Prospective clinical study on cochlear function after erbium:yttrium-aluminum-garnet laser Stapedotomy.
The Laryngoscope, 2005Co-Authors: Tilman Keck, H Bürner, Gunter RettingerAbstract:OBJECTIVE: To assess whether the application of the emitting erbium:yttrium-aluminum-garnet (Er:YAG) laser in Stapedotomy has negative effects on vestibular and cochlear functions.\n\nDESIGN: Prospective, with 12 to 14 months follow-up.\n\nSETTING: Academic tertiary referral center.\n\nPATIENTS: Twenty-four patients undergoing Stapedotomy (primary surgery) in otosclerosis.\n\nINTERVENTION: All patients underwent Er:YAG laser-assisted Stapedotomy for otosclerosis between January 2000 and June 2002.\n\nMAIN OUTCOME MEASURES: Early (1-3 days after surgery) and late (12-14 months after surgery) postoperative bone-conduction thresholds and the presence of post-operative tinnitus and vertigo were analyzed. In addition, the relation between applied laser energy and postoperative bone-conduction thresholds was calculated.\n\nRESULTS: In 22 patients, unchanged preoperative minus early postoperative pure-tone bone-conduction averages at 1, 2, and 4 kHz were observed. In one patient, a slight early deterioration between 10 and 20 dB was seen. In 18 patients, unchanged preoperative minus late postoperative pure-tone bone-conduction averages at 1, 2, and 4 kHz were observed. In two patients, a slight late deterioration between 10 and 20 dB was seen. In two patients, a new postoperative tinnitus was observed. No patient suffered from vertigo at the time of second evaluation. No correlation between applied laser energy and both postoperative bone-conduction thresholds was found.\n\nCONCLUSIONS: The Er:YAG laser Stapedotomy in otosclerosis is a safe technique. Vestibular and cochlear function is not significantly disturbed after Er:YAG laser Stapedotomy.

Taste Disorders after Stapedotomy
Otolaryngology-Head and Neck Surgery, 2008Co-Authors: Cristian Aedo, Carlos Stott-caro, Nicolas Albertz, Patricio TabiloAbstract:ObjectiveTo asses temporal evolution of taste disorders after Stapedotomy and its correlation with chorda tympani nerve (CTN) preservation.MethodsA retrospective study was conducted at the Department of Otolaryngology-Head and Neck Surgery of the Hospital Clinico de la Universidad de Chile between 2002 and 2007. Medical records of 141 patients with otosclerosis subject to Stapedotomy were analyzed in search for CTN preservation or section during Stapedotomy. A survey was applied to evaluate postoperative taste function and its evolution on time. Fisher's test was applied.ResultsCTN was preserved in 131 patients (93%) and sectioned in 10 patients (7%). The incidence of taste disorder was 7% (10 patients) in the CTN preservation group and 20% (2 patients) in the sectioned group (p> 0.05). All patients had full recovery of taste function before 12 months after surgery, being faster in the CTN preservation group than the sectioned group (6 months vs. 12 months respectively). Patients with section of CTN have ...

“One-shot” CO_2 versus Er:YAG laser Stapedotomy: is the outcome the same?
European Archives of Oto-Rhino-Laryngology, 2011Co-Authors: Maria Raffaella Marchese, Alessandro Scorpecci, Francesca Cianfrone, Gaetano PaludettiAbstract:To assess and compare the functional results obtained by means of multiple-shot Erbium: yttrium–aluminum–garnet (Er:YAG) laser to those obtained using “one-shot” CO_2 laser Stapedotomy in patients affected by otosclerosis. A retrospective case review was performed. Of the total number of 123 patients (114 ears) who underwent primary small-fenestra Stapedotomy from January 2006 to September 2008, seven patients who received multiple-shot laser CO_2 Stapedotomy were excluded from the study. The remaining 116 patients (104 ears) were sorted, and “one-shot” CO_2 laser Stapedotomy (group A) was performed in 35/104 and Er:YAG laser Stapedotomy (group B) in 69/104. After surgery, air conduction-pure tone average (AC-PTA) and air-bone gap (ABG) improved significantly in both groups, whereas sensorineural hearing loss (SNHL) and bone conduction (BC)-PTA did not change in both the groups. In group A, the postoperative ABG was significantly better (12.63 vs. 14.86 dB). Moreover, after “one-shot” Stapedotomy, the AC-PTA significantly improved in all tested frequencies. On the contrary, in group B the AC-PTA improved significantly only in two frequencies (0.5 and 1 kHz). Consistent with previous reports, our findings confirm that laser Stapedotomy is a safe and effective surgery, regardless of the technique. Based on our functional results, the “one-shot” CO_2 laser technique seems to be associated with a significantly better postoperative ABG if compared to Er:YAG laser Stapedotomy.

Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 2008Co-Authors: Claudio Parrilla, Jacopo Galli, Anna Rita Fetoni, Mario Rigante, Gaetano PaludettiAbstract:ObjectiveTo standardize the technical parameters of the erbium: yttrium-aluminum-garnet (Er:YAG) laser Stapedotomy.Study DesignRetrospective study of all patients with otosclerosis who underwent Stapedotomy from January 2002 to January 2006.Subjects and MethodsThe charts of 152 consecutive patients who underwent Stapedotomy were reviewed. The patients were stratified into two groups, according to the instrument used. Stapedotomies were performed in group A, with the OPMI®TwinEr: YAG laser; and in group B with manual microperforators.ResultsNo statistically significant differences were found over all measured frequencies, between pre- and postoperative bone conduction thresholds, in each group. At the last postoperative follow-up, vertigo and nystagmus were not detected; two patients in group A and one patient in group B showed persistent tinnitus.ConclusionEr:YAG laser Stapedotomy is a safe and effective procedure, with no damage of the inner ear when strict adherence to the safety parameters is observed....
