isolated Nasalis Muscle reconstruction in secondary unilateral cleft lip nasal reconstruction
Laryngoscope, 1999Co-Authors: Marijo Bagatain, Morad M Khosh, Gary Nishioka, Wayne F LarrabeeAbstract:Objectives/Hypothesis: Reconstruction of the Nasalis Muscle in the unilateral cleft lip nasal deformity improves surgical results. Study Design: A retrospective analysis of a series of 112 consecutive procedures. Methods: Chart review and analysis of standardized preoperative and postoperative clinical photographs. Results: Patients treated with this technique had improved contour of the alar base compared with historical controls. Conclusion: Nasalis Muscle reconstruction should be considered in the repair of the moderate to severe unilateral cleft nose deformity.

modified single sling myocutaneous island pedicle flap series of 61 reconstructions
Dermatologic Surgery, 2008Co-Authors: Andrea Willey, Diamondis J Papadopoulos, Neil A Swanson, Ken K LeeAbstract:BACKGROUND Bilevel undermining above and below the transverse Nasalis Muscle in the construction of a myocutaneous island pedicle flap produces a bilateral or unilateral muscular sling with exceptional vascular supply for reconstruction of defects on the distal nose. We present further modification of the single-sling myocutaneous island pedicle flap that expands its application to a wide variety of nasal defects and further defines its usefulness in nasal reconstruction. METHODS A series of 61 consecutive myocutaneous island pedicle flap reconstructions performed after Mohs surgery between March 2005 and July 2006 are presented. Flap modifications are presented, and advantages and limitations are discussed. RESULTS Flap modifications introduce additional reach and rotational mobility to the flap that permit extension of the flap to defects on the nasal tip and distal ala. CONCLUSION Modifications of the bilevel approach to the single-sling Nasalis myocutaneous island pedicle flap further define its practicality in nasal reconstruction and expand its application to a variety of nasal defects.

decremental response of the Nasalis and hypothenar Muscles in myasthenia gravis
Muscle & Nerve, 2003Co-Authors: Erik H Niks, Umesh A Badrising, Jan J G M Verschuuren, Gert J Van DijkAbstract:Repetitive nerve stimulation (RNS) is a standard diagnostic procedure in myasthenia gravis (MG). Although RNS sensitivity is highest in weak Muscles, RNS is easier to perform in distal Muscles that are often not affected. Twenty-five patients with MG were assessed to compare the sensitivity of RNS of the Nasalis Muscle to that of the hypothenar Muscles. Abnormal decrement was found in hypothenar Muscles in 9 patients (36%) and in the Nasalis Muscle in 13 patients (52%). RNS of the Nasalis Muscle appeared more useful to detect abnormal neuromuscular transmission in patients with oculobulbar MG (5 of 5) than hypothenar RNS (1 of 5). In patients with generalized MG, hypothenar Muscles had a similar yield of abnormal RNS tests.

repetitive nerve stimulation of the Nasalis Muscle technique and normal values
Muscle & Nerve, 2002Co-Authors: Astrid Ruysvan E W M Oeyen, Gert J Van DijkAbstract:A technique of repetitive nerve stimulation of the facial nerve with recording from the Nasalis and orbicularis oculi Muscles was developed and tested in 15 healthy subjects. Quality criteria were that the stimulus artifact should return to baseline before the onset of the compound Muscle action potential (CMAP), and that the CMAP should begin with a negative phase, be biphasic in shape, and have an amplitude of over 1 mV. Repetitive nerve stimulation was only performed if all four criteria were met, which was the case in all 15 subjects for the Nasalis Muscle, but in only 5 subjects for the orbicularis oculi Muscle. The largest observed decrement was 9% in area. Reptitive nerve stimulation of the Nasalis Muscle is thus feasible, but its diagnostic utility remains to be established in patients with disorders of neuromuscular transmission.

nasal reconstruction using a myocutaneous island pedicle flap based on the Nasalis Muscle with bilevel undermining review of 57 cases
Annals of Plastic Surgery, 2021Co-Authors: Farzad R Nahai, Diamondis J Papadopoulos, John Paul Papadopoulos, Paris Thatos, Iviensan F ManaloAbstract:BACKGROUND Nasal reconstruction after Mohs resection of skin cancer commonly uses local flaps, many of which present limitations concerning their movement and skin color/texture match. In this article, the use of a myocutaneous island pedicle flap based on the Nasalis Muscle with bilevel undermining for the management of defects at challenging locations on the nose is described as a versatile and cosmetically appropriate flap option. In addition, a novel mathematical sizing methodology for this flap is presented. METHODS Between March 2013 and May 2016, 57 patients having undergone Mohs resection of skin cancer underwent nasal reconstruction using a myocutaneous island pedicle flap based on the Nasalis Muscle with bilevel undermining at our clinic. During the postoperative follow-up, patients were monitored for complications and received proper wound care. RESULTS The mean age was 68.4 (range, 34-94) years. The mean follow-up was 10.1 (range, 3.0-34.9) months. The mean defect size was 1.99 (range, 0.70-5.25) cm2. No complete losses of flap occurred. Incidence of minor complications (pin cushion effect, minor delayed healing, etc) was minimal (4/57; 7.0%). Two of the cases in this series involved the utilization of cartilage grafts in combination with the myocutaneus island pedicle flap. CONCLUSIONS The myocutaneous island pedicle flap based on the Nasalis Muscle with bilevel undermining can be used as a versatile flap for the closure of defects of various sizes and locations on the nose because of its rich blood supply, ease and convenience of use, and highly acceptable cosmetic outcome.
