Age-related tonsillar regrowth in children undergoing powered intracapsular tonsillectomy
Doshi, Hardik K; Rosow, David E; Ward, Robert F; April, Max M
OBJECTIVES: To review our experience with intracapsular tonsillectomy using powered instrumentation (PIT) in the management of tonsillar hypertrophy. DESIGN: Retrospective database review of pediatric patients undergoing PIT. METHODS: The medical records of 636 patients under 11 years of age who underwent PIT performed by the senior author (RFW), predominantly for obstructive sleep disturbance, were reviewed. Data were subsequently analyzed from 559 of these patients for clinical evidence of tonsillar regrowth, post-operative tonsillar hemorrhage, and post-operative dehydration due to pain. Specific information for possible correlation of age at the time of surgery and any increased rate of regrowth was primarily examined. RESULTS: There were a total of 33 patients who had clinical evidence of regrowth. Children less than 5 years of age had 5 times the incidence of regrowth (p<0.001). Out of the group that exhibited regrowth, 5 patients exhibited evidence of recurrent upper airway obstruction and underwent a complete tonsillectomy. The age of this complete tonsillectomy group ranged from 1.1 to 2.7 years. Out of all patients undergoing PIT, there was 1 incident of delayed post-operative dehydration due to emesis but not due to pain. There were 2 incidents of delayed post-operative tonsillar bleeds. All three complications were self-limited and did not require re-hospitalization. CONCLUSIONS: PIT is a safe procedure with a small risk of tonsillar regrowth being age related. The incidence of postoperative complications following PIT is relatively low (0.54%).

A pilot study of balloon dilation in an animal model resulting in cricoid cartilage fracture: implications for the stenotic pediatric airway
Ang, Annette H; Modi, Vikash K; Raithatha, Roheen; April, Max M; Ward, Robert F
OBJECTIVE: Endoscopic balloon dilation is increasingly popular as primary therapy for infants with subglottic stenosis. We aim to determine the maximum balloon diameter and pressure where no fracture of the cricoid would occur, minimum balloon size and pressures where a gross fracture of the cricoid occurs, and location of these fractures. We tested these objectives by performing balloon dilation in laryngotracheal complexes of eight euthanized adult male New Zealand white rabbits, with airway characteristics similar to a 3- to 9-month-old infant. METHODS: Subglottic airway diameter of each specimen was determined using endotracheal tubes (Cotton-Myer grading system). Preexistent subglottic disease was excluded by rigid endoscopy. Serial dilation with balloon catheters was performed, employing incremental balloon sizes and pressures, to determine balloon size and pressure, which resulted in a cricoid fracture. Locations of gross fractures were validated by two independent observers. RESULTS: Airway diameter of all specimens was 5.4 mm (size 4.0 endotracheal tube). Four of the seven cricoid cartilages exhibited gross fractures. Dilation with balloon diameters less than 6.0 mm failed to induce a fracture despite maximal inflation to 16.0 atmospheres. The minimum balloon size required to create a fracture was 7.0 mm, at a pressure of 6.0 atmospheres. All fractures occurred at the anterior lamina of cricoid ring. CONCLUSIONS: No fractures occurred when balloon dilation was performed with a balloon 0.6 mm or smaller than the measured subglottic diameter. Fractures of the cricoid occurred when balloon dilation was performed with a balloon 1.6 mm or larger than the subglottic diameter.

Cystic fibrosis and endoscopic sinus surgery: Relationship between nasal polyposis and likelihood of revision endoscopic sinus surgery in patients with cystic fibrosis
Rickert, Scott; Banuchi, Victoria E; Germana, Joan D; Stewart, Michael G; April, Max M
OBJECTIVES: To observe the extent of nasal polyposis endoscopically in a cystic fibrosis population before the first surgical intervention and to grade the extent using a modified Malm scale, to observe patients prospectively and record the need for revision endoscopic sinus surgery (ESS), and to compare this among the individual polyp grading groupings. DESIGN: Retrospective medical record review of data collected prospectively. SETTING: Tertiary care hospital. PATIENTS: Forty-nine consecutive patients with a clinical preoperative diagnosis of cystic fibrosis and sinusitis. MAIN OUTCOME MEASURES: Using a modified Malm scale, the extent of polyps was prospectively graded into 3 groups before the first surgical intervention. The number of patients needing revision ESS and the mean time to revision ESS were compared among the 3 groups. RESULTS: Forty-nine consecutive patients underwent ESS between 1992 and 2007. We used a 3-stage system for extent of polyposis: 16 patients were noted to have no polyps (grade A), 14 had mild polyposis (grade B), and 19 had extensive polyposis (grade C). During the study, 14 patients required revision surgery: 3 with mild polyps and 11 with extensive polyps. Mean time to revision surgery was 39.7 months for those with grade B and 23.8 months for those with grade C. In the overall statistical analysis, the rate of revision ESS was significantly different among the 3 groups (P < .001). In pairwise comparisons, there were significant differences between those with grades A and C (P < .001) and between those with grades B and C (P = .04) and a trend toward significance between those with grades A and B (P = .052). There were no complications from ESS. CONCLUSION: Preoperative grading of nasal polyposis in patients with cystic fibrosis can help assess the future likelihood of revision ESS

Sialodochostomy as treatment for imperforate submandibular duct: a systematic literature review and report of two cases [Case Report]
Rosow, David E; Ward, Robert F; April, Max M
OBJECTIVE: To better understand the diagnosis, treatments, and outcomes of congenitally imperforate salivary ducts. METHODS: A systematic literature review was performed using the following terms: imperforate submandibular duct, imperforate Wharton's duct, congenital atresia submandibular duct, congenital atresia sublingual duct, and congenital ranula. Only papers focusing on congenital floor of mouth cysts arising from imperforate salivary ducts were included. Two additional patients from our own experience are also discussed. RESULTS: Seventeen papers published since 1950 met inclusion criteria. A total of 26 patients underwent therapy ranging from mere observation to complete excision of the cyst with the sublingual gland. Both of our 2 additional patients both underwent simple sialodochostomy (excision of the imperforate sublingual caruncle) with cyst decompression. For all 28 patients, there have been no reported recurrences, with mean follow-up of 24.8 months and median follow-up of 14.8 months. CONCLUSIONS: Congenital floor of mouth cysts arising from imperforate salivary ducts are rare, but they may mimic the appearance of a ranula. Unlike ranulas, these cysts may be safely and effectively cured by simple sialodochostomy. To date, 26 other cases have been described in the literature, and nearly all have been successfully treated with simple incision or marsupialization without recurrence. Care should be taken to exclude ranula as a diagnosis, as incomplete excision may likely result in recurrence.

Reduction in surgical innovation, 1988 to 2006
Rosow, David E; Likhterov, Ilya; Stewart, Michael G; April, Max M
OBJECTIVE: We hypothesize that increasing regulation of human subject research has reduced the number of published reports of surgical innovation in otolaryngology. STUDY DESIGN: A systematic review of a predetermined subset of otolaryngology literature. METHODS: We randomly selected half of the articles published in 1988 and 2006 in three prominent journals. After identifying information was concealed, abstracts were classified independently by two authors into three groups: innovation, modification, or neither. Disagreements were resolved by a third author who read the entire article. Proportions were compared with chi(2) analysis. RESULTS: The proportion of articles classified as innovation or modification decreased significantly from 67 of 367 (18.3%) in 1988 to 59 of 548 (10.8%) in 2006 (P = 0.001). The elimination of radiology and pathology quiz cases yielded similar results: 11.1 percent vs 18.9 percent, P = 0.001. Innovation or modification in animal model research also decreased (0.9% vs 3.8%, P = 0.003). Overall, only 4 articles were actually classified as true innovation. CONCLUSIONS: The frequency of true innovation was low in both years, but articles that described surgical modifications decreased significantly over this 18-year period. One reason may be increased administrative barriers for clinical research approval. Although our analysis cannot determine cause and effect, it is an important finding that deserves further study.

Minimally invasive techniques in laryngotracheal reconstruction
Lando, Tali; April, Max M; Ward, Robert F
The treatment of laryngotracheal stenosis has evolved over the past several decades. Advances in technology, equipment and medication have increased our ability to treat some airway stenosis in a minimally invasive manner, and at times by an endoscopic method. With improved precision, our results with postoperative voice and swallowing should improve

Recurrent periorbital cellulitis: an unusual clinical entity [Case Report]
Sorin, Alexander; April, Max M; Ward, Robert F
OBJECTIVES: To discuss the cause and management of recurrent periorbital cellulitis (RPOC). STUDY DESIGN: Retrospective case series and review of literature. MATERIALS AND METHODS: In the past 11 years, we have treated 6 patients for recurrent periorbital cellulitis (RPOC). Inclusion criteria were a minimum of 3 episodes of periorbital cellulitis (POC) within a 1-year period, with interval convalescence lasting at least 1 month. All patients were followed for at least 1 year after resolution. RESULTS: The causes of RPOC were as follows: (1) 2 patients developed RPOC attributed to environmental allergies; (2) 1 was diagnosed with underlying recurrent sinusitis resistant to medical management with resolution attained through surgery; (3) 1 patient with vesicular RPOC was diagnosed with herpetic RPOC and treated medically with antiviral therapy; (4) 1 patient had allergic contact dermatitis from cosmetic make-up use; and (5) 1 patient was suspected of malingering via repeat subcutaneous self-injection of an irritant. CONCLUSIONS: Although periorbital cellulitis is a commonly encountered and treatable condition, recurrent periorbital cellulitis is rare and may be challenging to manage. In our experience, the causes of recurrence varied, but resolution was achieved by identifying the underlying cause through continuous clinical reassessment and by appropriate medical or surgical management.

Topical antibiotic induced otomycosis
Jackman, Alexis; Ward, Robert; April, Max; Bent, John
Prior to 1999, the diagnosis of otomycosis as a cause of persistent otorrhea was rare. An increase incidence has been seen in among our outpatient pediatric otolaryngology practice. The purpose of this study is to assess the contribution of ototopical antibiotic drops to the development of otomycosis. DESIGN: Retrospective study. SETTING: Pediatric otolaryngology outpatient center. METHODS: Chart review of all patients diagnosed with otomycosis between June 1999 and September 2001. Twenty-six patients (ages 17 months-29 years) were diagnosed with otomycosis based on clinical and microbiological findings after treatment with topical ofloxacin antibiotic drops. All patients had used ototopical antibiotics, including ofloxacin in every case, for presumed bacterial otorrhea. Once the fungal source was recognized, therapy succeeded in each case (26/26). Physicians need an elevated suspicion of otomycosis as a cause of persistent otorrhea, especially following treatment with topical antibiotic drops. Appropriate treatment of otomycosis eliminates otorrhea. Ofloxacin remains an excellent choice for bacterial otorrhea, but it appears to increase the incidence of otomycosis. Thus, its usage warrants careful post-treatment follow-up.
