The stuck slide: how to unstick it.

A longitudinally folded 3 x 5 card or similar-sized stiff piece of paper can be used to release a slide stuck in a carousel without removing the carousel or its locking ring.

Flaps for cleft lip and palate surgery.

The advantages of palate repair by double opposing Z-plasty include excellent access for complete mobilization of the palatal muscles, construction of an overlapping muscle sling, and avoidance of the growth-limiting horseshoe-type scars of the hard palate that result from lateral relaxing incisions or pushback procedures. The excellent speech that results seems to justify use of the procedure. An Abbé flap designed to mimic the normal philtrum placed over an interlacing orbicularis reconstruction that is well supported superiorly can salvage a thin, scarred upper lip and improve its mobility. The lateral gingival flap provides excellent esthetic reconstruction of the cleft alveolus, secure cover over an alveolar bone graft, and ease closure of an anterior oronasal fistula.

Cleft palate repair by double opposing Z-plasty.

In an attempt to improve speech results following palate repair while allowing adequate maxillary growth, a palatoplasty using two opposing Z-plasties of the soft palate, one of the oral and one of the nasal layers, has been used in 22 infants. Eight patients had unilateral cleft lip and palate, eight had bilateral cleft lip and palate, and six had cleft palate. The Z-plasties facilitate effective dissection and redirection of the palatal muscles to produce an overlapping muscle sling and lengthen the velum without using tissue from the hard palate, which permits hard palate closure without pushback or lateral relaxing incisions. Of the 20 children old enough for speech evaluation, 18 have no velopharyngeal insufficiency. Two have very mild velopharyngeal insufficiency. None has required a pharyngeal flap.

Obstructive sleep apnea following treatment of velopharyngeal incompetence by Teflon injection.

From 1967 to 1974 a clinical trial of Teflon injection into the posterior pharyngeal wall for correction of velopharyngeal incompetence (VPI) was conducted in thirty-six patients. Six years after Teflon injection, one of the patients reported the onset of severe snoring punctuated by silences when he seemed not to be breathing, daytime hypersomnolence, and tiredness severe enough to interfere with work and studies. The diagnosis of obstructive sleep apnea (OSA) was confirmed by polysomnographic sleep monitoring, and the dynamics of the obstruction elucidated by cinefluoroscopy performed with the patient asleep. Resection of the lower 3/4 of the Teflon pad, leaving the upper rim to avoid recurrence of his VPI, has eliminated the symptoms of OSA and produced an improvement in his polysomnographic findings.

V-Y "Cup" flap for volar oblique amputation of fingers.

For fingers left shorter volarly after finger-tip amputation, a volar V-Y amputation flap designed with the V-Y portion at the middle phalanx level and using the Snow cupping technique for reconstruction of the pulp and tip has provided good sensation, padding and contour. Hypersensitivity and beaking of the nail have not been problems.

A long term study on treating velopharyngeal insufficiency by teflon injection.

Thirty-five individuals with velopharyngeal insufficiency, including eight with failed pharyngeal flaps, were treated with injectable Teflon and followed postoperatively for an average of three years. The patients' speech and voice quality were evaluated pre- and postoperatively, and an outcome was judged successful only if there was total elimination of the preoperative symptoms of hypernasality and inappropriate nasal air emission. All patients were evaluated preoperatively with cinefluorography, and an attempt was made to obtain serial postoperative films in order to determine the stability of the Teflon pad with time. An overall success rate of 74% was achieved. Success for patients with VPI, excluding those patients with pharyngeal flaps was 78%. In treating the failed pharyngeal flap cases we achieved a 62% success rate. The stability of the implanted Teflon was assessed over time as determined from measurements made on patients who received two or more postoperative cine films. Statistical analysis revealed no significant change in thickness of the pad over a period of time. Our conclusions are that with careful case selection, the injectable Teflon procedure is safe, effective and that the implant remains stable with time.
