Summary: Large or multiply recurrent oronasal fistulas following cleft palate repair present a challenging problem. Nasal septal mucoperichondrial flaps have been widely used for repair of skull base defects; however, their use in the repair of oronasal cleft palate fistulas has not previously been described. In this pilot study, the authors describe anterior palatal fistula repair using a nasal septal flap and review their experience with this technique over 4 years.

Background: The CLEFT-Q includes 12 independently functioning scales that measure appearance (face, nose, nostrils, teeth, lips, jaws), health-related quality of life (psychological, social, school, speech distress), and speech function, and an eating/drinking checklist. Previous qualitative research revealed that the CLEFT-Q has content validity in noncleft craniofacial conditions. This study aimed to examine the psychometric performance of the CLEFT-Q in an international sample of patients with a broad range of facial conditions.

Objective: Autologous fat grafting of the velopharynx has been well described for the treatment of velopharyngeal insufficiency (VPI), with most studies purporting it as a technique with low morbidity useful in the treatment of mild VPI. Prompted by 3 cases of obstructive sleep apnea (OSA) following fat grafting of the velopharynx, we undertook a review of the outcomes of this procedure at our unit.

Design: Retrospective case series.

The purpose of this study was to determine the operative and ward-based requirements of burn patients as a first step in the development of a National Health Emergency Multiple Complex Burn Action Plan. A retrospective review of 1043 patients admitted to the National Burn Centre at Middlemore Hospital, Auckland, New Zealand, from June 2006 to June 2009 was undertaken. Outcome measures included the number of operative procedures, operative time, length of inpatient stay, nursing hours, and allied health hours.

Objective: There is wide international variation in the protocols used for middle ear disease management in cleft palate patients. Ventilation tube (grommet) insertion may occur routinely at the time of palatoplasty or selectively on a separate occasion if symptomatic middle ear disease develops. The audiological and otologic outcomes of cleft palate patients were studied in a single institution over a timeframe in which both protocols were utilised.

Objective: We present an audit of primary cleft palate surgery at our unit, including rates of oronasal fistula development, speech outcomes, and rates of velopharyngeal insufficiency requiring secondary surgery.

Design: A retrospective study of patients with all cleft palate types, born between January 1990 and December 2004, who underwent primary palatoplasty at Middlemore Hospital, Auckland, New Zealand.

Patients: The study included 211 patients, collectively operated on by five different surgeons.

The purpose of this study was to determine the significance of hyper-reflective corneal endothelial nuclei imaged by in vivo confocal microscopy. A retrospective analysis was performed using a database of 505 patients that had undergone in vivo confocal microscopy of the cornea. All subjects with hyper-reflective endothelial nuclei were identified and these images were analysed to determine corneal endothelial cell density and morphology.

Background: Deposits in the cornea and lens are a known complication of long-term chlorpromazine therapy.

Method: A 59-year-old woman had previously taken chlorpromazine for 20 years with doses up to 1,200 mg/day, with a mean dose of 400 mg/day. She presented with gradual onset of blurred vision in her left eye.
