractObjectives:To describe the feasibility and assess the safety of using an ultrasonic bone aspirator in endoscopic ear surgery.Methods:Five temporal bones were dissected via endoscopic ear surgery using a Sonopet ultrasonic bone aspirator. Atticoantrostomy was undertaken. Another four bones were dissected using routine endoscopic equipment and standard bone curettes in a similar manner. Feasibility and safety were assessed in terms of: dissection time, atticoantrostomy adequacy, tympanomeatal flap damage, chorda tympani nerve injury, ossicular injury, ossicular chain disruption, facial nerve exposure and dural injury.Results:The time taken to perform atticoantrostomy was significantly less with the use of the ultrasonic bone aspirator as compared to conventional bone curettes.Conclusion:The ultrasonic bone aspirator is a feasible option in endoscopic ear surgery. It enables easy bone removal, with no additional complications and greater efficacy than traditional bone curettes. It should be a part of the armamentarium for transcanal endoscopic ear surgery.

Laser Effect

Facial palsy that occurs immediately after middle ear surgery (stapedectomy, stapedotomy, and tympanoplasty) can be a consequence of the local anesthetics and it regresses completely within a few hours. In the case of delayed facial palsy, the alarming symptom occurs several days or even weeks after uneventful surgery. The mechanism of the neural dysfunction is not readily defined. Surgical stress, intraoperative trauma, or laceration of the chorda tympani nerve with a resultant retrograde facial nerve edema can all be provoking etiological factors. A dehiscent bony facial canal or a multiple microporotic fallopian canal (microtrauma or laser effect) can also contribute to the development of this rare phenomenon. The most popular theory related to the explanation of delayed facial palsy at present is the reactivation of dormant viruses. Both the thermal effect of the laser and the elevation of the tympanomeatal flap can reactivate viruses resting inside the ganglion geniculi, facial nerve, or facial nuclei. The authors report the case histories of a 55-year-old female, and a 45-year-old male who presented with a delayed facial palsy following laser stapedotomy. The clinical characteristics, the therapeutic options, and the possibility of prevention are discussed.

Facial nerve neuromas occur throughout the course of the facial nerve and its branches, however lesions occurring on the chorda tympani branch are exceptionally rare.We present a case where the diagnosis was made intra-operatively; the patient was pre-operatively thought to have had a cholesteatoma.Total resection is the treatment of choice for these cases. Early diagnosis, aided by high resolution computed tomography (CT) scanning, will facilitate complete excision without damage to the facial nerve itself or the ossicular chain. The slow growing nature of the neuroma is likely to allow compensatory mechanisms to occur without the patient experiencing dysgeusia. As with any rarity the diagnosis can only be made with a high index of suspicion.

A Prospective Study

This is a prospective study that looks into the prevalence of chorda tympani nerve (CTN) injury and related symptoms following varying degrees of trauma to the nerve during three common types of middle-ear operation: myringoplasty, tympanotomy and mastoidectomy. The number of patients with CTN-related symptoms varied widely between the three groups. Increased occurrence of the nerve related symptoms and a prolonged recovery time were observed in the tympanotomy group. Stretching of the nerve produced more symptomatic cases than cutting it in the myringoplasty and mastoidectomy groups. Recovery was complete in 92 per cent of the symptomatic patients by 12 months. It is important to inform patients about the possibility of CTN injury during middle-ear operations, and it should also be emphasized that symptoms related to CTN injury can occur irrespective of the type of damage to the nerve.
