Abstract
We investigated the feasibility of using laser tissue welding techniques to perform transcanal underlay tympanoplasty. We used 10 temporal bones obtained from human cadavers. After creating a subtotal tympanic membrane perforation, we introduced harvested periosteum through the perforation and used laser tissue welding to secure the periosteum graft in place in an underlay fashion. The procedure was performed via a transcanal approach and did not require middle ear packing. Immediately after the graft had been placed, we qualitatively tested its integrity with a blunt probe. The graft was as strong as the native cadaver tympanic membrane in all 10 cases. We conclude that laser transcanal underlay tympanoplasty is a feasible and effective method of repairing a tympanic membrane. The ultimate goal is to develop a technique that will allow physicians to routinely perform underlay tympanoplasty on moderately sized perforations in an office setting.

The mechanical reduction of early acquired cholesteatomas in children: Indications and limitations

Abstract
The standard treatment for acquired cholesteatoma involves surgical removal of the lesion and reconstruction of the tympanic membrane. In some children, these lesions can be treated more conservatively. We conducted a retrospective study of 29 ears in 24 children who had been treated for early acquired cholesteatoma with mechanical reduction and a tympanostomy tube. Outcomes measures included hearing status, the postoperative appearance of the tympanic membrane, and the need for additional surgery. We found that anterior and inferior pars tensa lesions, with or without squamous debris, can be successfully reduced, but that posterosuperior retractions respond less well when the ossicular chain has been eroded. None of the children who responded to mechanical reduction required major reconstructive surgery later. We conclude that mechanical reduction of retraction pocket cholesteatomas with tympanostomy tube placement is sufficient to restore normal hearing and a normal tympanic membrane appearance in selected children with early lesions. We also identified several important prognostic features, including the patient's age, the specific location of the retraction pocket on the tympanic membrane, the extent of the pocket, ossicular chain involvement, and the patient's adenoid status.
