Rhinogenic Optic Neuritis Caused by Sphenoid Mucocele with Sinusitis.

A 59-year-old male who presented with a nonspecific headache at the vertex, resembling retrobulbar optic neuritis, was treated as such but did not show any improvement. Although optic nerve compression from sphenoid mucocele was finally discovered, the delayed diagnosis and improper treatment led to a permanent visual loss. Optic neuritis could be caused by a common problem, "mucocele/sinusitis," but might be easily overlooked in general practice. Rhinogenic optic neuropathy should, therefore, be considered in every case of optic neuritis whenever atypical presentation occurs or is unresponsive to high-dose steroid treatment.

The improved quality process after implementation of the hemithyroidectomy care map.

OBJECTIVE: To report the improved quality process in service care of the patients undergoing hemithyroidectomy and the results of the care map implementation. MATERIAL AND METHOD: Descriptive analysis and retrospective chart reviews were performed in the patients who underwent hemithyroidectomy in the Department of Otorhinolaryngology, Faculty of Medicine Siriraj Hospital before and after the care map implementation between January 2004 and December 2006. RESULTS: Hemithyroidectomy care map has been created with good cooperation of all members of our department in January 2005. Two hundred seventy nine patients, including 246 females (88%) and 33 males (12%) participated in this study. The care map was used in all patients. Hospital stay was reduced from five to eight days to less than four days in 93% of the patients. The estimated expenses of 97% of the patients differed from the true expense at less than 20%. Complications were minimized to the acceptable level by close supervision of the attending staffs. Incidence of vocal cord paralysis was reduced from 8.7% before the care map implementation to 2.4% and 2.3% in the first and second years. Hematoma was observed in three cases within 24 hours postoperatively and could not be prevented by drain insertion. Only minimal content was found in the drain after 48 hours. CONCLUSION: The improved quality process in hemithyroidectomy care received good cooperation from all members in our department. Effective resource utilization was achieved with maximal patients'benefit and satisfaction. Close supervision by attending staffs, meticulous surgical techniques, and adequate bleeding control are the keys of effective clinical care. Hospital stay is possibly reduced to one to two days by good pre-anesthetic care before admission and by avoiding or using drain only in selected cases for six to 48 hours.

Mastoid obliteration with postconchal soft tissue and postauricular pericranial flap.

OBJECTIVE: To report the technique and the result of mastoid obliteration with postconchal soft tissue and postauricular pericranial flap. MATERIAL AND METHOD: Retrospective chart reviews were performed in the patients who underwent mastoid obliteration after canal wall-down mastoidectomy by the first author in the Department of Otolaryngology, Faculty of Medicine Siriraj Hospital, Mahidol University between January 2004 and January 2008. RESULTS: Fifteen patients were included in the present series. All patients had final round dry cavities within six to eight weeks except one who had wet discharging cavity from accumulated keratin because of total flap atrophy. Some atrophic change at the distal part of the flap was found in five cases (33%) resulting in small pockets at attic and aditus area after a 6-month follow-up period. CONCLUSION: Postconchal soft tissue and postauricular pericranial flap were reliable for mastoid obliteration. The new cavity was finally round, dry, and healthy. It could be simply accessed, cleaned, and examined for recurrent disease during the follow-up period. Some shrinkage of the flap could be expected at the distal part after the 6-month follow-up period.

How to overcome laryngotracheal stenosis.

OBJECTIVES: To review and evaluate the outcome of the treatment of laryngotracheal stenosis (LTS). DESIGN: Descriptive review cases. SETTING: Tertiary care university hospital. PATIENTS: Series of LTS patients who were treated by the first author (TW) from January 2000 to January 2003. MAIN OUTCOME MEASURES: Leading causes of LTS, details of the lesions, therapeutic procedures, complications of treatment, time to and success in decannulation. RESULTS: Twenty-one patients (9 females and 12 males), ranging in age from 1 to 32 years old were included in the present study. Half of the patients were under 10 years old. The most common site of the lesion was the subglotic lumen (14 cases), followed by the cervical trachea (5 cases). Patients were treated using endoscopic methods (6 cases), laryngotracheal reconstruction (LTR) (9 cases), tracheal resection (3 cases), and partial cricotracheal resection (3 cases). Decannulations were achieved in 19 patients (90.5%). Endoscopic treatment succeeded within 2-4 procedures in properly selected cases. Despite LTR, multiple sessions of endoscopic laser surgery, and arytenoidectomy, decannulation was not achieved in two of the cases, both of whom had all-level laryngeal stenosis. Time to decannulation ranged from 2 to 210 days. The major causes of delayed decannulation were the presence of a large bare area of cartilaginous grafts and restenosis with granulation tissue formation CONCLUSION: Appropriate LTS treatment, which is based on the description of the lesion, results in a high decannulation rate within a proper time. Multilevel LTS, especially in the supraglottic and glottic area, is refractory to various treatment modalities, and full function of the larynx may not be restored.

Nasal granuloma gravidarum presenting with recurrent massive epistaxis.

Nasal granuloma gravidarum is a rare condition associated with pregnancy and minor trauma. This condition presents with a nasal mass with varying degree of bleeding and obstruction. We report a patient with nasal granuloma gravidarum in the third trimester of pregnancy. Surgical excision is the definite treatment for this condition in order to stop the vicious cycle of recurrent massive bleeding. Possible etiology, clinical features and management are discussed.

Outcome in pediatric tracheotomy.

OBJECTIVE: To investigate the outcome and related factors in pediatric tracheotomy. DESIGN: Retrospective chart review. SETTING: Tertiary pediatric academic hospital setting. PATIENTS: The study included 181 children below the age of 18 years who underwent 185 tracheotomies between 1991 and 1995. MAIN OUTCOMES AND MEASURES: Presenting symptoms and signs, indications, duration of follow-up, therapeutic and interval procedures, early and late complications, mortality, time to and success in decannulation. RESULTS: There were 108 (59.7%) male patients and 73 (40.3%) female patients. The average age of the children at the time of tracheotomy was 3.8 +/- 5.3 years. The majority of the children were less than 1 year of age (n = 99, 54.7%). Airway obstruction was the leading indication for tracheotomy (59.6%), followed by ventilatory support (30.4%) and pulmonary toilet (9.9%). The average duration of follow-up was 931 +/- 790 days. There were no perioperative complications. Early postoperative complications were seen in 28 (15.5%) children including 12 (6.8%) major complications and 22 (12.2%) minor complications. Late complications were seen in 115 (63.5%) children, including 8 (4.4%) major complications and 107 (59.1%) minor complications. Overall mortality rate was 13.3%, but only 1 tracheotomy-related death was caused by tube displacement. Therapeutic procedures were performed in 43% of the children, including laryngotracheal reconstruction (13%), laser excision of the lesion (5%), and supraglottoplasty (3.9%). Decannulation was accomplished in 116 (64.1%) of the children with an average of 365 +/- 388 days with tracheotomy. CONCLUSION: Tracheotomy is relatively safe in the pediatric population. Decannulation may be possible relatively quickly with resolution of the underlying problem.

Sclerosing lipogranuloma of the nose: a new treatment using adipose tissue transplantation.

We report a series of 45 patients visiting our clinic with distorted contour of the nose after having their noses augmented with injectable substances. The most common clinical presentation was a palpable mass on the dorsum of the nose, erythema with or without telangiectasia on the overlying skin, and nodularity of the nose. The onset of symptoms varied from 1 to 16 years after injection. They were treated by surgical excision, but this was always followed by a saddle-nose deformity. To correct this defect, we propose a new technique of adipose tissue transplantation that yields satisfactory results. Pathological reports of the excised mass showed a foreign body granuloma known as a sclerosing lipogranuloma (paraffinoma or siliconoma).

Ear diseases and hearing in the Thai elderly population. Part I. A comparative study of the accuracy of diagnosis and treatment by general practitioners vs ENT specialists.

The prevalence of ear disease and hearing disability in elderly Thais in 14 urban communities around Siriraj Hospital was studied. The accuracy of diagnosis and treatment of common ear diseases and of screening for hearing loss in the elderly between general practitioners (GP) and Ear, Nose and Throat (ENT) specialists was also compared. Elderly people aged 60 years or more who had registered with the health care program had their ear and hearing check-up performed by GPs and ENT specialists from mobile team. Altogether, 980 subjects were included, 332 were males, 648 were females, (male:female ratio 1:2). Their ages ranged from 60-96 years with an average age of 68.5 years. The prevalence of ear disease diagnosed by ENT specialists was 16.3 per cent (95% CI = 14.0-18.6), 12.5 per cent was external ear disease and 2.7 per cent middle ear disease. The most common ear problem was impacted ear wax (8%), the second most common problem was otitis externa (4.3%). Compared with an ENT specialist, the ability of a GP to diagnose ear diseases had a sensitivity of 46.5 per cent and a specificity of 80.3 per cent, the positive predictive value of their diagnoses was 31.5 per cent. The efficacy of the treatment of ear diseases in 51 elderly people by GPs and in 63 elderly people by ENT specialists was statistically significantly different (p = 0.02). Hearing screening by the GP using whisper or the watch test performed in 650 elderly people revealed abnormal findings (could not hear) in 70 cases or 10.8 per cent. Hearing screening using pure tone audiometry in 980 elderly people showed abnormal hearing level in 508 cases (52.4%). 9.5 per cent of them had a bilateral moderate to severe degree of hearing impairment. There was no difference in the level of hearing impairment between males and females or between right and left ears. The prevalence of hearing loss increases with increasing age. Tympanometry performed by an acoustic impedance machine in 980 of the elderly showed a conductive hearing loss in 85 cases (9.1%). The authors conclude that the prevalence of ear disease in elderly people living in the urban community around Siriraj Hospital is quite high. Although the ear diseases commonly encountered were not serious, if left untreated they may lead to complication and decreased hearing. Therefore, the proficiency of GPs in the management of common ear diseases in every community should be regularly maintained. Hearing impairment is very prevalent and increases with age. Thus, screening for hearing loss using an audiometer and/or acoustic impedance is recommended for all senior citizens in their community at least once a year. Early detection of elderly persons who could benefit from a properly fitted hearing aid will certainly improve the quality of life and may prevent psychiatric and functional impairment of the Thai elderly population.

Ear diseases and hearing in the Thai elderly population. part II. A one year follow-up study.

The ear and hearing survey of the Thai elderly in 14 urban communities around Siriraj Hospital was repeated one year after the first survey in order to detect any changes. Altogether 556 elderly people came for follow-up examination, 191 were males, 365 were females, the average age was 68.2 years (60-88 years). Ear disease was diagnosed by ENT specialists in 80 cases which implied that the prevalence of ear disease was 14.4 per cent. This was not statistically significantly different from the prevalence of ear disease in the survey conducted in the previous year and although the elderly who had ear diseases in the first survey had already been treated, the prevalence did not decrease. Some elderly people only had ear diseases in this survey. Hearing evaluation by pure tone audiometry was performed in 549 elders. There were 12.4 per cent who had bilateral, moderate to severe hearing loss which was 2.9 per cent higher than in the previous survey. The hearing level had also deteriorated in 14.3 per cent of the elderly people. Tympanometry was performed in 556 cases and showed that 10.5 per cent had a conductive hearing loss. When audiometry and tympanometry of the same elderly people were evaluated together, 49.2 per cent of them had a sensorineural hearing loss, 3 per cent had a conductive hearing loss and 6.5 per cent had a conductive or mixed type hearing loss. When the results of audiometry were compared with the self identification/perception of their hearing reported by the elderly in the questionnaires, they were not reliable. In conclusion, a one-year follow-up study of the prevalence of ear disease and hearing impairment in the elderly showed that the prevalence of ear disease was still high and had not changed significantly. Concerning hearing impairment, not only had the prevalence increased, but also the severity of hearing loss. Therefore, the authors stress the need to implement the "Ear and Hearing Care" program for the elderly both in rural and urban communities at least once a year in order to improve quality of life of the elderly Thai people and to prevent complications of ear disease.
