Introducción: La desviación de la punta nasal suele producir alteración estética y funcional nasal. Generalmente, asocia alteraciones morfológicas de los cartílagos alares, además de dismorfia del cartílago septal. Objetivo: Presentar una técnica quirúrgica alternativa para el tratamiento de la laterorrinia en tercio inferior nasal y sus resultados. Material y Método: Se trataron 27 pacientes con una laterorrinia en punta nasal con la técnica del septum bisagra, incluyendo la colocación de uno o dos injertos de expansión. Describimos el protocolo de anamnesis y exploración que seguimos en estos pacientes y la descripción detallada de la técnica quirúrgica. Resultados: En 19 pacientes se utilizó un injerto de expansión unilateral para completar la técnica y en ocho de forma bilateral. Se obtuvo una puntuación media en la escala visual analógica (EVA) de ventilación de 8,3, con una mejoría de seis puntos, y en la EVA de aspecto estético de 8,1, mejorando en 4,6 puntos. Conclusión: la utilización de la técnica del septum bisagra es beneficiosa para el tratamiento de la desviación de la punta nasal, tanto a nivel funcional como estético. Presenta ciertas diferencias frente a otras técnicas descritas. La indicación se debe adecuar a cada paciente de manera individualizada.
Introduction: Deviation of nasal tip usually produces aesthetic disturbance and nasal ventilation decrease. It is usually associated with alar cartilages morphologic disturbances and dysmorphia of the septal cartilage. Aim: To present an alternative surgical technique for treating laterorrhinia in the nasal inferior third and its outcomes. Material and Method: 27 patients with nasal tip laterorrhinia were treated with the hinge septum technique, including the placement of one or two spreader grafts. We describe the anamnesis and exploration protocol that we carried out in these patients and a detailed description of the surgical procedure. Results: Unilateral spreader graft was used in 19 patients to complete the technique, and bilateral spreader graft was used in eight. The average score in visual analogue scale (VAS) related to nasal flow was 8.3, which means an improvement of six points, and in VAS related to aesthetic appearance the score was 8.1, improving 4.6 points. Conclusion: The use of the hinge septum technique is useful to treat the deviation of the nasal tip in a functional and aesthetic way. There are several differences compared to other described techniques. The indication has to be suitable for each patient individually.

BACKGROUND AND OBJECTIVE: Osseointegrated auditory devices are hearing gadgets that use the bone conduction of sound to produce hearing improvement. The mechanisms and factors that contribute to this sound transmission have been widely studied, however, there are other aspects that remain unknown, for instance, the influence of the processor power output. The aim of this study was to know if there is any relationship between the power output created by the devices and the hearing improvement that they achieve. MATERIALS Y METHODS: 44 patients were implanted with a percutaneous Baha® 5 model. Hearing thresholds in pure tone audiometry, free-field audiometry, and speech recognition (in quiet and in noise) were measured pre and postoperatively in each patient. The direct bone conduction thresholds and the power output values from the processors were also obtained. RESULTS: The pure tone average threshold in free field was 39.29â¯dB (SDâ¯=â¯9.15), so that the mean gain was 29.18â¯dB (SDâ¯=â¯10.13) with the device. This involved an air-bone gap closure in 63.64% of patients. The pure tone average threshold in direct bone conduction was 27.6â¯dB (SDâ¯=â¯10.91), which was 8.4â¯dB better than the pure tone average threshold via bone conduction. The mean gain in speech recognition was 39.15% (SDâ¯=â¯23.98) at 40â¯dB and 36.66% (SDâ¯=â¯26.76) at 60â¯dB. The mean gain in the signal-to-noise ratio was -5.9â¯dB (SDâ¯=â¯4.32). On the other hand, the mean power output values were 27.95â¯dB µN (SDâ¯=â¯6.51) in G40 and 26.22â¯dB µN (SDâ¯=â¯6.49) in G60. When analysing the relationship between bone conduction thresholds and G40 and G60 values, a correlation from the frequency of 1000â¯Hz was observed. However, no statistically significant association between power output, functional gain or speech recognition gain was found. CONCLUSIONS: The osseointegrated auditory devices generate hearing improvement in tonal thresholds and speech recognition, even in noise. Most patients closed the air-bone gap with the device. There is a direct relationship between the bone conduction threshold and the power output values from the processor, but only in mid and high frequencies. However, the relationship between power output and gain in speech recognition is weaker. Further investigation of contributing factors is necessary.

Antecedentes y objetivos: Los dispositivos auditivos osteointegrados utilizan la transmisión del sonido por vía ósea para producir una mejoría auditiva. Los mecanismos y factores que intervienen en esta transmisión han sido ampliamente estudiados, sin embargo, existen otros aspectos que no conocemos, por ejemplo, la influencia que tiene la potencia de salida del procesador. El objetivo principal de este estudio fue conocer si existe alguna relación entre la potencia que emiten estos dispositivos y la mejoría auditiva que producen. Materiales y métodos: Hemos realizado un estudio en 44 pacientes portadores de un Baha® 5 percutáneo. De cada paciente se obtuvieron los umbrales de vía aérea y ósea en audiometría tonal liminar, en audiometría en campo libre, y en audiometría verbal en silencio y con ruido de fondo, tanto previa como posteriormente a la implantación. También se recogieron los umbrales de conducción ósea directa a través del procesador y los valores de ganancia en la potencia de salida del procesador. (AU)
